MICROPHONE CONFIGURATION AND CALIBRATION VIA SUPPLY INTERFACE

摘要

A microphone or a microphone sensor system operates with a sensor interface that receives a supply voltage at a supply terminal. The sensor interface detects a command at the supply terminal based on a change in the supply voltage and communicates the command or data related to the command to a component of the sensor system. The supply terminal is a bidirectional terminal that further communicates data related to the sensor system via the supply terminal.

1. A microphone system comprising:
a sensor component configured to detect an audio signal based on an electrical signal generated from a membrane change; a data path component configured to process the electrical signal from the sensor component to generate an output signal at an output terminal; and an interface component comprising a supply terminal, wherein the supply terminal is configured to concurrently receive a supply signal from a power source and to receive, or transmit, one or more data commands to communicate one or more parameters related to the sensor component or the data path component.
