Microphone manufacturing method, microphone, and control method
Abstract:
A method of manufacturing a microphone, a microphone, and a method of controlling the microphone are provided. The method includes forming a sound sensing module on a mainboard having a first sound aperture, to be connected with the first sound aperature and forming a cover having a second sound aperature that corresponds to the first sound aperature, mounted on the mainboard, and housing the sound sensing module. A first and second sound delay filters are formed in a space defined by the cover, to be connected with the second sound hole and thermal actuators are disposed at both sides of the first sound delay filter and move the first sound delay filter based on whether power is supplied. A semiconductor chip is electrically connected with the sound sensing module in the space and selectively operates the thermal actuators in response to signals from the sound sensing module.
