Abstract

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.

First claim

The invention claimed is:

1. An audio demonstration kit comprising:
a first enclosure configured to store and attach to a first plurality of components of the audio demonstration kit;
a second enclosure configured to store and attach to a second plurality of components of the audio demonstration kit, the second enclosure enclosed within the first enclosure to form a packaged audio demonstration kit; and
an amplifier attachable to the first plurality of components and to the second plurality of components and enclosed within the packaged audio demonstration kit, wherein the amplifier attached to the first plurality of components and the second plurality of components forms a user-built speaker,
wherein the amplifier attached to the first plurality of components and the first enclosure forms a first speaker of the user-built speaker,
wherein the first speaker comprises a single sheet of paper defining a first 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 wire coil, the magnet, and the diaphragm form a first acoustic transducer of the first speaker, and
wherein the amplifier attached to the second plurality of components and the second enclosure forms a second speaker of the user-built speaker.

2. The audio demonstration kit of claim 1 , wherein the amplifier includes at least one of a tone control and a volume control.

3. The audio demonstration kit of claim 1 , wherein the amplifier comprises an input configured to receive audio signals from an external device.

4. The audio demonstration kit of claim 1 , wherein the first acoustic transducer comprises a bobbin to guide wrapping a wire to form the wire coil.

5. The audio demonstration kit of claim 4 , wherein the first acoustic transducer is formed by winding the wire around the bobbin to form the wire coil and positioning the wire coil around the magnet of the first transducer, wherein the magnet of the first transducer is a cylinder magnet.

6. The audio demonstration kit of claim 1 , wherein the amplifier includes a connector configured to receive power from a power supply.

7. The audio demonstration kit of claim 1 , wherein the back support, the suspension, and the diaphragm are formed by respective portions of the first enclosure.

8. The audio demonstration kit of claim 1 , wherein the second plurality of components include a second acoustic transducer, wherein the second acoustic transducer comprises a bobbin to guide wrapping a wire to form a wire coil.

9. The audio demonstration kit of claim 8 , wherein the second acoustic transducer is formed by winding the wire around the bobbin to form the wire coil and positioning the wire coil around a magnet of the second transducer, wherein the magnet of the second transducer is a cylinder magnet.

10. The audio demonstration kit of claim 1 , wherein walls of the second enclosure form a back support, a suspension, and a diaphragm.

11. The audio demonstration kit of claim 1 , wherein the first acoustic transducer is configured to receive a first signal from a first output of the amplifier.

12. The audio demonstration kit of claim 1 , wherein the second plurality of components comprises a second acoustic transducer, wherein the second acoustic transducer is configured to receive a second signal from a second output of the amplifier.
