Abstract

In most cases of receivers used in the hearing aid devices its spout is too short. Thus, the wrapping of the rubber receiver tube induces difficulty, because the seam of the wrapping region is prone to acoustic leakage if the rubber receiver tube does not seal the spout well. Also on the receiver casing, there is often a wrapping rubber receiver suspension to suspend the receiver. At present, the rubber receiver tube from the receiver spout to the metal socket (SOC) and the rubber receiver suspension are two separate parts.

Integrated Receiver Suspension with Protruded Tube for the Spout

In most cases of receivers used in the hearing aid devices its spout is too short. Thus, the wrapping of the rubber receiver tube induces difficulty, because the seam of the wrapping region is prone to acoustic leakage if the rubber receiver tube does not seal the spout well.

Also on the receiver casing, there is often a wrapping rubber receiver suspension to suspend the receiver. At present, the rubber receiver tube from the receiver spout to the metal socket (SOC) and the rubber receiver suspension are two separate parts.

Currently, to resolve the acoustic leakage at the seam of the wrapping region, polysiloxane (e.g. Coltoflax silicone) is applied to the seam region. However, this is not a good solution as it adds process variants in the manufacturing process. The current design of hearing aid receivers is shown in figure 1 on the left side.

In the following, it is proposed to prevent acoustic leakage at the seam of the wrapping region between the rubber receiver tubing and the receiver spout by an integrated receiver suspension with protruding tube for the spout. Additional, it is proposed to design the rubber receiver tubing from the receiver spout to the metal socket (SOC) an...
