【発明の属する技術分野】
本発明は、携帯型音響装置などの音響再生機本体に、スピーカ装置を接続して音楽などを聴くことができる小型音響再生装置に関するものである。
【０００２】
【従来の技術】
音楽などの音情報を記録したカセットテープやＭＤ（ミニディスク）などの録音媒体を装着自在に構成しながら、スピーカが設けられておらず、あるいは小型のスピーカを設けたものであるため、通常はイヤホンやヘッドホンを接続して、このイヤホンやヘッドホンから前記録音媒体の音楽などを再生して聞くことができる携帯型音響再生装置は知られている（例えば、特許文献１、２参照）。
【０００３】
この種の携帯型音響再生装置にスピーカを接続して、スピーカから音楽などを聴く手法としては、図１１に示すように、以下のような構成のスピーカ装置６０を携帯型音響再生装置９０に接続することが一般に行われている。
【０００４】
スピーカ装置６０は、左スピーカ６１が内蔵されている左スピーカユニット６２と、右スピーカ６３が内蔵されている右スピーカユニット６４と、家庭用ＡＣ電源８０などに接続されるＡＣアダプタ６５などを備えている。また、一方のスピーカユニット、例えば左スピーカユニット６２には、入力した音響信号を増幅する増幅回路（図示せず）と電池収納部とが内蔵されているとともに、音響信号入力用の接続コード６６と、右スピーカボックス部６４へのスピーカ接続用の接続コード６７とが接続され、さらに、ＡＣアダプタ６５の電源供給コード６５ｂの先端に設けられた電源供給端子６５ａが接続される電源入力端子部６８と、電源スイッチ６９とが設けられている。
【０００５】
なお、図１１における９２は携帯型音響再生装置９０に装着されるカセットテープやＭＤなどの情報記録媒体、８０はＡＣ電源である。
このスピーカ装置６０を使用する際には、左右のスピーカユニット６２、６４を適切な位置に配置した状態で、ＡＣアダプタ６５からの電源供給端子６５ａをスピーカ装置６０の電源入力端子部６８に接続し（または、スピーカユニット６２の電池収納部に電池を入れ）、スピーカ接続用の接続コード６７の先端に設けられたスピーカ接続用出力端子６７ａを右スピーカユニット６４のスピーカ接続用入力端子７０に接続し、さらに、音響信号入力用の接続コード６６の先端に設けられた音響信号入力用端子６６ａを、携帯型音響再生装置９０に設けられた音響信号出力用端子９１に差し込み、スピーカ装置６０の電源スイッチ６９をＯＮ状態にし、そして、携帯型音響再生装置９０を操作して再生状態とすることで使用できる。

【発明が解決しようとする課題】
しかしながら、このような従来構成の携帯型音響再生装置９０とスピーカ装置６０とを組み合わせて、スピーカ６１、６３から音楽などを聴こうとすると、左右のスピーカユニット６２、６４を配置した状態で、音響信号入力用の接続コード６６やスピーカ接続用の接続コード６７を接続しなければならず、さらに、ＡＣアダプタ６５を使用する際には、ＡＣアダプタ６５をＡＣ電源８０に接続した状態でＡＣアダプタ６５の電源供給コード６５ｂを左スピーカユニット６２に接続しなければならず（ＡＣ電源８０の代わりに電池を使用する際には、スピーカユニット６２の電池収納部に電池を入れなければならない）、多くの手間や時間がかかってしまうという課題があった。
【０００９】
また、左右のスピーカユニット６２、６４を配置する際などに、音響信号入力用の接続コード６６とスピーカ接続用の接続コード６７とが互いに絡んでしまう場合があり、さらに、ＡＣアダプタ６５を使用する際には電源供給コード６５ｂも絡んでしまうこともある。
【００１０】
また、携帯型音響再生装置９０とは別に、スピーカ装置６０への電源を供給する電源（ＡＣ電源や電池など）が必要である課題がある。
さらに、スピーカ装置６０の電源スイッチ６９をＯＮ状態にした後に、携帯型音響再生装置９０を操作しなければならず、２箇所のスイッチ操作を行わなければならないため、手間がかかるという問題もある。
【００１１】
本発明は上記課題や問題を解決するもので、多くの手間や時間をかけなくてもスピーカから発音できるように容易にセットでき、また、音響信号入力用の接続コードとスピーカ接続用の接続コードなどが互いに絡んだりすることがなく、さらには、スピーカ装置用の電源を単独に必要とすることがなく、操作性も良好な小型音響再生装置を提供することを目的とするものである。
