To adjust vibration to be transmitted to a vibration transmission section.SOLUTION: A notification device 1 includes: vibration signal conversion means 40 which converts input vibration transmitted to a vibration transmission section 201 from the outside into a detection signal, converts a vibration signal into notification vibration, and transmits the vibration to a vibration transmission section 201; resonance frequency detection means 50 which determines a frequency characteristic of the detection signal and detects a resonance frequency; and vibration signal generation means 20 which generates a vibration signal including the resonance frequency. The vibration signal generation means 20 outputs the vibration signal including the resonance frequency to the vibration signal conversion means 40. The vibration signal conversion means 40 converts the vibration signal including the resonance frequency into notification vibration and transmits the vibration to the vibration transmission section 201.SELECTED DRAWING: Figure 1
【課題】振動伝達部に伝達される振動を調整すること。【解決手段】報知装置1は、外部から振動伝達部201に伝達された入力振動を検出信号に変換し、且つ、振動信号を報知振動に変換して振動伝達部201に伝達する振動信号変換手段40と、検出信号の周波数特性を求めて共振周波数を検出する共振周波数検出手段50と、共振周波数を含む振動信号を生成する振動信号生成手段20とを有する。振動信号生成手段20は、共振周波数を含む振動信号を振動信号変換手段40へ出力し、振動信号変換手段40は、共振周波数を含む振動信号を報知振動に変換して振動伝達部201に伝達する。【選択図】 図1
