00:00:00,766 --> 00:00:04,166

In this lesson we are going to learn about the vibration chips

2

00:00:04,966 --> 00:00:06,300

In the iPhone mainboard,

3

00:00:06,600 --> 00:00:11,033

the vibration chip is mainly used to convert the vibration signal into power supply,

4

00:00:11,100 --> 00:00:13,633

providing working voltage for the vibrator

5

00:00:13,966 --> 00:00:19,966

The vibrator produces vibration of different amplitude according to the voltage change

6

00:00:21,100 --> 00:00:25,766

The vibration chip and audio amplifier are the same on iPhone 6s and above,

7

00:00:26,066 --> 00:00:27,400

and can be replaced

8

00:00:32,333 --> 00:00:35,200

Their output power supply is connected to the receiver,

9

00:00:35,366 --> 00:00:37,833

called the receiver power amplifier,

10

00:00:38,900 --> 00:00:42,466

connected to the speaker, called the speaker power amplifier

11

00:00:43,100 --> 00:00:44,966

It's connected to a vibrator

12

00:00:45,266 --> 00:00:47,133

It's called a vibration chip

13

00:00:48,966 --> 00:00:52,033

The vibration chip damage will lead to the failure

14

00:00:52,033 --> 00:00:54,566

of the vibration function of the mobile phone,

15

00:00:55,000 --> 00:00:57,666

and it needs to be replaced with the same model

16

00:00:58,566 --> 00:01:01,866

Now let's go to the mainboard and learn about the vibration chip

17

00:01:03,533 --> 00:01:05,500

This is the iPhone 8 mainboard

18

00:01:06,233 --> 00:01:08,466

It has a vibration chip at the bottom,

19

00:01:09,200 --> 00:01:12,333

rectangular, shiny, glass chip

20

00:01:14,066 --> 00:01:15,666

It's similar to this chip,

21

00:01:16,266 --> 00:01:17,333

and this chip,

22

00:01:17,700 --> 00:01:19,100

and this chip on the top

23

00:01:19,700 --> 00:01:22,566

This chip is called the receiver power amplifier,

24

00:01:23,033 --> 00:01:25,200

this is called the speaker power amplifier,

25

00:01:25,666 --> 00:01:27,500

and this is the vibration chip

26

00:01:28,000 --> 00:01:30,300

The three chips are of the same model

27

00:01:30,433 --> 00:01:33,000

and can be interchangeable with each other

28

00:01:34,066 --> 00:01:36,000

This is the iPhone xs mainboard,

29

00:01:37,366 --> 00:01:39,933

and its vibration chip is in this position

30

00:01:40,766 --> 00:01:44,966

We can find that these three chips have similar appearance,

31

00:01:45,333 --> 00:01:47,400

and the model number is the same

32

00:01:49,433 --> 00:01:51,766

These three chips are interchangeable

33

00:01:52,833 --> 00:01:55,000

This is the iPhone XR mainboard,

34

00:01:55,466 --> 00:01:58,100

and its vibration chip is in the rear slot

35

00:01:59,566 --> 00:02:01,700

The glass chip is the vibration chip

36

00:02:02,533 --> 00:02:06,366

The one that looks like it up here is the speaker amplifier

37

00:02:07,133 --> 00:02:12,033

These two chips models are the same, can be universal substitution

38

00:02:13,433 --> 00:02:15,533

Ok, that's all for this lesson
