Description

Speaker and drum paper, manufacturing method and sound producing method, and sound effect device

Technical field

The present invention relates to the field of loudspeakers, and in particular to a loudspeaker and its drum paper, manufacturing method and sound generation method. The present invention also relates to a sound effect device, wherein the sound effect device includes the speaker and a passive vibrator capable of vibrating and making sound in response to the vibration of the speaker, so as to enhance the low-frequency sound effect of the sound effect device through the passive vibrator.

Background technique

Sound devices such as speakers are generally composed of a speaker frame, a drum paper, a voice coil and a magnetic return system. The outer edge of the drum paper extends to and is connected to the speaker frame, and the inner edge of the drum paper extends to and is connected to the voice coil, which is electromagnetically inductively connected to the magnetic return system, so that when an audio signal is input to the magnetic return system, the magnetic return system electromagnetically drives the voice coil in response to the input of the audio signal During the movement of the voice coil, the voice coil drives the drum paper to reciprocate synchronously, so that the drum paper agitates air to produce sound. In order to obtain better sound effects from the sound device, the sound device also provides an elastic wave. The inner side of the elastic wave is connected to the voice coil, and the outer side of the elastic wave is connected to the speaker frame. The wave limits the movement of the voice coil in one direction to prevent the voice coil from shaking during movement, thereby reducing or even avoiding noise from the sound device.

In order to ensure the sound effect of the sound device in the prior art, the drum paper is designed and provided in a circular shape, and the drum paper is driven to move by the voice coil at the middle position of the drum paper, so as to make the movement of each position of the drum paper in the circumferential direction synchronized and consistent in amplitude as much as possible. If the drum paper is designed and provided in a non-circular shape, for example, the drum paper is designed and provided in a racetrack shape, the racetrack-shaped drum paper will have a long axis direction and a short axis direction. If the voice coil is still set in the middle position of the drum paper to drive the drum paper to move, due to the principle of force conduction, the force on the drum paper in the long axis direction and the short axis direction is uneven. For example, in the long axis direction, the part farther away from the middle position of the drum paper is subjected to less force driven by the voice coil. Even in extreme cases, especially in the length direction of the drum paper, when the voice coil first generates a driving force to drive the drum paper to move in a direction away from the magnetic loop system, according to the principle of force conduction, the driving force will first drive the part in the middle position of the drum paper to move in a direction away from the magnetic loop system, and then when the driving force is conducted to the drum paper, the drum paper will be driven to move in a direction away from the magnetic loop system. When the voice coil generates a driving force for the second time to drive the drum paper to move in the direction close to the magnetic loop system, the driving force will also first drive the middle part of the drum paper to move in the direction close to the magnetic system. At this time, there will be a situation that the driving force generated by the voice coil for the first time is transmitted to the edge of the drum paper and the driving force generated by the voice coil for the second time is applied to the middle part of the drum paper at the same time, resulting in the movement direction of different positions of the drum paper being opposite. This will seriously offset the amount of air agitated by the drum paper on the one hand, and on the other hand, it will cause the circumferential movement of the drum paper to be uneven or even wave-shaped, resulting in a serious reduction in sound quality. It can be understood that the greater the difference between the long axis direction and the short axis direction of the drum paper, the more obvious the above-mentioned adverse effect. That is to say, limited by the structure and circular shape of the drum paper, the sound device in the prior art can only be designed to be circular or roughly circular. Such a shape limits the expansion of the design ideas and application ideas of the sound device, thereby causing the sound device to be unable to meet the increasingly personalized design needs in the market.

In addition, the volume of the sound of the sound device is related to the amount of air agitated by the drum paper, and the amount of air agitated by the drum paper is related to the power of the audio signal input into the magnetic loop system and the area of the drum paper. For example, under the premise that the area of the drum paper is fixed, by increasing the power of the audio signal input into the magnetic loop system, the drum paper can have a larger stroke to increase the amount of air agitated by the drum paper, thereby improving the sound effect of the sound device. Since the drum paper of the sound device in the prior art can only be designed to be circular or roughly circular, the effect of increasing the sound of the sound device can only be achieved by controlling the power of the audio signal input into the magnetic loop system in the prior art, which not only places higher and higher requirements on the power amplifier matched with the sound device, but also greatly increases the cost of the sound device and the power amplifier matched with the sound device. Obviously, this approach cannot be accepted and recognized by the market. More importantly, since the stroke of the sound device needs to be increased to increase the amount of air agitated by the drum paper, the size of the sound device becomes larger, which is not conducive to the development of the sound device towards the direction of lightness and thinness, nor is it conducive to the sound device being applied to electronic devices that pursue lightness and thinness. For example, in recent years, portable electronic devices such as smart phones have been increasingly moving toward being thinner and lighter, and this development trend of the sound device has caused the development direction of the sound device and the portable electronic device to run counter to each other.

Referring to Figures 1 to 6 of the accompanying drawings of the specification, a speaker 100 according to a preferred embodiment of the present invention will be explained. The speaker 100 can generate sound by agitating air in response to the input of an audio signal, wherein the speaker 100 comprises a support unit 10, a magnetic return unit 20, a voice coil 30 and a drum paper 40. The magnetic return unit 20 and the voice coil 30 are coupled, for example, the magnetic return unit 20 and the voice coil 30 are connected together by electromagnetic induction, and the drum paper 40 is arranged between the support unit 10 and the voice coil 30, wherein the drum paper 40 can be driven by the voice coil 30 to agitate air so that the speaker 100 generates sound, and the support unit 10 is used to limit the stroke of the drum paper 40 when it is driven. It can be understood that the greater the amount of air agitated by the drum paper 40 at a single time, the greater the volume of the speaker 100.

The drum paper 40 has an inner portion 41 and an outer portion 42, wherein the inner portion 41 of the drum paper 40 extends inwardly to be connected to the voice coil 30, and the outer portion 42 extends outwardly. is connected to the support unit 10, so that the drum paper 40 is located between the voice coil 30 and the support unit 10, wherein the voice coil 30 is used to drive the drum paper 40 to blow air, and the The support element 10 limits the stroke of the drum paper 40 .

Preferably, the middle portion of the drum paper 40 is hollow so that the inner portion 41 of the drum paper 40 can be connected along the outer circumference of the voice coil 30 and the outer circumference of the voice coil 30 , that is, the drum paper 40 may have a central through hole.

The magnetic return unit 20 is suitable for being connected to an audio signal source, such as the audio signal source formed by electronic devices such as mobile phones and music players. When the magnetic return unit 20 responds to the input of the audio signal from the audio signal source, according to the principle of electromagnetic induction, the magnetic return unit 20 can drive the voice coil 30 to move back and forth along the vertical axial direction. For example, the z-axis direction shown in Figure 1 is the vertical axial direction defined in the present invention. The voice coil 30 further drives the drum paper 40 to move back and forth along the z-axis direction, so that the drum paper 40 can agitate the air in the vertical axial direction to generate sound.

It is worth mentioning that the connection method between the magnetic return system 20 and the audio signal source is not limited. For example, the magnetic return system 20 and the audio signal source can be connected through a wired or wireless connection, so that The magnetic return system 20 is capable of receiving and responding to audio signals radiated by the audio signal source.

In another embodiment of the present invention, the inner portion 41 of the drum paper 40 extends inward to be connected to the voice coil 30, and the outer portion 42 of the drum paper 40 may form a free side, That is, the outer portion 42 of the drum paper 40 is not connected to the support unit 10 .

Further, according to FIG. 2 and FIG. 3 , the speaker 100 further includes a limiting mechanism 50 . The limiting mechanism 50 is disposed between the supporting unit 10 and the voice coil 30 . The limiting mechanism 50 The mechanism 50 can produce deformation, and the limiting mechanism 50 is used to limit the movement of the voice coil 30 in the vertical axial direction without deflection. In this way, the sound effect of the speaker 100 can be ensured. In the embodiment shown in FIG. 3 , the limiting mechanism 50 may be a corrugated sheet made of soft material, and due to the wrinkles of the limiting mechanism 50 , the limiting mechanism 50 has the ability to shape-shift. In another embodiment of the present invention, the limiting mechanism 50 can also be implemented as a smooth sheet body or a hollow sheet body to have the ability to deform.

Referring to Figures 1 and 2, the support unit 10 includes a speaker frame 11 and a suspension 12. The magnetic return unit 20 and the limiting mechanism 50 are respectively provided on the speaker frame 11. Both sides of the flange 12 extend in a curved manner to be connected to the speaker frame 11 and the outer portion 42 of the drum paper 40 respectively.

In the present invention, the hanging edge 12 is made of elastic material, and the hanging edge 12 is used to limit the movement of the drum paper 40 in the vertical axial direction without causing shaking and tilting. When the drum paper 40 is driven by the voice coil 30 to move upward along the vertical axial direction, the hanging edge 12 pulls the outer portion 42 of the drum paper 40 to cause the drum paper 40 to move upward. downward trend and displacement; similarly, when the drum paper 40 is driven by the voice coil 30 to produce downward movement and displacement along the vertical axial direction, the hanging edge 12 pulls the drum paper 40 The outer portion 42 causes the drum paper 40 to have an upward tendency and displacement.

