For TWS earphone products, it is generally realized by software driving the hardware to output a signal of a certain power to make the speaker diaphragm vibrate continuously.

However, because the aging process is often long, the system has a large load, and the process is more complicated, some machines with unstable performance may have some abnormalities in structural assembly, electronic devices, and acoustic devices during the aging process.

2, the first embodiment of the earphone detection method of the present invention, the earphone detection method includes:

Step S10, playing the preset test data through the sound generating device of the earphone to output the acoustic signal;

In this embodiment, the main body of implementation is the earphone aging system (or the earphone aging management module, etc.). The earphone aging system refers to a system that controls the earphone to play specific audio data to accelerate the aging and stability of the earphone, so that the device quickly enters the mature stage. . After the earphone aging system ages the earphones, the earphone aging system plays the preset test data through the sound-generating device (such as a speaker, a speaker, etc.) of the earphone, so that the sound-generating device outputs an acoustic signal (causing air vibration).

Step S20, collecting the acoustic signal through the microphone of the earphone to obtain the audio data to be detected of the earphone;

Specifically, the above-mentioned earphones refer to earphones with built-in microphones, such as active noise reduction earphones. Active noise-cancelling headphones are usually composed of a main microphone for talking, a feed-forward microphone for detecting the external environment, a feed-back microphone for detecting noise residuals, and a speaker. The above-mentioned sounding device is the speaker of the active noise reduction earphone. It can be understood that the main microphone, the feed-forward microphone and the feed-back microphone of the active noise reduction headset can all collect the acoustic signal output by the sound-generating device, wherein the feed-back microphone is relatively close to the sound-generating device (speaker) (or is located at the end of the sound-generating device). sounding direction), the acoustic signal output by the sounding device can be received relatively clearly. Therefore, in this embodiment, the feedback microphone is preferentially used to collect the acoustic signal. The earphone microphone can collect the sound emitted by the earphone sounding device based on the preset test data, and convert the collected sound into an electrical signal, which is the audio data to be detected.

Further, before the step of playing the preset test data through the sounding device of the earphone to output the acoustic signal, the method further includes: playing pink noise data through the sounding device to speed up the aging and stabilization of the earphone device.

Specifically, the earphone aging system will also input the pink noise data to the earphone, and the earphone will sound based on the received pink noise data. When the pink noise data is played by the earphone, the aging of the earphone can be accelerated and the earphone components can be stabilized. This process also Known as "burning in". Therefore, the actual playback content of the headphones can be a loop of pink noise data followed by a section of test data, or, when the earphone aging process is about to end, the preset test data is played, and before that, all pink noise is played. data. The preset test data is used to check whether the headset is abnormal, and the preset test data usually selects a relatively regular audio signal, such as a 1KHz single-frequency signal. It is understandable that a relatively regular audio signal can facilitate the subsequent analysis of the abnormality of the headset. The earphone aging system will play the pink noise data and the preset test data through the sound device of the earphone, and also collect the audio data generated by the sound device to actually play the pink noise data and the preset test data through the microphone of the earphone. At this time, the audio data collected by the microphone includes pink noise data and preset test data, and the part of the collected audio data that plays the preset test data will be used as the audio data to be detected.

It can be understood that, in this embodiment, the earphone aging system uses the built-in microphone of the earphone to collect the audio data from the earphone sounding device, and uses the collected audio data for analysis and detection of the playback quality of the earphone. Compared with the current use of professional audio The analysis equipment detects the earphones. The solution of this embodiment does not require additional analysis equipment, reduces the production cost, and does not need to wait for the professional audio analysis equipment to be idle, and realizes the simultaneous detection of multiple or multiple pairs of earphones. In addition, the preset detection data will be input to the headphone playback together with the pink noise data, so that the headphones involved in the aging can be synchronously tested for the playback quality, and the quality detection can be performed simultaneously when the headphones are aging, which improves the detection efficiency of the headphones and the delivery efficiency. .

Step S30, compare and analyze the audio data to be detected and the preset test data to generate a detection result of the earphone.

