Abstract:
A sound pressure gradient microphone includes: a first non-directional microphone; a second non-directional microphone; a delay device that receives an output of the second non-directional microphone; and a subtractor that receives an output of the first non-directional microphone and an output of the delay device. The subtractor outputs a difference between the output of the first non-directional microphone and the output of the delay device. A phase of the first non-directional microphone is ahead of a phase of the second non-directional microphone.

Claim (Index 2):
A sound pressure gradient microphone comprising:\n a first non-directional microphone; a second non-directional microphone; a first high-pass filter that receives an output of the first non-directional microphone; a second high-pass filter that receives an output of the second non-directional microphone; a delay device that receives an output of the second high-pass filter; and a subtractor that receives an output of the first high-pass filter and an output of the delay device, and outputs a difference between the output of the first high-pass filter and the output of the delay device, wherein the first high-pass filter includes a first capacitor which is disposed between the first non-directional microphone and the subtractor, and is connected in series to the first non-directional microphone and the subtractor, the second high-pass filter includes a second capacitor which is disposed between the second non-directional microphone and the delay device, and is connected in series to the second non-directional microphone and the delay device, and a capacitance value of the first capacitor is smaller than a capacitance value of the second capacitor so as to achieve a state where a phase of a signal output from the first high-pass filter is ahead of a phase of a signal output from the second high-pass filter.
