PURPOSE: A speaker is provided to simplify an assembling process by forming a magnetic circuit part and a terminal plate on a frame in a one body. CONSTITUTION: A magnetic circuit part(120) is combined with a frame(110) in order to generate a magnetic force. One side of a voice coil(131) is located inside the magnetic circuit part. The voice coil generates vibrations by interacting with the magnetic circuit part when power is applied. The outer circumference of a vibrating part(130) is supported by the frame. The inner circumference side of the vibrating part is combined with the other side of the voice coil. The vibrating part comprises a vibration plate(133) which generates an acoustic sound signal by being vibrated through the voice coil. A terminal plate is formed in the frame in a one body. A shielding member(115) prevents the interference of a sound wave in the center part of the vibration plate. |
