Abstract: Disclosed herein is a light-emitting speaker comprising mainly a loudspeaker and a speaker cabinet in which the loudspeaker is mounted. The loudspeaker itself comprises a chassis, a diaphragm, a voice coil, a magnet, some accessories and decorative material. One or more LEDs are mounted on the cabinet to provide light emitting effect. The said LEDs may be also mounted on any location at the loudspeaker, the inner or outer wall of the cabinet. On the loudspeaker or the cabinet fasterers may be placed to mount the said LEDS. Furthermore, the LEDs can be controlled by either a voice or an electronic controller, or connected to the speaker's audio control circuit to vary the intensity of the light by the sound generated by the loudspeaker. The speaker with LEDs according to the present invention is designed so that the speaker can convert audio signal into sound, and to provide lighting effect while the speaker is functioning.

Abstract: The present invention provides a loudspeaker having double symmetric magnet-circuits, double voice coils and double dampers. The loudspeaker comprises a diaphragm holder, a diaphragm, an upper and a lower dampers, an annular steel magnet, a core, voice coils, an upper and a lower plate. Wherein the core is a steel magnet, the polarities of its upper and lower ends being opposite to those of the upper and lower ends of the annular steel magnet, so are two symmetric and parallel magnet-circuits formed. Thus the intensity of the magnet field in the two magnet gaps became very high because of the two magnet sources, so is the high power loudspeaker able to work normally.
