Zusammenfassung:PURPOSE: A flat panel sound radiator system for use in suspended ceiling environments is provided to obtain high fidelity and to achieve superior fire performance. CONSTITUTION: A flat panel sound radiator assembly comprises a flat panel radiator(12) formed with a rectangular metal frame(13) that supports a sonic diaphragm(14). The legs of the frame are generally C-shaped in cross section and the diaphragm is mounted in the frame by means of a compliant foam surround(16). A metal bridge(17) is mounted at its ends to opposite legs of the frame and the bridge spans the radiator just above the back surface of the diaphragm. The bridge is configured with an electronics compartment that houses electronic components(18) of the system.
