Linear Resonant Actuators (LRAs) deliver fast-response, energy-efficient tactile feedback using spring-mass resonance systems. With coin-style LRAs and surface-mount LRAs, our portfolio covers a wide range of applications — from wearables and consumer electronics to VR/AR systems and medical simulators.

Benefits of LRA Haptics

  • Fast response times for crisp, immediate feedback

  • Energy efficient compared to ERM motors

  • Compact and lightweight for portable devices

  • Consistent performance with tuned resonance

  • Flexible integration with both coin-style and SMT packages

Available Products

  • HD-LA0803-LW10-R – 8mm coin-style LRA for wearables & handhelds

  • HD-LA1307-SM – Surface mount LRA with patented design for VR & gaming

Applications

  • Wearables & smartwatches

  • VR/AR controllers

  • Gaming consoles & handhelds

  • Medical & training simulators

  • Consumer and industrial interfaces
