Description
本発明は、骨に振動を与えることで音を認識させる骨伝導を利用した聴音装置に関するものである。 The present invention relates to a sound-listening device that utilizes bone conduction to recognize sound by applying vibration to bone.
従来より、音楽や会話を聴く手段として、ヘッドホンやイヤホンなどのような装置（以下、聴音装置という。）が広く使用されてきている。このような聴音装置としては、空気振動を利用したものと骨伝導を利用したものとがある。空気振動を利用したものは、電気信号として入力された音源を空気振動に変換して鼓膜に伝えて振動させ、鼓膜の振動が耳の奥の中耳を通って、脳に音の情報が伝達され認識される仕組みを利用している。 Conventionally, devices such as headphones and earphones (hereinafter referred to as listening devices) have been widely used as means for listening to music and conversation. Such hearing devices include those using air vibration and those using bone conduction. In the case of using air vibration, the sound source input as an electric signal is converted into air vibration and transmitted to the eardrum to vibrate, and the vibration of the eardrum passes through the middle ear behind the ear and the sound information is transmitted to the brain. It uses a mechanism that is recognized and recognized.
一方、骨伝導を利用した聴音装置は、電気信号として入力された音響信号を機械的な振動に変換し、その振動を適切な位置から骨に与えて骨に振動を伝え、その振動により伝わる骨伝導音で音を認識させるものである。この骨伝導を利用した聴音装置は、ヘッドホンやイヤホンのように耳孔に挿入して使用する必要がなく、耳には周囲の音が遮蔽されることなく入ってくるので、装着していても安全である。また、鼓膜の振動を利用しないことから、難聴の人でも音を認識することができ、補聴器等への利用も進められている（例えば特許文献１）。 On the other hand, a hearing device using bone conduction converts an acoustic signal input as an electric signal into mechanical vibration, applies the vibration to the bone from an appropriate position, transmits the vibration to the bone, and transmits the vibration to the bone. The sound is recognized by the conduction sound. Unlike headphones and earphones, this bone conduction listening device does not need to be inserted into the ear canal and enters the ear without blocking the surrounding sound, so it is safe to wear. Is. Further, since the vibration of the eardrum is not used, even a person with hearing loss can recognize the sound, and its use in hearing aids and the like is being promoted (for example, Patent Document 1).
このような骨伝導を利用した聴音装置は、振動部を適切な位置に当接させることで聴音が可能となる。適切な位置としては、例えば、こめかみや乳様突起と呼ばれる部位が挙げられる。 A sound-listening device utilizing such bone conduction can hear sound by bringing the vibrating portion into contact with an appropriate position. Suitable positions include, for example, sites called temples and mastoid processes.
しかし、発明者は、鋭意研究の結果、頭蓋骨ではなく、耳介の軟骨に音を伝えることで、より小さなパワーで大きな音量を得ることができることを見出した。この場合には、聴音装置を耳介に確実に固定可能な方法が望まれる。 However, as a result of diligent research, the inventor has found that by transmitting sound to the cartilage of the auricle instead of the skull, it is possible to obtain a loud volume with a smaller power. In this case, a method capable of reliably fixing the hearing device to the pinna is desired.
このような聴音装置を耳介に固定する方法としては、例えば、聴音装置によって耳介を挟み込むように装着する方法が考えられる。しかし、例えば、耳介の表側に振動部を配置する場合には、振動部や、振動部を制御し駆動するための基板やバッテリーなどの本体部が耳介の前方に配置されるため、聴音装置が目立ち、また、耳介の前方に配置される聴音装置が大型化するため、装着性が悪化する。 As a method of fixing such a hearing device to the auricle, for example, a method of wearing the auricle so as to be sandwiched by the hearing device can be considered. However, for example, when the vibrating part is arranged on the front side of the auricle, the vibrating part and the main body such as the substrate and the battery for controlling and driving the vibrating part are arranged in front of the auricle, so that the sound is heard. Since the device is conspicuous and the hearing device placed in front of the auricle becomes large, the wearability is deteriorated.
