Abstract:

A loudspeaker including a generally spherical cabinet and at least one speaker driver contained in the cabinet and dividing the cabinet into a major sound chamber and a minor sound chamber. The cabinet has at least two sound propagation ports communicating with the major sound chamber and at least two sound propagation ports communicating with the minor sound chamber. The spherical cabinet of the loudspeaker provides an omni-directional radiation pattern. According to one possible embodiment, the at least one speaker driver comprises two speaker drivers facing each other and connected out of electronic phase so as to operate as a single push-pull unit. The loudspeaker, therefore, utilizes the rear sound waves created by its speaker drivers. One of the speaker drivers is substantially contained in the minor sound chamber and the other of the speaker drivers is substantially contained in the major sound chamber. According to another possible embodiment, the loudspeaker further includes at least one support assembly extending through the cabinet and linking opposing hanging points on the outside of the cabinet.
