Abstract

The present invention concerns an open cabin electroacoustic transformer, called bipolar loundspeaker, where the sound reproduction units are attached to the front surface of this cabin (baffle) which operates as a separator between the front and the backwards radiation of low frequency waves of the reproduction units. Due to the construction of the front baffle by the suitable combination of two materials, the problems of the state-of-the-art bipolar loudspeakers are overcome; in particular the parasite eigenvalues of the front baffle are significantly reduced, more complete separation of the front and the rear low frequency radiation is achieved with a low production cost, with the ability to install conventional loudspeakers, with a reasonably small front baffle surface and the additional advantage of aesthetic downsizing, and they permit the listener to view the space behind the loundspeaker.
