• The next-gen VibeSense360™ TWS solution includes motion sensor hardware and software
• Running on the latest SmartMotion® ICM-45606 IMU, the next-gen VibeSense360 enables concurrent features of spatial audio, keyword assist, transparency for talk, head/UI gestures, and machine learning
• The 220 µA @ 50 Hz 6-Axis IMU delivers industry-leading performance and battery life for TWS applications

January 7, 2025

TDK Corporation (TSE:6762) announces the enhanced next-generation InvenSense VibeSense360™ solution for state-of-the-art spatial audio head tracking. Samples are available via direct inquiry with InvenSense sales.

VibeSense360™ enables concurrent execution of multiple features, including:

• Spatial Audio: Provides the most immersive and ultra-low-power spatial audio solution with TDK’s lowest-power 6-axis IMU, with the addition of a head tracking solution at 280 µA with industry-leading accuracy
• Transparency For Talk: Detects when the user is speaking through bone conduction and can automatically shift from noise cancellation to transparency mode, as well as pause any audio that may be playing
• Keyword Assist: Assists with always-on microphones in detecting human voice activity through bone conduction, ensuring more secure, accurate and ultra-low-power keyword detection while avoiding false triggers – even in noisy environments
• UI Gestures/Activity Detection: Enables a smooth user experience through always-on gesture detections like tap, double tap, triple tap, wide-area tap, head gestures like shake and nod, and activity/inactivity detection to trigger fitness/health monitoring
• Machine Learning: Using TDK’s machine learning algorithms built to run inside the IMU, VibeSense360™ can train the device to recognize certain customized activities and gestures, assigning commands or actions to allow the user’s head motion to control the TWS system

The VibeSense360™ solution is based on the InvenSense lowest-power SmartMotion® IMU, which has seen tremendous customer adoption since it was first announced at CES 2023.

“The next-gen VibeSense360™ solution gives customers more design flexibility by adding more UI gestures specially designed for TWS applications. Plus, it offers further system power savings by running multiple features including machine learning concurrently on the IMU,” said Pankaj Aggarwal, VP and GM of Consumer and Industrial Motion business unit at InvenSense, a TDK group company. “VibeSense360™ sets new standards for premium audio experiences in the TWS market.”
