  • Patent number: 7447322
    Abstract: A speaker having a transparent sound panel and an exciter connected to the transparent sound panel for converting electrical energy received by the exciter, into vibrations that are transmitted to the transparent sound panel, resulting in the transparent sound panel transmitting sound. The speaker also contains a stiff panel located between the exciter and the transparent sound panel, where the stiff panel minimizes dampening qualities associated with material utilized to fabricate the transparent sound panel and minimizes bending of the portion of the transparent sound panel that is in contact with the stiff panel. In addition, a dampening pad is located within the exciter for absorbing a portion of excessive mid-high frequency vibrations emanating from the exciter prior to transmission to the transparent sound panel.
