摘要：
An integrated headpiece for a cochlear implant system includes a microphone for outputting an audio signal； signal processing electronics for processing the audio signal； and a transmitter for transmitting a processed audio signal received from the electronics to an implanted receiver. All of the microphone, signal processing electronics, and transmitter are disposed in a common housing of the integrated headpiece. The headpiece may also be one of a set of headpieces that can be alternatively used as needed to suit power consumption requirements or environmental conditions.Cochlear implant systems include a circuit board having electronic circuitry configured to generate one or more signals configured to direct electrical stimulation of one or more stimulation sites within a patient, an induction coil configured to transmit a telemetry signal by generating a telemetry magnetic field, and a telemetry flux guide positioned between the induction coil and the circuit board. The telemetry flux guide is configured to direct magnetic flux of the telemetry magnetic field away from the circuit board.
