that we use every day smartphone vibrations, It alerts us to 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 in our phones.

These engines are divided into two main types: Axial Rotary Motor (ERM) and linear resonant actuator (LRA). Vibration generation, simple or complex, starts with a touch or a signal from software or hardware.

The electrical signal coming from the equipment causes vibrations Creating haptic feedback goes to the special microprocessor.

This microprocessor determines the type of vibration needed. However, since it does not have the power needed to create vibrations, it does its job. Haptic handover to the driver.

The haptic driver sends rapidly varying current to a haptic actuator/motor, guided by the control signal from the processor.

This stream engine produces vibrations causes. This changes a simple touch or ring signal into vibrations.

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 required vibrations depending on the situation.
