Patent abstract
With a hearing aid device in a frame configuration, acoustic feedback is avoided with an opened battery charger. To this end, a seal surrounds the frame component in an annular manner, the seal sealing a gap between the frame component and the housing thus providing a more user friendly hearing aid.
