What is the technology behind those vibrations we feel when we touch our phones or receive a call?
that we use every day smartphone vibrations, It notifies us of an incoming phone call or allows us to receive other notifications in silent mode.
Well, these vibrations How is it formed?
The source of vibrations are the small motors inside our phones.
These engines are divided into two main types: Axial rotating motor (ERM) and linear resonance actuator (LRA). The generation of vibrations, whether simple or complex, begins with a touch or a signal from software or hardware.
The electrical signal coming from the equipment to create vibrations Creating haptic feedback goes to the dedicated microprocessor.
This microprocessor determines the type of vibration needed. However, since it does not have the power needed to create vibrations, it does the job. Haptic hands over to the driver.
The haptic driver sends rapidly varying current to a haptic actuator/motor, guided by the control signal from the processor.
This current engine produces vibrations causes. As a result, a simple touch or call signal turns into a vibration.
We have presets on our phones for different situations. programmed vibration libraries These vibrations can be detected or programmed to create unique tactile sensations. The haptic microprocessor determines the necessary vibrations depending on the situation.
