Abstract

In the ear hearing aid instruments (ITE) are increasing in size due to size of the wireless coil and wireless coil holder. In existing custom wireless hearing instruments the coil holder is designed with a fixed angle of approximately 40-50 degrees. Hence, there is no flexibility to fit the shell assembly (see Figures 1 to 3).

Adjustable Wireless Coil Holder for ITE Instruments

Idea: Bashkaran Subramanian, SG-Singapore

In the ear hearing aid instruments (ITE) are increasing in size due to size of the wireless coil and

wireless coil holder. In existing custom wireless hearing instruments the coil holder is designed with a

fixed angle of approximately 40-50 degrees. Hence, there is no flexibility to fit the shell assembly (see

Figures 1 to 3).

In the following a novel design for the coil holder is proposed where the coil holder is split into two

pieces (see Figure 4). One piece has a round slot to hold the upper piece that holds the wireless coil.

The bottom pieces can be glued to the faceplate and the upper piece can be fixed into the round slot

of the bottom piece. The round groove allows the upper piece to rotate around 160 degrees. This

results in a more flexible solution compared to state of the art systems. By further improvements of the

proposed design an angle up to 180 Degrees can be achieved.

The proposed solution does advantageously enable an optimal fitting of the wireless assembly with

the shells of the hearing instrument due to the enhanced adjustability. The system can be easily

mounted to the faceplate by glue.
