摘要 |
The invention relates to a transducer plate, in particular for piezo-electric telephone receivers, with a piezo-ceramic element (6) provided with electrodes (2, 3) on both sides. The object of the invention is to compensate for the temperature dependence normally present in thicker ceramic elements. This object is achieved in that a piezo-ceramic element (6, 7) provided with electrodes (2, 3, 4, 5) on both sides is fitted in interlocking fashion on both sides of the transducer plate (1), and both piezo-ceramic elements are electrically connected in parallel. For use in telephone receivers in telephone systems. <IMAGE>
