本発明は、耳介の耳甲介腔の凹部に収納されて装着して
使用される耳介装着型の電気音響変換器に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an auricle-mounted electroacoustic transducer that is used by being housed in a recess in the concha cavity of the auricle.
従来、耳介装着型の電気音響変換器として、第６図及び
第７図に示すように構成されたものが知られている。2. Description of the Related Art Conventionally, as an auricle-mounted electroacoustic transducer, one configured as shown in FIGS. 6 and 7 is known.
第６図に示すものは、耳介装着型のイヤホンであって、
このイヤホンは、振動板を含む電、気音響変換素子を内
蔵したイヤホン本体１の一端面に音道２を形成した耳介
挿入部３を突設し、この耳介挿入部３を耳介の耳甲介腔
に連続するさらに内方の外耳道にまで挿入して耳介に装
着するように構成されてなるものである。What is shown in FIG. 6 is a pinna-mounted earphone,
This earphone has an auricle insertion section 3 with a sound path 2 formed therein protruding from one end surface of an earphone body 1 which has a built-in electro-air acoustic transducer element including a diaphragm. It is configured to be inserted into the external auditory canal further inward, which is continuous with the concha cavity, and attached to the auricle.
また、第７図に示すものは、ステレオ再生の聴取を行い

耳道にまで挿入して耳介に装着するように構成されてな
るものである。Furthermore, in the one shown in FIG. 7, a pair of earphones 4.5 are connected by a connecting rod 6 so that stereo reproduction can be performed. The one shown in FIG. 7 also includes each earphone 4.
, 5, an earphone body 1 having a protruding auricle insertion part 3 with a sound path 2 formed on one end surface, and configured to be inserted into the ear canal and attached to the auricle. It is something that has been done.
上述したような第６図及び第７図に示すものは、いずれ
も耳介挿入部３を外耳道まで挿入して装着するものであ
るため、装着時の圧迫感を免れない。In both of the devices shown in FIGS. 6 and 7 as described above, the auricle insertion portion 3 is inserted into the external auditory canal to be worn, so a feeling of pressure cannot be avoided when the device is worn.
また、外耳道に押し込む程度により上記外耳道等に痛み
や違和感を強く感する。さらに、再生音質の劣化も避け
られない。Furthermore, depending on the extent to which the device is pushed into the external auditory canal, pain or discomfort may be felt strongly in the external auditory canal. Furthermore, deterioration in playback quality is also unavoidable.
このようなイヤホンが有している問題点の解消を図るた
め、第８図に示すようにスピーカ６の一側面に圧着パッ
ド７を設けるとともに耳掛は用の弾性を有する湾曲した
弦８を設けたものが提案されている。この耳掛は式のイ
ヤホンは、圧着パッドを耳介の外側に圧着させ、弦８を
上記耳介の外周に引掛けて使用される。In order to solve the problems that such earphones have, as shown in FIG. 8, a crimp pad 7 is provided on one side of the speaker 6, and a curved string 8 with elasticity is provided for the ear hook. Something has been proposed. This hook-on type earphone is used by pressing a pressure pad onto the outside of the auricle and hooking the string 8 around the outer periphery of the auricle.
しかし、上記耳掛は式のものにあっては、前述したよう
な耳介挿入部を外耳道まで挿入して装着するものが有し
ている問題点の解消を図ることはできるが、装着した状
態が不安定であり、良好な装着状態が得られないばかり
か、耳介に対する装着位置によっては再生音質の劣化を
生じさせてしまう。However, if the above-mentioned ear hook is of the type type, it is possible to solve the problem of those that are worn by inserting the auricle insertion part into the ear canal as described above, but is unstable, and not only is it not possible to obtain a good wearing condition, but depending on the mounting position with respect to the auricle, the reproduced sound quality may deteriorate.
また、弾性を有するヘッドバンドの両端に一対のスピー

