[0037] The following describes exemplary embodiments of the present application in conjunction with the drawings. Various details of the embodiments of the present application are included to facilitate understanding, and they should be considered merely exemplary. Therefore, those of ordinary skill in the art should recognize that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the present application. Similarly, for the sake of clarity and conciseness, the description below omits the description of well-known functions and structures.

[0038] Embodiment 1

[0039] Figure 1 is a flowchart of a volume adjustment method provided in this embodiment, and this embodiment is applicable to adjusting the volume of in-vehicle audio. This method can be executed by a volume adjustment device, which can be composed of software and / or hardware and is generally integrated in an electronic device.

[0040] See Figure 1 , and this volume adjustment method includes the following steps:

[0041] S110. Determine the volume adjustment reference position according to the ear positions of the passengers.

[0042] Among them, the "ear positions of the passengers" refers to the positions where the ears of all passengers are located, and these ear positions can be obtained by collecting images through a camera.

[0043] Preferably, the step of determining the volume adjustment reference position according to the ear positions of the passengers includes:

[0044] Determine the reference position of each passenger according to the ear positions of the passengers;

[0045] Determine the volume adjustment reference position according to the reference positions of each passenger.

[0046] In the above preferred embodiment, first determine the reference position of each passenger, and then determine the volume adjustment reference position. The obtained volume adjustment reference position is more scientific and reliable.

[0047] Exemplarily, when it is detected that there is only 1 passenger (i.e., only the driver), the center position of the line connecting the two ears of the driver is used as the volume adjustment reference position. When it is monitored that there are multiple passengers, the center position of the line connecting the two ears of each passenger is used as the reference position of each passenger, and then the center position of the above reference positions is used as the volume adjustment reference position.

[0048] S120. Determine the values corresponding to the volume control points on the first axis and the second axis according to the volume adjustment reference position, the number of in-vehicle speakers, and the in-vehicle noise volume; wherein, the first axis is the line connecting the left side to the right side of the carriage, the second axis is the line connecting the front end to the rear end of the carriage, and the first axis and the second axis intersect at an intersection point.

[0049] Among them, the "in-vehicle noise volume" is obtained by comparing the original volume at the in-vehicle speaker with the current in-vehicle volume (which can be obtained through a microphone), and the in-vehicle noise volume = the current in-vehicle volume - the original volume at the in-vehicle speaker.

[0050] The "volume control point" is used as the basis for adjusting the volume of each in-vehicle speaker.

[0051] Preferably, the intersection point is the center point of the carriage.

[0052] The "center point of the carriage" refers to the geometric center of the carriage. For example, when the top view of the carriage is a regular rectangle or square, the center point of the carriage is the intersection point of the diagonals of the rectangle or square.

[0053] Preferably, the step of determining the values corresponding to the volume control points on the first axis and the second axis according to the volume adjustment reference position, the number of in-vehicle speakers, and the in-vehicle noise volume includes:

[0054] Based on the volume adjustment reference position, respectively determine the horizontal distance between the volume adjustment reference position and the right speaker in the vehicle and the vertical distance between the volume adjustment reference position and the front speaker in the vehicle; the horizontal distance refers to the distance along the first axis, and the vertical distance refers to the distance along the second axis;

[0055] Based on the horizontal distance, the distance between the left and right speakers in the vehicle, and the maximum gain number from the intersection point to the left and right sides of the carriage, determine the value corresponding to the volume control point on the first axis;

[0056] Based on the vertical distance, the distance between the front and rear speakers in the vehicle, the maximum gain number from the intersection point to the front and rear ends of the carriage, the number of speakers in the vehicle, and the vehicle interior noise volume, determine the value corresponding to the volume control point on the second axis.

[0057] Optionally, the calculation method for the value X corresponding to the volume control point on the first axis is: X = p × m × V / W, where 0.1 ≤ p ≤ 1, m is the horizontal distance, V is the maximum gain number from the intersection point to the left and right sides of the carriage, and W is the distance between the left and right speakers in the vehicle.

