Problems solved by technology

[0004] However, microphones and speakers will inevitably be damaged during packaging and transportation. This damage occurs after the integrated inspection, and the damage is concealed to a certain extent. It is generally difficult to distinguish, and it is difficult to be detected during the earphone assembly process ( Even if there is a factory inspection of the finished headset, it will not pay attention to the damage of the microphone and speaker), therefore, it is easy to misuse the damaged microphone and speaker during the assembly process of the headset, resulting in a decline in the quality of the headset and seriously affecting the user experience

Embodiment Construction

[0039] In order to describe the technical content, structural features, achieved goals and effects of the present invention in detail, the following will be described in detail in conjunction with the embodiments and accompanying drawings.

[0040] see figure 1 As shown, the audio component selection method of this embodiment is suitable for quality control of the audio component to be tested, and the audio component to be tested is specifically a microphone or a speaker. The audio file selection method of the present embodiment comprises the following steps:

[0041] S1. Send out a simulated sound wave. The simulation sound wave is sent by the simulation sound source, and the simulation sound source can adjust the frequency parameter and the decibel parameter to send out a sound wave with a preset frequency and a preset decibel sound to meet the test requirements, and the simulation sound wave is used as a standard in this embodiment Sound source for subsequent test compari...

Abstract

The invention discloses a method for selecting an audio component, which comprises the following steps: sending out a simulated sound wave; receiving the simulated sound wave by the audio component to be tested, and generating a test sound wave according to the simulated sound wave; analyzing the simulated sound wave and the test sound wave, according to The first frequency response curve is obtained by the simulated sound wave, and the second frequency response curve is obtained according to the test sound wave; the test frequency value shared by at least two of the first frequency response curve and the second frequency response curve is selected, and according to the test The frequency values ​​respectively obtain the first decibel value corresponding to the first frequency response curve and the second decibel value corresponding to the second frequency response curve; judge whether the first difference between the first decibel value and the corresponding second decibel value falls within Enter the preset first sensitivity deviation interval, and analyze the sensitivity of the audio component to be tested according to the judgment result; the invention can directly control the sensitivity quality of the audio component, and analyze the sensitivity of different audio components; the invention also discloses a An audio file selection device.

Description

technical field [0001] The invention relates to the technical field of sound quality detection, in particular to an audio component selection method and an audio component selection device. Background technique [0002] The core components of the headset include a microphone and a speaker. The quality of the microphone and speaker is very important, and their sensitivity and responsiveness directly affect the quality of the headset. Specifically, the microphone is mainly used for sound collection of earphones, especially for active noise-cancelling earphones, the cooperation between the microphone and various components requires extraordinary sensitivity and responsivity, in order to record call sounds and collect noises (such as collecting environmental noises for noise reduction). noise processing). The speaker is mainly used to convert the audio signal processed by the noise reduction algorithm into a sound wave and spread it to the outside. The quality of the speaker di...
