The singular forms "a", "an" and "the" may include the plural forms as well.
At present, the traditional single sound field calibration method cannot adjust the center position of a sound field, so that the experience effect of a user is poor, and the user requirements cannot be met. Therefore, the application provides a method, a system and equipment for automatically controlling a main driving sound stage, so that the purpose of providing the center position of the sound stage for users with different heights, weights and driving habits is achieved, and the optimal music experience is provided for different users.
Referring to fig. 1, fig. 1 is a flow chart illustrating main steps of a main driving sound stage automatic control method according to an embodiment of the present invention. As shown in fig. 1, the main driving sound stage automatic control method in the embodiment of the present invention mainly includes the following steps S101 to S103.
Step S101: seat position information and relative position information of the driver's head with respect to the seat are acquired. Specifically, when a driver gets on the vehicle, the driver habitually adjusts the main driving seat to meet the driving habit of the driver, and mainly adjusts the front, the back, the height, the backrest elevation angle and the like of the seat to realize seat adjustment, so that the seat position information may include at least one of seat horizontal position information, seat height position information and seat backrest elevation angle information. The relative position information of the driver's head with respect to the seat may be the relative position of the driver's head with respect to the seat headrest.
Step S102: the first driver head relative coordinates are determined based on the seat position information and the relative position information of the driver's head with respect to the seat. In this step, first, absolute coordinates of the current seat headrest may be obtained based on the seat position information and the seat size calculation; the first driver head relative coordinate is then determined using a fuzzy algorithm based on the absolute coordinates of the current seat headrest and the relative position of the driver's head with respect to the seat headrest. The relative coordinates of the head of the driver are determined through the absolute coordinates of the current seat headrest and the relative position of the head of the driver relative to the seat headrest, the method is novel, and a basis is provided for determining the current sound field center position in the later period.
Step S103: and obtaining the current sound stage center position based on the relative head coordinates of the first driver. After the current sound field center position is obtained, the main driving sound field can be controlled based on the current sound field center position, for example: the vehicle-mounted navigation multimedia terminal can adjust the delay proportion information of each audio channel according to the current sound field center position, and sends the delay proportion information to the audio DSP unit through a USART or I2C protocol, the audio DSP unit adjusts the delay proportion of each audio channel according to the delay proportion information, sends corresponding delay analog audio signals to each audio channel after DAC conversion, and the power amplifier receives the corresponding delay analog audio signals sent to each audio channel by the audio DSP unit and outputs the delay analog audio signals to the loudspeaker for sounding after amplifying the delay analog audio signals through the power amplifier. In practical application, the main driving sound stage can also be controlled based on the sound stage center position by using the common technical means in the prior art, and details are not repeated here.
The specific process of obtaining the current sound stage center position in this step can be implemented by steps S1031 to S1031, which are not described herein.
Based on the above steps S101 to S103, on the basis of obtaining the seat position information and the relative position information of the head of the driver with respect to the seat, the relative coordinates of the head of the first driver are further determined, so as to determine the current sound stage center position, thereby achieving the purpose of providing the sound stage center position for users with different heights, weights and driving habits, and providing the best music experience for different users.
Step S1031: judging whether the relative head coordinates of the first driver determined in the step S102 are consistent with the relative head coordinates of the second driver, wherein the relative head coordinates of the second driver are the relative head coordinates of the driver stored last time; if the two are consistent in comparison, adding an identification bit 0 to the relative coordinates of the head of the first driver; and if the comparison between the first driver head and the second driver head is inconsistent, adding an identification position 1 to the relative coordinates of the first driver head.
Step S1032: and judging whether the head part relative coordinate identification position of the first driver is 1 or not, as shown in fig. 2. And when the relative coordinate identification position of the head of the first driver is 0, taking the sound field position corresponding to the relative coordinate of the head of the driver stored last time as the current sound field center position, namely directly playing the music by using the sound field position stored last time. Specifically, the sound stage position corresponding to the relative head coordinates of the driver stored last time may be a main driving surround sound stage position set by a disc-jockey at the time of vehicle shipment, or may be a sound stage position corresponding to the driver who has driven the vehicle last time. And when the head of the first driver is 1 relative to the coordinate identification position, determining the current sound stage center position by using a sound stage self-calibration method.
Specifically, when sound stage self-calibration is performed, first, the third driver head relative coordinate in which the difference between the first driver head relative coordinate and the driver head relative coordinate in the driver head relative coordinate history data set is smaller than the difference threshold is acquired. And when the historical data set of the relative head coordinates of the driver comprises a third relative head coordinate of the driver, wherein the difference value between the third relative head coordinate of the driver and the first relative head coordinate of the driver is smaller than the difference threshold value, determining the current sound field center position based on the third relative head coordinate of the driver, namely taking the sound field position corresponding to the third relative head coordinate of the driver as the current sound field center position. When the historical data set of relative head coordinates of the driver contains a plurality of relative head coordinates of a third driver, the difference value between the relative head coordinates of the first driver is smaller than the difference value threshold value, taking the sound field position corresponding to the average value of the relative head coordinates of the third driver as the current sound field center position; the sound stage center position may be determined as the current sound stage center position, which corresponds to the relative head coordinates of the third driver whose difference between the relative head coordinates of the first driver is the smallest. And after the current sound field center position is obtained, replacing the sound field data stored last time with the current sound field center position to further realize music playing. Generally, the weight of the driver may affect the fore-and-aft position, the height position, the backrest elevation angle, and the like of the seat. Therefore, the weight of the driver also affects the sound stage center position. The historical data set of the relative head coordinates of the driver is a database, and the database stores the relative head coordinates of the driver with different heights, weights and driving habits and the sound field center position corresponding to the relative head coordinates of the driver.
By adding the identification position to the relative coordinate of the head of the driver and further acquiring the sound stage center position in a self-calibration mode, the purpose of providing different sound stage center positions for users with different heights, weights and driving habits is achieved, automatic control over the sound stage center position is achieved, and user experience is improved.
It should be noted that, although the foregoing embodiments describe each step in a specific sequence, those skilled in the art will understand that, in order to achieve the effect of the present invention, different steps do not necessarily need to be executed in such a sequence, and they may be executed simultaneously (in parallel) or in other sequences, and these changes are all within the protection scope of the present invention.
