A vibrator is a mechanical device that is designed to generate vibrations. The vibration is often generated by an electric motor with an unbalanced weight (mass) on its driveshaft. If the motor is switched on, the rotating weight will resonate.
There are many different types of vibrator, including those in cellphones and pagers. There are also vibrating devices intended to touch the body (including insertion in a body cavity), thereby stimulating the nerves and giving a pleasurable and possibly erotic feeling.
Industrial uses of vibrators include: In construction industries, high-powered industrial vibrators are used to remove air bubbles from freshly poured concrete. There are also a number of different types of vibrators used in the construction industry to settle and compact soil. Another type of vibrator can be used to drive foundation piles into the ground. Used in emptying a hopper containing granular material such as corn or grain. The vibrations of the vibrator reduces friction during discharge and helps maintain a reliable flow of material. Small printing firms will use vibrator tables to square-up a pile of pages after they have been printed. In the aerospace and military electronics industries, engineers often test electronic circuit cards both individually and in their equipment boxes whilst mounted on a flat vibrating table. The table is driven from a large motor similar to a moving-coil loudspeaker. The frequency of vibration can be random, or specific frequencies can be used to detect and permit the assessment of resonances. As the mechanism for a conveyor belt. Basically the belt jerks down and then back whilst not in contact with the objects being moved. Then the belt rises to recontact the object and moves forward, advancing the object. This technique is most commonly used with small particles. A similar technique can be used to achieve a vertical conveyor system using a multitude of tiny suitably-shaped buckets. In mobile telephones, a vibrator is mechanical device that produces vibratory motion to notice a call, see vibrating alert.
