Laser Cut Bluetooth MP3 Speaker w FM Radio

The speaker driver I used is a closed-type unit. It doesn't need a close box for sound resonance. So I made the design simple, with a laser cut acrylic front and back cover only.

This is the second version. The PCB board has been upgraded, which includes MP3 Playback, bluetooth reception and FM radio.

The speaker uses 5V DC for power. We may use a power bank or phone charger to power it up.
