Description

本発明は、ヘッドホン(イヤホンを含む)、さらに詳しくは、複数の音源機器と同時に各別に接続して各音源機器から得られる異なる内容の音声情報や楽曲を任意に選択し組み合わせて同時に聴取することができるようにしたヘッドホンに関する。   The present invention relates to headphones (including earphones), more specifically, a plurality of sound source devices that are simultaneously connected to each other, and audio information and music of different contents obtained from each sound source device are arbitrarily selected and combined for listening simultaneously It relates to headphones that can be used.
イヤホンを含むヘッドホンは、外部音源機器から入力した電気信号を音声情報や楽曲などの音声信号に変換し耳介もしくは外耳道開口に押接して聴取する装置で、本体内の中空のハウジング部に外部音源機器が出力した電気信号を音声信号に変換し空気振動として伝搬するスピーカーユニットを有し、一端を本体内のスピーカーユニットの端子に接続し他端に外部音源機器と着脱自在に接続するためのプラグやジャックなどコネクタ類を持つ接続コードを備えている。   Headphones including earphones are devices that convert an electrical signal input from an external sound source device into a sound signal such as audio information or music, and press the ear pinna or the ear canal for listening to the external sound source. A plug that has a speaker unit that converts the electrical signal output from the device into an audio signal and propagates it as air vibration. One end is connected to the terminal of the speaker unit in the main unit and the other end is detachably connected to an external sound source device. It has a connection cord with connectors such as jacks and jacks.
ヘッドホンは、古くは、性能の低い無線通信機やラジオ受信機が提供する微弱な音声信号を外音の影響を遮断して聴取するために開発利用されたものであるが、外部開放空間への音声信号の伝搬(いわゆる音漏れ)や外音からの影響を抑制ないし遮断した気兼ねのない個人的聴取を可能にする特性が評価された結果、各種音源機器における電気信号から音声信号への変換と増幅伝搬の能力が格段に向上して外部スピーカーによる聴取に支障がなくなった後もその利用は大きな拡大を見せ、携帯容易な各種小型音源機器の普及と浸透−特に、iPod(登録商標)に代表されるデジタルオーディオプレイヤーや動画静止画像のデジタル再生機器などの飛躍的な音質向上と容量の増加、デジタルボイスレコーダーによる各種音声情報の日常的収録利用−の結果、屋内屋外を問わずヘッドホンによる音源機器の聴取利用はめざましく進み既に日常生活の中に定着していると言ってよい。   In the old days, headphones were developed and used to listen to weak sound signals provided by low-performance wireless communication devices and radio receivers while blocking the influence of external sound. As a result of the evaluation of the characteristics that enable personal listening without any hesitation to suppress or block the effects of sound signal propagation (so-called sound leakage) and external sound, conversion of electrical signals into sound signals in various sound source devices Even after the ability of amplification and propagation has improved dramatically, the use of external speakers has no longer hindered its use, and its use has expanded greatly, and the widespread use and penetration of various portable small-sized sound source devices—particularly represented by iPod (registered trademark) Dramatic sound quality improvement and capacity increase in digital audio players and digital still image playback equipment for movies, and daily recording of various types of audio information with digital voice recorders Use - the result, listening use of the sound source device in accordance with the headphones regardless of the indoor outdoor may be said that has been established in the remarkable proceed already everyday life.
このように、ヘッドホンは外音の影響や外部への音漏れを抑制する遮音性によって現在の幅広い利用をみるに至ったが、逆にこの特性に起因する一つの問題点も指摘されこれを解決するヘッドホンの開発提供も求められている。   In this way, headphones have seen widespread use today due to the sound insulation that suppresses the influence of external sound and sound leakage to the outside, but conversely, one problem caused by this characteristic was pointed out and solved There is also a need to develop and provide headphones.
