It includes a piezoelectric ceramic buzzer, terminals, a shielding layer, and a power signal line. The piezoelectric ceramic buzzer comprises a piezoelectric ceramic sheet and a substrate bonded together. The piezoelectric ceramic sheet is connected to the power signal line, which is also connected to the terminal. The shielding layer covers the power signal line and includes a guide wire and conductive tape. The guide wire is coiled around the power signal line.
