A sound producing device is provided. The sound producing device comprises a substrate; and a membrane pair, disposed on the substrate, comprising a first membrane and a second membrane; wherein when a driving voltage is applied on the membrane pair, the first membrane and the second membrane deform toward each other, such that air between the first membrane and the second membrane is squeezed outward and an air pulse is generated toward a direction away from the substrate.
