As a core component of the water sound transducer, the piezoelectric ceramic ring is responsible for the mutual conversion of electrical energy and mechanical energy, and realizes the emission and reception of sound waves. The cleaning of the piezoelectric ceramic ring is an important process link in the bonding and assembly process of the water sound transducer. Thoroughly cleaning the oxide, oil stains and other impurities on the surface of the silver-plated layer (electrode) of the ceramic ring is a prerequisite for the excellent electrical conductivity and bonding strength of the assembled transducer ceramic ring, and is also a key factor to ensure the ideal acoustic performance and working efficiency of the water sound transducer.
