【０００１】
【発明の属する技術分野】
本発明は、音発生手段から音源信号を機械的振動に変換する変換器を備え、変換器の振動によって人体の一部を振動させる体感音響装置に関するものである。
【０００２】
【従来の技術】
従来から、音発生手段から送られてきた信号を機械的振動に変換し、この振動により人体を振動させる例えば特開２００１−２１２１９８号公報記載のリラクゼーション用椅子のような体感音響装置が知られている。上記のような体感音響装置はＣＤプレーヤのような音発生手段から送られた音を制御する音制御装置と、音制御装置から出力される音響信号を振動に変換する変換器と、変換器に設けた変換器の振動により人体の一部を振動させる連動部材とを有している。
【０００３】
上記構成を有する体感音響装置は、音発生手段から送られた音を変換器の振動に変換して連動部材を振動させ、これにより体感者の体の一部に音に同調した臨場感のある心地良い振動を伝えていた。
【０００４】
しかしながら、上記の体感音響装置は、一つの変換器に対して一つの連動部材を設けているため、体感者の体の複数の部位に振動を伝えようとした場合、振動させる人体の部位の数だけ変換器を設けなければならず、これにより体感音響装置のコストが高くなってしまうという問題があった。
【０００５】
【発明が解決しようとする課題】
本発明は上記の点に鑑みてなされたものであり、その目的とするところは、体感者の多くの部位に振動を伝えることができ、且つコストのかからない体感音響装置を提供することを課題とするものである。
【０００６】
【課題を解決するための手段】
上記課題を解決するために本発明に係る体感音響装置は、音発生手段から送られてくる信号を機械的振動に変換する変換器３を備え、該変換器３に変換器３の振動によって人体の一部を振動させる連動部材４を設けた体感音響装置１において、１つの変換器３に対して２つ以上の連動部材４を設けて成ることを特徴とするものである。
【０００７】
このように複数の連動部材４を設けることで体感者９の体の多くの部位に振動を伝えることができるのはもちろんのこと、体感音響装置１に連動部材４を設ける数に対して変換器３を設ける数を少なくすることができる。
【０００８】
また請求項２記載の体感音響装置は請求項１記載の体感音響装置において、上記連動部材４を管状に形成したことを特徴とするものである。
【０００９】
このように連動部材４を管状に形成することで、連動部材４の剛性を保つことができ、またこれによって体感者９に安定して振動を伝えることができる。
【００１０】
また請求項３記載の体感音響装置は請求項１又は２記載の体感音響装置において、変換器３と連動部材４とを変換器３の振動方向イと平行に伸びる振動伝播体５ｂを介して接続して成ることを特徴とするものである。
【００１１】
変換器３と連動部材４とを変換器３の振動方向イと平行に伸びる振動伝播体５ｂを介して接続したことで、変換器３の振動を効率良く連動部材４に伝えることができる。
【００１２】
また請求項４記載の体感音響装置は請求項１〜３のいずれかに記載の体感音響装置において、上記体感音響装置１は少なくとも体感者の腰部９ａを振動させる連動部材４ａと、膝の裏側部分９ｂを振動させる連動部材４ｂとを有して成ることを特徴とするものである。
【００１３】
このように構成することで、骨盤のある腰部９ａを振動させて骨振動を行うことができると共に触覚が敏感な膝の裏側部分９ｂを振動させることができ、これにより体感者９に対して数少ない連動部材４で全身が振動されているイメージを与えることができる。
【００１４】
また請求項５記載の体感音響装置は請求項４記載の体感音響装置において、腰部９ａを振動させる連動部材４ａと変換器３との間の距離が膝の裏側部分９ｂを振動させる連動部材４ｂと変換器３との間の距離よりも短くなるように設定して成ることを特徴とするものである。
【００１５】
このような構成を有することで、強い振動が必要な腰部９ａを振動させる連動部材４ａを強く振動させると共に弱い振動でも充分振動感が得られる膝の裏側部分９ｂを振動させる連動部材４ｂを弱く振動させることができ、また腰部９ａの振動と膝の裏側部分９ｂの振動とに振動伝達による時差を生じさせることができる。
