US 2014/0153755 A1 · HEARING DEVICE WITH A TRANSDUCER MODULE AND METHOD FOR MANUFACTURING A TRANSDUCER MODULE

Abstract

The present invention proposes a hearing device with a housing and a receiver module which comprises a shell (16) with a cavity having an opening (17), wherein at least part of the shell (16) forms part of the housing, and wherein an electro-acoustic transducer, comprising a motor assembly (2) and an acoustic assembly (3) including a membrane, is arranged within the cavity, the acoustic assembly (3) being disposed within the shell (16) such that the cavity is divided into a front chamber (12) and a back chamber (13), the motor assembly (2) being disposed within the back chamber (13) or the front chamber (12) and being operatively coupled to the membrane, and the front chamber (12) being in acoustic communication with the exterior of the shell (16) via the opening (17), wherein the shell (16) has an outer surface individually shaped according to a measured inner shape of a section of an ear canal of a user of the hearing device. Furthermore, a method for manufacturing such a receiver module is presented.
