Spherical diaphragm for loudspeaker - is mounted for driving by central, hollow sphere of light but rigid material

摘要

A hollow sphere of light rigid material is fixedly mounted in the middle point of the loudspeaker diaphragm. thus, on one hand, radiation is produced all around the loudspeaker. On the other hand, the radiating surface of the loudspeaker is increased. This produces a more natural and clearer loud speaker output. ADVANTAGE - More compact construction. Provides improved properties in smaller space. Allows increased loading.
