Huvid Development background

TWS earphones mainly have active noise reduction mode, standby, call, voice playback and other working states. Under normal working conditions, Bluetooth power consumption is very low, with a current of approximately a few milliamperes. When using active noise reduction mode, call power consumption is the highest. The use of different inductors on different platforms, fabrics, and structural layouts significantly affects the overall efficiency of TWS earphones, mainly manifested in phenomena such as battery life, transmission distance (less than 10m), and jamming; Under the same conditions, traditional open magnetic circuit wound inductors generate induced magnetic fields that interfere with surrounding sensitive components, such as Audio PA, RF PA, speakers, etc., especially when the distance between the permanent magnet and the inductor inside the earphones is improperly designed, which can cause mutual interference or inductance failure due to magnetic leakage. Specific manifestations include current sound, background noise, connected pop sound, as well as poor reception sensitivity and sound quality. In the market trend of requiring efficiency and current pitch, in order to achieve high conversion efficiency and longer battery life of headphones, and reduce the risk of mutual interference,Shunluo has developed a stacked Mark point recognition high-performance MPHM series, a wound semi magnetic shielding MWPH series, and a high-performance (low DCR, high saturation current) integrated MWTC series of products.
