SPEAKER, DIAPHRAGM FOR SPEAKER AND SUSPENSION

摘要

The diaphragm of a high fidelity speaker is constituted of framework members, and a member filling between the framework members. The framework member is a flat plate, and all framework members are arranged radially outward from the center of the diaphragm in parallel with the vibrating direction and bonded to each other in the radial center and then bonded to a drive section. The framework member has high rigidity. The filling member is composed of a foamed body. The diaphragm has no skin and thereby has no resonance problem. Sound is radiated from the filling member. A suspension has rod-like members arranged in a line and bonded to the opposite ends of a first leaf spring, wherein second leaf springs are bonded to the opposite ends of the rod-like members at right angles thereto, and the ends of the second leaf springs are bonded to unmovable portions of the speaker. Intrinsic resonance occurring in the suspension is very small and displacement is small in directions other than the vibrating direction. An edgeless flat plate speaker system reproducing a sound with high fidelity with no impact of intrinsic resonance can be constituted using this invention.
