摘要

Improvements in the assembly of piezoelectric elements, in transducers, characterized by comprising the realization, in the bottom of the container box of the apparatus to which they are incorporated, of three small centering cavities, established in triangular arrangement and with suitable location, which are prevented symmetrically equidistant and officiate alveoli for reception and placement of the piezoelectric element, which is determined by a knt glass plate in square shape and adhered to a metal plate, preferably made of aluminum and with the same proportions as the glass, with which it forms a body, having been provided on the underside of this plate, that is, on the opposite side to the one that joins the glass, up to three semi-spherical projections in exact correspondence with other so many of their vertices and with a diameter slightly surpassing that of the alveoli practiced in the bottom of the box.
