Audio Demonstration Kit

摘要

An audio demonstration kit encourages understanding of audio concepts by enabling children to construct and study speaker performance. In a particular example, the audio demonstration kit includes a paper speaker and instructions. The paper speaker includes a backplate, a suspension, and a diaphragm cut from a single sheet of paper. The demonstration kit may feature an amplifier that is configurable to accommodate various hardware additions as a child is ready for more progressively challenging construction. For example, the amplifier of an example allows single and dual mode operation, as well as drives a rotary motor and is coordinated with a strobe light. The amplifier of an example is synchronized with the strobe light and a moveable platform to create the impression of that jiggling figures attached to the table are dancing. Interfaces with smart phone, recording, and other technologies further enhances and encourages the learning experience.
