Loudspeaker arrangement

Claim 2

A mounting for a loudspeaker in a drop ceiling or ''''false wall'''' structure of a type having panels or tiles, said mounting being supportable on beams suspended from a support structure or said panels or tiles, said mounting comprising, in combination, housing means including a substantially cylindrical housing having a side wall, a closed upper end, an open lower end, and a peripheral flange at said open lower end, said housing means being insertable through a conforming opening in a panel or tile, said peripheral flange being engageable with the exterior surface of the panel or tile around said conforming opening; a loudspeaker connector means secured to said housing means adjacent its closed upper end, mounting means securing said housing means to said structure with said flange sitting against the exterior surface of a panel or tile; a loudspeaker positioned within and protected by said housing means, and having electrical leads extending to said connector means, said loudspeaker having a peripheral rim, an annular cross section ring having an outer diameter substantially equal to the inner diameter of the side wall of said housing, means securing the rim of said loudspeaker to a horizontal leg of said annular cross section ring, the vertical leg of said annular cross section ring having apertures alignable with apertures in the side wall of said housing, and resilent clip-type rivets insertable, from the exterior of said housing, through the aligned openings in the side wall of said housing and in the vertical leg of said ring to mount said ring and said loudspeaker within said housing.

Claim 3

A mounting for a loudspeaker, as claimed in claim 1, including a speaker grill having a flange secured to the horizontal leg of said annular cross-section ring in engagement with the lower surface of said horizontal leg.

Claim 4

The mounting for a loudspeaker, as claimed in claim 1, including a plaster ring having a central circular opening therethrough; support means supporting said plaster ring on said suspended beams with said plaster ring positioned in spaced relation beyond a panel or tile having a conforming opening for receiving said housing with a circular aperture in said plaster panel being aligned with the opening in said panel or tile; said mounting means securing said housing to said plaster panel.

Claim 5

A mounting for a loudspeaker, as claimed in claim 3, in which said supporting means comprises a pair of laterally spaced straps each extending between and secured to a pair of adjacent suspended beams; said plaster ring being substantially rectangular in plan and having, along a pair of opposite edges, struck-out tongues engageable in gripping relation beneath a strap when said plaster ring is supported on said straps; said plaster ring being formed, along each of said opposite edges, with a central rectangular recess therein, and said circular aperture being offset at a pair of diametrically opposite points to form shallow rectangular rEcesses each aligned with one of said first mentioned rectangular recesses; said mounting means including a pair of resilient clips each seated in a respective one of said first-mentioned rectangular recesses and gripping said plaster ring inwardly thereof, each clip including an upwardly and inwardly sloping leg having a curved upper edge formed with a rectangular slot which is substantially aligned with the associated one of said shallow rectangular recesses when the respective clip is mounted on said plaster board; said housing having a pair of bushings extending from its side wall in diametrically opposed relation adjacent the lower end of said housing; and a pair of torsion springs each wound around a respective bushing and having a pair of diverging legs extending upwardly from the associated bushing and having outturned ends forming hooks; said housing being mounted on said plaster ring by compressing the legs of the two torsion springs to insert the hooked ends thereof through the slots in the clips, followed by pushing the housing through the aperture in said plaster ring until the housing flange engages the surface of said panel having such conforming opening; said housing being retained in position by the friction of the diverging legs of said torsion springs against the end edges of the associated slots of said clips; said housing being movable relative to said structure, for inspection maintenance and repair of a loudspeaker mounted in said housing, by pulling on said flange, with the hooked outer ends of the legs of said torsion spring limiting such movement by engaging the curved upper ends of the legs of said clips.

Claim 6

A mounting for a loudspeaker, as claimed in claim 4, in which each strap includes an upturned leg at each end thereof formed with a series of apertures whereby the associated strap may be secured in adjusted relation to said suspended beams.

Claim 7

A mounting for a loudspeaker, as claimed in claim 1, in which said loudspeaker connector means comprises a BX connector mounted through said housing adjacent said closed upper end thereof and arranged to have a BX cable connected thereto for connection of said loudspeaker to a public address system and the like.

Claim 8

A mounting for a loudspeaker, as claimed in claim 1, including an annular gasket interposed between said loudspeaker rim and said horizontal leg of said annular cross section ring; and threaded connector means extending through aligned apertures in said rim and in the horizontal leg of said annular cross section ring and securing said rim to said annular cross section ring.

Claim 9

A mounting for a loudspeaker, as claimed in claim 7, in which said housing is formed with plural inwardly directed abutments in its side wall at uniform distances above said rivet receiving apertures in said side wall; said abutments engaging the upper edge of said annular cross-section ring to limit upward movement of said annular cross-section ring in said housing to a predetermined distance above the open lower end of said housing.

Claim 10

A mounting for a loudspeaker, as claimed in claim 1, including a driver assembly secured to said speaker within said housing and enclosed thereby; and a speaker transformer mounted on said closed upper end of said housing and disposed within and enclosed by said housing, said transformer being electrically connected to said driver assembly.

Claim 11

A mounting for a loudspeaker, as claimed in claim 9, including a speaker impedance selector switch mounted within said housing adjacent said closed upper end thereof and connected to said loudspeaker, said selector switch being adjustable from the exterior of said housing.
