Abstract

Patente de Invenção: <B>"ALTO-FALANTES"<D>. Uma unidade de acionamento de alto-falante de freq³ência média/alta compreendendo um elemento em forma de painel ressonante leve rígido, um alojamento no qual o elemento em forma de painel é montado, uma suspensão resiliente conectada entre as bordas do elemento em forma de painel e o alojamento, a disposição sendo tal que o alojamanto e o elemento em forma de painel juntos se definem um invólucro vedado, e um excitador de vibração eletrodinâmica para aplicar energia de onda de flexão no elemento em forma de painel para fazê-lo ressoar para produzir uma saída acústica, o excitador compreendendo uma montagem de ímã rigidamente fixado no alojamento e definindo um espaço anular e uma bobina de alto-falante disposta no espaço anular e rigidamente fixada no elemento em forma de painel perto do centro geométrico do mesmo, a localização da bobina de alto-falante no espaço anular sendo fornecido pela dita suspensão resiliente.Invention Patent: <B> "SPEAKERS" <D>. A medium / high frequency loudspeaker drive unit comprising a rigid light resonant panel-shaped element, a housing in which the panel-shaped element is mounted, a resilient suspension connected between the edges of the panel-shaped element and the housing, the arrangement being such that the housing and the panel-like element together define a sealed enclosure, and an electrodynamic vibration exciter to apply bending wave energy to the panel-like element to resonate to to produce an acoustic output, the exciter comprising a magnet assembly rigidly attached to the housing and defining an annular space and a speaker coil disposed in the annular space and rigidly attached to the panel-shaped element near the geometric center of it, the location of the loudspeaker coil in the annular space being provided by said resilient suspension.
