Description

本発明は、音声の骨伝導を利用する耳装着型の音情報伝達器における耳装着のための補助具であり、その耳からの脱落防止と、マイクロホンを耳甲介腔の下部に適切な圧力で押圧する機能を持った耳装着補助具に関するものである。   The present invention relates to an ear mounting aid in an ear mounted sound information transmitter that uses bone conduction of sound, and prevents the microphone from falling off and an appropriate pressure on the lower part of the concha cavity. It is related with the ear | edge wearing assistance tool with the function to press by.

耳の耳甲介腔部に装着するイヤホン類においては、耳からの脱落防止の手段としてイヤホンの主として外周部にスポンジ製の略円形のリング状の装着補助具を付けるものや、イヤホンを挿入する穴部を有し、外形を耳甲介腔部の形状に模した軟質樹脂製のもの、あるいは実開昭58-104077に記載の単純な形状の弾性突起を有するリング部材をイヤホン外周に装着する形態のもの等がある。また、マイクロホンも含めて耳甲介腔部に挿入するものにおいては、特開2000-261875に見られるようなバネ状の部材をイヤホン部の外周上部に設けて、この先端を耳甲介窩の上側の壁に当ててマイクロホンの所要部への適正な押圧を得るものがある。   For earphones to be attached to the concha cavity of the ear, a device that attaches a substantially circular ring-shaped attachment aid made of sponge to the outer periphery mainly of the earphone as a means for preventing the ear from falling off, or insert an earphone A ring made of a soft resin having a hole and having an outer shape imitating the shape of the concha cavity, or a ring member having a simple elastic protrusion described in Japanese Utility Model Publication No. 58-104077 is attached to the outer periphery of the earphone. There are some forms. In addition, in the case of inserting into the concha cavity part including the microphone, a spring-like member as seen in Japanese Patent Laid-Open No. 2000-261875 is provided on the outer periphery of the earphone part, and this tip is attached to the concha fossa. There is one which obtains an appropriate pressure to a required portion of the microphone by hitting the upper wall.

一方、ＩＣ化、デジタル通信技術の進歩により、イヤホンとマイクロホン部を耳に装着するだけではなく、これらの入出力信号を処理し制御する回路、および電池も含めて耳部に装着する形態が可能となってきている。しかし、耳甲介腔部挿入する部分に全てを収めるにはまだ大きすぎることもあり、イヤホンとマイクロホン部を耳甲介腔部に収めて、電池と信号処理回路などは耳の外側に位置するように一体とした形態が主となっている。このような形態に於いては、比較的重量もあり大きな部分が装着部の外側になるため、重力による脱落方向の回転モーメントが働くため耳への装着安定性をよりよくすることが必要であると共に、骨伝導振動をより大きなレベルでマイクロホンにて拾うために、マイクロホン部を耳甲介腔の下部に適切な圧力で当てる必要がある。   On the other hand, with the advancement of IC and digital communication technology, it is possible not only to put earphones and microphones on the ear, but also to put them on the ears, including circuits that process and control these input and output signals, and batteries. It has become. However, it may still be too large to fit all into the concha cavity insertion part, the earphone and microphone part are housed in the concha cavity, and the battery and signal processing circuit etc. are located outside the ear The integrated form is the main. In such a configuration, the weight is relatively large and a large part is outside the wearing part, and therefore a rotational moment in the drop-out direction due to gravity works, so it is necessary to improve the wearing stability to the ear. At the same time, in order to pick up the bone conduction vibration with a microphone at a higher level, it is necessary to apply the microphone part to the lower part of the concha cavity with an appropriate pressure.

従来の補助具の形態では脱落し易い、あるいはマイクロホンの適切な押圧力が得られないなど、本形態の音情報伝達器での補助具としての十分な機能が得られない状況にある。また、耳の形状と大きさは千差万別であり、広い範囲の耳形状の相違に対応することも十分ではない。   In the form of the conventional assisting device, it is easy to drop off, or an appropriate pressing force of the microphone cannot be obtained, so that a sufficient function as an assisting device in the sound information transmitter of this embodiment cannot be obtained. In addition, the shape and size of the ears vary widely, and it is not sufficient to cope with a wide range of ear shape differences.

本発明は、耳への装着性を維持すると共に、脱落しにくく、マイクロホンを耳甲介腔の下部に適正な圧力で押圧することを、耳の大きさ形状の多様性に対して実現する耳装着補助具を提供することを目的とする。   The present invention is an ear that maintains wearability to the ear, is hard to drop off, and that presses the microphone to the lower part of the concha cavity with an appropriate pressure for a variety of ear sizes and shapes. An object is to provide a wearing aid.

