[0045] It should be noted that if the embodiments of this application involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0046] Furthermore, if the embodiments of this application involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. If the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed in this application.

[0047] Figure 1 The illustration schematically shows a flowchart of a method for compensating the output volume of a voice broadcasting device according to an embodiment of this application. Figure 1As shown in the figure, this application provides a method for compensating the output volume of a voice broadcasting device, applied to a vehicle, the vehicle including a voice broadcasting device and a seat, the method including the following steps.

[0048] Step 101: Detect whether there is a user in each seat in the vehicle, and determine the tag value of each seat based on the detection results.

[0049] The vehicle may include a voice broadcasting device and seats. The voice broadcasting device can be a speaker, horn, etc. The processor can detect whether a user is in each seat in the vehicle and determine the tag value of each seat based on the detection results. Specifically, pressure sensors installed at the bottom of the seats can detect the pressure of each seat to determine whether a user is in the seat.

[0050] In this embodiment of the application, determining the label value of each seat based on the detection results includes: for any seat, if the detection result of any seat indicates that a user is present on any seat, determining the label value of any seat to be a first preset value; for any seat, if the detection result of any seat indicates that no user is present on any seat, determining the label value of any seat to be a second preset value.

[0051] The processor can determine the tag value for each seat based on the detection results. Specifically, for any given seat, the processor can determine whether the detection result for that seat indicates the presence of a user. If the detection result for any given seat indicates the presence of a user, the processor can determine the tag value for that seat to be a first preset value. The first preset value can be determined based on user needs; in a specific embodiment, the first preset value can be 1. If the detection result for any given seat indicates the absence of a user, the processor can determine the tag value for that seat to be a second preset value. The second preset value can be determined based on user needs; in a specific embodiment, the second preset value can be 0.

[0052] In one embodiment, such as Figure 2 As shown, the vehicle may include four seats: a driver's seat, a front passenger seat, a rear left seat, and a rear right seat. Each seat includes four mid-range speakers, two tweeters, one center speaker, and one woofer. A pressure sensor is installed under each seat. Figure 3As shown, the pressure sensor can include a bridge sensor and an HX711 chip. The bridge sensor consists of a Wheatstone bridge composed of four resistors. When unloaded, the bridge is in a balanced state, meaning the output voltage E0 = the input voltage Ex. When a heavy object is placed on the tray, the force F > 0, causing the metal strip to deform to a certain extent. This changes the resistance of the strain gauges R1 to R4, resulting in a voltage difference between the output voltage E0 and the output voltage Ex. The HX711 chip has two analog input channels and integrates a 128x gain programmable amplifier, making it a high-precision measurement module. If a user is detected in the driver's seat and no other users are detected in the other seats, the driver's EQ (Equalizer) will be activated; if a user is detected in the driver's seat and / or front passenger seat and no other users are detected in the other seats, the front EQ will be activated; if a user is detected in the driver's seat and / or front passenger seat and a user is detected in the rear seats, the entire vehicle's EQ will be activated; if no user is detected in the driver's seat and / or front passenger seat and a user is detected in the rear seats, the rear EQ will be activated; if no user is detected in the entire vehicle, the entire vehicle's EQ will be activated, thus automatically adjusting the EQ according to the user's location.

[0053] Step 102: Obtain the initial distance between each seat and each voice broadcasting device in the vehicle.

[0054] Step 103: Determine the actual distance between each seat and each voice broadcasting device.

[0055] The processor can obtain the initial distance between each seat and each voice broadcasting device in the vehicle. Preferably, the initial distance can refer to the distance between the seat headrest and the voice broadcasting device, and the initial distance can be set by the user based on their needs during the vehicle's layout. The processor can determine the actual distance between each seat and each voice broadcasting device in the vehicle.

[0056] In this embodiment of the application, the vehicle further includes a Hall sensor. Determining the actual distance between each seat and each voice broadcasting device includes: acquiring a pulse wave between any seat and any voice broadcasting device collected by the Hall sensor; determining the forward and backward movement distance, vertical movement distance, and tilt angle of any seat relative to any voice broadcasting device based on the pulse wave; and determining the actual distance between any seat and any voice broadcasting device based on the forward and backward movement distance, vertical movement distance, and tilt angle.

