Annotations languages:

The analysis of electric durability of designs of electro-acoustic devices are the important making modern electro-acoustic equipment which is carried out. Typical designs of cylindrical and rod piezoceramic electro-acoustic transducers are considered. It is shown by what elements of designs their electric durability is provided. Places of essentially non-uniform electric fields in the basic types of designs of piezoceramic electro-acoustic transducers are established. In them there can be electric breakdowns. It is shown, that all designs of electro-acoustic devices have identical places in which occurrence of electric breakdowns is possible. However working out of the unified design decisions concerning their electroisolation is possible only for electric inputs of designs of transducers.
