Inflatable Earbuds



When using earbuds, the quality of sound transmission is impaired by the loose fit of the bud inside the ear canal. This new invention by Stephen Ambrose offers a solution:

The ADEL currently comes in two flavors — a "balloon" completely surrounding a driver unit, with the membrane replacing the entire structure of a traditional earphone, both the plastic, metal, or wooden housing and eartip; and a retrofit to existing eartips, in which small vent holes are drilled into the collar that fits around an in-ear phone's driver unit, then covered with small sections of membrane.

The diaphonic pump is a subminiature unit that can be mounted in line or on the tiny drivers used in earphones; in the balloon units it turns the otherwise wasted energy left over by the moving driver into inflation pressure to keep the membranes seated in the ear canals.
