Abstract
A micro-size electronic shotgun microphone, which is used for receive a sound source from a direction, includes a sound receiving portion, an A/D converter and a digital signal processor. The sound receiving portion includes a first sound receiving unit, a second sound receiving unit with a first distance away from the first sound receiving unit and a third sound receiving unit with a second distance away from the second sound receiving unit. The first distance is longer than the second distance. The first sound receiving unit, the second sound receiving unit and the third sound receiving unit output an analog signal respectively after receiving the sound source. The analog signal is processed by the A/D converter and the digital signal processor to convert into a directional digital signal with a maximum receiving frequency so as to improve the problem of grating lobes and spatial aliasing.
