The band splitter receives a first audio signal and splits the first audio signal into band signals. The gain producers gain the band signals respectively. The adder receives the gained band signals to generate a second audio signal. The piezoelectric speaker outputs a sound according to the second audio signal. The sound compensator analyzes a sound pressure level of the sound to generate a control signal. The gain-adjusting device adjusts the gains of the gain producers according to the control signal."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Piezoelectric speaker driving system and method thereof","description":"A piezoelectric speaker driving system includes a band splitter, a plurality of gain producers, an adder, a piezoelectric speaker, a sound compensator and a gain-adjusting device.
