The loudspeaker of the iPhone7 is embedded on the right side of the home button, but if it breaks down, you will not hear the ringtone or cause a phenomenon that does not sound.
If it is a physical failure, you can use the iPhone7 as before by replacing parts, so please try to disassemble it with the following procedure!
In order to remove the loudspeaker, it is necessary to remove the liquid crystal, so you can remove the loudspeaker after removing the liquid crystal.
I will continue to disassemble the iPhone7 from here, but let's remove each tray of sim card first!
The sim tray can be easily removed using the pins that were included in the accessories at the time of iPhone purchase.
Since the iPhone7 is waterproof, a waterproof seal is affixed around the inside of the liquid crystal.
The tool in the image is called a heat gun, and it is not necessarily an indispensable tool though it is a tool which made the dryer strong if it says plainly.
If you are new to disassembly of the iPhone itself, you can work smoothly because the seal will be soft if you use it, but it is possible to substitute even a dryer once.
Up to now, the iPhone has been to wake the LCD from the home button side to the camera side, but this iPhone7 will open the LCD so as to wake up from left to right.
First of all, the tool is inserted into the position where the spatula is located and it floats little by little, but it becomes easy to disassemble when the suction cup (orange) is used together.
If you try to cause it forcibly, the liquid crystal side will crack, or it will lead to other failures, so we will open it slowly.
If you can float the liquid crystal even a little, it is good to insert a pick etc. like the image!
By doing this, the liquid crystal will not close again!
Now we will open the gap on the left side.
If you look closely at the inside of the part that could be opened, you will see a black seal or a white seal, but it will peel off regardless because it is a waterproof seal.
A waterproof seal is attached to one lap of the liquid crystal, but please pay attention only around the camera (upper part).
At the moment, I think that I was able to float the liquid crystal of the left and right slightly below, but the upper part does not decompose in the same way because the nail is caught inside, and a little knack is done.
If you pull the liquid crystal lightly in the direction of the arrow, there will be a slight gap between the main body and the liquid crystal, but when the waterproof seal comes into view, please peel off the seal in the gap.
By doing so, it is possible to wake up the LCD panel from the left side to the right side.
The first decomposition to be done after opening is work to remove the battery connector from the logic board, but since it is connected under the iron plate of the image, all screws of the red circle part are removed.
Four screws of this part are not Phillips, so please be sure to use a special tool because you can not open it unless you have a Y-shaped screwdriver!
I own several Y-shaped drivers, but I couldn't take them off right away because the sizes were slightly different.
I thought that I would try to disassemble it forcefully as it is, but I am using a special tool because the risk of licking from the experience up to now was high.
The red arrow part becomes the connector of the battery, but the connector can be removed from the logic board by lifting from the bottom to the top using the tool.
Next, the cable on the liquid crystal side is removed, but it decomposes in the same way as the method which removed the connector of the previous battery.
In the previous iPhone series, the connector relationship of the LCD was all gathered on the upper side (upper right), but in the case of the iPhone7, it is one of the changes because it became the lower right!
Because there is a connector in the inside when the screw can be removed, it is possible to remove it if it is made to lift from the bottom to the top.
Since the wiring of Wifi removed by STEP19 is stored in the groove next to the loudspeaker, you can remove it when you pull it in the front side.
Next, you can remove the loudspeaker if you can remove two screws that are enclosed in a red circle.
I was able to remove the loudspeaker of the iPhone7.
I have omitted the work of removing the battery on the way, but I remove it for clarity.
How to remove the battery of the iPhone7 is published on other pages, so please refer to it.
The loudspeaker of the iPhone7 is embedded on the right side of the home button, but if it breaks down, you will not hear the ringtone or cause a phenomenon that does not sound.
I will continue to disassemble the iPhone7 from here, but let's remove each tray of sim card first!
Decomposition of the iPhone7 will start from the place where all the screws are removed, but it will be removed from the Torx screwdriver.
Since the iPhone7 is waterproof, a waterproof seal is affixed around the inside of the liquid crystal.

Now we will open the gap on the left side.
This time, it is on the right side, but the liquid crystal is floated in the same way as before.
A waterproof seal is attached to one lap of the liquid crystal, but please pay attention only around the camera (upper part).
I was able to open it, but please be careful not to break it because a lot of connectors on the liquid crystal side are connected to the logic board.
The first decomposition to be done after opening is work to remove the battery connector from the logic board, but since it is connected under the iron plate of the image, all screws of the red circle part are removed.
Next, the cable on the liquid crystal side is removed, but it decomposes in the same way as the method which removed the connector of the previous battery.
Because there is one more connector under the previous cable, it will also be removed.
There is a cable of the camera in this part, but remove the screw attached to the iron plate as if the connector of the liquid crystal was removed.
Because there is a connector in the inside when the screw can be removed, it is possible to remove it if it is made to lift from the bottom to the top.
