Smartphone Vibration: Whenever you receive a call, receive a message notification or type on the keyboard, your smartphone vibrates slightly. This small vibration may seem simple but there is a very interesting technology behind it. A special motor system installed inside the smartphone produces this vibration which works to convey information through touch instead of sound.
What is vibration motor?
A small electric motor is installed in the smartphone to generate vibration. ERM (Eccentric Rotating Mass) motor was mainly used in early phones. In this, a round metal piece is connected to the motor in an unbalanced manner. As the motor rotates, that imbalance creates vibration and the phone starts vibrating. This technology is simple and cheap, hence it has been used for a long time.
LRA and the new world of haptic feedback
The use of LRA (Linear Resonant Actuator) technology has now increased in modern smartphones. It gives more accurate and faster response than traditional motor. It consists of a magnetic coil and spring mechanism that moves back and forth in a very controlled manner. For this reason, the vibration found in the new phone feels more smooth and premium. This is called haptic feedback which gives the user a physical button-like experience by giving a slight shock on touch.
How does the software control vibration?
Vibration is not just a matter of hardware but software also plays an important role in it. The phone’s operating system sets different patterns for different notifications. Like long vibrations for calls, short vibrations for messages or different feedback while playing games. This is why the feel of every alert is different.
Why is this technology necessary?
Vibration technology is important not only for silent mode but also for accessibility. This becomes an important hint for users with hearing problems. Apart from this, haptic technology also contributes a lot in providing better experience during gaming and typing.
Today’s smartphone is not limited to just voice and screen. Technology like vibration makes it more interactive and smart. Next time your phone vibrates, understand that a very sophisticated and advanced technical system is working behind it.
