<p>The present invention discloses a vibrating system of flat-plate electrodynamic loudspeaker, which comprises a flat-plate vibrating plate and a voice coil mounted under the vibrating plate. The vibrating system is characterized in that the thickness of the vibrating plate within the voice coil is not more than 1/2 of that of the vibrating plate outside the voice coil. Alternatively, the vibrating plate within the voice coil can be replaced by a vibrating diaphragm. The thin plate within the voice coil according to the present invention can provide compensation for high frequency response, widen frequency band, and reduce the overall height of voice coil and vibrating plate. According to the present invention, a thin flat-plate loudspeaker that almost cover the full audio frequency bands can be designed, thereby producing a thin flat-plate full frequency speaker system to meet the demand of market.</p> |