[0058] Preferably, the calculation method for the value X corresponding to the volume control point on the first axis is: X = K × lg(p × m × V / W), where 1 ≤ K ≤ 100, 0.1 ≤ p ≤ 1, m is the horizontal distance, V is the maximum gain number from the intersection point to the left and right sides of the carriage, and W is the distance between the left and right speakers in the vehicle. Among them, V is a preset value, generally 12. X is rounded according to the decimal places of V. If V is an integer, then X is rounded to an integer. The user can adjust the value of p according to the feeling. The value of K is, for example, 20.

[0059] Optionally, if the number of speakers in the vehicle is 4 or 8, the calculation method for the value Y corresponding to the volume control point on the second axis is: Y = p × n × H / L + a / K, where 1 ≤ K ≤ 100, 0.1 ≤ p ≤ 1, n is the vertical distance, L is the distance between the front and rear speakers in the vehicle, H is the maximum gain number from the intersection point to the front and rear ends of the carriage, and a is the vehicle interior noise volume.

[0060] Preferably, if the number of speakers in the vehicle is 4 or 8, the calculation method for the value Y corresponding to the volume control point on the second axis is: Y = K × lg(p × n × H / L + a), where 1 ≤ K ≤ 100, 0.1 ≤ p ≤ 1, n is the vertical distance, L is the distance between the front and rear speakers in the vehicle, H is the maximum gain number from the intersection point to the front and rear ends of the carriage, and a is the vehicle interior noise volume. Among them, H is a preset value, generally 24. Y is rounded according to the decimal places of H. If H is an integer, then Y is rounded to an integer.

[0061] Optionally, if the number of in-vehicle speakers is 6, the calculation method for the value Y corresponding to the volume control point on the second axis is: Y = p × n × H / L + a / K - z, where 1 ≤ K ≤ 100, 0.1 ≤ p ≤ 1, n is the vertical distance, L is the distance between the front and rear speakers in the vehicle, H is the maximum gain number from the intersection point to the front and rear ends of the carriage, a is the in-vehicle noise volume, and 0 ≤ z ≤ H / 6.

[0062] Preferably, if the number of in-vehicle speakers is 6, the calculation method for the value Y corresponding to the volume control point on the second axis is: Y = K × lg(p × n × H / L + a) - z, where 1 ≤ K ≤ 100, 0.1 ≤ p ≤ 1, n is the vertical distance, L is the distance between the front and rear speakers in the vehicle, H is the maximum gain number from the intersection point to the front and rear ends of the carriage, a is the in-vehicle noise volume, and 0 ≤ z ≤ H / 6. The user can adjust the value of z according to their own feelings.

[0063] The above various calculation formulas are derived based on the proportion of the left and right speakers in the vehicle according to the horizontal distance and the proportion of the front and rear speakers in the vehicle according to the vertical distance. When the above preferred formulas are used, the volume adjustment effect is better.

[0064] Preferably, when the passengers change, the change of the volume control point should be a step-by-step change. For example, if the value of the volume control point on the first axis was originally 0 and the changed value is 3, the change process is from 0 to 1 to 2 to 3, and it cannot directly jump from 0 to 3.

[0065] S130. Adjust the volume of the left and right speakers in the vehicle according to the value corresponding to the volume control point on the first axis; adjust the volume of the front and rear speakers in the vehicle according to the value corresponding to the volume control point on the second axis.

[0066] Specifically, the adjusting the volume of the left and right speakers in the vehicle according to the value corresponding to the volume control point on the first axis; adjusting the volume of the front and rear speakers in the vehicle according to the value corresponding to the volume control point on the second axis includes:

[0067] Determine the volume of the left speaker in the vehicle and the volume of the right speaker in the vehicle according to the value corresponding to the volume control point on the first axis, the original volume of the left speaker in the vehicle, and the original volume of the right speaker in the vehicle;

[0068] Determine the volume of the front speaker in the vehicle and the volume of the rear speaker in the vehicle according to the value corresponding to the volume control point on the second axis, the original volume of the front speaker in the vehicle, and the original volume of the rear speaker in the vehicle.

