8mm LRA Linear Resonant Actuator Provide Powerful B Haptics Buzz
A linear resonant actuator is a precision vibration motor that produces an oscillating force across a single axis. Unlike a DC eccentric rotating mass (ERM) motor, a linear vibration motor relies on an AC voltage to drive a voice coil pressed against a moving mass that is connected to a spring.
• High-Precision Haptic Feedback – Provides accurate and fast response, ensuring a superior tactile experience in consumer electronics.
• Optimized Frequency Performance – Available in both 205Hz and 235Hz options, catering to different device requirements.
• Ultra-Compact 8mm Design – Small footprint makes it ideal for wearables, VR controllers, and compact mobile devices.
• Energy-Efficient Operation – Low power consumption maximizes battery life in portable applications.
• Durable & Reliable – Designed for long-lasting performance in high-demand environments like medical haptic feedback systems.
When the voice coil is driven at the resonant frequency of the spring, the entire actuator vibrates with a perceptible force. Although the frequency and amplitude of a linear resonant actuator may be adjusted by changing the AC input, the actuator must be driven at its resonant frequency to generate a meaningful amount of force for a large current.
The 8mm Linear Resonant Actuator (LRA) is a compact and efficient vibration motor designed for precise haptic feedback applications. Unlike traditional eccentric rotating mass (ERM) motors, LRAs operate at a fixed frequency, providing consistent and highly controlled vibrations. This model supports both 205Hz and 235Hz frequencies, ensuring compatibility with different application needs. Its low power consumption and high reliability make it an excellent choice for mobile, medical, and wearable technology.
To provide the most realistic feedback using eccentric rotating masses (ERMs) or linear resonance actuators (LRAs), you will need a device that implements advanced haptic effects. Replacement of Jinlong’s LRA MOTOR Y-AXIS, G0832012.
