Mechanism for external multi-functional cable retention for a hearing device
A hearing device configured to be worn in an ear of a wearer includes a first housing component defining a recess, a second housing component configured to attach to the first housing component to define an enclosure, and a conductor, and a multi-function cable. The multi-function cable includes a blunt feature and an outer jacket of a multi-function cable. The outer jacket extends through the first housing component. A passage is defined by the blunt feature and the outer jacket, and the conductor extends through the passage. The hearing device further includes a plurality of fibers secured to an inner surface of the passage and an inner surface of the enclosure. The fibers extend through the passage and are configured to transfer mechanical forces from the multi-function cable to the first housing component.
