Abstract
Improvements in the acoustic circuits of electrophonic transducers, essentially characterized by the fact that said circuit is constituted by two enclosures or acoustic cavities whose own resonance frequencies comprise respective orders of the acoustic spectrum corresponding to their high and low levels respectively, whose cavities are associated in transmission rate, on the one hand in common with the movable organ of the electroacoustic transducer device, and on the other, independently, with respective outputs, the relative responses of both cavities being adjusted so that, at the environmental outlet, an reinforcement of the low frequencies orders, without attenuation of the high ones.