Those skilled in the art can understand that the voice coil 30 can actively drive the drum paper 40 to produce an upward or downward trend and displacement along the vertical axial direction, and the hanging edge 12 can passively pull the drum paper 40 upward or downward. The drum paper 40 has movement and displacement along the vertical axial direction to return to the initial position. It is worth mentioning that the cross-sectional shape of the overhang 12 may be arched, wavy, S-shaped, inverted U-shaped, or pleated, or other shapes, although the overhang shown in FIG. 3 The cross section of the side 12 is arched, but those skilled in the art can understand that the hanging side 12 with an arched cross section shown in FIG. 3 is only an example, which does not limit the content and scope of the present invention. scope.

In one embodiment of the present invention, the hanging edge 12 and the drum paper 40 are formed separately and then assembled together. For example, the hanging edge 12 and the outer sides of the drum paper 40 can be glued together. Part 42 is glued together. In another embodiment of the present invention, the hanging edge 12 and the drum paper 40 can also be integrally formed. For example, in a specific embodiment of the present invention, the hanging edge 12 and the drum paper 40 can be integrally formed. The drum paper 40 can be integrally formed using an insert injection process. In this way, on the one hand, the connection between the hanging edge 12 and the drum paper 40 can be transitioned more evenly, thereby making the drum paper smoother in the future. The movement of each position of the drum 40 in the circumferential direction is synchronous and consistent in amplitude to ensure the sound effect of the sound generated by the speaker 100. On the other hand, when the drum paper 40 is driven by the voice coil 30, it moves along the vertical axial direction. At this time, the connection between the hanging edge 12 and the drum paper 40 is not easily damaged by pulling each other, thereby ensuring the reliability and stability of the speaker 100 in the event of an accident.

Compared with the circular drum paper of the prior art, the drum paper 40 of the speaker 100 of the present invention is non-circular in shape when viewed from above. For example, according to FIG. 4 , the drum paper 40 is in the shape of a racetrack when viewed from above. According to FIG. 6 , the drum paper 40 is in the shape of an ellipse when viewed from above. Therefore, compared with the circular drum paper of the prior art, the drum paper 40 of the present invention has an effectively increased surface area of the drum paper 40 that stirs the air. It can be understood by those skilled in the art that the increase in the surface area of the drum paper 40 that stirs the air can increase the volume of the speaker 100 by increasing the amount of air stirred by the drum paper 40. That is, compared with the circular speaker 100 of the prior art, the speaker 100 of the present invention of the same specification (e.g., equal or similar power and size) has a higher volume without increasing the power, that is, the present invention improves the efficiency by increasing the amount of air stirred by the drum paper 40. For example, in a specific embodiment of the present invention, the efficiency of the drum paper 40 of the present invention can be increased by 10db, so that the speaker 100 can increase the sound pressure by 3 times.

In addition, the speaker 100 of the present invention does not need to increase the stroke of the drum paper 40, but increases the volume of the drum paper 40 when the drum paper 40 is driven by increasing the area of the drum paper 40, so as to increase the volume of the speaker 100, thereby enabling the speaker 100 to develop in the direction of being lighter and thinner. Compared with the speaker with a circular drum paper in the prior art, when the speaker 100 of the present invention and the speaker in the prior art have the same volume, the distance that the drum paper 40 of the speaker 100 of the present invention is moved is smaller than the distance that the drum paper of the speaker in the prior art is moved, that is, the stroke of the drum paper 40 of the speaker 100 of the present invention is smaller, so as to facilitate the speaker 100 of the present invention to develop in the direction of being lighter and thinner, which is unexpected for the speakers in the prior art, and the method provided by the speaker 100 of the present invention is particularly effective in controlling the size of the speaker 100, especially controlling the thickness of the speaker 100. The voice coil 30 is disposed in the middle of the drum paper 40, so that the driving force of the voice coil 30 on the drum paper 40 can be transmitted from the middle position of the drum paper 40 to the edge position, thereby avoiding the undesirable phenomenon that the drum paper 40 tilts and shakes when the drum paper 40 is driven by the voice coil 30 to move back and forth along the vertical axial direction. For a circular drum paper, the matching position of the voice coil 30 and the drum paper 40 can achieve a good effect, while for the non-circular drum paper 40 of the present invention, such as the racetrack-shaped drum paper and the elliptical drum paper disclosed in Figures 4 and 6 of the present invention, the smooth surface provided by the drum paper 40 makes it easy to deviate and shake when it is driven by the voice coil 30 to move back and forth in the axial vertical direction, and once this situation occurs, it will inevitably have a bad impact on the sound quality of the speaker 100.

