電形送受話器。 It comprises a piezoelectric diaphragm having a ceramic piezoelectric material, and a back plate having a pair of terminal pieces disposed on the back side of the diaphragm for electrically connecting the ceramic piezoelectric material to the outside. The outer end of the lead piece inserted through the provided lead hole is electrically connected to one side of one terminal on the back side of the back plate, and the inner end is soldered to the electrode part of the ceramic piezoelectric body. In a piezoelectric handset that is electrically connected by mounting, the back plate is integrally formed of a synthetic resin material, and the lead hole is formed with a large opening size. A piezoelectric handset characterized in that at least a pair of elastic pieces protrudes from the inner wall of the lead hole so as to close the opening except for the lead piece insertion part.
