Modular connection assembly for a hearing assistance device
The present subject matter relates to an improved connection assembly for hearing assistance devices. The improved connection assembly provides a connection system that is reliable, straightforward to manufacture, and easy to use. The present connection assembly provides a rapid replacement option for the cable and/or the receiver or other electronics connected to the cable. The present subject matter provides for a connection assembly that can be extended to provide connections for a variety of applications which are not limited to a speaker (receiver) in the ear. Sensors and new configurations of component placement are supported using the present assembly, including, but not limited to telecoils, and GMR or TMR sensors. Various electromagnetic interference issues are addressed. In some examples a shielded set of wires are included. In some examples a twisted pair of wires is included. Various combinations of wires for different applications are supported with the present connector system.
