[0030] Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein.

[0031] At present, the development of new energy vehicle technology in the vehicle cockpit field and the in-depth application of intelligent technology are endless, and the car audio system has the characteristics of large quantity, high power, strong algorithm and good sound effect.

[0032] In the current mainstream audio surround sound systems, speakers are generally placed on the headrests of the seats. Due to the limited area of ​​the headrests, the size of the audio cabinet is restricted, and it is close to the human ear. If multimedia music is played, the small cabinet volume and poor sound quality will affect the driving experience. This limits the headrest speakers to only emit navigation, voice calls and other sounds in specific modes, and cannot be fully coordinated with the main sound units of other speaker systems in the vehicle for effective utilization.

[0033] Moreover, in some scenarios, such as surround sound control and sound field control for independent seat privacy, real-time tracking control of light and dark areas, and vehicle turn signal scenarios, it is impossible to enable users to immerse themselves in the sound quality of the audio system.

[0034] Based on the above technical problems, the technical concept of the present invention is as follows: if the audio unit can be arranged in the shoulder area of ​​the seat, the sounding surface of the audio unit is ≥150mm away from the human ear in a straight line, and the shoulder audio can be actively adjusted for surround feeling on the central control screen, it can not only take into account the vehicle prompt sound, alarm sound, navigation sound, telephone, multimedia, and voice functions, but also provide passengers with immersive surround multimedia sound effects. Specifically, during the use of the vehicle, if the operation information associated with the audio playback event can be obtained, the control information of the audio unit set in the shoulder area of ​​the seat can be determined, and the operation of the audio unit can be controlled to enable the user to enter an immersive experience of the sound quality of the audio system.

[0035] Figure 1 The schematic diagram of the configuration of the audio unit provided by the present invention is shown in FIG. Figure 1 As shown, it includes: a seat body and an audio unit arranged on the seat body.

[0036] The audio unit may include at least one audio device. Figure 1The following description will take two as an example and will refer to them as shoulder speaker L (the left side speaker component described below) and shoulder speaker R (the right side speaker component described below).

[0037] It should be understood that the shape of the seat body in the present invention is only an example and can be adjusted and set arbitrarily in actual scenarios.

[0038] Figure 2 The control schematic diagram of the audio unit provided by the present invention is shown as follows: Figure 2 As shown, it includes: a cockpit controller, a central control screen, an external power amplifier (system on chip (SOC), amplifier (AMP)), a main sound unit of the sound channel, and a shoulder audio unit.

[0039] Among them, the central control screen and cockpit controller assembly are composed of at least a power chip, a microcontroller unit (MCU), a controller area network (CAN) chip, an audio bus (A2B) chip, and a display screen; the external power amplifier assembly is composed of at least a SOC audio processing chip, CAN, A2B, a digital-to-analog converter (DAC), a power amplifier and other chips.

[0040] In addition, the cockpit controller assembly is connected to the vehicle battery through the vehicle's positive and negative power poles, and the vehicle supplies regular power to the system; the vehicle controller communicates with the AMP chip through CAN_H and CAN_L to implement functions such as fault information, wireless remote updates (Over-the-Air, OTA), and diagnosis.

[0041] and then, Figure 3 The schematic diagram of the position of the vehicle audio system provided by the present invention is shown in FIG. Figure 3 As shown, it includes: a left front channel, a right front channel, a center channel, a left rear channel, a right rear channel, a subwoofer channel, a sky channel, a left rear surround channel, a right rear surround channel, and a shoulder auxiliary sound unit (that is, the sound unit provided in the present invention).

[0042] Among them, for some sound channels, at least one of the following speakers is included: a tweeter, a mid-range speaker, a woofer, a surround speaker, a subwoofer, and a shoulder pillow speaker.

[0043] Based on the hardware schematics of the above embodiments, the technical solution of the present invention is described in detail through the following specific embodiments. The execution subject of the present invention is a vehicle, specifically a controller in the vehicle.

