Application of gravity sensing technology in mobile phone

Gravity sensor is a device developed by Apple, and now it is applied to iphone and iPod/Nano 4. To put it simply, you used to hold your mobile phone upright in your hand. You turn it 90 degrees and turn it horizontally, and its page will automatically respond with your center of gravity, which means that the page is also turned 90 degrees, which is very human.

Mobile phone gravity sensing technology

Mobile phone gravity sensing technology: realized by piezoelectric effect. Simply put, the horizontal direction is determined by measuring the components of gravity in two orthogonal directions of an internal weight (the weight and the piezoelectric sheet are integrated). Through the force sensor, we can feel the change of the center of gravity when the mobile phone changes its posture, so that the mobile phone cursor can change its position to realize the function of selection.

Shake to switch interfaces and functions.

Mobile phone gravity sensing refers to the mobile phone's built-in gravity rocker chip, which supports the interfaces and functions needed for shaking and switching, such as turning songs and screens, turning mute, shaking and switching videos, etc. This is a very interesting function.
