Bluetooth Speaker with Pi Zero and HiFiBerry

Introduction

Commercial Bluetooth speakers often compromise on audio quality. With a HiFiBerry DAC, you can build something much better.

The HiFiBerry DAC

The HiFiBerry DAC+ provides significantly better audio than the Pi's built-in audio output, with a proper line-level output.

Bluetooth Setup

BlueALSA allows the Pi to receive Bluetooth audio without PulseAudio, reducing complexity and latency.

Amplifier Selection

A Class D amplifier like the TPA3116 provides efficient, high-quality amplification for speakers up to 100W.

Enclosure Design

The enclosure affects sound quality significantly. We'll design a ported box for extended bass response.

Next Steps

Add battery power for portability, or implement multi-room audio with Snapcast.