すなわち、図5に示す如く、従来のヘッドホンでは外部音源機器との一対一対応が絶対的な前提とされ、耳介や外耳道開口に押接して利用するヘッドホン1の本体11内ハウジング部15には単一の外部音源機器と対応すべき一つまたは一組のスピーカーユニット13が設けられるに止まっており、ジャック2などのコネクタ類を備えた一本の接続コード14を介してスピーカーユニット13と対応する単一の外部音源機器を接続し、その音源機器が提供する音声情報や楽曲を聴取するよう構成されており、当然ながら一つのヘッドホンによって聴取できる音源機器は一つに限られ複数の音源機器が提供する異なる内容の音声情報や楽曲を一つのヘッドホンで同時に聴取することはできない。   That is, as shown in FIG. 5, in the conventional headphones, one-to-one correspondence with an external sound source device is an absolute premise, and the housing portion 15 in the main body 11 of the headphones 1 that is used while being pressed against the auricle or the ear canal opening is used. Only one or a set of speaker units 13 that should correspond to a single external sound source device is provided, and corresponds to the speaker unit 13 through a single connection cord 14 having connectors such as the jack 2. Connected to a single external sound source device, and is configured to listen to audio information and music provided by the sound source device. Of course, only one sound source device can be listened to with one headphone. You cannot listen to different types of audio information and music provided by the same headphones simultaneously.
しかし、小型軽量化によって多種多様な音源機器が日常的に携行利用され、デジタル化による容量の飛躍的増大で大量且つ多種類の音声情報や楽曲を保存集積して常時聴取できる現在、例えばボイスレコーダーに収録した講演内容やFMトランスミッターを介して受信し或いはオーディオプレーヤーに保存した外国語講座の音声情報を他のオーディオプレーヤーに保存集積した好みの楽曲と任意に組み合わせて同時に聴取したいなどの要望は決して少なくない。   However, a wide variety of sound source devices are carried on a daily basis due to the small size and light weight, and nowadays, for example, a voice recorder can store and collect a large amount of various kinds of audio information and music by a dramatic increase in capacity due to digitalization. There is never a need to listen to the lecture content recorded in, or to listen to the audio information of the foreign language course received through the FM transmitter or stored in the audio player in any combination with the favorite music stored and accumulated in other audio players. Not a few.
もちろん、外部音源機器とスピーカーユニットの一対一対応はヘッドホンに固有のものではなくスピーカー一般に共通するものであるが、開放空間へ音声信号を増幅して伝搬させるスピーカーであれば複数の異なる音源機器と各別に接続された複数組のスピーカーを稼働させることで各スピーカーの異なる音声情報や楽曲の全てを同時に聴取できるが、遮音性の高いヘッドホンをいくつ用意しても複数のヘッドホンを同時に装着して複数の音源機器の異なる音声情報や楽曲を同時に聴取することはできず、また接続コード端末のコネクタ類を分岐させても複数音源機器の切り替え利用が容易になるだけで要望されている同時聴取に応えることはできない。   Of course, the one-to-one correspondence between the external sound source device and the speaker unit is not unique to headphones but is common to speakers in general, but a speaker that amplifies and propagates an audio signal to an open space can be used with multiple different sound source devices. By operating multiple sets of separately connected speakers, you can listen to all the different audio information and music of each speaker simultaneously, but no matter how many headphones with high sound insulation, you can install multiple headphones at the same time. It is not possible to listen to different audio information and music from different sound source devices at the same time, and even if the connectors of the connection cord terminal are branched, it is easy to switch between multiple sound source devices and respond to the requested simultaneous listening It is not possible.
また、高機能のデジタル編集機器を用いれば複数の音源機器の異なる音声情報や楽曲を編集機器に同時に入力し単一のヘッドホンへ即時に出力することも可能であるが、これらデジタル編集機器の自在な操作は一般の音源機器利用者にとって容易でない上に、同時聴取の要望は小型軽量で携行性の高い普及型の外部音源機器による容易で簡便な操作を前提としているから、大型で携行性が悪く出力機器側の高度で複雑な操作に大きく依存するこの種デジタル編集機器によって同時聴取の要望に応えることはできない。   In addition, if a high-function digital editing device is used, it is possible to simultaneously input different audio information and music from multiple sound source devices to the editing device and output them immediately to a single headphone. Operation is not easy for general sound source equipment users, and the request for simultaneous listening is premised on easy and simple operation with a popular external sound source device that is compact and lightweight and highly portable. Unfortunately, this kind of digital editing equipment, which relies heavily on sophisticated and complex operations on the output equipment side, cannot meet the demand for simultaneous listening.
