In this instructable, I 'll show you how I converted my ordinary speakers into an MP3 speaker.
The MP3 player gets its power from the speaker power source.

Stuff You Need

7805 --- 5 V Voltage Regulator from Amazon or eBay Here

USB Female Connector - - I used an old USB Male/Female Cable and cut it from the Female side . get it from Amazon or eBay Here
MP3 Player
Soldering iron get it from Amazon or eBay Here
Wires
Tape
Start Working
Open the Speaker from the power supply side.
Connect wires to the voltage regulator.
Insulate the regulator and wires with tape.
Find the 9 Volts DC coming from the rectifier circuit after the transformer , diodes and capacitors. This should be the input of the regulator.
Find the ground of the circuit. This will be connected to the ground terminal of the regulator and the negative terminal of the USB connector.
Weld the wire connected to the input terminal of the regulator with the 9 Volts point you found earlier.
Weld the wire connected to the regulator Ground to the Ground point you found earlier.
Mount the USB Connector
Close the Speaker and Use the MP3