In order to overcome this technical defect, the drum paper 40 of the present invention has a first axial direction 401 and a second axial direction 402. The first axial direction 401 and the second axial direction 402 are as shown in Figure 1 respectively. The x-axis direction and the y-axis direction shown in , the extension direction of the first axial direction 401 and the extension direction of the second axial direction 402 are perpendicular to each other, and the drum paper 40 is in the first axial direction 401 The size is larger than the size of the drum paper 40 in the second axial direction 402 . For example, in this embodiment of the present invention, the length dimension of the drum paper 40 in the first axial direction 401 is greater than the length dimension of the drum paper 40 in the second axial direction 402, so that the drum paper 40 forms two drum paper end portions 403 in the first axial direction 401 and two drum paper side portions 404 in the second axial direction 402 . That is to say, the drum paper 40 has two drum paper end portions 403 and two drum paper side portions 404 .

Let the distance dimension parameter between the two drum paper ends 403 of the drum paper 40 be L, and let the distance dimension parameter between the two drum paper side parts 404 of the drum paper be W, where The ratio range of the distance L between the two drum paper ends 403 of the drum paper and the distance W between the two drum paper side parts 404 is L:W greater than or equal to 2:1. In a specific example, the ratio of the distance L between the two drum paper ends 403 of the drum paper 40 and the distance W between the two drum paper side parts 404 is L:W, which is 7:3. In another specific example, the ratio of the distance L between the two drum paper ends 403 of the drum paper 40 and the distance W between the two drum paper side parts 404 is L:W, which is 3:1. .

Those skilled in the art can understand that compared with the circular drum paper of the prior art, the surface area of the drum paper 40 of the present invention for blowing air is effectively increased, so that when the drum paper 40 is When the voice coil 30 is driven, the amount of air that the drum paper 40 can inhale is effectively increased, thereby increasing the volume of the speaker 100 . Therefore, those skilled in the art can understand that the present invention does not increase the volume of the speaker 100 by increasing the stroke of the drum paper 40, but increases the volume of the speaker 100 by increasing the air volume of the drum paper 40 for agitation. In this way, even if the drum paper 40 has a smaller stroke, the volume of the speaker 100 can be guaranteed, so that the thickness of the speaker 100 can be designed to be thinner. To increase the applicable range of the speaker 100 .

The drum paper 40 includes a pair of first parts 43 and a pair of second parts 44 connected to each other, wherein each of the first parts 43 is symmetrically formed in the first axial direction 401 of the drum paper 40, that is, , each first portion 43 is respectively located at each drum paper end 403 of the drum paper 40 , wherein each of the second portions 44 is symmetrically formed on the second end portion 403 of the drum paper 40 . Axial direction 402 , that is, each second portion 44 is located at each drum paper side portion 404 of the drum paper 40 .

Each first portion 43 and each second portion 44 of the drum paper 40 respectively extend from a central position to an edge position of the drum paper 40 , that is, each third portion of the drum paper 40 One portion 43 and each second portion 44 respectively extend from the inner portion 41 of the drum paper 40 to the outer portion 42 of the drum paper 40 , and the first portion 43 extends from the inner portion 41 of the drum paper 40 The distance from the middle position to the edge position of the second portion 44 is greater than the distance from the middle position to the edge position of the drum paper 40 , so that the drum paper 40 forms a non-circular drum paper.

Preferably, each first part 43 and each second part 44 of the drum paper 40 are formed integrally, in this way, the transition of each position in the circumferential direction of the drum paper 40 is uniform, so as to ensure the sound effect of the speaker 100 when it occurs later. At the connection between the first part 43 and the second part 44 of the drum paper 40, the first part 43 and the second part 44 have opposite curvatures, so that a groove or a protrusion is formed at the connection between the first part 43 and the second part 44 of the drum paper 40. For example, in this embodiment of the present invention, the drum paper 40 forms a groove at the connection between the first part 43 and the second part 44 to increase the strength of the drum paper 40. In this way, when the voice coil 30 is acted upon by the magnetic return unit 20 to drive the drum paper 40 to move back and forth along the vertical direction at the inner side 41 of the drum paper 40, the structure of the drum paper 40 enables the driving force generated when the voice coil 30 acts on the inner side 41 of the drum paper 40 to be uniformly transmitted from the inner side 41 to the outer side 42, so that the drum paper 40 will not tilt or shake when moving back and forth in the vertical axial direction, so as to ensure the purity of the sound effect produced by the speaker 100. 5A and 5B , the first portion 43 and the second portion 44 of the drum paper 40 are respectively arched upward.