スピーカを耳介に圧着して使用するヘッドホンか広く用
いられているが、このヘッドホンにあっては、ヘッドバ
ンドの弾性力による頭部の圧迫感を生じ、装着時の不快
感を避けることができない。In addition, headphones are widely used in which a pair of speakers are attached to both ends of an elastic headband, and the speakers are pressed to the auricle using the elastic force of the headband. In this case, the elastic force of the headband creates a feeling of pressure on the head, making it unavoidable to feel uncomfortable when wearing the headband.
このような問題点の解消を図るため、電気音響変換素子

よって、外耳道に圧迫感を与えることなく、頭部への圧
迫感を与えることなく良好な装着感をもって装着し得る
電気音響変換器を構成することができる。In order to solve these problems, the outer casing containing the electroacoustic transducer was shaped so that it could be stored in the recess of the concha cavity, so that when it was stored in the recess of the concha cavity, it would not face the tragus of the ear. By forming the outer casing so as to be supported by the beads, and by forming the sound emitting surface side of the outer casing in front of the electroacoustic transducer element into a uniformly curved surface, there is no feeling of pressure on the ear canal, and there is no feeling of pressure on the head. Therefore, it is possible to construct an electroacoustic transducer that can be worn with good wearing comfort without giving any discomfort.

凹部に収納されるものであるため、耳甲介腔の凹部の一

音響変換素子から放音される再生音か耳甲介腔の凹部に
よって反射させられるなどして再生音の歪を生じさせ、
再生音質の劣下を招いてしまう。By the way, as mentioned above, in the case of an electroacoustic transducer that is configured to be housed and worn in the recess of the concha cavity, the entire outer casing that constitutes the main body of the device is inserted into the concha cavity when worn. Since it is housed in a recess, it is extremely difficult to attach it to a fixed position in the recess of the concha cavity. For example, the device may be installed at an angle in the recess of the concha cavity, and the sound emitting surface may no longer face the external auditory canal where the eardrum is located. If the sound emitting surface is worn without facing the ear canal, the reproduced sound emitted from the electroacoustic transducer will be reflected by the concave part of the concha cavity, causing distortion of the reproduced sound.
This will lead to deterioration in playback quality.
また、電気音響変換素子からの再生音が耳甲介腔の凹部
によって反射させられるなどして外耳道に直接放音され
ないと、再生音源位置が不安定となり、良好な再生音の
聴取か行えなくなってしまう。In addition, if the reproduced sound from the electroacoustic transducer is not emitted directly into the ear canal due to reflection from the concave part of the concha cavity, the position of the reproduced sound source becomes unstable and it becomes impossible to listen to the reproduced sound properly. Put it away.

る。SUMMARY OF THE INVENTION Therefore, the present invention provides an electroacoustic transducer configured to be housed and worn in a recess in the concha cavity, which can be installed in the concave cavity at a constant position at all times. To provide an electro-acoustic transducer that enables the user to listen to good reproduced sound without deteriorating the quality of reproduced sound by emitting the reproduced sound from a conversion element directly into the ear canal. It was proposed for this purpose.

きる。As described above, the electroacoustic transducer according to the present invention can be mounted in the concave part of the concha cavity with a fixed mounting position because the mounting position is regulated in the concave part of the concha cavity. Since the center of the transducer element and the center of the external auditory canal ostium are approximately aligned, the reproduced sound from the electroacoustic transducer element is emitted directly into the external auditory canal, and unnecessary reflected sound within the recess of the concha cavity is prevented. By preventing the occurrence of such occurrence, it is possible to always listen to good reproduced sound without causing deterioration in the quality of reproduced sound.

器。[Scope of Claims] Contains an electroacoustic transducer and is formed in a shape that can be stored in a recess in the concha cavity between the tragus and antitragus of the auricle, and is stored in the recess in the concha cavity. an outer casing configured to be supported by the tragus and the opposite tragus when the outer casing is placed in the concha cavity; and a cord lead-out portion for an external connection cord of the electroacoustic transducer, the outer casing being housed in a recess in the concha cavity, and the cord lead-out portion being connected to the tragus of the auricle. The electroacoustic transducer is configured such that the center of the electroacoustic transducer element and the center of the external auditory canal ostium substantially coincide with each other by contacting the auricle at a position below the tragus.
