1 is a block diagram of an embodiment of a telephone that avoids eavesdropping in accordance with the present invention.

2 is a schematic diagram of signal control in an embodiment of a telephone that can avoid eavesdropping according to the present invention.

Referring to FIG. 1, a block diagram of an embodiment of a telephone 10 that can avoid eavesdropping according to the present invention is shown. In the present embodiment, the phone 10 that can avoid eavesdropping includes a microphone 110, a main system 120, a sensing module 130, an input module 140, a wireless module 150, a user behavior determining module 160, and a switch 170.

The microphone 110 is for receiving an external sound and converting it into a corresponding voice signal. In a typical telephone used, the microphone 110 is directly electrically connected to the main system 120, so that after being driven by the Trojan horse, the microphone 110 converts the daily conversation content of the user into a voice signal and is processed by the main system 120. The wireless module 150 sends out, causing the phone to become a bug.

In an embodiment of the invention, a switch 170 is provided between the microphone 110 and the main system 120, only when the user wants to use the present invention to avoid eavesdropping. The control switch 170 then turns on the connection of the microphone 110 to the main system 120, and disconnects the microphone 110 from the main system 120 when the user is not in use. This ensures that when the user is not using the telephone of the present invention, the microphone 110 cannot transfer the conversation content of the user to the main system 120, thereby effectively avoiding eavesdropping.

The sensing module 130 is configured to detect the state of the phone 10 that can avoid eavesdropping. For example, if the phone 10 that can be prevented from eavesdropping is a clamshell phone or a slide phone, the flip or the slider indicates that the phone 10 that can prevent eavesdropping enters a normal working state, and if the phone is a bar phone, it can be used in a bar phone. The surface is designed with a mechanical switch to control whether the user uses the phone 10 that can avoid eavesdropping, and can also determine the state of the phone 10 that can be used to avoid eavesdropping depending on whether the user presses the keypad lock. In the present embodiment, the state of the telephone 10 that can be prevented from being eavesdropped includes a normal working state and a standby state.

The input module 140 is used to input dialing and hanging signals. In the embodiment, the input module 140 includes a keyboard, a touch screen, and the like for transmitting the off-hook signal and the on-hook signal to the user behavior determining module 160.

The wireless module 150 is configured to receive and transmit a signal, and determine whether the power of the signal changes. In this embodiment, the wireless module 150 is divided into two parts: a transmitting end and a receiving end. The transmitting end is configured to receive the signal of the main system 120, and the signal is modulated into a high frequency and then transmitted, and the receiving end is used to receive the signal. The signal is demodulated and transmitted to the main system 120. In this embodiment, the specification of the wireless module 150 may be GSM, EDGE, WCDMA, CDMA2000, WIMAX or WIFI. In this embodiment, the wireless module 150 determines whether the power of the signal changes by the current change of the transmitting end or the receiving end.

The user behavior determining module 160 is configured to determine the user behavior according to the signal input by the input module 140, the signal power of the wireless module 150, and the detection result of the sensing module 130, and the switch 170 is turned off or on according to the user behavior. The connection between the microphone 110 and the host system 120 prevents the user from being eavesdropped. In this embodiment, the user behavior includes not using the phone, calling the phone, actively hanging up the phone, passively hanging up the phone, and talking.

In the present embodiment, the main system 120 outputs a clock signal to the user behavior determining module 160, and the user behavior determining module 160 is based on the detection result of the sensing module 130 at the same time and the signal input by the input module 140. And the power change of the signal of the wireless module 150 to determine the user behavior.

In the present embodiment, if the sensing module 130 detects that the state of the phone 10 that can avoid eavesdropping is in a standby state, it indicates that the user behavior is that the phone 10 that avoids eavesdropping is not used. If the sensing module 130 detects that there is a flip cover, a sliding cover or an unlocking signal input, it indicates that the state of the telephone 10 that can avoid eavesdropping enters a normal working state. If the sensing module 130 detects that the state of the phone 10 that can avoid eavesdropping is a normal working state, and the input module 140 inputs the off-hook signal, the user behavior determining module 160 determines that the user behavior is an upcoming call. If the sensing module 130 detects that the state of the phone 10 that can avoid eavesdropping is a normal working state, and the input module 140 does not input any signal, the user behavior determining module 160 determines that the user behavior is in a call. If the sensing module 130 detects that the state of the phone 10 that can avoid eavesdropping is a normal working state, and when the input module 140 inputs the hanging signal, the user behavior determining module 160 determines that the user behavior is an active hanging call. In this embodiment, if the other party hangs up the phone, the phone 10 that can prevent the eavesdropping will receive the pair. The party sends a message to suspend the communication, and the wireless module 150 stops the receiving end from receiving the signal. Therefore, if the power of the wireless module 150 detects that the signal is drastically reduced, the user behavior determining module 160 determines that the user behavior is a passive hang up call.

In this embodiment, if the user behavior determining module 160 determines that the user behavior is an upcoming call, the switch 170 turns on the connection between the microphone 110 and the main system 120, and if the user behavior determining module 160 determines that the user behavior is in the call. The switch 170 keeps the state of the connection between the microphone 110 and the main system 120 unchanged. If the user behavior determination module 160 determines that the user behavior is an active hang up call, the switch 170 disconnects between the microphone 110 and the main system 120. connection.

In this embodiment, if the microphone 110 is not turned on when the user is in a call, the switch 170 keeps the state of the connection between the microphone 110 and the main system 120 in an off state, and if the microphone 110 is turned on when the user talks, the switch 170 holds the microphone. The state of the connection between 110 and the main system 120 is the connected state. The phone 10 that can avoid eavesdropping in the embodiment of the present invention determines the user behavior by the user behavior judging module 160 to control the switch 170 to switch the connection between the microphone 110 and the main system 120, thereby effectively preventing the user from being eavesdropped. Referring to FIG. 2, a schematic diagram of signal control in the embodiment of the telephone 10 capable of avoiding eavesdropping is shown. In this embodiment, the signal is a signal for communication between the sensing module 130, the input module 140, the wireless module 150, and the user behavior determining module 160 in the eavesdropping phone 10 shown in FIG.
