Abstract
Provided is an acoustic transducer including: a semiconductor substrate; a vibrating membrane, provided above the semiconductor substrate, including a vibrating electrode; and a fixed membrane, provided above the semiconductor substrate, including a fixed electrode, the acoustic transducer detecting a sound wave according to changes in capacitances between the vibrating electrode and the fixed electrode, converting the sound wave into electrical signals, and outputting the electrical signals. At least one of the vibrating electrode and the fixed electrode is divided into a plurality of divided electrodes, and the plurality of divided electrodes outputting the electrical signals.
