Design a 'Cancel BT Connection Button'. When an unknown BT device maliciously connects, long press the button for 3 seconds to cancel the connection of the unknown BT device.
Fine quality capacitors are used in keyAreas, which perform well in parameters such as dissipation factor, leakage current, ripple​ current, and ​, significantly improving the speed dynamics, texture, and density of sound, and particularly enhancing the overall quality of high, medium, and low frequencies. The capacitance has fine dissipation factor, which can effectively reduce the impact of temperature, voltage, and frequency on sound quality. Capacitors with low leakage current not only reduce aging rate and prolong service time, but also significantly reduce noise. Low ​ capacitance can reduce high-frequency impedance, improve dynamic response speed, and enhance sound performances.
