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; a memory configured to store a resonance characteristic of the electronic device; a signal output circuit configured to output an actuator drive signal for driving the actuator to reduce a vibration corresponding to the resonance characteristic included in vibrations of the electronic device indicated by the detection signal; and an interface circuit configured to rewrite the resonance characteristic stored in the memory according to an external signal.
