High Precision High Efficiency Quick Response And Low Noise Linear Resonant Actuators

Vibration Mode: Linear motors are capable of generating vibrations in a linear fashion rather than a rotational fashion. It can vibrate back and forth in one direction instead of rotating around a center.

The Huawei P30 Pro uses a NFP-ELV081530-B linear vibration motor. Such linear vibration motors are often used to generate haptic feedback, such as vibrating alerts and haptic notifications for mobile phones. It can simulate different types of vibrations, so that users can feel different tactile feedback and the best vibration effects when using the mobile phone.

Reminders and notifications: Linear motors can trigger vibrations upon incoming calls, text messages, social media notifications, etc. to communicate reminders and notifications to users. This vibration pattern can be adjusted according to different types of events, allowing users to sense the arrival of these important information through the sense of touch.

User interface feedback: It can also be used for user interface feedback to enhance the feedback effect of mobile phone operations. For example, when sliding on the touch screen, pressing a virtual button or performing other interactive operations, the linear vibration motor can simulate the touch of a physical button through vibration, providing more intuitive and realistic operation feedback.

Gaming and Media Experience: LRA linear resonant actuator also plays an important role in gaming and media applications. It can provide corresponding tactile feedback according to the characteristics of the game plot or media content, and enhance the user’s immersion and experience.



Why Choose NFP-ELV081530-B To Smartphone For Haptic Feedback?

I. High efficiency: Linear vibration motors are more efficient than traditional rotary motors. It can vibrate faster and respond more quickly. This makes it more precise and faster at providing haptic feedback.

II. Delicate touch: The LRA vibrating motor can provide more delicate and precise tactile feedback. It is capable of simulating different types of vibrations, such as gentle vibrations, strong vibrations, or continuous vibrations, etc., to provide a more engaging and realistic tactile experience.

III. Low power consumption: Compared with rotary motors, linear resonance actuator generally have lower power consumption. This is important for battery-operated devices like smart phones, as it extends battery life and reduces the need for frequent recharging.

IV. Quiet performance: Small LRA vibration motors are quieter than rotary motors. It does not produce loud spinning sounds, making the phone more silent when it vibrates, without disturbing the user’s environment or creating unnecessary noise.


To sum up, many mobile phone manufacturers, such as Huawei, Xiaomi, Lenovo, ViVo and Nubia ect, have seen the advantages of this linear motor and have put it into use. For motor’s detail please view as below👇:
