Touch key assembly, control circuit, and electronic device

An electronic device, comprising a sensor and a control circuit, wherein

• 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 generate a drive signal Sd, wherein the drive signal Sd is used to drive the shell to vibrate;
• the sensor is further configured to:
• detect vibration of the shell and output a vibration sensing signal Sz;
• and
• 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.

A control circuit, wherein

• the control circuit is configured to receive a force sensing signal Sf output by a sensor, wherein the force sensing signal Sf indicates a force or a deformation detected by the sensor;
• the control circuit is further configured to determine, based on the force sensing signal Sf, whether to send a drive signal Sd to the sensor, wherein the drive signal Sd is used to drive the sensor to vibrate;
• and
• the control circuit is further configured to:
• receive a vibration sensing signal Sz sent by the sensor, and determine, based on the vibration sensing signal Sz, whether to trigger an event, wherein the vibration sensing signal Sz is a response signal of the vibration.
