Magnetic device and vibratory transducer with such a magnetic device

The magnetic device comprises providing a magnetic field, in particular rod-shaped, permanent magnet (51a), a holding device rigidly connected to the permanent magnet (51c) with a side facing the permanent magnet retaining head (51c ') for supporting the permanent magnet and a fixed to the holding head retaining bolt (51c' ' ) and a magnetic cup (51b) having a cup base (51b ') and a line extending from the cup bottom of the cup wall (51b' '). The retaining head of the retaining device (51 #) was added at least partly by a recess provided in the cup base implementation, so that an outer contact surface of the holding head (C) and an inner contact surface of the passage (B) each other to form a frictional connection between the magnet cup and retaining means touch. The magnetic device is provided in particular for use as the vibration transducer and / or for use in a vibratory transducer.
