Abstract
A microphone device including a first sound receiving module and a second sound receiving module is provided. The first sound receiving module includes a first output terminal and receives a sound signal to output a first electronic signal through the first output terminal. The second sound receiving module, which disposed adjacent to the first sound receiving module to receive the sound signal, includes a second output terminal and outputs a second electronic signal through the second output terminal accordingly. The first output terminal of the first sound receiving module is coupled to the second output terminal of the second sound receiving module, and the phase of the first electronic signal and the phase of the second electronic signal are inverse to each other.
