Embodiment Construction

[0009] see figure 1 , which is a schematic structural diagram of a portable electronic device 10 in a preferred embodiment. The portable electronic device 10 may be a mobile phone, a game console, MP3, MP4, etc., which are powered by batteries. The portable electronic device 10 includes a casing 100 , grooves 200 are formed on four side walls of the casing, and pressure detectors 108 are disposed in the grooves 200 .

[0010] Please also see figure 2 , which is figure 1 The shown functional block diagram of the portable electronic device 10 includes a battery 102 , a power manager 104 , a working unit 106 , a pressure detector 108 , a trigger 110 , and an output unit 112 .

[0011] The power manager 104 is used to manage the battery 102 to provide power for the working unit 106 . For example, to control the on-off of the power supply, that is, switch the machine; for example, to control the conversion of the power supply, the voltage of the battery 102 is converted into th...

Abstract

A portable electronic device comprises a cell, a power manager and a working unit; wherein, the power manager is used for managing the power supply work of the cell for the working unit; the portable electronic device also comprises a pressure detector and a trigger; the pressure detector is used for detecting the ambient pressure and generating control signals to the trigger after the ambient pressure reaches the preset value; the trigger generates and outputs trigger signals to the power manager according to the control signals sent by the pressure detector; the power manager further responds to the trigger signals and stops supplying power for the working unit. So, when the portable electronic device falls into water, the pressure of the water forces the pressure detector to generate the control signals, thereby triggering the portable electronic device to close down and avoiding electronics from damage caused by short circuit owing to soaking.

Description

technical field [0001] The invention relates to an electronic product, in particular to a portable electronic device using a battery. Background technique [0002] Portable electronic products have the characteristics of small size and convenient carrying. It is for this reason that these electronic products also increase the possibility of falling into the water. [0003] After the electronic product is immersed in water, if the electronic product is in the working state at this time, the circuit on the circuit board will be short-circuited, and the circuit will be burned at this time. Contents of the invention [0004] In view of this, it is necessary to provide a portable electronic device that can prevent water damage. [0005] A portable electronic device, which includes a battery, a power manager and a working unit, the power manager is used to manage the battery to provide power for the working unit, the portable electronic device also includes: a pressure detecto...