【００１２】
【課題を解決するための手段】
上記課題や問題を解決するために本発明の小型音響再生装置は、小型の音響再生機本体と、この音響再生機本体を着脱自在に構成したスピーカ装置とを備え、前記音響再生機本体に、音響信号を出力する本体側音響信号出力端子を設け、前記スピーカ装置に、音を発生する左右のスピーカユニットと、これらの左右のスピーカユニットを連結する連結部と、音響再生機本体の装着時に音響再生機本体の本体側音響信号出力端子に直接接続可能な音響信号入力端子とを設け、音響再生機本体をスピーカ装置における連結部に対して装着可能に構成し、連結部に、音響再生機本体に設けた被係合部に装着時に係合して、音響再生機本体の装着位置を規制する係合部と、装着時に音響再生機本体の一部または内蔵されている物品に吸着するマグネット部とを設け、装着時にマグネット部により音響再生機本体が連結部に吸着されて、音響再生機本体の本体側音響信号出力端子がスピーカ装置の音響信号入力端子に直接接触するように構成したことを特徴とする。
【００１３】
この構成によれば、多くの手間や時間をかけなくてもスピーカから発音できるように容易にセットできる。
【００１４】
【発明の実施の形態】
本発明の請求項１記載の小型音響再生装置は、小型の音響再生機本体と、この音響再生機本体を着脱自在に構成したスピーカ装置とを備え、前記音響再生機本体に、音響信号を出力する本体側音響信号出力端子を設け、前記スピーカ装置に、音を発生する左右のスピーカユニットと、これらの左右のスピーカユニットを連結する連結部と、音響再生機本体の装着時に音響再生機本体の本体側音響信号出力端子に直接接続可能な音響信号入力端子とを設け、音響再生機本体をスピーカ装置における連結部に対して装着可能に構成し、連結部に、音響再生機本体に設けた被係合部に装着時に係合して、音響再生機本体の装着位置を規制する係合部と、装着時に音響再生機本体の一部または内蔵されている物品に吸着するマグネット部とを設け、装着時にマグネット部により音響再生機本体が連結部に吸着されて、音響再生機本体の本体側音響信号出力端子がスピーカ装置の音響信号入力端子に直接接触するように構成したことを特徴とする。
【００１５】
この構成によれば、連結部の係合部に音響再生機本体の被係合部を係合させた状態で連結部に音響再生機本体を装着するだけで、連結部のマグネット部により音響再生機本体が吸着されて保持され、極めて容易に音響再生機本体を装着できる。また、音響再生機本体をスピーカ装置に装着した時に、音響再生機本体の本体側音響信号出力端子にスピーカ装置の音響信号入力端子が直接接続し、従来のように音響信号入力用の接続コードを接続しなくても済むので、その分だけセットする際の手間や時間を省くことができる。さらに、音響信号入力用の接続コード自体がないので、当然ながら、音響信号入力用の接続コードが他のコードに絡むこともない。
【００１６】
請求項２記載の発明は、請求項１記載の小型音響再生装置において、左右のスピーカユニットは、連結部により相対的に移動可能に構成され、互いに離れてこれら左右のスピーカユニットの間に音響再生機本体を装着可能な装着用姿勢と、スピーカユニット同士が密着または近接する接合姿勢とにわたって、移動自在に支持されていることを特徴とする。
【００１７】
この構成によれば、装着用姿勢のスピーカ装置に音響再生機本体を装着することで、左右のスピーカから音楽などを良好に聞くことができ、また、持ち運ぶ際などには、スピーカ装置から音響再生機本体を分離させて、スピーカユニット同士が密着または近接する接合姿勢とすることでスピーカ装置をコンパクト化することができて持ち運び易くなる。
【００１８】
請求項３記載の発明は、請求項１または２に記載の小型音響再生装置において、音響再生機本体が充電可能に構成され、スピーカ装置に、音響再生機本体に収納した充電電池を充電する充電回路が配設されていることを特徴とする。
【００１９】
この構成によれば、スピーカ装置を、音響再生機本体に収納した充電電池を充電する充電装置としても兼用することができる。
