Abstract

The external volume control of a BTE hearing aid (BTE: Behind-The-Ear) for adjusting the sound volume has usually the form of a rotary knob or a pair of pushbuttons. Such a hearing aid is designed to have either a rotary knob or pushbuttons. However, the volume controller is not replaceable. It is advantageous to have volume controls in form of interchangeable modules, so that the user can chose the preferred controller and change it if desired. In addition, more flexibility in the manufacturing is provided by using these interchangeable modules. In the following a novel solution for a BTE hearing aid with modular volume control is proposed and depicted in Figure 2 to Figure 8. The solution consists of: i. A BTE hearing aid with an internal frame cut out to accommodate the control modules and slots to guide and hold the plug-in module in the right place.

Behind-The-Ear Hearing Aid with Interchangeable Volume Control Input Modules

Idea: Swee Kim Chua, SG- Singapore

The external volume control of a BTE hearing aid (BTE: Behind-The-Ear) for adjusting the sound

volume has usually the form of a rotary knob or a pair of pushbuttons. Such a hearing aid is designed

to have either a rotary knob or pushbuttons. However, the volume controller is not replaceable.

It is advantageous to have volume controls in form of interchangeable modules, so that the user can

chose the preferred controller and change it if desired. In addition, more flexibility in the manufacturing

is provided by using these interchangeable modules.

In the following a novel solution for a BTE hearing aid with modular volume control is proposed and

depicted in Figure 2 to Figure 8. The solution consists of:
i. A BTE hearing aid with an internal frame cut out to accommodate the control modules and slots

to guide and hold the plug-in module in the right place.
ii. Removable top casing using metal pins to attach.
iii. The BTE hearing aid includes a main PCB (Printed Circuit Board) with exposed pads according

to the pins on the interchangeable modules. Because of the different contact pins, the main

circuitry is able to detect which kind of module is used. Further contacts are used for power,

grounding and signal lines.
iv. A pushbutton plug-in module which consists of a frame, a PCB with two tact-switches for

controlling the volume, a jumper connection circuit giving a signal that the push-button module is

used, and a mechanical push-button that rotates around a axle pin
v. A rotary knob volume control module which consists of a frame, an analogue potential divider

volume control knob, and a jumper connection circuit giving a signal that the analogue volume

control is used. The frame can be colored in order to match the color of the casing.
vi. A rotary knob volume control module is used. It consists of a frame, a digital encoder volume

control knob and a jumper connection circuit giving a signal that the digital volume control is

used. The frame can be colored in order to match the color of the casing.
vii. For other applications, the module can be built with a single button. This button can be used as
