Your iPhone may vibrate when listening to music. Several people have said that they notice a vibration when the sound comes out via speaker. Your iPhone has a built-in speaker system that lets you hear sounds when you play videos or music.
When music is played on your iPhone, you may feel your iPhone’s touch screen vibrating. This article explains how you can reduce this vibration.
Several iPhone models (iPhone 7 or later) are water-resistant. Water-resistant means no particles of liquid can get inside. And this requires a specific closed structure. Furthermore, one of the shortcomings of this design is to cause vibration in some conditions such as when the volume level is high. Especially thinner iPhone models experience this problem. Thus slight vibration is normal when music or game sound is high. Louder sounds mean stronger vibrations.
