Description

本発明は、音楽再生機能を有する携帯電話機でのステレオによる臨場感のある音楽再生とハンズフリーでありながら周囲の雑音などに影響を受けない明瞭な通話を実現するリモコン付きステレオイヤホンマイクに関する。   The present invention relates to a stereo earphone / microphone with a remote control that realizes a realistic music reproduction by a stereo in a mobile phone having a music reproduction function and a clear call that is hands-free and is not affected by ambient noise.

従来、リモコン付きステレオイヤホンマイクは２つのイヤホン本体と携帯電話機とを接続するケーブル上にフックスイッチを設けたリモコンがあり、そのリモコンにマイクロホンを搭載したものが主流である（特許文献１参照）。
特開平５−９１５８４号公報 Conventionally, a stereo earphone / microphone with a remote control has a remote control in which a hook switch is provided on a cable connecting two earphone bodies and a mobile phone, and a microphone is mounted on the remote control (see Patent Document 1).
JP-A-5-91584

従来のリモコン付きステレオイヤホンマイクでは、通話時にマイクロホンが音声と一緒に周囲の雑音や風雑音を拾ってしまうとともに、衣服などがリモコンに擦れて雑音も入ってしまうため、相手方が聞き取りにくいという問題があった。   With conventional stereo earphone / microphone with remote control, the microphone picks up ambient noise and wind noise along with the voice during a call, and the clothes are rubbed into the remote control and noise enters, which makes it difficult for the other party to hear. there were.

本発明は上記の問題に鑑みてなされたもので、リモコン付きステレオイヤホンに耳内に発生する音声のみを拾うようにマイクロホンを搭載してリモコン付きステレオイヤホンマイクとし、音楽再生機能を有する携帯電話機でのステレオによる臨場感のある音楽再生とハンズフリーでありながら周囲の雑音などに影響を受けない明瞭な通話を実現できるリモコン付きステレオイヤホンマイクを提供することを目的とする。   The present invention has been made in view of the above problems, and a stereo earphone / microphone with a remote control is mounted on a stereo earphone with a remote control so that only the sound generated in the ear is picked up. It is an object to provide a stereo earphone / microphone with a remote control that can realize a clear voice call that is not affected by ambient noise and the like while being hands-free and playing music with a sense of reality.

上記目的を達成するため本発明は、音楽再生機能を有する携帯電話機に接続し使用するリモコン付きステレオイヤホンマイクであって、耳の穴に差し込む型の２つのイヤホン本体の一方又は両方にマイクロホンを組み込み、リモコンに、２つのイヤホン用スピーカのみを動作させるステレオイヤホンモードと、１つのマイクロホンを動作させ、かつ、マイクロホンが動作している方のイヤホン用スピーカは動作させず、他方のイヤホン用スピーカを動作させるイヤホンマイクモードとに切り替える切替スイッチを設けたことを特徴とするものである。   In order to achieve the above object, the present invention is a stereo earphone / microphone with a remote control that is used by connecting to a mobile phone having a music playback function, and a microphone is incorporated in one or both of two earphone bodies that are inserted into the ear holes. , Stereo earphone mode to operate only two earphone speakers on the remote control, one microphone to operate, and the other earphone speaker to operate without operating the other earphone speaker The present invention is characterized in that a changeover switch for switching to the earphone microphone mode to be provided is provided.

上記構成を有する本発明において、２つのイヤホン本体の両方にマイクロホンを組み込む場合、リモコンに、イヤホンマイクモードに切り替えたときにどちらのイヤホン用スピーカを使用するかを選択するための選択スイッチを設けることが望ましい。また、リモコンに設けられているフックスイッチを切替スイッチとして使用し、フックスイッチをオン（オンフック／終話状態）にすることでステレオイヤホンモードにし、フックスイッチをオフ（オフフック／受話状態）にすることでイヤホンマイクモードにすることが望ましい。さらに、マイクロホンを組み込むイヤホン本体にさらに第２のマイクロホンを組み込み、第２のマイクロホンはそれを組み込むイヤホン本体を耳に装着したときに耳外の音を拾うことが望ましい。   In the present invention having the above configuration, when a microphone is incorporated in both of the two earphone main bodies, a selection switch for selecting which earphone speaker to use when switching to the earphone microphone mode is provided on the remote controller. Is desirable. Also, use the hook switch provided on the remote control as a changeover switch, turn on the hook switch (on-hook / end call state) to switch to stereo earphone mode, and turn off the hook switch (off-hook / listening state) It is desirable to use the earphone microphone mode. Further, it is desirable that a second microphone is further incorporated in the earphone body into which the microphone is incorporated, and the second microphone picks up sounds outside the ear when the earphone body into which the microphone is incorporated is attached to the ear.