[0044] It should be noted that the following specific embodiments may be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0045] Figure 4 FIG. 1 is a flow chart showing a first embodiment of the audio control method of the present invention, which is executed by a vehicle. Figure 4 As shown, the method comprises the following steps:

[0046] Step 41, obtaining target operation information in the vehicle;

[0047] The target operation information is at least one preset operation information, and the operation information is an operation associated with the audio playback event;

[0048] In this step, target operation information related to the audio playback event is obtained, which is not limited to directly controlling audio-related operations or indirectly controlling audio-related operations.

[0049] In a possible implementation, the operation information may be a lever operation for turning a vehicle, an operation for starting music playback, a reversing operation, a volume adjustment operation, an ambience activation operation, and the like.

[0050] Step 42: Determine the target control information of the audio unit corresponding to the target operation information in the mapping relationship;

[0051] The mapping relationship records the correspondence between different operation information and different control information, and the control information is used to indicate a transmission instruction for transmitting audio to an audio unit, and the audio unit is arranged in a shoulder area of ​​a seat of the vehicle;

[0052] In this step, an audio unit is arranged in the shoulder area of ​​the vehicle seat. For example, the straight-line distance from the position to the human ear can be ≥150 mm. Based on different actual needs, the audio unit can be arranged on each seat in the vehicle, or only on the main driving position.

[0053] In actual implementation, the surround sense of the audio unit can be actively adjusted on the central control screen, which can take into account the vehicle's prompt sound, alarm sound, navigation sound, telephone, multimedia, and voice functions, and provide passengers with immersive surround multimedia sound effects. That is, examples of mapping relationships are not limited to the following.

[0054] Optionally, the mapping relationship includes at least one of the following:

[0055] 1. If the operation information indicates that the vehicle starts a left turn operation or a right turn operation, determine that the control information is to transmit the audio to the left audio component in the audio unit or to transmit the audio to the right audio component in the audio unit;

[0056] In this implementation, it can be sensed from the vehicle's steering angle sensor and other units that the user or the vehicle's intelligent driving system is controlling the vehicle to perform a steering operation, that is, the operation information instructs the vehicle to start a left turn operation or a right turn operation. At this time, the mapping relationship records the transmission of audio to the left audio component in the audio unit or the transmission of audio to the right audio component in the audio unit.

[0057] The audio unit may be a left audio component and a right audio component that are symmetrically arranged in the shoulder area.

[0058] 2. If the operation information indicates that the vehicle starts the independent control operation of the seat, determine that the control information is the volume of the audio transmitted to the audio unit in the seat or the switch of transmitting the audio to the audio unit in the seat;

[0059] In this implementation, touch keys for independent control of designated seats in the vehicle, or implementation of voice function wake-up, are provided on the vehicle's central control screen, other display units, devices that communicate with the vehicle, and hardware buttons. After responding to user manipulation, based on the specific content of the independent control operation, it can be determined whether the switch transmits audio to the audio unit in the seat, and controls the volume of the audio transmitted to the audio unit in the seat, that is, adjusts the sound volume of the audio unit, or whether to turn on the audio unit.

[0060] In a possible implementation, the independent control operation includes: volume adjustment or switch adjustment; under this implementation, the purpose of surround sound control and sound field control for independent privacy of seats can be achieved.

[0061] The specific implementation of 2 can be:

[0062] 2.1. If the independent control operation is volume adjustment, the control information is determined to be the volume of the audio transmitted to the audio unit in the seat; 2.2. If the independent control operation is switch adjustment, the control information is determined to be the switch transmitting the audio to the audio unit in the seat.

[0063] Based on the specific content of independent control operations, such as increasing the volume by 3, turning off the audio unit, etc.

[0064] 3. If the operation information indicates a brightness change operation of a light unit in the vehicle, determining the control information is a sound effect of transmitting audio to the audio unit following the brightness change;

[0065] In this implementation, the relevant functions of combining the interior ambient light with the sound of the in-car music are turned on. At this time, the operation of the brightness change of the lighting unit in the vehicle can be obtained. For example, when the brightness increases, the sound effect of the audio unit increases with the brightness change; when the brightness decreases, the sound effect of the audio unit decreases with the brightness change.

