Description

Intelligent Terminal

technical field

The present invention relates to the technical field of mobile communication, in particular to an intelligent terminal.

Background technique

At present, with the popularity of smart terminals such as tablets, mobile phones, and smart watches, more and more attention has been paid to the three-proof (dustproof, waterproof, and drop-proof) performance of smart terminals. Among them, the waterproof performance of smart terminals has always been one of the focuses of manufacturers and users.

At present, smart terminals on the market usually solve the problems of waterproofing and sound transmission of terminal products by affixing a layer of waterproof and sound-permeable film on the shell of the smart terminal. However, the current practice is usually to use double-sided tape to directly attach the waterproof and sound-permeable membrane to the side wall of the shell. Since the thickness of the waterproof and sound-permeable membrane itself is relatively thin and there is no additional protective support structure, it is only suitable for relatively shallow Waterproof in water. However, when the terminal product is located in deep water and subjected to high water pressure, the waterproof and sound-permeable membrane will be deformed after being subjected to the water pressure, which will cause distortion when the terminal product uses the waterproof and sound-permeable membrane for sound transmission. Poor experience; in addition, when the terminal product is placed in deep water and subjected to strong water pressure, the waterproof and sound-permeable membrane will even be severely deformed. The back glue of the sound-permeable membrane may also be peeled off by water pressure, causing waterproof failure.

The circuit board 14 is fixedly connected to support and fix the microphone 15 .

In the above manner, the waterproof sound-permeable membrane 12 is pasted on the side wall of the housing 11 corresponding to the sound pickup hole 11a. While the sound transmission can be realized through the waterproof sound-permeable membrane 12, it can also prevent external water from entering the sound pickup. The hole 11a makes the smart terminal 10 waterproof. At the same time, the fixing plate 13 is pasted on the waterproof sound-permeable membrane 12, and the fixing plate 13 can be used to strengthen the waterproof sound-permeable membrane 12, preventing the waterproof sound-permeable membrane 12 from being seriously deformed under the action of relatively large water pressure. situation, to ensure the waterproof and sound-permeable performance of the waterproof sound-permeable membrane 12. In addition, there is a gap between the fixing plate 13 and the waterproof sound-permeable membrane 12, which can ensure that the waterproof sound-permeable membrane 12 has a sufficient effective deformation range, thereby ensuring its normal sound transmission.

Please refer to FIG. 2 to FIG. 5 together. In this embodiment, the smart terminal 10 can be a mobile phone, a tablet computer, or a smart watch. Taking a smart watch as an example, the casing 11 can be the shell of the smart watch, and the sound pickup hole 11a can be a through hole provided on the shell of the smart watch.

In this embodiment, the waterproof sound-permeable membrane 12 is a very thin membrane, and its thickness is generally 0.01mm. The waterproof and sound-permeable membrane 12 is generally made of polymer materials, such as polytetrafluoroethylene, etc., and is provided with air-permeable micropores (not shown in the figure), which have the effect of waterproof and air-permeable. Because the pores on the surface of the waterproof sound-permeable membrane 12 are very small, in the state of water vapor, the water particles are very small, and under capillary action, the tiny particles of water can smoothly penetrate into the other side of the capillary, thereby causing vapor transmission. When the water vapor condenses into water droplets, the particles become larger. Due to the surface tension of the water droplets (the water molecules "pull and compete" with each other), the water molecules cannot smoothly separate from the water droplets and penetrate to the other side, thereby waterproofing Effect. The waterproof and sound-permeable membrane 12 is generally thin in film thickness. When the waterproof and sound-permeable membrane 12 is attached to the sound pickup hole 11a of the casing 11, a film layer can be formed in the sound pickup hole 11a of the casing 11, thereby realizing the sound pickup. Waterproofing of the sound hole 11a.

In other embodiments, the waterproof and sound-permeable membrane 12 can also be made of high-strength waterproof mesh. The waterproof mesh has the advantages of good air permeability and good structural strength. When foreign matter enters the sound pickup hole 11a, the high-strength structure of the waterproof mesh can avoid damage to the waterproof sound-permeable membrane 12 caused by foreign matter.

In this embodiment, the waterproof and sound-permeable membrane 12 is attached to the inside of the housing 11, that is, one side of the waterproof and sound-permeable membrane 12 is attached to the inner wall 11b of the housing 11 corresponding to the sound pickup hole 11a. And the central position of the waterproof sound-permeable membrane 12 is set corresponding to the sound pickup hole 11a. That is, the waterproof and sound-permeable membrane 12 is attached to the inside of the housing 11. When the sound from the outside is transmitted into the housing 11 through the sound pickup hole 11a, it first passes through the waterproof and sound-permeable membrane 12, and then passes through the waterproof and sound-permeable membrane 12. The vibration transmits the sound to the microphone 15 located inside the casing 11 , thereby realizing the sound transmission.

