Abstract

The utility model discloses a concave-convex corrugated double-sided buzzer, which comprises a ceramic plate, wherein an electrode plate is printed on the top of the ceramic plate, a copper sheet is bonded on the top of the electrode plate, auxiliary mechanisms are bonded on the left side and the right side of the surface of the ceramic plate, each auxiliary mechanism comprises a sector plate, a nylon rope and a copper pipe, the left side and the right side of the surface of the ceramic plate are bonded with sector plates, and nylon ropes are bonded on the top and the bottom of the inner wall of each sector plate. According to the utility model, through the arrangement of the auxiliary mechanism, the ceramic plate can be subjected to telescopic deformation under the influence of a voltage field, the ceramic plate deforms to drive the sector plate to vibrate integrally, and the sector plate depends on the fact that one end of the sector plate is provided with the nylon rope, the other end of the copper pipe is not provided with the nylon rope and the copper pipe to form a weight difference, so that the eccentric vibration amplitude of one end of the sector plate, which is overweight, is increased when the ceramic plate deforms, and therefore eccentric wheel type vibration is realized, and the problem that the vibration amplitude cannot be increased due to poor independent vibration effect of the ceramic plate is avoided.
