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.
