H04R 2502

US Classification:

381 686

Abstract:

The present invention comprises an apparatus and method for inserting into, orienting within, and withdrawing from an ear a hearing aid, earphone, transducer, microprocessor, radio, sensor, or other mechanical or electronic device. The apparatus includes a housing attached to and containing the device. The housing has slots in which a handle, which is secured inside the housing, can slide. A magnet placed proximate the handle causes the handle to slide out, away from the housing, making it easy to grasp. The device can thus be inserted in, oriented within, or withdrawn from the ear by use of the handle. In its rest position, the handle lies flush against the housing making it almost visually imperceptible.
