To suppress sound leakage following vibration of vibrators in a case where a portion of the plurality of vibrators that is provided on a seat and can emit sound is not in contact with a seating person.SOLUTION: A vibration transmission device 10 for a seat comprises: a plurality of vibrators Q1-Q4 which is provided on a seat 280 and can emit the sound; a drive part 270 which can individually drive each of the plurality of vibrators; sensors SE1-SE4 which detect contact/non-contact of the body of a seating person for at least a portion of the plurality of vibrators; and a control part 200 which can control the vibration mode of the vibrator on the basis of a detection signal of the sensor. The control part 200 shifts the vibrator that is turned into the non-contact state to the vibration state where sound leakage more hardly occurs from the vibration state before it is turned into the non-contact state or shifts the vibrator that is turned into the non-contact state to the non-vibration state.SELECTED DRAWING: Figure 3

    【課題】 シートに設けられた、音を発することが可能な複数の振動体の一部が着座者と非接触になった場合における、その振動体の振動に伴う音漏れを抑制する。【解決手段】 シート用振動伝達装置10は、シート280に設けられる、音を発することが可能な複数の振動体Q1~Q4と、複数の振動体の各々を個別に駆動可能な駆動部270と、複数の振動体のうちの少なくとも一部の振動体についての、着座者の身体の接触/非接触を検出するセンサSE1~SE4と、センサの検出信号に基づいて、振動体の振動態様を制御可能な制御部200と、を有し、制御部200は、非接触状態となった振動体を、非接触となる前の振動状態から、音漏れがより生じにくい振動状態へと移行させる、又は、非接触状態となった振動体を、非振動状態とする。【選択図】 図3
