Abstract
An acoustic transducer has a substrate having a cavity, a vibrating electrode plate disposed above the substrate and having a void portion that allows pressure to escape, a fixed electrode plate disposed above the substrate opposite the vibrating electrode plate, a plurality of sensing portions configured by the vibrating electrode plate and the fixed electrode plate, at least one of the vibrating electrode plate and the fixed electrode plate being divided into a plurality of regions, and a sensing portion being configured by the vibrating electrode plate and the fixed electrode plate in each of the divided regions, and a leak pressure regulation portion that hinders leakage of air pressure passing through the void portion when the vibrating electrode plate is not undergoing deformation.