[0066] This implementation can achieve real-time tracking and control of bright and dark areas and produce an anti-signal masking effect.

[0067] 4. If the operation information instructs the vehicle to start the vehicle audio playback operation, determine the control information to transmit the harmony, live sound source and reverberated audio signals in the audio to the audio unit.

[0068] In this implementation, in order to allow the driver and passengers to experience the full surround sound effect in the cabin, that is, if it is detected that the vehicle audio playback operation is turned on, it is determined that the audio needs to be transmitted to the audio unit.

[0069] In a possible implementation, the harmonics, live sound sources and reverberated audio signals in the audio may be transmitted to the audio unit, and other audio signals in the audio may be played by other audio systems in the vehicle.

[0070] Step 43: operate the audio unit according to the target audio information corresponding to the target operation information and the target control information.

[0071] In this step, corresponding audio information can be obtained for different target operation information, which is recorded as target audio information. Then, based on the transmission instruction of transmitting audio to the audio unit, the target audio information is transmitted to the audio unit.

[0072] Optionally, the method involved in the embodiment of the present invention may be implanted (eg, in the form of program code) into a main audio software algorithm of a SOC (MCU+DSP) chip.

[0073] The embodiment of the present invention obtains target operation information in the vehicle, the target operation information is at least one preset operation information, and the operation information is an operation associated with the audio playback event; the target control information of the audio unit corresponding to the target operation information is determined in the mapping relationship, and the mapping relationship records the correspondence between different operation information and different control information, and the control information is used to indicate the transmission instruction of transmitting audio to the audio unit, and the audio unit is set in the shoulder area of ​​the seat of the vehicle; the audio unit is operated according to the target audio information corresponding to the target operation information, and the target control information. By obtaining the operation information associated with the audio playback event, the technical solution can accurately identify and respond to the operation requirements of the user or the vehicle in the vehicle, and associate the operation information with the control information, so that the vehicle can find the corresponding audio unit control information according to the target operation information, and then accurately control the audio unit in the shoulder area to fit and improve the user experience.

[0074] Based on the above embodiment, the target operation information indicates that the vehicle starts a left turn operation or a right turn operation, and the target control information is to transmit audio to the left audio component in the audio unit or to transmit audio to the right audio component in the audio unit. Accordingly, Figure 5FIG. 2 is a flow chart showing a second embodiment of the audio control method of the present invention, which is executed by a vehicle. Figure 5 As shown, step 43 may include the following steps:

[0075] Step 51, determining that the target audio information corresponding to the target operation information is the turn prompt audio information;

[0076] In this step, this embodiment takes the target operation information indicating that the vehicle starts a left turn operation or a right turn operation as an example, and the turn prompt audio information corresponding to the turn operation, that is, the target audio information, can be obtained.

[0077] Step 52: performing signal separation processing on the turn prompt audio information to obtain a first audio signal;

[0078] Wherein, the first audio signal is a left channel audio or a right channel audio;

[0079] In this step, audio signal processing technology is used to perform signal separation processing on the turn prompt audio information, and the audio signal of the left channel or the right channel is extracted according to the needs.

[0080] Taking the left turn operation as an example, the left channel audio, i.e., the first audio signal, is extracted from the turn prompt audio information; or, taking the right turn operation as an example, the right channel audio, i.e., the first audio signal, is extracted from the turn prompt audio information.

[0081] Step 53: Transmit the first audio signal to the left audio component in the audio unit or the right audio component in the audio unit.

[0082] In this step, the extracted left channel audio is transmitted to the left audio component in the audio unit; or the extracted right channel audio is transmitted to the right audio component in the audio unit.

[0083] In this implementation, if the seat is the driver's seat, this implementation can enable the driver to clearly feel the upcoming or ongoing steering operation of the vehicle, so as to avoid the risks that exist when the vehicle is turning.

[0084] The embodiment of the present invention determines that the target audio information corresponding to the target operation information is the turn prompt audio information, performs signal separation processing on the turn prompt audio information, obtains a first audio signal, and the first audio signal is a left channel audio or a right channel audio, and transmits the first audio signal to the left audio component in the audio unit or the right audio component in the audio unit. This technical solution can accurately identify and obtain the turn prompt audio information when the vehicle starts the left turn or right turn operation, decomposes the audio signal into the left channel audio or the right channel audio through signal separation processing, and distributes the left channel audio or the right channel audio to the left audio component or the right audio component in the audio unit, so that the turn prompt audio can form a clear directionality in the user's ears.

[0085] Based on the above embodiment, the target operation information instructs the vehicle to start the vehicle audio playback operation, and the target control information is to transmit the audio to the audio unit. Accordingly, Figure 6 FIG. 4 is a flow chart showing a third embodiment of the audio control method of the present invention, which is executed by a vehicle. Figure 6 As shown, step 41 may include the following steps:

[0086] Step 61: Determine that the target audio information corresponding to the target operation information is the audio information to be played;

[0087] In this step, the target operation information instructs the vehicle to start the vehicle audio playback operation, that is, the audio unit is required to play the audio. At this time, the audio information to be played is first obtained and recorded as the target audio information.

[0088] Optionally, the audio information to be played may be music, video, etc.

[0089] Step 62: performing signal separation processing on the audio information to be played to obtain a second audio signal;

[0090] The second audio signal is the harmony, live sound source and reverberated audio signal in the audio information to be played;

[0091] In this step, after the audio information to be played is obtained, the audio information to be played is subjected to signal separation processing, including human voice, musical instrument, background, harmony, scene, etc.

[0092] Optionally, the harmony, the live sound source and the reverberated signal in the audio information to be played are reverberated and added to obtain a second audio signal.

[0093] In one possible implementation, Figure 7 The present invention provides a schematic diagram of the processing flow of the audio information to be played, combined with Figure 7 ,right Figure 6 The embodiments are illustrative.

[0094] exist Figure 7 In the process, after separating the audio information to be played, you can also get audio such as human voice, musical instrument, background, etc. At this time, the human voice is output by the door speaker, the musical instrument is output by the 2D surround speaker, and the background sound is output by the 3D surround speaker.

[0095] Step 63: Transmit the second audio signal to the audio unit.

[0096] In this step, the separated second audio signal is transmitted to the audio unit so that the audio unit plays it.

[0097] Optionally, before executing step 63, the second audio signal may be delayed according to distance information between the audio unit and other audio units in the vehicle audio system to obtain a delayed second audio signal.

[0098] In this implementation, since the audio unit in the shoulder area is closer to the human ear, and other audio units, namely the 3D surround speakers, are farther away from the human ear, it is necessary to delay the sound of the audio unit to ensure that the sound propagation timing is consistent and reaches the human ear.

[0099] At this time, based on the distance information between the audio unit and other audio units in the vehicle audio system, the second audio signal may be delayed, that is, the specific situation of the delay is determined based on the distance information.

[0100] Optionally, before executing step 63, the second audio signal may be subjected to high-pass, low-pass, or band-pass filtering to obtain a filtered second audio signal.

[0101] In this implementation, each speaker signal in the vehicle's main sound unit (including the second audio signal transmitted to the audio unit) is controlled individually, and each speaker channel needs to be high-pass, low-pass, and band-pass filtered so that different speakers play signals in different frequency bands.

[0102] The embodiment of the present invention determines that the target audio information corresponding to the target operation information is the audio information to be played, performs signal separation processing on the audio information to be played, obtains a second audio signal, and the second audio signal is the harmony, live sound source and reverberated audio signal in the audio information to be played, and transmits the second audio signal to the audio unit. This technical solution can significantly improve the sound effect and immersion in the car by separating and processing the audio information to be played and transmitting it directionally to the audio unit on the shoulder of the seat.
