Description

【０００１】
【発明の属する技術分野】
本発明は、音声入力が可能なマイクロフォンを取り付けることのできる音楽演奏装置に関する。
【０００２】
【従来の技術】
従来から、例えば、鍵盤を備えた音楽演奏装置を演奏する場合に、音楽演奏装置を演奏しながらマイクロフォンを用いて歌を歌うことが行われている。このような場合には、音楽演奏装置の近傍にマイクロフォンを保持するための保持装置を設置し、この保持装置にマイクロフォンを取り付けることにより、音楽演奏装置とマイクロフォンを同時に使用していた。
【０００３】
【発明が解決しようとする課題】
しかしながら、前述した従来の音楽演奏装置では、音楽演奏装置の他に別途マイクロフォンを保持するための保持装置を用意しなければならないため部品点数が多くなるという問題がある。また。音楽演奏装置の使用時における保持装置の設置や不使用時における保管や搬送等が煩雑になるという問題も有している。
【０００４】
【発明の概要】
本発明は、上記問題に対処するためになされたもので、その目的は、マイクロフォンの設置が簡単になるとともに部品点数が少なくコンパクトになる音楽演奏装置を提供することである。
【０００５】
上記の目的を達成するため、本発明にかかる音楽演奏装置の構成上の特徴は、音楽演奏装置本体に設けられねじ穴を備えた取付部と、取付部に取り付られ先端にねじが形成されたねじ棒を通すための穴を備えた被取付片とマイクロフォンを保持するためのマイク保持片とからなるホルダー部と、先端にねじが形成されたねじ棒を備え、ねじ棒を被取付片の穴に挿通させ被取付片の向きを調節した状態でねじを取付部のねじ穴に螺合させることにより、取付部に取り付けられる被取付片を、マイク保持片の向きを所定の方向に変更可能にして固定する固定部材とを備えたことにある。
【０００６】
前記のように構成した本発明の音楽演奏装置においては、音楽演奏装置本体に取付部が設けられているとともに、この取付部に係合可能な固定部材を備えている。そして、固定部材を取付部に係合させることにより、取付部に取り付けられる被取付片とマイクロフォンを保持するためのマイク保持片とを備えたホルダー部の被取付片を、マイク保持片の向きを所定の方向にして固定できるようにしている。
【０００７】
このため、音楽演奏装置を演奏する際には、音楽演奏装置本体に取付部および固定部材を介して取り付けられたホルダー部にマイクロフォンを取り付けて、音楽演奏装置本体を演奏しながらマイクロフォンに向かって歌を歌うことができる。また、その際、ホルダー部の向きを所定の方向に変更できるようになっているため、ホルダー部の向きを変更することによりマイクロフォンの向きをホルダー部とともに変更することができる。これによって、マイクロフォンを使用しやすい任意の方向に向けることができる。
【０００８】
また、本発明にかかる音楽演奏装置の他の構成上の特徴は、ホルダー部の被取付片とマイク保持片とを、取付部に対する位置を一定にして取り付けられる連結軸部とねじ棒を通すための穴が設けられた一対の支持片を備えた連結支持部とからなる連結部材と、ねじ棒を通すための穴が設けられこの穴が設けられた部分を一対の支持片間に配置させて取り付けられるホルダー部材とからなる別部材で形成し、固定部材を取付部に螺合させる際に、ホルダー部材を連結部材に対して位置を変位可能にして挟持固定できるようにしたことにある。これによると、マイクロフォンをより確実に固定することができるため、演奏者は使用しやすい角度にマイクロフォンを設置することができるようになる。この結果、マイクロフォンの使い勝手がよくなる。
【０００９】
【発明の実施の形態】