上記本発明によれば、マイクロホンを直接イヤホン本体に組み込むから、イヤホンマイクモードに切り替えたときに周囲の雑音などを拾うことなく耳内に発生する音声のみを拾うことができるようになり、相手方が聞き取りやすくなる。こうして、音楽再生機能を有する携帯電話機でのステレオによる臨場感のある音楽再生とハンズフリーでありながら周囲の雑音などに影響を受けない明瞭な通話を実現できる。また、イヤホンマイクモードではマイクロホンが動作している方のイヤホン用スピーカは動作させず、他方のイヤホン用スピーカを動作させる（同じイヤホン本体に組み込んでいるイヤホン用スピーカとマイクロホンは同時に動作させない）から、エコーが発生せず、相手方がより聞き取りやすくなるとともに、複雑なエコーキャンセラー構造や回路が不要となる。こうして、コストを抑えながら、より明瞭な通話を実現できる。   According to the present invention, since the microphone is directly incorporated in the earphone main body, it is possible to pick up only the sound generated in the ear without picking up the surrounding noise when switching to the earphone microphone mode, and the other party can It becomes easy to hear. In this way, it is possible to realize stereophonic music playback using a mobile phone having a music playback function and a clear call that is hands-free but not affected by ambient noise. In addition, in the earphone microphone mode, the earphone speaker on which the microphone is operating is not operated, and the other earphone speaker is operated (the earphone speaker and the microphone incorporated in the same earphone main body are not operated simultaneously) Echoes do not occur, making it easier for the other party to hear and eliminates the need for complicated echo canceller structures and circuits. In this way, a clearer call can be realized while reducing costs.

