Abstract

PURPOSE:To improve transduction efficiency and directivity by forming a prolate voice coil and by making the whole body movable. CONSTITUTION:Voice coil 2 is made rectangular and the magnetic gap part of a magnetic circuit is made oblong; and voice coil 2 is arranged in the gap part and folded part 3 of voice coil 2 is made movable. Thus, the directivity in the prolate direction is improved. Further, by making voice coil 2 prolate, the directivity on the horizontal surface is improved.
