Homemade speaker made with a toy motor /// Homemade Science with Bruce Yeany

This homemade speaker uses a toy motor instead of a coil of wire and a magnet.The amplifier wires are simply attached to a toy motor to make it vibrate. Use it to make a conductor speaker that only you can hear or attach it to a paper plate to make a simple speaker that will amplify the sound. Homemade science is a collection of classroom tested ideas, suggestions, projects, and experiments that I have used in teaching physical science for the Annville-Cleona school district in central Pennsylv
