Patent number: 8218803Abstract: In the case of a receiver facility to be fixed in the auditory canal, particularly for hearing devices with an external receiver, the receiver is to be mounted in the earmold in an acoustically advantageous fashion which guards against contaminations and is also easily exchangeable. Provision is thus made for a receiver facility with a longish receiver and a earmold, which has a borehole, into which the receiver is inserted. A tubular connector, which is more elastic than the receiver and the earmold, is used to accommodate for the most part the longitudinal extension of the receiver in a friction-locking fashion. The connector is for its part force-fitted into a borehole of the earmold in a friction-locking fashion. The receiver is thus elastically mounted and can be easily removed from the earmold together with the connector with the aid of a pin-like tool for replacement purposes.Type: GrantFiled: August 5, 2008Date of Patent: July 10, 2012Assignee: Siemens Medical Instruments Pte.