請求項４記載の発明は、請求項１〜３の何れかに記載の小型音響再生装置において、音響再生機本体に、音響再生機本体の遠隔操作を行うための制御信号を入出力する制御端子を設け、スピーカ装置に、前記音響再生機本体の制御端子を外部に露出させる孔部を形成し、前記音響再生機本体の制御端子に、操作部および表示部を有するリモートコントロール部の接続端子を装着自在としたことを特徴とする。
【００２０】
この構成によれば、スピーカ装置に音響再生機本体を装着して、音響再生機本体の制御端子に、スピーカ装置の孔部を通してリモートコントロール部の接続端子を装着することで、リモートコントロール部の表示部を見ながら、リモートコントロール部の操作部などにより音響再生機本体を操作することができる。
【００２１】
請求項５記載の発明は、請求項１〜４の何れかに記載の小型音響再生装置において、音響再生機本体におけるスピーカ装置への装着時に外部に露出している箇所に、音響再生機本体を単独で使用する際だけでなく、音響再生機本体をスピーカ装置に装着した際にも操作することが可能な操作部を設け、スピーカ装置に操作部を設けていないことを特徴とする。
【００２２】
この構成によれば、スピーカ装置に音響再生機本体を装着した場合でも音響再生機本体の操作部を用いて自由に操作することができ、スピーカ装置に操作部を設けていないので、スピーカ装置に操作部を設けている構造のものに比べて安価に製造できる。
【００２３】
請求項６記載の発明は、請求項１〜５の何れかに記載の小型音響再生装置において、連結部に設けたマグネット部が、音響再生機本体に内蔵させた電池に吸着するように構成したことを特徴とする。
【００２４】
この構成によれば、音響再生機本体自体に、マグネット部により吸着させる部分を設けなくて済む。
請求項７記載の発明は、請求項１〜６の何れかに記載の小型音響再生装置において、装着時に音響再生機本体の被係合部に係合する連結部の係合部が、連結部の底面部から上方に突出する第１のガイドリブと、音響再生機本体の背面部に臨む連結部の本体部から手前に突出する第２のガイドリブとから構成され、連結部の本体部にマグネット部が前後に弾性的に支持されていることを特徴とする。
【００２５】
この構成によれば、第１のガイドリブと第２のガイドリブとにより、音響再生機本体を連結部に対して、前後、上下ならびに左右に、位置決めした状態で、マグネット部により良好に吸着することができる。
【００２６】
以下、本発明の実施の形態について、図面に基づき説明する。
図１〜図３、図１０に示すように、本発明の実施の形態に係る小型音響再生装置１は、小型の音響再生機本体２と、この音響再生機本体２を着脱自在に構成したスピーカ装置３と、操作部４ａおよび液晶の表示部４ｂを有し、これらの音響再生機本体２やスピーカ装置３を遠隔操作するリモートコントロール部４と、家庭用ＡＣ電源５などに接続され、これらの音響再生機本体２やスピーカ装置３に電力を供給可能なＡＣアダプタなどのＡＣアダプタ６（図１０参照）と、イヤホン接続コード（またはヘッドホン接続コード）７に接続されたイヤホン（またはヘッドホン：図示せず）などを備えている。
【００２７】
図５に示すように、音響再生機本体２は、スピーカ装置３から分離した単体の状態で、リモートコントロール部４とイヤホン（またはヘッドホン：イヤホン接続コード７の部分のみ図示する）などを接続して使用可能とされている。この音響再生機本体２は、録音媒体としてのＭＤ（ミニディスク）が上面部２ａより装着自在とされ、スピーカは設けられていない。音響再生機本体２の内部には充電電池１１が内蔵されているが、別途に側方に電池を収納した電池収納部１２を取り付け可能とされ、この電池収納部１２を取り付けることで、電池収納部１２内の電池によっても駆動可能とされている。
【００２８】
音響再生機本体２の左側面２ｂ（図５においては右面側に図示している）には、電池収納部１２に設けられた電源供給端子１２ａ、１２ｂに接続自在な電源入出力端子１３ａ、１３ｂが設けられており、電池収納部１２に回転自在に取り付けられている固定用雄ねじ部１４を、音響再生機本体２の左側面２ｂに設けられている固定用雌ねじ部１５に位置させた状態で、電池収納部１２の固定用つまみ１９を手で回すことで、固定用雄ねじ部１４を固定用雌ねじ部１５にねじ込んで固定できるようになっている。また、図６（ａ），（ｂ）に示すように、音響再生機本体２の左側面２ｂにおける上面部２ａ寄りの箇所には、充電電池１１を収納または取り出す際に開閉する電池用開閉蓋１１ａが設けられ、この電池用開閉蓋１１ａを開けた状態で、音響再生機本体２内における背面２ｄ側前面寄り箇所に、例えば、角型扁平形状の充電電池１１が挿入されて内蔵される。なお、図５における１２ｃは、音響再生機本体２の左側面２ｂに形成された凹部１６に嵌まり込む周り止め凸部であり、電池収納部１２の取り付けの際に、電池収納部１２が回動することを防止する。
