Abstract
A multiple cone type loudspeaker having a construction including a plurality of vibrating plates and a plurality of baffle plates protruded forwards from an enclosure of the loudspeaker. Each of the baffle plates serves to effectively isolate both spaces respectively defined at front and back sides of each corresponding one of the vibrating plates protruded forwards beyond the front surface of the enclosure. As a result, there is no phenomenon that the density of air is equalized in both spaces respectively defined at front and back sides of each vibrating plate as the vibration of the vibrating plate is continued. Accordingly, it is possible to achieve an extension in regeneration band, an improvement in directivity and a generation of dynamic sound.
