And in the acquired left and right earphones of the earphone, calculating the distance between the two position coordinates by using the first space position coordinate and the second space position coordinate sent by the respective position sensors, thereby obtaining the relative position distance between the left earphone and the right earphone of the earphone.
Specifically, for example, in the application scenario shown in fig. 6, a first spatial position and a second spatial position sent by position sensors in left and right earpieces of the headset are obtained, position coordinates in a spatial coordinate system created with the terminal position as an origin are obtained, and a relative position distance between the first spatial position and the second spatial position corresponding to the left and right earpieces of the headset in a current spatial coordinate system is calculated according to the respective position coordinates.

and f, acquiring a first coordinate of the first space position in the space coordinate system and a second coordinate of the second space position in the space coordinate system.
In a space coordinate system established by taking the terminal position as an origin, a first coordinate of a left earphone position sensor of the earphone corresponding to a first space position and a second coordinate of a right earphone position sensor of the earphone corresponding to a second space position are obtained.
Specifically, for example, in the current spatial environment, with the three-dimensional coordinate position of the terminal as the origin point P (0, 0), in the established spatial coordinate system, the coordinates P (4, -4, 5) of the first spatial position transmitted by the position sensor installed in the left earpiece of the headset are acquired, the coordinates P (4, -4, 5) of the first spatial position are marked as the first coordinates, the coordinates P (-2, -5, 14) of the second spatial position transmitted by the position sensor installed in the right earpiece of the headset are acquired, and the coordinates P (-2, -5, 14) of the second spatial position are marked as the second coordinates.

Specifically, for example, in the application scenario shown in fig. 6, by using the pythagorean theorem algorithm of the spatial coordinate distance, the relative position distance between the first coordinate P (4, -4, 5) of the left earpiece position sensor corresponding to the first spatial position and the second coordinate P (-2, -5, 14) of the right earpiece position sensor corresponding to the second spatial position is calculated to be 10.86 unit distances, and then the 10.86 unit distances are the length of the bottom side of a virtual triangle constructed by using the origin P (0, 0) as the vertex and using the two bottom points of the first coordinate P (4, -4, 5) and the second coordinate P (-2, -5, 14), and the length is marked as the first length, which is 10.86 unit lengths.

And switching and adjusting the output sound channel or sound source output mode of the earphone according to the comparison result between the detected relative position distance between the first space position and the second space position and the length of the connecting line between the left bottom point and the right bottom point of the preset triangle, namely the length of the bottom side of the preset triangle, and the matching result between the virtual triangle which is created by respectively taking the terminal position, the first space position and the second space position as the top point and each bottom point and the left and right earphone marks of the earphone corresponding to each bottom point of the preset triangle.
It should be noted that, a triangle is preset as a triangle model created by using the terminal as a vertex, the left earpiece of the earphone as a left bottom point, and the right earpiece of the earphone as a right bottom point, and the bottom edge length of the triangle model is a standard distance length between the left ear and the right ear of the human head.
Specifically, for example, according to the application scenario shown in fig. 6, when the comparison result between the relative position distance between the first spatial position and the second spatial position and the first length, that is, the length of the bottom side of the virtual triangle, and the connection line between the left bottom point and the right bottom point of the preset triangle and the second length, that is, the length of the bottom side is detected, the audio source output mode of the audio application output by the terminal is switched, or the comparison result between the first length of the bottom side of the virtual triangle, that is, the first length of the bottom side of the virtual triangle, and the second length of the bottom side of the preset triangle is combined with the matching result of the headphone marks corresponding to the virtual triangle, the preset triangle, and each of the left and right bottom points, so as to switch and adjust the left and right output channels of the headphones.

and h, when detecting that the difference value between the first length and the second length of the bottom edge of the preset triangle is larger than a preset threshold value, switching the stereo output mode to a mono output mode.
And when the difference value between the first length of the bottom edge of the virtual triangle corresponding to the first spatial position and the second length of the bottom edge of the preset triangle is larger than the preset threshold value, switching the stereo output mode applied by the current audio output of the terminal to a mono output mode.
It should be noted that the preset threshold is a maximum allowable difference value set according to the distance difference between the left ear and the right ear of different human heads.
Specifically, for example, in the application scenario shown in fig. 6, if a difference between a relative position distance between a first spatial position sent by a position sensor in a left earphone of the headset and a second spatial position sent by a position sensor in a right earphone of the headset, that is, a first length of a bottom side of a virtual triangle is 10.86 unit lengths, and a second length of a bottom side of a preset triangle, that is, a standard distance length between a left ear and a right ear of a human head is 5.86 unit lengths (one unit is approximately equal to 2.33 centimeters), is 5 unit lengths, and is greater than a preset threshold value of 1.2 unit lengths, it is determined that the user currently wears only one earphone, and at this time, the terminal device connected to the current earphone outputs audio application, and a stereo output mode for outputting audio data is switched to a mono output mode.

