The embodiment of the utility model discloses a sound production assembly and a piezoelectric loudspeaker. The sound production assembly comprises at least one layer of conductive supporting part and a plurality of layers of piezoelectric motor units. Each piezoelectric motor unit comprises two layers of conductive films and a piezoelectric film arranged between the two layers of conductive films. At least one notch is formed in each layer of conductive supporting part, the positions of the notches are matched with the side edges of the piezoelectric motor units, and a layer of conductive part is connected between every two adjacent layers of piezoelectric motor units so that the sounding assembly can achieve side sounding through the notches. Therefore, through the arrangement of the conductive supporting part with the notch, the notch faces the side edge of the piezoelectric motor unit, and the design requirement of side sound emission of the piezoelectric loudspeaker is met. 本实用新型实施例公开了一种发声组件和压电扬声器，该发声组件包括
