The main function of a smartphone is to provide feedback to the user. As mobile phone software becomes increasingly sophisticated, user experience continues to improve. However, traditional sound feedback is no longer enough to meet the needs of smartphone users. As a result, some smartphones have begun using vibration motors to provide vibration feedback. As smartphones become thinner and thinner, traditional rotor motors can no longer meet new requirements, and linear motors have been developed.
Linear motors, also known as LRA vibration motors, are designed to provide tactile and vivid vibration feedback. The purpose of installing it on a mobile phone is to alert users of incoming messages by emitting vibrations, ensuring that important notifications are not missed when the phone is in silent mode and cannot detect text messages and incoming calls.
Linear motors work similarly to pile drivers. Essentially, it functions as a spring-mass system that directly converts electrical energy into linear mechanical motion. This is accomplished by using AC voltage to drive a voice coil, which presses against a moving mass connected to a spring. When the voice coil is driven at the resonant frequency of the spring, the entire actuator vibrates. Due to the direct linear motion of the mass, the response speed is very fast, resulting in a strong and obvious vibration feeling.
Apple said the tactile feedback linear motor is an advanced vibration motor that can provide different feelings according to different scenarios, allowing users to experience different vibrations. Additionally, it provides subtle vibrations at different locations on the touch screen.
In fact, the great function of this new type of linear motor is to improve the sense of touch of the human body and to make the whole product thinner and lighter. In addition to its simple structure, it features precise positioning, fast response, higher sensitivity and good follow-up.
