A small Loudspeaker is a fun project to execute. You can link it with a USB port of 3.5mm to your iPhone or tablet and celebrate your private speaker. It can be attached to any 3.5 mm headphone output unit, such as Computer, music player and interactive media, etc. The LM386 IC enlarged the sound with a couple of external components.

Small Loudspeaker Circuit
Circuit Operation
I cut a male audio jack to 3.5 mm and soldered 2 wires, but one male audio jack to a breadboard should be 3.5 mm. And you can interact with a male end with a male Bluetooth version and a female audio jack with a computer.
Hence, this is very similar to my entire past “LM386 Audio Amplifier Circuit,” a 3.5 mm sound amplifier to replace the capacitor microphone. The potentiometer was also deleted because the computer Music player has enough reasonable control.
Applications and Uses
A small Loudspeaker is a fun project to do. You can sync this through an audio jack of 3.5 mm with your digital device and have a confidential loudspeaker. They can also be directly linked to a 3.5-mm audio output appliance, like a TV, a music player, smartphone, etc.
