If there is a description of "first" or "second", it is only used to distinguish the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0027] In the description of the present invention, it should be noted that the terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention in combination with the specific content of the technical solution.

[0028] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described below are only some embodiments of the present invention, not all embodiments.

[0029] In the related art, a vehicle has an audio system, which is a vehicle entertainment device that can play audio to reduce the boredom of the driver and passengers during travel. At present, the audio system includes multiple speakers, which are distributed in different positions in the vehicle, such as the vehicle dashboard, door, trunk, etc. The speakers are generally built into the interior panels at the above positions to fix the speakers. Since the vehicle audio system reasonably arranges the positions of multiple speakers and limits the frequencies of the audio played by the multiple speakers, the audio system creates a better audio playback effect in the vehicle.

[0030] In order to meet the needs of drivers and passengers to listen to audio outside the car, in the related technology, the drivers and passengers carry Bluetooth speakers and can place the Bluetooth speakers at any location.

[0031] However, since the Bluetooth speaker is independent of the vehicle's audio system, it is difficult for the Bluetooth speaker and the vehicle's audio system to work together, and the audio playback of the Bluetooth speaker in the car will affect the audio playback effect of the vehicle's audio system.

[0032] Based on this, an embodiment of the present invention provides a method for controlling a vehicle audio system. When the speaker assembly 100 of the vehicle audio system is electrically connected to the vehicle audio system, the frequency range of the audio played by the vehicle audio system is limited to prevent the audio played by the vehicle audio system from affecting the overall sound effect of the audio system. When the speaker assembly 100 of the vehicle audio system is not electrically connected to the vehicle audio system, the vehicle audio system is wirelessly connected to the mobile terminal via the wireless communication module 200. After the vehicle audio system is separated from the vehicle audio system, it can play more audio of other frequencies, allowing the driver and passengers to obtain better audio effects outside the vehicle.

[0033] refer to Figures 1 to 5A vehicle audio control method according to an embodiment of the present invention is described. The control method is applied to a vehicle audio system, and the vehicle audio system is detachably connected to the vehicle.

[0034] The vehicle is provided with an audio system, and the vehicle audio is provided with a speaker assembly 100 and a wireless communication module 200. The speaker assembly 100 is detachably electrically connected to the sound box system, and the wireless communication module 200 can establish a wireless connection with a mobile terminal. The steering wheel control method is described below using a specific example.

[0035] Reference Figure 1 As shown, the vehicle audio control method of the embodiment of the present invention includes the following steps.

[0036] Step S100 , determining whether the speaker assembly 100 is electrically connected to the sound system.

[0037] Whether the vehicle audio system is electrically connected to the vehicle audio system will change the working mode of the vehicle audio system, so it is necessary to determine whether the speaker assembly 100 of the vehicle audio system is connected to the audio system. The audio system can send an electrical signal to the vehicle audio system, and whether the vehicle audio system receives the electrical signal as a sign to determine whether the vehicle audio system is connected to the audio system. When the vehicle audio system receives the electrical signal, it proves that the vehicle audio system is connected to the audio system.

[0038] Step S200 , when it is determined that the speaker assembly 100 is electrically connected to the sound system, the speaker assembly 100 is controlled to receive a first audio signal transmitted by the sound system, where the first audio signal has a first frequency range.

[0039] When it is determined that the speaker assembly 100 of the vehicle audio is connected to the audio system, proving that the driver and passengers wish to listen to audio in the car, the audio system can transmit a first audio signal to the speaker assembly 100 of the vehicle audio, wherein the frequency range of the first audio signal is limited to the first frequency range, and the speaker assembly 100 receives and plays the first audio signal, so as to limit the first audio signal played by the speaker assembly 100, so that the audio played by the speaker assembly 100 is linked with the audio played by the other speakers of the sound system in different frequency ranges, so that the vehicle audio is used as a part of the audio system, so as to create a better audio playback effect in the car, and prevent the audio played by the speaker assembly 100 of the vehicle audio from destroying the original audio playback effect in the car.

[0040] Step S300 , when it is determined that the speaker assembly 100 is not electrically connected to the sound system, it is determined whether the wireless communication module 200 is wirelessly connected to the mobile terminal.

[0041] When it is determined that the speaker assembly 100 of the car audio is not connected to the audio system, it proves that the driver and passenger expects to listen to audio outside the car, and removes the car audio and carries it to any location, so the audio system cannot transmit the audio signal to the car audio. It is then necessary to determine whether the driver and passenger use a mobile terminal to establish a wireless connection with the wireless communication module 200 of the car audio, so that the driver and passenger can use the mobile terminal to transmit the audio signal to the car audio, so that the car audio plays the corresponding audio signal outside the car.

