Abstract

PURPOSE:To transfer the resonance frequency of the resonance mode, which is generated for multipoints driving due to plural coil bobbines, to the reproducing out- band frequency, by devising the form of the diaphragm. CONSTITUTION:Round diaphragm 11 of the dynamic loudspeaker which is driven at multiple points by plural coil bobbines is formed with ringlike projected string 12 provided on the outside circumferential part. As a result, the resonance frequency of the resonance mode which the diameter node generates is raised to the reproducing out-band frequency of the speaker to extend the reproducing band.
