US 2006/0233402 A1 · Electroacoustic transducer

Abstract

One mode of the present invention provides an electroacoustic transducer composed of a multifaced diaphragm assembly and a multifaced speaker housing assembly that is housed inside the multifaced diaphragm assembly. The multifaced speaker housing is configured by combining the outer peripheral surface of a plurality of individual speaker drive units into a nearly spherical shell. The multifaced diaphragm assembly, which has thereinside the multifaced speaker housing assembly, is configured to have a plurality of regular pentagonal diaphragm segments that are combined together into a nearly spherical shape shell, and a plurality of speaker drive units opposing the diaphragm segments from inside in one-to-one relation. Each speaker drive unit has a bobbin, the one end portion of which is adhered to the center portion of the inner surface of each diaphragm segment.
