Abstract

(57) [Abstract] [Purpose] The present invention is intended to provide a hearing aid for facilitating hearing sounds of the hearing impaired and improving daily life. The present invention is directed to a sound collector 1 composed of a single sound collecting plate or a plurality of foldable sound collecting plates and a holder for engaging the sound collector 1 with the head of a user and supporting the sound collector 1 at a position behind the ear. It consists of 2.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a hearing aid used by a hearing-impaired person to facilitate hearing.

[0002]

[Prior art]

 As a simple means for hearing-impaired people to hear sound, there are methods for hearing the sound by holding the palm of the hand over the ear and wearing an electric hearing aid in the ear.

[0003]

[Problems to be solved by the device]

 In the above-mentioned conventional means for hearing-impaired people to hear sound, it is good to just listen to the sound by holding the palm of the hand over the former ear, but in the work using the hand Both cannot be done at the same time, and the latter hearing aid has too good a sensitivity to pick up unwanted sounds, which makes it difficult to sort, fatigue after long use, or unusable if the battery is exhausted or malfunctions. There are inconveniences such as. In view of the above, the present invention intends to provide a hearing aid which enables both hands to use the hearing sound and which can be easily worn by a hearing-impaired person without causing a failure and having a good hearing sound.

[0004]

[Means for Solving the Problems]

 In order to solve the above problems, the present invention comprises a sound collector 1 and a holder 2 that engages with the head and supports the sound collector 1 at a position behind the ear. In addition to being able to adjust the size of the gathering area, it is possible to adjust the degree of shielding the sound from the back of the ear and the sound from the back and sides of the ear.

[0005]

[Action]

 The hearing aid of the present invention is used by a hearing-impaired person for conversation and the like, and facilitates hearing sound. The sound collector 1 provided on the holder 2 by engaging the holder 2 with the head or the like is placed behind the ear. In addition to being localized, the directivity of the sound collector 1 in the listening direction is adjusted, and noise from the back and sides of the ear is blocked to make it easier to hear the target sound. Since the sound body 1 has an adjustable sound collection area, a small area is required for listening to a nearby sound or a relatively large sound, and conversely, a distant sound or a small sound has a large sound collecting area and a pleasant sound is heard. be able to. In addition, since the sound collector 1 can also adjust the degree of shielding of the ears, the sound heard in a noisy environment is shielded behind and behind the ears so that the noise is less likely to enter the ears and there is no error. Therefore, when trying to listen in a wide range in a quiet atmosphere, the sound collecting body 1 can be adjusted so that the shielding area of the sound collecting body 1 is reduced and the sound can be heard in a wide range. Of course, this hearing aid can be used by people other than the above-mentioned hearing-impaired people. For example, when birdwatching is used when listening to the voice of a bird, the hearing of the bird can be heard clearly. Is. In the hearing aid of the present invention, both hands can be used for other work because the holder 2 is supported by being engaged with the head.

[0006]

【Example】

 An embodiment of the hearing aid of the present invention comprises a metal band or a plastic band having elasticity, and the left and right end portions of the arch-shaped holding body 2 which can be freely expanded and contracted so that the degree of engagement with the head can be adjusted. The sound collector 1 formed of a parabolic reflector made of metal or plastic with good sound reflection was installed so that when the hearing aid was worn on the head, it would face the front of the face behind the ears. It is a thing. The holder 2 has an arched shape as described above in the embodiment. However, this is not limited to the embodiment. In short, the sound collector 1 of the holder 2 is localized at the rear position of the ear and the sound collecting effect is obtained. The shape of the sound collector 1 is not limited to that of the embodiment as long as it has a sound collecting effect.

[0007] The sound collecting body 1 of the invention is to split the current tone plates of parabolic vertically in the embodiment, and fixed to the holder 2 the sound collecting plate 1 ₁ piece side, leaving the other sound collection plate 1 ₂ superimposed on the sound collecting plate 1 ₁ and the upper and lower end portions of the two sound collecting plate 1 ₁ and 1 ₂ and fastened by a pin 3, as rotatable collected plate 1 ₂ to pickup plate 1 ₁ It is installed to adjust the degree of sound collection of the sound collector 1 by adjusting the degree of overlapping of the sound collector 1 _{2 with} the sound collector 1 ₁ so that optimum sound can be heard under any circumstances. However, the number of the sound collectors 1 and the means for adjusting the sound collecting area are not limited to those in the embodiment, and any means can be used as long as the sound collecting area can be adjusted to improve the sound collecting effect and shield from ear noises. Yes.

[0008]

[Effect of device]

 According to the first aspect of the present invention, since the hearing aid has the holder engaged with the head, the engagement with the head is accurate and reliable, and the hearing aid does not come off from the head. Since it is supported by the head, the hand can be used for other purposes, and the sound collector 1 is accurately localized behind the ears to improve the sound collection effect and provide accurate and sensitive sound. In addition to being able to do so, there is an effect that a battery is required unlike the conventional electric hearing aid, no trouble occurs in the hearing aid, it is easy to handle, and it can be provided at a low cost.

According to the second aspect of the present invention, since the sound collecting body 1 can adjust the sound collecting area, the amount of sound collecting can be adjusted depending on the situation in which the sound is picked up, and the best sound can always be heard. .

According to the third aspect of the present invention, the sound collector 1 is capable of adjusting the sound collecting area, thereby adjusting the amount of sound to be collected and always providing the best sound. Since the back and side of the ear can be shielded, the ear can be shielded from unnecessary noise, and a better and clearer hearing sound can be obtained.
