Boom Box Music Player

If you don't have amplifier, don't worry

Here is circuit diagram.

---components for amplifier---

IC-TDA2007A

R1-1.3Kohm

R2-18ohm

R3-1.3Kohm

R4-18ohm

R5-1ohm

R6-1ohm

C1-2.2µF

C2-2.2µF

C3-22µF

C4-0.1µF

C5-100µF

C6-220µF

C7-220µF

C8-0.1µF

C9-0.1µF

C10-2200µF

C11-2200µF

soldering all components as per circuit diagram on PCB.

Here i designed this model.and cut the plywood.and joined it. I use wooden glue to join all parts.

and i use drilling machine to cut circles foe speakers.

Notice--

-be careful when you use of wooden saw.

here i use plan paper to cover all wooden body.

all ON/OFF switches,push switches, 3.5mm female audio jack,usb mp3 player module stick on wood.

Here i shows you basic block diagram.

Power supplying all things..

now two wires comes from AC socket,one of them hot wire and another one is neutral wire.

Here we place one (s1)switch at hot wire and connect both to the power supply.

Then after output of power supply set at 12v, And connect +terminal to any one terminal of (s2)switch and second terminal of switch connect Amplifier Vcc. And the GROUND terminal connect ground of the amplifier.

here we have 12v power supply we should have to need to regulate it to 5v.

Here we can use LM7805 ic to do it.

now connect positive(+) terminal of 12v to 1 pin of ic.

And ground to 2 pin

Then we get 5v to the output pin 3.

For more details of LM7805 IC click here.

After doing this process supply 5v to he Bluetooth and mp3 module put separate switches to Bluetooth module and mp3 player module.

Bluetooth module output is connect to the input of Amplifier.

Now mp3 player module have 3 pins of

G-ground

R-right

L -left

this is audio output pins.

connect it G to amplifier's input ground,R to right and L to left of amplifier input.

all connection of mp3 player module shows in figure.

now connect Amplifier inputs to 3.5mm female audio jack

Fix the speakers and other parts using screws.

and DONE.

BOOM BOX IS READY.