本発明は、このような問題に鑑みてなされたもので、装着性に優れ、コンパクトな聴音装置を提供することを目的とする。 The present invention has been made in view of such a problem, and an object of the present invention is to provide a compact listening device having excellent wearability.

It is provided with a connecting portion for mounting on the ear and a first vibrating portion housed in one of the sandwiching bodies, which converts an acoustic electric signal into vibration and outputs the vibration, and the connecting portion is an elastic body. By the elastic force of the connecting portion, the auricle is sandwiched between the pair of the holding bodies from the front side and the back side, and the hearing device is held in a state where the holding body is in close contact with the auricle, and the hearing device is attached . It is possible (except for those that are hooked on the upper part of the ear and have a hearing device attached) , and it is smaller than the other holding body and can be attached so as to fit into the concave portion on the front surface of the auricle above the auricle. One holding body is provided with a transmission surface that contacts the front side of the ear and transmits vibration, and the connecting portion accommodates an electric wire, and the other holding body arranged behind the pinna is described as described above. It is a sound-listening device characterized in that an electric signal is transmitted to the first vibrating portion inside one of the sandwiching bodies.
前記他方の挟持体には、前記第１の振動部を駆動する基板とバッテリーとが収容されてもよい。 The other holding body may accommodate a substrate for driving the first vibrating portion and a battery.
前記一方の挟持体の伝達面が、前記他方の挟持体に対向する向きに形成されてもよい。 The transmission surface of the one holding body may be formed so as to face the other holding body.
前記一方の挟持体の伝達面が、前記他方の挟持体に対向する向きとは異なる方向に向けて形成されてもよい。 The transmission surface of the one holding body may be formed in a direction different from the direction facing the other holding body.
前記一方の挟持体は、前記他方の挟持体に対して前記伝達面の向きを変えた状態で維持することが可能であってもよい。
前記連結部と前記一方の挟持体との接続部に、回転部が設けられてもよい。
前記連結部と前記一方の挟持体は、脱着可能であり、前記一方の挟持体を前記連結部に対して任意の角度で取り付けることが可能であってもよい。
The one holding body may be able to be maintained in a state where the direction of the transmission surface is changed with respect to the other holding body.
A rotating portion may be provided at the connecting portion between the connecting portion and the one holding body.
The connecting portion and the one holding body may be detachable, and the one holding body may be attached to the connecting portion at an arbitrary angle.
前記他方の挟持体には、音響電気信号を振動に変換して振動を出力する第２の振動部が収容され、耳の表側及び耳の裏側に対して、前記第１の振動部と前記第２の振動部によって振動を伝達可能であってもよい。 The other holding body accommodates a second vibrating portion that converts an acoustic electric signal into vibration and outputs the vibration, and the first vibrating portion and the first vibrating portion with respect to the front side and the back side of the ear. Vibration may be transmitted by the vibrating portion of 2.
本発明によれば、聴音装置が耳介を表裏から挟み込むように取り付けられ、第１の振動部が収容される一方の挟持体と、第１の振動部に電気信号を伝送する他方の挟持体とが別々に構成される。このため、第１の振動部が収容される一方の挟持体をコンパクトにすることができ、第１の挟持体の伝達面を効率よく耳介に接触させることができる。特に、一方の挟持体を耳介の表側に配置する場合でも、目立ちにくく見た目にも優れる。 According to the present invention, the hearing device is attached so as to sandwich the pinna from the front and back, and one holding body in which the first vibrating portion is accommodated and the other holding body for transmitting an electric signal to the first vibrating portion. And are configured separately. Therefore, one of the holding bodies in which the first vibrating portion is housed can be made compact, and the transmission surface of the first holding body can be efficiently brought into contact with the auricle. In particular, even when one of the holding bodies is arranged on the front side of the pinna, it is inconspicuous and has an excellent appearance.
