Waterproof piezoelectric ceramic speaker
A waterproof piezoelectric ceramic speaker includes a ceramic composite and a vibration membrane. The ceramic composite includes a ceramic plate and a driving electrode assembly arranged on the ceramic plate and supplying a driving voltage to the ceramic plate to generate vibration for the ceramic plate. The vibration membrane includes a first vibration layer and a second vibration layer respectively adhered to two opposite surfaces of the ceramic composite. 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 connecting with the resonance member to seal the driving electrode assembly, and a bonding member extending from a perimeter of the resonance member to seal the resonance member.
