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. And, the flex-print may be used as a portion of the diaphragm subassembly and/or the backplate subassembly

Microphone having a flexible printed circuit board for mounting components

The present invention relates to an assembly comprising an electrical element, such as a coil, and especially to an assembly more easily assembled. Assemblies of this type are used for receivers for hearing aids or sound generators for e.g. mobile telephones.
