ABSTRACT:
The invention provides a replaceable handle for hearing devices that are deeply inserted into the ear canal. The handle is offered in an assortment of configurations to optimize the hearing devices cosmetic appeal and usability. The handle consists of a shaft, handle head and a locking end for insertion into the lateral end of a hearing device. The locking mechanism of a preferred embodiment consists of two inwardly flexible legs that compress while being inserted sideways into a locking receptacle within the lateral end of the hearing device. The legs spring back when they have been fully inserted, thus locking the handle to the hearing device. The handle remains securely attached to the device during normal use, which primarily subjects the device to axial or push/pull forces. However, the handle can be readily removed by opening the battery door and sliding the handle sideways into the cavity of the battery compartment.
