Mobile phones are an indispensable tool in our daily lives, and everyone will notice that there are many small holes in the bottom, sides, and back of the phone. So what exactly are these holes for? Many people may habitually use a toothpick to clean them, but this is actually incorrect and very important. Let's take a look at why.
We use our phones a lot, but many people don't know what these small holes on the bottom of the phone do. Different brands of mobile phones have different holes at the bottom. For example, the bottom design of the Apple mobile phone is relatively simple. The longest row of holes are the speakers, and it is from here that when we listen to a song or play music, the sound comes out.
The small hole in the middle is the charging port. In addition, we usually plug in the headphones through this small hole next to them. So what are the four little holes on the side used for? These are the microphone noise reduction holes.
In addition, attentive friends will also find that there is a hole next to the phone, this hole is the SIM card slot, and we insert cards here.
Some phones even have a small hole under the camera or on the top of the phone, and the design of different phones is different. So what is this hole for? It's also a microphone noise cancelling hole.
Normally, when we make a phone call or take a video, how is the sound recorded into the phone? It is through this hole at the bottom of the phone and the small hole on the back of the camera to receive the sound. The processing of the sound through these two small holes removes noise and makes the sound more realistic. This dual noise-canceling design is able to provide better call quality.
There is also a hole next to the phone's front camera, and this hole is for the sound of the earpiece. When we put our phone close to our ears, we are able to hear the sound more clearly.
After a long period of use, dust will inevitably enter these small holes. Many people may choose to use a toothpick to clean up and pick out the dust. However, this is actually incorrect and is not recommended for everyone.
Because these small holes are an important part of the phone, the toothpick is relatively sharp, if you accidentally poke these holes, the noise cancellation function will not work properly, which will affect the quality of the call. Moreover, repairing these holes after damage also costs a certain amount of money, and the benefits outweigh the losses.
So how do you clean these tiny holes?
We can use a cotton swab dipped in a little alcohol and gently rub it on the small holes. In this way, we can better recognize these small holes on the phone.
Through the above introduction, I believe you have a more comprehensive understanding of the role of the hole at the bottom of the mobile phone. Remember not to poke these holes, proper cleaning can ensure the normal use of the phone and the quality of calls.
