The invention discloses a test program and system for high-fidelity audio equipment. The device comprises a test box and control equipment, the inner wall of the test box is fixedly connected with first sound absorption cotton; A box cover is clamped to the top of the test box, second sound absorption cotton is fixedly connected to the inner surface of the box cover, audio equipment is movably connected to the bottom of an inner cavity of the first sound absorption cotton, a data line penetrates through the bottom of the right wall of the test box, and the left end of the data line is clampedto the right side of the audio equipment through a plug. The invention discloses a test program and system for high-fidelity audio equipment. First sound absorption cotton and second sound absorptioncotton are arranged on the inner surfaces of a test box and a box cover respectively; When audio equipment plays sound, sound waves can be absorbed, the situation that echo is formed in a closed space, and consequently the testing accuracy is affected is avoided, the audio equipment is inserted into the testing box for testing, the testing is not affected by the external environment, and operationis easy and convenient.
Description
technical field [0001] The invention relates to the technical field of test systems, in particular to a test program and system for high-fidelity audio equipment. Background technique [0002] Audio equipment is mainly a general term for audio input and output equipment, and it includes many types of products, which can generally be divided into the following categories: power amplifiers, speakers, multimedia consoles, digital mixers, audio sampling cards, synthesizers, mid-high Audio speakers, microphones, sound cards in PCs, headphones, etc. Sound quality is an important criterion for judging the quality of audio equipment, including indicators such as signal-to-noise ratio, number of sampling bits, sampling frequency, and total harmonic distortion. The level of these parameters determines the sound quality of audio equipment. The device type refers to the type of audio device, that is, which type of audio device belongs to power amplifier, speaker, multimedia console, di...
