Sound Bite Boom Box

Project Overview

A compact 4-inch mono boom box designed to run on standard drill batteries, delivering portable, high-output sound in a durable, modular housing.

Built as a self-contained audio unit, the system integrates a 4-inch speaker, dual-channel amplifier (bridged for mono output), voltage regulation, and a custom wire harness for clean internal routing.

Designed for portability, durability, and quick serviceability.

Goal of the Project

Create a compact, portable boom box powered by standard drill batteries.
Deliver high-output mono sound using a 4-inch driver in a small footprint.
Design a fully self-contained housing optimized for additive manufacturing.
Develop a clean internal architecture with simplified wiring and serviceability.
Maintain a bold, minimal exterior aesthetic.

Obstacles

Integrating a drill battery interface while maintaining compact overall dimensions.
Managing heat dissipation from the amplifier and voltage regulator inside a sealed housing.
Controlling internal vibration caused by a high-output 4-inch driver.
Routing wiring cleanly without interfering with the removable battery interface.
Balancing portability (handle + form factor) with structural rigidity.

Design Limitations

Must be 3D printed.
Single primary housing body — no complex multi-shell assemblies.
Limited internal volume due to compact form factor.
Standard off-the-shelf electronics components (amp, regulator, switch).
16mm button switch required to fit within front panel constraints.
Battery geometry dictated enclosure proportions.
