Abstract

To control the amplification of the received sound, hearing aids normally have a volume control wheel which enables the user to adjust the volume manually. To prevent any accidental activation or sudden increase of the volume during daily use, the volume control of current hearing aids can be disabled or they have a limited volume range. In the following it is proposed to include a lock mechanism for the volume control wheel of BTE hearing aids (BTE: Behind-the-Ear). By using for example an axle, the movement of the volume control wheel can be fixed automatically and any accidentally activations are prevented (Figure 1). To use the volume control wheel, the wheel has to be pressed by an outside force to be unlocked (Figure 2).

To control the amplification of the received sound, hearing aids normally have a volume control wheel which enables the user to adjust the volume manually. To prevent any accidental activation or sudden increase of the volume during daily use, the volume control of current hearing aids can be disabled or they have a limited volume range.

In the following it is proposed to include a lock mechanism for the volume control wheel of BTE hearing aids (BTE: Behind-the-Ear). By using for example an axle, the movement of the volume control wheel can be fixed automatically and any accidentally activations are prevented (Figure 1). To use the volume control wheel, the wheel has to be pressed by an outside force to be unlocked (Figure 2).

The advantage of the proposed solution is that there are no accidental activations and in consequence no sudden increase of the volume due to careless handling. Thus, the volume control range can be increased. Furthermore, the proposed solution can be implemented for child lock purposes. The proposed solution, of using an axle to lock the volume control, can be manufactured easily due to few parts...
