Abstract
A microphone device includes a housing, a microphone, a phone microphone, an analog wire, a conversion unit, and a processor. The housing has an opening portion and a horn including a horn opening portion and a horn tube extending from the horn opening portion. The microphone converts a sound that has propagated through the opening portion into an analog signal. The horn microphone converts a sound that has propagated through the horn into an analog signal. The analog wire outputs the analog signal from the horn microphone. The conversion unit acquires the analog signal from the microphone, acquires the analog signal from the horn microphone via a wire different from the analog wire, and converts the analog signal from the microphone and the analog signal from the horn microphone into digital signals. The processor performs digital signal processing on the digital signals converted by the conversion unit.
