Abstract
The utility model provides an anti-disclosure device of a mobile phone, which comprises a microphone of the mobile phone and a control processing unit connected with the microphone; wherein a switch which controls the switch-on and the switch-off of at least a control signal path and/or a microphone power path is arranged between the microphone and the receiving terminal of the control processing unit and/or between the microphone and the individual power supply chip. The external switch allows the audio signal transmission of the mobile phone to be controllable, so that the audio signals of the mobile phone can be safely and effectively isolated on some secret occasions so as to prevent the users' conversation from being eavesdropped by the intruders to the greatest extend, strengthen the protection of the confidential information and the individual privacy, and further avoid the disadvantages caused by the frequent switching and disassembly of the power supply.
Description
Technical field
The utility model relates to a kind of mobile phone leakage prevention device, under the situation of mobile phone standby or shutdown, can have the function that the protection mobile phone is not eavesdropped.
Background technology
Present mobile phone all is to allow the user be connected with each other by different communication networks, a large amount of mobile phones that use also bring various problems, wherein malicious intrusions can cause the user mobile phone under the situation of standby or shutdown by infinity transmitter, cause the individual privacy problem that leaks or the like, the user is caused irremediable loss.
Its microphone of present mobile phone directly is connected with control treatment part; Or independently-powered chip power supply structure is installed in the microphone employing additional.As long as mobile telephone system start work, then microphone just communicates automatically with control treatment part, manually the break-make of control audio signal.Mobile phone some occasion (as confidential session etc.) in actual applications like this, owing to forbid the wireless transmission of all audio signals of participant, usually require to close mobile phone, but so also can't stop hacker's malice eavesdropping, the hacker still can open by the mobile phone that Long-distance Control will be eavesdropped and eavesdrop; So the most frequently used practice is that the power supply of mobile phone is pulled down in the meeting, though that so effectively avoids being eavesdropped may, but the participant also can't receive any message simultaneously, as note, phone etc., has caused very big inconvenience and possible loss to the participant.
Summary of the invention
Situation in view of above-mentioned prior art, the utility model provides a kind of leakage prevention device of mobile phone, on the basis that does not change former mobile phone basic structure framework, move it phone under the situation of standby or shutdown, realization completely cuts off the audio signal that microphone receives, and reaches anti-purpose of divulging a secret under standby or the shutdown situation.
For achieving the above object, the leakage prevention device of a kind of mobile phone that the utility model provides comprises the connected control treatment part of microphone of mobile phone; Wherein between described microphone and control treatment part receiving terminal and/or at microphone and independently-powered chip chamber a control is set at least and connects the conducting of signal path and/or microphone power path and the switch of cut-out.Therefore, by external switch, with a kind of effective and efficient manner that is perfectly safe, the talk voice data of effectively having avoided the mobile phone user is by infinity transmitter; Also solve simultaneously the frequent switch mobile phone under secret environment and the problem of dismantling power.
According to scheme of the present utility model, related switch is not limited, and can select for use mechanical switch or contact witch all can.
According to the characteristics of above-mentioned application, described mechanical switch is single channel switch or binary channels linked switch.
In a word, the leakage prevention device of the mobile phone that the utility model provides, be not change on the integrally-built substantially basis of original mobile phone, on the microphone circuit, set up switch, can be safely and effectively the audio signal of mobile phone be completely cut off, with the not invaded person of the conversation content that ensures the user to greatest extent eavesdropping, solve can't manually control microphone in the prior art access whether, with the problem of picking of control audio signal; So just can solve the frequent switch mobile phone under secret environment and the problem of dismantling power, strengthen protection secret conversation content and individual privacy.
Description of drawings
Fig. 1 is a circuit diagram of the present utility model.
Fig. 2, Fig. 3 are another embodiment schematic diagrames of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described, is intended to help the reader to understand essence of the present utility model and the beneficial effect that is had better, but can not constitutes any restriction enforcement of the present utility model and protection range.
By shown in Figure 1.A kind of leakage prevention device of mobile phone, it is that a switch 2 is set on circuit structure between the microphone 1 of mobile phone and the control treatment part 3.This switch 2 is installed on the housing of mobile phone.Whether be switched on or switched off microphone 1 during for the ease of differentiation standby or off-mode, can select to have the switch 2 of display lamp.During normal the use, connect switch 2, people's sound is sent into control treatment part 3 after changing through microphone 1; When mobile phone is in standby or off-mode, cut off switch 2, make the circuit of 3 of microphone 1 and control treatment parts be in off-state, realize the anti-purpose of divulging a secret of mobile phone.
Fig. 2 has provided the embodiment different with Fig. 1.It is to set up a switch 4 on original microphone 1 with on the basis of the power supply circuits of independently-powered chip 5.This switch 4 is installed on the housing of mobile phone.During for the ease of the differentiation holding state, whether be switched on or switched off microphone, can select to have the switch 4 of display lamp.During normal the use, connect switch 4, sound is sent into control treatment part 3 after changing through microphone 1; When mobile phone is in standby or off-mode, cut off switch 4, make the circuit of 3 of microphone 1 and control treatment parts be in off-state, realize the anti-purpose of divulging a secret of mobile phone.
Fig. 3 has provided another embodiment.It is to have utilized Fig. 1, Fig. 2 combining structure, sets up the switch 2 of audio signal by adopting the switch 4 of setting up power supply circuits at the microphone 1 and 3 of the control treatment parts of mobile phone and microphone 1 and 3 of control treatment parts.Also can adopt simultaneously switch 4 and the external binary channels interlock of switch 2 formation in parallel mechanical switch.When mobile phone is in standby or off-mode, cut off external binary channels interlock mechanical switch, realize the anti-purpose of divulging a secret of mobile phone.Stop the invador to the stealing of user's voice data of mobile phone so effectively, avoid the loss of divulging a secret and being caused.
In the utility model, related microphone is existing as standardized products such as electret, MEMS microphones.
In the utility model, employed switch 2, switch 4 are mechanical switch; Or can select contact witch according to instructions for use.
In embodiment of the present utility model, selected control treatment part 3 can be selected different models according to different needs for existing device, different factory.In the present embodiment, related microphone is the electret microphone and the MEMS microphone of known technology; Described microphone links to each other with the control treatment part receiving terminal by the external mechanical switch.
