Testing principle of the present invention basis is: utilize the test philosophy in one one sound loop of receiving, adopt the method for testing of a plurality of unifrequency source of sound successive tests.By standard horn send the standard source of sound, through treating the frequency and the loudness analysis of the sound that the scaffold tower microphone receives, thereby judge the good and bad of the microphone function of treating scaffold tower.Control make the loudspeaker of treating scaffold tower send the standard source of sound, through the frequency and the loudness analysis of sound that standard microphone is received, judge the good and bad of the horn function of treating scaffold tower.Certainly, the detection order of treating scaffold tower microphone and loudspeaker can be changed.
The hands-free method of testing of IP phone of the present invention, as shown in Figure 3, comprise the steps:
1, initial setting up before the test: treat that by producing the survey software control scaffold tower is under the hands-free mode.
2, microphone test: survey the software control test computer and play the standard source of sound of a fixed frequency and loudness (such as 1KHZ, 20dB) by producing; Make standard horn sounding in sound proof box through data wire; The microphone of treating scaffold tower receives; Test computer will treat that the signal that scaffold tower receives reads back its frequency of judgement and loudness, can judge SFR and SLR.Wherein, SLR=Lg (signal that standard pronunciation source signal/microphone receives), SFR is appeared by the frequency of treating the signal that the scaffold tower microphone is received.
3, loudspeaker test: survey software control and let the loudspeaker of treating scaffold tower play the standard pronunciation source signal (such as 1KHZ, 20dB) of a fixed frequency and loudness by producing; Receive through standard microphone; Pass to test computer through sound source wire; Sound by product survey software receives standard microphone is judged its frequency and loudness, can judge RFR and RLR.Wherein, RLR=Lg (standard signal/treat the audio signal that the scaffold tower loudspeaker send), the frequency of the signal that the loudspeaker of treating scaffold tower that RFR is received by standard microphone send appears.
4, be the frequency range that the performance characteristics of wideband or narrow frequency is judged its test according to product: for example tested 1KHZ according to aforesaid way, same principle can be tested other Frequency point, like 2KHZ, 3KHZ etc.Finally, according to the frequency of the sound of each Frequency point and the test of loudness, thereby accomplish the test of the sound quality under the hands-free mode.
In the present invention, the microphone that is adopted when testing the loudspeaker of treating scaffold tower is a standard microphone, and the loudspeaker that adopted when testing the microphone of treating scaffold tower are standard horns.Standard microphone and standard horn are meant that through its performance of laboratory proofing be stable equipment.What play is the standard source of sound, and the distance of loudspeaker and microphone is fixed, and treats that scaffold tower fixes in the position of sound proof box.Therefore when function of test, have only parameter of test item, other condition all is objective.Therefore, adopt the test result of the hands-free acoustical testing system and method for IP phone of the present invention more accurate, the test better effects if.
IP phone terminal equipment hands-free acoustical testing system of the present invention and method thereof have been adopted; Because its system comprises the Test Host that stores the standard source of sound; This Test Host is positioned over the IP phone terminal equipment to be measured in the sound proof box through the netting twine connection, and this Test Host also connects a standard horn and standard microphone that all is positioned in the described sound proof box respectively through tone frequency channel wire.Thereby can utilize this Test Host through IP phone terminal equipment loudspeaker playing standard source of sound to be measured; The sound that receives of analytical standard microphone detects the loudspeaker of IP phone terminal equipment then; This Test Host also capable of using is through standard horn playing standard source of sound; The sound that receives of the microphone of analyzing IP telephone terminal detects the microphone of IP phone terminal equipment then, to accomplish the test to IP phone terminal equipment tonequality.IP phone terminal equipment hands-free acoustical testing system of the present invention and method thereof, its system configuration is simple, and is cheap for manufacturing cost; The audio quality that can be applied to multiple IP phone terminal equipment detects; Versatility is preferable, and its test mode execution mode is easy, and the test effect is better.
In this specification, the present invention is described with reference to its certain embodiments.But, still can make various modifications and conversion obviously and not deviate from the spirit and scope of the present invention.Therefore, specification and accompanying drawing are regarded in an illustrative, rather than a restrictive.
