A speaker is provided to play a soft sound by making a property of matter of an inner circumference side and an outer circumference side of a vibrating plate similar. A speaker includes a magnetic circuit part(120), a vibrating part(130), and a reinforcing member(160). The magnetic circuit part is coupled in one surface of a frame, and generates a magnetic force. The vibrating part has a voice coil(131), a vibrating plate, an edge, and a damper. If a power source is applied, the voice coil is vibrated by operations with the magnetic circuit part. The vibrating plate is vibrated by the voice coil, and plays a sound. The reinforcing member is inserted to an inner circumference side of the vibrating plate. |
