実開平６－９２９３号公報Japanese Utility Model Publication No. 6-9293

　ＤＪ（Ｄｉｓｃ　Ｊｏｃｋｅｙ）用ヘッドホンは、通常とは異なる使われ方をする。例えば、ＤＪはヘッドホンを装着したまま、片方のチャンネル（ＬかＲのいずれか）のヘッドホンを耳からずらし、実際にホールに出ている音を直接聞く。もう一方の耳はヘッドホンを装着したまま再生音を聞く。そうして、ＤＪは実際に出ている音とヘッドホンの音を比較する。 DJ (Disc Jackey) headphones are used differently than usual. For example, a DJ, while wearing headphones, shifts the headphones of one of the channels (either L or R) from the ear and listens directly to the sound actually coming out of the hall. The other ear listens to the playback sound while wearing headphones. Then, the DJ compares the sound actually emitted with the sound of the headphones.

　この時、耳に装着された側のヘッドホンから聞こえる音が片方のチャンネルの音のみであると、それは実際にホールに出ている音とかなり異なる場合があり、音の比較がしにくい。また、耳からずらした側のヘッドホン（耳の近くにある）からも音が出ていると、ＤＪがその音を外から来る音と混同してしまうこともある。 At this time, if the sound that can be heard from the headphone attached to the ear is only the sound of one channel, it may be quite different from the sound that is actually in the hall, making it difficult to compare the sounds. In addition, if sound is emitted from the headphone on the side shifted from the ear (near the ear), the DJ may confuse the sound with the sound coming from the outside.

　本発明が解決しようとする課題としては、上記のものが例として挙げられる。本発明は、一方のヘッドホンで両チャンネルの音を聞き、他方のヘッドホンをミュート状態とすることが可能なヘッドホンを提供することを目的とする。 The above are examples of problems to be solved by the present invention. An object of the present invention is to provide a headphone that can listen to the sound of both channels with one headphone and can mute the other headphone.

　請求項１に記載の発明は、ヘッドホンであって、第１のチャンネル及び第２のチャンネルと、前記第１のチャンネルと前記第２のチャンネルとを制御する制御機能と、を備え、前記制御機能は、前記第１のチャンネルと前記第２のチャンネルにステレオ信号を与える第１のモードと、前記第１のチャンネルにモノラル信号を与え前記第２のチャンネルにミュート信号を与える第２のモードと、を有することを特徴とする。 The invention according to claim 1 is a headphone, comprising: a first channel and a second channel; and a control function for controlling the first channel and the second channel, wherein the control function Includes a first mode in which a stereo signal is applied to the first channel and the second channel, and a second mode in which a monaural signal is applied to the first channel and a mute signal is applied to the second channel; It is characterized by having.

　本発明の好適な実施形態では、ヘッドホンは、第１のチャンネル及び第２のチャンネルと、前記第１のチャンネルと前記第２のチャンネルとを制御する制御機能と、を備え、前記制御機能は、前記第１のチャンネルと前記第２のチャンネルにステレオ信号を与える第１のモードと、前記第１のチャンネルにモノラル信号を与え前記第２のチャンネルにミュート信号を与える第２のモードと、を有する。 In a preferred embodiment of the present invention, the headphone includes a first channel and a second channel, and a control function for controlling the first channel and the second channel, and the control function includes: A first mode in which a stereo signal is applied to the first channel and the second channel; and a second mode in which a monaural signal is applied to the first channel and a mute signal is applied to the second channel. .

　上記のヘッドホンは、２チャンネルの入力信号を受け取り、２チャンネルの出力信号を出力する。２チャンネルの出力信号は、制御機能により制御される。制御機能は、第１のチャンネルと第２のチャンネルにステレオ信号を与える第１のモードと、第１のチャンネルにモノラル信号を与え第２のチャンネルにミュート信号を与える第２のモードとで選択的に動作する。このヘッドホンによれば、入力された２チャンネルの信号をそのまま２チャンネルで出力する他、一方のチャンネルからモノラル信号を出力し他方のチャンネルをミュート状態とすることもできる。なお、本発明におけるヘッドホンはイヤホンを含む概念とする。 The above headphones receive 2-channel input signals and output 2-channel output signals. The 2-channel output signal is controlled by a control function. The control function is selective between a first mode in which a stereo signal is applied to the first channel and the second channel, and a second mode in which a monaural signal is applied to the first channel and a mute signal is applied to the second channel To work. According to this headphone, in addition to outputting the input two-channel signal as it is in two channels, a monaural signal can be output from one channel and the other channel can be muted. Note that the headphones in the present invention have a concept including earphones.

