Common locations for mobile phone microphones include the bottom, top, near the back camera, side or frame, and near the bottom speaker. There is usually a microphone at the bottom or top of the phone. This design makes it easy to capture the user's voice during calls or video chats, reducing the problem of receiving sound caused by hand blocking. There is also a microphone near the back camera, which is mainly used to capture ambient sound when recording videos and improve audio quality. Some mobile phones hide the microphone in the side or frame, which saves space and is not easily blocked. In addition, the microphone of some mobile phones is located near the bottom speaker, which is conducive to noise cancellation or sound enhancement when playing music or videos.
The microphone of a laptop is usually located on the frame around the screen or on the cover around the keyboard. For example, microphones are often found in the middle of the frame above the screen, on both sides of the camera (if it is a dual array microphone, there is one on each side), and in the lower left and lower right corners of the keyboard area. The location design of the microphone helps to improve the clarity of calls and recordings while reducing the interference of ambient noise.