Further, in order to facilitate the attachment of the waterproof sound-permeable membrane 12, an attachment area 11c is provided on the inner side wall 11b of the housing 11, and the attachment area 11c is a recessed area provided on the inner side wall 11b of the housing 11 , the waterproof sound-permeable membrane 12 is pasted in the pasting area 11c. By setting the sticking area 11c as a recessed area on the inner wall 11 of the casing 11, the positioning and sticking of the waterproof sound-permeable membrane 12 can be realized, and the waterproof sound-permeable membrane 12 can be completely attached when sticking. Lay flatly in the pasting area 11c to prevent the waterproof and sound-permeable membrane 12 from wrinkling during the pasting process. Specifically, the sound pickup hole 11a is connected to the attached area 11c, and the central position of the waterproof sound-permeable membrane 12 is facing the sound pickup hole 11a, so as to prevent external water from entering the housing 11 from the sound pickup hole 11a. . Preferably, one side of the waterproof sound-permeable membrane 12 is attached to the attachment area 11c of the casing 11 through an adhesive 121, and the adhesive 121 is preferably a waterproof double-sided tape, so that the waterproof sound-permeable membrane 12 is pasted on the attached area 11c, the waterproof performance of the waterproof sound-permeable membrane 12 can also be enhanced to prevent water from infiltrating from the connection between the waterproof sound-permeable membrane 12 and the attached area 11c.

Further, since the thickness of the waterproof and sound-permeable membrane 12 is relatively thin, in order to strengthen the strength of the waterproof and sound-permeable membrane 12 and facilitate the sticking of the waterproof and sound-permeable membrane 12, a reinforcement layer is pasted on the other side of the waterproof and sound-permeable membrane 12. 12a, and the central position of the reinforcement layer 12a corresponding to the waterproof sound-permeable membrane 12 is provided with an escape groove (not marked in the figure), that is, the reinforcement layer 12a is provided with the avoidance groove at the position corresponding to the sound pickup hole 11a To avoid affecting the sound transmission performance of the waterproof sound-permeable membrane 12, and ensure that the waterproof sound-permeable membrane 12 can vibrate normally to transmit sound. Specifically, the reinforcing layer 12a is pasted on the other side of the waterproof sound-permeable membrane 12 through a double-sided adhesive tape 122, and before the waterproof sound-permeable membrane 12 is pasted on the inner wall 11b of the housing 11, the reinforcing layer The layer 12a has been pasted on the waterproof and sound-permeable membrane 12, so that the waterproof and sound-permeable membrane 12 is not easy to wrinkle when it is pasted. Preferably, the reinforcing layer 12a is made of polyethylene terephthalate (PET).

In this embodiment, the fixing plate 13 is attached to the other side of the waterproof and sound-permeable membrane 12, that is, when the waterproof and sound-permeable membrane 12 is attached to the attachment area of the housing 11 11c, the fixed plate 13 is also located in the attached area 11c, and the fixed plate 13 is attached to the reinforcing layer 12a of the waterproof sound-permeable membrane 12, so that there is no gap between the fixed plate 13 and the waterproof sound-permeable membrane 12. Direct contact, that is, there is a seam connection between the fixing plate 13 and the waterproof sound-permeable membrane 12, so as to prevent the fixing plate 13 from squeezing the waterproof sound-permeable membrane 12 and affecting the performance of the waterproof sound-permeable membrane 12 in vibrating and transmitting sound.

Wherein, in order to ensure that the waterproof and sound-permeable membrane 12 does not produce distortion when transmitting sound, the gap between the fixing plate 13 and the waterproof and sound-permeable membrane 12 is within the effective deformation range of the waterproof and sound-permeable membrane 12, that is to say , the gap between the fixing plate 13 and the waterproof and sound-permeable membrane 12 is equal to the effective deformation of the waterproof and sound-permeable membrane 12 . Specifically, the gap between the fixing plate 13 and the waterproof sound-permeable membrane 12 can be set to (0.1-0.2) mm. That is, the gap between the fixing plate 13 and the waterproof sound-permeable membrane 12 can be set to 0.1 mm, 0.15 mm or 0.2 mm, etc.

The design of the gap value between the fixed plate 13 and the waterproof and sound-permeable membrane 12 is adopted to ensure that the waterproof and sound-permeable membrane 12 has a sufficient effective deformation range to ensure that it can normally vibrate and transmit sound, and avoid the gap between the fixed plate 13 and the waterproof and sound-permeable membrane. If the gap between the membranes 12 is too small, the waterproof and sound-permeable membrane 12 cannot be effectively deformed and cannot vibrate and transmit sound normally; 12 cases where the waterproof performance drops.

Further, since during installation, the fixing plate 13 is directly attached to the reinforcement layer 12a of the waterproof sound-permeable membrane 12, that is, the reinforcement layer 12a and the double-sided adhesive tape 122 on the reinforcement layer 12a make the fixing There is the above-mentioned gap between the board 13 and the waterproof sound-permeable membrane 12 . That is to say, the gap between the fixing plate 13 and the waterproof sound-permeable membrane 12 is equal to the sum of the thickness of the reinforcement layer 12a and the thickness of the double-sided adhesive tape 122 on the reinforcement layer 12a.
