TWS Headphone Pressure Sensitive Module TS2223
TWS Headphone Pressure Sensitive Module TS2223
In order to better meet the pressure touch requirements of TWS headsets, Titan Technology has released a TWS headset "true pressure" detection module with sensitivity comparable to Apple's AirPodsPro: TS2223. This system is based on the pressure-sensitive characteristics of the self-developed sensor material of Titan Technology, which can realize operations such as single-click, multi-click, and long-press, while perfectly solving the pain points of easy mistouch, poor experience, complex integration, and high cost.
The TWS headset pressure sensing solution of Titan Technology does not require additional AFE drivers and MCU chips. It can reuse the TWS headset main control platform or in-ear touch chip, truly achieving extremely low cost, high sensitivity and linearity, and perfect Consistent hand feeling (unique adaptive algorithm), no need for post-calibration, simple assembly (SMT patch), high assembly yield and extremely short delivery cycle.
At the same time, TWS's TWS headset pressure sensing solution can be perfectly adapted to all mainstream Bluetooth platforms and mainstream solutions currently on the market. With full independent intellectual property rights from materials to modules to algorithms, TTS can provide a more comprehensive The one-stop service for pressure sensing solutions can respond to customer needs more quickly.
The TS2223 earphone pressure-sensing module is based on the principle of true pressure detection, so it has the advantage of high linearity
● Focus on linearity, and can appropriately relax the restrictions on other parameters such as size and packaging;
● High linearity sensor with self-calibration algorithm can avoid assembly products Calibration;
● The relative pressure calculation formula dP=dA/k can be derived;
● The algorithm is simple and reliable, with low MCU resource requirements, and can be integrated into the main control scheme;
● Effectively reduce costs;
● Strong adaptability to pre-pressure, adaptable to tolerances Wide range;
● Simplified core indicators of the sensor: linearity and slope;
● Can detect negative pressure;
