What is the difference between SMT motor and linear motor in mobile phone

China vibration motor factory will introduce SMT motor and linear motor to you today.

Let's start with what a phone motor is:

Mobile phone motor generally refers to the application of the vibration of mobile phone small da, his main role is to make mobile phone vibration effect;

The vibration effect serves as feedback to the user during the operation of the mobile phone.The vibration of our phones, the feedback of our buttons, all have to do with motors;

Let's start with the SMT motor

The SMT motor, as it's called, is similar to the motor we see in toy cars.Like conventional motors, they use electromagnetic induction, a magnetic field created by an electric current, to drive the rotor to spin and vibrate.

Nowadays, many mobile phone schemes mostly adopt SMT motor. Although the rotor motor has simple manufacturing process and low cost, it has many limitations.

Start slow, slow brake, for example, vibration omnidirectional, these defects will let users in the cell phone vibration obviously feel "slow", and the volume of motor rotor, especially thickness is hard to control, and the only mobile phone technology trend is more and more thin, even after the improvement, the SMT motor are still hard to meet the space dimension of the stringent requirements on the phone.

SMT motor from the structure is also divided into ordinary rotor and coin rotor ordinary rotor: large volume, poor vibration feel, slow response, its own noise.

Large-coin rotor: small volume, poor vibration feel, slow response, slight vibration, low noise;

Let's talk about linear motors

Like a pile driver, a linear motor is actually an engine module that converts electrical energy directly (note: directly) into linear mechanical energy by means of a spring mass that moves in a linear fashion.

For rotor motors, linear motors cost more.

At present, linear motors are mainly divided into two types: transverse linear motors (XY axis) and circular linear motors (Z axis).

The circular linear motor is slightly inferior to the transverse linear motor, which is the best vibration scheme at present.Circular linear motors cost about $5 and lateral linear motors between $8 and $10.

If the above introduction is not enough for you, you can go to the mobile phone experience store and feel the mobile phones with these motors respectively. After all, there are differences between the theoretical introduction and the actual hands-on experience, but we can clearly understand that linear motor is the best motor scheme at present.
