本発明実施の形態は、電気振動変換器の筐体を概略長方体として、この筐体内部に、電磁型或いは圧電素子などで構成する、電気振動変換器を接着剤などで固定し、この変換器のアマチュアーを前記筐体の短辺面側の外部に突出させる。この外部に突出したアマチュアーの先端に、振動伝達部を接着剤などで固定する。この振動伝達部には装用幅調整アダプターを接着剤などで接合できる。そして筐体には突部が施工される。使用に供する時は、この突部を使用して外装ケースなどに組み込まれる。
【0013】
【実施例】
発明の実施の形態を実施例にもとづき図面を参照して説明する。
図1において、硬質部材を使用した筐体1に、電磁型あるいは圧電素子などによる、電気振動変換器2を接着剤などで固定する。この電気振動変換器2に施工されている鉄などを主成分としたアマチュアー3は、前記筐体1の短辺面側から突出し、この突出したアマチュアー3の先端に、硬質部材の振動伝達部4を接着剤などで固定する。軟質ゴムなどの防塵リング5は、筐体1と振動伝達部4の間隙部に施工をする。電気振動変換器2への入力端子6は、前記筐体1の振動伝達部4が施工されている反対側の短辺面に、接着剤などで固定されて、外耳道内挿入型骨伝導受話器となっている。
【0014】
図2は使用に供する時の一実施例で、筐体1に施工されている突部を使用し、本外耳道内挿入型骨伝導受話器が、外装ケースに組み込まれたものである。この実施例では電気振動変換器の電磁型による、一実施例を示したものである。プラグ本体11の内部で、外部入力用コード13とプラグ12が結線されている。外装ケース9に施工されているジャック孔10から、プラグ12を挿入すれば、接触バネ接点7に接触し導通状態が維持される。接触バネ接点7と接続されている入力端子6はスルーホール加工などで、出力増幅器17に半田ボンディングなどで接続されている。コイル16とコイル16aは中空構造の巻き線で、巻き始めと巻き終わりの電線を介して、出力増幅器17に接続されている。磁石15と磁石15aは永久磁石で、アマチュアー3の振幅方向両端に間隙を持って配され、ヨーク14とヨーク14aに、それぞれスポット溶接などで固定している。前記アマチュアー3はヨの字形状の中間に施工された可動片で、ヨの字形状の両端にあたる固定端は、ヨーク14とヨーク14aにそれぞれスポット溶接などで固定される。前記アマチュアー3は振動が励起される可動片で、図2の上下に振幅振動をする。
【0015】
図2における電気振動変換の概略は、外部入力コード13に印可された電気信号が、プラグ12を介して接触バネ接点7に伝えられ、入力端子6を経て出力増幅器17に入力される。この出力増幅器17で増幅された電気信号は、コイル16とコイル16aに入力され、入力された電気信号の変化に追従してアマチュアー3が励磁される。この励磁の状態を反映して、アマチュアー3は磁石14と磁石14aの間で振幅振動が励起される。このアマチュアー3の先端に固定されている振動伝達部4は、この振幅振動に同期する振幅振動をすることで、前記電気振動変換が行われることになる。
【0016】
図3は外装ケース9に組み込まれた本発明の骨伝導受話器21が、外耳道23内に装用された時の略図である。外耳道開口端24から挿入された、前記骨伝導受話器21の振動伝達部22は、略円筒形状の外耳道23の内壁25に圧接して装用される。即ち略円筒形状の外耳道23内壁25の両端面に、振動伝達部22が圧接する装用状態に保たれることになる。
【0017】
図4は本骨伝導受話器21の振動伝達部22を、外耳道23の内壁25に圧接する装用がされた部位を拡大した概略図である。振動伝達部22は、略円筒形状の外耳道23内壁25の皮膚34に接する。外耳道23内の皮膚34の周囲に骨28があり、前記振動伝達部22の振幅振動は、前記皮膚34を介して前記骨28に伝達される。この伝達された振幅振動を前記骨28が、骨伝導作用で図3で図示した中耳部36内耳部39などの聴覚器官に、骨伝導振動として伝達することになる。
【0018】