また、他方の挟持体に、第１の振動部を駆動する基板とバッテリーとを収容することで、聴音装置をワイヤレス化することができる。この際、第１の振動部が収容される一方の挟持体と、基板とバッテリーとが収容される他方の挟持体とが別体であるため、いずれかの挟持体が大型化することを抑制することができる。 Further, by accommodating the substrate for driving the first vibrating portion and the battery in the other holding body, the sound listening device can be made wireless. At this time, since one holding body in which the first vibrating portion is housed and the other holding body in which the substrate and the battery are housed are separate bodies, it is possible to prevent one of the holding bodies from becoming large. can do.
ここで、一方の挟持体の伝達面が、他方の挟持体に対向する向きに形成されてもよく、一方の挟持体の伝達面が、他方の挟持体に対向する向きとは異なる方向に向けて形成されてもよい。伝達面の向きは、使用者の耳の形状に応じて適用することができる。 Here, the transmission surface of one holding body may be formed in a direction facing the other holding body, and the transmission surface of one holding body may be oriented in a direction different from the direction facing the other holding body. May be formed. The orientation of the transmission surface can be applied according to the shape of the user's ear.
また、一方の挟持体が、他方の挟持体に対して伝達面の向きを変えることが可能であれば、取り付ける耳介の形状や、音の聞こえ方などに合わせて、耳介の適切な部位に伝達面を接触させることができる。 If one of the pincers can change the direction of the transmission surface with respect to the other pinch, the appropriate part of the pinna according to the shape of the pinna to be attached and how the sound is heard. The transmission surface can be brought into contact with the ear.
また、一対の挟持体のそれぞれに振動部を収容し、耳介の表裏から挟み込むことで、耳介の表側と裏側の両方から、耳介に振動を伝達することができる。このため、より効率よく耳介へ振動を伝達することができる。 Further, by accommodating the vibrating portion in each of the pair of holding bodies and sandwiching the vibrating portion from the front and back sides of the auricle, vibration can be transmitted to the auricle from both the front side and the back side of the auricle. Therefore, the vibration can be transmitted to the auricle more efficiently.
本発明によれば、装着性に優れ、コンパクトな聴音装置を提供することができる。 According to the present invention, it is possible to provide a compact listening device having excellent wearability.
以下、図面を参照しながら、本発明の第１の実施形態について説明する。図１は、聴音装置１の斜視図、図２（ａ）は聴音装置１の側面図、図２（ｂ）は聴音装置１の平面図、図２（ｃ）は、聴音装置１の底面図、図２（ｄ）は聴音装置１の正面図、図２（ｅ）は聴音装置１の背面図である。また、図３は、聴音装置１の構成を示す概念図である。骨伝導を利用する聴音装置１は、主に、挟持体３ａ、３ｂ、連結部５、振動部７、基板９、バッテリー１１等から構成される。 Hereinafter, the first embodiment of the present invention will be described with reference to the drawings. 1 is a perspective view of the listening device 1, FIG. 2A is a side view of the listening device 1, FIG. 2B is a plan view of the listening device 1, and FIG. 2C is a bottom view of the listening device 1. 2 (d) is a front view of the hearing device 1, and FIG. 2 (e) is a rear view of the listening device 1. Further, FIG. 3 is a conceptual diagram showing the configuration of the listening device 1. The hearing device 1 utilizing bone conduction is mainly composed of a holding body 3a, 3b, a connecting portion 5, a vibrating portion 7, a substrate 9, a battery 11, and the like.
一対の挟持体３ａ、３ｂは、所定の間隔をあけて対向して配置され、連結部５で連結される。連結部５は弾性体であり、挟持体３ａ、３ｂで耳介を挟み込んだ状態で聴音装置１を保持し、聴音装置１を耳に装着することができる。すなわち、挟持体３ａ、３ｂは耳介を表側と裏側から挟み込む部位である。 The pair of sandwiching bodies 3a and 3b are arranged so as to face each other with a predetermined interval, and are connected by the connecting portion 5. The connecting portion 5 is an elastic body, and the hearing device 1 can be held in a state where the auricle is sandwiched between the holding bodies 3a and 3b, and the listening device 1 can be attached to the ear. That is, the sandwiching bodies 3a and 3b are portions that sandwich the auricle from the front side and the back side.
