Description
【考案の詳細な説明】
本考案は耳かけ型の補聴器に関するもので、風防効果を
改善することを目的とする。[Detailed description of the invention] The present invention relates to a behind-the-ear type hearing aid, and its purpose is to improve the windshield effect.
従来この種の補聴器、たとえば第１図のようにハンガー
１の上部に１．４φ程度の音孔２を設けることが、他の
部分に設けたもの比べ良いとされている。Conventionally, in this type of hearing aid, for example, as shown in FIG. 1, it is considered better to provide a sound hole 2 of approximately 1.4φ in the upper part of the hanger 1 than to provide it in other parts.
しかしハンガー１の上部に音孔２を設けた場合風の影響
を受けやすく、これにともなう音響変換出力がイヤホー
ン３より補聴器使用者に伝達さ巨てしまう欠点がある。However, when the sound hole 2 is provided in the upper part of the hanger 1, the sound hole 2 is easily affected by the wind, and the resulting acoustic conversion output is transmitted to the hearing aid user rather than the earphone 3, which has the drawback of being susceptible to wind effects.
本考案はこのような欠点を除去したもので以下第２図の
一実施例により説明する。The present invention eliminates these drawbacks and will be described below with reference to an embodiment shown in FIG.
同図において１１は第１図の１に相当するハンガー、１
２は第１ケース１２１、第２ケース１２２とからなる補
聴器ケース、１３はハンガー１１の上部であって、第１
、第２ケース１２１．１２２の接合面に設けた球状の突
部であって、その突部１３に第３図のように音道１５に
通ずる円形の音孔１４を設けている。In the same figure, 11 is a hanger corresponding to 1 in FIG.
2 is a hearing aid case consisting of a first case 121 and a second case 122; 13 is an upper part of the hanger 11;
, is a spherical protrusion provided on the joint surface of the second case 121, 122, and the protrusion 13 is provided with a circular sound hole 14 communicating with the sound path 15 as shown in FIG.
なおこの音孔１４は第４図、第５図に示すようにスリッ
ト１４′形状としてもよい。Note that the sound hole 14 may have a slit 14' shape as shown in FIGS. 4 and 5.
すなわち本実施例において外部と音道１５とを結ぶ音道
１５の入口に球状の突部１３を設け、その突部１３によ
って音道１５へ加わる風の量を減少させたものである。That is, in this embodiment, a spherical projection 13 is provided at the entrance of the sound path 15 that connects the outside and the sound path 15, and the amount of wind applied to the sound path 15 is reduced by the projection 13.
したがって風防効果を良くすることができる。Therefore, the windshield effect can be improved.
また突部１３、音孔１４あるいはスリット１４′は第１
１第２ケース１２１゜１２２の接合面に設けているため
に同ケースを成形図に同時成形でき、製造が容易である
。Further, the protrusion 13, the sound hole 14 or the slit 14' is the first
Since it is provided on the joint surfaces of the first and second cases 121 and 122, the cases can be molded simultaneously to the molding drawing, making manufacturing easy.
この場合突部１３、音孔１４あるいはスリット１４′は
第１１第２ケース１２１，１２２の一方で形成するよう
にしてもよい。In this case, the protrusion 13, the sound hole 14, or the slit 14' may be formed in one of the eleventh and second cases 121 and 122.
上記実施例より明らかなように本考案によればハンガー
の上部に音孔を有する突部を設けたことにより風雑音を
効果的に除去できる特徴がある。As is clear from the above embodiments, the present invention has the feature that wind noise can be effectively removed by providing a protrusion with a sound hole on the upper part of the hanger.
またその突部はケースの接合面に設けるもので、成形時
に同時成形でき、製造が容易である。In addition, the protrusion is provided on the joint surface of the case, and can be molded at the same time as molding, making manufacturing easy.
