Abstract

A mounting system for loudspeakers composed of a multiple frame which retain 2 or 4 loudspeakers and a set of single frames which host one loudspeaker such that loudspeakers of standard manufacturing size and type can be mounted to the ceiling or walls of a listening space.

Description

The invention relates to stands for mounting loudspeakers. and particularly for mounting loudspeakers on the ceiling or walls of the listening area. Where the term stand refer to the type of product, consisting of supports designed to host loudspeakers at a different height from the floor level.
Loudspeakers are normally mounted at the periphery of a listening area to direct sound output from the speakers towards a central point; this type of speaker arrangement is referred to hereinafter as a 'convergent' configuration. Though such speaker arrangements result in a high quality and balance of sound in the central region of the listening area, the sound quality, intensity and balance in the outer regions of the listening area are generally of a lower standard. It could be argued that the loudspeakers should be placed in other points and mounted the ceiling or walls of the listening area; this can result in improved sound properties given that other dispositions can be achieved ; among which placing the speaker so to direct sound in a divergent configuration. However, to date, sound systems suitable for ceiling mounting of loudspeakers have not been widely available.
Furthermore , placing the loudspeakers on floor , forniture but also traditional stands results in effects such as floor and walls vibrations and reverberance , effects these that impact the quality of sounds as well as result detrimental to non listeners because of the wall and floor vibrations. These effects can be sensibly reduced if the loudspeakers ar suspended to walls or ceiling rather than adapted to surfaces.
The present invention provides a multiple ceiling mounting stand for mounting a plurality of loudspeakers. The stand comprising a plurality of housings mounted on a central frame, each housing receiving and securely retaining a loudspeaker, whereby the speakers are mounted in a divergent or radial configuration.
The present invention provide as well single ceiling mounting stands for set of speakers to be mounted individually at different point of the listening area to walls or to the ceiling.
The invention provides simple and inexpensive apparatus capable of mounting speakers from an existing sound system to walls or to the ceiling.
The multiple frame (fig. 3) comprises upper rectangular structure 6. The confronting faces -of the structures 6 have two tapped mounting holes 8 provided on the longer pair of sides adjacent each corner to receive cylindrical threaded rods or pipes 10. The rods 10 project perpendicularly to the plane of the structures 6 to define therewith a generally cubical frame. A pair of cylindrical tube 11's are mounted on each of the rods 10 for pivotal movement about a vertical axis. Supporting arms 4a,4b project from each tube to meet pivots openings 12a and 12b's. The tubes are similarly firmed together pairwise by 4 rectangular bar (13) at the opposite ends in correspondence of each of the 4 corners. The frame may be attached to the ceiling of a listening area by any appropriate support or bracket.
Each housing (fig 5) has two component parts. Two similar trays - have bottom reinforcement struts 21. The free ends 20 receive the free ends 22 of the upper portion in a sliding-fit engagement to form lower and upper support surfaces of the housing. By adjusting the position of the two housing portions 23a and 23b the height can be adjusted. The speaker is firmed between bottom supports 21's of both the components 23,a and 23b and front tubular frame 25. This housing leaves the front of the speaker free from any parts crossing its outward face. Clamping 45, screws or other releasable fastening elements are provided to secure the housing portions. Further the housings may be mounted on the frame(s) for rotation. (fig 4) where the housings may be releasably fastened on the frame at preselected angle to the vertical's by means of ends 24a, 24b.
The multiple mounting stand is secured to the centre of the ceiling of the listening area. (fig.1)
Single mounting stands (fig.6) are formed by 1 longitudinal bar (17) from which departs a string or chain (18) that receive the cylindrical rods (10) and cylindrical tubules (11) and lateral supports 4's whose shape will differ from lateral arms of the main mounting stand to the extent that the former will be shorter in width where pivot openings 12a, 12b's are positioned immediately next to cylindrical tubes (11) such that the line formed by the pivot openings 12a, the top opening 12b and the longitudinal (horizontal) bar will be perpendicular to the ceiling plane ( see fig.6). Similarly 2 bolts (19) firm each of the cylindrical tubes (11) from the bottom. The speaker housing is adapted in the same fashion to the lateral arms 4's as for the main mounting stand. This single mounting stand hosts a single speaker.
The single mounting stand is suspended to the ceiling or walls at specific points.(fig 1)
In order to interpret the text, the following is a detailed description of the invention with reference to the accompanying drawings in which: Figure 1 is an illustrative view of a ceiling stand system according to the description consisting of a system of 6 speakers arranged in a divergent (radial) configuration; Figure 2 is an illustrative view of the multiple stand shown in Figure 1 with a single housing mounted to the central frame; Figure 3 is an illustrative view of the multiple frame ; Figure 4 is an illustrative view of the housing shown in Figure 2; Figures 5 shows front and side views of the components of the housing; and Figures 6 is an illustrative view of the single mounting speaker stand.
To begin assembling of the various components of the ceiling mounting stand, a loudspeaker 50 is placed in element 23a of housing (fig 4) with its front side adjacent the outer edge , element 23b is mounted and the housing height adjusted according to the size of the speaker. The housing and the speaker are mounted to the multiple frame or to the single frame ; end (24a) is fitted in opening 12a) of lateral arms 4a , the vertical angle adjusted to position, in order to facilitate this process the upper lateral arm 4b is disjoint from the lower 4a. End (24b) fitted in any opening 12 b); clamping screws (46) are tightened. The housing components is in position and thus secures the loudspeaker within the housing. The other three loudspeakers are mounted to the frame in similar fashion. Additionally other speakers on single mounting stands (fig 6) are mounted in the same fashion at specific points (fig.1). The multiple and the single frames may be permanently or releasably mounted to the ceiling or walls of the listening area by any appropriate means.
Of course modification of the preferred embodiment are possible without departing form the spirit of the invention. For instance the frame could be adapted to receive any size of loudspeakers , or the multiple frame could be echtagonal to support six speakers. the various components may be manufactured form metal , aluminum , plastic or other suitable material.
