Description

【０００１】
【発明の属する技術分野】
本発明は骨伝導デバイスを用いた送受話装置、より詳細には、外耳道を塞がず、且つ、使用中使用者に痛感を与えない骨伝導スピーカ及び骨伝導マイクを併せ有する送受話装置に関するものである。以下、「骨伝導デバイス」なる語は、骨伝導スピーカと骨伝導マイクとを包括したものとして使用する。
【０００２】
【従来の技術】
受話装置として一般に用いられているイヤホンは、音圧スピーカから発生される音を空気振動によって人間の鼓膜へ伝えるもので、先端部が外耳道内に挿入され、外耳道を塞いだ状態で使用される。
【０００３】
上記のようなタイプのイヤホンの使用時には、外耳道が閉塞されるために周囲の音が聞き取りにくくなり、車両の運転中に危険が伴ったり、会話の際に無意識に声が大きくなったりしてしまうといった不都合がある。また、高温多湿の環境では、外耳道内が蒸れるために不快感を伴い、衛生面においても好ましくない。
【０００４】
外耳道を塞がずに音を聞く手段として、頭部の骨格の硬い部分に骨伝導スピーカの振動面を一定の圧力で押し当てるタイプの受話装置があるが、この受話装置の場合は、長時間使用していると骨伝導スピーカとの接触面に痛感を覚えたり、骨伝導スピーカの接触の角度によっては音が聞きづらくなるといった欠点がある。また、頭部形状には個人差があるため、全ての人に快適な装着感を実現することは困難である。
【０００５】
更に、このタイプの受話装置の一実施形態として、骨伝導スピーカを頭部に圧接固定するものがあるが、この場合には頭部を取り巻く保持具が必要となり、それは大掛かりなものとなって、装着時に目立ちやすく、外観もあまり良くない。
【０００６】
【発明が解決しようとする課題】
本発明は、上記従来の送受話装置における問題点に鑑みてなされたもので、骨伝導スピーカ及び骨伝導マイクを用いた受話装置でありながら、骨格形成部に圧接させる必要がないために使用中に痛感を覚えることがなく、外耳道を閉塞しないために外部音の聴取に支障がなく、しかも良好な受信音を聴取し、また、送信することができる骨伝導デバイスを用いた送受話装置を提供することを課題とする。
【０００７】
【課題を解決するための手段】
本発明は、骨伝導スピーカ及び骨伝導マイクを備え、前記骨伝導スピーカの振動面及び骨伝導マイクの振動ピックアップ面がそれぞれ耳介に当接するように形成されたことを特徴とする骨伝導デバイスを用いた送受話装置、を以て上記課題を解決した。
その構成としては、耳介の一部を挟持するタイプ、眼鏡のつるに取り付けるタイプ、頭頂又は首に回るバンドに取り付けるタイプ等が考えられる。
【０００８】
【発明の実施の形態】
本発明に係る送受話装置は、骨伝導スピーカからの振動を聴覚器官に伝達する手段として、また、骨振動をピックアップして送信する手段として、耳介に骨伝導スピーカの振動面並びに骨伝導マイクの振動ピックアップ面を接触させることを特徴とする。その接触は、従来の骨伝導スピーカや骨導マイクのように、圧接状態になっている必要はなく、軽く当接した状態になっていれば十分である。当接させる個所は、耳介のどの部分でもよい。
【０００９】
次に本発明の実施の形態につき、添付図面に依拠して説明する。図１乃至図４は、本発明に係る送受話装置のそれぞれ異なる実施例を示す図である。
【００１０】
本発明にかかる送受話装置は、骨伝導スピーカ１と共に、振動ピックアップ型の骨伝導マイク９を備え、片耳で送受信できるようにしたものである。この場合、骨伝導マイク９からの送信と骨伝導スピーカ１からの受信は、これを接続する通信機器の側で交互に切り替える必要がある。
【００１１】
図１に示す例では、耳介２１の裏側に当接させる骨伝導スピーカ１と、耳介２１の表側の窪み部分に当接させる骨伝導マイク９とが、金属、プラスチック、ゴム等の弾性部材で構成された略Ｕ字形状のクリップ１０を介して配置され、耳介２１を挟み付けるようにして装着される。
【００１２】
図２に示す例は、装着を容易ならしめるために、クリップ部分を洗濯バサミ構造としたもので、クリップ下部にバネつまみ１２を設け、骨伝導マイク９と骨伝導スピーカ１とを開閉可能にしている。この場合、骨伝導マイク９と骨伝導スピーカ１の耳介２１との接触は、前記バネつまみ１２のバネの強さで決定されるため、クリップ部には弾性が不要となるので、クリップ部としていかなる材質のものも使用が可能となり、デザインの自由度が高まる。
【００１３】
図１（Ｂ）は、図１（Ａ）に示す送受話装置の装着状態を示すもので、この場合は骨伝導マイク９（骨伝導スピーカ１の場合もある）が耳介の窪み部分に収まるため、外れにくく、ケーブル１１が引っ張られたり、ランニング等の激しい運動をしたりする場合でも確実な装着が可能となる。また、従来の耳腔内に挿入して使用する骨伝導デバイスと異なり、耳腔を塞がないため装着感が良く、周囲の音を遮蔽することもない。
【００１４】
図３に示すものは、眼鏡のつるの先端部に骨伝導スピーカ１及び骨伝導マイク９（図示してない）を取り付けたものである。骨伝導スピーカ１及び骨伝導マイク９は、それぞれ、眼鏡のつるの先端部に支軸４を設け、それを軸にして回動自在に取り付けてもよいし、眼鏡のつるを弾性材で形成し、その先端部に固定することとしてもよい。
【００１５】
図４に示すものは、耳掛部５を耳に掛けて使用するヘッドバンドタイプであり、バンド部６は、金属、ゴム、プラスチック等の弾性材で形成され、その両端部に耳掛部５が取り付けられる。骨伝導スピーカ１及び骨伝導マイク９（図示していない）は、それぞれ、耳掛部５とバンド部６との接合部の一方又は双方に、支軸７を介して取り付けられた棒材８の先端に設置される。その場合、バンド部６と棒材８間にねじりバネ等を配し、棒材８が常時耳掛部５方向に付勢されるようにすることが好ましい。
【００１６】
上記いずれの例でも、骨伝導スピーカ１及び骨伝導マイク９は従来のように強く圧接させる必要がないため、頭部形状によらず、万人に、痛感がなくて装着感の良い受話装置を提供することができる。しかも、従来の骨伝導スピーカ１より音質がよく、より明瞭、且つ、音量感のある音を実現することができる。これは、本送受話装置の場合は、従来の骨伝導スピーカ１のように振動を直接聴覚器官に伝達するものではなく、耳介自体が振動板となって振動を増幅させるためと考えられる。
【００１７】
【発明の効果】
本発明は上述した通りであって、装着が容易であり、装着感が良くて使用中に痛感を覚えることなく快適に長時間使用することができ、しかも明瞭な音声の送受信が可能で、外部音の聴取にも支障がないといった効果がある。
【図面の簡単な説明】

An earphone generally used as a receiving device transmits sound generated from a sound pressure speaker to a human eardrum by air vibration, and is used in a state where a distal end portion is inserted into an ear canal and the ear canal is closed.
[0003]
When using these types of earphones, the external auditory canal is blocked, making it difficult to hear surrounding sounds, causing danger while driving the vehicle, and unconsciously vocalizing during conversation. There is such a disadvantage. In addition, in a high-temperature and high-humidity environment, the inside of the ear canal becomes stuffy, which causes discomfort and is not preferable in terms of hygiene.
[0004]
As a means for listening to sound without blocking the ear canal, there is a receiver that presses the vibrating surface of the bone conduction speaker against a hard part of the skeleton of the head with constant pressure. When used, there are drawbacks such as painful feeling at the contact surface with the bone conduction speaker and difficulty in hearing sound depending on the angle of contact with the bone conduction speaker. In addition, since there are individual differences in the shape of the head, it is difficult to realize a comfortable wearing feeling for all persons.
[0005]
Further, as an embodiment of this type of receiver, there is a device in which a bone conduction speaker is pressed and fixed to the head, but in this case, a holder surrounding the head is required, which becomes large-scale, It is easily noticeable when worn, and its appearance is not very good.

A spring knob 12 is provided at the lower portion of the clip so that the bone conduction microphone 9 and the bone conduction speaker 1 can be opened and closed. I have. In this case, since the contact between the bone conduction microphone 9 and the pinna 21 of the bone conduction speaker 1 is determined by the strength of the spring of the spring knob 12, the clip portion does not need to have elasticity. Any material can be used, increasing the degree of freedom in design.
[0013]
FIG. 1B shows the wearing state of the transmission / reception device shown in FIG. 1A. In this case, the bone conduction microphone 9 (which may be the bone conduction speaker 1) fits into the recess of the pinna. Therefore, it is hard to come off, and even if the cable 11 is pulled or a heavy exercise such as running is performed, it is possible to securely mount the cable. Further, unlike a conventional bone conduction device that is inserted into the ear cavity and used, the ear cavity is not blocked, so that the feeling of wearing is good and the surrounding sound is not blocked.
[0014]
The thing shown in FIG. 3 has the bone conduction speaker 1 and the bone conduction microphone 9 (not shown) attached to the tip of the temple of the glasses. The bone-conduction speaker 1 and the bone-conduction microphone 9 may each be provided with a support shaft 4 at the tip of the vine of the spectacles, and may be rotatably mounted on the support shaft 4 or may be formed of an elastic material of the vine of the spectacles. , May be fixed to the tip.

Installed at the tip. In that case, it is preferable to arrange a torsion spring or the like between the band portion 6 and the bar member 8 so that the bar member 8 is constantly urged in the direction of the ear hook portion 5.
[0016]
In any of the above examples, since the bone conduction speaker 1 and the bone conduction microphone 9 do not need to be pressed strongly as in the related art, regardless of the shape of the head, a receiving device that has no painful feeling and a good feeling of wearing is provided to everyone. Can be provided. Moreover, the sound quality is better than that of the conventional bone conduction speaker 1, and a clearer sound with a sense of volume can be realized. This is considered to be because, in the case of the present transmitter / receiver, the vibration is not directly transmitted to the hearing organ as in the conventional bone conduction speaker 1, but the auricle itself functions as a diaphragm to amplify the vibration.
[0017]
【The invention's effect】
The present invention is as described above, is easy to wear, has a good feeling of wearing, can be used comfortably for a long time without feeling pain during use, and can transmit and receive clear voice, There is an effect that there is no problem in listening to the sound.
