PROBLEM TO BE SOLVED: To make operation sound of a switch installed in a cabin hardly recognizable as noise.SOLUTION: A switch 2 outputs a signal in response to operation from a user. A characteristic acquisition unit 3 acquires F-S characteristics of the switch 2 associated with the operation from the user. A control unit 5 causes a loudspeaker 4 to output sound containing frequency components for suppressing operation sound generated through the operation of the switch 2 on the basis of the F-S characteristics acquired by the characteristic acquisition unit 3.SELECTED DRAWING: Figure 1

    【課題】車室内に配置されたスイッチの操作音をノイズとして認識されにくくする。【解決手段】スイッチ2は、ユーザの操作に応じて信号を出力する。特性取得部3は、ユーザの操作に伴うスイッチ2のF−S特性を取得する。制御部5は、特性取得部3により取得されたF−S特性に基づいて、スイッチ2の操作に伴って発生する操作音を抑制する周波数成分を含む音をスピーカー4から出力させる。【選択図】図1
