Vibration derives from vibratĭo, a Latin word. It is about the process and consequence of vibrating: making something move, wobble, shake or tremble. The concept can be used in different ways depending on the context.
In the field of physics, a vibration is produced when elastic waves propagate causing tensions and deformations in a continuous medium. Vibrations can be said to involve repeated motion around an equilibrium position (which is the resulting position when the force is zero). It should be noted that elastic waves are stress changes that diffuse through an elastic medium. When an earthquake occurs, a vibration of the surface is registered since there are elastic waves (in this case called seismic waves) that propagate.
Earthquakes, also known as earthquakes, are phenomena characterized by a strong shaking of the earth’s crust that usually lasts a short time, although in some cases it leaves terrible consequences, such as the destruction of towns and cities, as well as a large number of deaths and injuries. . In music, the concept of vibration is fundamental, since it is thanks to this phenomenon of physics that most instruments can emit sounds; in fact, even those that do not seem to depend on it, such as those of the wind, also take advantage of it to enrich the timbre of sounds every time the air comes into contact with their walls. Like many other species of animals, the human being has the so-called vocal cords, which are not actually cords per se, but a set of lips or membranous folds that, when vibrated, produce different sounds. Everything begins with inspiration, since the air is in charge of gently brushing the strands to generate that movement and maintain it for as long as necessary. The sound also causes certain parts of the bone, known as resonators, to vibrate, which function as natural amplifiers. A molecular vibration is one that affects the atoms of a molecule. Vibrations can be bending (which changes the angle between two bonds) or tension (generating a continuous change in the distance between atoms around the axis of the bond). The idea of electronic vibration, on the other hand, refers to the movement that electrons make when moving through conductors and components of a system where a potential difference is applied.
In everyday language, vibration is the unsteady movement that does something. A cell phone (mobile) in a vibrating state, to cite one case, is one that begins to move repeatedly when a call or message arrives. Video games are also related to this concept, since many of the current controls include motors that vibrate when the program demands it, to intensify situations within the game such as an accident, a blow or an explosion. The first company to massify these engines was Nintendo, when in 1997 it launched an accessory for its Nintendo 64 console called the Rumble Pak, which had to be inserted in the lower part of the remote control and required the use of two AAA batteries to work. It didn’t take long for other companies to copy the Japanese giant’s idea, and soon this feature became a key feature of video game controllers, so many young people don’t know that Nintendo released it. Currently, on the other hand, it is no longer necessary to use batteries if the control is connected by cable, since it receives its power directly from the console.