[0057] The vehicle also includes Hall sensors. Specifically, for any seat and any voice broadcasting device, the processor can acquire the pulse wave between the seat and the voice broadcasting device collected by the Hall sensors. After obtaining the pulse wave between the seat and the voice broadcasting device, the processor can determine the forward / backward movement distance, vertical movement distance, and tilt angle of the seat relative to the voice broadcasting device based on the pulse wave. In a specific embodiment, each seat can be equipped with three Hall sensors, used to measure the forward / backward movement, seat movement, and tilt angle of the seat, respectively. The processor can determine the actual distance between each seat and each voice broadcasting device. The processor can pre-store a relationship table between pulse waves, movement distances, and tilt angles, which can be constructed based on multiple historical pulse waves, historical movement distances, and historical tilt angles. After obtaining the forward / backward movement distance, vertical movement distance, and tilt angle of the seat relative to the voice broadcasting device, the processor can determine the actual distance between the seat and the voice broadcasting device based on the forward / backward movement distance, vertical movement distance, and tilt angle. For example, as... Figure 4 As shown, the initial straight-line distance between seat m and speaker n is Xmn, the horizontal and vertical distance is Zmn, and the seat back height of seat m is G. The processor can determine the forward and backward movement distance Sa, the vertical movement distance Sb, and the seat rotation angle α of seat m relative to speaker n based on the pulse wave of the Hall sensor. Then, based on the forward and backward movement distance Sa, the vertical movement distance Sb, and the seat rotation angle α, the actual distance Ymn between seat m and speaker n is determined.

[0058] Step 104: Determine the deviation distance between each seat and each voice broadcasting device based on the initial distance and the actual distance between each seat and each voice broadcasting device.

[0059] Step 105: Determine the weighted deviation distance for each voice broadcasting device based on all deviation distances and the label values ​​for all seats.

[0060] After determining the actual distance between each seat and each voice broadcasting device, the processor can determine the deviation distance between each seat and each voice broadcasting device based on the initial distance and the actual distance between them. In an optional embodiment, the processor can determine the deviation distance between each seat and each voice broadcasting device as the difference between the actual distance and the initial distance. For example, as... Figure 5As shown, the deviation distance between seat m and voice broadcasting device n is expressed as Amn = |Ymn - Xmn|, where Amn represents the deviation distance between seat m and voice broadcasting device n, Ymn represents the actual distance between seat m and voice broadcasting device n, and Xmn represents the initial distance between seat m and voice broadcasting device n. After determining the deviation distance between each seat and each voice broadcasting device, the processor can determine the weighted deviation distance of each voice broadcasting device based on all deviation distances and the label values ​​of all seats.

[0061] In this embodiment of the application, determining the weighted deviation distance of each voice broadcasting device based on all deviation distances and the label values ​​of all seats includes: determining the weight of each seat relative to each voice broadcasting device based on the actual distance between each seat and each voice broadcasting device; and for each voice broadcasting device, determining the weighted deviation distance of the voice broadcasting device based on the weights of all seats relative to the voice broadcasting device, the deviation distance between the voice broadcasting device and all seats, and the label values ​​of all seats.

[0062] The processor can determine the weighted deviation distance of each voice broadcasting device based on all deviation distances and the label values ​​of all seats. Specifically, the processor can determine the weight of each seat relative to each voice broadcasting device based on the actual distance between each seat and each voice broadcasting device. In this embodiment, determining the weight of each seat relative to each voice broadcasting device based on the actual distance between each seat and each voice broadcasting device includes determining the weight of each seat relative to each voice broadcasting device according to formula (2):

[0063]

[0064] Among them, W mn Y represents the weight of the m-th seat relative to the n-th voice broadcasting device. mn Y is the actual distance between the m-th seat and the n-th voice broadcasting device. 1n Y is the actual distance between the first seat and the nth voice broadcasting device. 2n Y is the actual distance between the second seat and the nth voice broadcasting device. pn Let be the actual distance between the p-th seat and the n-th voice broadcasting device, N be the total number of voice broadcasting devices, and M be the total number of seats in the vehicle.

[0065] After determining the weight of each seat relative to each voice broadcasting device, for each voice broadcasting device, the processor can determine the weighted deviation distance of the voice broadcasting device based on the weights of all seats relative to the voice broadcasting device, the deviation distance between the voice broadcasting device and all seats, and the label values ​​of all seats. This more intuitively reflects the listening effect of users in different seats in the vehicle, which is beneficial for subsequent output compensation.

[0066] In this embodiment, determining the weighted deviation distance of the voice broadcasting device based on the weights of all seats relative to the voice broadcasting device, the deviation distance between the voice broadcasting device and all seats, and the label values ​​of all seats includes determining the weighted deviation distance of the voice broadcasting device according to formula (1):

[0067]

[0068] Among them, S n W is the weighted deviation distance of the nth voice broadcasting device. mn Let A be the weight of the nth voice broadcasting device relative to the mth seat. mn Let T be the deviation distance between the nth voice broadcasting device and the mth seat. m Let m be the label value of the m-th seat, where M is the total number of seats in the vehicle.

[0069] Step 106: Determine the compensation volume for each voice broadcasting device based on the weighted deviation distance and initial output volume of each voice broadcasting device, in order to compensate each voice broadcasting device.

[0070] After determining the weighted deviation distance of each voice broadcasting device, the processor can determine the compensation volume of each voice broadcasting device based on the weighted deviation distance and the initial output volume of each voice broadcasting device, so as to compensate each voice broadcasting device.