【００２９】
音響再生機本体２の右側面２ｃ（図５においては左面側に図示している）には、音響再生機本体２の遠隔操作を行うための操作信号と表示内容信号とからなる制御信号と、音響再生機本体２で再生した音響信号とを入出力するジャック型の制御・音響信号入出力端子１７が設けられており、操作部４ａおよび表示部４ｂを有するリモートコントロール部４のプラグ型の接続端子４ｃやイヤホン、ヘッドホンなどを接続可能とされている。したがって、制御・音響信号入出力端子１７は、音響再生機本体２の遠隔操作を行うための操作信号を含む制御信号を入出力する制御信号端子（操作信号入力端子）としての機能や、音響信号を出力する本体側音響信号出力端子としての機能を１箇所にまとめて設けられている。なお、４８は音響再生機本体２の蓋部４９を開口させて録音媒体を着脱可能な姿勢にする開閉用レバーである。また、図１に示すように、音響再生機本体２の前面部２ｅ（蓋部４９の前面部）における上面部２ａ寄りの箇所には、音量増加押ボタン１８ａ、音量減少押ボタン１８ｂ、早送りボタン１８ｃ、戻しボタン１８ｄ、再生・停止ボタン１８ｅからなる操作部１８が設けられている。
【００３０】
音響再生機本体２には、音響再生機本体２側より入力した音響信号を増幅してスピーカ装置３の左右のスピーカユニット２３、２４に出力することができる増幅回路なども内蔵されている。また、音響再生機本体２の背面２ｄにおける下面部２ｆへの角部近傍箇所には、スピーカ装置３との接続端子９が集中して設けられている。この接続端子９は、左スピーカユニット２３の陽極側と陰極側とに接続される左スピーカ端子９ａ，９ｂと、右スピーカユニット２４の陽極側と陰極側とに接続される右スピーカ端子９ｃ，９ｄと、音響再生機本体２の充電電池１１を充電するための充電用陰極側端子９ｅと、音響再生機本体２側からスピーカ装置３側へ電力を供給する電源用陰極側端子９ｆと、充電用陽極側端子と電源陽極側端子とを兼ねる共通陽極側端子９ｇとから構成されて、これらの端子９ａ〜９ｇが横方向に並べられて配設されている。
【００３１】
また、音響再生機本体２の下面部２ｆにおける略中央箇所と、音響再生機本体２の背面部２ｄにおける略中央箇所とには、後述する連結部３０の第１のガイドリブ３４に係合する第１被係合凹部８ａと、連結部３０の第２のガイドリブ３５に係合する第２被係合凹部８ｂとが形成されている。
【００３２】
リモートコントロール部４の先端部には、イヤホンの入力端子７ａに接続可能な音響信号出力端子４ｄが設けられている。なお、イヤホンは、リモートコントロール部４に接続することができるが、イヤホンの入力端子７ａを音響再生機本体２の制御・音響信号入出力端子１７に直接差し込んで聞くことも可能とされている。
【００３３】
音響再生機本体２を単体で使用する際には、充電電池１１を収納したり、電池収納部１２を取り付けたりして、電源が供給された状態とし、イヤホンを取り付け、またはリモートコントロール部４を介してイヤホンを取り付けた状態で、音響再生機本体２の操作部１８やリモートコントロール部４の操作部４ａを操作することにより、音響再生機本体２で再生した音楽などをイヤホンから聴くことができる。
【００３４】
図１、図２に示すように、スピーカ装置３は、音を発生するスピーカ２１、２２がそれぞれ設けられているボックス形状の左右のスピーカユニット２３、２４と、これらの左右のスピーカユニット２３、２４を左右にスライド可能な状態で連結する連結部３０とを備えており、音響再生機本体２に収納した充電電池１１を充電する充電回路なども内蔵され、充電回路は、音響再生機本体２への電源回路も兼ねている。
【００３５】
