Physical Quantity Sensor And Electronic Device

Abstract

Provided is a physical quantity sensor attached to an electronic device provided with an actuator. The physical quantity sensor includes: a sensor element configured to output a detection signal corresponding to a physical quantity; and a circuit device configured to output an actuator drive signal for driving the actuator based on the detection signal. The circuit device has a resonance characteristic measurement mode of outputting the actuator drive signal for measuring a resonance characteristic of the electronic device by vibrating the electronic device, and a vibration-damping mode of outputting the actuator drive signal for reducing a vibration of the electronic device based on the resonance characteristic measured in the resonance characteristic measurement mode.
