If you need a bit of power for your small speakers, this well made micro audio amp amplifier module will do. The LM386 Audio Amplifier Module is a basic signal amplifier with 200X Gain, designed to accept incoming audio signals and boost them while maintaining the correct sound levels and ratios. Audio Power Amplifier is a low-voltage Electronic Module with a small form factor that can read incoming signals from audio devices like radios, guitar pickups, and microphones to amplify them for audio output devices like speakers, headphones, or additional digital modules. Subwoofer Amplifier features an internal gain of 20x to keep the external parts count as low as possible, and an onboard potentiometer for manual on-the-fly volume adjustments. You can definitely use this High gain Audio Amplifier Module for other musical projects too. electronicstore.pk Amplifier Amplitude Module Board with Adjustable Resistance Control Potentiometer for Arduino Raspberry Pi:
