Summary: Audio speakers are an everyday item in todays world found in televisions, computers, stereos, etc. This project is designed to teach a student about how sound is generated using electrical currents and magnetic fields to produce pressure differentials perceived by humans as sound. Students construct a speaker from raw materials such as magnets and wire while learning vital concepts that describe the theory behind sound generation. A speaker is a very tangible object that most students are familiar with and have interest in developing their own version. The finished product is a speaker through which a student can listen to their favorite song or whatever they please. |