２つのイヤホン本体の両方にマイクロホンを組み込む場合、リモコンに、イヤホンマイクモードに切り替えたときにどちらのイヤホン用スピーカを使用するかを選択するための選択スイッチを設けることにより、使用者の自由度が広がり、例えば携帯電話機のレシーバを当てる方の耳に装着されたイヤホン本体のイヤホン用スピーカを選択するなど使用者が使いやすいように設定できるようになる。こうして、イヤホンマイクとしての使い勝手の向上を図りながら、より明瞭な通話を実現できる。なお、例えば２つのイヤホン本体のケーブル長に差を付けるなど装着する耳が設定されている２つのイヤホン本体の一方にマイクロホンを組み込む場合、マイクロホンは左耳用のイヤホン本体（ケーブル長が短い方のイヤホン本体）に組み込むことにより、言語処理機能を有する左脳に相手側の音声をストレートに伝えることができるようになり、相手側の音声が聞き取りやすくなる。なぜならば、耳の聴覚神経は脳内で交差しており、左耳は右脳に、右耳は左脳につながっている。左耳から入った音声は右脳を経由して左脳の言語中枢に届き、右耳から入った音声はストレートに左脳の言語中枢に入る。右脳経由の情報処理は、左脳に直接インプットする場合よりも長く、１００分の１から２００分の１の時間差があり、外国語の習得や相手側の話しを正確に聞くには、右耳が利き耳である方が有利と言われているからである。こうして、スムーズな通話を実現できる。また、リモコンに設けられているフックスイッチを切替スイッチとして兼用し、フックスイッチをオン（オンフック）にすることでステレオイヤホンモードにし、フックスイッチをオフ（オフフック）にすることでイヤホンマイクモードにすることにより、専用の切替スイッチが不要となる。こうして、コストを抑え、使い勝手も向上しながら、より明瞭な通話を実現できる。さらに、マイクロホンを組み込むイヤホン本体にさらに第２のマイクロホンを組み込み、第２のマイクロホンはそれを組み込むイヤホン本体を耳に装着したときに耳外の音を拾うことにより、第２のマイクロホンを外部の騒音を拾ってノイズキャセル用として使用したり、外の音を拾い同じイヤホン本体に組み込んでいるイヤホン用スピーカとで補聴用として使用することができる。   When a microphone is incorporated into both of the two earphone bodies, a remote control is provided with a selection switch for selecting which earphone speaker to use when switching to the earphone microphone mode. For example, the user can select an earphone speaker of the main body of the earphone that is attached to the ear to which the receiver of the mobile phone is applied. In this way, a clearer call can be realized while improving usability as an earphone microphone. For example, when a microphone is incorporated in one of the two earphone bodies that have ears to be worn, such as by making a difference in the cable lengths of the two earphone bodies, the microphone is the earphone body for the left ear (the one with the shorter cable length). By incorporating it in the earphone main body), the other party's voice can be transmitted straight to the left brain having a language processing function, and the other party's voice can be easily heard. This is because the auditory nerves of the ear intersect in the brain, the left ear is connected to the right brain, and the right ear is connected to the left brain. Voice coming from the left ear reaches the language center of the left brain via the right brain, and voice coming from the right ear goes straight to the language center of the left brain. Information processing via the right brain is longer than when inputting directly to the left brain, and there is a time difference of 1/100 to 1/200. This is because it is said that the dominant ear is more advantageous. In this way, a smooth call can be realized. The hook switch provided on the remote control is also used as a changeover switch. When the hook switch is turned on (on hook), the stereo earphone mode is set. When the hook switch is turned off (off hook), the earphone microphone mode is set. This eliminates the need for a dedicated changeover switch. In this way, a clearer call can be realized while reducing costs and improving usability. Furthermore, the second microphone is further incorporated in the earphone main body incorporating the microphone, and the second microphone picks up the sound outside the ear when the earphone main body incorporating the microphone is attached to the ear, thereby making the second microphone an external noise. Can be used for noise cancellation, or can be used for hearing with a speaker for an earphone that is picked up outside sound and incorporated in the same earphone body.

以下、本発明の実施の形態を図面を参照して説明する。   Hereinafter, embodiments of the present invention will be described with reference to the drawings.

［実施の形態１］
図１は本発明の実施の形態１に係るリモコン付きステレオイヤホンマイクの全体図であり、図１において、１は音楽再生機能を有し所謂「音楽携帯」と呼ばれる携帯電話機、２は携帯電話機１に接続して使用するリモコン付きステレオイヤホンマイクである。リモコン付きステレオイヤホンマイク２は、一方の耳の穴（外耳道）に差し込んで使用するカナル型のイヤホン本体３および他方の耳の穴に差し込んで使用するカナル型のイヤホン本体４の２つと、フックスイッチ５およびボリューム６を設けたリモコン７と、携帯電話機１の側面に設けられている平型イヤホンジャック（図示省略）に抜き差し可能な平型イヤホンプラグ８とをケーブル９で接続して構成したもので、平型イヤホンプラグ８を平型イヤホンジャックに差し込むことで携帯電話機１と接続できるようになっている。 [Embodiment 1]
FIG. 1 is an overall view of a stereo earphone / microphone with a remote control according to Embodiment 1 of the present invention. In FIG. 1, reference numeral 1 denotes a mobile phone having a music playback function, so-called “music carrying”, and 2 denotes a mobile phone 1. This is a stereo earphone / microphone with a remote control that is used by connecting to. The stereo earphone microphone 2 with remote control includes a canal type earphone body 3 to be used by being inserted into one ear hole (ear canal) and a canal type earphone body 4 to be used by being inserted into the other ear hole, and a hook switch. 5 and a remote controller 7 provided with a volume 6 and a flat earphone plug 8 that can be inserted into and removed from a flat earphone jack (not shown) provided on the side of the mobile phone 1 is connected by a cable 9. The mobile phone 1 can be connected by inserting the flat earphone plug 8 into the flat earphone jack.

