Embodiment 1

[0020] see figure 1 Shown, a kind of earphone sound quality detection method comprises the following steps:

[0021] S11 receives the sound signal from the earphone;

[0022] S12 converts the sound signal into a corresponding audio frequency spectrum;

[0023] S13 performs matching analysis on the audio spectrum and preset audio spectrums of different levels, and determines the level of the audio spectrum according to the result of the matching analysis;

[0024] S14 Determine the sound quality level of the earphone according to the level of the audio frequency spectrum.

[0025] The specific content of this embodiment will be described in detail below. First, receive the sound signal sent by the earphone, preferably, the sound signal sent by the earphone is the audio signal of the test song; secondly, convert the sound signal sent by the earphone into a corresponding audio frequency spectrum, which contains the audio frequency spectrum that can reflect the sound quality of...

Embodiment 2

[0029] In another embodiment, the sound signal includes a left sound signal emitted by the left channel of the earphone and a right sound signal emitted by the right channel of the earphone, see figure 2 Shown, this embodiment comprises the following steps:

[0030] S20 receives the left audio signal from the left channel of the earphone;

[0031] S21 receives the right sound signal from the right channel of the earphone;

[0032] S22 converts the left sound signal and the right sound signal into corresponding left audio frequency spectrum and right audio frequency spectrum respectively;

[0033] S23 performs matching analysis on the left audio frequency spectrum and the right audio frequency spectrum respectively with preset audio frequency spectrums of different levels, and determines the levels of the left audio frequency spectrum and the right audio frequency spectrum according to the result of the matching analysis, and the level is consistent with the sound quality of ...

Embodiment 3

[0038] Simultaneously, the present invention proposes a kind of headphone sound quality detection system, see image 3 , the system consists of:

[0039] Microphone unit 31, for receiving the sound signal that earphone sends;

[0040]A digital spectrum conversion unit 32, configured to convert the sound signal into a corresponding audio frequency spectrum;

[0041] The determining unit 33 is configured to perform matching analysis on the audio spectrum and preset audio spectrums of different levels, and determine the level of the audio spectrum according to the result of the matching analysis, and the level of the audio spectrum corresponds to the sound quality level of the earphone.

[0042] Specifically, first, the microphone unit 31 receives the sound signal sent by the earphone. Preferably, the sound signal sent by the earphone is the audio signal of the test song. Taking a mobile phone as an example, the main microphone or the secondary microphone of the mobile phone can...

Abstract

The invention relates to a method, a system and a terminal for detecting the tone quality of earphones, wherein the method comprises the following steps: receiving acoustical signals sent by the earphones; converting the acoustical signals into a corresponding audio spectrum; and analyzing the audio spectrum with pre-set audio spectrums of different grades in a matched manner, and judging the grade of the audio spectrum according to a matched analysis result, wherein the grade of the audio spectrum corresponds to the tone quality grade of the earphones. According to the method for detecting the tone quality of the earphones, the tone quality of the earphones can be detected conveniently and rapidly; furthermore, the method is independent of other extra professional equipment; therefore, the method has high practicability and high use value; and simultaneously, the method for detecting the tone quality of the earphones can be applicable to the system and the terminal including the system.

Description

technical field [0001] The invention relates to the field of sound quality detection of sound signals, in particular to a method, system and terminal for sound quality detection of earphones. Background technique [0002] With the popularity of mobile terminals such as smart phones and the continuous improvement of people's pursuit of quality of life, people pay more and more attention to the quality of sound information obtained from mobile terminals. Earphones are indispensable mobile terminal accessories in people's daily life. The use of earphones greatly facilitates people to obtain sound information such as music and calls from mobile terminals. Very important influence. Under normal circumstances, only professionals can identify the sound quality of headphones with the help of professional audio equipment, while it is difficult for ordinary people to judge the sound quality of headphones objectively and quickly. Contents of the invention [0003] Based on this, it...
