PROBLEM TO BE SOLVED: To realize mechanical vibration modulation having a fixed amplitude independent from a frequency in order to moderate a request to a mount (mounting system), to attain the optimum gain, and to attain the fixed optimum response speed. SOLUTION: A method and a device for modulating vibration of an object with a fixed amplitude have an piezoelectric transducer 212 for sensing vibration. An LED 216 receives a sensed signal and irradiates a light dependent resistor(LDR) R9. A control circuit controls the vibration amplitude corresponding to the resistance of the LDR. A full-wave bridge rectifier 214 can be used between a sensor and the LED. |
