永久性压电陶瓷晶片换能器
摘要：
一种永久性压电陶瓷晶片换能器，属于压电器件技术领域。本实用新型是由压电陶瓷晶片1、圆柱壳体2及其底板3、隔仓板4、二个金属环5、电解液6、导线7构成。本实用新型是以电解液6作为压电导瓷晶片换能器的电极，不存在压电导瓷晶片1两极面的金属电极腐蚀剥落问题，保证了压电陶瓷晶片1的永久性使用。本实用新型结构简单，构思新颖，安全可靠，寿命永久，成本低廉，是一种较为理想的压电陶瓷晶片换能器。
摘要（英）：

The utility model relates to a permanent piezoelectric ceramic crystal chip transducer, belonging to the technical field of piezoelectric devices, and composed of a piezoelectric ceramic chip 1, a cylindrical shell 2, a bottom plate 3, a chambers dividing plate 4, two metal rings 5, electrolyte 6, and a conductor wire 7. The utility model uses the electrolyte 6 as the electrode of the piezoelectric ceramic crystal chip transducer, no corrosion and exfoliation problems of the metal electrode at the two pole faces of the piezoelectric ceramic chip 1 is existed, and the permanent use of the piezoelectric ceramic chip 1 is ensured. The utility model has the advantages of simple structure, high safety, permanent service life, and low cost. The utility model is an ideal piezoelectric ceramic chip transducer.