【００１６】
また請求項６記載の体感音響装置は請求項１〜５のいずれかに記載の体感音響装置において、上記体感音響装置１は体感者９が着座するための座部２４を有し、該座部２４は臀部を支持するための臀部支持体２４０と臀部支持体２４０に設けられたクッション用ばね２４１とを有し、座部２４に着座した体感者９の臀部をクッション用ばね２４１を介して臀部支持体２４０で支持して成ることを特徴とするものである。
【００１７】
このように体感音響装置１は座部２４を有することで、体感者９が座部２４に着座したリラックスした状態で連動部材４の振動を受けることができるのはもちろんのこと、尚且つ座部２４はクッション用ばね２４１を有しているので、座り心地が良くなり、体感者９はより一層リラックスした状態で連動部材４の振動を受けることができる。
【００１８】
また請求項７記載の体感音響装置は請求項６記載の体感音響装置において、上記体感音響装置１は体感者９の膝の裏側部分９ｂを振動させる連動部材４ｂを有し、この連動部材４ｂと変換器３とをクッション用ばね２４１の下方に位置する振動伝播体５ｂを介して接続し、体感音響装置１に振動伝播体５ｂとクッション用ばね２４１との間に位置する弾性部材６を配設して成ることを特徴とするものである。
【００１９】
上記のように膝の裏側部分９ｂを振動させる連動部材４ｂと変換器３とをクッション用ばね２４１の下方に位置する振動伝播体５ｂを介して接続することで、体感者９が着座した際に振動伝播体５ｂが邪魔にならず、尚且つ振動伝播体５ｂとクッション用ばね２４１との間に位置する弾性部材６を設けることで、体感者９が勢い良く座部２４に着座したり、体重の重い体感者９が座部２４に着座したりする等してクッション用ばね２４１と振動伝播体５ｂとが接触したとしても、接触による異音の発生や振動伝播体５ｂの変形を弾性部材６により防止することができる。
【００２０】
また請求項８記載の体感音響装置は請求項１〜７のいずれかに記載の体感音響装置において、上記体感音響装置１に体感者９が着座するための座部２４及び該座部２４に着座した体感者の背中をもたれさせるための背もたれ部２３とからなる椅子２を有し、この椅子２に変換器３と変換器３の振動により椅子２に着座した人の体の一部を振動させる連動部材４を設け、変換器３もしくは連動部材４のうちの少なくとも一つを連結ばね７を介して椅子２に設けて成ることを特徴とするものである。
【００２１】
上記のように背もたれ部２３を設けることで体感者９は背もたれ部２３にもたれてよりリラックスした状態で着座して振動を受けることができ、尚且つ変換器３もしくは連動部材４のうちの少なくとも一つを連結ばね７を介して椅子２に設けることで、変換器３もしくは連動部材４の振動が椅子２に伝わることを防止することができる。
【００２２】
また請求項９記載の体感音響装置は請求項８記載の体感音響装置において、上記連結ばね７と椅子２との接続部分に音軽減部材８を設けて成ることを特徴とするものである。
【００２３】
このように連結ばね７と椅子２との接続部分に音軽減部材８を設けることで、変換器３もしくは連動部材４の振動によって発生する連結ばね７と椅子２との接続部分での軋み音の発生を抑えることができる。
【００２４】
また請求項１０記載の体感音響装置は請求項１〜９のいずれかに記載の体感音響装置において、上記体感音響装置１は体感者９が着座するための座部２４及び該座部２４に着座した体感者の背中をもたれさせるための背もたれ部２３とからなる椅子２を有し、座部２４及び背もたれ部２３は夫々体感者９の臀部を支持する臀部支持体２４０と背中を支持する背中支持体２３０とを有し、この体感音響装置１に変換器３の振動により椅子２に着座した人の体の一部を振動させる連動部材４を臀部支持体２４０もしくは背中支持体２３０よりも体感者側に位置するように配設して成ることを特徴とするものである。
【００２５】
上記のように連動部材４を臀部支持体２４０もしくは背中支持体２３０よりも体感者９側に位置するように配設することで、連動部材４を体感者９により強く押し当てることができる。
【００２６】
【発明の実施の形態】
本発明の添付図面に示す実施形態に基づいて説明する。本実施形態における体感音響装置１は体感音響装置１外部のＣＤプレイヤーやテレビジョン、パーソナルコンピュータのような音発生手段（図示せず）に電気的に接続して使用されるものである。なお、音発生手段は体感音響装置１に設けてあっても良いものとする。該体感音響装置１は図示は省略するが音発生手段に接続されると共に音発生手段から送られてきた音を制御するための音制御装置を有している。音制御装置には音制御装置に設けられた図示しない入力端子や接続コードを介して電気的に接続されると共に音制御装置から送られてくる音響信号を機械的振動に変換する、すなわち音発生手段から送られてくる信号（電気信号）を機械的振動に変換するトランスデューサーのような変換器３と、変換器３の振動によって人体の一部である腰部及び膝の裏側部分９ｂを振動させる連動部材４とを有している。以下具体的構成について説明する。
【００２７】
上記体感音響装置１は人（以下体感者９と称す）が着座してリラックスした状態で連動部材４の振動を受けることができるよう主体を図４に示すような椅子２で構成している。
【００２８】
椅子２の骨組みは図１〜３に示すように床面に載置されるベースフレーム２１と、ベースフレーム２１後端部に接続されると共に体感者９の背中を支持するための背もたれ部用フレーム２３０と、後端部が背もたれ部用フレーム２３０に接続され前端部がベースフレーム２３０に接続されると共に体感者９の臀部を支持するための座部用フレーム２４０と、背もたれ部用フレーム２３０の上端に設けられると共に体感者９の頭部を支持するための枕部用フレーム２２０と、後端部が背もたれ部用フレーム２３０に接続されると共に体感者９の肘を支持するための肘掛け部用フレーム２５０とで構成されている。各フレーム２１、２３０、２４０、２２０、２５０にはクッション材（図示せず）と、このクッション材を覆う表皮２０とが設けられており、これによって椅子２に図４に示すような、背もたれ部用フレーム２３０を有する背もたれ部２３と、枕部用フレーム２２０を有する枕部２２と、座部用フレーム２４０を有する座部２４と、肘掛け部用フレーム２５０を有する肘掛け部２５とを形成する。なお図中２６は音制御装置をコントロールする操作部である。
【００２９】
ベースフレーム２１は横フレーム部２１０ａと横フレーム部２１０ａの前端部から上後方に延設された傾斜フレーム部２１０ｂとからなる一対の略Ｌ字状枠部２１０、２１０と、幅方向に間隔を隔てて平行に配置された一対の略Ｌ字枠部２１０の夫々の横フレーム部２１０ａの前部及び後部同士を連結する前連結フレーム部２１１及び後連結フレーム部２１２とからなる。
【００３０】
背もたれ部用フレーム２３０は、ベースフレーム２１の後連結フレーム部２１２の幅方向に間隔を隔てた箇所に接続された略上方に伸びる一対の縦フレーム部２３０ａと、両縦フレーム部２３０ａ、２３０ａの上部同士を接続する幅方向中央部が後方に位置するように湾曲した湾曲フレーム部２３０ｃとで構成されている。両縦フレーム部２３０ａ、２３０ａは上部が後方に位置する後傾となるように形成されており、体感者９が椅子２に着座した際にリラックスした姿勢でもたれられるようになっている。
【００３１】
枕部用フレーム２２０は前記両縦フレーム部２３０ａ、２３０ａの上端部同士を接続しており、幅方向中央部が後方に位置するように湾曲している。枕部用フレーム２２０の両端部は略前方に向かって延設されており、両端部にスピーカー保持フレーム部２２０ａを形成している。両スピーカー保持フレーム部２２０ａ、２２０ａの幅方向の間隔は前方に行く程離れるように形成されており、両スピーカー保持フレーム部２２０ａ、２２０ａには椅子２に着座した体感者の耳に向かう方向に配設されると共に図示しない増幅器等に電気的に接続されたスピーカー２２１が夫々設けられている。
【００３２】
上記両縦フレーム部２３０ａ、２３０ａの下部には前方に突出すると共に平面視において中央に開口を有する略ロ字状の座部用フレーム２４０を設けている。座部用フレーム２４０は、幅方向の内側端部が両縦フレーム部２３０ａ、２３０ａの下部に接続された一対の後部支持フレーム部２４０ａと、両後部支持フレーム部２４０ａ、２４０ａの幅方向の外側端部から前方に向かって延設された側部支持フレーム部２４０ｂ、２４０ｂと、両側部支持フレーム部２４０ｂ、２４０ｂの前端部同士を接続する前部支持フレーム部２４０ｃとから成り、両側部支持フレーム部２４０ｂの夫々の前端部の外側面はベースフレーム２１の傾斜フレーム部２０ｂの上部に接続されている。両側部支持フレーム部２４０ｂの前後方向における中央部から後部までの上面にはクッション用ばね２４１の両端部が接続されており、該クッション用ばね２４１は座部用フレーム２４０の開口の前後方向における中央部から後部までを覆うように配設されている。上記のように座部２４を構成する座部用フレーム２４０にはクッション用ばね２４が設けられているため、座り心地が良くなり、体感者９はより一層リラックスした状態で着座できる。
【００３３】
両縦フレーム部２３０ａ、２３０ａの上下方向における略中央部には平面視前向きコ字状の肘掛け部用フレーム２５０の後部が接続されており、この肘掛け部用フレーム２５０は体感者９が椅子２に着座した際にリラックスした姿勢でもたれられるように上方に行く程後方に位置するように傾斜している。
【００３４】
上記椅子２の体感者９が着座した際の腰部９ａ背面に位置する箇所には、円盤状の変換器３と、該変換器３に変換器３の周側面前部を覆うように固定して設けられた正面視四角形状（長方形状）を有する板状の腰部連動部材４ａとが配設されている。変換器３及び腰部連動部材４は図５に示すように両縦フレーム部２３０、２３０の傾斜と略平行に配設されており、変換器３及び腰部連動部材４の面と直行する方向（矢印イ）に振動する。
【００３５】
具体的には腰部連動部材４ａは図１〜３に示すように両端にフック部７０、７１を有する複数の連結ばね７ａ（４つ）を介して前述した背もたれ部腰フレーム２３０に連結されることで調節支持されている。すなわち、腰部連動部材４ａの背面の外周縁部に設けた複数（４つ）のばね接続部４０に連結ばね７ａの一端のフック部７０を接続すると共に両縦フレーム部２３０ａ、２３０ａの前後方向略中央部に設けた複数（４つ）のばね接続部２３０ｂに連結ばね７ａの他端のフック部７１を接続することで、変換器３及び連動部材４を体感者９が着座した際の腰部９ａ背方に位置する箇所に張設支持している。
【００３６】
このように腰部連動部材４ａを連結ばね７ａを介して椅子２の背もたれ部用フレーム２３０に設けることで、腰部連動部材４ａから背もたれ部用フレーム２３０に伝わる振動を減衰させることができ、延いては椅子２の骨格である枕部用フレーム２２０、背もたれ部用フレーム２３０、座部用フレーム２４０、肘掛け部用フレーム２５０に振動が伝わることがなくなり、これにより振動を受けると不快に感じてしまう体感者９の頭部や肘などの部位に腰部連動部材４ａの振動が伝播してしまうことを防止できる。また上記では変換器３に連動部材４を直接固定しているので、変換器３もしくは連動部材４のどちらか一方を保持するだけで良く、変換器３と連動部材４の両方を別々に保持する場合と比して構造が簡単になりコストの削減になる。
【００３７】
上記各連結ばね７ａの他端部側のフック部７１の背もたれ部用フレーム２２０の各ばね接続部２３０ｂとの接続部分（接触部分）には音軽減部材８としてのチューブが設けられている（図３（ｂ）参照）。これにより連動部材４ａの振動によって発生する連結ばね７ａと背もたれ部用フレーム２２０のばね接続部２３０ｂとの接続部分での軋み音の発生を抑えることができる。なお、本実施形態においては連結ばね７ａに音軽減部材８を設けた例を示したが、もちろん背もたれ部用フレーム２２０の各ばね接続部２３０ｂの連結ばね７ａのフック部７１との接続部分に音軽減部材８を設けても良いものである。さらに上記では音軽減部材８としてチューブを使用した例を示したが、これに限定されるものではなく、従来から知られている種々の音軽減部材８を用いても良く、例えば連結ばね７ａもしくはばね接続部２３０ｂの接続部分を合成樹脂等で表面コーティングし、これを音軽減部材８としても良いものである。
【００３８】
