A hearing device comprising at least two microphones, a processor and an output for further processing in a reproducer, the microphones being electrically coupled to the processor, and the output for further processing in a reproducer being connected to the processor. The processor comprises: a summer providing a sum signal of the microphone signals, and to which summer a proportional amplifier is connected, and a summer for providing a difference signal of the microphone signals, to which summer an integrator is connected, and that the proportional amplifier and the integrator are coupled on the output side to a third summer providing a sum signal of the proportional amplifier and the integrator, and that the third summer forms the output for further processing in a reproducer.

Directional hearing device

An electroacoustic transducer of the electret type, having a backplate situated above a diaphragm, with the backplate being provided with spacers. The diaphragm is clamped on a frame-shaped carrier located at an underside of the diaphragm. The carrier is provided with supporting portions which are vertically aligned with the spacers. In one embodiment, supporting posts are formed on the supporting portions to allow the carrier to rest on a case bottom. The resulting electroacoustic transducer can be easily assembled with a reduced risk of damage.

Electroacoustic transducer

A transducer, in particular suitable for hearing aids, comprising a coil, two spaced magnet elements, a membrane, and an E-shaped armature, a middle leg of the E-shaped armature extending through the coil and the two magnet elements and being coupled with the membrane by means of a connecting element, limiting means being provided for limiting the maximum deflection of the middle leg of the E-shaped armature, which limiting means cooperate with the end of the middle leg of the E-shaped armature.