図２は一方のイヤホン本体３の断面図、図３は他方のイヤホン本体４の断面図であり、図２，図３に示すように、各イヤホン本体３，４は、上側に大径部１０を設け、耳の穴に差し込む下側の小径部１１の閉鎖端（底）に音孔１２を設けた段付きの有底円筒状のハウジング本体１３と、ハウジング本体１３の上部開口縁に下部開口縁を突き合わせて接合一体化しハウジング本体１３とで中空のハウジング１４を構成するとともに、ハウジング本体１３とは垂直な筒状のケーブル挿通部１５を設けたドーム状のカバー１６と、周縁部がハウジング本体１３の上部開口縁で支えられてハウジング本体１３の上部に嵌合され、放音面を下側の音孔１２に向けた状態でハウジング１４内に組み込まれるダイナミック型で円形のイヤホン用スピーカ１７と、ハウジング本体１３の小径部１１に外嵌し、イヤホン本体３，４の装着時にフィット感、耳内から外部への音漏れおよび外部から耳内への音の侵入を防止する遮音性を得るための弾性材料（例えばシリコンラバー）からなるイヤーピース（耳栓）１８とで構成されるカナル型のイヤホン構造を有している。   2 is a cross-sectional view of one earphone main body 3, and FIG. 3 is a cross-sectional view of the other earphone main body 4. As shown in FIGS. 2 and 3, each of the earphone main bodies 3 and 4 has a large-diameter portion 10 on the upper side. A bottomed cylindrical housing body 13 having a sound hole 12 at the closed end (bottom) of the lower small diameter portion 11 to be inserted into the ear hole, and a lower opening at the upper opening edge of the housing body 13 The housing body 13 and the housing main body 13 form a hollow housing 14 with the edges being joined and integrated, and a dome-shaped cover 16 provided with a cylindrical cable insertion portion 15 perpendicular to the housing main body 13, and the peripheral portion is the housing main body A dynamic circular earphone speaker 17 is supported by the upper opening edge of 13 and is fitted into the upper portion of the housing body 13 and is incorporated in the housing 14 with the sound emitting surface facing the lower sound hole 12. In order to obtain a sound-insulating property that is externally fitted to the small-diameter portion 11 of the housing body 13 and prevents fitting of the earphone bodies 3 and 4, sound leakage from the inside of the ear to the outside, and sound intrusion from the outside to the inside of the ear. It has a canal type earphone structure composed of an ear piece (ear plug) 18 made of an elastic material (for example, silicon rubber).

また、図３に示す一方のイヤホン本体４内には無指向性又は単一指向性のエレクトレットコンデンサ型のマイクロホン１９を１つ組み込むもので、そのマイクロホン１９を組み込む一方のイヤホン本体４は、ハウジング本体１３における大径部１０の周側壁の肉厚内に上面開放のマイク収納部２０を設けるとともに、音孔１２とイヤホン用スピーカ１７との間に形成されるハウジング本体１３と同心な主音道２１からイヤホン用スピーカ１７の直前で直角に分岐させて、マイク収納部２０を主音道２１に連通させる細い分岐音道２２を設けている。そして、マイクロホン１９は、マイク収納部２０に内向きで収納され、集音孔を分岐音道２１に対向させ、カバー１６で上から押さえられて、一方のイヤホン本体４内に組み込まれている。こうして、マイクロホン１９を直接一方のイヤホン本体４内に組み込むことで、使用者の口から出される音声や周囲の雑音など耳の外の音を拾うことなく使用者が声を出すときに耳内に発生する音声のみを拾うことができるように構成している。   Further, one earphone main body 4 shown in FIG. 3 incorporates one omnidirectional or unidirectional electret condenser type microphone 19, and one earphone main body 4 incorporating the microphone 19 is a housing main body. 13 is provided within the thickness of the peripheral side wall of the large-diameter portion 10 at 13, and from the main sound path 21 concentric with the housing body 13 formed between the sound hole 12 and the earphone speaker 17. A thin branching sound path 22 is provided which branches at right angles immediately before the earphone speaker 17 and communicates the microphone housing portion 20 with the main sound path 21. The microphone 19 is housed inward in the microphone housing portion 20, and the sound collection hole is opposed to the branch sound path 21 and is pressed from above by the cover 16, and is incorporated in one earphone body 4. In this way, by incorporating the microphone 19 directly into one of the earphone main bodies 4, when the user speaks without picking up sound outside the ear, such as voice from the user's mouth and ambient noise, It is configured so that only the generated sound can be picked up.

