Abstract: The present invention discloses a piezoelectric loudspeaker. The piezoelectric loudspeaker comprises a sound producing plate, a resonant sound-box, a surround and a reflective sound-box. The sound producing plate comprises a piezoelectric ceramic element. The resonant sound-box includes a first opening comprising a first carrying part. The sound producing plate is disposed on the first carrying part. A cavity resonator is formed between the sound producing plate and the resonant sound-box. The surround is disposed between the first carrying part and the sound producing plate. The reflective sound-box includes a second opening and a reflective output opening. The second opening comprises a second carrying part. The resonant sound-box is disposed on the second carrying part. A reflective cavity body is formed between the resonant sound-box and the reflective sound-box, and the reflective cavity body is connected the reflective output opening.
