Abstract
A headphone and an electronic device are provided. The headphone includes a gyroscope, which senses a bone conduction vibration and provides a quadrature error signal for reflecting the bone conduction vibration. Specifically, the headphone includes a transmission assembly that acts directly or indirectly on the gyroscope or an inertial measurement unit (IMU) including the gyroscope. The transmission assembly transmits the bone conduction vibration to the gyroscope to make the gyroscope strain, thereby causing the quadrature error signal of the gyroscope to change to detect the bone conduction vibration with sensitivity.