図２に示すように、左右のスピーカユニット２３、２４にはそれぞれ左右方向中央側に伸びる上下２つのスライドロッド２５、２６が一体形成され、また、これに対応して、連結部３０の本体部（音響再生機本体２の背面部２ｄに臨む部分）３０ａには、中央から左方向に延びる上下２つのガイド溝３１と、中央から右方向に延びる上下２つのガイド溝３２とが設けられている。そして、連結部３０の各ガイド溝３１、３２に、スピーカユニット２３、２４のスライドロッド２５、２６が嵌入され、この姿勢で、連結部３０に対して、左右のスピーカユニット２３、２４が、互いに離れてこれらの間に音響再生機本体２を装着できる装着用姿勢（図２参照）と、スピーカユニット２３、２４の内側側面同士が密着する接合姿勢（図８参照）とにわたって、スライド自在に支持されている。
【００３６】
図２、図８に示すように、連結部３０には、音響再生機本体２を背面側から受ける本体部３０ａだけでなく、音響再生機本体２を下方からも受ける底面部３０ｂが一体形成されている。そして、連結部３０における底面部３０ｂの後部と本体部３０ａの下端部とにかけて、音響再生機本体２を装着した際にこの音響再生機本体２の接続端子９に接触する接続端子部３３が設けられている。接続端子部３３には、音響再生機本体２の接続端子９と同様に、左スピーカ端子３３ａ，３３ｂと、右スピーカ端子３３ｃ，３３ｄと、充電用陰極側端子３３ｅと、電源用陰極側端子３３ｆと、充電用陽極側端子と電源用陽極側端子とを兼ねる共通陽極側端子３３ｇとが、横方向に並べられて配設されており、左スピーカ端子３３ａ，３３ｂは左スピーカ２１に接続され、右スピーカ端子３３ｃ，３３ｄは右スピーカ２２に接続される。また、音響再生機本体２を装着した際に、各端子９ａ〜９ｇ、３３ａ〜３３ｇ同士が良好に接触するように、連結部３０の接続端子部３３に設けられた各端子３３ａ〜３３ｇは、前側に付勢された状態で斜め下方に後退可能に取り付けられ、音響再生機本体２を装着した際には、連結部３０の接続端子部３３の各端子３３ａ〜３３ｇが、音響再生機本体２の接続端子９の各端子９ａ〜９ｇに押し付けられて確実に接続される。なお、連結部３０の接続端子部３３における外周壁部分は、音響再生機本体２を装着した際に、その外周壁部分で、音響再生機本体２の下部を受ける機能も有する。
【００３７】
連結部３０の底面部３０ｂには、その上面側から上方に突出する第１の係合部としての第１のガイドリブ３４が形成され、また、連結部３０の本体部３０ａの中央には前面側から手前に突出する第２の係合部としての第２のガイドリブ３５が形成されている。そして、スピーカ装置３に音響再生機本体２を装着した際に、第１のガイドリブ３４が音響再生機本体２の第１被係合凹部８ａに係合し、第２のガイドリブ３５が音響再生機本体２の第２被係合凹部８ｂに係合して、音響再生機本体２の装着位置を規制するようになっている。なお、また、図２における３８は音響再生機本体２の装着時に音響再生機本体２の前後方向位置を規制する位置規制リブである。
【００３８】
連結部３０の本体部３０ａの上部には、音響再生機本体２の装着時に、音響再生機本体２に内蔵されている充電電池１１に吸着する１対のマグネット部３６が設けられている。これらのマグネット部３６は、図７に示すように、連結部３０の本体部３０ａ内において左右に伸びるように配設され、前後に弾性変形可能に支持された支持アーム３７の両端部に固着されており、支持アーム３７の両端部およびマグネット部３６は樹脂製カバー（図示せず）にて覆われている。そして、これらのマグネット部３６により、音響再生機本体２に内蔵されている充電電池１１を吸着した状態では、音響再生機本体２が連結部３０の本体部３０ａ側に引き付けられた状態で配置されるようになっている。
【００３９】
図３、図１０に示すように、連結部３０の左側面部下部には、ＡＣアダプタ６の電源供給コード６ｂの先端に設けられた電源供給端子６ａが接続される電源入力端子部３９が設けられている。そして、家庭用ＡＣ電源５に接続したＡＣアダプタ６の電源供給コード６ｂを接続することでＡＣアダプタ６により変換されたＤＣ電源がスピーカ装置３を介して音響再生機本体２に供給されるようになっている。
【００４０】
