Recently, a patent message about mobile phone vibration was exposed, which enables mobile phones to intelligently recognize the vibration state and reduce the noise caused by strong vibration. When the noise is greater than the ambient background sound, this new mechanism will automatically reduce the frequency of the mobile phone vibration motor. In this way, even if the mobile phone is placed in a noisy environment such as the desktop, it will not make people "jumpy" because of the vibration of a sudden call.

Apple applied for a new patent for vibration

The principle of Apple's vibration patent is that the phone microphone automatically detects the noise generated by iPhone vibration. When the noise is greater than the ambient noise, this new mechanism will automatically reduce the frequency of the phone vibration motor and give feedback signals. After feedback, the mobile phone sends commands to adjust the vibration intensity through calculation processing, so as to keep the noise intensity generated by the mobile phone vibration within a certain extent, without too much impact on users.

Mobile phone vibrator

Here, we may also introduce the principle of mobile phone vibration technology. In fact, it is very simple: inside every mobile phone that can vibrate, there is a mobile phone vibrator. The mobile phone vibrator consists of a micro ordinary motor plus a cam. Most motors are also covered with rubber sleeves, which mainly play the role of vibration reduction and auxiliary fixation, reducing the interference or damage to the internal hardware of the mobile phone when working. When rotating, the cam moves in a circle to generate centrifugal force. Since the direction of the centrifugal force changes with the rotation of the cam, the mobile phone has a large swing in the left and right directions when viewed continuously.

So why do most mobile phones vibrate from left to right instead of up and down? In fact, up and down vibration is completely achievable, but the resistance in the up and down direction is too large, and the vibration is not obvious, so the normal design naturally adopts the way of left and right vibration.

Is there any harm caused by mobile phone vibration? Generally speaking, mobile phone vibration will not cause direct harm to the human body. However, because the vibration consumes more power, long-term vibration will accelerate battery consumption and reduce service life. In addition, according to the survey report, it is easier for users to suffer from cell phone auditory hallucinations when the vibration is adjusted. Mobile phone auditory hallucination is a manifestation of obsessive-compulsive disorder. Although there is no phone, you can often hear your mobile phone ringing in your ears. Using the vibration mode will make this situation more obvious. Therefore, if the user's pressure is too high, it is easy to have auditory hallucinations, it is better not to continue using the vibration mode.