また、上記の腰部連動部材４ａは連結ばね７ａの長さや弾性力、背もたれ部用フレーム２３０や腰部連動部材４ａのばね接続部２３０ｂ、４０の設ける位置を調節することにより、図５に示すように腰部連動部材４ａが縦フレーム部２３０ａ、すなわち背もたれ部用フレーム２３０よりも体感者側（変換器３の振動方向イにおける略前方向）に突出した位置に配設されている。これによって連動部材４を体感者９の腰部９ａにより強く押し当てることができ、連動部材４の振動を体感者９に効率良く伝えることができる。
【００３９】
上記変換器３（腰部連動部材４ａであっても良いものとする）には膝の裏側部分９ｂに対応する箇所に位置すると共に側断面略楕円形状を有する管状に形成された膝裏連動部材４ｂが振動伝播部材４を介して接続されている。すなわち、１つの変換器３に対して２つの連動部材４である腰部連動部材４ａと膝裏連動部材４ｂとを設けていることとなり、更に言うと腰部連動部材４ａと変換器３との間の距離は膝裏連動部材４ｂと変換器３との間の距離よりも短くなるように配設されていることとなる。
【００４０】
詳述すると、上記膝裏連動部材４ｂは前述の座部用フレーム２４０の両側部支持フレーム部２４０ｂに設けたばね接続部２４０ｄに連結ばね７ｂを介して連結されている。すなわち、膝裏連動部材４ｂの幅方向両端の下面に設けた複数（２つ）のばね接続部４１に連結ばね７ｂの一端のフック部７２を接続すると共に座部用フレーム２４０の両側部支持フレーム部２４０ｂ、２４０ｂの前部に設けた複数（２つ）のばね接続部２４０ｄに連結ばね７ｂの他端のフック部７３を接続することで、膝裏連動部材４ｂを体感者９が着座した際の膝の裏側部分９ｂに近接する箇所に保持している。上記膝裏連動部材４ｂはクッション用ばね８に接しないように配設されている。なお、前述した腰部連動部材４ａと背もたれ部用フレーム２３０とを接続する連結ばね７ａと同様に、この膝裏連動部材４ｂと臀部支持体２４０とを連結する各連結ばね７ｂの他端のフック部７１と臀部支持対２４０のばね接続部２４０ｄとの接続部分に音軽減部材８を設けても良いものである。
【００４１】
上記のように膝裏連動部材４ｂを座部用フレーム２４０に連結ばね７ｂを介して配設することで、膝裏連動部材４ｂから座部用フレーム２４０に伝わる振動を減衰させることができ、延いては椅子２の骨格である枕部用フレーム２２０、背もたれ部用フレーム２３０、座部用フレーム２４０、肘掛け部用フレーム２５０に振動が伝わることがなくなり、これにより体感者９の振動を受けると不快に感じてしまう頭部や肘などの部位に膝裏連動部材４ｂの振動が伝播してしまうことをより一層防止できる。
【００４２】
振動伝播部材５は、図１〜３、図５に示すように上端部が変換器３の下端部（腰部連動部材４ａの背面下部であっても良い）に接続され且つこの上端部から背もたれ部用フレーム２３０の傾斜に沿った方向における略下方に伸びる後振動伝播体５ａと、後振動伝播体５ａの下端から略前方の変換器３の振動方向イと平行な方向に延設された横振動伝播体５ｂと、横振動伝播体５ｂの前端部から略上向きに延設された前振動伝播体５ｃとから成る。上記横振動伝播体５ｂはクッション用ばね２４１の下方に位置しており、さらに言うと振動伝播部材５はクッション用ばね８に接しないように配設されている。このように振動伝播部材５を配設することで、体感者９が着座した際に振動伝播部材５が邪魔にならず、また振動伝播部材５を座部２４もしくは背もたれ部２３で隠すことができ外観が美しくなる。また、上記では変換器３と膝裏連動部材４ｂとを変換器３の振動方向イと平行に伸びる横振動伝播体５ｂを介して接続しており、これにより変換器３の振動を離れた連動部材４である膝裏連動部材４ｂに効率良く伝えることができる。
【００４３】
また、横振動伝播体５ｂとクッション用ばね２４１との間に位置する箇所である横振動伝播体５ｂの上面には図６に示すように弾性部材６を設けている。これにより体感者９が勢い良く座部６に着座したり、体重の重い体感者９が座部６に着座したりする等してクッション用ばね２４１が下方に下がったとしても、クッション用ばね２４１と横振動伝播体５ｂとは弾性部材６を介して接触することとなり、クッション用ばね２４１と横振動伝播体５ｂとの接触による異音の発生や振動伝播部材４の変形を防止することができる。
【００４４】
上記の膝裏連動部材４ｂは連結ばね１２ｂの長さや弾性力、ばね接続部３ｄ、７ｄの設ける位置を調節することにより、座部用フレーム２４０よりも体感者側（上方）に位置するように配設されている。これによって膝裏連動部材４ｂを体感者９の膝の裏側部分９ｂにより強く押し当てることができ、連動部材４の振動を体感者９に効率良く伝えることが可能となる。
【００４５】
次に音発生手段から送られてくる音の制御について説明すると、音発生手段から出力された音は音制御装置を介し、一部は増幅器等を通りスピーカー２２１より流れる。また、一部は図示しないローパスフィルタによって音発生手段から送られてきた音の高域をカットして音源信号となり、該音源信号は増幅器によって増幅されて振動用音響信号となり、この振動用音響信号を変換器３にて機械的振動に変換し、変換器３を振動させる。変換器３の振動は変換器３に接続された連動部材４を振動させ、これにより音発生手段に同調した臨場感のある振動を体感者９の腰部９ａ及び膝の裏側部分９ｂに伝えている。なお、本実施形態における体感音響装置１は音制御装置とローパスフィルタと増幅器を設け、変換器を音響信号から機械的振動に変換した例を示したが、これに限定されるものではなく、例えば体感音響装置に音制御装置、ローパスフィルタ、増幅器を設けず、音発生手段から出力された信号を直接機械的振動に変換する変換器３を設けても良いものとする。
【００４６】
ところで本実施形態における体感音響装置１は前述したように１つの変換器３に対して２つの連動部材４を設けているが、これは以下に示すような理由による。すなわち、１つの変換器３に対して２つの連動部材４を設けることで、連動部材４を設ける数に対して体感音響装置１に変換器３を設ける数を少なくすることができ、これにより体感音響装置１のコストを下げることができるのである。なお、本実施形態では体感音響装置１に１つの変換器３と、２つの連動部材４を設けた例を示したが、これに限定されるものではなく、例えば１つの変換器３に対して２つ以上の連動部材４を設けても良く、さらに言うと２つ以上のＮ個の変換器にＮ＋１個以上の連動部材４を設けても良いものとする。
【００４７】
また上記では前述したように腰部連動部材４ａと膝裏連動部材４ｂとを設けているので、骨盤のある腰部９ａを振動させて骨振動を行うことができると共に触覚が敏感な膝の裏側部分９ｂを振動させることができ、これにより体感者９に対して数少ない連動部材４で全身が振動されているイメージを与えることができる。
【００４８】
さらに上記では腰部連動部材４ａと変換器３との間の距離が膝裏連動部材５ｂと変換器３との間の距離よりも短くなるように配設しているので、強い振動が必要な腰部９ａを振動させる腰部連動部材４ａを強く振動させると共に弱い振動でも充分振動感が得られる膝の裏側部分９ｂを振動させる膝裏連動部材４ｂを弱く振動させることができ、これにより体感者の腰部９ａと膝の裏側部分９ｂとをバランス良く振動させることができ、また腰部９ａの振動と膝の裏側部分９ｂの振動とに振動伝達による時差を生じさせることができる。
【００４９】
また上記では膝裏連動部材４ｂを管状に形成しているので、図７に示すような板状に形成された膝裏連動部材４ｂと比して膝裏連動部材４ｂの剛性を保つことができ、これによって体感者に安定して振動を伝えることができる。また特に膝裏連動部材４ｂの側断面を略楕円形状としたことで、体感者９と膝裏連動部材４ｂとの接触面積を下げることができ、これにより強い力で振動させることが可能となる。なお上記では膝裏連動部材４ｂを管状に形成した例を示したが、その他の連動部材４を管状に形成しても良いものであり、例えば腰部振動体３ａを管状に形成しても良く、この場合においても上記と同様の作用効果が得られるものである。また上記では膝裏連動部材４ｂの側断面形状を楕円形状としたが、これに限定されるものではない。特に上記連動部材４を円管状に形成することが好ましく、この場合体感者９と連動部材４との接触面積をより一層下げることができ、これによりさらに強い力で体感者９の体の部位を振動させることが可能となる。
