The utility model provides an adsorption type piezoelectric exciting vibrator and aims at solving the shortcomings of the existing exciting vibrator. The adsorption type piezoelectric exciting vibrator comprises a wiring terminal, a counter weight, a fastening screw, more than three annular piezoelectric ceramic pieces, a stainless steel tank, an energy gathering pin, a rubber sleeve, a base, an inner magnetic shielding ring, a magnet ring and an outer magnetic shielding ring. A circular groove is formed in one end of the counter weight; a threaded hole is formed in the center of the circular groove and connected with one end of the fastening screw. A wiring hole is formed in the counter weight and connected with the wiring terminal. The piezoelectric ceramic pieces sleeve the middle part of the fastening screw. The other end of the fastening screw is connected with the energy gathering pin. The rubber sleeve sleeves the energy gathering pin. The base sleeves the rubber sleeve. The counter weight is connected
