Description
【０００１】
（発明の届する技術分野）
本発明は、耳殻に沿って支持され、前方に向けられた楕円形の曲面を有する集音板と、その内側に設けられた反射板を備えた補聴器に於て、内側の反射板に、回折孔を設けて、外側集音板の集音効果と、明瞭度を高めるものである。
【０００２】
（従来の技術）
従来の耳かけ集音器を備えた補聴器は、単に４等分された球体を、外耳部に装着する、例えば（実開平６−１９４００）か又は、２重の集音部を備えて利得を高めようとするものであった。例えば（特解２０００−３５８３００）
【０００３】
（発明が解決しようとする課題）
本発明は、上記の２重の集音部を備えた補聴器について、その音の利得と、明瞭性を高めるものである。
【０００４】
（課題を解決するための手段）
上記目的を達成するために、本発明の補聴器に於ては、耳殻を被う２重になった集音板と反射板のうち、内側の反射板に、回折の為の小孔を設け、外側の集音板に集められた音を、効果よく耳道に至らしめるものである。
【０００５】
上記の回折孔の位置は、内側の反射板の外耳道に面した位置に限定し、その数も少くして、反射板の有効面積をあまり減少させぬ様にする。
【０００６】
回折孔の大きさは、外側の集音板によって集められた音を、有効に外耳に到達し且つ乱反射による干渉を少くする為、適度のものとする。
【０００７】
上記の目的から、回折孔の大きさは、数ミリメートル、個数は数個とする事が好ましい。
【０００８】
（発明実施の形態）
発明実施の形熊を実施例にもとづき図面を参照して説明する。
図１は本発明の回折孔（４）を設けた反射板（３）を有する補聴器の右耳用を内側から見た斜視図である。（１）は耳殻に引掛ける支持板。（２）は外側の集音板、（３）は（２）の集音板の内側に設けられた反射板である。以上は（特解２０００−３５８３００）の補聴器の概要であるが、本発明では、反射板（３）の耳道に面した部分に、直径数ミリメートルの回折孔（４）を数個設けて、更に音圧と音質を高めようとするものである。
【０００９】
（発明の効果）
本発明は、以上説明したように構成されているので、２重の集音部を有する補聴器の利得と明瞭度を、著しく向上するものである。

(Technical field to which the invention reaches)
The present invention provides a hearing aid including a sound collecting plate supported along the ear shell and having an elliptical curved surface directed forward, and a reflection plate provided on the inside thereof. A diffraction hole is provided to enhance the sound collection effect and clarity of the outer sound collection plate.
[0002]
(Conventional technology)
A hearing aid equipped with a conventional ear-collecting sound collector simply attaches a sphere that has been divided into four equal parts to the outer ear, for example (Japanese Utility Model Laid-Open No. Hei 6-19400), or has a double sound collecting section to provide a gain. It was something to be raised. For example (Special Solution 2000-358300)
[0003]
(Problems to be solved by the invention)
The present invention improves the sound gain and clarity of the hearing aid provided with the above-described double sound collection unit.
[0004]
(Means for solving the problem)
In order to achieve the above object, in the hearing aid of the present invention, a small hole for diffraction is provided in the inner reflecting plate of the double sound collecting plate and the reflecting plate covering the ear shell. The sound collected on the outer sound collecting plate is effectively brought to the ear canal.
[0005]
The position of the diffractive hole is limited to a position facing the external auditory canal of the inner reflector, and the number thereof is reduced so that the effective area of the reflector is not reduced so much.
[0006]
The size of the diffractive hole is appropriate for the sound collected by the outer sound collecting plate to reach the outer ear effectively and reduce interference due to diffuse reflection.
[0007]
For the above purpose, it is preferable that the size of the diffraction holes is several millimeters and the number is several.
[0008]
(Embodiment)
An embodiment of the invention will be described with reference to the drawings based on the embodiments.
FIG. 1 is a perspective view of a hearing aid having a reflector (3) provided with a diffraction hole (4) according to the present invention as viewed from the right ear. (1) is a support plate to be hooked on the ear shell. (2) is an outer sound collecting plate, and (3) is a reflecting plate provided inside the sound collecting plate of (2). The above is the outline of the hearing aid of (Special Solution 2000-358300), but in the present invention, several diffraction holes (4) having a diameter of several millimeters are provided in the part facing the ear canal of the reflector (3), Furthermore, it is intended to increase sound pressure and sound quality.
[0009]
(The invention's effect)
Since the present invention is configured as described above, it greatly improves the gain and clarity of a hearing aid having a double sound collection unit.
[Brief description of the drawings]
It is the top view which looked at the object for right ears of the hearing aid provided with the reflecting plate which provided the figure folding hole from the inner side.
