Cellphone Charging / Music Station (Reuse Old Desktop Speakers)

100_0608.JPG
I decided to use my old desktop stereo speakers & incorporate them in my charging station, so i can play my music with more bass. (A lot better than cellphone's loudspeaker) + can be used as an extremely loud speakerphone or  an extremely loud alarm clock.

Get old desktop speakers or any pair of powered speakers. Small enough to fit in to the box that you have chosen.

Disassemble

Carefully remove the drivers, transformer and the circuit and any other components.

What We Need. Bare Essentials.

After taking out all the components, cut of excess wires (AC mains & Line in) & make them short. and remove other stuff that you don't feel is useful. (like knobs and screws)

Time to Add the Amplifier, Transformer & Drivers in the Charging Station.


OK, from where did the charging station come from? Here. My earlier project. Please watch.

Connect the Components

The picture explains it i think. I know it doesn't look safe, but it is. I was worried about the transformer melting the plastic. I was relieved that it doesn't heat.

Place the Components Inside.

Tape any exposed wires with electrical insulating tape & carefully place the amplifier along with speakers.

Make Speaker Grill

Take any reference and make holes to make it look like a speaker grill. 

Mark on Both Sides.

Or if you want to go creative, go ahead and make any design you like.

Mark the Dots. (again, Use Your Creativity)

Make Holes With Soldering Iron

Make holes on the dots  with the soldering iron. (Do not inhale any resulting fumes)

Clean It Up a Bit.

It could get messy, shave of excess plastic with blade, knife or a steel ruler.

Place the Lid.

Done!

Done! Now it can be used to play your favorite tunes, radio, or as a speakerphone or put it on high volume and make sure you wake up in the morning! 

Note: I could have put the volume controls on the outside if i wanted, but i want to make it look clean. So I kept the vol (on the amplifier) at 80% & set my desired volume through the Phone.
