PURPOSE: A bone conduction earphone is provided to expend the watch band by additionally forming the other external computing device vibration pipe on the outside of a silicone cover. CONSTITUTION: A voice coil is installed on inside of a frame(17) and forms the magnetic field according to an electric signal. At least a pair of magnets vibrates as constant frequency according the magnetic field of the voice coil. A vibrator transfers the vibration of magnet to the human body. A housing(10) is formed in the end part of one side of frame. Inducing the resonance of the air according to the vibration of the vibrator, a cover(13) is comprised of the silicon material of the soft which multiplies the sound volume. An air layer is formed between the silicon material of cover and vibrator. An external computing device vibration pipe(14) is connected to the vibrator. |
