METHOD FOR REDUCING PHASE VARIATION OF SIGNALS GENERATED BY ELECTRET CONDENSER MICROPHONES |
摘要 |
The invention provides a method for reducing phase variation of a signal generated by an electret condenser microphone. An error of a capacitance of the electret condenser microphone is reduced. An impedance of the electret condenser microphone is increased. A shunt resistance is added to the electret condenser microphone. A -3 dB cut-off frequency of the electret condenser microphone is lowered.
