Abstract:
An audio emitter comprises a support member operable to support a sound emittive material and a sound emittive material carried by the support member. A protective screen has a plurality of apertures formed therein, the protective screen being spaced a predetermined distance from the sound emittive material, said predetermined distance being a function of a resonant frequency of the audio emitter.
