BEATBOXING WITH HOMESPUN SOUND BOX:

Author: Ranaprathap Ponnam (High school graduate)

This sound box is a best-out-of-waste invention. The outer material is a used water can. Some of the electronics are picked up from damaged devices, while the others were purchased separately. The speaker has a Bluetooth kit, a woofer, subwoofer, tweeter. It is powered with a 12V AC supply, which can also be powered with a battery. The internal PCB board is a two-channel 4440 IC as audio power amplifier board. The IC4440 has a built-in bass, treble and volume controls. The 100k ohm potentiometer is used for the bass control and two 47k ohm potentiometers are used for treble and volume control. The speaker has an aux-in and a 6.3mm jack socket as inputs and are soldered manually to the audio board. The output sources i.e woofer, subwoofer and tweeter are also manually soldered to the audio board. This has been built for personal practice purposes as buying one from the market was not affordable.

FUTURE IMPROVEMENTS:

-> We are looking to add reverb and echo controls to our speaker. -> We are looking to also add a RCA connector, through which this speaker can be connected to TVs for external audio.