[0069] Among them, the "original volume of the left speaker inside the vehicle" refers to the volume of the left speaker inside the vehicle before adjusting the volume; similarly, the "original volume of the right speaker inside the vehicle" refers to the volume of the right speaker inside the vehicle before adjusting the volume, the "volume of the front speaker inside the vehicle" refers to the volume of the front speaker inside the vehicle before adjusting the volume, and the "volume of the rear speaker inside the vehicle" refers to the volume of the rear speaker inside the vehicle before adjusting the volume.

[0070] Preferably, if the value of the volume control point corresponding to the first axis is calculated using any of the foregoing formulas, and if the value of the volume control point corresponding to the first axis is a positive number, then adjust the volume of the right speaker inside the vehicle to increase the intensity of the positive number, and adjust the volume of the left speaker inside the vehicle to decrease the intensity of the positive number;

[0071] If the value of the volume control point corresponding to the first axis is calculated using any of the foregoing formulas, and if the value of the volume control point corresponding to the first axis is a negative number, then adjust the volume of the right speaker inside the vehicle to decrease the intensity of the absolute value of the negative number, and adjust the volume of the left speaker inside the vehicle to increase the intensity of the absolute value of the negative number;

[0072] If the value of the volume control point corresponding to the second axis is calculated using any of the foregoing formulas, and the value of the volume control point corresponding to the second axis is a positive number, then adjust the volume of the front speaker inside the vehicle to increase the intensity of the positive number, and adjust the volume of the rear speaker inside the vehicle to decrease the intensity of the positive number;

[0073] If the value of the volume control point corresponding to the first axis is calculated using any of the foregoing formulas, and the value of the volume control point corresponding to the first axis is a negative number, then adjust the volume of the front speaker inside the vehicle to decrease the intensity of the absolute value of the negative number, and adjust the volume of the rear speaker inside the vehicle to increase the intensity of the absolute value of the negative number.

[0074] Exemplarily, if the value of the volume control point corresponding to the first axis is 2, then adjust the volume intensity of the right speaker inside the vehicle to increase by 2 db, and adjust the volume intensity of the left speaker inside the vehicle to decrease by 2 db. If the value of the volume control point corresponding to the second axis is 2, then adjust the volume intensity of the front speaker inside the vehicle to increase by 2 db, and adjust the volume intensity of the rear speaker inside the vehicle to decrease by 2 db. If the value of the volume control point corresponding to the first axis is -2, then adjust the volume intensity of the right speaker inside the vehicle to decrease by 2 db, and adjust the volume intensity of the left speaker inside the vehicle to increase by 2 db. If the value of the volume control point corresponding to the second axis is -2, then adjust the volume intensity of the front speaker inside the vehicle to decrease by 2 db, and adjust the volume intensity of the rear speaker inside the vehicle to increase by 2 db.

[0075] The above-mentioned volume adjustment method first determines the volume adjustment reference position according to the ear positions of the passengers in the vehicle; then, based on this reference position, further combines the number of speakers in the vehicle and the volume of the in-vehicle noise to determine the values corresponding to the volume control points on the first axis and the second axis; finally, adjusts the volumes of the speakers on the left and right sides and the front and rear ends of the vehicle according to the above-mentioned values. This method comprehensively considers the ear positions, the number of speakers, and the volume of the in-vehicle noise, and automatically adjusts the volume of each speaker accordingly, without manual adjustment by the user, which is very convenient. Moreover, since it considers the ear positions of all passengers, it will not only meet the volume requirements of some passengers, and the passengers' satisfaction with the adjusted volume is higher.
