  • FT-21.5T-4.0ASL1
  • FBelec has developed a new type of double-sided piezo element, including piezoelectric vibrating plate and sound film. A first power lead is welded on the metal plate part of the piezoelectric vibrating plate, and a short circuit is provided on one side of the piezoelectric vibrating plate. A copper sheet, the short-circuiting copper sheet includes a connecting portion provided with a mounting hole, a first crimping portion and a second crimping portion extending outward from one side of the connecting portion, and the first crimping portion and the second crimping portion The outer ends of the crimping part are respectively welded on the silver electrodes of the piezoelectric ceramic plate part on the corresponding side of the piezoelectric vibration plate, and the second power lead is welded on the connecting part. It solves the problem of "reducing the double-sided buzzing" It has a series of advantages such as low product failure rate, good product structure stability and long product service life.Best Piezo Round Bimorph in China.
