Technical Field

The utility model relates to a network security technical field especially relates to a smart mobile phone with prevent eavesdropping and prevent secretly clapping the function.

Background

At present, a microphone of a smart phone is connected with an audio processing module, and the audio processing module is connected with an a/D analog-to-digital conversion module. When a user calls through the smart phone, voice signals collected by the microphone sequentially pass through the audio processing module, the A/D analog-to-digital conversion module and other processing circuits, and finally voice data are sent to a call opposite terminal through the radio frequency circuit.

With the popularity of smartphones, spyware may enter the phone in a variety of ways. The software can open a microphone of the mobile phone to automatically record under the condition that a user does not know the software, so that personal privacy and secret of the user are revealed. Not only spyware, but most of the APPs on mobile phones now have this ability, so long as APP designers or operators "like", APPs on user's mobile phones can become potential spyware, making mobile phones become eavesdroppers.

For the above risk threats, the smart phone user has almost no more effective prevention method except for 'not taking the mobile phone with him'.

Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the drawings in the embodiments of the present invention are combined below to clearly and completely describe the technical solutions in the embodiments of the present invention. It is to be understood that the embodiments described are only some embodiments of the invention, and not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

The switch can be a key switch or a touch switch, and can be arranged on the left side, the right side or the back of the shell of the smart phone.

Specifically, when a user presses or touches the switch to enable the switch to be in a closed state, the audio circuit module, the video circuit module and the A/D conversion module start to work, and when a call or a shooting is completed, the user releases the switch to enable the switch to be in an open state, and the audio circuit module, the video circuit module or the A/D conversion module stops working.

Further, the smart phone may be provided with an indicator light, which is turned off when the audio circuit module, the video circuit module or the a/D analog-to-digital conversion module is prohibited from operating, or turned on otherwise.

Preferably, the indicator light is multiplexed with the existing indicator light on the smart phone, and different states are represented by different colors or different flashing frequencies.

The following describes a smart phone with eavesdropping and candid camera prevention functions in detail.

As shown in fig. 1, the output end of the audio processing module of the anti-eavesdropping and anti-candid smart phone is connected with the ground wire on the mobile phone circuit board through a triode T, and the triode T is controlled by a switch on the mobile phone shell. The port 1 in fig. 1 is connected to a switch on the mobile phone case, and in a normal state, the switch on the mobile phone case is in an off state, the triode T is saturated, the output signal of the audio processing module is grounded, no signal is sent to the a/D conversion module, and obviously no signal can be eavesdropped through the microphone. When a call is needed, the switch is pressed or touched to be closed, the triode T is cut off, and the output of the audio processing module is normally sent to the A/D conversion module. When the conversation is finished, the user releases the switch to enable the switch to return to the disconnected state, the triode T is saturated, and the audio processing module is forbidden.

Fig. 2 is another embodiment of the present invention. The output signal of the anti-eavesdropping smartphone A/D conversion module passes through an AND gate, and the other input end of the AND gate is controlled by a switch on the casing, namely a port 2 in the graph 2 is connected with the switch on the casing of the smartphone. Normally, the switch is in an off state (1), the output of the NOT gate is 0, no matter what the signal output by the A/D conversion module is, the output of the AND gate is 0, and the A/D conversion module is forbidden. When a call is needed, the user presses or touches the switch to close the switch (0), the output of the NOT gate is 1, and the output of the A/D conversion module is allowed. When the conversation is over, the user releases the switch to enable the switch to return to the disconnected state, and the output of the A/D conversion module is forbidden again.

Alternatively, the switch may be designed as a time delay switch, and after being in a closed state for a predetermined time, the switch automatically returns to be opened, so that the requirement of a user for talking through a wireless earphone or the like in a vehicle driving or other specific occasions can be met. The predetermined amount of time is related to the amount of time the user presses or touches the switch.

In particular, a specific implementation of the time-delay electronic switch can be as shown in fig. 3. In the figure, the key or touch switch 3 on the casing is normally on, the transistor T1 is in an off state, and the port 4 is a switch control end of the access circuit. The user presses a button or touch switch on the housing to close, and the power source charges the capacitor C through the resistor, so that the transistor T1 is in a saturated state. The longer the key press time, the more fully the capacitor C is charged. After the user releases the key, capacitor C discharges, maintaining transistor T1 in saturation for a period of time. Discharge is complete and T1 is cut off. Obviously, the length of the delay is related to the user's key press time and the design of the capacitor C and the resistor R.

The above description is only for the specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention should be covered by the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
