EARPIECE ASSEMBLY WITH FOIL CLIP

摘要

Examples of a removable earpiece assembly configured for coupling to a canal hearing device using a foil-thin clip are described. The earpiece assembly may be readily removed for replacement when soiled or degraded after use. The earpiece assembly may include a compliant element for contact with the ear canal in a comfortable and safe manner. The earpiece assembly may function as an acoustic seal and/or a retainer for the canal hearing device. The removable earpiece assembly may provide a highly space efficient solution which may be used with miniature canal hearing devices, including a CIC device. In some embodiments, disengagement of the earpiece assembly from the canal hearing device may be accomplished by a side peel motion.

1. A seal assembly configured for removable attachment to a canal hearing device and adapted to provide acoustic sealing in the ear canal, the seal assembly comprising:
a clip element formed of metal foil having a thickness of 0.2 mm or less, wherein the clip element is configured to be attached to a rigid medial end of a canal hearing device encapsulating a speaker assembly therewithin, the clip element being deformable when the seal assembly is detached from the canal hearing device; and a relatively compliant seal element, at least partially concentrically positioned over the clip element, wherein the compliant seal element is configured to provide acoustic attenuation in the audiometric frequency range of 1,000 to 4,000 Hz.
