Abstract

In a Behind-The-Ear hearing aid (BTE hearing aid) the rotary volume control knob is partially exposed, whereas the amplifier circuit it is assembled to is located in the inside of the housing. Since this control knob is exposed for the user to adjust the volume, it sometimes happens that the user increases or decreases the hearing aid’s volume by accident. Moreover, because of the rotary control knob being exposed, there is a gap between the knob and the housing, where sweat, grease or other moistures can enter which is harmful to the instrument.

Waterproof Cover with Magnifying Glass for Behind-The-Ear Hearing Aid with Rotary Volume Control Knob

Idea: Swee Kim Chua, SG-Singapore

In a Behind-The-Ear hearing aid (BTE hearing aid) the rotary volume control knob is partially exposed, whereas the amplifier circuit it is assembled to is located in the inside of the housing. Since this control knob is exposed for the user to adjust the volume, it sometimes happens that the user increases or decreases the hearing aid's volume by accident. Moreover, because of the rotary control knob being exposed, there is a gap between the knob and the housing, where sweat, grease or other moistures can enter which is harmful to the instrument.

At present there are attachments designed to cover the knob in order to avoid changing the volume by accident. However, these attachments are not designed to have a waterproofing function and, at the moment, there is no solution known solving this special problem of BTE hearing aids with rotary volume control knobs.

A novel solution for the problems mentioned above is presented in the following. This solution consists of a waterproof cover system for the rotary volume control knob made out of transparent plastic and attached to the hearing aid housing by a hinge it pivots on. This assembly is depicted in Figure 1. A rubber gasket is placed around a groove in the cover as depicted in Figure 2, sealing up the gap whe...