図３に示すように、一方の挟持体３ａの内部には、第１の振動部である振動部７が収容される。振動部７は、電気信号として入力された音響信号を機械的な振動に変換して振動を出力する部位である。なお、音響電気信号を振動に変換するとは、外部から入力された音響電気信号を機械振動に変換することであり、例えば、音響電気信号によってダイヤフラム等を振動させることで、音響電気信号を骨に伝達する機械振動に変換する。なお、本発明においては、振動部７における振動方式は、特に限定されるものではなく、音響電気信号を機械振動に変換できればよく、圧電式、電磁式、超磁歪など、従来から用いられている方法を採用することができる。 As shown in FIG. 3, a vibrating portion 7, which is a first vibrating portion, is housed inside one of the sandwiching bodies 3a. The vibration unit 7 is a portion that converts an acoustic signal input as an electric signal into mechanical vibration and outputs the vibration. It should be noted that converting an acoustic electric signal into vibration means converting an acoustic electric signal input from the outside into mechanical vibration. For example, by vibrating a diaphragm or the like by the acoustic electric signal, the acoustic electric signal becomes a bone. Converts to transmitted mechanical vibration. In the present invention, the vibration method in the vibrating unit 7 is not particularly limited as long as it can convert an acoustic electric signal into mechanical vibration, and has been conventionally used such as a piezoelectric type, an electromagnetic type, and a giant magnetostriction. The method can be adopted.
このようにして得られる振動は、挟持体３ａの一方の面における伝達面１５から利用者の骨に伝達される。本実施形態では、挟持体３ａの伝達面１５は、挟持体３ｂに対向する向きに形成される。なお、振動部７の振動が挟持体３ａの筐体等に伝わることを抑制するため、所定の部位に制振材８を配置してもよい。 The vibration thus obtained is transmitted to the user's bone from the transmission surface 15 on one surface of the holding body 3a. In the present embodiment, the transmission surface 15 of the sandwiching body 3a is formed so as to face the sandwiching body 3b. In addition, in order to suppress the vibration of the vibrating portion 7 from being transmitted to the housing or the like of the sandwiching body 3a, the vibration damping material 8 may be arranged at a predetermined portion.
ここで、挟持体３ａから耳介の軟骨へ効率よく振動を伝達するためには、挟持体３ａの伝達面１５が耳介の小さなスペースに配置できるように、挟持体３ａのサイズは、十分に小さいことが望ましい。例えば、１０φ以下のサイズの振動子を用いることで、挟持体３ａのサイズを小さくすることができるため望ましい。 Here, in order to efficiently transmit vibration from the pinch body 3a to the cartilage of the pinna, the size of the pinch body 3a is sufficient so that the transmission surface 15 of the pinch body 3a can be arranged in a small space of the pinna. Small is desirable. For example, it is desirable to use an oscillator having a size of 10φ or less because the size of the sandwiching body 3a can be reduced.
挟持体３ａの伝達面１５は、装着者の皮膚に直接触れるので、装着時に痛みや不快感を与えない素材で構成される。例えば、合成樹脂や合成ゴム等が挙げられ、これに限られないが、耳介に当接するものであるため、可撓性や柔軟性を有する素材で構成されることが好ましい。 Since the transmission surface 15 of the sandwiching body 3a comes into direct contact with the wearer's skin, it is made of a material that does not cause pain or discomfort when worn. Examples thereof include, but are not limited to, synthetic resin and synthetic rubber, and are preferably made of a flexible or flexible material because they come into contact with the auricle.
他方の挟持体３ｂには、振動部７を駆動する基板９とバッテリー１１等が収容される。基板９は、振動部７を制御する制御部や、無線通信を行う通信部等を有する。例えば、通信部は、他の端末等からの音響電気信号を無線で受信する受信部を有し、無線（例えばＢｌｕｅｔｏｏｔｈ（登録商標））などの近距離無線通信を行うことができる。また、この他、聴音装置１の操作部や音楽情報を記憶する記憶部等を有していてもよい。 The other holding body 3b accommodates a substrate 9 for driving the vibrating portion 7, a battery 11, and the like. The substrate 9 has a control unit that controls the vibration unit 7, a communication unit that performs wireless communication, and the like. For example, the communication unit has a reception unit that wirelessly receives an acoustic electric signal from another terminal or the like, and can perform short-range wireless communication such as wireless (for example, Bluetooth (registered trademark)). In addition, it may have an operation unit of the listening device 1, a storage unit for storing music information, and the like.
