Power and signal transmission devices for auditory prosthesis
An auditory prosthesis can be powered by an on-board battery that is placed into a receptacle in the auditory prosthesis. When longer battery life is desired, a recipient can selectively utilize a discrete power supply to power the auditory prosthesis. The discrete power supply provides power to the auditory prosthesis and, in certain embodiments, has a longer life than the on-board battery. The discrete power supply includes an adapter having a form factor that mates with the battery receptacle on the auditory prosthesis.
1. An apparatus comprising:
a battery unit defining a battery unit receptacle for receiving a battery comprising a first form factor;
a cable extending from the battery unit; and
an adapter connected to the cable, the adapter configured to be matingly received in a housing battery receptacle, wherein the housing battery receptacle is configured to matingly receive a battery comprising a second form factor;
wherein at least a portion of the adapter is shaped to mimic the form factor of a disposable battery.
