Feedback reducing receiver mount and assembly
View Patent ↗A flexible support for a hearing instrument receiver suspended on a receiver tube in a hearing instrument housing will lessen the feedback that could be generated if the housing is jostled. A tether affixed to the receiver and anchored to the housing functions in this manner, and also improves the stability of the receiver inside the housing. Alternatively, a floating arrangement, where the receiver rotatably resides in a cradle may also offer feedback reduction and isolation for the receiver.
