Abstract: This present invention is a handle with a hidden belt, applying to a handle attached on a portable device, which uses torsion springs to draw the belt into the handle. Thus, a user can not only carry the portable device with the handle, but also shoulder or hang the portable device with the hidden belt of the handle.

Abstract: A portable electronic device disposed in a car is provided. The portable electronic device includes a power switch, a vibration sensor and a controller. The power switch is used for providing a first power at a first state and providing a second power at a second state. The vibration sensor is used for outputting a vibration signal after sensing the vibration of the car. The vibration sensor is used for terminating the output of vibration signal when not sensing the vibration of the car. The controller is electrically connected to the vibration sensor and the power switch. When the controller receives the vibration signal, the controller controls the power switch to be at the first state and provide the first power. When the controller does not receive the vibration signal, the controller controls the power switch to be at the second state and provide the second power.
