Description
Technical field
The utility model relates to a kind of testing equipment of efficient detection IP phone audio performance.
Background technology
Main outgoing and the consistency of leaning on subjective listen test or electroacoustical measurement instrument to ensure phone in black phone production process, the voice quality of IP phone is far above black phone, and subjective testing is difficult to ensure consistency, the deployment complexity of IP phone.The voice quality of IP phone is on the one hand by subjective judgement, on the one hand by professional tone testing testing equipment at present.In addition, some companies have proposed new method of testing because of the defect of above-mentioned two kinds of methods:
(1), IP phone is registered on sip server, set up call by software terminal and IP phone, by network, test signal is sent to tested phone, then use artificial ear pick up the audio frequency that tested phone loudspeaker play and analyze, judge the audio-frequency index such as hands-free broadcasting frequency response, loudness, the distortion factor of tested phone.To play test signal by artificial mouth to the test sending, the voice signal receiving is sent to soft phone by tested phone, analysis tool intercepts tested phone issues the packet of soft phone, parse audio signal analysis, judge the audio-frequency indexes such as the frequency response, loudness, the distortion factor of the transmission of tested phone.
(2), two IP phone are registered on server, and the handle interface of two IP phone is linked into audio-frequency test instrument, and set up call.Audio-frequency test instrument is play test signal, the microphone of IP phone A is sent to IP phone B after picking up signal, then pass to audio-frequency test instrument by the handle interface of IP phone B again, audio-frequency test instrument is analyzed according to the test signal of playing and the audio signal receiving after phone A and phone B, judges the transmission of IP phone and accepts the voice quality of path.
Two schemes above-mentioned, all needs connected with network cable, and is registered on sip server, sets up call aptitude test, and test operation is loaded down with trivial details, and efficiency is extremely low, has a strong impact on production efficiency.And special IP phone audio-frequency test equipment, high to environmental requirement, equipment investment cost is high, is producing line deployment difficulty.Present patent application file has proposed a kind of quick testing equipment of IP phone voice quality, can in batch production process, measure detection to the voice quality of IP phone more efficiently.
Wherein, spectrum analysis: spectrum analysis is exactly that the acoustic pressure, phase place of analyzing audio signal are with the relation of frequency change; The audio frequency acoustic pressure that the audio signal that microphone receives and loudspeaker are play can occur to increase or decay with the variation of frequency, and phase place also can change; Carry out spectrum analysis and can judge whether the loudness under different frequency of microphone, loudspeaker meets the requirements.
The distortion factor: what the distortion factor represented is the degree that signal departs from pure sinusoid signal; When distortion appears in microphone or loudspeaker, there will be the harmonic component not having in former audio signal, cause the variation of tone color, even can distorsion when serious, ear-piercing etc.;
SIP:SIP is the abbreviation of Session Initiation Protocol, is the signaling control protocol of an application layer.For creating, revise and discharge one or more participants' session.These sessions can be Internet multimedia conferencing, IP phone or multimedia delivery.The participant of session can communicate by multicast (multicast), netted clean culture (unicast) or both mixtures.
SIP phone: the IP phone of supporting Session Initiation Protocol.
