How to make a do-it-yourself speaker for a phone






Let's get started!

1. Make markings on the box and cut a hole for the speaker.








2. Solder the wires to the speaker and glue it to the box.









3. We take the mosfet and solder as shown in the photo. Solder the resistor, capacitor, speaker, connector for the crown.














4. Cut out the hole for the switch and insert the switch. Solder the switch and wire with aux connector. Gently glue all the insides in the box. Putting the box together and done!



























Advice:
