摘要
The invention relates to a transducer apparatus to provide audio sensing with high noise immunity in an acoustically-noisy environment. The invention replaces the prior-art acoustic microphone with a non-acoustic sensor to sense free-field and/or surface vibrations or movement that resemble or arising from the voice of the user. The non-acoustic sensor includes an accelerometer, shock sensor, gyroscope, vibration microphone, or vibration sensor. There are several adaptions and embodiments of the invention including improving the polar directivity of the non-acoustic sensors and application of a multiplicity of non-acoustic sensors and acoustic microphones.
