摘要： Electromechanical vibration transducers or pick-ups of this kind are manufactured from a single beam of ceramic material having at least one flat face provided with a deep slot at about its middle, separating it into two portions. This slot is being bridged by means of a transistor-type electromechanical transducer whose extremities are respectively fixed to the flat faces of the first and the second beam portions, one of which is mounted in a damping block and the second of which carries a pick-up stylus. After the mounting of the transistor and the stylus, the assembly is inserted into a protective housing from which only the stylus protrudes through an opening and the two beam portions are completely separated by cutting through the base of the slot, so as to become interconnected solely by means of the transistor substrate. The means preferably used for this cutting operation is a laser beam made to pass through the protective housing.
