IPOD Speakers

A few companies, including Victor Talking Contraption Aggregation and Pathe, produced record players using compressed-air loudspeakers. However, these designs were significantly limited by their poor total nature and their inability to reproduce substantial at low volume. Variants of the combination were used for public address applications, and fresh recently other variations have been fond to test gap equipment resistance to the very loud sound and vibration levels that launching rockets produce.

The diaphragm is occasionally manufactured with a cone or IPOD Speakers dome shaped profile. A variety of different materials may be used, but the most bourgeois are paper, plastic and metal. The ideal material would be stiff (to block uncontrolled cone motions), light (to minimize starting arm requirements) and well damped (to reduce vibrations continuing after the signal old-fashioned stopped). In practice, all three of these criteria cannot be met simultaneously using existing materials, and thus driver chart involves tradeoffs.