なお、聴音装置１は、片耳で用いられてもよく、右耳用と左耳用のセットで用いられてもよい。この際、一対の聴音装置１の通信部同士は有線で接続されてもよく、または、近距離磁気誘導方式などの無線通信で接続されてもよい。 The listening device 1 may be used for one ear or may be used as a set for the right ear and the left ear. At this time, the communication units of the pair of sound listening devices 1 may be connected by wire, or may be connected by wireless communication such as a short-range magnetic induction method.
挟持体３ｂ内部の基板９と、挟持体３ａ内部の振動部７とは、電線１３で接続される。電線１３は、連結部５に収容され、挟持体３ｂから挟持体３ａの内部の振動部７へ電気信号が伝送される。すなわち、本発明では、挟持体３ａには、基板９やバッテリー１１が収容されず、挟持体３ａとは別の挟持体３ｂに配置される。このため、挟持体３ａが大型化することを抑制することができる。 The substrate 9 inside the sandwiching body 3b and the vibrating portion 7 inside the sandwiching body 3a are connected by an electric wire 13. The electric wire 13 is housed in the connecting portion 5, and an electric signal is transmitted from the sandwiching body 3b to the vibrating portion 7 inside the sandwiching body 3a. That is, in the present invention, the substrate 9 and the battery 11 are not accommodated in the holding body 3a, and are arranged in the holding body 3b different from the holding body 3a. Therefore, it is possible to prevent the sandwiching body 3a from becoming large.
次に、聴音装置１の使用方法について説明する。図４は、利用者が聴音装置１を装着した状態を示す概念図（耳介２１の一部断面図）である。なお、利用者の右耳に聴音装置１を装着した例について説明するが、左耳についても対称に装着可能である。また、以下の説明では、伝達面１５は、耳介の表側に接触して振動を伝達する例を説明するが、挟持体３ａの伝達面１５は、耳介の裏側に接触して振動を伝達してもよい。 Next, a method of using the sound listening device 1 will be described. FIG. 4 is a conceptual diagram (a partial cross-sectional view of the pinna 21) showing a state in which the user wears the hearing device 1. Although an example in which the hearing device 1 is attached to the user's right ear will be described, the left ear can also be attached symmetrically. Further, in the following description, an example in which the transmission surface 15 contacts the front side of the auricle to transmit vibration will be described, but the transmission surface 15 of the sandwiching body 3a contacts the back side of the auricle to transmit vibration. You may.
本発明にかかる聴音装置１は、挟持体３ａ、３ｂで耳介２１を挟み込むようにして装着される。この際、前述したように、連結部５が弾性体であるため、連結部５の弾性力によって挟持体３ａ、３ｂが耳介２１に密着して装着された状態が保持される。 The hearing device 1 according to the present invention is attached so as to sandwich the auricle 21 between the holding bodies 3a and 3b. At this time, as described above, since the connecting portion 5 is an elastic body, the state in which the holding bodies 3a and 3b are closely attached to the auricle 21 is maintained by the elastic force of the connecting portion 5.
