Hand-free tone quality testing system of IP (internet protocol) phone terminal device and method thereof

Abstract

The invention relates to a hand-free tone quality testing system of an IP (internet protocol) phone terminal device, which comprises a main testing unit. Standard sound sources are stored in the main testing unit, the main testing unit is connected and disposed on to-be-tested IP phone terminal equipment in a soundproof box through netting cables and is connected with a standard loudspeaker and a standard microphone through audio cables, wherein the standard loudspeaker and the standard microphone are disposed in the soundproof box. The invention further relates to an IP phone terminal device hand-free tone quality testing method on the basis of the hand-free tone quality testing system, which includes steps of playing the standard sound sources through the loudspeaker of the to-be-tested IP phone terminal equipment, analyzing sound received by the standard microphone to detect the loudspeaker of the IP phone terminal equipment, playing the standard sound sources through the standard loudspeaker, analyzing sound received by the microphone of the IP phone terminal equipment to detect the microphone of the IP phone terminal equipment, and accordingly, testing of sound quality of the IP phone terminal equipment is realized. The hand-free sound quality testing system is simple in structure, low in manufacturing cost, excellent in universality, simple and convenient in testing method and better in testing effect.

Description

technical field [0001] The invention relates to the technical field of IP telephones, in particular to the technical field of detection of IP telephone terminal devices, in particular to a hands-free sound quality testing system and method for an IP telephone terminal device. Background technique [0002] With the rapid development of optical networks and the application of digital transmission technology, data services based on IP services have developed rapidly, IP phones have been widely developed and used, and users have put forward higher requirements for sound quality of IP phones. An IP phone that can provide features such as functional safety, stability, and hands-free conference calls is required, so the hands-free sound quality of the IP phone needs to be further tested during the production test of the IP phone. [0003] At present, many companies in the industry have introduced several common hands-free sound quality testing methods for IP phones. SUNLIGHT, B&K,...

AI Technical Summary

Problems solved by technology

However, the test equipment introduced by these companies is a dedicated sound quality test equipment, which is relatively complex and expensive, and has poor versatility for different IP phone terminals. Usually, it can only be used for audio testing of a single IP phone terminal. This restricts the further development and progress of IP telephony technology
