Abstract(in Japanese) (See Japanese page)
Abstract(in English) We proposed digitally direct driven speaker system (digital-SP), which reproduces sound with multi loudspeakers. A beam forming function can easily realized with the digital-SP by using several D-flip-flops, because the sub-loudspeakers are driven by 1-bit digital signals without DACs and amplifiers. In this paper, we sturdy a beam forming performance of a proposed loudspeaker whose vibration plate is excited by multi-voice coils.
