A means for being electrically connected to an electrode of a piezo-electric plate is adapted for connecting the piezo-electric plate to a circuit board disposed under the piezo-electric plate. The piezo-electric plate and the circuit board are respectively provided with a first electrode and a second electrode corresponding to the first electrode. The means includes a conductive element and an elastic element. The conductive element includes at least two connecting surfaces electrically connected to each other and respectively electrically connected to the first electrode and the second electrode. The elastic element is joined with the conductive element and located between the piezo-electric plate and the circuit board.
