Since Shenzhen Guangli Technology Co., Ltd. launched the digital microphone chip that surpasses the industry level in 2023, it has redefined the airflow switch of the electronic cigarette microphone with its ultra-high sensitivity and stability. The digital microphone solution of Guangli Technology can reach -60+/-20PA in sensitivity and consistency. It is also the only company in the global electronic cigarette industry that dares to mass produce -60+/-20PA. After three years of continuous shipments, the total number has reached tens of millions, which fully verifies its high stability and reliability.
In order to meet the sensitivity requirements, many DTL e-cigarette products on the market usually place three-wire microphones at the top nozzle position to improve the sensitivity. This design is extremely risky because the top nozzle position has the most smoke and condensate, which is more likely to cause the microphone head to fail. The digital microphone head of the photolithography company has a sensitivity of up to -60pa ±20pa , far exceeding the industry level , allowing customers to design as they please. There is no need to adopt a three-wire microphone design. The microphone head is designed directly on the motherboard, which can be away from smoke and condensate, which is safer and more stable. At the same time, it saves the welding cost of the three-wire microphone and the installation cost of the three-wire microphone in the finished product, and there is no need to worry about the bad smoking experience.
Lithography Company -of 60pa digital microphone head solution is in the tens of millions. After three years of verification and tracking, it has ultra-high stability, and no customer has filed any complaints after the finished product was shipped. We dare to sign a letter of commitment with customers to ensure the consistency and stability of sensitivity.
1. Voltage anti-interference
The battery voltage will drop rapidly when it is loaded . For example, when the battery is unloaded, the fully charged battery voltage is 4.2V , and when it is loaded, it will drop to 3.7V or even lower instantly . When the battery voltage changes rapidly, ordinary microphones may have self-starting, delayed output, or interrupted output. The digital microphone of Photolithography Technology adopts a multi-level power supply filtering algorithm, which has perfect anti-interference performance and is not afraid of power supply fluctuation interference. It is very suitable for the application of high-power and large-smoke electronic cigarettes.
2. Temperature compensation
When the electronic cigarette is smoking continuously , the ordinary microphone head ( attached to the mainboard) will cause the sensitivity to decrease or cause false triggering due to the increase in the temperature of the mainboard. The digital microphone head chip of Photolithography Technology adopts a temperature compensation algorithm to maintain the consistency and stability of sensitivity even in a drastic temperature change environment . It is particularly suitable for the application of high-power and large-smoke electronic cigarettes .
- Oil and condensation resistant:
The photolithography digital microphone solution adopts a three-layer protection design. The first layer is a nano-oil-proof net, the second layer is the microphone shell, which plays a shielding and protective role, and the third layer is the oil-proof net on the silicone microphone shell.
In addition, because the distance between the oil-proof net and the silicone microphone is >1mm, the nano oil-proof net has the property of blocking oil, and it is difficult for smoke oil to leak onto the silicone microphone. Due to the double-layer oil-proof net design, it is difficult for smoke to deposit inside the silicone microphone, as shown in the following figure:
