Abstract:
A hearing aid has hearing aid electronics including the microphone, battery and amplifier in a behind-the-ear housing, with a flexible tube extending from the behind-the-ear housing to a concha-based suspension structure. The concha-based suspension portion is flexible and bears off a tragus contact area, an antitragus contact area and an antihelix contact area. Based on forces generated from these concha bowl contact areas, the tube is suspended in a centered position within the ear canal in an unoccluded fashion making little or no contact with the wall of the ear canal. An annulus of the suspension portion provides an open concha skin surface, which can naturally reflect sound down the generally open ear canal.
