Application NFP-ELV1411A Linear Resonant Actuator For Sunu Band Sonar Smartwatch
Our LVM-Series linear vibration motors NFP-ELV1411A is used for SUNU BAND - a smartwatch that is enhancing mobility for the visual impaired. Beautifully designed, elegant and high-tech - Sunu Band is the first blind-accessible smart-watch that combines sonar technology with precision haptic feedback offered by LRA ELV1411A to augment spatial awareness and navigation. The SUNU BAND sonar smartwatch can vibrate to let the wearer know about obstacles ahead. We call it “FitBit for the blind.”
Just like a smartphone, Sunu Band has a Home (or standby) mode which allows the device to conserve power. Sunu Band’s HOME mode is the vibratory watch, which allows us to know the time by vibration patterns. When you are at HOME, you can read the time with the vibratory watch. You can follow the link to the vibration watch guide to learn how to use the vibratory watch or you may continue with this guide.
Sunu Band’s vibration watch allows you to know the time via a series of short or long pulses. You may choose to read the hour or the minutes depending on how you swipe on the touch pad. The Sonar and Obstacle Detection app allows us to detect/sense objects or obstacles that within our environment using the Sunu Band’s sonar sensor and haptic vibration feedback.
The app allows you to:
- - Activate the sonar sensor and vibration feedback.
- - Switch between sonar modes
- - Adjust the intensity of the vibratory feedback within the app’s configuration mode.
Entering into the app activates the sonar sensor and vibratory feedback. Depending on how you are aiming the Sunu Band’s sonar sensor (or how you are holding the device), you may feel vibration pulses. Simply aim the sonar away from you, making sure there are no objects/ obstacles adjacent to the sensor.

NFP - ELV1411A LVM Series Linear Vibration Motors
Need-For-Power Motor offers its LVM-series linear resonant actuator vibration motors
|AC 2.0 Vrms||235Hz||53mA||1.5G|
Due to their fast rise and fall times and superior braking ability, the NFP's linear resonant actuators (LRA) vibration motors are an excellent choice for haptic applications. Their relatively simple internal construction offers high reliability and exceptionally long life when compared with brushed ERM motors. NFP’s LRA have an internal mass that oscillates back and forth along the X-axis at its resonant frequency. They are an excellent alternative to brushless vibration motors as the only internal parts that are subjected to wear / failure are the springs.
