Resonant Actuators

Resonant Actuators are used to generate tactile feedback and enable rich user experiences for many types of haptic applications. These non-rotating vibration devices are able to provide stable frequency, faster response and less power consumption than rotating vibration motors. These features, combined with advanced driver controls, make our resonant actuators best suited for smartphones, wearables, gaming, automotive and appliances. NMB offers a variety of devices for haptic feedback including Linear Resonant Actuators (LRA) and Direct Drive Actuators (DDA).

Features:

  • Enriched tactile expression
  • Smooth vibration
  • Quick response
  • High volume production

Applications:

  • Mobile phones
  • Car navigation
  • Driver feedback
  • Gaming
  • Home appliances

LRA Series

Our LRA products have a unique spring and damping structure to suppress high-order resonance and achieve wideband and clear vibration. The compact size is ideal for creating realistic tactile sensations in mobile and gaming equipment.

DDA Series

MinebeaMitsumi has designed a first of its kind Direct Drive Actuator (DDA) that employs a simple solenoid structure which has been flattened to fit behind an automotive user interface. The patented structure creates z-axis motion that provides a robust haptics expression while maintaining simple electrical operation.
