In addition, referring to fig. 6, in a first embodiment of the audio output control method, the audio output control method is applied to the head display device, where the wired earphone includes an earphone cord, an earphone head and a cord reel, the head display device includes a head display body and a wired earphone, and the audio output control method includes the following steps:

step S10, acquiring first position and posture information of the head display body and second position and posture information of the earphone head;

in this embodiment, the head display device may be, for example, a Mixed Reality (Mixed Reality) -MR device, an Augmented Reality (Augmented Reality) -AR device, a virtual Reality- (virtual Reality) -VR device, an Extended Reality (Extended Reality) -XR device, or some combination thereof.

Step S30, according to the wearing pose change information, judging whether the equalizer parameter of the wired earphone needs to be adjusted;

in particular, the equalizer parameters refer to adjustment parameters of the equalizer. Through the wearing pose change information, the wearing pose change condition of the earphone head relative to a wearer can be determined, if the wearing pose change is large, the earphone fitting degree between the earphone head and the auditory canal of the user is changed, and then the tone quality effect of the earphone head is possibly influenced, and the equalizer parameters need to be adjusted again. Therefore, the corresponding pose change threshold value can be set in advance. And then judging whether to adjust equalizer parameters according to the wearing pose change information and the pose change threshold. The pose change threshold value may be set by a person skilled in the art according to an actual situation, and the embodiment is not particularly limited.

Step S40, if the equalizer parameters need to be adjusted, a preset adjustment operation is performed on the equalizer parameters.

Specifically, the preset adjustment operation may include a degree of fitting detection and an equalizer parameter adjustment. If the current equalizer parameter is adjusted, a preset fitting degree detection operation can be executed to obtain earphone fitting degree information of the earphone head, and the current equalizer parameter of the wired earphone is adjusted according to the earphone fitting degree information. The detecting operation of the fitting degree can be to determine the information of the fitting degree of the earphone through sound wave leakage information, wherein the sound wave leakage information refers to leakage information of audio output by the earphone head leaking from an ear cavity to the outside. For example, a section of test audio can be played in advance through the earphone head, the feedback microphone receives reflected sound waves of the test audio after multiple reflections in the ear cavity, the reflected sound waves are compared with original sound waves corresponding to the test audio, the sound wave leakage amount is determined, and then the earphone fit degree information is determined according to the sound wave leakage amount. After the earphone fitting degree information is obtained, current equalizer parameters of the earphone are adjusted according to the earphone fitting degree information, and sound wave leakage loss of the audio played by the earphone on the corresponding frequency band is caused due to the change of the earphone fitting degree, so that the tuning effect of the equalizer is improved, and a better sound quality test is brought to a user.

In one possible embodiment, the step of performing a preset adjustment operation on the equalizer parameters comprises:

step B10, obtaining sound wave leakage information of the earphone head;

and B20, adjusting the equalizer parameters according to the sound wave leakage information.

Specifically, the sound wave leakage information is leakage information in which audio output from the headphone head leaks to the outside from an ear cavity formed by the headphone and the human ear. For example, a section of test audio can be played in advance through the earphone head, the feedback microphone receives reflected sound waves of the test audio after multiple reflections in the ear cavity, the reflected sound waves are compared with original sound waves corresponding to the test audio, the sound wave leakage amount is determined, and then the earphone fit degree information is determined according to the sound wave leakage amount. After the earphone attaching degree information is obtained, the current equalizer parameters of the earphone are adjusted according to the earphone attaching degree information, and the sound wave leakage loss of the audio played by the earphone on the corresponding frequency band due to the change of the earphone attaching degree is compensated, so that the tuning effect of the equalizer is improved, and a better sound quality test is brought to a user.

To aid in understanding the present application, a specific embodiment is illustrated in which a test audio is played out of the speaker of the wired headset in a 0 to 1KHz variation with a gain of-30 dB. Original sound waves corresponding to the test audio are collected by the feedback microphone after being reflected for multiple times in the auditory canal, then reflected audio signals collected by the feedback microphone and the original audio signals corresponding to the test audio are compared and analyzed through a main control chip of the wired earphone, sound wave leakage information of the test audio in different frequency bands is obtained, and then current equalizer parameters of the wired earphone are adjusted according to the sound wave leakage information. It should be noted that the specific embodiments are only for understanding the present application and do not limit the present application, and more modifications may be made based on the specific embodiments and the protection scope of the present application.

In one possible embodiment, the step of obtaining acoustic leakage information of the headset head includes:

step C10, acquiring first audio information of the earphone head and acquiring second audio information of the first audio information after the first audio information is propagated, wherein the first audio information is formed by superposing sound wave signals of a preset frequency band;

step C20, generating sound wave leakage information of the earphone head according to the first audio information and the second audio information;
