Abstract
Provided is a bone conduction earphone that includes a main body, and a bone conduction speaker and a passive radiator that are mounted on the main body. The passive radiator is connected to the bone conduction speaker through a connecting rod. When vibrating by being excited by an audio signal, the bone conduction speaker drives the passive radiator to vibrate synchronously through the connecting rod. The passive radiator and the bone conduction speaker cooperate with each other to form a multi-vibration system, thereby effectively enhancing the quality of vibration, improving the effect of sound field radiation, and improving the frequency response, especially remedying the deficiencies in low-frequency response.