本発明にかかる耳装着補助具は、本体装置への取り付けを容易にし複数種の補助具の交換使用を容易にするとともに、耳形状の多様性に対して脱落し難く装着安定性に最も寄与する手段として、耳珠の内側から外耳道口に至る部分に当てる突起部を設けて、さらに、この突起部が耳の形状の多様性に対して有効に作用するように主として耳甲介腔および耳甲介窩部分の大きさの違いに柔軟に変形するドーム形状の弾性部を形成し脱落防止を計るとともに、このドーム状弾性部でマイクロホンの耳甲介腔の下部への適切な押圧も得るようにする。   The ear wearing aid according to the present invention facilitates the attachment to the main body device, facilitates the replacement use of a plurality of types of assisting devices, and contributes most to wearing stability because it is difficult to drop off due to the variety of ear shapes. As a means, there is provided a protrusion to be applied to the part from the inside of the tragus to the ear canal mouth, and the protrusion is mainly used to effectively act on the diversity of the shape of the ear. A dome-shaped elastic part that deforms flexibly depending on the size of the axillary part is formed to prevent falling off, and this dome-shaped elastic part also obtains an appropriate pressure on the lower part of the concha cavity of the microphone To do.

また、ドーム形状を重ねて形成し、使用者がそのドーム形状のひとつをカッター等で切り取ることにより、より多種類の大きさのドーム状部を持つ耳装着補助具を得られるようにする。   In addition, the dome shape is formed so as to overlap, and the user cuts one of the dome shapes with a cutter or the like, so that an ear wearing aid having a larger variety of dome-shaped portions can be obtained.

耳の形状、大きさの多様性に対して、音情報伝達器の耳への装着の安定性と、マイクロホンの耳甲介腔の下部への適切な押圧力を得ることが出来、快適な音情報伝達器の使用に寄与することが出来る     Comfortable sound with a variety of ear shapes and sizes, with the ability to secure the sound information transmitter to the ear and the appropriate pressure on the lower part of the concha cavity of the microphone.

本発明にかかる耳装着補助具について説明する。
図1は、本実施の形態の耳装着補助具を装着する音情報伝達器において、耳装着補助具を付ける前の外観形状を示すものである。図2は耳装着補助具を音情報伝達器に取り付けた状態を示す図である。図3、図4、図5、図6は耳の形状の多様性に対応するため準備する複数種の耳装着補助具の外観を示すものである。 The ear wearing aid according to the present invention will be described.
FIG. 1 shows an external appearance of the sound information transmitter to which the ear wearing aid of the present embodiment is attached before the ear wearing aid is attached. FIG. 2 is a view showing a state in which the ear wearing aid is attached to the sound information transmitter. 3, FIG. 4, FIG. 5, and FIG. 6 show the appearance of a plurality of types of ear wearing aids prepared to cope with the variety of ear shapes.

図１および図２において、音情報伝達器Aのイヤホン部８の円筒部外周に耳装着補助具４のリング状部ｈが勘合し、円筒部の外周両側に突き出た矩形の突起1と突起2は耳装着補助具４の角穴ｃと角穴ｄと勘合するようになされている。耳装着補助具は軟質樹脂またはゴム状材質で出来ていて、取り付け時に必要な伸縮性を有していると共に、ドーム状部ｂはその形状効果で略矢印ｅ方向からの押圧に対して大きく変形する柔軟性を有している。突起部ａは耳珠の内側面から外耳道口にかけての部分に接触するようになる部分であり、柔軟性を有しているが、その形状よりドーム状部ｂほどの柔軟性は無い。   1 and 2, the ring-shaped portion h of the ear mounting aid 4 is fitted to the outer periphery of the cylindrical portion of the earphone portion 8 of the sound information transmitter A, and the rectangular protrusion 1 and the protrusion 2 projecting on both sides of the outer periphery of the cylindrical portion. Is adapted to fit into the square hole c and the square hole d of the ear wearing aid 4. The ear wearing aid is made of a soft resin or rubber-like material, and has elasticity necessary for attachment, and the dome-like portion b is largely deformed by pressing from the direction of the arrow e due to its shape effect. Have the flexibility to The protrusion a is a portion that comes into contact with the portion from the inner side surface of the tragus to the mouth of the ear canal, and has flexibility, but is not as flexible as the dome-shaped portion b because of its shape.

