Description

本発明は、耳掛けタイプの補聴器に関する。 The present invention relates to an ear hook type hearing aid.

従来のこの種補聴器の構成は以下のようになっていた。
すなわち、耳の背面に装着される本体ケースと、この本体ケースにその一端側が連結され、他端側にはイヤーピースが連結されるひも状の音導体とを備えた構成となっており、前記音導体の他端側には、耳の対耳珠に係合させるひも状の係合具を取り付けていた（例えば、下記特許文献１）。 The configuration of this type of conventional hearing aid is as follows.
That is, the main body case is mounted on the back of the ear, and the main body case is connected to one end side of the main body case, and the other end side is connected to a string-like sound conductor to which the ear piece is connected. On the other end side of the conductor, a string-like engagement tool to be engaged with the ears of the ear is attached (for example, Patent Document 1 below).

つまり、本体ケースを耳の背面側に装着し、イヤーピースを外耳道に挿入後、前記係合具を耳の対耳珠に係合させることにより、イヤーピースが外耳道から外れないようにしたものである。 That is, the main body case is attached to the back side of the ear, the earpiece is inserted into the ear canal, and the engagement tool is engaged with the tragus of the ear so that the earpiece does not come off the ear canal.

米国特許出願公開第２００５／０００２５３９号明細書US Patent Application Publication No. 2005/0002539

従来例における課題は、耳の背面に装着される本体ケースが不安定であり、また、係合具の装着性が悪ことであった。すなわち、本体ケースは耳の背面に単に置かれ最短距離となる耳珠の近傍をひも状の音導体が配置されているだけで動きやすい為に装用感を阻害していた。また、この係合具の一端は音導体に結合されているが、その他端は遊端となっているので、この係合具を耳の対耳珠に係合させるためには前記一端側をつまんで、この係合具を変形させながら対耳珠に係合させる必要があり、このとき係合具はひも状でしかも小さな物であるので、これをつまんで前記対耳珠への係合作業は大変難しく、これが前述の装着性の悪さを引き起こすことになっていた。 The problem in the conventional example is that the main body case attached to the back of the ear is unstable, and the fitting property of the engaging tool is poor. That is, the main body case is simply placed on the back of the ear and has a string-like sound conductor disposed in the vicinity of the tragus which is the shortest distance, so that the wearing feeling is hindered. In addition, one end of the engagement tool is coupled to the sound conductor, but the other end is a free end. Therefore, in order to engage the engagement tool with the ear of the ear, the one end side is used. It is necessary to pinch and engage the anti-tragus while deforming the engaging tool. At this time, the engaging tool is a string-like and small object. The work was very difficult, and this was to cause the aforementioned poor wearability.

そこで、本発明は、装用感と装着性を向上することを目的とするものである。 SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to improve the feeling of wearing and the wearability.

そしてこの目的を達成するために、耳の背面に装着される本体ケースと、この本体ケースにその一端側が連結され、他端側にはイヤーピースが連結されるひも状の音導体とを備え、前記音導体の他端側は、前記イヤーピースの外耳道への挿入部上方を、このイヤーピースよりも前記本体ケース側に横切り、その後このイヤーピースへの挿入部よりも下方まで下げられた後に前記イヤーピースに連結される構成とし、この音導体の他端側で前記イヤーピースの挿入部よりも下方まで下げられた部分に、対耳珠への係合部を形成し、これにより所期の目的を達成するものである。 In order to achieve this object, a main body case to be mounted on the back of the ear, and a string-like sound conductor to which one end side is connected to the main body case and an ear piece is connected to the other end side, The other end side of the sound conductor is connected to the earpiece after traversing the upper part of the earpiece inserted into the ear canal to the side of the main body case from the earpiece, and then lowered to a position lower than the inserted part into the earpiece. And an engagement portion to the tragus is formed in a portion of the other end of the sound conductor that is lowered below the insertion portion of the earpiece, thereby achieving the intended purpose. is there.

以上のように本発明は、耳の背面に装着される本体ケースと、この本体ケースにその一端側が連結され、他端側にはイヤーピースが連結されるひも状の音導体とを備え、前記音導体の他端側は、前記イヤーピースの外耳道への挿入部上方を、このイヤーピースよりも前記本体ケース側に横切り、その後このイヤーピースへの挿入部よりも下方まで下げられた後に前記イヤーピースに連結される構成とし、この音導体の他端側で前記イヤーピースの挿入部よりも下方まで下げられた部分に、対耳珠への係合部を形成したものであるので、耳への装用感と装着性の向上を図ることができる。 As described above, the present invention includes a main body case attached to the back of the ear, and a string-like sound conductor having one end connected to the main body case and the earpiece connected to the other end. The other end side of the conductor is connected to the earpiece after traversing the upper part of the earpiece inserted into the ear canal to the side of the main body case than the earpiece, and then lowered to a position lower than the inserted part into the earpiece. Since the engaging portion to the anti-tragus is formed in the portion that is lowered below the insertion portion of the earpiece on the other end side of the sound conductor, the feeling of wearing and wearability to the ear Can be improved.