図４（ａ）〜（ｃ）に示すように、連結部３０の右側面部には、音響再生機本体２の制御・音響信号入出力端子１７に接続される、リモートコントロール部４の接続端子４ｃ部分や、イヤホンの入力端子７ａ部分を通すための、開閉窓４０が開閉自在に設けられている。また、スピーカ装置３を装着姿勢にした時に、右スピーカユニット２４における前記開閉窓４０に臨む位置に、リモートコントロール部４の接続端子４ｃ部分や、イヤホンの入力端子７ａ部分やそのコードを通すためのコード用凹部２４ａが形成されている。そして、音響再生機本体２の装着時には、開閉窓４０を開けることで、音響再生機本体２の制御・音響信号入出力端子１７を直接外部に露出させることができ、この制御・音響信号入出力端子１７にリモートコントロール部４の接続端子４ｃやイヤホン接続コード７の入力端子７ａを直接接続することが可能に構成されている。
【００４１】
また、図３、図４（ａ）〜（ｃ）に示すように、連結部３０の背面には、この小型音響再生装置１を立設させることができるように折畳式のスタンド４６が上端で枢支されている。そして、スタンド４６を立てて、小型音響再生装置１を傾斜姿勢で立設させた際に、小型音響再生装置１が安定して立設できるように、連結部３０の底面部３０ｂには、ゴム脚を設けた傾斜脚部３０ｃ（図８参照）が形成されている。
【００４２】
この構成において、スピーカ装置３を使用する場合は、まず、図２に示すように、左右のスピーカユニット２３、２４が分離された装着用姿勢となるように連結部３０に対して左右のスピーカユニット２３、２４を左右にスライドさせる。そして、図９において矢印ａ，ｂにより音響再生機本体２の嵌合動作を示すように、まず、連結部３０の第１のガイドリブ３４（図２参照）が音響再生機本体２の第１被係合凹部８ａ（図６参照）に係合するように嵌合させ、次に、連結部３０の第２のガイドリブ３５（図２参照）が音響再生機本体２の第２被係合凹部８ｂ（図６参照）に係合するように嵌合させる。この際、図７に示すように、支持アーム３７の両端部に取り付けたマグネット部３６が音響再生機本体２に内蔵されている充電電池１１に吸着し、この結果、連結部３０の第１のガイドリブ３４と第２のガイドリブ３５とが音響再生機本体２の第１被係合凹部８ａと第２被係合凹部８ｂとに係合して位置決めされ、音響再生機本体２の接続端子９の各端子９ａ〜９ｇと連結部３０の接続端子部３３の各端子３３ａ〜３３ｇとが接触した状態で、音響再生機本体２がスピーカ装置３に固定される。
【００４３】
これにより、互いに接触した電源用陰極側端子９ｆ、３３ｆおよび共通陽極側端子９ｇ、３３ｇを介して、音響再生機本体２内の充電電池１１の電力がスピーカ装置３に供給され、また、ＡＣアダプタ６の電源供給端子６ａをスピーカ装置３に接続させると、ＡＣアダプタ６からの電力が、スピーカ装置３および充電用陰極端子９ｅ、３３ｅ、共通陽極側端子９ｇ、３３ｇを介して音響再生機本体２に供給される。また、左右のスピーカ端子９ａ〜９ｄ、３３ａ〜３３ｄ同士が接触される。したがって、この状態で、音響再生機本体２の操作部１８を操作して再生を指示することで、音響再生機本体２で再生された音楽などが、左右のスピーカユニット２３、２４から発せられる。
【００４４】
また、この場合に、図１に示すように、リモートコントロール部４を取り付けることにより、リモートコントロール部４の表示部４ｂを見ながら、何番目の曲か（トラック数）の確認や、モードの確認、曲中の演奏時間を視認することも可能であり、さらに、リモートコントロール部４にイヤホンを接続して、スピーカ装置３のスピーカ２１、２２とイヤホンとの両方から音楽などを聴くことも可能である。
【００４５】
上記構成によれば、連結部３０の第１のガイドリブ３４と第２のガイドリブ３５とが音響再生機本体２の第１被係合凹部８ａと第２被係合凹部８ｂとに係合するようにして連結部３０に音響再生機本体２を装着するだけの簡単な操作で、連結部３０のマグネット部３６により音響再生機本体２が吸着されて保持され、極めて容易に音響再生機本体２を装着できる。したがって、音響再生機本体２をスピーカ装置３に装着する際の手間や時間を大幅に省くことができて能率的に組付けることができる。
【００４６】