聴音装置１を耳介２１に装着すると、挟持体３ａの伝達面１５は、耳介２１の表側（図４の右側）に当接され、挟持体３ｂは耳介２１の裏側に当接される。より詳細には、挟持体３ａは、耳介２１の前面の凹部（耳たぶより上方の凹部）に嵌るように装着され、伝達面１５は、挟持体３ｂとの対向方向であって、耳介２１の凹部の上面近傍に密着する。このようにすることで、利用者が聴音装置１を装着した際のフィット感を得ることができ、伝達面１５からの振動を効率よく耳介２１の軟骨へ伝達することができる。 When the hearing device 1 is attached to the pinna 21, the transmission surface 15 of the pinch body 3a is in contact with the front side of the pinna 21 (right side in FIG. 4), and the pinch body 3b is in contact with the back side of the pinna 21. .. More specifically, the pinching body 3a is mounted so as to fit into a recess (a recess above the earlobe) on the front surface of the pinna 21, and the transmission surface 15 is in a direction facing the pinching body 3b and is opposed to the pinna 21. Adheres to the vicinity of the upper surface of the recess. By doing so, it is possible to obtain a fit feeling when the user wears the hearing device 1, and it is possible to efficiently transmit the vibration from the transmission surface 15 to the cartilage of the auricle 21.
以上、本実施の形態によれば、挟持体３ａ、３ｂのそれぞれに、振動部７と、基板９及びバッテリー１１を分けて配置することで、一方の挟持体が大型化することを抑制することができる。特に、耳介２１の前面に配置される挟持体３ａには振動部７のみが収容されるため、挟持体３ｂと比較して小型化することができ、装着性がよく、見た目にも目立ちにくい。また、基板９及びバッテリー１１が収容される挟持体３ｂは、耳介２１の後ろ側に配置されるため目立ちにくい。 As described above, according to the present embodiment, by separately arranging the vibrating portion 7, the substrate 9, and the battery 11 in each of the sandwiching bodies 3a and 3b, it is possible to prevent one of the sandwiching bodies from becoming large. Can be done. In particular, since only the vibrating portion 7 is housed in the holding body 3a arranged on the front surface of the pinna 21, the size can be reduced as compared with the holding body 3b, the wearability is good, and the appearance is not noticeable. .. Further, the holding body 3b in which the substrate 9 and the battery 11 are housed is arranged behind the pinna 21 and is therefore inconspicuous.
また、弾性体であるアーム状の連結部５によって、伝達面１５を皮膚へ密着させることができるため、簡易な構造で、確実に振動を耳介２１の軟骨に伝達することができる。 Further, since the transmission surface 15 can be brought into close contact with the skin by the arm-shaped connecting portion 5 which is an elastic body, the vibration can be reliably transmitted to the cartilage of the auricle 21 with a simple structure.
次に、第２の実施形態について説明する。図５（ａ）は、聴音装置１ａの側面図、図５（ｂ）は聴音装置１ａの平面図である。なお、以下の説明において、聴音装置１と同様の構成については、図１～図４と同一の符号を付し、重複する説明を省略する。 Next, the second embodiment will be described. 5A is a side view of the listening device 1a, and FIG. 5B is a plan view of the listening device 1a. In the following description, the same components as those of the listening device 1 are designated by the same reference numerals as those in FIGS. 1 to 4, and duplicated description will be omitted.
聴音装置１ａは、聴音装置１とほぼ同様の構成であるが、伝達面１５の向きが異なる。このように、挟持体３ａの伝達面１５の向きを、挟持体３ｂに対向する向きとは異なる方向に向けて形成してもよい。 The listening device 1a has almost the same configuration as the listening device 1, but the orientation of the transmission surface 15 is different. In this way, the direction of the transmission surface 15 of the holding body 3a may be formed so as to be different from the direction facing the holding body 3b.
図６は、利用者が聴音装置１ａを装着した状態を示す概念図（耳介２１の一部断面図）である。この場合には、挟持体３ａの側面と挟持体３ｂとで耳介２１が挟み込まれる。聴音装置１ａを耳介２１に装着すると、挟持体３ａは、耳介２１の前面の凹部（耳たぶより上方の凹部）に嵌るように装着され、伝達面１５は、耳介２１の凹部の前方側近傍に密着する。 FIG. 6 is a conceptual diagram (a partial cross-sectional view of the pinna 21) showing a state in which the user wears the hearing device 1a. In this case, the pinna 21 is sandwiched between the side surface of the holding body 3a and the holding body 3b. When the hearing device 1a is attached to the auricle 21, the holding body 3a is attached so as to fit into the concave portion (recess above the earlobe) on the front surface of the auricle 21, and the transmission surface 15 is on the front side of the concave portion of the auricle 21. Adhere to the neighborhood.
