Abstract
Receivers in conventional transmitter/receivers had the defect of unclear acoustics. The purpose of the present invention is to provide a receiver capable of clear acoustics. Sound waves from a sound-emitting body are effectively transmitted to the eardrum, by setting the incident angle relative to a head cross-section in the sound wave radiation axis of the sound-emitting body used in a transmitter/receiver to greater than 0° and less than 90° or by using a plurality of sound-emitting bodies having sound wave radiation axes of different incident angles. Alternatively, when a plurality of sound-emitting bodies are provided, one sound-emitting body among the plurality of sound-emitting bodies is arranged such that the incident angle relative to the auricular-abutting surface in the sound wave radiation axis for said sound-emitting body is greater than 0° and less than 90° and such that the sound wave radiation axis or the next sound wave radiation axis for all sound-emitting bodies other than the one sound-emitting body is orthogonal to the sound wave radiation axis or the next sound wave radiation axis for the one sound-emitting body.
Description
本発明は、耳介に当接させて使用する受話器と、これを用いた送受話器に関する。
The present invention relates to a handset used in contact with an auricle and a handset using the handset.
耳介に当接させて聴音する受話器において、受話器の音質改善のための提案がなされている（例えば下記特許文献１参照。）。しかしながら、かかる従来の受話器における聴音の音質の改善は十分とはいえない。
In a handset that abuts on the auricle and listens, a proposal for improving the sound quality of the handset has been made (for example, see Patent Document 1 below). However, it cannot be said that the sound quality of the listening sound in such a conventional handset is sufficiently improved.
図１は、音波放射軸の概念を説明するための図であり、音の電気信号を音波に変換する発音体１０（例えばスピーカー等）の中心と、発生した音波の進行方向での音波の中心とを結ぶ軸を音波放射軸１１と称し、矢印は音波の進む方向を示している。また、音波放射軸１１と反対方向へ伸ばした軸を、便宜上、後音波放射軸１２と称する。
FIG. 1 is a diagram for explaining the concept of a sound wave radiation axis, and the center of a sounding body 10 (for example, a speaker) that converts an electrical signal of sound into sound waves, and the center of sound waves in the traveling direction of the generated sound waves. The axis connecting the two is called the sound wave radiation axis 11, and the arrow indicates the direction in which the sound wave travels. Further, an axis extending in the direction opposite to the sound wave radiation axis 11 is referred to as a rear sound wave radiation axis 12 for convenience.
図２は、一般的に用いられている送受話器を示す図であり、（ａ）は外観斜視図を示している。図２（ａ）において、２１は受話器を使用する際の耳介に当接する面を表し、これを耳介当接面と称する。なお、２２は音波を放射する受話口、２３は送話口（マイク）である。
また、図２（ｂ）は、耳介当接面２１のみを拡大して耳介当接面２１と、受話口から放射される音波の音波放射軸２４との位置関係を示した図である。音波放射軸２４と耳介当接面２１とのなす角度を音波放射軸当接面角度といい、これをθで表すこととする。後述のように、従来の音波放射軸当接面角度θは９０度であった。 FIG. 2 is a diagram showing a handset that is generally used. FIG. 2A is an external perspective view. In FIG. 2A,reference numeral 21 denotes a surface that comes into contact with the auricle when the handset is used, and this is referred to as an auricle contact surface. In addition, 22 is an earpiece which radiates | emits a sound wave, 23 is a mouthpiece (microphone).
FIG. 2B is a diagram showing the positional relationship between thepinna contact surface 21 and the sound wave radiation axis 24 of the sound wave emitted from the earpiece by enlarging only the pinna contact surface 21. . The angle formed by the sound wave radiation axis 24 and the auricle contact surface 21 is referred to as the sound wave radiation axis contact surface angle, and this is represented by θ. As will be described later, the conventional sound wave radiation axis contact surface angle θ was 90 degrees.
