Vibrator (mechanical)

Typically, they are components of larger products such as smartphones, pagers, or video game controllers with a "rumble" feature.

Many older, non-electronic buzzers and doorbells contain a component that vibrates for the purpose of producing a sound.

Aircraft stick shakers use a vibrating mechanism attached to the pilots' control yokes to provide a tactile warning of an impending aerodynamic stall.

Vibration is often used to position small components so that they can be gripped mechanically by automated equipment as required for assembly etc.

An internal concrete vibrator is a steel cylinder about the size of the handle of a baseball bat, with a hose or electrical cord attached to one end.

In all three of these applications, the part under test will typically be instrumented with one or more accelerometers to measure component response to the vibration input.

A synthesized shock pulse is a short duration high level vibration calculated as a sum of many half-sine waves covering a range of frequencies.

Vibrating tables can also be used in the packaging process in material handling industries to shake or settle a container so it can hold more product.
