Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a hearing aid having an insertion portion to be inserted into the outer ear of a user.

[0002]

[Prior Art]

 The appearance of a conventional hearing aid is shown in FIG. As is clear from this figure, the hearing aid is composed of a main body portion 61 and an insertion portion (ear tip) 62 that is inserted into the ear canal of the user. Usually, these are integrally molded with hard resin. ing.

[0003]

[Problems to be solved by the device]

 As described above, the conventional ear tip 62 projects from the body portion 61 at a constant angle. Generally, the ear canal of a person has a complicated shape represented by a complicated cubic curve, and the shape of the ear canal is different from person to person, which causes pain when the ear tip of the hearing aid is loaded. In some cases, it was difficult to load. Before inserting the ear canal, there is a device that fits to the ear canal by rotating the insertion part.However, it is necessary to insert the ear canal into the ear canal every time it is adjusted and check the adjustment condition. It was very troublesome. In order to eliminate such a problem, a custom-made hearing aid that creates an ear tip that matches the shape of the user's outer ear is commercially available, but such a hearing aid was not popular because of its high price. .

The present invention has been made in view of the above-described conventional example, and an object thereof is to provide a hearing aid that can be worn according to the outer ear shape of the user by changing the angle of the insertion portion with respect to the hearing aid body. To do.

[0005]

[Means for Solving the Problems] and

[Action]

 In order to achieve the above object, the hearing aid of the present invention has the following configuration. That is, a hearing aid having an insertion portion that is inserted into the ear canal of the user, and supporting the insertion portion against the body of the hearing aid so that the insertion portion can be freely rotated by the pressure applied to the insertion portion when the ear canal is inserted. .

According to another invention, the hearing aid body and the insertion portion are connected via an elastic body.

According to still another aspect, the hearing aid body side of the insertion part is formed in a spherical shape, and the hearing aid body includes a receiving part for receiving a spherical member, and the insertion part is pivotally supported with respect to the hearing aid body. Has been done.

According to another invention, the hearing aid main body and the insertion portion are connected via a laminated member.

According to another invention, the hearing aid body and the insertion portion are connected via a spring.

【Example】

 Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is an external perspective view of the hearing aid of this embodiment, and FIG. 2 is a sectional view taken along the line AA of FIG.

1 and 2, reference numeral 101 denotes a body case of a hearing aid, and 102 denotes an insertion portion (ear tip) that is inserted into the ear canal of the user. The ear tip 102 is made of, for example, ABS resin. Reference numeral 103 denotes a movable part, which is molded of a soft resin such as polyurethane. In the hearing aid of this embodiment, the ear tip 102 and the movable part 103 are manufactured by two-color molding, but they may be manufactured in separate processes and the parts may be bonded to each other.

As shown in FIG. 2, a receiver 21 is built in the ear chip 102, and is connected to a circuit board built in the main body case 101 by a lead wire 22. Reference numeral 24 is a battery, a sound collecting microphone, or the like.

With such a configuration, the ear tip 102 can be swung with respect to the main body case 101. Thus, even if there is a difference in the shape and angle of the ear canal for each individual, the angle of the ear tip 102 with respect to the main body case 101 can be deformed along the ear canal, so that a hearing aid suitable for that person can be provided.

FIG. 3 is a sectional view showing a schematic configuration of a hearing aid according to a second embodiment of the present invention. In the drawings thereafter, the same parts as those in FIG. 2 described above will be denoted by the same reference numerals, and the description thereof will be omitted.

Reference numeral 31 denotes an ear tip, and 32 denotes a main body case, and a joint portion 33 of the ear tip 31 with the main body case 32 is spherical. Corresponding to this, the main body case 32 side is provided with a concave portion 34 for receiving the spherical portion, and the ear tip 31 is pivotally supported with respect to the main body case 32.

FIG. 4 is a cross-sectional view showing still another embodiment of the present invention, in which the ear tip 41 and the body case 42 are connected by a laminated member 43, whereby the ear case 41 and the body case 42 are connected to each other. The angle of the tip 41 can be freely changed.

Further, FIG. 5 is a sectional view showing the shape of a hearing aid of another embodiment, in which the ear tip 51 and the main body case 52 are connected by a spring 53. As a result, the angle of the ear tip 51 with respect to the body case 52 can be freely changed, as in the case of the hearing aids of the other embodiments described above.

As described above, according to the hearing aid of the present embodiment, since the ear tip can be swung in the entire circumferential direction with respect to the main body case, even the ear canal that varies from individual to individual suffers. Can be easily inserted without giving. Further, since the hearing aid having such a structure is cheaper than the hearing aid made according to the shape of the ear canal of each individual, the economical burden can be reduced.

[0020]

[Effect of the device]

 As described above, according to the present invention, the angle of the insertion part with respect to the body of the hearing aid can be changed at the time of insertion so that the hearing aid can be worn according to the outer ear shape of the user, so that the user can wear it without any pain or discomfort. There is an effect that can be.
