What does vibrating mean?
Vibrating is the present-participle form of vibrate and also functions as an adjective. It describes a body, surface, voice, or device that moves in rapid, repeated oscillations, producing a fine tremor or a perceptible hum. As a verb, it can describe both the source of that movement and its transmission through another material. The word is neutral in register and common in British and American English, but its implication of repetition and speed makes it more precise than shaking, which may describe one abrupt movement. Vibrating also suggests that something is under tension or intensely active, especially when it describes a voice. It is therefore useful in both literal accounts of physical motion and figurative descriptions of sound, force, and energy, though it should not be confused with vibrant, which means lively rather than literally oscillating.
To move in rapid, repeated oscillations; to shake, tremble, or quiver slightly.
"The blade vibrates slightly when the machine reaches full speed."
As a third-person singular form, it normally takes -s; as a present participle, it may accompany an auxiliary verb or function adjectivally.
Causing, undergoing, or characterized by rapid, repeated movement or oscillation.
"A vibrating phone lit up beside the sleeping child."
This participial use is especially common in technical, mechanical, and electronic contexts.
Vibrating comes from a Latin verb meaning "to shake or agitate," so its roots are literally tied to movement.

Where does vibrating come from?
Vibrating comes from vibrate, which entered English from French in the early 17th century and ultimately derives from Latin vibrare, "to shake or agitate." Latin vibrare was formed from vibere, "to move or sway," a root also reflected in forms such as vibration and vibrant. The Italian musical term vibrato and the English derivatives vibratory and vibration likewise continue this Latin family.
How vibrating is actually used
Neutral in register and common in both British and American English. The word usually suggests sustained, repeated motion rather than a single abrupt movement; applied to a voice, it can indicate emotional intensity, force, or tension.