さらに、比較的簡易な編集ソフトを利用することでパソコンによって複数の音源機器の異なる音声情報や楽曲を組み合わせ或いは重ねて事前編集することも可能であるが、これは音源機器とヘッドホンの一対一対応利用に他ならず、事前編集の処理が面倒であるばかりでなく、聴取時の状況や気分に応じて複数音源機器の異なる音声情報や楽曲を任意に選択し組み合わせて同時に聴取したいとする要望とは全く相容れず、聴取時に各音源機器のいずれか一つの音声情報や楽曲の音量などを増減し或いは停止や再開を他の音源機器とは独立して随意に操作することもできない。   Furthermore, by using relatively simple editing software, it is possible to pre-edit by combining or overlapping different audio information and music of multiple sound source devices with a personal computer, but this is one-to-one correspondence between sound source devices and headphones. In addition to the use, the pre-editing process is not only cumbersome, but there is also a desire to listen at the same time by selecting and combining different audio information and music of multiple sound source devices according to the situation and mood at the time of listening At the time of listening, the sound information of any one of the sound source devices, the volume of the music, etc. can be increased / decreased or stopped or restarted independently of other sound source devices.
なお、かつては、ヘッドバンドなどの係止手段を備え耳介の全体を覆って押接利用する大径のものをヘッドホン、外耳道に挿入するイヤプラグを備え本体を外耳道開口部の係止位置に保持して押接する小径のものをイヤホンと称したりもしたが、現在ではヘッドバンドを備えずフックで耳介に係止して利用する小径の所謂ヘッドホンや、イヤプラグを備えず耳介の軟骨突起に係止することで本体を外耳道開口部に押接位置させる所謂イヤホンなどが多数提供されて両者の明確な境界が失われた結果、これら聴取装置の全てをヘッドホンと総称することが多くなっている。本明細書においてもこれに従った用語法を採っており、本明細書において用いる「ヘッドホン」の語は所謂ヘッドホンとイヤホンの全てを対象として含むものとする。   In the past, it was equipped with a locking means such as a headband and a large-diameter headphone that covered and used the entire auricle and was equipped with a headphone and an earplug that was inserted into the ear canal, and the main body was held at the locking position of the ear canal opening. The small-diameter type that presses down is sometimes called an earphone, but nowadays it is not equipped with a headband and is hooked to the auricle with a hook, so called a small-diameter headphone, or an auricular cartilage process without an earplug. Many so-called earphones that press the main body against the opening of the ear canal by being locked are provided and the clear boundary between them is lost. As a result, all of these listening devices are collectively referred to as headphones. . This terminology is also used in this specification, and the term “headphone” used in this specification includes all of so-called headphones and earphones.

図1は本発明に係るヘッドホンの一実施例を示すものであり、図3並びに図4はその実施の一態様を示すものであって、図示実施例には外耳道にイヤプラグ12を挿入して聴取利用する所謂イヤホン型のヘッドホンであって、右耳用と左耳用の一対の本体部分を持つステレオタイプないしハイファイタイプのヘッドホンである。   FIG. 1 shows an embodiment of a headphone according to the present invention, and FIGS. 3 and 4 show an embodiment of the embodiment. In the illustrated embodiment, an ear plug 12 is inserted into the ear canal to listen. It is a so-called earphone type headphone to be used, which is a stereo type or high fidelity type headphone having a pair of main body portions for right and left ears.
本実施例に係るヘッドホン1においては、本体11内部に形成された中空のハウジング部15に複数の異なる外部音源機器と各別に接続して入力された電気信号を聴取可能な音声信号に変換するためのダイナミック型の第1スピーカーユニット13aと第2スピーカーユニット13bの二つのスピーカーユニットが僅かにイヤプラグ方向へ傾く角度を付与された略平行位置に嵌設されており、それぞれのスピーカーユニット13a、13bの接続端子にはスピーカーユニット13a、13bのそれぞれが各別に対応すべき異なる外部音源機器と接続するための第1接続コード14aと第2接続コード14bの一端が接続固定され、ヘッドホン1の本体11の外部に展張するよう配設された各接続コード14a並びに14bの開放側の端部には各外部音源機器の接続部に挿入して接続する第1接続ジャック2aと第2接続ジャック2bが設けられている。(図1参照) In the headphone 1 according to the present embodiment, in order to convert an electrical signal input by connecting a plurality of different external sound source devices to a hollow housing portion 15 formed inside the main body 11 into an audible audio signal. The first speaker unit 13a and the second speaker unit 13b of the dynamic type are fitted in substantially parallel positions with an angle inclined slightly toward the earplug direction, and each of the speaker units 13a and 13b is fitted. One end of the first connection cord 14a and the second connection cord 14b for connecting each of the speaker units 13a and 13b to a different external sound source device to be individually supported is connected and fixed to the connection terminal. External sound source devices are provided at the open ends of the connection cords 14a and 14b arranged to extend outside. There are provided a first connection jack 2a and a second connection jack 2b which are inserted into and connected to each other. (See Figure 1)
図3および図4に示す通り、左右一対のヘッドホン1の本体11内に嵌設された第1スピーカーユニット13aおよび第2スピーカーユニット13bと複数の異なる外部音源機器(第1外部音源機器4aおよび第2外部音源機器4b)を各別に接続する第1接続コード14aと第2接続コード14bは、外部音源機器との接続用コネクタである第1接続ジャック2aと第2接続ジャック2bを設けた開放端部側においては各一本に分岐され、中間部方向の適宜位置で平行状態に被覆されているが、左右一対の本体11内に嵌設した二組の第1スピーカーユニット13aおよび第2スピーカーユニット13bそれぞれの端子部分と接続固定するため、ヘッドホン1本体11方向の適宜位置で各1本の第1接続コード14aと第2接続コード14bを各2本ずつに分岐させ、一組の第1接続コード14aと第2接続コード14bそれぞれの各他端部を左耳用の本体11内に嵌設された第1スピーカーユニット13aと第2スピーカーユニットの端子部分に接続し、他の一組の第1接続コード14aと第2接続コード14bそれぞれの各他端部を右耳用の本体11内の第1スピーカーユニット13aと第2スピーカーユニットの端子部分に接続している。   As shown in FIGS. 3 and 4, the first speaker unit 13a and the second speaker unit 13b fitted in the main body 11 of the pair of left and right headphones 1 and a plurality of different external sound source devices (the first external sound source device 4a and the first sound source device 4). 2 The first connection cord 14a and the second connection cord 14b for connecting the external sound source devices 4b) separately are open ends provided with a first connection jack 2a and a second connection jack 2b which are connectors for connection to the external sound source device. On the part side, each of the two parts is branched into one and covered in parallel at an appropriate position in the middle part direction, but two sets of the first speaker unit 13a and the second speaker unit fitted in the pair of left and right main bodies 11 are provided. In order to connect and fix each terminal portion 13b, two first connecting cords 14a and two second connecting cords 14b are provided at appropriate positions in the direction of the headphone 1 main body 11. The other end of each of the pair of first connection cord 14a and second connection cord 14b is connected to the terminal portions of the first speaker unit 13a and the second speaker unit that are fitted in the left ear main body 11. Connect the other end of each of the other pair of the first connection cord 14a and the second connection cord 14b to the terminal portions of the first speaker unit 13a and the second speaker unit in the main body 11 for the right ear. ing.
また、図3並びに図4に示す実施の態様においては、各外部音源機器4a並びに4bと二組の各スピーカーユニット13aおよび13bを接続する第1接続コード14aと第2接続コード14bの中間部適宜位置にボリュームコントローラー3を介設し、調整ダイヤルを持つ第1ボリューム3aと第2ボリューム3bのそれぞれを各接続コード14aと14bに各別に接続している。(なお、本実施例では、ボリュームコントローラー3の介設位置において、開放端側では各1本ずつであった第1接続コード14aと第2接続コード14bを各2本ずつに分岐させている。)   Further, in the embodiment shown in FIG. 3 and FIG. 4, an intermediate portion between the first connection cord 14a and the second connection cord 14b for connecting the external sound source devices 4a and 4b and the two sets of speaker units 13a and 13b as appropriate. A volume controller 3 is provided at a position, and the first volume 3a and the second volume 3b having an adjustment dial are connected to the connection cords 14a and 14b, respectively. (In the present embodiment, at the interposition position of the volume controller 3, the first connection cord 14a and the second connection cord 14b, which are one each on the open end side, are branched into two each. )
本実施例に係るヘッドホンは以上の構成を有し、図示された実施の態様のごとく用いられるものであるから、異なる二つの外部音源機器4aおよび4bから出力された異なる電気信号はそれぞれに対応するよう接続された異なるスピーカーユニット13aと13bで各別に音声信号に変換されるから、各スピーカーユニット13aと13bを嵌設した左右一対の本体11を有する一つのヘッドホン1を装着するだけで、任意に選択して組み合わせた2種類の異なる内容の音声情報や楽曲を同時に聴取して楽しむことができる。   Since the headphones according to the present embodiment have the above-described configuration and are used as in the illustrated embodiment, different electric signals output from the two different external sound source devices 4a and 4b correspond to each other. Since the different speaker units 13a and 13b connected in this way are converted into audio signals separately, it is possible to arbitrarily connect one headphone 1 having a pair of left and right main bodies 11 fitted with the speaker units 13a and 13b. It is possible to listen and enjoy two types of differently selected audio information and music that are selected and combined at the same time.
