TDK Corporation (TSE:6762) expands its solution-focused offerings by announcing the InvenSense VibeSense360™ TWS solution suite. VibeSense360™ is a comprehensive portfolio of TDK solutions comprised of hardware and software dedicated to the TWS market. VibeSense360™ solutions help solve some of the most complicated problems TWS OEMs face, all while enabling state-of-the-art features that are unmatched by competition.

Within an evolving and multi-tiered TWS market, it is important for OEMs to offer competitive features to differentiate their products and break away from the pack. TDK’s VibeSense360™ solution suite gives all TWS vendors the ability to include significant feature value in their end products by taking advantage of TDK’s full array of expertise in this market.

Features that are enabled by VibeSense360™ include:

  • “Always On” Spatial Audio: VibeSense360™ combines the world’s lowest power 6-axis IMU at 280 µA with TDK’s software suite to provide industry-leading head tracking accuracy. This is the most essential piece for a truly immersive 360° spatial audio experience
  • Transparency For Talk (TFT): VibeSense360™ determines when the user is speaking via vocal vibration detection and can automatically shift from ANC to transparency mode and pause any audio that may be playing
  • Keyword Assist: VibeSense360™ can differentiate between user audio and ambient noise, assisting the microphones in the TWS system by ignoring surrounding audio. This not only creates less false keyword triggers but provides secure keyword detection
  • Machine Learning: Using TDK’s machine learning algorithms built to run inside the IMU, VibeSense360™ can train the device to recognize certain head gestures and assign commands or actions to allow the user’s head motion to control the TWS system

“TDK is much more than just a component company. Our ability to solve complex problems and provide complete solutions to customers, integrated into a single offering, is a unique value add that TDK has in our industry,” said Anson Yeganegi, Director of System Solutions at InvenSense, a TDK Group Company. “The TWS market is estimated to surpass the mobile market over the next few years, and TDK has every intention of being the leader in this space as a true ‘solution’ provider; VibeSense360™ is just the beginning.”

TWS-M601 andTWS-M602 are sampling to strategic customers and will be available later this year alongside even more feature enablement from other sensors.
