Vibration alert
Under a vibrator is defined as a signal transmitter which by vibration signals the occurrence of an event. The user typically perceives this through the skin by wearing the device close to the body.
Application and function
It is mainly used on cell phones for incoming calls, SMS messages or other notifications. Instead of an acoustic ringtone or in addition to it, more or less silent vibrations are triggered. This is particularly useful when disturbances to people present due to noise are to be avoided or an acoustic signal could easily be overheard due to the surrounding noise. Another application in mobile phones is haptic feedback on touchscreens , with the vibration serving as feedback for a successful touch.
This signal transmitter is usually already built into modern cell phones. In older generations of devices, it could partially be retrofitted with an appropriately equipped battery.
In cell phones, the vibrations are typically generated by a small motor that carries an imbalance . Due to its inertia, the imbalance ensures that the housing vibrates. In some mobile phones, the loudspeaker or earpiece is used as a vibration generator by operating it at low frequencies. The loudspeaker membrane is thus set into mechanical vibrations and represents the counterweight to the housing, which is caused to vibrate by the inertia of the membrane.
The mobile phone manufacturer Nokia has also patented a concept with which tattoos can be made to vibrate with incoming calls. Magnetic waves enable the tattoo to communicate with the smartphone . Even an individual programming regarding the type of vibration should be possible depending on the caller. However, the technology does not work with normal traditional tattoos. The ink sprayed under the skin must contain iron or iron oxide so that it can be activated with the help of the magnetic waves.
A wide variety of devices with vibration alarms are frequently used by people with hearing impairments (such as baby monitors, alarm clocks, etc.). Another area of application are wristwatches, which are used as a reminder to take medication or for enuresis diurna.
Vibration alarm systems for vehicle construction are currently in the test stage . These systems should help the driver to save fuel by vibrating the accelerator pedal . Electronics use information from an extended satellite navigation system and a radar system to determine the current traffic situation and derive an economically sensible speed from this. If the current speed is above the speed determined in this way, the driver is made aware of this by a vibration in the accelerator pedal.
