Bluetooth Speaker Diagram
Thought for 13 sec
The LM386 is intended to drive a speaker with an impedance of 4 ohms or greater. In most applications, an 8‑ohm speaker is commonly used, which eases current demands and minimizes distortion.
Your project documentation also advises not to use a speaker under 4 ohms.
Would you like any additional details on load matching or performance considerations?

This diagram outlines the power and signal flow:
- The USB-C Port provides power for charging.
- The Charging Circuit manages the power conversion and charging of the Battery.
- The Battery supplies power through a Power Management Unit (PMU).
- The PMU feeds both the Bluetooth Module (for audio streaming) and the Audio Amplifier (LM386).
- The Bluetooth Module sends the audio signal to the amplifier, which then drives the Speaker.
Let me know if you need any modifications or further details!
