Abstract

The utility model relates to the telephone anti-tracking technology, in particular to an anti-tracing telephone device. The anti-tracing telephone device solves the problem that the prior telephone anti-tracking technology is ineffective when confronting GPS, GSM and other decoding programs. The anti-tracing telephone device comprises two call forwarding devices; the two call forwarding devices comprises a mobile phone and an interphone; the audio output line of the of the mobile phone is connected with the audio input line of the interphone; and the audio input line of the mobile phone is connected with the audio output line of the interphone. The anti-tracing telephone device has the advantages of simple principle and convenient manufacture, and can effectively realize the achieve the purpose of telephone anti tracking.

Description

The anti-tracking telephone device

Technical field

The utility model relates to phone anti-tracking technology, specifically is a kind of anti-tracking telephone device.

Background technology

Means such as existing telephone anti-tracking technology is normally taked to encrypt at the enterprising line number word of mobile phone/phone, program stops or hiding prevent tracked, yet these means just can lose efficacy when facing GPS, GSM and all kinds of decipher program.Thereby existing telephone anti-tracking technology is demanded urgently improving, to guarantee that mobile phone/phone can not be tracked in communication process.

Summary of the invention

The problem that the utility model lost efficacy when solving existing telephone anti-tracking technological side to GPS, GSM and all kinds of decipher program provides a kind of anti-tracking telephone device.

The utility model is to adopt following technical scheme to realize: the anti-tracking telephone device, comprise two telephone switching apparatus, described telephone switching apparatus comprises mobile phone and intercom, the audio output line of mobile phone is connected with the audio frequency incoming line of intercom, and the audio frequency incoming line of mobile phone is connected with the audio output line of intercom.

When using this device, the user puts through mobile phone in one of them telephone switching apparatus with the mobile phone/phone of oneself, under corresponding program was supported, the mobile phone in the telephone switching apparatus was connected automatically, and the voice signal that receives is transferred to the intercom that is attached thereto by its audio output line; Behind the intercom received speech signal, under setpoint frequency, transfer signals to the intercom in another telephone switching apparatus, and transfer signals to the mobile phone that is attached thereto by the audio output line of intercom, final this mobile phone is under corresponding software is supported, put through predefined mobile phone or telephone number, when treating that the other side connects, the mobile phone/phone that the voice signal that receives is sent to the other side gets final product.

Because the setting of telephone switching apparatus, make voice signal between the intercom of two telephone switching apparatus, transmit, and can keep very big distance (maximum speech range) between two intercoms, promptly two telephone switching apparatus separate at a distance, therefore, when the people wants that the phone of putting through by the user is followed the trail of by the person of putting through, or want to follow the trail of when dialling the hitter by connecting the phone person, can only track telephone switching apparatus with the direct communication of mobile phone/phone of dialling hitter/connection phone person, and can't track another telephone switching apparatus, naturally also just can't track mobile phone/phone with another telephone switching apparatus communication, thereby making to follow the trail of is interrupted, and has realized the purpose of anti-tracking thus.

The utility model principle of device is simple, and is easy to make, can effectively realize the purpose of phone anti-tracking.

Description of drawings

Fig. 1 is user mode figure of the present utility model.

Among the figure: 1-mobile phone, 2-intercom, the audio output line of 3-mobile phone, the audio frequency incoming line of 4-intercom, the audio frequency incoming line of 5-mobile phone, the audio output line of 6-intercom, 7-mobile phone/phone, 8-mobile phone/phone, 9-telephone switching apparatus; The dotted line of band arrow is represented radio communication.

Embodiment

The anti-tracking telephone device, comprise two telephone switching apparatus 9, described telephone switching apparatus 9 comprises mobile phone 1 and intercom 2, and the audio output line 3 of mobile phone is connected with the audio frequency incoming line 4 of intercom, and the audio frequency incoming line 5 of mobile phone is connected with the audio output line 6 of intercom.During concrete enforcement, the user puts through mobile phone 1 in one of them telephone switching apparatus 9 with the mobile phone/phone 7 of oneself, under corresponding program is supported, mobile phone 1 in the telephone switching apparatus 9 is connected automatically, and the voice signal that receives is transferred to the intercom 2 that is attached thereto by its audio output line 3; Behind intercom 2 received speech signals, under setpoint frequency, transfer signals to the intercom 2 in another telephone switching apparatus 9, and transfer signals to the mobile phone 1 that is attached thereto by the audio output line 6 of intercom, final this mobile phone 1 is under corresponding software is supported, put through predefined mobile phone or telephone number, when treating that the other side connects, the mobile phone/phone 8 that the voice signal that receives is sent to the other side gets final product.
