DIY Bluetooth speaker kit

This STEM kit lets children aged 10 to 12 build a working Bluetooth speaker from wooden parts and electronic modules. Assembly follows step-by-step instructions and requires no soldering. The finished speaker plays audio wirelessly from a paired device and runs on a rechargeable battery. It is designed for beginners who want a hands-on introduction to electronics and acoustics.

Upgrade from passive kits

Unlike static model kits, this set produces a functional audio device that can be used daily after assembly. The jump is worth it when a child wants a project that teaches circuit basics and delivers a tangible, reusable result rather than a display piece. Builders who need advanced programming or multi-driver audio will find the single-speaker design limiting.

Compact wooden enclosure

The assembled cabinet measures 4.9 by 2.8 by 4 inches and weighs 0.24 kilograms, fitting easily on a desk or shelf. The rechargeable battery provides roughly one hour of playback per charge, suitable for short listening sessions. Extended playtime or larger-room volume are beyond the capacity of the included driver and battery.

Questions about this item

What are the dimensions of the wooden speaker box that needs to be assembled?

The wooden speaker box measures 4.9 inches long, 2.8 inches wide and 4 inches high.

How is the Bluetooth module connected during assembly, and what step is often missed?

The Bluetooth module connects to the speaker driver using the supplied wires; the step often missed is securing the wire terminals firmly so the connection does not loosen when the box is closed.

What maintenance will the rechargeable battery need over time?

The built-in rechargeable battery will eventually hold less charge; when playtime drops noticeably, the whole speaker unit must be replaced because the battery is not user-replaceable.
