DIAPHRAGM FOR SPEAKER, SPEAKER USING THE DIAPHRAGM FOR SPEAKER, AND ELECTRONIC EQUIPMENT USING THE SPEAKER

摘要

PROBLEM TO BE SOLVED: To provide a diaphragm for a speaker applied to electronic equipment such as various acoustic apparatuses that realizes stabilization of the frequency characteristic. SOLUTION: The diaphragm for speaker is provided with at least two kinds of areas 27a, 27b with different internal losses. Through the configuration above, the spurious resonance of the diaphragm is reduced to realize the stable frequency characteristic while maintaining the physical property of the whole speaker use diaphragm 27.