　上記のヘッドホンの一態様では、前記制御機能は、前記第２のチャンネルにモノラル信号を与え前記第１のチャンネルにミュート信号を与える第３のモードを有する。この態様では、モノラル信号及びミュート信号を出力するチャンネルを第１及び第２のチャンネルから選ぶことができる。 In one aspect of the above headphones, the control function has a third mode in which a monaural signal is given to the second channel and a mute signal is given to the first channel. In this aspect, the channel for outputting the monaural signal and the mute signal can be selected from the first and second channels.

　好適な例では、前記ミュート信号は無音である。 In a preferred example, the mute signal is silent.

　上記のヘッドホンの他の一態様では、前記制御機能は、前記ステレオ信号を合成して前記モノラル信号とする。この態様では、入力されたステレオ信号を合成してモノラル信号として出力するので、一方のチャンネルから入力ステレオ信号の成分を聞くことができる。 In another aspect of the above headphones, the control function synthesizes the stereo signal into the monaural signal. In this aspect, since the input stereo signal is synthesized and output as a monaural signal, the component of the input stereo signal can be heard from one channel.

　上記のヘッドホンの他の一態様は、前記第１のモードもしくは前記第２のモードを選択するための選択スイッチを有する。他の一態様では、前記選択スイッチにより前記第３のモードを選択可能である。これらの態様では、利用者が選択スイッチを操作することによりモードを切り替えることができる。 Another aspect of the above headphones has a selection switch for selecting the first mode or the second mode. In another aspect, the third mode can be selected by the selection switch. In these aspects, the mode can be switched by the user operating the selection switch.

　上記のヘッドホンの他の一態様は、前記選択スイッチが搭載された選択部を備え、前記第１のチャンネル及び前記第２のチャンネル用の１本のケーブルが前記選択部から導出されている。 Another aspect of the headphones includes a selection unit on which the selection switch is mounted, and one cable for the first channel and the second channel is led out from the selection unit.

　上記のヘッドホンの他の一態様は、前記選択スイッチが搭載された選択部を備え、前記第１のチャンネル用ケーブルと前記第２のチャンネル用ケーブルとが前記選択部から導出されている。 Another aspect of the headphones includes a selection unit on which the selection switch is mounted, and the first channel cable and the second channel cable are led out from the selection unit.

　上記のヘッドホンの他の一態様は、前記第１のチャンネルの音を出力する第１の放音部が設置された第１のイヤーカップと、前記第２のチャンネルの音を出力する第２の放音部が設置された第２のイヤーカップと、前記選択スイッチが搭載された選択部を備え、前記選択部は前記第１もしくは第２のイヤーカップに備えられている。 According to another aspect of the above headphones, a first ear cup provided with a first sound output unit that outputs the sound of the first channel, and a second ear that outputs the sound of the second channel are provided. A second ear cup provided with a sound emitting unit and a selection unit equipped with the selection switch are provided, and the selection unit is provided in the first or second ear cup.

　好適な例では、前記選択部から前記第１のチャンネル用ケーブルと前記第２のチャンネル用ケーブルとが取り外し可能である。 In a preferred example, the first channel cable and the second channel cable can be detached from the selection unit.

　以下、図面を参照して本発明の好適な実施例について説明する。 Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.

　［第１実施例］
　図１は、第１実施例に係るヘッドホンの構成を示す。図示のように、ヘッドホン１は、ヘッドホンユニット５と、制御ユニット１０とを備える。 [First embodiment]
FIG. 1 shows the configuration of a headphone according to the first embodiment. As illustrated, the headphone 1 includes a headphone unit 5 and a control unit 10.

　ヘッドホンユニット５は、使用者の頭に装着され、左右の耳に音を出力する。ヘッドホンユニット５は、左右の耳に装着される音声出力ユニットとしてのイヤーカップ６Ｌ、６Ｒと、イヤーカップ６Ｌに接続された入力ケーブル７と、を備える。入力ケーブル７は、左右２チャンネル分の音声信号をイヤーカップ６Ｌに供給する。入力ケーブル７によりイヤーカップ６Ｌに供給された音声信号のうち、Ｌ（左）チャンネル用の音声信号はイヤーカップ６Ｌ内の再生回路に供給され、Ｒ（右）チャンネル用の音声信号はヘッドホンユニット５内に設けられた配線を通じてイヤーカップ６Ｒ内の再生回路に供給される。イヤーカップ６Ｌ、６Ｒは本発明の放音部の一例である。 The headphone unit 5 is mounted on the user's head and outputs sound to the left and right ears. The headphone unit 5 includes ear cups 6L and 6R as sound output units attached to the left and right ears, and an input cable 7 connected to the ear cup 6L. The input cable 7 supplies audio signals for two left and right channels to the ear cup 6L.

It is supplied to the regeneration circuit in the ear cup 6R through the wiring provided inside. The ear cups 6L and 6R are examples of the sound emitting unit of the present invention.

　制御ユニット１０は、外部から入力信号を受け取り、信号を切り替えてヘッドホンユニット５へ出力する制御機能を有する。詳しくは、制御ユニット１０は、出力端子１１と、入力端子１２と、操作スイッチ１５とを備える。出力端子１１には、ヘッドホンユニット５の入力ケーブル７が接続される。入力端子１２には、図示しない音源からＬチャンネルとＲチャンネルを含むステレオ信号が入力される。 The control unit 10 has a control function of receiving an input signal from the outside, switching the signal, and outputting the signal to the headphone unit 5. Specifically, the control unit 10 includes an output terminal 11, an input terminal 12, and an operation switch 15. An input cable 7 of the headphone unit 5 is connected to the output terminal 11. A stereo signal including an L channel and an R channel is input to the input terminal 12 from a sound source (not shown).

　操作スイッチ１５は、利用者により操作され、ヘッドホンユニット５へ出力される音声信号を切り替えるためのものである。具体的に、操作スイッチ１５は、３接点スイッチとなっており、操作タブ１５ｘを操作することにより切り替えが行われる。 The operation switch 15 is operated by a user to switch an audio signal output to the headphone unit 5. Specifically, the operation switch 15 is a three-contact switch and is switched by operating the operation tab 15x.

　図２は、操作スイッチ１５による切り替え操作を説明する図である。図２（Ａ）は、操作タブ１５ｘが中央位置にある状態を示す。この場合、入力端子１２に入力されたステレオ信号がそのままヘッドホンユニット５へ出力される。即ち、Ｌチャンネルの入力信号がイヤーカップ６Ｌへ供給され、Ｒチャンネルの入力信号がイヤーカップ６Ｒへ供給される。 FIG. 2 is a diagram for explaining the switching operation by the operation switch 15. FIG. 2A shows a state where the operation tab 15x is in the center position. In this case, the stereo signal input to the input terminal 12 is output to the headphone unit 5 as it is. That is, the L channel input signal is supplied to the ear cup 6L, and the R channel input signal is supplied to the ear cup 6R.

　図２（Ｂ）は、操作タブ１５ｘがＲチャンネル位置にある状態を示す。この場合、入力端子１２に入力されたステレオ信号、即ちＬチャンネル信号とＲチャンネル信号を合成したモノラル信号がイヤーカップ６Ｒへ供給され、ミュート信号がイヤーカップ６Ｌへ供給される。 FIG. 2B shows a state where the operation tab 15x is at the R channel position. In this case, a stereo signal input to the input terminal 12, that is, a monaural signal obtained by synthesizing the L channel signal and the R channel signal is supplied to the ear cup 6R, and a mute signal is supplied to the ear cup 6L.