さらに、リモコン７に、同じイヤホン本体４に組み込んでいるイヤホン用スピーカ１７とマイクロホン１９とを択一的に携帯電話機１に切り替え接続する切替スイッチを設けるのであるが、その切替スイッチをフックスイッチ５で兼用するもので、フックスイッチ５のオン（オンフック）時にイヤホン用スピーカ１７を携帯電話機１に接続し、フックスイッチ５のオフ（オフフック）時にマイクロホン１９を携帯電話機１に接続している。こうして、リモコン付きステレオイヤホンマイク２を、リモコン７に設けられているフックスイッチ５のオン／オフ（オンフック／オフフック）に連動して、２つのイヤホン用スピーカ１７のみを動作させるステレオイヤホンモードと、１つのマイクロホン１９を動作させ、かつ、マイクロホン１９が動作している方のイヤホン用スピーカ１７は動作させず、他方のイヤホン用スピーカ１７を動作させる（同じイヤホン本体４に組み込んでいるイヤホン用スピーカ１７とマイクロホン１９は同時に動作させない）イヤホンマイクモードとに切り替えるように構成している。   Further, the remote controller 7 is provided with a selector switch for selectively switching and connecting the earphone speaker 17 and the microphone 19 incorporated in the same earphone body 4 to the mobile phone 1. The earphone speaker 17 is connected to the mobile phone 1 when the hook switch 5 is on (on hook), and the microphone 19 is connected to the mobile phone 1 when the hook switch 5 is off (off hook). In this way, the stereo earphone microphone 2 with the remote control is operated in conjunction with the on / off (on hook / off hook) of the hook switch 5 provided on the remote control 7 to operate only the two earphone speakers 17 and 1 One of the microphones 19 is operated, and the earphone speaker 17 on which the microphone 19 is operating is not operated, and the other earphone speaker 17 is operated (the earphone speaker 17 incorporated in the same earphone body 4 and The microphone 19 is not operated at the same time) and is configured to be switched to the earphone microphone mode.

なお、フックスイッチ５は、それをオフ（オフフック）にすることで、携帯電話機１で電話をかけようとして相手方の電話番号を発信するときや携帯電話機１に着信があった場合に電話を受けるときに、携帯電話機１に設けられている発信スイッチの代わりに、リモコン７に内蔵の制御回路を介して携帯電話機１に内蔵の制御回路に対して発信・応答信号を出力し、オン（オンフック）にすることで、電話を切るときに携帯電話機１に設けられている終話スイッチの代わりに、リモコン７に内蔵の制御回路を介して携帯電話機１に対して終話信号を出力し、携帯電話機１をリモートコントロールするもので、リモコン付きステレオイヤホンマイク２のステレオイヤホンモードとイヤホンマイクモードの切り替えもリモコン７に内蔵の制御回路を介して行われる。リモコン７にはそのような制御回路の他、２つのイヤホン用スピーカ１７の音量をボリューム６操作に基づいて調整する音量調整回路、マイクロホン１９の周波数特性補正回路が組み込まれている。マイクロホン１９は耳内で発生した音声のみを拾うが、耳内では高域が減退する傾向にあり、それをマイクロホン１９で拾いそのまま相手方に伝えると聞き取りにくい面があるため、ハイパスフィルターとアンプからなる周波数特性補正回路を使用し、高域を持ち上げて明瞭度を上げるようにしている。ハイパスフィルターとアンプの代わりに、プログラムによって自由に調整ができる専用のイコライジング用ＩＣかららなる周波数特性補正回路を使用してもよい。   The hook switch 5 is turned off (off-hook) so that when the mobile phone 1 makes a call to the other party in order to make a call or when the mobile phone 1 receives an incoming call, In addition, instead of the transmission switch provided in the cellular phone 1, a transmission / response signal is output to the control circuit incorporated in the cellular phone 1 via the control circuit incorporated in the remote control 7, and turned on (on hook). Thus, instead of the call end switch provided in the mobile phone 1 when the telephone is disconnected, a call end signal is output to the mobile phone 1 via the control circuit built in the remote controller 7. The remote control 7 has a built-in control circuit that switches between the stereo earphone mode and the earphone microphone mode of the stereo earphone microphone 2 with remote control. It is carried out through. In addition to such a control circuit, the remote controller 7 incorporates a volume adjustment circuit for adjusting the volume of the two earphone speakers 17 based on volume 6 operation, and a frequency characteristic correction circuit for the microphone 19. The microphone 19 picks up only the sound generated in the ear, but the high frequency tends to decrease in the ear, and if it is picked up by the microphone 19 and transmitted to the other party as it is, there is a surface that is difficult to hear. A frequency characteristic correction circuit is used to raise the high range and increase the clarity. Instead of the high-pass filter and the amplifier, a frequency characteristic correction circuit including a dedicated equalizing IC that can be freely adjusted by a program may be used.

