Abstract: A speaker support frame structure (10) and optional cover (49) for recessed mounting of a speaker (12) in a wall or the like. The frame structure (10) incorporates a one-piece, unitary molded frame body (15) which has an open central region (18), a flattened perimeter region (24) adjacent thereto, an adjacent peripheral upstanding shoulder region (26), and a terminal outwardly turned collar region (27). A speaker (12) is nestably received thereon. Leg members (37) are associated with screw means (36) that extend through orifice means (34) formed with the frame body (15). The leg member (37) pivotally outswing and engage wall surfaces with adjustable clamping force. The frame body (15) can be further provided with a frontal first ridge means (53) and also with a cover plate (54) which has rear second ridge means (55) so that the first (53) and second ridge means (55) can engage mutually in a connecting relationship.

Abstract: A signal distribution and communication arrangement (100) controls the broadcast of different types of signals through speakers located in various zones (A-D). The arrangement includes an audio receiver circuit (102) which responds to a music signal from an external music source, and an associated threshold detection circuit which provides a music mute function. Further, a page interface circuit, responds to a page signal generated from a telephone handset (126), which generates a paging control signal and serves as a power source to the telephone handset; and a doorbell interface circuit responds to any of a plurality of doorbell signal sources at differing locations (106, 107, 108) by generating a doorbell control signal and activating a corresponding doorbell tone sequence which identifies the location of the doorbell signal source. Finally, a control circuit, responds to these various circuits by selecting which of the corresponding signals should be broadcast by the speakers (L, R).
