Why do most smartphones have a microphone in the bottom? Most smartphones have a microphone in the bottom because it is the most effective way to pick up sound. The bottom of the phone is closer to the mouth and therefore picks up sound better than the top or sides of the phone. Having the microphone in the bottom also helps to reduce background noise and makes it easier for the person on the other end of the call to hear you.
If you’re like most people, you probably take your smartphone with you everywhere. And if you’re like most people, your smartphone is always within easy reach. So why do most smartphones have a microphone in the bottom?
There are a few reasons for this. First of all, it’s more convenient for the user. When you’re holding your phone to your ear to make a call, the last thing you want to do is fumble around with the position of the microphone.
Having the microphone in the bottom means that it’s always in the right place for making calls.
Secondly, it’s more aesthetically pleasing. Having a hole in the top of your phone just doesn’t look as good as having one in the bottom.
And finally, it helps to reduce noise interference. If the microphone was at the top of the phone, it would be closer to your mouth and would pick up more ambient noise from things like chewing or breathing. By putting it at the bottom, those noises are less likely to be picked up by the mic.
Why Do Most Smartphones Have A Microphone In The Bottom?
Most smartphones have a microphone located at the bottom for several practical reasons:
- Noise Cancellation: Placing a microphone at the bottom of the device allows it to capture sound from the direction of the user’s mouth. This helps in reducing background noise during phone calls, making it easier for the phone to isolate the user’s voice for clearer communication.
- Ergonomics: When people hold their smartphones during calls or video chats, they typically place the bottom of the phone near their mouth. Having the microphone at the bottom naturally aligns it with the user’s mouth, ensuring better audio quality during voice calls.
- Speaker Placement: Smartphones also have a speaker or speakers at the bottom or on the front of the device. Placing the microphone nearby minimizes the risk of feedback or interference between the microphone and the speaker when you’re on a call or recording audio.
- Aesthetics and Design: Placing the microphone at the bottom allows smartphone manufacturers to maintain a clean and sleek design on the front and back of the device. It avoids the need for additional holes or openings on the front of the phone, which can affect the overall aesthetics.
- Water Resistance: Many modern smartphones are designed to be water-resistant or waterproof. Having the microphone at the bottom helps with this because it’s easier to seal and protect against water ingress compared to having multiple microphones in various locations on the device.
It’s important to note that while most smartphones have a primary microphone at the bottom, they often have multiple microphones in different locations to support various functions like noise cancellation, stereo audio recording, and more advanced audio processing. These secondary microphones may be located elsewhere on the device, such as the top, back, or sides.
What is the Use of Secondary Microphone in Mobile?
A secondary microphone is often used in mobile devices to improve sound quality during phone calls. The secondary mic can be used to cancel out background noise and provide clearer audio for the person on the other end of the call. It can also be used for recording video or audio.
What is the Tiny Hole at the Bottom of My Phone?
If you have a smartphone, chances are you’ve noticed a tiny hole near the bottom of the phone. This hole is called a microphone port and it’s there to help improve the sound quality of your phone’s built-in microphone. The microphone port allows outside noise to enter the microphone so that it can be filtered out and not recorded.
This helps to reduce background noise on your recordings and makes them clearer. If you’re wondering why your phone doesn’t have a microphone port, it’s because some phones use an internal MEMS (microelectromechanical system) microphones which don’t require one. So, if you see a tiny hole on the bottom of someone’s phone, now you know what it’s for!
Why are Small Built in Microphones Used in Smartphones?
The main reason that small built in microphones are used in smartphones is for the same reason that they are used in many other types of electronic devices; they are less expensive than larger microphones and they take up less space. In addition, the small size of these microphones allows them to be easily hidden within the phone itself, which can be important for aesthetic reasons.
While the small size of built in microphones may be one of their main selling points, it is important to note that this does not mean that they are lower quality than larger models.
In fact, many people find that the sound quality produced by these tiny microphones is just as good as what you would get from a larger model. This is due to advances in microphone technology in recent years, which have made it possible for manufacturers to pack a lot of power into a very small space.
Where is the Microphone Located on Most Phones?
If you’re looking for the microphone on most phones, you’ll find it located near the bottom of the device. On iPhones, the microphone is typically located on the bottom left side of the phone, just to the left of the charging port. On Android phones, the microphone is usually located on either the top or bottom of the phone, depending on manufacturer.
For example, on Samsung Galaxy devices, the microphone is located on the bottom right side of the phone.

Where is the Microphone Located on My Android Phone
If you’re looking for the microphone on your Android phone, there are a few places you can look. The first place to check is the top of the phone, near the earpiece. There may be a small hole here that indicates where the microphone is located.
If you don’t see a hole, try looking at the bottom of the phone. There may be a small grille or slit here that houses the microphone. If you still can’t find the microphone, it’s possible that it’s hidden behind one of the buttons on your phone.
Try pressing each button in turn and listening for a slight click or sound when you press it – this will indicate that there’s a microphone behind that button. Alternatively, consult your phone’s manual or contact its manufacturer to find out exactly where the microphone is located on your specific model of Android phone.
Does Speakerphone Use a Different Microphone
If you use your smartphone to make speakerphone calls, does it use a different microphone than if you just held the phone up to your ear? The answer is yes! When you’re on a regular call, your phone uses the primary microphone, which is located at the bottom of the phone.
This microphone is designed to pick up your voice clearly and cancel out any background noise. When you switch to speakerphone mode, your phone uses the secondary or top microphone. This microphone is not as good at cancelling out background noise, so it’s important to find a quiet place when using speakerphone.
How to Use Secondary Mic for Phone Calls
If you want to use your secondary microphone for phone calls, there are a few things you need to do. First, go into your phone’s settings and find the “Call” section. In here, you should see an option for “Microphone.”
By default, the primary microphone is selected, but you can change it to the secondary one by tapping on it.
Once you’ve done that, all of your outgoing calls will be routed through the secondary microphone. This can be useful in a number of situations – for example, if your primary microphone is damaged or not working properly.
Additionally, using the secondary mic can help to reduce background noise on your calls.