また、図２（ｂ）は、耳介当接面２１のみを拡大して耳介当接面２１と、受話口から放射される音波の音波放射軸２４との位置関係を示した図である。音波放射軸２４と耳介当接面２１とのなす角度を音波放射軸当接面角度といい、これをθで表すこととする。後述のように、従来の音波放射軸当接面角度θは９０度であった。 FIG. 2 is a diagram showing a handset that is generally used. FIG. 2A is an external perspective view. In FIG. 2A,
FIG. 2B is a diagram showing the positional relationship between the
図３は、従来の送受話器の使用時における音波放射軸１１の、耳介３０に対する位置関係を示した図である。図３（ａ）は、実際の使用時において、送話口２３を口元に近づけて傾けることによって、音波放射軸１１が耳介３０の上部方向へ傾くことになることを示している。
受話器は、発音体から放射された音波を耳介３０に反射させて鼓膜へ到達させる構造となっている為、耳介３０の上部へ放射された音波の一部は、一旦耳介３０の上部で反射するため、外耳道口より遠ざかる方向へ反射してしまい（図３（ａ）の矢印１３参照。）、有効に鼓膜へ到達せずに結果として明瞭な聴音が困難となる原因の１つとなっている。 FIG. 3 is a diagram showing a positional relationship of the soundwave radiation axis 11 with respect to the auricle 30 when the conventional handset is used. FIG. 3A shows that, in actual use, the sound wave emission axis 11 is tilted in the upper direction of the auricle 30 by tilting the mouthpiece 23 close to the mouth.
Since the receiver has a structure in which sound waves radiated from the sounding body are reflected on theauricle 30 and reach the eardrum, a part of the sound waves emitted to the upper part of the auricle 30 is once on the upper part of the auricle 30. Therefore, it is reflected in the direction away from the ear canal mouth (see the arrow 13 in FIG. 3 (a)). ing.

本発明は、上述のような問題に鑑みなされたものであり、送受話器に使用される受話器の聴音の音質を改善することを目的とするものである。
The present invention has been made in view of the above-described problems, and aims to improve the sound quality of the listening sound of a handset used for a handset.
本発明は、送受話器に用いる受話器に関し、本発明の上記目的は、該受話器は発音体を備え、前記発音体の音波放射軸の耳介当接面に対する入射角が、０度より大きく９０度より小さくなるように、前記発音体を配設したことを特徴とする受話器によって達成される。
The present invention relates to a handset used in a handset. The above object of the present invention is to provide a handset that has a sounding body, and the incident angle of the sounding body with the sound wave radiation axis of the sounding body relative to the auricle contact surface is greater than 0 degree and 90 degrees This is achieved by a handset characterized in that the sounding body is arranged to be smaller.
また、本発明は、送受話器に用いる受話器に関し、本発明の上記目的は、該受話器は複数の発音体を備え、前記複数の発音体のうちの一つの発音体の音波放射軸の耳介当接面に対する入射角が０度より大きく９０度より小さい角度になるように該発音体を配設し、前記一の発音体を除く全ての前記発音体の音波放射軸又は後音波放射軸が前記一の発音体の音波放射軸又は後音波放射軸と交差するように配設したことを特徴とする受話器によって達成される。
The present invention also relates to a handset for use in a handset. The above object of the present invention is to provide a handset that includes a plurality of sounding bodies, and that uses a sound radiation axis of one sounding body among the plurality of sounding bodies. The sounding body is arranged so that the incident angle with respect to the tangent surface is larger than 0 degree and smaller than 90 degrees, and the sound wave radiating axes or the back sound wave radiating axes of all the sounding bodies except the one sounding body are This is achieved by a receiver characterized in that it is arranged so as to intersect with the sound wave emission axis or the back sound wave emission axis of one sounding body.
さらに、本発明の上記目的は、前記発音体の外周縁どうしの距離を１０ｍｍ以下とすることによって効果的に達成される。
Furthermore, the above object of the present invention is effectively achieved by setting the distance between the outer peripheral edges of the sounding body to 10 mm or less.

According to the handset according to the present invention, it is possible to provide a handset that can be heard clearly and a handset using the handset.
図４は、本発明に係る送受話器の使用時における音波放射軸の、耳介に対する位置関係を示した図である。図４（ａ）は本願の送受話器使用時の受話口の発音体の音波放射軸１１の位置を示す図であり、図４（ｂ）に示すごとく、発音体１０の音波放射軸１１が発音体を１０収めた受話口の耳介当接面２１に対してなす角度をθとしたとき、θを０度より大きく９０度より小さくなるように発音体１０を配設することで、送受話器使用時においても耳介に対して音波放射軸が上向きとならない様にすることができる。
FIG. 4 is a diagram showing the positional relationship of the sound wave radiation axis with respect to the pinna when using the handset according to the present invention. FIG. 4A is a diagram showing the position of the sound radiation axis 11 of the sound generator of the earpiece when the handset of the present application is used. As shown in FIG. 4B, the sound radiation axis 11 of the sound generator 10 produces sound. By arranging the sounding body 10 so that θ is larger than 0 degree and smaller than 90 degrees when θ is an angle formed with respect to the pinna contact surface 21 of the earpiece containing 10 bodies, the handset It is possible to prevent the sound wave emission axis from being directed upward with respect to the pinna even during use.
