Audio demonstration kit
First Claim
1. An audio demonstration kit comprising:
- a single sheet of paper defining a paper speaker including;
a back support;
a suspension; and
a diaphragm configured to be driven by a wire coil directly connected to the diaphragm and a magnet coupled to the back support,wherein the single sheet of paper is folded such that the wire coil is positioned proximate the magnet;
a rotary motor; and
an amplifier configured to switch between providing an audio signal to operate the paper speaker and providing a current to operate the rotary motor.

Abstract
An audio demonstration kit encourages understanding of audio concepts by enabling children to construct and study speaker performance. In a particular embodiment, 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 embodiment allows single and dual mode operation, as well as drives a rotary motor and is coordinated with a strobe light. The amplifier of an embodiment 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.
