  • Microphone device with two sounds receiving modules and sound collecting trough
    Patent number: 10026391
    Abstract: A microphone device including a first sound receiving module, a second sound receiving module and a sound collecting trough is provided. The first sound receiving module receives a sound signal to output a first electronic signal. The second sound receiving module receives the sound signal to output a second electronic signal. The first sound receiving module is coupled to 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. A distance between the first sound receiving module and the sound collecting trough is smaller than a distance between the second sound receiving module and the sound collecting trough, and another sound signal is transferred to the first sound receiving module through the sound collecting trough.
