| There is provided an electro-mechanical vibration transducer which effectively produces a heavy low vibration. Such a structure is adopted that a yoke is supported in a case of the electro-mechanical vibration transducer by dampers, so that the case and the yoke are relatively displaceable. For the purpose of reducing the load applied to the dampers through vibration at the time of transportation of the transducer, a lock key having a projecting portion is installed to a bottom portion of the case, and the projecting portion is engaged between the yoke and the frame, so that a relative displacement of the yoke is prevented. By the installation of this lock key, defect due to vibration at the time of transportation of products can be prevented from occurring in the products, and the dampers having excellent vibration efficiency can be used, so that a heavy low sound vibration can be sufficiently obtained. | ||||||

| PROBLEM TO BE SOLVED: To provide an electromechanical vibration transducer by which a heavy and low sound vibration is efficiently generated. SOLUTION: A york 110 is supported by dampers 106 and 107 in a case 101 of the electromechanical vibration transducer and can be displaced relatively to the case 101. A lock key 201 having a projecting part 202 is mounted on the bottom part of the case 101 in order to relieve burden on the dumper by the vibration in case of carrying the converter, the projecting part 202 is engaged with a part between the york 110 and a frame 103 and the relative displacement of the york 110 is prevented. The mounting of the lock key enables eliminating product defect owing to the vibration in case of carrying and also the heavy and low sound vibration is sufficiently obtained since the dampers 106 and 107 with excellent vibration efficiency are used.
