Title:
INFLATABLE EAR MOLD CONNECTION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2012/007508
Kind Code:
A3
Abstract:
An inflatable ear piece (4) is formed for insertion and placement in an external auditory canal (2). The ear piece has an inflatable balloon (7) that may be selectively inflated and deflated. When the balloon is inflated, it expands and braces against the walls of the auditory canal (2). The ear piece has a receiver module (5) with a sound generator (12) and a connection to an exterior device (e.g., a hearing aid, an MP3 player, a cell phone). The sound waves generated in the receiver module are guided to the ear drum (3) via a carrier (6) which also holds the balloon (7). A pump and valve assembly is integrated in the receiver module, for inflating, or selectively deflating, the balloon (7). The pump is connected by way of a micro tube that projects centrally inside the sound channel of the balloon carrier (6) and its tip projects into a radial projection (10) or a bridge across the sound channel. The receiver module (5) and the balloon module (6, 7) are rotationally symmetrical relative to one another, that is, they may be connected in any rotational orientation.
