In this embodiment, the piezoelectric portion 1420 includes a piezoelectric ceramic 1422, a carbon rod 1424, and a first circuit board 1426. By utilizing the piezoelectric effect of the piezoelectric ceramic 1422, when the first circuit board 1426 provides a voltage to the piezoelectric ceramic 1422, the piezoelectric ceramic 1422 can deform under the driving of electric power.
