In this paper, we report a small speaker system that can output 110W and more from 9V- input without using any analog circuits such as D/A conversion and power amplifier. Using only digital processing, we can build a low power, full digital speaker using a digital direct driven speaker system (DDDSP) that can achieve high efficiency and low noise by increasing the number of speaker units. With this system, a high quality and low power consumption speaker system can be achieved at outdoor acoustic equipment, such as a concert hall and disaster. |