図5は装用幅調整アダプター関連の図である。本骨伝導受話器振動伝達部43に、装用幅調整アダプター40が接合される。ここで図3及び図4の外耳道23の略円筒形状の大きさなどが相違する場合に対しては、オプションとして用意される前記装用幅アダプター40と略近似形状で、大きさの違う装用幅調整アダプター大41、装用幅調整アダプター小42などで対応する。
【0019】
又、図3及び図4の外耳道23は各人毎に固有の形状を有しており、前記オプションで用意された図5のアダプター40などで対応不能の場合があるので、軟質プラスチックなどを使用し前記外耳道23の形状を採形し、プラスチックなどの硬質部材で別途装用幅調整アダプターを作成し、図5の振動伝達部43に接合することも可能である。
【0020】
図6は本発明の外耳道内挿入型骨伝導受話器を使用した、骨伝導補聴器の概略図である。骨伝導受話器部46は、外耳道内挿入型骨伝導受話器が組み込まれ、衝撃吸収効果のある軟質ゴムなどを使用した伝達振動抑制部44を介して、マイクロホン47などが組み込まれた補聴器の外装ケースと結合される。
【0021】
【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、以下に記載されるような効果を奏する。
【0022】
本発明の外耳道内挿入型骨伝導受話器は、外耳道内に挿入し使用するので、図3の中耳部36の耳小骨37や内耳部39の蝸牛30などの聴覚器官の近傍に、前記受話器の振動伝達部が装用されるので、伝達される振動の減衰は軽微であり、骨伝導による聴覚器官の聴感誘発を得やすい。一般的に媒質中の減衰は20logr1/r2で与えられ、距離が2倍、10倍になると単純にはそれぞれ−6dB、−20dBの減衰となるので、前記振動伝達部が前記聴覚器官近傍に装用される点は、優位性を有することになる。
【0023】
本発明の骨伝導受話器の振動伝達部は、アマチュアの先端に結合されるので、このアマチュアーの最大振幅を前記振動伝達部が振幅振動として、略円筒形状の外耳道内壁に圧接する両端面に伝達することになる。これは前記振動伝達部が片端面に接した状態と単純に比較して、振動伝達部位が2倍となるので、一般的に振動圧力の増加比は、20log2/1で表され、この場合は6dBの振動伝達増加比となるので、前記振動伝達部による効率的な振動伝達動作となる。
【0024】
図3において本発明の外耳道内挿入型骨伝導受話器を外耳道内に挿入すれば、外装ケースに組み込まれた骨伝導受話器21は、外耳道開口端24で保持されると共に、この受話器の振動伝達部22は、前記外耳道内内壁25の両端面に圧接する装用となり、特別な押圧付加機構を必要としない容易な装用とその維持が図れ、安定した骨伝導聴感を獲得出来るので、伝音難聴者などに対して利便を提供できる。
【0025】
本発明の骨伝導受話器の振動伝達部に、略円筒形状の外耳道の断面形状に近似の、図5に於ける装用幅調整アダプターを、オプションとして選択し接合することが可能である。又、特別な外耳道形状に近似の装用幅調整アダプターを作成し、前記振動伝達部に接合することも可能であるので、これらの装用幅調整アダプターを使用して、各固有の前記外耳道内壁へ最適な装用が可能となり、各人各様の外耳道条件に対し、前記振動伝達部の良好な装用の保持と、その維持を提供できる。
【0026】
図1において本骨伝導受話器に防塵リング5が施工されるが、電気振動変換器2への防塵の働きと、耳垢などの介在物の進入を阻む働きをする。又、前記振動伝達部4と前記電気振動変換器筐体1とが重なり合う構造なので、前記防塵リング5との相乗効果により、前記振動伝達部4の過大振動の抑制と、この振動伝達部4への過大負荷が要因となる、アマチュアー3の変形や損傷を防止できる。
【0027】
本発明の電気振動変換器の筐体内に出力増幅器を施工できる。図2におけるこの出力増幅器17の施工によれば、外部増幅回路の簡略化が図れるなどの効果がある。

When used, it is incorporated into an outer case or the like using this projection.
[0013]
【Example】
Embodiments of the present invention will be described based on examples with reference to the drawings.
In FIG. 1, an electric vibration converter 2 of an electromagnetic type or a piezoelectric element is fixed to a housing 1 using a hard member with an adhesive or the like. An armature 3 mainly composed of iron or the like, which is installed in the electric vibration converter 2, protrudes from the short side of the housing 1, and a vibration transmitting portion 4 of a hard member is attached to a tip of the protruding armature 3.

FIG. 2 shows an embodiment for use, in which the projections provided on the housing 1 are used, and the bone conduction receiver inserted into the external auditory canal is incorporated in an outer case. In this embodiment, an embodiment using an electromagnetic type electric vibration transducer is shown. Inside the plug body 11, the external input code 13 and the plug 12 are connected. When the plug 12 is inserted through the jack hole 10 formed in the outer case 9, the conductive member is kept in contact with the contact spring contact 7 when the plug 12 is inserted. The input terminal 6 connected to the contact spring contact 7 is connected to the output amplifier 17 by solder bonding or the like by through-hole processing or the like. The coil 16 and the coil 16a are windings having a hollow structure, and are connected to an output amplifier 17 via winding start and end wires.

FIG. 3 is a schematic view when the bone conduction receiver 21 of the present invention incorporated in the outer case 9 is worn in the external auditory canal 23. The vibration transmitting unit 22 of the bone conduction receiver 21 inserted from the ear canal opening end 24 is worn by being pressed against the inner wall 25 of the substantially cylindrical ear canal 23. That is, the vibration transmitting unit 22 is kept in a wearing state in which the vibration transmitting unit 22 is pressed against the both end surfaces of the inner wall 25 of the external ear canal 23 having a substantially cylindrical shape.
[0017]

【The invention's effect】
Since the present invention is configured as described above, it has the following effects.
[0022]
Since the bone conduction receiver inserted into the external auditory canal of the present invention is used by inserting it into the external auditory canal, it is located near an auditory organ such as the ossicle 37 of the middle ear 36 and the cochlea 30 of the inner ear 39 in FIG. Since the vibration transmission unit is worn, the transmitted vibration is slightly attenuated, and it is easy to induce the auditory sense of the hearing organ by bone conduction. Generally, the attenuation in a medium is given by 20logr1 / r2, and when the distance becomes twice and ten times, the attenuation becomes simply -6 dB and -20 dB, respectively. Therefore, the vibration transmitting unit is worn near the hearing organ. This is an advantage.
[0023]
Since the vibration transmitting portion of the bone conduction receiver according to the present invention is coupled to the tip of the armature, the maximum amplitude of the armature is transmitted as amplitude vibration to both end surfaces of the armature which are pressed against the inner wall of the external ear canal having a substantially cylindrical shape. Will be. This is because the vibration transmitting portion is doubled as compared with the state where the vibration transmitting portion is in contact with one end surface. Therefore, the increase ratio of the vibration pressure is generally expressed by 20 log 2/1. Since the vibration transmission increase ratio is 6 dB, an efficient vibration transmission operation by the vibration transmission unit is achieved.
[0024]
In FIG. 3, if the bone conduction handset of the present invention is inserted into the ear canal, the bone conduction receiver 21 incorporated in the outer case is held by the open end 24 of the ear canal and the vibration transmitting part 22 of the handset Can be worn by pressing against both end faces of the inner wall 25 of the ear canal, and can be easily worn without requiring a special pressing mechanism and can be maintained, so that a stable bone conduction hearing can be obtained. Convenience can be provided.
[0025]
The wearing width adjustment adapter shown in FIG. 5, which is similar to the cross-sectional shape of a substantially cylindrical external auditory canal, can be optionally selected and joined to the vibration transmitting portion of the bone conduction receiver of the present invention. It is also possible to create a wearing width adjustment adapter that approximates a special ear canal shape and join it to the vibration transmission section, so that these wearing width adjustment adapters can be used to optimally fit each unique ear canal inner wall. Therefore, it is possible to provide good holding and maintenance of the vibration transmission unit for various ear canal conditions.