以下、本発明の一実施形態を図面を用いて説明する。図１は、同実施形態にかかる音楽演奏装置Ｍを示している。この音楽演奏装置Ｍは、音楽演奏装置本体１０と、マイクロフォン１１と、マイクロフォン１１を音楽演奏装置本体１０に取り付けるための保持装置２０とで構成されている。音楽演奏装置本体１０は、それぞれ複数の白鍵１２と黒鍵１３とからなる鍵盤１４を備えた電子鍵盤装置で構成されており、電源スイッチ（図示せず）をオン状態にして、白鍵１２と黒鍵１３とを順次押鍵操作することにより演奏を行うことができる。
【００１０】
マイクロフォン１１は、音楽演奏装置本体１０に接続して音声入力をすることが可能になっており、演奏者は、マイクロフォン１１を用いることにより音楽演奏装置本体１０を演奏しながら歌を歌うことができる。保持装置２０は外観が図２に示したように構成されており、図３に示した状態で、音楽演奏装置本体１０の任意の一方の側部１５または両側の側部１５（他方の側部は図示せず）に取り付け可能になっている。
【００１１】
保持装置２０は、音楽演奏装置本体１０の側部１５の内部側に取り付けられた取付部材２１と、取付部材２１に組み付けられる連結部材３０と、連結部材３０に組み付けられるホルダー部材４０と、連結部材３０を介してホルダー部材４０を取付部材２１に固定するための固定部材５０とで構成されている。取付部材２１は、図３および図４に示すように、断面形状が略Ｕ字状に形成された本体部２２と、一対の係合片２３ａ，２３ｂと、固定片２４とで構成されている。
【００１２】
本体部２２は、側部１５と平行して垂直に設けられた一対の支持片２２ａ，２２ｂと支持片２２ａ，２２ｂの下端縁部を連結する底部片２２ｃとで構成されている。そして、支持片２２ａの略中央には図３の左右方向に貫通する挿通穴２５が設けられている。挿通穴２５は、図５に示すように円形の周面の一部を係合用の平面部２５ａにした形状に形成されている。また、支持片２２ｂの略中央には、挿通穴２５よりも直径が小さく設定されたねじ穴２６が挿通穴２５と同軸的に設けられている。
【００１３】
一対の係合片２３ａ，２３ｂは、支持片２２ｂの下端部両側に支持片２２ｂから同一平面上に延長して設けられた小さな突起で構成されており、取付部材２１を側部１５の内部側に取り付ける際の位置決めに用いられる。また、固定片２４は、支持片２２ｂに対して直交して支持片２２ｂの外部側水平方向に延びるように支持片２２ｂの上端部に設けられている。固定片２４には、図３の上下方向に貫通するねじ挿通穴２７が設けられている。
【００１４】
また、音楽演奏装置本体１０の内部における取付部材２１が取り付けられる部分には、一対の取付片１６，１７が本体部２２の幅と略等しい間隔を保って設けられている。この取付片１６，１７は、音楽演奏装置本体１０と一体的に成形されており、上面部１８の下面から下方に向って平行に延びている。そして、取付片１６，１７の下端部には係合片２３ａ，２３ｂを係合させるための係合溝１６ａ，１７ａが設けられている。
【００１５】
したがって、取付部材２１は、係合片２３ａ，２３ｂを取付片１６，１７に係合させて位置決めされ、固定ねじ１９をねじ挿通穴２７に挿通させて上面部１８に固定させることにより、予め設定された上面部１８の所定の設定位置に取り付けられる。また、側部１５における支持片２２ａの挿通穴２５に対向する部分には、挿通穴２５よりもやや直径の大きな取付用穴部１５ａが設けられており、取付部材２１は、挿通穴２５およびねじ穴２６を取付用穴部１５ａと同軸的にした状態で上面部１８に取り付けられる。
【００１６】
連結部材３０は、側部１５の外部側から取付用穴部１５ａおよび挿通穴２５を挿通して側部１５および取付部材２１と係合する連結軸部３１と、連結軸部３１と一体的に形成された連結支持部３２とで構成されている。連結軸部３１は図６および図７に示すように、直径の大きな大径部３３と大径部３３の先端に形成された直径の小さな回転防止部３４とで構成され中心部にねじ挿通穴３５が形成されている。
【００１７】
