Abstract
Methods and apparatuses for reduced microphone handling noise are disclosed. In one example, a microphone system includes a microphone to output a microphone output signal and a sensor adapted to output a sensor signal indicating whether the sensor is in proximity to or touching a user finger. A processor is adapted to process the microphone output signal using touch mode signal processing responsive to a determination the sensor is in proximity to or touching the user finger.
Claims21
A microphone system comprising:
- a microphone element to output a microphone output signal;
- a touch sensor disposed on or within proximity of an outward facing surface of a microphone system housing;
- a touch sensor circuit coupled to the touch sensor configured to receive signals from the touch sensor and determine whether the touch sensor is touching a user skin surface;
- and
- a processor adapted to process the microphone output signal using a modified signal processing responsive to a determination the touch sensor is touching a user skin.
A method for processing a microphone signal comprising:
- receiving a microphone signal output from a microphone element;
- receiving a sensor output signal indicating a first condition where a user skin is not in proximity to or in contact with a sensor or indicating a second condition where the user skin is in proximity to or in contact with the sensor;
- and
- processing the microphone signal responsive to the sensor output signal.
A microphone system comprising:
- a microphone to output a microphone output signal;
- a sensor adapted to output a sensor signal indicating whether the sensor is in proximity to or touching a user finger;
- and
- a processor adapted to process the microphone output signal using a touch mode signal processing responsive to a determination the sensor is in proximity to or touching the user finger.
A method for processing a microphone signal comprising:
- receiving a microphone signal output from a microphone element;
- processing the microphone signal using a first signal processing method;
- receiving a sensor output signal indicating a user finger in proximity to or in contact with a sensor;
- processing the microphone signal using a second signal processing method responsive to receiving the sensor output signal indicating the user finger in proximity to or in contact with the sensor;
- receiving an updated sensor output signal indicating removal of the user finger from contact with the sensor;
- and
- resuming processing the microphone signal using the first signal processing method.
