I'm not into the analogue business. I only deal with digital circuits. I have a circuit ready consisting of a voice chip and a speaker (about the previous threads i posted, the circuit worked suddenly all by itself with the 25ohm). The sound is Okay, but it's too low, and i want to increase the volume. The output from the voice chip is 50mW. What can i do to increase the volume, and what hardware do i need? I dont know anything about amplifiers, and i never dealt with sound before, so don't blame me if this question sounds stupid.