なお、なお、図示した例では、伝達面１５が、挟持体３ｂとの対向方向に対して略９０度横に向いた形態であるが、伝達面１５の角度は、図示した例には限られない。挟持体３ａ、３ｂの挟持方向に対する伝達面１５の向きは、耳介２１の形態などによって適宜設定されればよい。 In the illustrated example, the transmission surface 15 is oriented laterally by approximately 90 degrees with respect to the direction facing the sandwiching body 3b, but the angle of the transmission surface 15 is limited to the illustrated example. do not have. The orientation of the transmission surface 15 with respect to the pinching direction of the pinching bodies 3a and 3b may be appropriately set depending on the shape of the pinna 21 and the like.
第２の実施形態によれば、第１の実施形態と同様の効果を得ることができる。このように、伝達面１５は、必ずしも、挟持体３ａ、３ｂの挟持方向と一致していなくてもよい。耳介２１の一部に伝達面１５を接触させることが可能であれば、あえて伝達面１５の向きを変えることで、聴音装置１ａの装着時のフィット感を向上させたり、振動の伝達させやすい部位に対して伝達面１５を接触させることができる。 According to the second embodiment, the same effect as that of the first embodiment can be obtained. As described above, the transmission surface 15 does not necessarily have to coincide with the sandwiching direction of the sandwiching bodies 3a and 3b. If it is possible to bring the transmission surface 15 into contact with a part of the auricle 21, it is easy to improve the fit when the listening device 1a is attached or to transmit vibration by intentionally changing the direction of the transmission surface 15. The transmission surface 15 can be brought into contact with the site.
次に、第３の実施形態について説明する。図７（ａ）は、聴音装置１ｂの側面図、図７（ｂ）は聴音装置１ｂの平面図である。聴音装置１ｂは聴音装置１等とほぼ同様の構成であるが、回転部１７が設けられる点で異なる。聴音装置１ｂには、連結部５と挟持体３ａとの接続部に回転部１７が設けられる。回転部１７は、挟持体３ａ、３ｂの挟持方向に略直交する方向を回転軸として連結部５に対して挟持体３ａの向きを任意に変更可能である。 Next, a third embodiment will be described. 7 (a) is a side view of the hearing device 1b, and FIG. 7 (b) is a plan view of the listening device 1b. The listening device 1b has almost the same configuration as the listening device 1 and the like, but differs in that a rotating portion 17 is provided. The sound listening device 1b is provided with a rotating portion 17 at a connecting portion between the connecting portion 5 and the holding body 3a. The rotating portion 17 can arbitrarily change the direction of the sandwiching body 3a with respect to the connecting portion 5 with the direction substantially orthogonal to the sandwiching direction of the sandwiching bodies 3a and 3b as the rotation axis.
第３の実施形態によれば、第１の実施形態と同様の効果を得ることができる。また、このようにすることで、挟持体３ａの向きを利用者の耳介２１の形状に合わせて調整が可能である。 According to the third embodiment, the same effect as that of the first embodiment can be obtained. Further, by doing so, the orientation of the holding body 3a can be adjusted according to the shape of the user's auricle 21.
なお、挟持体３ａの伝達面１５の向きを変える方法としては、図示したような回転部１７を設けるのではなく、例えば、連結部５を任意の形状に変形可能としてもよく、または、挟持体３ａと連結部５とを脱着可能として、任意の角度で取り付けることが可能であってもよい。 As a method of changing the direction of the transmission surface 15 of the sandwiching body 3a, for example, the connecting portion 5 may be deformed into an arbitrary shape instead of providing the rotating portion 17 as shown in the figure, or the sandwiching body. The 3a and the connecting portion 5 may be detachable and can be attached at any angle.
次に、第４の実施形態について説明する。図８は、聴音装置１ｃの構成を示す概念図である。聴音装置１ｃは聴音装置１等とほぼ同様の構成であるが、挟持体３ｂ内部にバッテリー１１等が収容されない点で異なる。 Next, a fourth embodiment will be described. FIG. 8 is a conceptual diagram showing the configuration of the listening device 1c. The listening device 1c has almost the same configuration as the listening device 1 and the like, except that the battery 11 and the like are not housed inside the holding body 3b.
聴音装置１ｃは、挟持体３ｂに接続部２５を設け、他の機器等のケーブル１９とコネクタ２３を介して接続可能である。例えば、音響電気信号を他の機器から有線で聴音装置１ｃへ伝送することができるとともに、ケーブル１９によって聴音装置１ｃへ電力を供給することもできる。 The listening device 1c is provided with a connecting portion 25 on the holding body 3b, and can be connected to a cable 19 of another device or the like via the connector 23. For example, an acoustic electric signal can be transmitted from another device to the listening device 1c by wire, and power can be supplied to the listening device 1c by a cable 19.
また、前述した聴音装置１等に対して接続部２５を設け、コネクタ２３によって外部マイクを接続可能としてもよい。この場合には、マイクで集音した音の音響電気信号を振動部７へ伝送することで、聴音装置１ｃを補聴器として利用することもできる。 Further, the connection unit 25 may be provided for the sound listening device 1 or the like described above, and the external microphone may be connected by the connector 23. In this case, the hearing device 1c can also be used as a hearing aid by transmitting the acoustic electric signal of the sound collected by the microphone to the vibrating unit 7.
第４の実施形態によれば、第１の実施形態と同様の効果を得ることができる。このように、挟持体３ｂの内部に収容される構成は、特に限定されない。 According to the fourth embodiment, the same effect as that of the first embodiment can be obtained. As described above, the configuration accommodated inside the sandwiching body 3b is not particularly limited.
次に、第５の実施形態について説明する。図９は、聴音装置１ｄの構成を示す概念図である。聴音装置１ｄは聴音装置１等とほぼ同様の構成であるが、挟持体３ｂに、第２の振動部である振動部７ａを収容される点で異なる。すなわち、挟持体３ｂにも振動部７ａの振動を伝達する伝達面１５ａが形成される。図示した例では、伝達面１５と伝達面１５ａとが互いに対向する。 Next, a fifth embodiment will be described. FIG. 9 is a conceptual diagram showing the configuration of the listening device 1d. The listening device 1d has almost the same configuration as the listening device 1 and the like, except that the holding body 3b accommodates the vibrating portion 7a, which is the second vibrating portion. That is, a transmission surface 15a for transmitting the vibration of the vibrating portion 7a is also formed on the sandwiching body 3b. In the illustrated example, the transmission surface 15 and the transmission surface 15a face each other.
この場合には、例えば、伝達面１５、１５ａによって耳介２１を挟み込むと、それぞれの伝達面１５、１５ａから耳介２１へ振動が伝達される。すなわち、耳介２１の表側と裏側の両側に対して、振動部７、７ａによって振動を伝達可能である。 In this case, for example, when the auricle 21 is sandwiched between the transmission surfaces 15 and 15a, vibration is transmitted from the respective transmission surfaces 15 and 15a to the auricle 21. That is, vibration can be transmitted to both the front side and the back side of the auricle 21 by the vibrating portions 7 and 7a.
第５の実施形態によれば、第１の実施形態と同様の効果を得ることができる。また、耳介２１の表側と裏側の両側に対して振動を伝達可能であるため、より効率よく耳介２１へ振動を伝達することができる。なお、この場合でも、伝達面１５と伝達面１５ａとが必ずしも互いに対向して配置されなくてもよい。伝達面１５は、伝達面１５ａとの対向方向とは異なる方向に向けて配置してもよい。 According to the fifth embodiment, the same effect as that of the first embodiment can be obtained. Further, since the vibration can be transmitted to both the front side and the back side of the auricle 21, the vibration can be transmitted to the auricle 21 more efficiently. Even in this case, the transmission surface 15 and the transmission surface 15a do not necessarily have to be arranged so as to face each other. The transmission surface 15 may be arranged in a direction different from the direction facing the transmission surface 15a.
