An entertainment sound panel that serves foreground music and paging applications.
The entertainment sound panel of the present invention is constructed of honeycomb
materials and adhesives. The driver of the entertainment sound panel is mounted
and supported on a bridge structure that spans the entertainment sound panel on
its back side. The driver interacts with the panel through the voice coil assembly.
The driver is separated from the entertainment sound panel by a contact pad to
deal with the shear problems between the sound panel and driver. Improvement in
low frequency (bass) response is provided by a butt joint that lays next to an
adjacent isolation pad, and can float freely. In another embodiment, the present
invention provides a lower cost flat panel sound radiator for low end business
applications where the performance characteristics of the radiator are less important
than the cost. The low end flat panel radiator is constructed from a polypropylene
or similar material. As with the entertainment sound panel, the driver of the polypropylene
sound panel is mounted and supported on a bridge structure that spans the sound
panel on its back side. Foam stabilizers positioned on either side of the driver
are used to set the height between the polypropylene sound panel and the bridge structure.
