Abstract

A loudspeaker structure with a lighting effect includes a support frame having a magnetic circuit disposed at the bottom of the support frame, a voice coil installed above the magnetic circuit, a diaphragm adhered on the voice coil, and a suspending edge disposed between the diaphragm and the support frame, characterized in that the diaphragm is a thin object pervious to light, and a through hole is constructed separately at the front and rear ends of the magnetic circuit for receiving a light emitting device. After the loudspeaker is assembled, the light emitting device is installed in the interior space between the diaphragm and the magnetic circuit. Besides outputting sounds, the loudspeaker also produces a lighting effect, so as to make the manufacture and applications of the loudspeaker more diversified and allow the loudspeaker to have various changes.

Claims

1. A loudspeaker structure with a lighting effect, comprising:

a support frame, having a magnetic circuit at the bottom of said support frame;

a voice coil, disposed above said magnetic circuit;

a diaphragm, adhered onto said voice coil; and

a suspending edge, adhered between said diaphragm and said support frame;

characterized in that said diaphragm is a thin object pervious to light, and said magnetic circuit includes a through hole separately disposed at the front and rear ends of said magnetic circuit for installing a light emitting device, such that when said loudspeaker is assembled, said light emitting device is installed in an interior space between said diaphragm and said magnetic circuit, so as to output sounds as well as producing a lighting effect from the interior of said loudspeaker.

2. The loudspeaker structure with a lighting effect of claim 1, wherein said magnetic circuit comprises a U-shape circular iron member having a magnet therein and covered by an iron plate, and the diameters of said through holes are equal for passing said circular iron member, said magnet and said iron plate.

3. The loudspeaker structure with a lighting effect of claim 1, wherein said magnetic circuit comprises a U-shape circular iron member having a magnet disposed therein and covered by an iron plate, and said through hole is a stairway-like hole for passing said circular iron member, said magnet and said iron plate, and said iron plate is fixed at a position with a small diameter of said through hole.

4. The loudspeaker structure with a lighting effect of claim 1, wherein said light emitting device is a light emitting diode (LED).

5. The loudspeaker structure with a lighting effect of claim 1, wherein said diaphragm is made of a transparent plastic material and has a radial wavy pattern disposed on said diaphragm.
