Where is the microphone in the phone

There is a microphone on every mobile device, regardless of its cost or model. And in new smartphones, and in old button devices, this component performs the same function, namely, translates voice information from an analog form (sound waves) into an electromagnetic signal.

Where is the microphone usually located in the phone?

For greater convenience, the component is located at the bottom of the mobile device. This is done because when the user puts the speaker, which is located in the upper part of the device, to the ear, he needs to ensure the smallest distance from the receiving device to the sound source (namely the user's voice). That is why the most rational solution is to place the part receiving the sound from the bottom of the mobile device.

On older phones, microphones were divided into three types:

1. Coal is the most obsolete and common type.
2. Electronic - a more progressive model, which is characterized by better sound transmission and less noise.
3. Electronic with increased sensitivity is the most common type to date. The main feature is that not only the membrane of the microphone itself, but also the body of the device is involved in the reception of sound.

Also, in many modern devices, the connection of a third-party component for receiving voice signals is available. Usually this role is played by the headset. In this case, its location depends on the type and model of the headset or headphones.

The location of the microphone in phones of different brands

In the age of smartphones of the same type, this component is always located at the bottom of the case. This, as mentioned above, is due to the greatest practicality and convenience. In the days of push-button phones, when manufacturers experimented with models and forms of devices, the microphone could be located anywhere. And side and back and bottom. In order to determine where it is, it was enough to find a specific hole that could make it clear to the user what exactly it was worth saying to ensure the best quality of communication.

Attention! Do not try to pierce the microphone hole with sharp objects, since the membrane there is thin enough and it can burst, disrupting the functionality of the device.
