PURPOSE: An electric hair clipper is provided to offset noise by installing a silencer which generates artificial sound with the inverse phase and the same amplitude with the noise generated from a power transmission gear group or a drive motor. CONSTITUTION: An electric hair clipper comprises a motor blade, a motor chamber(20), a silencer(30), a music player, and a power supply device(50). The motor blade cuts hair with an external fixed blade and a movable blade. The motor chamber comprises a drive motor(M) and a power transmission gear group. The silencer is installed on one side of the motor chamber. The silencer reduces the noise of the power transmission gear group and the drive motor. The music player reproduces the music in the external input. |
