Build Your Own Bluetooth Stereo Speaker from Scratch

Take your electronics skills to the next level with this DIY Bluetooth Stereo Speaker Kit. Perfect for students, hobbyists, and educators, this hands-on soldering project teaches real-world circuit assembly while producing a fully functional, great-sounding Bluetooth speaker housed in a stunning transparent acrylic shell. Made in Mainland China.

Key Features

• Bluetooth Wireless Audio: Pair instantly with any smartphone or tablet. The kit connects as "XC 046" — simply find and connect. When Bluetooth disconnects, it automatically switches to USB flash drive playback.
• 3W + 3W Stereo Output: Dual-channel amplifier delivers clear, full-frequency sound through 40-magnet, 4Ω 3W speakers with PU-edged silver-black diaphragms for impressive clarity and depth.
• Multiple Playback Modes: Supports Bluetooth streaming, USB flash drive music playback, and auto power-off memory — so it remembers your last source when powered back on.
• Remote Control Included: Adjust volume and control power on/off conveniently with the included remote.
• Rhythm-Synced LED Lights: Voice-activated LED lights pulse and flow in sync with the music — the louder the sound, the brighter and faster the light display.
• Premium Acrylic Shell: Assembled from 6 pieces of 3mm high-transparency acrylic for a sleek, modern look. Simply peel the brown protective film before splicing together.
• USB-Powered Convenience: Runs on 5V DC (4.2–5V) via a standard USB power cable (included). Compatible with phone chargers or PC USB ports. Recommended power supply: 5V/2A for best sound quality.

Frequently Asked Questions

Q: Do I need soldering experience to assemble this DIY Bluetooth speaker kit?

A: Basic soldering knowledge is helpful. The Bluetooth circuit board comes pre-soldered, so you mainly need to connect the wiring and assemble the acrylic shell and sound control board. It's ideal for beginners learning electronics assembly and soldering techniques under guidance.

Q: What power supply do I need for the DIY Bluetooth speaker kit?

A: The kit requires a 5V DC power supply (4.2–5V range). A standard 5V/2A USB phone charger or computer USB port works perfectly. Do NOT use a voltage exceeding 5V, as this can damage the module. A 2A current supply delivers the best audio quality.

Q: Can this Bluetooth speaker kit play music from a USB flash drive?

A: Yes! When Bluetooth is not connected, the kit automatically switches to USB flash drive playback mode. Simply insert a USB drive with your music files and it will begin playing automatically.

Q: What does the LED light feature do on this DIY speaker kit?

A: The kit includes a voice-activated LED melody light circuit. The LEDs pulse and flow in rhythm with the music or any surrounding sound — the louder the audio, the brighter and faster the light display, creating a dynamic sound-and-light experience.