図4の耳装着補助具４を音情報伝達器Ａに取り付けた図2に示す状態は、右耳に装着する場合の状態であるが、耳装着補助具４を左右反転して音情報伝達器Aに取り付けると突起部ａの方向が反対となり、左耳への装着用になる。このように、機能を損なうことなく左右両耳への装着に対応できるようになされている。   The state shown in FIG. 2 in which the ear wearing aid 4 of FIG. 4 is attached to the sound information transmitter A is a state in which the ear wearing aid 4 is worn on the right ear. When attached to A, the direction of the protrusion a is opposite, and it is for wearing on the left ear. In this way, it can be adapted to be worn on the left and right ears without impairing the function.

図2の状態で右耳に装着した場合、突起部ａは耳珠の内側面に当たり、角穴ｃ側のリング状部が対珠の内側に入る。ドーム状部ｂは耳甲介腔部から耳甲介窩部にかけて収まり、特に上部は対輪と耳甲介窩部の境の壁に当たり、耳と耳装着補助具のドーム状部ｂの大きさとの関係で合わない分ドーム状部ｂが変形することにより、マイクロホン7の耳甲介腔の下部への押圧力を与える機能を成す。   When mounted on the right ear in the state of FIG. 2, the protrusion a hits the inner surface of the tragus, and the ring-shaped portion on the side of the square hole c enters the inside of the antipod. The dome-shaped portion b fits from the concha cavity portion to the concha fossa portion, and particularly the upper portion hits the wall between the paired wheel and the concha fossa portion, and the size of the dome-shaped portion b of the ear and the ear fitting aid The dome-shaped part b is deformed by the amount that does not fit in the above relationship, thereby providing a function of applying a pressing force to the lower part of the concha cavity of the microphone 7.

ドーム状部ｂの大きさを変えたものや、ドーム状部を重ねたものが図3から図6に示すものである。図３および図４は、ドーム状部ｂの高さの異なる形状としたものである。   FIGS. 3 to 6 show the dome-shaped portion b having a different size and the dome-shaped portion overlapped. 3 and 4 show shapes in which the height of the dome-shaped portion b is different.

図5や図6に示すものは外側のドーム状部をその根元部分で切り離すと、大きさの変わった新たな耳装着補助具として使用できる形態になる。   5 and 6 can be used as a new ear wearing aid having a different size when the outer dome-shaped portion is cut off at the base portion.

対珠が大きく開いていて角穴ｃ近傍のリング部が対珠の内側に引っかかるような状態にならない場合や、耳珠より対輪までの距離が大きな耳の場合は、図６の耳装着補助具6のタイプを交換し使用することにより、突起部ａに相当する部分が耳珠の内側部分から離れてしまい、イヤホン部8とマイクロホン7が耳甲介腔部に引っかからずに脱落する、あるいは安定しないことを防ぐことが出来る。   If the pearl is wide open and the ring part near the square hole c does not get caught inside the pearl, or if the ear is far away from the pearl By exchanging and using the type of the tool 6, the portion corresponding to the protrusion a is separated from the inner part of the tragus, and the earphone 8 and the microphone 7 fall off without being caught in the concha cavity, or It can be prevented from becoming unstable.

また、耳甲介腔部から耳甲介窩部の部分が小さい耳の場合は図６の耳装着補助具５、更に小さい場合には耳装着補助具５の外側のドーム状部ｆを切り取り、内側のドーム状部ｇでこれを代用するなどの使い分けをして、耳の形状と大きさの多様性に対応できる。   Further, in the case where the portion of the concha cavity portion from the concha cavity portion is small, the ear wearing aid 5 in FIG. 6 is cut out, and when it is smaller, the outer dome-shaped portion f of the ear wearing aid 5 is cut out. The inner dome-shaped portion g can be used as a substitute, and can cope with a variety of ear shapes and sizes.

各個人により耳の形状と大きさはいろいろであるので図3から図6に示す耳装着補助具を一式として音情報伝達器に添付して提供する。こうすることにより、その交換は何の道具も要らない取り付け構造であるので、使用者が自分の耳の状況に応じた交換使用が出来、使用者の利便性の向上を図ることが可能となる。   Since each person has various shapes and sizes of ears, the ear wearing aids shown in FIGS. 3 to 6 are provided as a set attached to the sound information transmitter. By doing so, since the replacement is a mounting structure that does not require any tools, the user can use the replacement according to the situation of his / her ear, and the user's convenience can be improved. .
