Abstract
Disclosed are a method of manufacturing a microphone, a microphone, and a control method thereof. The method includes forming a sound sensing module on a main substrate including a first sound aperture such that the sound sensing module is connected to the first sound aperture. The method further include forming a cover for receiving the sound sensing module formed therein with a second sound aperture corresponding to the first sound aperture on the main substrate. The method also includes forming a sound delay filter at a receiving space of the cover to be connected to the second sound aperture. The method also includes forming a semiconductor chip electrically connected to the sound sensing module at the receiving space, to selectively operate the sound delay filter according to a signal output from the sound sensing module.
