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.
Step 1: Get Donor Speakers
Get old desktop speakers or any pair of powered speakers. Small enough to fit in to the box that you have chosen.
Step 2: Disassemble
Carefully remove the drivers, transformer and the circuit and any other components.
Step 3: 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)
Step 4: Time to Add the Amplifier, Transformer & Drivers in the Charging Station.
Step 5: 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.
Step 6: Place the Components Inside.
Tape any exposed wires with electrical insulating tape & carefully place the amplifier along with speakers.
Step 7: Make Speaker Grill
Take any reference and make holes to make it look like a speaker grill.
Step 8: Mark on Both Sides.
Or if you want to go creative, go ahead and make any design you like.
Step 9: Mark the Dots. (again, Use Your Creativity)
Step 10: Make Holes With Soldering Iron
Make holes on the dots with the soldering iron. (Do not inhale any resulting fumes)
Step 11: Clean It Up a Bit.
It could get messy, shave of excess plastic with blade, knife or a steel ruler.
Step 13: 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.
