Abstract
A speaker device has a pair of speaker units each including a magnetic circuit. The magnetic circuits are opposed and connected to each other by a binding member. Vibrations generated by the speaker units are canceled to each other so that the occurrence of unnecessary vibrations can be suppressed and the transient characteristic can be improved. Acoustic load members are arranged in the front portions of frames so that the resonance frequency can be lowered and a band of reproducing sound of low frequency can be expanded.
