  • Moving armature receiver
    Patent number: 8223996
    Abstract: A compact moving armature receiver where the diaphragm element is positioned in the air gap of the magnet assembly and where a suspension element is provided for defining the front chamber, the suspension element has a stiffness of at the most 500 N/m. The suspension element and the diaphragm element may be made from the same sheet of a foil, and the suspension element may be formed by bent or curved peripheral parts of the foil.
    Type: Grant

  • Microphone assembly for hearing aid with JFET flip-chip buffer
    Publication number: 20020090102
    Abstract: A hearing aid microphone module housing all the electronic components needed for a functional hearing aid other than the battery and receiver is described which uses flip-chip technology to couple a JFET buffer to the components. The buffer is disposed on a PCB which defines a back volume of the housing.
