Publication number: 20160037272Abstract: A microphone module latching configuration for fixing a microphone module in a hearing instrument housing is formed at least partly of elastic material and has a planar extended basic shape, upper side, underside and a fixing device on the upper side to be brought into mutual, form-locking engagement with the microphone module, suppressing movement thereof relative to the latching configuration along its planar extent. A positioning device on the underside is brought into mutual, form-locking engagement with a microphone holder of the housing, suppressing movement of the latching configuration along its planar extent relative to the microphone holder, increasing structural freedom of the connection between latching configuration, microphone module and hearing instrument housing. The connection by fixing and positioning devices on the upper or underside eliminates a lateral holder or connection surrounding the microphone module, making the configuration slimmer.Type: ApplicationFiled: July 30, 2014Publication date: February 4, 2016Inventors: ANTON GEBERT, ULI GOMMEL, CHUAN FOONG LEE
