摘要： A microphone includes a base, a micro electro mechanical system (MEMS) device disposed on the base, and a front end processing apparatus disposed on the base and coupled to the MEMS device, the front end processing apparatus being configured to convert analog signals received from the MEMS device into digital signals. The microphone also includes a DSP apparatus, the DSP apparatus being a digital programmed device with a computer memory, the DSP apparatus configured to process the digital signals received from the front end processing apparatus. The MEMS device, the front end processing apparatus, and DSP apparatus are enclosed within a single microphone enclosure or assembly. During operation the DSP apparatus generates DSP noise. The DSP apparatus includes a noise reduction structure that substantially prevents the DSP noise from reaching or interfering with the operation of the MEMS device or the front end processing apparatus.

摘要： The present disclosure relates to an integrated circuit connectable to a microelectromechanical system (MEMS) transducer. The MEMS transducer is configured to generate a transducer audio signal in response to sound. The integrated circuit comprises a digital scrambling circuit coupled to a data communication interface. The digital scrambling circuit is configured to convert a digital audio stream, representative of the transducer audio signal, into a corresponding scrambled data stream. The integrated circuit additionally comprises a data bus interface coupled to the digital scrambling circuit and configured to output the scrambled data stream.
