Definitions

  • a bowed thin springy sheet metal diaphragm is formed with projecting clips, projecting from the rearwardly bowed, that is, convexly bowed surface to be engaged by the loudspeaker, and with hook-like projections, projecting from the concavely bowed surface, to permit slipping one hook into the edge of the sound opening of the sound board, hooking the speaker into the clip, and then flattening the bowed diaphragm against spring pressure until the second hook engages around another side of the sound opening, of the sound board, the loudspeaker being then snapped in holding position on the diaphragm strip by another clip; the first clip can be replaced by deform
  • the present invention relates to a loudspeaker attachment fitting to attach loudspeakers to sound boards, and more particularly to permit attachment of loudspeakers in positions where accessibility is severely limited, such as, for example, in the dashboard assembly of automobiles.
  • a strip or sheet, or diaphragm of springy material, which is bowed, is formed with projecting hooks adapted to engage over the edge of the rim of the sound opening in the sound board.
  • a snap-connection to the loudspeaker is formed, for example by a pair of spring clips, or by one spring clip and deformable attachment flaps or the like.
  • the loudspeaker may be preliminarily secured to the strip, for example by one clip, or the attachment flaps.
  • the bowed diaphragm, or strip is then inserted, from behind, such that the hooks will overlap the edge of the sound board opening (for example an opening, or punched holes in the dashboard or similar structure of an automobile), and the loudspeaker is then pressed towards the sound board, thus flattening the bowed strip to provide for secure engagement of the hooks over the edge of the sound board, and snapping the loudspeaker into the remaining spring clip.
  • the sound board opening for example an opening, or punched holes in the dashboard or similar structure of an automobile
  • FIG. 1 is a side view of the loudspeaker attachment fittings
  • FIG. 2 is a front view of the loudspeaker attachment fittings, taken from the side of the speaker;
  • FIG. 3 is a combination view illustrating the fitting and a loudspeaker before assembly
  • FIG. 4 is a view of the loudspeaker with the fitting assembled to the sound board
  • FIG. 5 is a side view of a further embodiment
  • FIG. 6 is a top view of a further embodiment.
  • FIG. 7 is a rear view of the loudspeaker attached to a sound board.
  • FIGS. 1 and 2 illustrate a sheet or diaphragm 2 having a sound opening 1 formed therein.
  • the diaphragm is curved, so as to have a convex surface at the upper side of FIG. 1, and a concave surface at the lower side of FIG. 1.
  • Projections are formed on the diaphragm 2, for example by being punched from the diaphragm material.
  • the projections are located at sides of the loudspeaker roughly parallel to the axis of bowing, or bend of the spring material. These projections are in form of clips 3, projecting form the convex side, and hooks 4,
  • the clips 3 are generally S-shaped and are so dimensioned with respect to the loudspeaker that when the diaphragm is stressed against its bend, that is, is flattened, the clips 3 will snap over the edge of the cage of the loudspeaker to be held.
  • the hooks 4 are generally U-shaped and dimensioned to fit around the edge of the sound opening 1 of the sound board 2. They project outwardly, that is, in the direction opposite to the clips 3.
  • the diaphragm is further formed with projections 5 which are dimensioned and placed on the diaphragm to fit into remaining attachment holes usually present in loudspeaker cages, and to properly locate the loudspeaker cage on the diaphragm.
  • a loudspeaker 6 is secured to the sound board 7, for example, by first loosely inserting the diaphragm 2 in the sound board opening as illustrated in FIG. 3. This can be done, for example, by hand or by loosely attaching the loudspeaker 6 to one of the clips 3.
  • the hooks 4 extend around the edges 9 of the sound board opening 8.
  • the edge 11 of the loudspeaker cage usually having a ring of compressible'material 10 such as foamed plastic or the like placed thereon, causes stressing of the bowed strip or diaphragm 2.
  • the hooks 4 will slip behind the edges 9 of the opening 8 in the sound board, and clips 3 will snap around the edge 11 of the loudspeaker cage.
  • the loudspeaker cage is thus securely held against the sound board 7.
