  • Patent number: 7239714
    Abstract: In a microphone cartridge, a flexible printed circuit board serves two functions, separating the diaphragm and backplate, and electrically connecting the cartridge and the buffer amplifier. The flex-print includes a spacer portion that maintains the appropriate distance between the diaphragm and backplate, and an integral lead portion having a conductor serving as the signal path for transmitting the signal from the cartridge to the amplifier. The spacer portion has a conductor that electrically contacts the diaphragm or backplate and is connected to the conductor of the integral lead portion. The integral lead portion may optionally include a second electrical conductor providing a reference path from the cartridge to the amplifier. Further, the flex-print may be used as the carrier for the amplifier, its associated circuitry, and for other circuitry within the listening device.
