Method, system and device for determining sound quality of speaker

Abstract

The invention discloses a method, a system and a device for determining sound quality of a speaker. The determining method comprises the following steps: S1, acquiring a pink noise signal of a standard sound pressure level transmitted by the signal generator to the speaker to be tested; S2, transmitting the pink noise signal to the audio analyzer to obtain a level value corresponding to the pink noise signal; S3, acquiring a specific test signal of a standard sound pressure level transmitted by the signal generator to the speaker to be tested; S4, transmitting the specific test signal to the audio analyzer to obtain a level value corresponding to the specific test signal; and S5, setting the level value of the pink noise signal as a reference value, and comparing the level value of the specific test signal with the reference value to identify the sound quality of the speaker. The technical solution of the invention is capable of effectively identifying the sound quality of the speaker,and effectively reducing the test errors.

Description

technical field [0001] The invention relates to the technical field of sound boxes, in particular to a method, system and device for judging sound quality of sound boxes. Background technique [0002] Speaker refers to a device that can convert audio signals into sound. In layman's terms, it refers to the power amplifier in the main box of the speaker or the subwoofer box. After the audio signal is amplified, the sound is played back by the speaker itself. The sound gets louder. [0003] At present, the development of speaker performance mostly focuses on the heat dissipation performance, noise reduction performance and sound quality improvement of the speaker, for example: [0004] The invention patent with the application number 201510899905.1 discloses a speaker that can improve the sound quality of the bass. The speaker includes: a support with an inverted T-shaped cross section; The loudspeaker located at the front end of the box; and the wave absorber located at the ...

Problems solved by technology

[0006] However, the test of the sound quality performance of speakers is often judged subjectively by the human ear, and it is inevitable that there will be test errors caused by the subjective judgment of the human ear; secondly, when testing multiple speakers Test errors are often caused by differences in sensitivity; and the existing judgments on the sound quality of speakers often use a single frequency point as a reference, and the resulting EQ curve is not flat and easily causes test errors
