Smarter HearablesEnabled by TDK Sensing SolutionsTrue Wireless Stereo earbuds, or TWS for short, have taken the world by storm as the latest “must have” tech gadget. These days, you cannot walk down the street without seeing these technological marvels in every ear that passes you by. TWS headsets are driving some of the highest revenues in the world – with projections to have them surpass the mobile business by 2026! If you haven’t jumped on this bandwagon yet, it’s only a matter of time! Unlike the earbuds of old, today’s TWS headsets are jammed packed with features enabled by the industry’s latest sensor solutions. Features like Spatial Audio, Active Noise Cancellation, Voice Activity Detection, and activity tracking are all capable because of the sensors found inside any standard TWS earbud. TDK’s solution portfolio for TWS headsets leads the way for innovation and feature enablement, bringing more value to the application, and a better user experience to the user! Next-gen VibeSense360: is a comprehensive TWS solution suite encompassing motion sensor hardware and software dedicated to the TWS market. It enables concurrent multiple features like spatial audio, keyword assist, Transparency for Talk, head/UI gestures and machine learning running simultaneously on the latest ICM-45606 IMU. SmartSound*: Features such as Active Noise Cancellation, Transparency Mode, Beam Forming, Voice Isolation, etc all require extremely high performance/lower power MEMS microphones to achieve. TDK’s audio solutions are built with this in mind and lead the way on power and performance in every way. |
TWS Features TDK Can Enable |
 | Immersive Spatial Audiowith TDK SmartMotion®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 that output Yaw, Pitch and Roll data at 280 µA. The smart gyro calibration and super low noise ensure the industry-leading accuracy. |
TFT (Transparency for Talk) Mode/Keyword Assistwith TDK SmartMotion®Long gone are the days of dedicated voice accelerometers used to detect when the user is speaking. Goodbye to voice detection using microphones that cannot determine the difference between the user and someone within range. TDK’s VibeSense360 solution suite uses the accelerometer inside our 6-axis IMU as a vocal vibration sensor that can recognize when the user is speaking to either shut down or turn the system onto full power. This not only saves overall BOM costs for a TWS system, but significant power by removing an entire sensor from your platform! |  |
 | UI Gesture/Activity Detection with Machine Learningwith TDK SmartMotion®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. 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. |
Transparency Mode / Beam Forming / Active Noise Cancellationwith TDK SmartSound™MEMS microphones are at the heart of any legitimate TWS product. Most headsets will use anywhere from 4-6 MEMS microphones in their systems for a variety of use cases. TDK has the highest performance/lowest power digital MEMS microphones in the world – a perfect fit for any TWS solution! |  |
