  • a body with a cavity therein and a plurality of grooves spaced along one dimension of said body and extending between the cavity and a surface of said body;

    substrate, the plurality of grooves being spaced along the length of said substrate with each groove extending between the trough and another surface of said substrate;

    a sheet of non-conductive material against the one surface of the substrate, said sheet having plurality of electrodes arranged so that ends of two different electrodes communicate with each groove, wherein applying a voltage selectively between pairs of the plurality of electrodes produces an arc in each of said grooves, and having a plurality of electrical buses to which the plurality of electrodes connect; and

    a diaphragm against said sheet and covering the trough and the plurality of grooves, said diaphragm being formed of a resilient material that dampens a pressure wave produced within a groove when an arc occurs between electrodes within that groove.
