PURPOSE: A speaker for an output improvement is provided to increase an output in comparison with an existing speaker. CONSTITUTION: A speaker includes a case(31), a vibration plate(24), a yoke(32), a magnet(11), and a voice coil(21). The case brings a wire which is connected with a sound system in. The vibration plate is mounted on the case. The yoke is mounted on a position which is not a part corresponding to the right center of the vibration plate among the flank sides of the case. The magnet is mounted on the yoke and forms a magnetic field. The voice coil is mounted around the magnet and vibrates the vibration plate by an interaction between the magnet and an electric signal which is applied from the wire. |
