ABSTRACT:
A speaker enclosure is configured internally so as to minimize the generation of unwanted audio waves inside the enclosure, as well as to promote dissipation of those waves which are generated inside the enclosure. There is provided at the forward portion of the enclosure an isolation structure which converges in a rearward and inward direction and is located about the speaker diaphragm. There is further provided at a rear portion of the enclosure a structure for deflecting audio waves which are generated rearward from the speaker. The deflection structure reflects the audio waves against the sidewalls of the speaker, with the internal walls of the speaker being nonparallel so as to cause increased reflections of these audio waves and their eventual dissipation.
