Abstract

The large inventory of manufacturing parts of Behind the Ear hearing aids (hereinafter referred as BTE) is caused only by variations of the battery contact. For example, one particular BTE has three kinds of battery contacts; which are the normal type, the charging type, and the smaller version for a special miniaturized model. In the following a common battery connection concept for different BTE models is proposed. In this solution, the connection of the negative contact is guided over the battery compartment hinge and the appropriate axle which is also conductive. The inside, for example, of the top hinge cup has a conductive surface which is connected to the power supply of the hearing aid (Figure 1). The current flows over the axle to the middle hinge cup which is fixed to the battery compartment and also provided with a conductive inner surface (Figure 2). This surface is connected to the negative contact of the battery.

Innovative Concept for Battery Connections in BTE Hearing-Aids

Idea: Chee Wah Leong, SG-Singapore

The large inventory of manufacturing parts of Behind the Ear hearing aids (hereinafter referred as

BTE) is caused only by variations of the battery contact. For example, one particular BTE has three

kinds of battery contacts; which are the normal type, the charging type, and the smaller version for a

special miniaturized model.

In the following a common battery connection concept for different BTE models is proposed. In this

solution, the connection of the negative contact is guided over the battery compartment hinge and the

appropriate axle which is also conductive. The inside, for example, of the top hinge cup has a

conductive surface which is connected to the power supply of the hearing aid (Figure 1). The current

flows over the axle to the middle hinge cup which is fixed to the battery compartment and also

provided with a conductive inner surface (Figure 2). This surface is connected to the negative contact

of the battery.

The connection for the positive contact between the battery and the power supply is realized by a

current collector which is fixed to the main frame of the hearing aid (Figure 4) and connected directly

to the positive contact of the battery. Therefore an aperture is placed at the side of the compartment

(Figure 3). By turning the battery compartment to its designated position at the hearing aid, the

positive contact will be connected.
