Voice Changer Kit

Wesley Henderson

For the Fall 2005 Music Technology course, I decided to do an electronic project. The project I chose was a voice changer kit. It required the use of a soldering iron, several different resistors, ceramic caps, capacitors, a microphone, battery snaps, PC board, and speaker. The project turned as good as expected. There were no major problems in the assembly of the project. There was, however, a few spots where there wasn't much room to solder without having any bridges. The kit could of come with a longer speaker wires because the feedback was very overwhelming. With the speaker only being about a foot and half away from the board and microphone, the feedback overpowered the sound. As you can see with the picture, there are five little buttons at the bottom of the board. They each give a different effect while you are talking into the microphone when pressed. The first button changes te voice to a higher pitch, the second button changed the voice to a lower pitch, the third gives a lower vibrato sound, the fourth gives an upper vibrato sound, and the fifth gives a robotic sound. All in all this was a fun project. I wish there wouldn't have been as much feedback while trying to demonstrate, but other than that everything went as expected.
