Abstract
A microphone system includes: a microphone including a microphone output terminal and a microphone GND terminal, the microphone being configured to output, as an input sound signal, a voltage signal exhibiting a change in voltage between the microphone output terminal and the microphone GND terminal depending on an input sound; an A/D converting unit mounted on a first circuit board and configured to perform digital conversion on the input sound signal that is input; and a power supply circuit mounted on a second circuit board connected to the first circuit board via a pair of power supply lines, and configured to feed DC power to the A/D converting unit via the pair of power supply lines. The microphone outputs the input sound signal to the A/D converting unit via a pair of first signal lines different from the pair of power supply lines.