また、この耳介へ到達する反射された音波の反射効率を上げれば、発音体を複数とすることで明瞭度の向上効果が顕著となる。即ち、複数の各発音体の音波放射軸あるいは後音波放射軸が交差するように発音体を受話器の受話口に配設すれば、同一方向からの反射音波のみではなく、多方向からの反射音波が外耳道口に到達するため、より明瞭な受音が可能となる。すなわち、複数の発音体の場合、一の発音体（後述の直接音担当の発音体）の音波放射軸と耳介当接面とのなす角度θが０度より大きく９０度より小さくなるように当該発音体を配設し、当該発音体を除く全ての発音体の音波放射軸又は後音波放射軸が前述の一の発音体の音波放射軸又は後音波放射軸と交差するように配設する。
これに対して、従来の受話器においては、発音体を複数としても音量が大きくなるだけで明瞭度の向上は期待できなかった。 Further, if the reflection efficiency of the reflected sound wave that reaches the pinna is increased, the effect of improving the intelligibility becomes remarkable by using a plurality of sounding bodies. That is, if the sounding body is arranged at the earpiece of the receiver so that the sound wave emission axes or the back sound wave emission axes of a plurality of sounding bodies intersect, not only the reflected sound waves from the same direction but also the reflected sound waves from multiple directions. Can reach the ear canal mouth, so that clearer sound reception is possible. That is, in the case of a plurality of sounding bodies, the angle θ formed by the sound wave emission axis of one sounding body (a sounding body in charge of direct sound described later) and the auricle contact surface is larger than 0 degree and smaller than 90 degrees. The sounding body is arranged, and the sound wave emitting axis or the post sound wave emitting axis of all sounding bodies except the sounding body is arranged so as to intersect the sound wave emitting axis or the rear sound wave emitting axis of the one sounding body. .
On the other hand, in the conventional handset, even if a plurality of sounding bodies are used, the volume is increased and the improvement of the intelligibility cannot be expected.

発音体を駆動する音信号を遅延処理装置にて所定時間の遅延音信号を生成して発音体を駆動するアンプを遅延時間生成装置付きアンプと称すると、この複数の発音体を有する受話器において、少なくとも１つの発音体を直接音担当とし、その他の発音体を間接音担当として、遅延時間生成装置付きアンプで駆動すれば、遅延音声信号で駆動された発音体から放射される音波は、鼓膜へ伝達されたときに間接音として知覚され、間接音効果によってより自然な聴音が可能となる。
複数の発音体を使用する受話器においては、受話器を耳介に当接して使用する際に、地上から高い方に位置する発音体が前方から音波を放射するため、これを直接音担当とし、その他の発音体を間接音担当とすれば、より自然な聴音が可能となる。
受話器使用時において、左右どちらの手で受話器を保持した場合であっても地上から最も高い位置にある方の発音体を直接音担当とするように切り替える必要があるため、例えば、受話器の傾き等を検出して左右どちらの手で受話器が保持されて耳介に当接されているのかを判定する位置検出装置により、その時に高い位置にある方の発音体を検出して、そこから直接音を放射し、残りの発音体を遅延時間生成装置付きアンプで駆動する受話器とすれば、より自然な聴音が可能となる。 When a sound signal for driving a sounding body is generated by a delay processing device to generate a delayed sound signal for a predetermined time and an amplifier for driving the sounding body is referred to as an amplifier with a delay time generating device, the receiver having the plurality of sounding bodies, If at least one sounding body is in charge of direct sound and the other sounding bodies are in charge of indirect sound and is driven by an amplifier with a delay time generator, sound waves emitted from the sounding body driven by the delayed sound signal are transmitted to the eardrum. When transmitted, it is perceived as an indirect sound, and the indirect sound effect enables a more natural listening sound.
In a handset that uses multiple sounding bodies, when the handset is used in contact with the auricle, the sounding body located higher from the ground radiates sound waves from the front, so this is directly responsible for sound, and others If the sounding body is in charge of indirect sound, a more natural listening sound is possible.
When using the handset, even if the handset is held with either the left or right hand, it is necessary to switch so that the sounding body at the highest position from the ground is in charge of the sound directly. The position detection device that detects whether the handset is held by the left or right hand and is in contact with the auricle, detects the higher sounding body at that time, and directly produces sound from it. If the receiver is driven by an amplifier with a delay time generator, the natural sound can be heard.
