JPH0619400U - Sound collection hearing aid - Google Patents

Abstract

(57) [Summary] (Modified) [Purpose] The present invention is a hearing aid used by a person with average hearing ability to enhance hearing, unlike hearing aids used by general hearing impaired persons. The application is different from that of a hearing aid that has a sound amplification circuit. In my daily life, I was surprised to hear better sound, but I couldn't find a simple device to meet the demand. The present invention addresses this problem, and by devising the material of the reflection sound collecting plate, it is possible to collect the fidelity sound over the entire sound range or selectively collect the specific sound range. [Structure] In order to efficiently collect the sound coming from the front of the face, a concave reflective sound collecting plate like the inner surface of a quadrant, which is a half-sphere divided into two, is attached along the outer ear part. It collects the sound coming from the front, raises the sound pressure level, and sends it to the inner ear to enhance hearing. In addition, since there is a difference between the sound pressure level of the front collected sound and the sound pressure level of the side and the back where the sound collection effect cannot be obtained, SN
Since the ratio (signal-to-noise ratio) is improved and the clarity of the sound in front is increased, the effect of hearing aid is further obtained.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a hearing aid that enhances hearing by increasing the sound pressure level entering the inner ear by collecting sound using a concave reflective sound collecting plate in the outer ear portion.

[0002]

[Prior art]

 Conventional hearing aids convert sound into an electric signal, amplify it, and use a diaphragm to send the expanded sound to the inner ear.However, it is intended for hearing aids for the hearing impaired, and a general hearing aid like the present invention is used. It was not used by people with hearing levels to assist in hearing.

[0003]

[Problems to be solved by the device]

 When listening to music, etc. in a concert hall or a stereo playback device, the sound of the stage may be too hard to hear at a position behind the venue, or the stereo sound may be loud and you may want to enjoy it, but a loud sound may be produced under ambient conditions. When it was not available, it was difficult to deal with the conventional technology. The present invention was devised to solve these problems.

[0004]

[Means for solving the problem]

 "A hearing aid that uses a concave reflective sound collecting plate, such as the inner surface of a quadrant that is divided by a line that divides a hemisphere, along the outer ear."

[0005]

[Action]

 The human outer ear originally has a certain level of sound collecting function, but in order to make it more efficient, the present invention seems to divide the hemispherical reflection sound collecting plate used in the sound collecting microphone into two equal parts. By attaching a concave reflective sound collecting plate along the outer ear part and collecting a wide range of sound waves to raise the sound pressure level, it is possible to enhance the hearing ability. In addition, since the sound collection function is directional at the same time, the sound pressure levels on the left, right, and rear of the outer ear to which this device is attached are relatively reduced, improving the clarity of the sound and making it easier to hear the sound in front. Become.

[0006]

【Example】

 Hereinafter, examples of the present invention will be described. (B) Attach the reflection sound collectors (1) and (2) to the fixing headband (3). (B) The headband (3) has a structure that can be expanded and contracted so that the position of the reflection sound collection plate can be aligned with the outer ear of the user. (C) Use by attaching it to the outer ear so that the concave surface of the reflection sound collector faces the front of the face. (D) The shape material of the reflection sound collecting plate may be a material that reflects sound with a concave structure capable of collecting sound. This proposal has the structure as described above.When using it, attach it to the left and right outer ears so that the concave surface of the reflection sound collector faces the front of the face, as when using stereo headphones. To do.

[0007]

[Effect of device]

 When this device is set on the outer ear part, the sound coming from the front of the face is collected by the reflection sound collection plate and the sound pressure level inside the outer ear becomes high. The sound can be heard well even when the volume is low in the place, and at the same time, the directivity of the sound is improved, so unnecessary ambient noise is reduced and the clarity of the sound is increased. With a stereo playback device or TV sound, you can enjoy a sound that is sufficiently realistic even at a relatively low volume.
