PURPOSE: A dynamic receiver is provided to reduce deviation of product thickness by fixing a vibration plate as fitting a frame and a protector through insertion without bonding the vibration plate to an additional frame or the protector. CONSTITUTION: A yoke (110) forms a bottom side by being combined to a frame (100). A protector (130) covers the top of the frame by being combined to the frame. A magnet (200) is combined on the yoke. A plate is attached to the magnet and induces to form a magnetic path along the desired direction. A part of a lower part of a voice coil (300) is located in a magnetic circuit part comprising the yoke, the plate and the magnet, and the voice coil is vibrated up and down by the mutual electromagnetic force between the magnet and the yoke. The voice coil is attached to the bottom of a suspension (500), and is formed with an FPCB to apply a current to the voice coil. A vibration plate (400) is located on the upper part or the lower part of the suspension, and generates acoustic sound as vibrating by the vibration of the voice coil. |
