piezoelectric vibrator

piezoelectric vibrator

[pē¦ā·zō·ə′lek·trik ′vī‚brād·ər]
(solid-state physics)
An element cut from piezoelectric material, usually in the form of a plate, bar, or ring, with electrodes attached to or supported near the element to excite one of its resonant frequencies.

Piezoelectric vibrator 2 is pressed to the upper end of the peg with pressing force F1 and excites peg in axial direction.
Pressing force of piezoelectric vibrator to the peg was gradually increased every 14 N and corresponding measurements of vibration magnitudes on all three axes were taken.
Such character of amplitude increment related with contact area changes between peg and piezoelectric vibrator.
It is necessary that the entire rear surface of the peg is in contact with piezoelectric vibrator, so the maximum vibration energy passes from vibrator to peg.
It involves a hermetically sealed conventional microphone, battery, electronic unit, and piezoelectric vibrator of the ossicular chain.
The peg is fixed in a gripper and the piezoelectric vibrator is pressed to the upper end of the peg.
Low frequency signal generator 3 provides signal to the piezoelectric vibrator.
Piezoelectric vibrator 5 is implemented in a housing 6.
As the piezoelectric vibrator lean to the peg, further torque increment sets pressing force for the piezoelectric vibrator to the peg.
Piezoelectric vibrator 11 is attached to the end of the shaft which excites its longitudinal vibrations.
Two piezoelectric vibrators 18 are attached to the different parts of the platform and excite the elastic vibrations.
Other topics explored include power spectral density modeling of torsional dynamic wind loads on tall buildings, and energy harvesting behaviors of different shapes of piezoelectric vibrators.