また、このような簡単な装着動作だけで、音響再生機本体２の接続端子９の各端子９ａ〜９ｇと連結部３０の接続端子部３３の各端子３３ａ〜３３ｇとが良好に接触した状態で直接接続され、従来のように音響信号入力用の接続コードや電源供給コードを接続しなくても済むので、その分だけセットする際の手間や時間を省くことができる。また、音響信号入力用の接続コードや電源供給コードがないので、当然ながら、音響信号入力用の接続コードや電源供給コードが他のコードに絡むこともない。さらに、従来のように音響再生機とスピーカ装置との電源をそれぞれ別個に設けなくても済むため、別個に設けた場合と比較して、製造コストを低減できる。
【００４７】
さらに、スピーカ装置３に充電回路が設けられて、スピーカ装置３が、音響再生機本体２に収納した充電電池１１を充電する充電装置としても兼用されるので、スピーカ装置と充電装置とを別個に設けた場合に比べて、配設スペースや収納スペースも最小限で済む。
【００４８】
また、図１などに示すように、スピーカ装置３に音響再生機本体２を装着することで、左右のスピーカユニット２３、２４から音楽などを良好に聞くことができながら、持ち運ぶ際などには、スピーカ装置３から音響再生機本体２を分離させて、図８に示すように、スピーカユニット２３、２４同士が密着する接合姿勢とすることでスピーカ装置３をコンパクト化することができて持ち運び易くなる。また、この小型音響再生装置１を収納する際でも、コンパクトな状態で小さなスペースに収納することができ、この場合においても、音響信号入力用やスピーカ接続用の接続コードがないので、当然ながら、収納時にこれらの接続コードが他のコードに絡むことがない。
【００４９】
また、図４（ａ）〜（ｃ）に示すように、スピーカ装置３に音響再生機本体２を装着した場合でも、連結部３０の開閉窓４０を開けて、リモートコントロール部４の接続コードやイヤホン接続コード７を、コード用凹部２４ａを通して、音響再生機本体２の制御・音響信号入出力端子１７に接続することが可能であり、リモートコントロール部４の表示部４ｂを見て、何番目の曲か（トラック数）の確認や、モードの確認、曲中の演奏時間を視認しながら、リモートコントロール部４の操作部４ａなどにより音響再生機本体２を操作することができるので、便利である。また、スピーカ装置３に表示部を設けずに、リモートコントロール部４の表示部４ｂを利用しているため、スピーカ装置などに表示部を設けた場合に比べて製造コストを低減させることができる。また、リモートコントロール部４の接続コードやイヤホン接続コード７を接続するための端子をスピーカ装置３に設けなくても済むので、その分だけ製造コストを低減することができる。

【００５１】
また、連結部３０に設けたマグネット部３６が、音響再生機本体２に内蔵させた充電電池１１に吸着するように構成したことにより、音響再生機本体２をスピーカ装置３に良好かつ容易に固定できる。しかも、マグネット部３６と充電電池１１とで磁路が形成されるので、音響再生機本体２自体に防磁機能を設けたり、音響再生機本体２自体に、マグネット部により吸着させる部分を別途に設けたりしなくて済む。
【００５２】
さらに、図７に示すように、マグネット部３６を、前後に弾性変形可能に支持された支持アーム３７の両端部に固着し、音響再生機本体２を吸着した状態では、音響再生機本体２が連結部３０の本体部３０ａ側に引き付けられた状態で配置されるようになっているとともに、マグネット部３６により音響再生機本体２を固定する際には、連結部３０の第１のガイドリブ３４と第２のガイドリブ３５とが音響再生機本体２の第１被係合凹部８ａと第２被係合凹部８ｂとに係合して位置決めされるので、音響再生機本体２の接続端子９の各端子９ａ〜９ｇと連結部３０の接続端子部３３の各端子３３ａ〜３３ｇとが良好に接触して、信頼性が向上する。
【００５３】
なお、上記実施の形態においては、音響再生機本体２にスピーカが全くない場合を述べたが、音響再生機本体に小型のスピーカがついており、さらにスピーカ装置３を接続することで、良質の音響を得ようとする場合にも適用可能である。また、上記実施の形態においては、左右のスピーカユニット２３、２４が接合姿勢では密着する場合を述べ、このように構成することで、接合姿勢でコンパクトに持ち運んだり収納したりすることができるが、これに限るものではなく、接合姿勢で左右のスピーカユニットが近接するように配置してもよい。
【００５４】