Specifically, when the headset only plays the preset test data, the audio data collected by the headset microphone is generated based on the preset test data. Therefore, the audio data can be directly used as the audio data to be detected and the preset test data. Comparative analysis. When the earphone aging system outputs preset comprehensive data (including pink noise data and preset test data) to the headset, the audio data collected by the headset microphone will be generated based on the pink noise data and the preset test data. Therefore, when the earphone aging system outputs the preset test data to the earphone, the earphone aging system can turn on the earphone microphone to collect the acoustic signal generated by the earphone playback device. The audio data collected at this time is used as the audio data to be detected, and the audio data to be detected is compared and analyzed. It can be understood that the audio data to be detected is the audio data of the headset microphone playing the preset test data, and the preset test data used for comparative analysis is the original preset test data. Compare and analyze the original preset test data and the audio data to be detected. Based on the difference or degree of difference between the two, the playback quality of the headphones can be judged (the bigger the difference, the worse the playback quality, and the smaller the difference, the worse the playback quality. The better the quality), the detection result of the headset is generated according to the playback quality of the headset.

Further, the audio data to be detected is filtered based on the preset test data to generate a cumulative distortion amount; the detection result of the earphone is generated according to the cumulative distortion amount.

Specifically, as shown in FIG. 4 , it is the signal spectrum of the audio data to be detected, the abscissa of the signal spectrum is the amplitude, and the ordinate is the frequency. The audio data to be detected includes the fundamental wave, the 2nd harmonic, the 3rd harmonic, and the 4th harmonic. Among them, the fundamental wave corresponds to the frequency F, the 2nd harmonic corresponds to the frequency 2F, and the 3rd harmonic corresponds to the frequency 3F and the 4th harmonic. Harmonics correspond to 4F and, in addition, will include noise (the frequency of noise is usually random). In the detection process, the fundamental wave is the above-mentioned preset test data, such as a 1KHz fundamental wave signal. The 2nd harmonic, 3rd harmonic, 4th harmonic and noise are all factors that affect the playback quality of headphones, and are also used to measure the degree of ear distortion. The audio data to be detected will be filtered based on the preset test data (1KHz fundamental wave signal), that is, the fundamental wave in the audio data to be detected will be filtered out, and the 2nd harmonic, 3rd harmonic, 4th harmonic and noise will remain. , as shown in FIG. 5 , is the signal spectrum of the audio data to be detected after filtering, the abscissa of the signal spectrum is the amplitude, and the ordinate is the frequency. Calculate the cumulative energy of the 2nd harmonic, 3rd harmonic, 4th harmonic and noise to obtain the cumulative amount of distortion. According to the cumulative amount of distortion, it is judged whether there is an abnormality in the earphone, and the corresponding detection result is generated. Or perform THD+N (Total Hormonic Distortion+Noise, total harmonic distortion plus noise) calculation and analysis on the audio data to be detected, generate the distortion degree of the earphone, and generate a corresponding detection result based on the distortion degree.

Further, when the cumulative amount of distortion is greater than the preset distortion threshold, the test result of the earphone is a defective product; when the cumulative amount of distortion is less than or equal to the preset distortion threshold, the test result of the earphone is: Good product.

Specifically, the cumulative amount of distortion is compared with the preset distortion threshold. If the cumulative amount of distortion is greater than the preset distortion threshold, the earphone is determined to be defective, and the corresponding detection result of the earphone is defective. If the cumulative amount of distortion is less than or equal to the preset value The distortion threshold determines that the earphone is a good product. The specific preset distortion threshold can be set by a technician according to the actual factory standard of the earphone.

In this embodiment, the preset test data is played by the sound generating device of the earphone to output the acoustic signal; the acoustic signal is collected by the microphone of the earphone to obtain the audio data to be detected of the earphone; the audio data to be detected is acquired Compare and analyze with the preset test data to generate the detection result of the earphone. That is, the earphone aging system uses the built-in microphone of the earphone to collect the earphone sounding device to generate audio data, and uses the collected audio data for the analysis and detection of the earphone playback quality. Compared with the current professional audio analysis equipment to detect the earphone, this embodiment The solution does not require additional analysis equipment, reduces production costs, and does not need to wait for professional audio analysis equipment to be idle, enabling simultaneous detection of multiple or multiple pairs of headphones.