  • the diaphragm can be formed of an essentially rectangular sheet element (wherein rectangular is deemed to include the special case where all sides are equal, that is, square), may be round, or have any other suitable shape fitting the loudspeaker.
  • the sound opening 1 of the diaphragm 2 need not be an entire opening but can be in the form of a grille, punched grid, or the like; likewise, the sound opening 8 in sound board 7 may already have the form of a grille, provided only that openings of sufficient size are formed near the edge 9 to permit the books 4 to slip thereover. Such partial openings are to be deemed to be within the scope of the term sound opening" herein referred to.
  • the modification according to FIGS. 5-7 is particularly suitable where mounting space is limited or highly impeded.
  • the diaphragm 12 is essentially similar to the diaphragm 2, but differs in that one side is not fonned with a clip 3 but rather is formed with flaps 13 which are located to fit through the lateral attachment holes 14 of the loudspeaker cage of loudspeaker 15.
  • the loudspeaker 15 is pre-assembled with the diaphragm 12 by threading flaps 13 through two matching attachment holes 14 of the loudspeaker 15, and then deforming the flaps to securely hold the diaphragm and the loudspeaker together.
  • the pre-assembled sub-assembly of loudspeaker-diaphragm is then placed in position, for example behind or beneath the dashboard of an automobile, permitting installation with one hand only, by slipping hooks 4 around the edge 9 of the sound board, as before, and snapping the left side of the loudspeaker (with reference to FIGS. 5-7) into the spring clip 3, so that the loudspeaker will be held in position as seen in FIG. 7.
  • the sound zone that is, the region from where the sound is projected covers the sound hole, or opening, and as referred to above, may be partially obstructed
  • the diaphragm can be made as a flat sheet with a sound opening as shown in FIGS. 2, 6, or as a strip, with suitable perforations, or suitably shaped to permit attachment of the loudspeaker thereto through one or more of its attachment holes, or by spring clips.
  • the arrangement in accordance with the present invention permits mounting of a loudspeaker in locations which are accessible only with great difficulty.
  • the attachment requires no additional screws, rivets, or any auxiliaries which require the use of tools, and can be entirely carried out by hand and without any tools whatsoever. It does not require any drilling or modification of the usually existing sound openings in the sound board.
  • unstressed state is bowed, and when stressed and flattened has an outline extending at least in part to the outline of the cage of the loudspeaker, the sheet having a sound opening zone similar to the sound opening of the sound board;
  • means securing said sheet (2) to two opposed lateral sides of the loudspeaker (6) including at least one outer spring clip (3) projecting away from the convex surface of the bowed sheet and at the side of the sheet which extends parallel to the bend axis of the bowed sheet;
  • said sheet (2) to the sound board (7) including at least one inner hook (4) projecting away from the concave surface of the bowed sheet at the sound opening zone and located nearest to said side of the sheet which extends parallel to the bend axis of the bowed sheet, the hook (4) being bent over said sheet and away from said sound zone to permit fitting of the bowed sheet, with the concave surface against the sound board (7 and engagement of the hook through the sound opening (8) of the sound board (7) and over the edge (9) thereof and upon stretching and flattening of the sheet by contact of the convex surface with the loudspeaker cage, engagement of the edge of the cage of the loudspeaker with the clip (3).
  • a fitting according to claim 5, wherein the gripping means (13) comprises deformable projecting flaps.
  • the clip has a first spring portion extending from the side of the sheet towards the sound zone thereof, and a second end portion reversely bent with respect to the spring portion to permit snap catch engagement of the loudspeaker cage with the clip.
  • a loudspeaker having a speaker cage being formed with an edge rim and an attachment fitting to attach the loudspeaker to a sound board having a sound opening comprising the combination of a stressed, substantially flat strip of spring material which, when unstressed, is convexly bowed towards the speaker cage, said flat strip lying flat against the speaker cage;
  • a resilient spring clip projecting from the surface facing the loudspeaker on said strip to resiliently engage over the edge of the speaker cage at the other side thereof, said means and spring clip being located at opposite sides of the axis about which the strip bows when unstressed;
  • hooks projecting from the surface which is concavely bowed when the spring is unstressed, the hooks having end portions facing away from said axis and engaging around the edge of the sound opening of the sound board.
