An acoustic transducer comprises a substrate, a membrane configured to move relative to the substrate, a number of supports configured to suspend the membrane over the substrate, a first group of projections extending from the membrane, and a second group of projections extending from the substrate, the second group of projections being interweaved with and movable relative to the first group of projections, wherein each projection of one group of the first group of projections and the second group of projections is composed of a first conductive layer, a second conductive layer and a dielectric layer between the first conductive layer and the second conductive layer, and each projection of the other one group of the first group of projections and the second group of projections is composed of a third conductive layer.
