Abstract
A dual diaphragm microphone can be used to reduce or eliminate a component of the output signal due to acceleration of the microphone. The dual diaphragm microphone can include a first sound-detecting component including a first diaphragm spaced apart from a first electrode and configured to generate a first signal and a second sound-detecting component including a second diaphragm spaced apart from a second electrode and configured to generate a second signal. The first sound-detecting component and the second sound-detecting component are oriented in opposite directions and include electronic circuitry configured to sum the first and second output signals to generate a combined output signal substantially unaffected by acceleration of the microphone.
