Fig. 1 is a block diagram of an electronic device 100, shown according to an exemplary embodiment. As shown in fig. 1, the electronic apparatus 100 may include a metal case 1 and an electrostatic absorption device 2. The static electricity absorbing device 2 may be connected to the metal casing 1, for example, the static electricity absorbing device 2 may be connected to the metal casing 1 through a metal elastic sheet or a metal welding spot, so that static charges carried by limbs of a user may be absorbed through the static electricity absorbing device 2 during the process that the user holds the electronic device 100 and contacts with the metal casing 1, and when the user subsequently holds other metal parts, for example, a door handle or a metal armchair, the limbs of the user will not carry or carry a very small amount of charges, and the phenomenon that the user generates electric shock with the metal parts can be avoided. The metal casing 1 may include a frame of the electronic device 100 or may be a middle frame structure of the electronic device 100, and the metal casing 1 and the static electricity absorbing device 2 may be directly connected or may be connected by other metal strips or metal ribs, which is not limited in this disclosure.

As shown in fig. 2, the electrostatic absorption device 2 may include a resistor 21, where the resistance value of the resistor 21 may be empirically determined, specifically, if the current generated when the user contacts the metal housing 1 is insufficient to generate the electric shock feeling by the user, for example, the resistance value of the resistor 21 may be greater than the resistor R1 when the current is empirically determined to be insufficient to generate the electric shock feeling by the user.

As can be seen from the above embodiments, in the present disclosure, based on the actual situation that the frequency of the user holding the electronic device is high, a technical solution of arranging the electrostatic absorption device 2 in the electronic device 100 is provided to absorb the electrostatic charge carried by the user during the period when the user holds the electronic device 100, reduce the amount of electrostatic charge carried by the user, and reduce the probability of generating an "electric shock feeling" when the user subsequently contacts with other metal pieces.

In this embodiment, the static charge carried by the user's limb may be either positive or negative due to the uncertainty of contact of the user's limb with the external environment. Therefore, in order to enable the electrostatic absorption device 2 to absorb positive and negative charges, the electrostatic absorption device may comprise an input 22 and an output 23, as shown in fig. 2, the input 22 may be connected to the metal casing 1 by a metal spring, and the output 23 may conduct out the absorbed electrostatic charges. When the electrostatic absorption device 2 is in the first state, the potential of the input terminal 22 is higher than the potential of the output terminal 23, and the input terminal 22 is connected to the metal housing 1, and since positive charges flow from high potential to low potential, the positive charges that the input terminal 22 can absorb at this time are conducted to the output terminal 23; when the electrostatic charge absorption device 2 is in the second state, the potential of the input terminal 22 is lower than the potential of the output terminal 23, and the input terminal 22 is connected to the metal housing 1, and since negative charges flow from a low potential to the potential, the negative charges that the input terminal 22 can absorb at this time are conducted to the output terminal 23. Therefore, in order to absorb positive and negative charges on the limb of the user, the static electricity absorbing device 2 can be switched between a first state and a second state, so that the absorption of positive and negative charges is achieved.

In one embodiment, still shown in fig. 2, the output 23 may be connected to the ground of the electronic device 100, so that static charge from the user's limb may be conducted to ground.

In another embodiment, as shown in fig. 3, the electronic device 100 may further include an electrostatic neutralizing device 3, where the electrostatic neutralizing device 3 is connected to the output 23 of the electrostatic absorbing device 2, so that the electric charges absorbed by the electrostatic absorbing device 2 may be introduced into the electrostatic neutralizing device 3, so that the absorbed electrostatic charges are neutralized by the electrostatic neutralizing device 3, and the influence of the absorbed electrostatic charges on the internal circuit of the electronic device 100 is avoided.

As shown in fig. 3, the static electricity neutralization apparatus 3 may include an ion generator 31 and an ion storage 32, wherein the ion storage 32 is connected to the ion generator 31 and the output end 23 of the static electricity absorbing apparatus 2, the ion storage 32 may be used to store ions generated by the ion generator 31, and the ions stored in the ion storage 32 may be neutralized with static charges introduced from the output end 32.

In one case, as shown in fig. 4, the ion store 32 may include a positive ion store 321 and a negative ion store 322, and the positive ion store 321 and the negative ion store 322 may be respectively connected to the electrostatic absorption device 2, so that positive charges conducted through the output terminal 32 may be neutralized with negative ions stored in the negative ion store 322, and negative charges may be neutralized with positive ions stored in the positive ion store 322.

In another case, as shown in fig. 5, the ion storage 32 may include a positive ion storage 321 and a negative ion storage 322, the electrostatic absorption device 2 may further include a switch circuit 24 located at the output end 23, the switch circuit 24 may include a third state and a fourth state, when the switch circuit 24 is in the third state, the negative ion storage 322 may be conductive to the electrostatic absorption device 2, and when the switch circuit 24 is in the fourth state, the positive ion storage 321 may be conductive to the electrostatic absorption device 2. Specifically, the processor in the electronic device 100 may control the switch circuit 24 to switch states according to the polarity of the charge absorbed by the electrostatic absorption device 2.

In the above embodiments, as shown in fig. 6 and 7, the electronic device 10 may further include a detection module 4 and a processor 5, where the detection module 4 is connected to the electrostatic absorption device 2, the detection module 4 may be used to detect whether the electrostatic absorption device 2 is switched to a state of absorbing electrostatic charges, and the processor 5 is connected to the detection module 4, so that when the detection module 4 detects that the electrostatic absorption device 2 is switched to a state of absorbing electrostatic charges, the processor 5 may instruct the ionizer 3 to generate electric charges, thereby implementing neutralization of the electrostatic charges absorbed by the electrostatic absorption device 2.

In order to neutralize the charge absorbed by the electrostatic absorption device 2 by the ions generated by the ionizer 3. In one case, the amount of charge carried by the limb of the user may be empirically determined, and the energy generated by the ionizer 3 may be adjusted based on the amount of charge of the general experience, i.e., each operation of the ionizer 3 may be preset to generate a preset amount of positive ions and negative ions. In another case, in order to avoid the trouble of obtaining the charge amount of the limb of the user in general experience, each operation of the ionizer 3 may be set to generate ions for neutralizing the electrostatic charge for a predetermined period of time, so that the electrostatic charge carried by the limb of the user may be reduced or even eliminated. The electronic device 100 provided in the present disclosure may include a mobile phone terminal, a tablet terminal, an electronic reader, and the like, which is not limited by the present disclosure.

Other embodiments of the disclosure will be apparent to those skilled in the art from consideration of the specification and practice of the disclosure disclosed herein.
