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.
The InvenSense VibeSense360 TWS solution suite is a comprehensive portfolio of TDK solutions comprised of hardware and software. Among the new solutions included in this development package is a low-power 6-axis inertial measurement unit (IMU) for accurate head tracking, an on-chip accelerometer that captures vocal vibration, and a machine learning on-chip solution with significant power savings on main processor/MCU. Features enabled by VibeSense360 include: “Always On” spatial audio, keyword assist, TFT mode (Transparency for Talk), and machine learning.
For "Always On" Spatial Audio, VibeSense360 combines the world's lowest power 6-axis IMU at 280µA 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. It also manages an accelerometer or bone conduction sensor and 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.
And 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.
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," says 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."
The TDK TWS-M601 is the low power 6-axis IMU for head-tracking, and the TWS-M602 adds an on-chip accelerometer to capture vocal vibration from the user to remove ambient audio, enable keyword assist or TFT mode. It also supports machine learning on-chip with significant power savings on the main processor/MCU.
Both the TWS-M601 and TWS-M602 are sampling to strategic customers and will be available later in 2023 alongside even more feature enablement from other sensors.
