DIY Bluetooth 4.0 Speaker Kit

This DIY kit lets you build a portable wooden Bluetooth speaker without any soldering. It includes laser-cut wooden panels, two 2-inch 4-ohm 3-watt full-range drivers, a dual-channel Bluetooth amplifier board, and clear assembly instructions. The project is designed for STEM learning and suits children aged eight and above, teens, and adults who enjoy hands-on electronics.

Bluetooth 4.0 Wireless Connectivity

The amplifier board uses Bluetooth 4.0 to pair with phones, tablets, or computers for cable-free audio streaming. This single wireless standard decides whether the speaker works with your devices, so verify that your source supports Bluetooth 4.0 before purchasing. No other wireless protocols or wired inputs are included in the kit.

Battery-Powered Portable Build

The finished speaker runs on four user-supplied batteries, so no mains adapter or USB power bank is needed. You only need to provide the batteries and a Bluetooth audio source to start listening. The wooden enclosure arrives as flat-packed laser-cut pieces that you assemble yourself, keeping the build compact and self-contained.

Questions about this item

How does Bluetooth 4.0 affect the sound when the speaker is built and playing music?

Bluetooth 4.0 provides a wireless link from a phone or computer to the dual-channel amplifier board, delivering the audio signal that drives the two 3 W full-range speakers for stereo playback.

What does the Bluetooth 4.0 connection actually limit in daily use?

The Bluetooth 4.0 link caps the wireless range to roughly ten metres and limits the audio bandwidth to the standard SBC codec, so very high-resolution streams will be down-sampled before reaching the amplifier.

What must be supplied to power the finished speaker and make it portable?

Four batteries (not included) are required to power the amplifier board, allowing the assembled wooden cabinet to operate away from a mains outlet.