また、本実施例に係るヘッドホンでは外部音源機器4a、4bとスピーカーユニット13a、13bを結ぶ2種類の接続コード14a、14bの中間位置に各接続コードを介して出力されている電気信号を各別に独立して調整操作し各スピーカーユニット13a、13b側で得られる音声信号の音量を任意に増減するボリューム3a、3bを設けているから、例えば、ボイスレコーダーに収録した講演の音声情報の背後にデジタルオーディオプレイヤーの楽曲を流して同時聴取していて講演の重要な音声情報部分に集中したくなった場合、楽曲の音量だけを最低度まで下げ或いは講演部分の音量だけを上げることができるなど、状況と時宜に応じた随意の調整利用が可能になっているから同時聴取の要望を真に適えるものとなっている。   Further, in the headphones according to the present embodiment, the electric signals output via the connection cords are separately provided at intermediate positions between the two types of connection cords 14a and 14b connecting the external sound source devices 4a and 4b and the speaker units 13a and 13b. Volumes 3a and 3b that can be adjusted independently to increase or decrease the volume of the audio signal obtained on each speaker unit 13a and 13b are provided. For example, digitally behind the audio information of a lecture recorded in a voice recorder If you want to concentrate on the important audio information part of the lecture while listening to the music of the audio player and listening to it at the same time, you can lower the volume of the music to the lowest level or increase the volume of the lecture part. Because it is possible to use the system at any time, the request for simultaneous listening is truly suitable.
なお、本実施例では、ヘッドホン1の本体11内に形成されたハウジング部15に嵌設するスピーカーユニット13a、13bとして、振動板を取り付けたボイスコイルの中空部に永久磁石を配し永久磁石の磁界内にあるボイスコイルに電気信号を与えて振動させるダイナミック型のスピーカーユニットを用いたが、説明のための便宜に過ぎずあらゆるタイプのスピーカーユニットを用いて実施できることは言うまでもない。図2は他のタイプのスピーカーユニットを用いた一例を示すもので、圧電セラミックに金属板を貼着して振動薄膜としたクリスタル型のスピーカーユニット13a、13bを用いており、ダイナミック型のスピーカーユニットより薄く小形なものを利用できることから、楽曲再生に適した相対的に大形な第2スピーカーユニット13bの中心前方位置に音声情報再生に適した小形な第1スピーカーユニット13aを配置する同軸形態に嵌設している。   In this embodiment, as the speaker units 13a and 13b fitted in the housing portion 15 formed in the main body 11 of the headphone 1, a permanent magnet is arranged in the hollow portion of the voice coil to which the diaphragm is attached. Although a dynamic type speaker unit that applies an electric signal to a voice coil in a magnetic field to vibrate is used, it is needless to say that this is merely a matter of explanation and can be implemented using any type of speaker unit. FIG. 2 shows an example in which another type of speaker unit is used. Crystal type speaker units 13a and 13b which are made of a vibration thin film by attaching a metal plate to piezoelectric ceramic are used, and a dynamic type speaker unit is used. Since a thinner and smaller one can be used, the first speaker unit 13a, which is suitable for audio information reproduction, is arranged at the center front position of the relatively large second speaker unit 13b, which is suitable for music reproduction. It is fitted.
また、本実施例では外部音源機器4a、4bと各スピーカーユニット13a、13bを結ぶ接続コード14a、14bの中間位置にボリュームコントローラー3を介設するに止めているが、オンオフスイッチなど各接続コード14a、14b毎に独立して機能させるその他の調整操作手段を付設することも任意であり、本発明で開示した範囲に含まれる関係にある。   Further, in this embodiment, the volume controller 3 is stopped at an intermediate position between the connection cords 14a and 14b connecting the external sound source devices 4a and 4b and the speaker units 13a and 13b, but each connection cord 14a such as an on / off switch is used. It is also optional to provide other adjustment operation means that function independently for each 14b, and the relationship is within the scope disclosed in the present invention.
