Kinetic event detection in microphones

摘要

In one implementation, the output of a microphone is modified based on movement. A circuit or other controller is in communication with a microphone that generates an electrical signal based on sounds waves and a motion sensor. The motion sensor may be coupled to the microphone, coupled to a device including the microphone, or coupled to an object in the vicinity of the microphone. The controller is configured to receive the electrical signal from the microphone and motion data from the motion sensor. The controller is configured to perform a comparison of the motion data to a threshold level and adjust the electrical signal in response to the comparison of the motion data to a threshold acceleration level.

1. A method comprising:
converting sound to an output signal from a microphone of a telephone; receiving acceleration data based on motion of the telephone and the microphone; performing a comparison of the acceleration data to a threshold acceleration level; and adjusting the output signal of the telephone in response to the comparison of the acceleration data to a threshold acceleration level, wherein adjusting includes reducing an amplitude of the output signal by an amount proportional to a difference between the threshold acceleration level and the acceleration data.
