Good vibrations: how vibrating devices can help wearers …
The system will take a digital audio signal (speech), slice it up, and analyze each increment to determine whether or not the vocal folds are vibrating. If it seems likely that they are, then the vibrator activates, with the intensity corresponding to the loudness of the source. We explored wearing the device in various locations on your body ...

A good electric toothbrush: Rotating vs Sonic – Health Melody
The brush head moves side-to-side vibrating at a super high speed to scrub the bristles against the teeth. Such a high speed vibration generates a powerful pulsating action to agitate the oral fluid and produce the non contact cleaning effect (as in case of rotating-oscillating-pulsating toothbrushes). The brush head in vibrating toothbrushes ...

Circular vibrating screens
Working principle: Circular vibrating screens operate using indirect excitation of the screen mesh. The entire screen frame is driven by unbalance masses, which produce a circular vibrating motion. Another key feature: The directionless vibrations of the circular vibrating system have a steep launch angle and the screen area must be further ...

Vibrational Modes of a Circular Membrane
The frequency of the (1,1) mode is 1.593 times the frequency of the (0,1) mode. When vibrating in the (1,1) mode a circular membrane acts much like a dipole source; instead of pushing air away from the membrane like the (0,1) mode does, in the (1,1) mode one half of the membrane pushes air up while the other half sucks air down resulting in air ...

25 Vibrations and Waves 25.1 Vibration of a Pendulum
25.2 Wave Description. If the frequency of a vibrating object is known, its period can be calculated, and vice versa. Suppose, for example, that a pendulum makes two vibrations in one second. Its frequency is 2 Hz. The time needed to complete one vibration—that is, the period of vibration—is 1/2 second.
