Second, the Meizu POP really wireless Bluetooth sports headphones dismantling
MEIZU's Logo hides touch buttons.
First remove the motherboard and see the master chip.
This Hengxuan technology BES2000IZ TWS Bluetooth headset receiver chip. BES2000IZ is a next-generation Bluetooth audio solution with features such as full integration, high performance, low power consumption, Bluetooth v4.2 support, HIFI sound quality support, EQ and various audio technologies, and chip support active noise reduction. Meizu POP Bluetooth headset is not equipped with active noise reduction, but this headset is also passive noise reduction effect is good.
The cover is removed and the inside of the cover is a touch button.
The chip of the silk screen number 233DP in the figure is the Tontek Tongtai TTP233, which is a single-button touch detection IC used to detect touch key operations.
The silk screen number SZD 1741 chip is SGMicro St. State Microelectronics SGM40561, which is a charge management chip, with high input voltage, over-temperature, over-current protection, over-voltage protection, built-in charge flow control and so on.
The silk screen number 6366 chip XySemi Suzhou core microelectronics XB6366D, which is an integrated single-cell lithium battery protection IC, with protection against over-temperature, overcharge and short circuit protection.
