  • Ultra-slim speaker unit capable of improving low-pitched sound characteristic and sound pressure and board equipped with the same
    Patent number: 8879778
    Abstract: A speaker used as a household appliance is provided. The speaker has an ultra-slim structure suitable for an ultra-slim TV and is applied to a woofer speaker representing a superior low-pitched sound characteristic. The speaker has the ultra-slim structure and improves the low-pitched sound characteristic and sound pressure by increasing the amplitude. Outer appearances of a damper and a frame are changed to enlarge a diameter of a voice coil in comparison with an outer diameter of the speaker, the damper has a two-step structure such that a longitudinal amplitude of an upper side of the damper is increased to improve the low-pitched sound characteristic in a state in which a lower side of the damper is put on the frame, and a size of a vibration plate is enlarged to improve the low-pitched sound characteristic and sound pressure. A flat plate is used as the vibration plate.
