MP3 Player Circuit Diagram Since the mp3 player module accepts only 3.3 V or 5V so we have used voltage regulator here to regulate the battery’s 9 V to 3.3 V. A switch to on/off is present too on or off the module.0.1 uF capacitor is used here for noise filtration and is connected across Vcc and GND.

This circuit saving on battery current, which is quite low with middle volume, rising to 25 -30mA as a volume is increased. This gives us a 250 mW amplifier, enough to drive a loudspeaker to the same volume as a mobile phone or MP3 player. The input must be about 100-500 mV to drive amplifier fully.

Connect the circuit diagram as in the one marked with “Amplifier with Gain = 20” and you get 20-fold the signal. If you need exactly 6, you can play a round with the resistance on the input. For splitting the signal, you can use resistors for basic splitting. Google “signal splitter circuit” to see some examples.

Amplifier Circuits Introduction to Impedance and Bandwidth Control. Modified Response Curves Previous modules have concentrated on producing a flat frequency response over the required audio frequency range. It is sometimes necessary however, to modify the flat response of an audio amplifier by making particular stages of the amplifier frequency

Therefore I designed this amplifier which uses two LM3886 per channel, in parallel circuit. This amp can deliver about 50W into a 8-ohm speaker and 100W into a 4-ohm speaker. This is a stereo amplifier and therefore 4 LM3886s are used. The LM3886 circuit is in a non-inverted configuration, so the input impedance is determined by the input ...
