Press-fit ear wax barrier |
摘要 |
An ear wax barrier for an in-the-ear or in-the-canal type hearing aid device positioned at least in part between a receiver output port and a shell acoustic output port includes a substantially cylindrical housing having a barbed portion for press-fitting the barrier into position. The barrier may include a screen and/or a plurality of undulations, such as a thread internal thereto for providing wax accumulation sites to retard the migration of wax into the hearing aid. The barrier is more easily inserted than removed.
