The reason why the mobile phone has the sound of taking pictures:
The process of taking pictures with a SLR camera: press the shutter button, the mirror will rise quickly, the shutter curtain will open quickly and the light will shine on the film. After a while, the shutter will close, the mirror will fall, and a photo will be taken.
At the moment of taking a picture, the shutter is released and closed, and the mirror is lifted and lowered, which is what the subject calls "click" (the sound of the mirror is louder than the sound of the shutter).
As for mobile phones or card machines, there is no "mechanical shutter", but an "electronic shutter" is used to take pictures, and when the shutter is pressed, it becomes "silent". However, in order to meet the "psychological needs" of users, an "electronic sound" is usually set to simulate a "click" sound to make users addicted, and by the way, it is used as feedback for pressing the photo button.
