High-frequency loudspeaker module for cinema screen

A high-frequency cinema loudspeaker module for deployment behind a perforated cinema screen is configured with a waveguide to compensate for the beam-spreading effects of the perforated screen at the high end of the frequency range and to facilitate and co-ordinate integration with a complementary midrange module of a total sound system in providing defined coverage in a theater. A compression driver is coupled to a waveguide that is specially shaped to narrow the horizontal beamwidth at the higher frequencies affected by the perforated screen, and thus provide compensation that results in a more uniform overall defined sound coverage in the theater within the designated high-frequency range. The module is configured with the driver and waveguide axes inclined downwardly at an angle of 6 degrees from horizontal to facilitate overall coverage.

Sound-damping laminate for loudspeaker structure

A sound-damping structure is provided for use as part of a sound-directing component of a loudspeaker. The structure includes a first structural layer, a second structural layer, and a core layer enclosed between the first and second structural layers. The first and second structural layers include a generally rigid material, and the core layer includes a sound-damping material. The first structural layer includes an outside surface facing an exterior of the sound-directing component. The second structural layer includes an inside surface having an interior of the sound-directing component through which sound energy is directed.