The drum paper 40 is provided with two pairs of rib elements 45 , and each pair of the rib elements 45 radially extends from the inner portion 41 to the outer portion 42 of the drum paper 40 for blocking the drum paper 40 Tilting and deflection occur while being driven in a vertical axial direction. Specifically, when the drum paper 40 is driven by the voice coil 30 to move along the vertical axial direction, if the drum paper 40 has a tendency to tilt to one side, the ribs provided on that side will The element 45 prevents the drum paper 40 from tilting to this side to ensure that the drum paper 40 can only move in one direction. For example, when the drum paper 40 is driven by the voice coil 30 to move along the vertical axial direction, if the drum paper 40 tends to tilt to the right side of the speaker 100 , the drum paper 40 is disposed on the drum. The rib element 45 on the right side of the paper 40 can prevent the drum paper 40 from tilting to the right side of the speaker 100 . Similarly, if the drum paper 40 tilts to the left side of the speaker 100 trend, the rib element 45 provided on the left side of the drum paper 40 can prevent the drum paper 40 from tilting to the right side of the speaker 100. In this way, the drum paper The displacement direction of the speaker 40 is limited to only move in the vertical axial direction, thereby ensuring the purity of the sound effect of the speaker 100 .

Preferably, each of the rib elements 45 is formed between the first part 43 and the second part 44, respectively, and each of the rib elements 45 is integrally formed with each of the first part 43 and each of the second part 44, so that the driving force generated when the voice coil 30 acts on the drum paper 40 can be evenly transmitted from the inner part 41 to the outer part 42 of the drum paper 40.

Further, the drum paper 40 includes two reinforcing elements 46, wherein each of the reinforcing elements 46 is integrally provided at both ends of the first axial direction 401 of the drum paper 40, that is, each The reinforcing elements 46 are integrally formed on each drum paper end 403. In this way, the reinforcing elements 46 reinforce the ends of the drum paper 40 in the first axial direction 401. The strength of the drum paper 40 is thereby prevented from collapsing at both ends of the first axial direction 401 when the drum paper 40 is driven, thereby ensuring the reliability of the drum paper 40 and improving the speaker 100 sound quality.

The magnetic return unit 20 can generate electromagnetic force to drive the voice coil 30 to drive the drum paper 40 to move up and down, so that the drum paper 40 agitates the air to produce sound. The limiting mechanism 50 is used to limit the movement of the voice coil 30 along the vertical axial direction to prevent the voice coil 30 from deviating. In this way, the sound quality of the speaker 100 can be improved.

In this embodiment of the present invention, the cross-sectional shape of the limiting mechanism 50 may be a "U" shape, so that the limiting mechanism 50 forms a structure similar to the suspension edge 12 . During the operation of the speaker 100 When the voice coil 30 has a tendency to deviate in the vertical axial direction, the hanging edge 12 can prevent the voice coil 30 from deflecting so that the movement of the voice coil 30 remains in the vertical axial direction. The limiting mechanism 50 may be made of a material that is easy to deform and has good toughness. For example, the material forming the limiting mechanism 50 may be rubber.

In one embodiment of the present invention, the limiting mechanism 50 can be independently supported, and then the inner part and the outer part of the limiting mechanism 50 are connected to the voice coil 30 through glue or other similar means. and the support unit 10 .

The thickness of the connecting positions of the supporting unit 10 is greater than the thickness of the limiting mechanism 50 in the middle, so as to ensure the connection relationship between the limiting mechanism 50 and the voice coil 30 and the supporting unit 10 respectively. The deformation ability and recovery ability of the limiting mechanism 50. Referring to Figure 10 to Figure 12,

Each limiting element 53 has elasticity, so that when the voice coil 30 is driven by the magnetic return unit 20, it can drive the inner bracket 51 to move back and forth along the vertical axial direction because the outer bracket 52 is connected. The speaker frame 11 does not move with the movement of the inner bracket 51 , so that the limiting mechanism 50 can limit the voice coil 30 to only move in the vertical axial direction through the outer bracket 20 without moving. Tilting occurs and the stroke of the voice coil 30 is limited by the deformability of each pair of limiting elements 53 . In addition, when the inner bracket 51 is driven by the voice coil 30 and tends to deflect, each pair of the limiting elements 53 is used to prevent the inner bracket 51 from being driven by the voice coil 30 and deflecting. This ensures the purity of the sound effect of the speaker 100 .

Further, each of the limiting elements 53 extends curvedly between the inner bracket 51 and the outer bracket 52 respectively. In this way, the stroke of each of the limiting elements 53 in the vertical axial direction can be increased.
