Abstract
The utility model discloses a kind of communication apparatus protective sleeve of band signal compensate function, protective sleeve is provided with slidably antenna, when skidding off this antenna from protective sleeve, the middle part of this antenna or end corresponding with the antenna of communication apparatus body.The utility model is according to the position of antenna in communication apparatus; a slidably duplex antenna is inserted in its protective sleeve; in the bad border that movable signal is more weak; skid off the duplex antenna in protective sleeve; the head of human body and the decay of hand to mobile phone radiofrequency signal is made to be reduced to minimum; thus indirectly enhance the radiofrequency signal of mobile phone, thus ensure carrying out smoothly without letter communication.Esy to use, safe and reliable, protective sleeve not only has defencive function, and has the function of radio frequency signal compensation simultaneously, guarantees that the place signal is weak can normally use.
Description
Technical field
The utility model belongs to communication technical field, relates to the radio communication of communication apparatus, is specifically related to a kind of communication apparatus protective sleeve of band signal compensate function.
Background technology
At present, people when using the hand held mobile communication product such as mobile phone, human body when using mobile phone, as: when making a phone call, the head of human body and hand can cause radio frequency signal to produce decay.Mobile phone generally can between 6dBm-12dBm, can cause like this and even cannot carry out causing away from mobile base station or when wireless signal is more weak to decline without letter communication quality.User usually prefers and adds a protective sleeve to mobile terminals such as the mobile phones of oneself; to strengthen aesthetic feeling and the few contaminated destruction with producing during percussion of protection mobile phone itself of mobile phone; but solid dielectric difference that this overcoat produces is also from producing different decay to mobile phone wireless signal in varying degrees, the inappropriate even decay of part material reaches more than 10dBm.
Utility model content
In order to solve the above-mentioned problems in the prior art, the utility model provides a kind of communication apparatus protective sleeve of band signal compensate function.
The utility model adopts following technical scheme:
A communication apparatus protective sleeve for band signal compensate function, protective sleeve is provided with slidably antenna, when skidding off this antenna from protective sleeve, the middle part of this antenna or end corresponding with the antenna of communication apparatus body.
Described communication apparatus is mobile phone, and protective sleeve is mobile phone protective cover, is provided with slidably antenna bottom mobile phone protective cover, when skidding off this antenna from protective sleeve, the middle part of this antenna or end corresponding in the antenna of mobile phone body.
Preferably, antenna is equipped with at the two ends of described mobile phone body, and the two ends bottom mobile phone protective cover respectively correspondence are provided with slidably antenna, and when skidding off two antennas from protective sleeve, the end of two slidably antennas is corresponding with the bottom of mobile phone body two antenna respectively.Not only be easy to operation, easy to use, two accepts simultaneously, and signal ability to accept is strong, decreases human body head hand radio frequency signal interference and causes signal weaker, and ensure that communication is carried out smoothly, applicability is strong.
Preferably, the shape of described slidably antenna is I shape, and acknowledge(ment) signal ability is strong.
Preferably, described slidably antenna embeds in protective sleeve, and antenna does not leak outside, and does not affect the attractive in appearance of appearance.
The beneficial effects of the utility model are: the utility model is according to the position of antenna in communication apparatus; as: the position that antenna for mobile phone is residing in mobile phone; a slidably duplex antenna is inserted in mobile phone protective cover or protective sleeve; in the bad border that movable signal is more weak; skid off the duplex antenna in protective sleeve; make the head of human body and the decay of hand to mobile phone radiofrequency signal be reduced to minimum, thus indirectly enhance the radiofrequency signal of mobile phone, thus ensure carrying out smoothly without letter communication.Skid off duplex antenna in the place that signal is weak and strengthen signal; in the strong place of signal without the need to duplex antenna; duplex antenna is slipped into mobile phone protective cover; esy to use, safe and reliable, mobile phone protective cover not only opponent's facility has defencive function; and there is the function of radio frequency signal compensation simultaneously, guarantee can normally use at the weak local mobile phone of signal or other communication apparatus.
Accompanying drawing explanation
Fig. 1. be the utility model structural representation;
Fig. 2. be the utility model Fig. 1 vertical view;
Fig. 3. be the structural representation that the utility model duplex antenna skids off;
Fig. 4. be the utility model Fig. 3 vertical view.
In figure: 1, mobile phone body; 2, the antenna of mobile phone body one end; 3, the antenna of the mobile phone body other end; 4, the top of slidably antenna; 5, the end of slidably antenna; 6, the end of another slidably antenna; 7, the top of another slidably antenna; 8, mobile phone protective cover.
Embodiment
As shown in Figure 1; the utility model provides a kind of communication apparatus protective sleeve of band signal compensate function; this protective sleeve is provided with slidably antenna; the shape of described slidably antenna is I shape; slidably antenna embeds in protective sleeve or inserts in protective sleeve; when skidding off this antenna from protective sleeve, the middle part of this antenna or end corresponding with the antenna of communication apparatus body.As: communication apparatus is mobile phone; protective sleeve is mobile phone protective cover 8; antenna is equipped with at the two ends of mobile phone body 1; two ends bottom mobile phone protective cover respectively correspondence are provided with slidably antenna; when skidding off two antennas from mobile phone protective cover 8, the end of two slidably antennas is corresponding with the bottom of mobile phone body 1 liang of antenna respectively.Acknowledge(ment) signal ability is strong.
Embodiment
When mobile phone is away from mobile base station or when the radio frequency signal of surrounding environment is more weak, skidded off by slidably antenna built-in in mobile phone protective cover 8, state as shown in Figure 1, 2 becomes the state shown in Fig. 3,4.When being in state shown in Fig. 4, mobile phone becomes external antenna from original built-in antenna, thus the head hand of human body weakening to become and minimumly even not have signal.The antenna 2 of mobile phone body one end and the antenna 3 of the mobile phone body other end send with the signal received directly to the end of slidably antenna built-in in mobile phone protective cover 8
5or the end 6 of another slidably antenna communicates; five external danger communications are completed again by the top 7 of the top 4 of slidably antenna that skids off in mobile phone protective cover 8 or another slidably antenna; thus decrease human body and hold mobile phone or antenna for mobile phone when head part, the hand of human body or the decay of head radio frequency signal.When close to communication base station or when believing better without letter, will slidably slide back in mobile phone protective cover 8 by antenna, mobile phone gets back to the state shown in Fig. 1,2 from the state shown in Fig. 3,4.
The utility model is not limited to above-mentioned preferred forms; anyone can draw other various forms of products under enlightenment of the present utility model; no matter but any change is done in its shape or structure; every have identical with the application or akin technical scheme, all drops within protection range of the present utility model.
