Cell Phone Vibration

When it comes to cell phone vibration, it's actually not a very rare thing. This technology was widely used more than a decade ago, and in the early days, its main role was still in reminding people to avoid missing important messages in silent mode.

Phones vibrate because they have an internal vibrator, which is very small, usually only a few millimeters to a dozen millimeters.

Traditional cell phone vibrators consist of a miniature electric motor (motor) plus a cam (also called an eccentric wheel, vibrating terminal, etc.), and most of the motor is also wrapped with a rubber sleeve on the outside, which can play a role in damping and assisting in fixing the role of reducing its interference with or damage to the phone's internal hardware.

The principle of cell phone vibration is very simple, is the use of cams (eccentric device) in the cell phone internal high-speed rotation, the process of cams will do circular motion and generate centrifugal force, and the direction of centrifugal force will be with the rotation of the cams and constantly changing, at the same time, centrifugal force of the rapid changes in the motor also lead to the entire motor in the rapid jitter, and ultimately led to the vibration of the phone.

If you still don't get it, try to think of a time when the fan blades of your home fan broke off, and the whole fan was vibrating.

Another type of cell phone vibration relies on a linear vibration motor, which, unlike an eccentric wheel motor, has the advantage of a linear vibration motor. The linear motor alternates high-frequency currents in two coils, generating alternating positive and negative magnetic fields, and then produces the "vibration" we feel through repeated suction and repulsion.

This linear motor vibration simulates the feeling of pressing a key, and reduces the probability of damage to the phone's keys.

'Why do cell phones vibrate left and right instead of up and down?

This is because up and down vibration needs to overcome the gravity of the phone and other problems, the vibration effect is not as obvious as the left and right vibration, in the manufacturing process, the manufacturer must be as much as possible to minimize the production time and cost, the choice of left and right vibration method is not surprising.

'There's more than just one shape to a cell phone vibrator'

And with more and more things to put in a cell phone's internal space, the thinner the phone gets, the smaller the vibrator inevitably gets, and some vibrators are even made to be the size of a button, though the principle of vibration remains the same.

'Is the vibration effect of cell phones harmful to humans?'

Obviously, the vibration effect of cell phones is not directly harmful to human health; the only bad thing is that the vibration mode consumes power faster.

But for some users, using the vibration mode for a long time may produce hallucinations. Cell phone phantom hearing disorder is a manifestation of obsessive-compulsive disorder, even if there is no incoming call, the ear will often hear their own phone ringing, using the vibration mode will make this situation more obvious. I don't know if you have ever encountered this situation? If you always hallucinate hearing your phone vibrate, it's advisable not to keep using the vibrate mode.

The vibration of a cell phone is no longer just a reminder, and some manufacturers are starting to incorporate it into their feedback interactions. The more representative is after the iPhone 6s, 3D touch function added to the iPhone, Apple give this press action a vibration feedback, like really press a physical button, greatly improve the use of experience.
