- オーディオ信号によって動作して被加振体を所定方向に加振することで発音させる加振器の取付構造であって、
固定支持部に対して固定状態とされ、磁路を形成する磁路形成部と、
前記磁路形成部に電磁的に係合する電磁係合部を有し、ダンパによって支持され、オーディオ信号に基づく駆動信号が入力されると前記磁路形成部により前記電磁係合部が励振されて前記所定方向に振動する可動体と、
前記被加振体に固定され、前記可動体を前記被加振体に対して連結して前記可動体の振動を前記被加振体に伝達する連結部と、
前記ダンパとは別に前記固定支持部に対して固定状態とされると共に、前記所定方向における前記ダンパとは異なる位置で前記可動体に係合し、前記可動体の、前記所定方向への移動を許容しつつ前記所定方向と交わる方向への移動を係合位置で規制する少なくとも1つの規制手段とを有し、
前記規制手段は、繊維部材または弾性部材でなる接触部材を有し、該接触部材が前記可動体と接触して前記所定方向と交わる方向への前記可動体の移動を規制し、
さらに、前記ダンパ及び前記規制手段がそれぞれ係合する前記可動体の位置のうち前記連結部に最も近い側の係合位置から、前記被加振体までの間において、前記可動体または前記連結部に設けられた許容機構を有し、
前記許容機構は、前記固定支持部に対して相対的に前記連結部が所定範囲内で変位したとしても、少なくとも前記可動体における前記接触部材と接触する部分が前記所定方向に対して傾斜することを許容するように構成されることを特徴とする加振器の取付構造。 - 前記規制手段は、前記所定方向における前記被加振体よりも前記磁路形成部に近い位置で前記可動体と係合することを特徴とする請求項1記載の加振器の取付構造。