[0071] In this embodiment of the application, determining the compensation volume of each voice broadcasting device based on the weighted deviation distance and initial output volume of each voice broadcasting device includes:

[0072] The compensated output volume of each voice broadcasting device is determined according to formula (3):

[0073] V n =(CS n +1)×V n ′,(n=1、2…N) (3)

[0074] Among them, V n Let S be the output volume of the nth voice broadcasting device after compensation, where C is a constant and S is a variable. n V is the weighted deviation distance of the nth voice broadcasting device. n′ represents the initial output volume of the nth voice broadcasting device, and N represents the total number of voice broadcasting devices;

[0075] The difference between the compensated output volume of each voice broadcasting device and the initial output volume of each voice broadcasting device is determined as the compensated volume of each voice broadcasting device.

[0076] The processor determines the compensated output volume for each voice broadcasting device based on the weighted offset distance and initial output volume. After obtaining the compensated output volume for each voice broadcasting device, the processor determines the compensation volume for each device by the difference between the compensated output volume and the initial output volume. This allows for targeted adjustments to each voice broadcasting device based on the offset distance of all seats in the vehicle, effectively improving the user experience.

[0077] In one embodiment, taking speaker 1, seat 1, seat 2, seat 3, and seat 4 as an example, assuming the actual distance Y11 between seat 1 and speaker 1 is 0.5m, the actual distance Y21 between seat 2 and speaker 1 is 1m, the actual distance Y31 between seat 3 and speaker 1 is 1m, and the actual distance Y41 between seat 4 and speaker 1 is 2m, then the weight of seat 1 relative to speaker 1 is... Weight of seat 2 relative to speaker 1 Weight of seat 3 relative to speaker 1 Weight of seat 4 relative to speaker 1 Assume the deviation distance A11 between seat 1 and speaker 1 is 0.2m, the deviation distance A21 between seat 2 and speaker 1 is 0.1m, the deviation distance A31 between seat 3 and speaker 1 is -0.2m, and the deviation distance A41 between seat 4 and speaker 1 is 0.1m. Also, the label value T1 for seat 1 is 1, the label value T2 for seat 2 is 0, the label value T3 for seat 3 is 1, and the label value T4 for seat 4 is 1. Then, the weighted deviation distance of speaker 1... After obtaining the weighted offset distance S1 of speaker 1, the processor can determine the compensated output volume of speaker 1. Where C is a constant, meaning the output volume of speaker 1 needs to increase. Assuming the initial output volume V1' of speaker 1 is 10dB and the constant C is 15, then speaker 1 needs to compensate for a volume of 1dB, resulting in a compensated volume of 11dB. This allows the speaker volume to be adjusted in real-time based on the user's seat adjustments, meaning different speakers will output different compensated volumes depending on the seat's adjustment, thus meeting the personalized needs of different users. Ideally, the actual distance and offset distance of the seat can be the same as the actual distance and offset distance of the headrest for even better volume output.

[0078] The above technical solution enables personalized adjustment of the output volume of the voice broadcasting device corresponding to each seat, improves the output effect of the voice broadcasting device, achieves adaptive volume adjustment, and enhances the user experience.

[0079] Figure 1 This is a flowchart illustrating a method for compensating the output volume of a voice broadcasting device in one embodiment. It should be understood that, although... Figure 1 The steps in the flowchart are shown sequentially as indicated by the arrows, but these steps are not necessarily executed in the order indicated by the arrows. Unless otherwise specified herein, there is no strict order in which these steps are executed, and they can be performed in other orders. Figure 1 At least some of the steps in the process may include multiple sub-steps or multiple stages. These sub-steps or stages are not necessarily completed at the same time, but can be executed at different times. The execution order of these sub-steps or stages is not necessarily sequential, but can be executed in turn or alternately with other steps or at least some of the sub-steps or stages of other steps.

[0088] The in-vehicle entertainment module communicates with the in-vehicle power amplifier module and the in-vehicle gateway module via the in-vehicle bus. It is used to transmit digital audio signal streams to the in-vehicle power amplifier module via the in-vehicle bus. The in-vehicle bus is a communication protocol used in automotive and industrial applications.

[0089] The vehicle power amplifier module communicates with the vehicle gateway module via the vehicle bus, and communicates with the seat pressure sensor and the seat HALL sensor via a single bus. This is used to process the seat deviation distance, obtain the weighted deviation distance of each speaker, and obtain the output compensation amount based on the weighted deviation distance. Output compensation is then performed on each speaker based on the output compensation amount.

[0090] The vehicle gateway module is used to transmit host control button messages to the vehicle power amplifier module via the vehicle bus.

[0091] The seat pressure sensor is used to detect whether there is a person in the seat and transmits the seat information to the vehicle amplifier module via a single bus.

The internal memory A03 provides an environment for the operation of the operating system B01 and the computer program B02 stored in the non-volatile storage medium A04. The database stores data such as tag values, initial distance, actual distance, deviation distance, weighted deviation distance, initial output volume, and compensation volume. The network interface A02 communicates with external terminals via a network connection. When executed by the processor A01, the computer program B02 implements a method for compensating the output volume of a voice broadcasting device.
