Abstract

PURPOSE:To make satisfactory an electroacoustic conversion efficiency, raise a sound pressure level, and reduce a harmonic distortion, by making the upper surface of the center pole higher than the lower surface of two plates, and folding and placing a diaphragm. CONSTITUTION:The upper surface of the center pole 2 is made higher than the lower surface ot two plates 1. A diaphragm 3 is folded so that it passes through the upper surface of the center pole 2 from the lower surface of one plate 1 and reaches the lower surface of the other plate 2. According to such a constitution of the diaphragm 3, the voice coil 4 is distributed on the diagonal line of the magnetic air gap part, the area passing through its magnetic flux is increased, and also it is possible to utilize most of the strong and equal magnetic flux at the center in the magentic flux distribution going to the center pole from the plate 1.
