VIBRATING SPEAKER

摘要

PURPOSE: A vibrating speaker is provided to add buffering to plate springs supporting a vibrating screen, to reduce the variation of a vibrating amount according to a frequency change, so that a stable vibrating characteristic can be outputted. And the vibrating speaker is provided to prevent collision between components completely, so as to improve endurance. CONSTITUTION: A housing(1) of which one side has a vibrating plate(2) for generating audio and the other side is shielded by a plate(3). A yoke(6) arranged in an internal center of the housing(1) is fixed in an internal circumference of the housing(1) by plate springs(4,5) mutually distant at predetermined intervals. A magnet(7) attached to an upper part of the yoke(6) to be branched to a north pole and a south pole in up and down directions configures a magnetic circuit. A voice coil(8) of which an upper end is fixed in the vibrating plate(2) is arranged to be near the magnet(7). A vibrating coil(7a) is attached on one side of the plate(3) to face with the magnet(7). And a damping unit(10) arranged in an internal circumference of the housing(1) reduces the variation of a vibrating amount by adding buffering to the plate springs(4,5).
