Abstract

PURPOSE:To make it possible to obtain a desired frequency characteristic and a tone quality with a simple operation at an assembling time and a use time by linking two volume rooms, at least, formed in back of a diaphragm by an inertance tube having a prescribed vibration-system equivalent mass. CONSTITUTION:Voice coil 8 is arranged in gap 7 between yoke 4 and center pole 5 of magnetic circuit 2, and voice coil 8 is connected to diaphragm 9. The first volume room 21 and the second volume room 22 are formed in back of diaphragm 9. These volume rooms 21 and 22 are linked with each other by inertance tube 25 having a prescribed vibration-system equivalent mass, namely, an equivalent mass for obtaining a desired low-band resonance frequency. Two holes 31 and 32 are formed in prescribed positions in inertance tube 25 and are opened for volume room 22. By this constitution, at an assembling time and a use time, a desired frequency characteristic and a desired tone quality can be obtained by removing a grip to expose inertance tube 25 and opening and closing holes 31 and 32 selectively.
