Abstract
Un parlante en forma de panel comprende como mínimo dos paneles acústicos resonantes de modalidad de operación distribuida con un solo excitador provisto para excitar todos los paneles de manera que la energía de las ondas de flexión se transfiera de forma eficiente a cada uno de ellos para excitar la resonancia de modalidad distribuida en ellos y dar la salida acústica. Puede haber dos paneles, uno de mayor tamaño que el otro - presentando el de mayor tamaño una menor rigidez de las ondas de flexión que el de menor tamaño. El panel menor está posicionado excentricamente con respecto al panel mayor. Puede asociarse una pluralidad de paneles menores con un solo panel mayor. Una realización del invento proporciona un excitador montado en el o en cada panel menor, unido mediante adhesivo cara a cara con el panel mayor. Otra realización del invento proporciona el o cada panel menor formado dentro del panel mayor y unido a éste, con un excitador unido al o a cada panel menor. En la unión de los paneles se utiliza un material que forma un acoplamiento controlador elásticamente deformable. Una tercera realización del invento proporciona el o cada panel menor montado en un extremo de un acoplador asociado que pasa a través de y va unido al panel mayor, con un excitador unido al otro extremo del o de cada acoplador. En la unión del o de cada acoplador al panel mayor se utiliza un material que forma un acoplamiento controlador elásticamente deformable. El o cada acoplador es de sección tubular (Fig. 1).A panel-shaped speaker comprises at least two resonant acoustic panels of distributed operating mode with a single exciter provided to excite all panels so that the energy of the bending waves is efficiently transferred to each of them to excite the modality resonance distributed in them and give the acoustic output. There may be two panels, one larger than the other - the larger one having less flexural wave stiffness than the smaller one. The smaller panel is eccentrically positioned with respect to the larger panel. A plurality of smaller panels can be associated with a single larger panel. An embodiment of the invention provides an exciter mounted on or on each smaller panel, adhesive bonded face to face with the larger panel. Another embodiment of the invention provides the or each smaller panel formed within and attached to the larger panel, with an exciter attached to the or each smaller panel. A material is used to join the panels that forms an elastically deformable controlling coupling. A third embodiment of the invention provides the or each smaller panel mounted on one end of an associated coupler that passes through and is attached to the larger panel, with an exciter attached to the other end of the or each coupler. A material that forms an elastically deformable drive coupling is used in the attachment of the or each coupler to the larger panel. The or each coupler is of tubular section (Fig. 1).
