Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a sound transducer, particularly an ear-hook type sound transducer which is convenient to carry.

Various kinds of ear-hook type acoustic transducers have been proposed in the past, and FIG. 1 is an example of such devices.
That is, in FIG. 1, 1 is an acoustic transducer such as a speaker, 2 is an ear hook member mounted on the speaker 1, 3 is a lead wire, and 4 is a plug. The ear hook member 2 is generally made of, for example, hard synthetic resin, and is of a so-called rigid type that is not easily deformed.

By the way, the size and contour of human ears vary from person to person, and Figures 2 to 4 show the data for each point when ear size is segmented around the external auditory canal for 12 men and 12 men. This shows an example of measurements taken. That is, Fig. 2 A and B
, 5 is the external auditory canal, 6 is the auricle, 7 is the helix of the ear, and 8
9 schematically shows the earlobe, 9 the concha cavity, 10 the side surface of the head, and 11 the back side of the auricle 6 that substantially corresponds to the concha cavity 9. The base of the front side 11 is the external auditory canal 5. It is in contact with the side surface 10 of the head with a certain diameter (represented by the symbol h in FIG. 2A) around the center.

Then, as shown in Fig. 2, a
When the test was divided into ~k segments and measured on, for example, 12 men and 12 men, data as shown in Figures 3 and 4 were obtained, respectively. In Figures 3 and 4,
The upper row of each segment a to k shows data for the right ear, and the lower row shows data for the left ear. From Figures 3 and 4, it can be seen that men's ears are generally larger than women's ears, and there is also a slight difference in size between the right and left ears of the same person.

In this way, there are individual differences in the size of human ears, but in the case of the conventional device shown in Figure 1,
Since the ear hook member 2 is of a rigid type that is difficult to deform, it cannot be adjusted according to the size and contour of the ear, and the sound emitting part of the speaker 1 cannot be properly matched to the ear canal 5 to obtain an appropriate sense of volume. It was hot.

Further, if the sound emitting part of the speaker 1 is forced to correspond to the ear canal 5, there are drawbacks such as giving a feeling of fatigue to the ears and also making it troublesome to wear the speaker.

In view of these points, the present invention has been developed to allow the device to be properly and easily attached to the ear according to the size and contour of the ear, to provide excellent wearing comfort and operability, and to allow for arbitrary pressure (fit feeling). The present invention provides an ear-hook type acoustic transducer.

Embodiments of the present invention will be described in detail below with reference to FIGS. 5 to 7.

FIG. 5 shows a first embodiment of the present invention. In FIG. 5, an ear hook member 2 having a substantially arc shape is shown.
1 and 22 are provided, and these ear hook members 21 and 22 are provided.
The ends of each of the ear hook members 21 and 22 are connected by a shaft 23, and an elastic member (not shown), such as a spring, is installed inside the shaft 23, so that the ear hook members 21 and 22 are connected in the direction indicated by the arrow.
In other words, it can be rotated in the direction in which it is worn along the back side 11 of the auricle 6 (FIG. 2B). The diameter formed by the back side part 11 in contact with the side surface 10 of the head is, for example, represented by h in FIGS. 21 and 22 can be rotated arbitrarily to accommodate this variation in diameter. In addition,
The ear hook member 22 is made longer and thicker than the ear hook member 21 to obtain stability.

Further, 24 is an acoustic transducer such as a speaker, 25
is a lead wire electrically connected to the speaker 24,
A plug 26 is connected to one end of the lead wire 25, and the speaker 24 is connected to the other end of the ear hook member 21 by a flexible connecting member 27 such as a wire. By using a flexible connecting member 27, the speaker 24 can be positioned independently of the positions of the ear hook members 21 and 22.
In other words, since the conventional device shown in FIG. 1 is of a rigid type, the position of the speaker 1 is automatically determined at the same time as the ear hook member 2 is attached to the ear, and the positional deviation with respect to the external auditory canal 5 can be substantially adjusted. Although it is possible to lower the ear hook members 21 and 22 in this embodiment,
Due to the action of the flexible connecting member 27, the ear hook members 21 and 22 are first attached to the ear by holding the back side 11 of the auricle 6 in their mouths, and when the connecting member 27 is properly attached, the connecting member 27 is removed. It is possible to adjust the positional deviation of the speaker 24 with respect to the external auditory canal 5 while bending, and to properly align the speaker 24 with the external auditory canal 5 to obtain an appropriate sense of volume.

FIG. 6 shows a second embodiment of the present invention, in which parts corresponding to those in FIG. 5 are designated by the same reference numerals, and detailed explanation thereof will be omitted.

In this embodiment, two arc-shaped ear hook members 28 and 29 having different lengths are used, as in FIG. 29 is attached with a shaft 23 so that it can be rotated in the direction shown by the arrow. Of course, a spring may be interposed at the shaft 23 in this case as well. Therefore, when worn, the ear hook member 28 is substantially hung on the back side 11 of the auricle 6, and the ear hook member 29 is shaped to hold the ear lobe 8 in its mouth. In other words, the ear hook member 29
As can be seen from Figures 3 and 4 above, the maximum value of segment c is 50 compared to the minimum value of 33.
Since it varies within the range of , it acts as a correction for that.

When worn, the ear hook member 28 is hung on the back side 11 of the auricle 6, the auricle 6 is held between the ear hook member 28 and the connecting member 27, and the ear hook member 29 is further rotated counterclockwise. Move your earlobes 8
Hold the part in your mouth.

Therefore, in this embodiment, the same effects as in the first embodiment can be obtained, and furthermore, in this embodiment, the ear hook member 2
9 makes it possible to securely attach the earphone to the ear, which is extremely useful especially when the earphone is used for intense movements such as sports.

FIG. 7 shows a third embodiment of the present invention, in which parts corresponding to those in FIGS. 5 and 6 are denoted by the same reference numerals, and detailed explanation thereof will be omitted.

In this embodiment, arc-shaped ear hook members 30 and 31 of substantially the same size are connected via a shaft 23, and both members are rotated in the direction of the arrow by an elastic member (not shown). With such a configuration, the ear hook members 30 and 31 are approximately evenly attached to the back side 11 of the auricle 6.
Therefore, even if the shape of the back side portion 11 is slightly different, it can be mounted in a manner that corresponds to the shape.

Therefore, this embodiment can also provide substantially the same effects as those of the first and second embodiments.

As described above, according to the present invention, a plurality of ear-hook members are used and are configured to be rotatably connected so that the centers of their arcs are different, so that by changing the curves formed by the plurality of ear-hook members, , it is possible to obtain an ear-hook type sound transducer that can adjust the mounting position of the device to accommodate ears of any shape, has excellent wearing comfort, operability, etc., and has less fatigue, discomfort, etc. . In addition, since the acoustic converting member is supported by an ear hook member made of a plurality of rotatably connected members and a flexible connecting member, it is possible to adjust the position of the ear depending on the individual. The connecting member can be adjusted to fit the dimensions and flex to suit the preferences and required crimping force of each individual using the connecting member, and the acoustic transducer can be opposed to the ear canal; Good playback sound can be obtained.

In addition, although the above-mentioned embodiment explained the case where two ear-hook members are connected, it is also possible to have a structure in which more ear-hook members are connected, and by increasing the number, the shape of the ear-hook part can be more closely approximated. A curve will be obtained.

Further, although the case where a spring is used as the method for rotating the plurality of ear hook members has been described, other methods may be used as long as the same function can be achieved.
