bluetooth speaker 3d printer

thingiverse

It's a 3D printed Bluetooth speaker, controlled with the TDA7492P PCB board that includes all necessary functions, delivering power to two speakers of 25 watts and a maximum volume of 33 decibels. The board and speakers can be found on Amazon or AliExpress, requiring a 12-volt 5-amp power supply for operation. On the back cover, opposite the speakers, acoustic insulation must be placed to prevent reverse sound waves from damaging the sound quality. A simple on/off switch and a 12-volt power connector should also be installed in this cover, available at any electronics store. The speakers are secured with M3 screws, while other parts are attached with hot glue. Ensure they're fixed well when placing the TDA7492P board, centered with button holes.