すなわち、本発明における前記音導体の他端側は、前記イヤーピースの外耳道への挿入部上方を、このイヤーピースよりも前記本体ケース側に横切り、その後このイヤーピースへの挿入部よりも下方まで下げられた後に前記イヤーピースに連結される構成とし、この音導体の他端側で前記イヤーピースの挿入部よりも下方まで下げられた部分に、対耳珠への係合部を形成したものであるので、係合部は音導体の他端側を一体的に構成したものとなり、従って、この係合部を耳の対耳珠に係合させるときに、指で対耳珠側に押し込むだけで良く、この結果として耳への装用感と装着性の向上を図ることができるものである。 That is, the other end side of the sound conductor according to the present invention traverses the upper part of the earpiece inserted into the ear canal to the side of the main body case rather than the earpiece, and then lowered to the lower part of the earpiece inserted part. It is configured to be connected to the earpiece later, and an engaging portion to the tragus is formed in a portion that is lowered below the insertion portion of the earpiece on the other end side of the sound conductor. The joint part is configured integrally with the other end side of the sound conductor. Therefore, when this engaging part is engaged with the antitragus of the ear, it is only necessary to push it into the antitragus side with a finger. As a result, it is possible to improve wear feeling and wearability to the ear.

以下に、本発明の一実施形態を図面とともに詳細に説明する。 Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.

（実施の形態１）
図１、図２は、本発明の一実施形態にかかる補聴器を耳に装着した状態を示し、耳１の
背面側には、本体ケース２が装着されている。この本体ケース２の上部には、ひも状の音導体３の一端を連結する結合部４が設けられており、この結合部４にひも状の音導体３の一端が連結されている。また、音導体３の他端側にはイヤーピース５が連結されており、このイヤーピース５は本実施形態においては全て図２のごとく外耳道６内に挿入されるようになっている。 (Embodiment 1)
1 and 2 show a state where a hearing aid according to an embodiment of the present invention is attached to an ear, and a main body case 2 is attached to the back side of the ear 1. On the upper part of the main body case 2, there is provided a coupling portion 4 for connecting one end of the string-like sound conductor 3, and one end of the string-like sound conductor 3 is connected to the coupling portion 4. Further, an ear piece 5 is connected to the other end side of the sound conductor 3, and this ear piece 5 is all inserted into the ear canal 6 as shown in FIG. 2 in this embodiment.

前記ひも状の音導体３は、図１〜図５から理解されるように、前記本体ケース２の上部の結合部４に連結される一端側から中部までの部分は、イヤーピース５の外耳道６の挿入部よりも本体ケース２とは反対側を下方に下がる延長部３ａとなっている。
また、この延長部３ａに続く中部３ｂは、イヤーピース５の外耳道６への挿入部上方を、このイヤーピース５よりも前記本体ケース２側に横切り、この中部３ｂに続く他端側は、前記イヤーピース５の挿入部よりも下方まで下げられた後に前記イヤーピース５に連結される構成となっている。 As can be understood from FIGS. 1 to 5, the string-like sound conductor 3 is connected to the coupling portion 4 at the upper part of the main body case 2 from the one end side to the middle portion of the earpiece 5. An extension portion 3a is provided that descends downward on the opposite side of the main body case 2 from the insertion portion.
Further, the middle part 3b following the extension part 3a crosses the insertion part of the earpiece 5 into the external auditory canal 6 so as to cross the body case 2 side from the earpiece 5, and the other end side following the middle part 3b is the earpiece 5 It is configured to be coupled to the earpiece 5 after being lowered below the insertion portion.

さらに、この音導体３の他端側で前記イヤーピース５の挿入部よりも下方まで下げられた部分に、対耳珠７への係合部３ｃを形成している。このため、補聴器を耳１に装着するときには、まず図１、図２に示すごとく本体ケース２を耳１の背面側に装着し、音導体３をこの耳１の上部に掛け、その後イヤーピース５を外耳道６内に挿入する。 Furthermore, an engaging portion 3 c to the anti-tragus 7 is formed at a portion of the other end of the sound conductor 3 that is lowered below the insertion portion of the earpiece 5. For this reason, when the hearing aid is attached to the ear 1, first, as shown in FIGS. 1 and 2, the main body case 2 is attached to the back side of the ear 1, the sound conductor 3 is hung on the upper portion of the ear 1, and then the earpiece 5 is attached. Insert into the ear canal 6.

そして、その状態においては、その音導体３の前記延長部３aにより、図１のごとく耳を本体ケース２と挟むことになり耳の背面に本体ケース２を保持することになる。また、その音導体３の前記係合部３ｃは図１の状態において対耳珠７の外側に位置しているので、指先でそれを図１のごとく対耳珠７に沿わせば、この音導体３自身が持っている弾性で対耳珠７に押し付けられ、この位置で安定した保持状態が保たれることになる。従って、図１の状態においては、イヤーピース５に連結された音導体３の他端側に一体形成した係合部３ｃが対耳珠７に係合した状態となっており、この結果としてイヤーピース５が外耳道６から不用意に抜け出すことは無い。 In this state, the extension 3a of the sound conductor 3 sandwiches the ear with the body case 2 as shown in FIG. 1, and the body case 2 is held on the back of the ear. Further, since the engaging portion 3c of the sound conductor 3 is located outside the anti-tragus 7 in the state shown in FIG. 1, if the fingertip is placed along the anti-oval 7 as shown in FIG. The conductor 3 itself is pressed against the anti-tragus 7 by elasticity, and a stable holding state is maintained at this position. Therefore, in the state of FIG. 1, the engaging portion 3 c integrally formed on the other end side of the sound conductor 3 connected to the earpiece 5 is engaged with the anticusp 7, and as a result, the earpiece 5 Does not inadvertently escape from the ear canal 6.

なお、音導体３は音道パイプにより形成する場合と、音道ワイヤーにより形成する場合があるが、図３に示すような形状、つまり、一端側から中部までの部分は、イヤーピース５の外耳道６の挿入部よりも本体ケース２とは反対側を下方に下がる延長部３ａとなっており、また、この延長部３ａに続く中部３ｂは、イヤーピース５の外耳道６への挿入部上方を、このイヤーピース５よりも前記本体ケース２側に横切り、さらに、この中部３ｂに続く他端側は、前記イヤーピース５の挿入部よりも下方まで下げられた後に前記イヤーピース５に連結され、この音導体３の他端側で前記イヤーピース５の挿入部よりも下方まで下げられた部分に、対耳珠７への係合部３ｃを形成した形状が保たれるようにしている。 The sound conductor 3 may be formed by a sound path pipe or a sound path wire, but the shape as shown in FIG. 3, that is, the part from one end side to the middle part is the ear canal 6 of the ear piece 5. An extension part 3a that goes downward on the opposite side of the main body case 2 from the insertion part of the earpiece 5 and the middle part 3b following the extension part 3a is located above the insertion part of the earpiece 5 to the ear canal 6. 5 is crossed to the main body case 2 side, and the other end side following the middle portion 3b is connected to the earpiece 5 after being lowered below the insertion portion of the earpiece 5, The shape formed with the engaging portion 3c for the anti-tragus 7 is maintained in the portion that is lowered below the insertion portion of the earpiece 5 on the end side.

但し、この音導体３は、ひも状の物であって弾性を有する物であるので上述した形状が保たれる物であっても、上述したごとく係合部３ｃを対耳珠７の外側から対耳珠７に押し込むときには容易に弾性変形して、この押し込み作業が簡単に行えるようになっている。
なお、前記係合部３ｃを含め音導体３全体は、その断面が円形となっているので、この係合部３ｃを対耳珠７に係合させていても痛感を伴わないものとなる。 However, since the sound conductor 3 is a string-like object having elasticity, even if the above-described shape is maintained, the engaging portion 3c is connected from the outside of the anticusp 7 as described above. When pushing into the anti-tragus 7, it is easily elastically deformed so that this pushing operation can be performed easily.
Since the entire sound conductor 3 including the engaging portion 3c has a circular cross section, even if the engaging portion 3c is engaged with the anti-tragus 7, no pain is felt.

すなわち、本発明における前記音導体の他端側は、前記イヤーピースの外耳道への挿入部上方を、このイヤーピースよりも前記本体ケース側に横切り、その後このイヤーピースへの挿入部よりも下方まで下げられた後に前記イヤーピースに連結される構成とし、この音導体の他端側で前記イヤーピースの挿入部よりも下方まで下げられた部分に、対耳珠への係合部を形成したものであるので、係合部は音導体の他端側を一体的に構成したものとなり、従って、この係合部を耳の対耳珠に係合させるときに、指で対耳珠に押し込むだけで良く、この結果として耳への装用感と装着性の向上を図ることができるのである。従って、補聴器としての活用が期待されるものである。 That is, the other end side of the sound conductor according to the present invention traverses the upper part of the earpiece inserted into the ear canal to the side of the main body case rather than the earpiece, and then lowered to the lower part of the earpiece inserted part. It is configured to be connected to the earpiece later, and an engaging portion to the tragus is formed in a portion that is lowered below the insertion portion of the earpiece on the other end side of the sound conductor. The joint portion is configured integrally with the other end side of the sound conductor. Therefore, when this engaging portion is engaged with the earlobe of the ear, it is only necessary to push it into the earlobe with a finger. As a result, it is possible to improve the wearing comfort and wearability of the ear. Therefore, utilization as a hearing aid is expected.
