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.

An assembly for demonstrating sound transmission properties includes a base portion and a tray portion partially defining a transmission aperture is removably inserted into a portion of the base portion. A first sound-reducing tile having a first sound transmission property is placed in the tray portion and a sound generating device disposed in an interior volume of the base portion emits sound that is attenuated by the first sound-reducing tile as the sound exits the transmission aperture. A second sound-reducing tile having a second sound transmission property is placed in the tray portion and the sound generating device disposed in the interior volume of the base portion emits sound that is attenuated by the second sound-reducing tile as the sound exits the transmission aperture. A sound measuring device disposed outside the interior volume device can compare the first and second sound transmission properties.
