Abstract
A speaker device including a transparent speaker and a light source module is provided. The transparent speaker is thin, soft, and has a low driving voltage. Light is emitted from a front side of the speaker panel, and transmitted in the same direction as the sound. Thus, the light is emitted along with the sound. The speaker device can be used as an indoor wall-painting or as a large advertisement poster for more visual effects to the viewer.
Claims55
A speaker device, comprising:
- a speaker panel combination module comprising:
- a diaphragm comprising an electret material having a conductive film formed on a surface of the diaphragm;
- and
- a fixed electrode plate having a plurality of openings and a plurality of spacers, the plurality of spacers are placed between the fixed electrode plate and the diaphragm for providing an operation area for the diaphragm to move and generate sound;
- and
- a light source module for providing light projected through at least a portion of the speaker panel combination modules.
A speaker device, comprising:
- a speaker panel combination module, comprising:
- a diaphragm comprising an electret material and a conductive film is formed on a surface of the diaphragm;
- and
- a fixed electrode plate having a plurality of openings and a plurality of spacers, wherein the plurality of spacers are between the fixed electrode plate and the diaphragm for providing an operation area for the diaphragm;
- and
- a planar light source module configured to provide light projected from at least a portion of the speaker panel combination module.
A speaker device with a transparent speaker panel combination module, wherein the transparent speaker panel combination module comprises:
- a diaphragm, made of an electret material, wherein a conductive film is formed on a surface of the diaphragm;
- and
- a fixed electrode plate, comprising a plurality of openings and a plurality of spacers, wherein the spacers are placed between the fixed electrode plate and the diaphragm so as to provide an operation area for the diaphragm to move and generate a sound, wherein
- light from outside the transparent speaker panel is incident through the transparent speaker panel on the transparent speaker panel combination module, so as to enable the transparent speaker panel combination module to make a sound and emit light in the same direction.