And when the difference value between the first length of the virtual triangle bottom side corresponding to the first space position and the second length of the preset triangle bottom side is smaller than the preset threshold value, but the left and right earphone marks of the earphone corresponding to the left and right bottom points of the virtual triangle and the preset triangle are not matched, switching the preset output sound channels of the current stereo output of the earphone between each other.
It should be noted that, when the terminal outputs audio in a stereo output mode, the preset output channel is a left channel in which a left earpiece of the headset device outputs stereo, and a right channel in which a right earpiece of the headset device outputs stereo.
Specifically, for example, when the relative positional distance between a first spatial position transmitted by a position sensor in the left earpiece of the headset and a second spatial position transmitted by a position sensor in the right earpiece of the headset, namely a first length of the base of the virtual triangle and a second length of the base of the preset triangle, namely the difference value between the standard lengths which are equal to the left ear and the right ear of the head of the human body is less than a preset threshold value of 1.2 unit lengths, but when the left bottom point of the virtual triangle corresponds to the earphone mark of the earphone device and is not matched with the earphone mark of the earphone device corresponding to the left bottom point of the preset triangle, the user is determined to wear two earphones currently, however, the positions of the left and right earphones corresponding to the left and right ears of the earphone currently worn by the user are just opposite, at this time, the left channel of the stereo output of the left earphone of the preset earphone device is switched to the right channel, and the right channel of the stereo output of the right earphone of the earphone device is switched to the left channel.
And j, when detecting that the difference value between the first length and the second length of the bottom edge of the preset triangle is smaller than or equal to the preset threshold value and the virtual triangle is matched with a receiver corresponding to the bottom point of the preset triangle, keeping the preset output sound channel.
And when the difference value between the first length of the bottom edge of the virtual triangle corresponding to the first space position and the second length of the bottom edge of the preset triangle is smaller than the preset threshold value, and the virtual triangle is matched with the left and right earphone marks of the earphone corresponding to the left and right bottom points of the preset triangle, keeping the preset output sound channel of the current output stereo of the earphone.
Specifically, for example, when the relative positional distance between a first spatial position transmitted by a position sensor in the left earpiece of the headset and a second spatial position transmitted by a position sensor in the right earpiece of the headset, namely a first length of the base of the virtual triangle and a second length of the base of the preset triangle, namely the difference value between the standard lengths which are equal to the left ear and the right ear of the head of the human body is less than a preset threshold value of 1.2 unit lengths, and the bottom point of the virtual triangle corresponds to the earphone mark of the earphone device, when the bottom point of the virtual triangle is matched with the earphone mark of the earphone device corresponding to the bottom point of the preset triangle, the user is determined to wear two earphones currently, and the left and right earphones of the earphone worn by the user currently correspond to the left and right ear positions correctly, at the moment, the left earphone of the preset earphone equipment is kept to output a stereo left sound channel, and the right earphone of the earphone equipment outputs a stereo right sound channel.
In this embodiment, when the earphone is connected with the terminal, a sound source output mode of the current running application of the terminal is detected; when the sound source output mode is detected to be a stereo output mode, acquiring a first spatial position of a left earphone of the earphone and a second spatial position of a right earphone of the earphone; detecting a relative positional distance of the first spatial position and the second spatial position with respect to each other; and switching the output sound channel and the sound source output mode of the earphone according to the relative position parameter.

Realizes the automatic detection of the relative position of the left receiver and the right receiver of the earphone worn by the user, matches the relative position of the left receiver and the right receiver of the earphone worn by the user with the relative position of the left receiver and the right receiver of the preset earphone, and automatically determines whether the user normally wears the left and right earphones of the earphone or not by detecting the relative position distance between the left earphone and the right earphone corresponding to the bottom point of the constructed virtual triangle and the preset triangle, or whether the left and right receiver positions of the earphone are correct or not, and when the user wears one earphone receiver or the left and right receiver positions of the earphone are incorrect, the switching of the earphone output sound channel and the sound source output mode is automatically completed, the user can obtain a good audio listening effect when wearing the left earphone and the right earphone of the earphone reversely or only wearing one earphone, so that the user can wear the earphone at will and enjoy higher use experience.