そして、大径部３３の直径は、挿通穴２５の直径（平面部２５ａに略平行する最長部分の長さ）よりも大きく、取付用穴部１５ａの直径よりもやや小さくなるように設定され、回転防止部３４の断面形状は、図５に示した挿通穴２５の形状と略同一に設定されている。すなわち、回転防止部３４の側部の所定部分は、平面部２５ａと面接触する平面部３４ａに形成されている。なお、図５は、図３における支持片２２ａの表面に沿って切断した状態の断面を図示の左側から見た状態を示している。
【００１８】
また、連結支持部３２は、平行に設けられた略三角形の一対の板状体からなる支持片３２ａ，３２ｂと支持片３２ａ，３２ｂの下端縁部（図３の状態での下端）を連結する連結片３２ｃとで構成されており、支持片３２ａの略中央に大径部３３の端面が一体的に繋がっている。そして、支持片３２ａ，３２ｂの中央部には、それぞれねじ挿通穴３５と同径でかつ同軸的な挿通穴３６ａ，３６ｂが設けられている。したがって、連結部材３０を回転防止部３４側から取付用穴部１５ａ内に挿入すると、回転防止部３４は、取付用穴部１５ａを通過したのち支持片２２ａに達する。
【００１９】
このとき，回転防止部３４の平面部３４ａと挿通穴２５の平面部２５ａとの位置が一致していれば、回転防止部３４はそのまま挿通穴２５を通って進入していく。平面部３４ａと平面部２５ａとの位置が一致していなければ、連結部材３０を軸周りに回転させて平面部３４ａと平面部２５ａとの位置を一致させて回転防止部３４を挿通穴２５を通す。これによって、回転防止部３４は、先端部が支持片２２ｂに達するまで進む。
【００２０】
このとき、大径部３３と回転防止部３４との境界に形成された段状の端部が支持片２２ａに接触するように、支持片２２ａ，２２ｂの間隔および回転防止部３４の長さは設定される。また、この場合、平面部３４ａと平面部２５aとが接触することによって連結部材３０は軸周り方向への回転ができなくなっている。そして、連結支持部３２の連結片３２ｃは下方に位置して、支持片３２ａ，３２ｂの開放側は上方を向いた状態になる。また、支持片３２ｂの支持片３２ａと対向する面における挿通穴３６ｂの周囲には円形突部３７が設けられている。
【００２１】
ホルダー部材４０は、支持片３２ａ，３２ｂ間に位置決めされる被取付片４１とマイクロフォン１１を保持するためのマイク保持片４２とで構成されている。被取付片４１は、支持片３２ａ，３２ｂ間に挿入できる略三角形の板体で構成され、中央に挿通穴３６ａ，３６ｂと同径の取付穴４３が設けられている。そして、被取付片４１の一方の面における取付穴４３の周囲には、円形突部３７と係合可能な円形凹部４４が形成されている。この被取付片４１を支持片３２ａ，３２ｂ間に挿入して円形突部３７と円形凹部４４とを係合させた状態においては、ホルダー部材４０は連結部材３０に対して取付穴４３を中心として１８０度回転できる。
【００２２】
マイク保持片４２は、円筒体の側部の一部を軸方向に沿って取り除いて開放部４５にした形状に形成され、開放部４５に対向する部分の外側部が被取付片４１と一体的に繋がっている。解放部４５の幅は、マイクロフォン１１のコードを通せる長さに設定され、マイク保持片４２の直径は、マイクロフォン１１の中央胴部を挟持できる太さに設定されている。
【００２３】
固定部材５０は、先端にねじ５１が形成されたねじ棒５２と、固定部材５０を手で操作するための頭部５３とで構成されている。ねじ棒５２の直径は、挿通穴３６ａ，３６ｂ、取付穴４３およびねじ挿通穴３５を挿通できる大きさに設定され、先端のねじ５１はねじ穴２６に係合できるように形成されている。また頭部５３は、円形の締付け部５４を備えており、この締付け部５４にねじ棒５２の端部側部分が埋設固定されている。
【００２４】
固定部材５０は、連結部材３０を介して、ホルダー部材４０を取付部材２１に固定することができる。すなわち、図７のように、ホルダー部材４０の被取付片４１を支持片３２ａ，３２ｂ間に入れ、円形突部３７と円形凹部４４とを係合させる。そして、固定部材５０のねじ棒５２を挿通穴３６ａ，３６ｂ、取付穴４３およびねじ挿通穴３５に挿通させ、その状態で、連結部材３０を取付部材２１に組み付ける。
