In an era where user experience defines product success, Linear Resonant Actuators (LRAs) have emerged as the gold standard for precise, energy-efficient haptic feedback. From smartphones to surgical robots, discover how LRA technology is transforming industries.
A linear resonant actuator (LRA) is a type of electric motor that converts electrical energy into linear motion. The LRA consists of a coil of wire that is wrapped around a permanent magnet. When an electrical current is passed through the coil, it creates a magnetic field that interacts with the magnetic field of the permanent magnet. This interaction creates a force that causes the coil to vibrate. The frequency of the vibration is determined by the frequency of the electrical current.
X-axis linear vibration motor or z-axis linear resonance actuator has a number of advantages over other types of electric motors. They are compact, lightweight, and have a high power density. Linear vibration motors are also relatively simple to control, and can generate a wide range of frequencies, learn more.
LRAs are a good choice for applications where linear motion is required. Contact us to get solutions if your projects need linear vibration motors.

How LRAs Work:
Unlike traditional ERM motors, LRAs use resonant frequency-driven linear motion to generate vibrations. This mechanism eliminates mechanical wear, reduces power consumption by up to 50%, and enables millisecond-level response times.
LRA Motor-Applications:
Linear Resonant Actuators (LRAs) operate on a different principle compared to ERMs. These actuators use a voice coil and a movable mass attached to a spring, which vibrates at a resonant frequency when driven by an AC signal. This technology allows for more precise control over the vibration, making LRAs ideal for applications requiring a high-quality haptic feedback such as touchscreens and wearable devices. The efficiency of LRAs at their resonant frequency translates into lower power consumption and enhanced performance, which is crucial for battery-operated devices.
Tiny linear vibration motors, also known as linear resonant actuators (LRAs), have a wide range of applications due to their compact size and precise control. These motors are commonly used in mobile devices such as smartphones and wearables to provide haptic feedback, enhancing user experience by simulating tactile sensations. LRAs can generate vibrations with high precision and low power consumption, making them suitable for applications requiring delicate and subtle vibrations.
Consumer Electronics:
Apple’s Taptic Engine in iPhones uses LRAs to simulate realistic button clicks.
Medical Devices:
Surgical robots leverage LRAs for tactile feedback during minimally invasive procedures.
Automotive:
Tesla’s touchscreens use LRAs to mimic physical button presses, reducing driver distraction.
Competitive Edge:
Our LRAs feature ultra-thin designs (as slim as 2mm), customizable waveforms, and RoHS/CE compliance – ideal for OEMs seeking compact, reliable solutions.
