AI Technical Summary
In electronic atomizers, the stability of the microphone detection circuit is affected by drastic power fluctuations and high-temperature environments, resulting in unstable count/frequency measurements, which are particularly difficult to maintain accuracy under high-temperature and large power fluctuation environments.
By using a microphone clock-based calibration method, a microphone counter is used to count the pulses of the microphone clock within a preset unit counting interval. The total resistance value of the calibration range resistor group is adjusted to ensure that the pulse count value remains within the target working counting range, adapting to drastic changes in power supply and temperature, and achieving frequency stability calibration.
Even under high temperature and large power fluctuations, the microphone clock frequency and count value remain stable, reducing errors caused by environmental changes and ensuring reliable triggering and atomization effect of the electronic atomizer.
