The device of the detection of handset performance that the utility model provided, but the performance of the anti-radio frequency interference of detection of handset have been filled up the deficiency of this technical field on this direction.
Description of drawings
Fig. 1 is the structural representation of the device of the described detection of handset performance of the utility model embodiment.
Embodiment
For the purpose, technical scheme and the advantage that make the utility model embodiment clearer; To combine the accompanying drawing among the utility model embodiment below; Technical scheme among the utility model embodiment is carried out clear, intactly description; Obviously, described embodiment is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1, present embodiment provides a kind of device of detection of handset performance, comprising:
Signal takes place and detector 102, is used for establishing a communications link with mobile phone, and the samples played voice signal receives the voice signal of feedback and does comparison with the sample voice signal of playing;
Said mobile phone pedestal 101 is provided with:
Anti-radio frequency interference microphone 1011 is used to receive the sound that the receiver from mobile phone to be measured spreads out of, and transfers to signal and take place and detector 102;
Anti-radio frequency interference loudspeaker 1012 are used to receive from the voice signal of signal generation with detector 102, and play to the microphone of mobile phone to be measured.
Further, said signal takes place and detector 102, comprising:
Mobile phone signal takes place and receiving circuit 1021, is used under control circuit 1022 controls, establishing a communications link with mobile phone to be measured;
Control circuit 1022; Be used to receive voice signal from anti-radio frequency interference microphone 1011; Send voice signal from multimedia process chip 1023 in anti-radio frequency interference loudspeaker 1012, send to multimedia process chip 1023 to the voice signal that receives and do contrast and handle;
Multimedia process chip 1023, the voice signal that control and treatment circuit 1022 sends, the voice signal that comparative analysis is received sends to the distortion situation of the voice signal of control circuit 1022 relatively.
It will be appreciated by those skilled in the art that; Radio frequency interference is mainly reflected in the receiver of mobile phone and the interference at microphone position the influence of mobile phone call performance; So, can obtain the performance parameter of the interference of mobile phone antagonism radio frequency to be measured through to the receiver of mobile phone and the anti-radio frequency interference performance detection of microphone part.Through signal take place with detector send have voice signal signal of communication in mobile phone to be measured; Anti-radio frequency interference microphone receives the voice signal that the receiver from mobile phone sends; The received voice signal of contrast microphone takes place with original signal and the distortion situation of the voice signal that detector sends through signal of communication; Distortion parameter contrast standard parameter, promptly can obtain detecting the anti-radio frequency interference performance parameter of earpiece to be measured.Through signal take place with detector 102 controls by anti-radio frequency interference loudspeaker 1012 signal that plays sound; The microphone of mobile phone to be measured receives voice signal and sends to signal through mobile phone and takes place and detector 102; The signal of communication of mobile phone takes place to receive with detector 102 in signal; The voice signal in the signal of communication that contrast receives and the parameter distortion situation of former anti-radio frequency interference loudspeaker played sound signal; Distortion parameter contrast standard parameter, promptly can obtain the anti-radio frequency interference performance parameter of mobile phone microphone to be measured.The parameter of estimating the audio distortions situation has signal to noise ratio etc., for conventionally known to one of skill in the art, repeats no more here.
Further; Also comprise mobile communication signal shielding case 103; Said mobile phone pedestal 101 is arranged on the inside of said mobile communication signal shielding case 103, can guarantee that like this inside of said mobile communication signal shielding case 103 takes place all to be arranged on detector 102, anti-radio frequency interference microphone 1011, anti-radio frequency interference loudspeaker 1012 and mobile phone to be measured said signal.It will be understood by those skilled in the art that when communication environment is relatively poor in order to guarantee communicating by letter between mobile phone and the base station, mobile phone can increase the operating power of its radio-frequency module.Be utilized in outer handset to be measured in the present embodiment said mobile communication signal shielding case 103 is set, simulate relatively poor communication environment,, be convenient to handset capability is detected to increase the operating power of mobile phone radio frequency module to be measured.
It will be understood by those skilled in the art that any mobile phone all can have the demonstration of signal lattice number, if signal lattice number for the highest, explains that so present signal is relatively good.Mobile phone is used minimum transmitting power and the other side conversation in conversation.Be not easy to find the situation of radio frequency interference receiver and microphone in this case.When signal lattice number when being minimum, maximum power used by mobile phone and the base station connects, and carries out communication with maximum power.This time, radio frequency interference was maximum.So, reduce the effect that mobile phone signal lattice number can amplify the anti-radio frequency interference test of mobile phone through the masked segment mobile phone signal.
Further, the device of said detection of handset performance also comprises: radio frequency interference generator 104 is used for further increasing the radio frequency interference to the receiver and the microphone of mobile phone to be measured.
So just realize artificial amplification radio frequency interference, reached the purpose of the effect that improves the anti-radio frequency interference test of mobile phone.It will be understood by those skilled in the art that there is radio frequency interference in occurring in nature, but the intensity of radio frequency interference is very low,, can reaches the purpose of the effect that improves the anti-radio frequency interference test of mobile phone through the radio frequency interference in the artificial increase test environment.
Further, said radio frequency interference generator 104 places in the said shielded box, to increase the effect of radio frequency interference.
What should explain at last is: above embodiment is only in order to the technical scheme of explanation the utility model, but not to its restriction; Although the utility model has been carried out detailed explanation with reference to previous embodiment; Those of ordinary skill in the art is to be understood that: it still can be made amendment to the technical scheme that aforementioned each embodiment put down in writing, and perhaps part technical characterictic wherein is equal to replacement; And these are revised or replacement, do not make the spirit and the scope of each embodiment technical scheme of essence disengaging the utility model of relevant art scheme.
