hi there, I am currently using a PIC to generate tones on the speaker. It runs on 5Volts. The speaker produce a tone which is too soft to hear after 5 meters away. Is it possible to increase the volume of the speaker using a 5Volts setup? Thanks, John Chung __________________________________ Yahoo!
