  • HEARING DEVICE HAVING A NON-OCCLUDING IN THE CANAL VIBRATING COMPONENT
    Publication number: 20100222639
    Abstract: A self-retaining bone conduction hearing device having a sound processor (104) and a nonoccluding in-the-canal vibrating component (108) responsive to the sound processor and configured for non-surgical-implantation in a recipient's ear canal. Utilizing bone conduction eliminates the dependency on acoustic stimulation, thereby enabling the hearing device of the present invention to address a wider range of sound frequencies in conductive hearing loss.

  • Convex folded shell projector
    Publication number: 20050152222
    Abstract: An acoustic projector comprising a pair of spaced apart end plates with an acoustic driver positioned between the end plates. The end plate's edges are secured to an outer one-piece thin walled shell that provides an enclosure for the driver. That thin walled shell has a convex outwardly bent surface between the end plates and a plurality of axially extending corrugations to provide a predetermined axial compliance and radial-to-axial transformation ratio.
