| Abstract(in English) | Only piezoelectric type digital loudspeaker can be achieved as 16 bits. But its radiated sound power is low. Because of increasing radiated sound power, in this paper, the possibility of multi-bits and broad-band of electrodynamic type digital loudspeaker is experimentally coil type loudspeakers is effective or not. From the results, it can be said as follows : (a) The possibility of 12 bits digital loudspeaker of multiple driving type is obtained with the addition of driving power on the vibrating plate. (b) Frequency response of multiple driving type plane loudspeaker is flat in frequency range of 400Hz to 12kHz. (c) The spiral coil type plane speaker is realizable. |
