Abstract

Un altavoz que tiene un miembro de panel (1) y un excitador (3) fijado a la pieza de panel para excitar ondas de flexion en el altavoz para producir unasalida acustica. El miembro de panel tiene una variacion en la rigidez a la flexion por toda el área del panel para reducir los efectos, tales como laconcentracion de sonido emitido o la falta de uniformidad en la salida de potencia a la frecuencia de coincidencia.A loudspeaker having a panel member (1) and an exciter (3) fixed to the panel piece to excite bending waves in the loudspeaker to produce an acoustic output. The panel member has a variation in flexural stiffness throughout the area of the panel to reduce the effects, such as the concentration of emitted sound or the lack of uniformity in the power output at the coincidence frequency.