【００２５】
そして、ねじ棒５２のねじ５１をねじ穴２６に螺合によって係合させることにより、連結部材３０を介してホルダー部材４０を取付部材材２１に固定することができる。また、その際、締付け部５４を連結部材３０に押し付けることによって、樹脂製の支持片３２ａ，３２ｂを撓ませて被取付片４１を挟持させる。これによって、ホルダー部材４０の固定をより確実に行える。また、ホルダー部材４０は連結部材３０に対して軸周りに回転させることができるため、マイク保持片４２の向きを上下に調節することができる。そして、その状態のマイク保持片４２にマイクロフォン１１を取り付けて保持させることができる。
【００２６】
また、音楽演奏装置本体１０の他方の側部（図示せず）にも取付用穴部１５ａと同様の取付用穴部が設けられており、その内部側に取付部材２１と同様の取付部材が設けられている。ただし、この場合、他方の側部の取付部材は取付部材２１と左右対称に設けられ、連結部材３０の回転防止部３４を挿通させる挿通穴は、挿通穴２５の平面部２５ａが音楽演奏装置本体１０の前部（演奏者側）に位置しているのに対し、平面部を後部に位置させるようにして形成されている。このため、連結部材３０、ホルダー部材４０および固定部材５０はそのまま兼用できる。
【００２７】
また、音楽演奏装置本体１０の上面における鍵盤１４の近傍には、演奏に使用するための各種の操作子やスイッチが設けられており、音楽演奏装置本体１０の背面には、マイクロフォン１１やその他の機器を接続するためのコネクタ端子や切換スイッチ等が設けられている。さらに、音楽演奏装置本体１０の内部には、各種の基板やスピーカー等の装置が内臓されている。また、音楽演奏装置Ｍは、音楽演奏装置本体１０の両側部１５に形成された取付用穴部１５ａを塞ぐための栓（図示せず）を備えており、取付部材２１にホルダー部材４０等が取り付けられないときには、この栓で取付用穴部１５ａを塞いでおく。
【００２８】
このように構成した音楽演奏装置Ｍを演奏するときには、まず、図２に示したように、音楽演奏装置本体１０の一方の側部１５に、連結部材３０と固定部材５０を用いてホルダー部材４０を取り付ける。この場合、マイク保持片４２の向きをマイクロフォン１１を支持するために適した角度に調節して固定部材５０のねじ５１を取付部材２１のねじ穴２６の周面に係合させる。ついで、前述した各部材が組み付けられて構成された保持装置２０のマイク保持片４２に、図１のようにして、マイクロフォン１１を取り付ける。
【００２９】
そして、各種の操作子やスイッチを操作するとともに、鍵盤１４の各鍵１２，１３の押鍵操作を行うことによりメロディーや伴奏等の楽音を発音させる。また、同時にマイクロフォン１１に向って歌を歌うことによりその歌声をスピーカーを介して楽音とともに発音させることができる。また、マイクロフォン１１の角度を変更する際には、頭部５３を回転させることにより、連結部材３０による被取付片４１の挟持を弱め、ホルダー部材４０を、ねじ棒５２の軸回りに回転させる。そして、マイク保持片４２の角度が目的の角度になったところで、再度、ねじ５１とねじ穴２６の周面とを係合させてホルダー部材４０を固定する。
【００３０】
また、マイクロフォン１１を、音楽演奏装置本体１０の他方の側部に取り付ける場合には、栓を外して他方の側部の取付用穴部を開口させる。そして、図７に示したホルダー部材４０等の組み付け体を、前述した取付状態から水平方向に１８０度回転させた状態にして、他方の側部側に設けられた取付部材に固定する。これによりマイクロフォン１１を音楽演奏装置本体１０の他方の側部に取り付けることができる。
【００３１】