Referring to FIG. 3, the second embodiment of the earphone detection method of the present invention, the earphone detection method includes:

Step S100, playing pink noise data through the sounding device to speed up the aging and stabilization of the earphone device;

Specifically, the earphone aging system will play the pink noise data through the sound device of the earphone, so that the vibration device of the earphone will quickly run in when playing the pink noise data device, thereby accelerating the aging of the vibration device and making it more stable, thereby ensuring the playback effect of the earphone. .

Step S200, playing the preset test data through the sound generating device of the earphone to output the acoustic signal;

Further, before the step of playing the preset test data through the earphone sounding device to output the acoustic signal, the method further includes: inserting mute data between the pink noise data and the preset test data to The sound generating device is made to play in the order of pink noise data, mute data and preset test data.

Specifically, in this embodiment, mute data is also inserted between the pink noise data and the preset test data, that is, the earphone aging system will play the pink noise data, the preset test data, and the mute data in sequence through the sound generating device of the earphone . Figure 6 is a schematic diagram of the sequence of audio data, and the proportion of various types of data can be set by the technician according to the actual situation. Usually, the proportion of pink noise data is more, and the proportion of mute data is less. It is understandable that it takes a long time for the earphone to age. The earphone aging system can play the pink noise data, the preset test data and the mute data in a loop to increase the time for the earphone to play the pink noise data. A test will be performed.

Step S300, collecting the acoustic signal through the microphone of the earphone to obtain the audio data to be detected of the earphone;

Specifically, at this time, the acoustic signal generated by the sound generating device of the earphone will include the acoustic signal generated by playing pink noise data, mute data and preset test data, and the acoustic signal used for earphone detection to play the part of the preset test data.

Further, when the mute data is played by the sounding device, start and collect the acoustic signal output by the sounding device through the microphone to generate audio data; use the audio data collected and generated within a preset time period as the Audio data to be detected.

Specifically, after the earphone aging system controls the current sounding device of the earphone to play the mute data, the earphone aging system starts the collection of audio data of the earphone microphone, and uses the data collected within a preset time period as the audio data to be detected. The preset time period may be the same as the playing time of each preset test data, so as to ensure that the acquired audio data to be detected is generated when the sound generating device plays the preset test data. That is, mute data is used for pink noise data and excessive preset detection data, as well as a prompt to start collecting audio data to be detected.

Step S400, compare and analyze the audio data to be detected and the preset test data to generate a detection result of the earphone.

Further, the audio data to be detected is filtered based on the preset test data to generate a cumulative distortion amount; the detection result of the earphone is generated according to the cumulative distortion amount.

Further, when the cumulative amount of distortion is greater than a preset distortion threshold, the test result of the earphone is determined to be a defective product; when the cumulative amount of distortion is less than or equal to the preset distortion threshold, the test of the earphone is determined. The result is good.

Further, after the step of generating the detection result of the earphone, the method includes: when the detection result of the earphone is a defective product, stopping the sounding device from playing the pink noise data, and outputting the A message indicating that the headset is a defective product.

Specifically, when it is determined that the earphone is a defective product, the earphone aging system will stop sending pink noise data to the earphone, that is, stop the aging process of the earphone, and correspondingly output a prompt message that the earphone is a defective product.

In addition, it should be noted that the detailed process of the steps in this embodiment that are the same as those in the first embodiment may refer to the first embodiment, which will not be repeated here.

In this embodiment, the earphone aging system can cyclically play pink noise data, mute data and preset test data, and the earphone aging system will check the playback quality of the earphones after each aging of the earphones, so as to realize all participants in the aging process. Real-time detection of processed headphones during the aging process. Moreover, compared with the current method of detecting the earphones with professional audio analysis equipment after the earphones are aging, the earphone aging system in this embodiment can detect the playback quality of the earphones during the aging process of the earphones. After it is determined that the earphone is a defective product, the aging of the earphone can be stopped, thereby avoiding unnecessary aging treatment of the defective earphone and increasing the overall production efficiency.

In addition, an embodiment of the present invention also provides an earphone detection device, where the earphone detection device includes:

The aging management module 1 performs data communication with the aging signal output module 3 and the signal analysis module 4 through the message distribution module 2 respectively. During the aging process of the earphones, the aging process control 1-1 sends an instruction (which may include the number of cycles) to turn on the output to the aging signal output module 3 through the message distribution module 2, and the aging signal output module 3 starts after receiving the command to turn on the output.
