  • Speaker having a laser vibration diaphragm
    Patent number: 6804371
    Abstract: A speaker includes a housing having a diffusion opening provided with a laser vibration diaphragm. The laser vibration diaphragm has reflective spatial patterns, so that the speaker may present multiple-image variations under different rays of light, thereby enhancing a viewing effect and aesthetic quality of the speaker. Thus, the laser vibration diaphragm may produce spatial variations by the difference of incident angles of the light, thereby obtaining a viewable strong sensation to the people, and thereby enhancing the viewing effect and aesthetic quality of the speaker.
    Type: Grant
