PURPOSE: A speaker is provided to improve a tone quality by preventing the deformation of a sound generating part. CONSTITUTION: A magnetic circuit part(120) is combined in one-side of a frame(110). The magnetic circuit part generates a magnetic force. A sound generation part(130) comprises a voice coil(131), a damper, and a vibration plate(137). The voice coil has a bobbin(132) and a coil. The voice coil is operated by the magnetic circuit part is vibrated. A damper supports the vibration of the voice coil. The vibration plate generates a sound. A supporting member is formed on inner side of the damper. The supporting member prevents the deformation of a longitudinal direction part of the voice coil. |
