Abstract
Electro-acoustic device which when installed in continuous ceiling, partition or wall panels available in the market made of mineral fibre, plasterboard, multi-laminated wood, etc. converts them into flat, invisible radiators of high-fidelity sound by its special characteristic of being equalizable for each type of panel at the time of manufacture and assembly.
Claims8
An electro-acoustic device for installation on a continuous ceiling, partition or wall panel, comprising:
- (a) a chassis comprising a plurality of support bases;
- (b) a magnetic system disposed within said chassis comprising a moving coil;
- and
- (c) a coupler attached via an adhesive to said moving coil;
- wherein said chassis is adapted to adhere via an adhesive through said support bases to a rear face of the panel and to allow the resulting sound emitted by the panel to equalize, so that its frequency range between 40 and 18,000 Hz is within ±3 dB, by manipulating its dimensional and mechanical parameters and the nature of the materials of the device;
- and
- wherein said coupler is made from a material having properties similar to those of Kevlar® or titanium, comprises a hollow truncated cone having a flange on an end of said cone adapted to adhere to the rear face of the panel via an adhesive, transmits at great speed all the vibrations of the moving coil to the panel, and allows obtaining a linear response regardless of the nature of the panel, for which the material or geometric shape are changed and adapted to obtain said linear response.

An electro-acoustic device for installation on a continuous ceiling, partition or wall panel, comprising
- (a) a chassis comprising a plurality of support bases;
- (b) a magnetic system disposed within said chassis comprising a moving coil;
- (c) a coupler attached via an adhesive to said moving coil;
- and
- (d) a blanket of medium-density, self-adhesive foam disposed on said chassis;
- wherein said chassis is adapted to adhere through said support bases and said blanket to a rear face of the panel to eliminate audible resonance inherent in the panel and to allow the resulting sound emitted by the panel to equalize, so that its frequency range between 40 and 18,000 Hz is within ±3 dB, by manipulating its dimensional and mechanical parameters and the nature of the materials of the device;
- and
- wherein said coupler is made of soft plastic material, comprises a hollow cylinder having a flange on an end of said cylinder adapted to adhere to the rear face of the panel via an adhesive, and transmits at great speed all the vibrations of the moving coil to the panel and allows obtaining a linear response regardless of the nature of the panel, for which the material or geometric shape are changed and adapted to obtain said linear response.

- and
- wherein said coupler is made of a material having properties similar to those of cardboard, comprises a hollow truncated cone having concave walls and a flange on an end of said truncated cone adapted to adhere to the rear face of the panel via an adhesive, and transmits at great speed all the vibrations of the moving coil to the panel and allows obtaining a linear response regardless of the nature of the panel for which the material or geometric shape are changed and adapted to obtain said linear response.

- (b) a magnetic system disposed within said chassis comprising a moving coil;
- (c) a coupler attached via an adhesive to said moving coil;
- and
- (d) a support attached to a plurality of centering membranes at a centering membrane base comprising a plurality of adjustment screws for adjustment of the support in relation to the chassis to make possible a fine-centering of the moving coil in an air gap;
- wherein said chassis is adapted to adhere through said support bases to a rear face of the panel and to allow the resulting sound emitted by the panel to equalize so that its frequency range between 40 and 18,000 Hz is within ±3 dB, by manipulating its dimensional and mechanical parameters and the nature of the materials of the device;
- and
- wherein when centered in the magnetic system via the centering membranes, the moving coil transmits the vibrations to the panel by the coupler.
