Claim:
1. A waterproof piezoelectric ceramic speaker, comprising: a ceramic composite including a ceramic plate and a driving electrode assembly arranged on a lateral side of the ceramic plate and supplying a driving voltage to the ceramic plate to generate vibration for the ceramic plate, the ceramic plate including a first conductive region and a second conductive region arranged in a same plane of the ceramic plate to receive the driving voltage, the driving electrode assembly including a first electric wire and a second electric wire which are respectively connected with the first conductive region and the second conductive region; and a vibration membrane including a first vibration layer and a second vibration layer respectively adhered to two opposite surfaces of the ceramic composite, wherein the first vibration layer and the second vibration layer respectively have a resonance member adhered to the ceramic plate and resonating with the ceramic plate synchronously, a waterproof member extending from a perimeter of the resonance member to seal the first electric wire and the second electric wire, and a bonding member extending from the perimeter of the resonance member and connecting with the waterproof member to seal the resonance member.