【発明の効果】
以上のように本発明によれば、音響再生機本体を、スピーカ装置における左右のスピーカユニットを連結する連結部に対して装着可能に構成し、連結部に、音響再生機本体に設けた被係合部に装着時に係合して、音響再生機本体の装着位置を規制する係合部と、装着時に音響再生機本体の一部または内蔵されている物品に吸着するマグネット部とを設け、装着時にマグネット部により音響再生機本体が連結部に吸着されて、音響再生機本体の本体側音響信号出力端子がスピーカ装置の音響信号入力端子に直接接触するように構成したことにより、連結部の係合部に音響再生機本体の被係合部を係合させた状態で連結部に音響再生機本体を装着するだけで、連結部のマグネット部により音響再生機本体が所定位置に吸着されて保持され、極めて容易に音響再生機本体を装着できて使い勝手が向上する。また、従来のように音響信号入力用の接続コードなどを接続しなくても済むので、その分だけセットする際の手間や時間を省くことができるとともに、当然ながら、音響信号入力用の接続コードが他のコードに絡むこともない。

また、左右のスピーカユニットを、連結部により相対的に移動可能に構成し、互いに離れてこれら左右のスピーカユニットの間に音響再生機本体を装着可能な装着用姿勢と、スピーカユニット同士が密着または近接する接合姿勢とにわたって、移動自在に支持させることで、スピーカ装置を使用する際には、装着用姿勢のスピーカ装置に音響再生機本体を装着して、左右のスピーカから音楽などを良好に聞くことができ、また、持ち運ぶ際などには、スピーカ装置から音響再生機本体を分離させて、スピーカユニット同士が密着または近接する接合姿勢とすることでスピーカ装置をコンパクト化することができて持ち運び易くなる。
【００５６】
また、スピーカ装置に、音響再生機本体に収納した充電電池を充電する充電回路を配設することで、スピーカ装置を、音響再生機本体に収納した充電電池を充電する充電装置としても兼用することができ、スピーカ装置と充電装置とを別個に設けた場合に比べて、配設スペースや収納スペースも最小限で済む。
【００５７】
さらに、スピーカ装置に、前記音響再生機本体の遠隔操作を行うための制御端子を外部に露出させる孔部を形成し、音響再生機本体の制御端子に、操作部および表示部を有するリモートコントロール部の接続端子を装着自在としたことにより、スピーカ装置に音響再生機本体を装着した場合でも、リモートコントロール部の表示部を見ながら、リモートコントロール部の操作部などにより音響再生機本体を操作することができ、しかも、リモートコントロール部の接続コードやイヤホン接続コードを接続するための端子をスピーカ装置に設けなくても済むので、その分だけ製造コストを低減することができる。
【００５８】
また、音響再生機本体におけるスピーカ装置への装着時に外部に露出している箇所に、音響再生機本体を単独で使用する際だけでなく、音響再生機本体をスピーカ装置に装着した際にも操作することが可能な操作部を設けることで、スピーカ装置に音響再生機本体を装着した場合でも音響再生機本体の操作部を用いて自由に操作することができながら、スピーカ装置に操作部を設けなくても済むので、スピーカ装置に操作部を設けている構造のものに比べて製造コストを安価にできる。
【００５９】
また、連結部に設けたマグネット部を、音響再生機本体に内蔵させた電池に吸着するように構成したことで、音響再生機本体をスピーカ装置に良好かつ容易に固定でき、しかも、マグネット部と電池とで磁路が形成されるので、音響再生機本体自体に防磁機能を設けたり、音響再生機本体自体に、マグネット部により吸着させる部分を別途に設けたりしなくて済む。
【００６０】
さらに、装着時に音響再生機本体の被係合部に係合する連結部の係合部を、連結部の底面部から上方に突出する第１のガイドリブと、音響再生機本体の背面部に臨む連結部の本体部から手前に突出する第２のガイドリブとから構成し、連結部の本体部にマグネット部を前後に弾性的に支持させることで、第１のガイドリブと第２のガイドリブとにより、音響再生機本体を連結部に対して、前後、上下ならびに左右に、位置決めした状態で、マグネット部により良好に吸着することができ、音響再生機本体の接続端子と連結部の接続端子とが良好に接触して、信頼性が向上する。
