2 Sheet' s-Sheet- 1 Patented Jan. 7, 1975 2 Sheets-Sheet 2 1 LOUDSPEAKER AND ATTACHMENT FITTING 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.
It is usually customary to secure a loudspeaker on a sound board by means of screws. This leads to difficulties if the sound board is so shaped or located with respect to other structures that accessibility of both sides to the sound board is limited, as is frequently the case when loudspeakers are to be installed in automobile radios. Securing loudspeakers, therefore, is often difficult and in any event is time-consuming It is an object of the present invention to provide a loudspeaker and more particularly a loudspeaker attachment fitting construction which permits rapid installation of loudspeakers in locations where accessibility is impaired.
SUBJECT MATTER OF THE PRESENT INVENTION Briefly, 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. At the convex side of the bowed sheet or strip, or diaphragm, 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 invention will be described by way of example with reference to the accompanying drawings, wherein:
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; and
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,
projecting from the concave side. 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.
Referring now to FIGS. 3 and 4, which illustrate the use of the fitting of the present invention: 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. As the speaker 6 is then pressed towards the sound board 7, 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,
for example by being formed with grillwork or the like.
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.
Various changes and modifications may be made within the scope of the invention concept.
