Abstract

The invention discloses a manufacturing method of a piezoelectric vibration generating set. The method comprises the steps that (1) piezoelectric component sub units are obtained in batches through laser welding, a piezoelectric plate and a free vibrator are mounted on each piezoelectric component sub unit to obtain a piezoelectric component; (2) a base of a hollow structure is provided, and the hollow structure of the base forms a containing cavity; (3) at least two piezoelectric components are provided and mounted on the base in parallel, and the free vibrators of the piezoelectric components are contained in the containing cavity; (4) bottom caps are provided and arranged at the two ends of the base in a covering mode correspondingly; (5) at least two conductive welding pins are provided to be connected with the piezoelectric components and penetrate through one bottom cap to form a conductive electrode. Due to the fact that laser welding is adopted to obtain the piezoelectric component sub units in batches, in the assembling and producing processes, accurate alignment is facilitated, assembling accuracy is improved, production efficiency is improved greatly through batch production, and therefore production cost is lowered. In addition, the invention further discloses the piezoelectric vibration generating set.
