Abstract
Improved piezoelectric device, of the type comprising a quartz crystal or the like, disposed between a pair of cores that occupy their respective ends and in one of which a movable piece, floating due to being arranged between two opposing springs, can strike when it is released the compression of one of them; characterized in that the assembly is organized on a tubular casing, with perimetrally inwardly diverted edges, in which, at one of its ends and protruding partially towards the outside, a dielectric part having a threaded strip for receiving a nut is adapted. Of fixation and is internally hollow, having inside a step that prevents the exit and serves as limiting seat to one of the cores, which is provided with an axial rod, telescopic with respect to the outer end of said dielectric piece.
