The secret of smart phone holster

The popularity of various mid-and high-end handsets has led to a growing number of users equipped with smart holster. I recently also started a mobile phone holster, mainly to prevent broken screen (large screen mobile phone shortcomings). Now the mobile phone holster is mostly intelligent sleep, light the function of the screen, then we will look at its principle.

Intelligent leather case is the principle of electromagnetic induction, the key is to separate the magnetic chip.

In the phone embedded a magnetic sensor (my Huawei 3X next to the front camera, with headphones can be sucked), this element may be the hall element (the cell phone Hall sensor) is mainly used for mobile phone flap or slide position detection, commonly used models are, MST's mh248 and Diodes ' AH180, which belong to the Micropower Hall switch), when the lid is closed, the magnetic sensor will send a signal to the phone screen, the sensor switch generated action to switch the display to a pre-designed special interface (phone preset), such as call, clock, weather, information, Framing, controlling music playback, recording memos, etc. The magnet leaves and resumes its normal desktop display. At the same time, you need to put a small patch on the battery cover of the Sleeping holster (the original back cover has a black patch on it is the magnetic separator), making (small magnetic chip, magnetic sensor, magnetic patch) San du all in the same vertical plane, realizing the sleep when the lid is closed, and the working principle of anti-sleep when the flap. With a large magnet placed in the magnetic sensor position, the phone screen automatically sleep, remove the magnet, the screen will automatically unlock light.

Many people think that mobile phone sets affect the appearance of mobile phones and make the phone does not dissipate heat, plastic shell also contains benzene, with the call, send and receive, benzene with the respiratory tract directly into your organs, the higher the temperature, benzene released more severe. In fact, the use of mobile phone sets of materials, there are leather, silicone, fabric, hard plastic, soft plastic sets, velvet, silk and so on. As long as it is not very inferior, there is no danger of benzene. Now the mobile phone set from the beauty, personality, and quality have been very good. If you worry about heat dissipation, can completely in the phone when the hot, remove the phone cover, of course, generally watch video, call, not yet, my mobile phone holster has always been not picked, may be due to the credit of Huawei HiSilicon processor. Of course, mobile phone sets or mobile phone long-term use will carry a large number of bacteria, this should be noted.