上記のように構成したリモコン付きステレオイヤホンマイク２は、それを携帯電話機１に接続し、例えばマイクロホン１９を組み込んでいないイヤホン本体３を右耳の穴に差し込んで装着するとともに、マイクロホン１９を組み込んでいるイヤホン本体４を左耳の穴に差し込んで装着した使用状態で、携帯電話機１の音楽再生機能を起動させると、携帯電話機１からそれに保存された音楽データなどが各イヤホン本体３，４に組み込んでいる２つのイヤホン用スピーカ１７に入力されて、そこで再生される。これにより、使用者は両耳で音楽を聴くことができる（ステレオイヤホンモード）。   The stereo earphone microphone 2 with a remote control configured as described above is connected to the mobile phone 1 and, for example, the earphone main body 3 not incorporating the microphone 19 is inserted into the hole of the right ear, and the microphone 19 is incorporated. When the music playback function of the mobile phone 1 is activated while the earphone main body 4 is inserted into the left ear hole, the music data stored in the mobile phone 1 is incorporated into each earphone main body 3, 4. Are input to the two earphone speakers 17 and reproduced there. Thereby, the user can listen to music with both ears (stereo earphone mode).

また、音楽を聴いている際に着信があった場合、その着信中にフックスイッチ５をオフ（オフフック）にすることで、それを携帯電話機１に内蔵の制御部が確認し、割り込み処理として音楽再生を一時停止して電話機能を起動させるとともに、リモコン付きステレオイヤホンマイク２側ではステレオイヤホンモードからイヤホンマイクモードに切り替えられ、使用者の発声に伴って周囲の雑音などを拾うことなく左耳内に発生する音声のみがマイクロホン１９で拾われ、そこで電気信号に変換されて携帯電話機１に出力され、相手側の音声信号が携帯電話機１から右耳に装着したイヤホン本体３のイヤホン用スピーカ１７に入力されて、そこで再生される。これにより、使用者は右耳で相手側の音声を聞き取りながら、ハンズフリーで通話を行うことができる。   Also, when an incoming call is received while listening to music, the hook switch 5 is turned off (off-hook) during the incoming call, and the control unit built in the mobile phone 1 confirms this, and the music is processed as an interrupt process. In addition to suspending playback and activating the telephone function, the stereo earphone / microphone with remote control 2 can be switched from stereo earphone mode to earphone / microphone mode, so that the user can speak within the left ear without picking up ambient noise. Is picked up by the microphone 19 and converted into an electrical signal and output to the mobile phone 1, and the other party's audio signal is sent from the mobile phone 1 to the earphone speaker 17 of the earphone body 3 attached to the right ear. It is input and played there. As a result, the user can make a hands-free call while listening to the other party's voice with the right ear.

そして、フックスイッチ５をオン（オンフック）にして終話すると、音楽再生の一時停止が解除され、音楽再生が再開されるとともに、リモコン付きステレオイヤホンマイク２側ではイヤホンマイクモードからステレオイヤホンモードに戻される。これにより、使用者は再び両耳で音楽を聴くことができる。   When the hook switch 5 is turned on (on hook) and the call is finished, the music playback pause is released, the music playback is resumed, and the stereo earphone microphone 2 with remote control is returned from the earphone microphone mode to the stereo earphone mode. It is. Thereby, the user can listen to music with both ears again.

以上、実施の形態１のリモコン付きステレオイヤホンマイク２は、音楽再生機能を有する携帯電話機１に接続し使用するリモコン付きステレオイヤホンマイクであって、耳の穴に差し込む型の２つのイヤホン本体３，４の一方にマイクロホン１９を組み込み、リモコン７に、２つのイヤホン用スピーカ１７のみを動作させるステレオイヤホンモードと、１つのマイクロホン１９を動作させ、かつ、マイクロホン１９が動作している方のイヤホン用スピーカ１７は動作させず、他方のイヤホン用スピーカ１７を動作させるイヤホンマイクモードとに切り替える切替スイッチ５を設けたもので、マイクロホン１９を直接一方のイヤホン本体４内に組み込むから、イヤホンマイクモードに切り替えたときに周囲の雑音などを拾うことなく耳内に発生する音声のみを拾うことができるようになり、相手側が聞き取りやすくなる。こうして、音楽再生機能を有する携帯電話機１でのステレオによる臨場感のある音楽再生とハンズフリーでありながら周囲の雑音などに影響を受けない明瞭な通話を実現している。また、イヤホンマイクモードではマイクロホン１９が動作している方のイヤホン用スピーカ１７は動作させず、他方のイヤホン用スピーカ１７を動作させる（同じイヤホン本体４に組み込んでいるイヤホン用スピーカ１７とマイクロホン１９は同時に動作させない）から、エコーが発生せず、相手側がより聞き取りやすくなるとともに、複雑なエコーキャンセラー構造や回路が不要となる。こうして、コストを抑えながら、より明瞭な通話を実現している。さらに、リモコン７に設けられているフックスイッチ５を切替スイッチとして兼用し、フックスイッチ５をオン（オンフック）にすることでステレオイヤホンモードにし、フックスイッチ５をオフ（オフフック）にすることでイヤホンマイクモードにすることにより、専用の切替スイッチが不要となる。こうして、コストを抑え、使い勝手も向上しながら、より明瞭な通話を実現している。   As described above, the stereo earphone microphone 2 with a remote control according to the first embodiment is a stereo earphone microphone with a remote control that is used by being connected to the mobile phone 1 having a music playback function. The microphone 19 is incorporated in one of the four, the stereo earphone mode in which only the two earphone speakers 17 are operated in the remote controller 7, and the earphone speaker in which one microphone 19 is operated and the microphone 19 is operating. 17 is provided with a changeover switch 5 for switching to an earphone microphone mode for operating the other earphone speaker 17 without being operated. Since the microphone 19 is directly incorporated in one earphone main body 4, the earphone microphone mode is switched. Occasionally occurs in the ear without picking up ambient noise That will only be able to pick up the voice, the other party is likely to hear. In this way, a realistic music playback by stereo on the mobile phone 1 having a music playback function and a clear call that is hands-free but not affected by ambient noise and the like are realized. In the earphone microphone mode, the earphone speaker 17 on which the microphone 19 is operating is not operated, and the other earphone speaker 17 is operated (the earphone speaker 17 and the microphone 19 incorporated in the same earphone body 4 are Since no echo is generated, the other party can hear more easily, and a complicated echo canceller structure or circuit is not required. In this way, a clearer call can be realized while reducing costs. Further, the hook switch 5 provided on the remote controller 7 is also used as a changeover switch, and the earphone microphone is set by turning the hook switch 5 on (on hook) to switch to the stereo earphone mode and turning the hook switch 5 off (off hook).
