Abstract: A control circuit and an electronic device are provided, to reduce power consumption of the electronic device. The electronic device includes a sensor and a control circuit. The sensor is configured to: detect a force or a deformation of a shell, and output a force sensing signal Sf. The control circuit is configured to: receive the force sensing signal Sf and determine, based on the force sensing signal Sf, whether to send a drive signal Sd to the sensor. The drive signal Sd is used to drive the sensor to drive the shell to vibrate. The sensor is further configured to: detect vibration of the shell and output a vibration sensing signal Sz. The control circuit is further configured to: receive the vibration sensing signal Sz, and determine, based on the vibration sensing signal Sz, whether to trigger an event.