このように、本実施形態では、音楽演奏装置本体１０の側部１５側に取付部材２１を設け、この取付部材２１に、連結部材３０および固定部材５０を介してマイクロフォン１１を保持するためのホルダー部材４０を固定できるようになっている。したがって、演奏者は、音楽演奏装置本体１０を演奏するときに、同時にマイクロフォン１１使って歌を歌うことができる。また、ホルダー部材４０は上下方向に回転可能になっているため、演奏者は、適宜マイクロフォン１１の向きを任意の方向に変更することができる。このため、演奏者の体格の大きさに関係なく、演奏者が使用しやすい方向にマイクロフォン１１を向けることができる。
【００３２】
また、マイクロフォン１１を保持するための部材が、音楽演奏装置本体１０の内部に取り付けられた取付部材２１と、取付部材２１に対して着脱可能になった連結部材３０、ホルダー部材４０および固定部材５０とで構成されている。このように、少数でかつ小さな部材だけで済むため、部品点数が少なくなるとともに、コンパクトになるという利点を有する。また、取付部材２１が、音楽演奏装置本体１０の両側の側部１５に設けられ、双方の取付部材２１にホルダー部材４０等を組み付けることができるため、マイクロフォン１１の使い勝手がよくなる。この場合、両側の側部１５に設けられる取付部材２１は同形のものを使用できるため、部材の共通化が可能になる。
【００３３】
また、取付部材２１は、係合片２３ａ，２３ｂを介して上面部１８に固定された取付片１６，１７に取り付けられるため適正な位置に位置決めすることができる。このため、取付用穴部１５ａ、挿通穴２５およびねじ穴２６が同軸的になり、ねじ棒５２をそれらの穴に確実に通すことができる。また、挿通穴２５と回転防止部３４とで連結部材３０が回転することを防止しているため、マイクロフォン１１が不用意に回転することを防止できる。これによって、マイクロフォン１１の安定した保持ができる。
【００３４】
さらに、円形突部３７と円形凹部４４とを係合させて、ホルダー部材４０を連結部材３０に組み付けているため、ホルダー部材４０は連結部材３０に対して位置ずれすることなくスムーズに回転することができる。この結果、ホルダー部材４０と連結部材３０との係合状態が安定する。
【００３５】
また、前述した実施形態の構成については、適宜、変更実施が可能である。例えば、前記実施形態では、挿通穴２５に平面部２５ａを設けるとともに、回転防止部３４に平面部３４ａを設けて、取付部材２１に対して連結部材３０が回転しないようにしているが、この挿通穴や回転防止部の形状は、これに限らず、断面形状が円以外の形状になっていればよく、三角形や四角形等にすることもできる。また、連結部材３０は用いず、固定部材５０で直接ホルダー部材４０を側部１５に押し付けることにより固定することもできる。これによると、さらに部品点数が少なくなる。
【００３６】
また、前述した実施形態では、取付部材２１を固定ねじ１９によって音楽演奏装置本体１０の上面部１８に固定しているが、この取付部材２１は、音楽演奏装置本体１０と一体的に形成することもできる。さらに、前述した実施形態では、マイクロフォン１１をマイク保持片４２に着脱可能に取り付けるようにしているが、マイクロフォン１１とマイク保持片４２とを一体的に形成してもよい。
【００３７】
また、前述した実施形態では、固定部材５０がねじ棒５２を備えているが、この固定部材５０は、取付部材２１に対して捩じ込んだり、押し入れて係合させたりしてホルダー部材４０を固定するものでもよく、取付部材２１に対して着脱可能に固着できるものであればよい。さらに、前述した実施形態では、装着のし易さや状況に応じて反対側への装着ができることから、マイクロフォン１１を音楽演奏装置本体１０の側部１５に取り付けるようにしているが、マイクロフォン１１は、音楽演奏装置本体１０の側部１５以外の部分に取り付けることもできる。この場合、取付部材の設置位置は、マイクロフォン１１を取り付ける位置に応じて適宜変更する。
