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.

First claim

The invention claimed is:

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.

2. The audio demonstration kit of claim 1 , wherein the single sheet of paper includes a set of instructions directing assembly of the paper speaker.

3. The audio demonstration kit of claim 2 , wherein the set of instructions includes an instruction to fold the single sheet of paper along a line indicated on the single sheet of paper.

4. The audio demonstration kit of claim 2 , wherein the set of instructions includes an instruction to attach a first portion of the single sheet of paper to a second portion of the single sheet of paper.

5. The audio demonstration kit of claim 2 , further comprising a bobbin and a wire, the bobbin configured to guide wrapping the wire to form the wire coil.

6. The audio demonstration kit of claim 5 , wherein the bobbin comprises a cylinder bobbin.

7. The audio demonstration kit of claim 6 , wherein the set of instructions includes instructions directing assembly of the wire coil by winding the wire around the bobbin.

8. The audio demonstration kit of claim 7 , wherein the single sheet of paper indicates a location at which to attach the wire coil directly to the single sheet of paper at a location of the diaphragm.

9. The audio demonstration kit of claim 1 , wherein the amplifier is connectable to the paper speaker.

10. The audio demonstration kit of claim 9 , further comprising at least one cable configured to connect the amplifier to the paper speaker.

11. The audio demonstration kit of claim 9 , wherein the amplifier includes at least one connector that corresponds to at least one output audio channel.

12. The audio demonstration kit of claim 11 , wherein the amplifier includes a first connector corresponding to a left audio channel and a second connector corresponding to a right audio channel.

13. The audio demonstration kit of claim 9 , wherein the amplifier includes a tone control, a volume control, or a combination thereof.

14. The audio demonstration kit of claim 9 , wherein the amplifier includes a connector configured to receive power from a power supply.

15. The audio demonstration kit of claim 9 , wherein the amplifier includes an input configured to receive audio signals from an external device.

16. The audio demonstration kit of claim 1 , wherein the single sheet of paper includes a first tab corresponding to the back support and multiple suspension tabs corresponding to the suspension, wherein at least one of the suspension tabs is narrower than the first tab such than an opening is defined between two or more of the suspension tabs when the paper speaker is assembled.

17. The audio demonstration kit of claim 1 , further comprising the magnet, wherein the magnet is a cylinder magnet.

18. The audio demonstration kit of claim 17 , wherein the single sheet of paper indicates a location at which to attach the cylinder magnet to the single sheet of paper, the location corresponding to a portion of the back support.

19. An audio demonstration kit comprising:
a magnet;
a bobbin;
a wire; and
a single sheet of paper defining a paper speaker including:
a back support;
a suspension; and
a diaphragm configured to be driven by a coil of the wire directly connected to the diaphragm and the 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.

20. An audio demonstration kit comprising:
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 a 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.