[0042] Step S400, when it is determined that the wireless communication module 200 establishes a wireless connection with the mobile terminal, the wireless communication module 200 is controlled to receive a second audio signal from the mobile terminal and transmit it to the speaker assembly 100, the second audio signal has a second frequency range, and the second frequency range includes the first frequency range.

[0043] When it is determined that the wireless communication module 200 establishes a wireless connection with the driver's mobile terminal, the driver can use the mobile terminal to transmit the second audio signal to the wireless communication module 200 of the vehicle audio system, and the wireless communication module 200 processes the second audio signal and transmits it to the speaker assembly 100, so that the speaker assembly 100 can play the second audio signal. Since the vehicle audio system plays the second audio signal independently, the audio played by the vehicle audio system does not need to be limited to a smaller frequency range, so the second frequency range of the second audio signal is greater than the first frequency range, and the first frequency range is a subset of the second frequency range.

[0044] When the speaker assembly 100 of the car audio is connected to the vehicle's audio system, the car audio can serve as a part of the audio system and play a first audio signal in a first frequency range, limiting the frequency range of the audio played by the car audio to prevent the audio played by the car audio from affecting the overall sound effect of the audio system.

[0045] When the speaker assembly 100 of the car audio is not connected to the vehicle audio system, the car audio is wirelessly connected to the mobile terminal through the wireless communication module 200, so that the speaker assembly 100 of the car audio plays the second audio signal of the second frequency range sent by the mobile terminal, and the first frequency range is a subset of the second frequency range, so that the car audio can play more audio of other frequencies after being separated from the vehicle's audio system, so that the driver and passengers can obtain better audio sound effects outside the car.

[0046] In some embodiments, reference Figure 2 and Figure 3 As shown, the speaker assembly 100 is provided with a first speaker 110 and a second speaker 120 .

[0047] Step S200, controlling the speaker assembly 100 to receive a first audio signal transmitted by the sound system, includes the following steps.

[0048] Step S210: controlling the first speaker 110 to play a first audio signal.

[0049] After the car audio system is connected to the vehicle's audio system, the operating frequency range of the first speaker 110 is limited to the first frequency range of the first audio signal, thereby ensuring that a better audio playback effect is formed between the first audio signal played by the first speaker 110 and the remaining speakers of the speaker system.

[0050] Step S400, controlling the wireless communication module 200 to receive the second audio signal of the mobile terminal and transmitting it to the speaker assembly 100, includes the following steps.

[0051] Step S401 , controlling the first speaker 110 and the second speaker 120 to play a second audio signal, and controlling the working frequency range of the first speaker 110 to be staggered with the working frequency range of the second speaker 120 .

[0052] When the car audio system is not connected to the vehicle's audio system and the wireless communication module 200 of the car audio system is wirelessly connected to the driver's mobile terminal, the car audio system plays the second audio signal sent by the mobile terminal, and the second frequency range of the second audio signal is relatively large. Therefore, the first speaker 110 and the second speaker 120 are set to play the second audio signal at the same time, and the operating frequency ranges of the first speaker 110 and the second speaker 120 need to be staggered. The second audio signal is divided into audio in two frequency ranges through a crossover, and then transmitted to the first speaker 110 and the second speaker 120 respectively, so that the first speaker 110 and the second speaker 120 can play audio in different frequency ranges to improve the audio playback effect.

[0053] In some embodiments, the speaker assembly 100 is further provided with a third speaker 130 .

[0054] Reference Figure 3 As shown, step S400, controlling the wireless communication module 200 to receive the second audio signal of the mobile terminal and transmitting it to the speaker assembly 100, also includes the following steps.

[0055] Step S410, controlling the first speaker 110, the second speaker 120 and the third speaker 130 to play the second audio signal, and controlling the working frequency ranges of the first speaker 110, the second speaker 120 and the third speaker 130 to be staggered.

[0056] When the car audio system is not connected to the vehicle's audio system and the wireless communication module 200 of the car audio system is wirelessly connected to the driver's mobile terminal, the car audio system plays the second audio signal sent by the mobile terminal, staggers the operating frequency ranges of the first speaker 110, the second speaker 120, and the third speaker 130, and divides the second audio signal into audios in three frequency ranges through a frequency divider, which are then transmitted to the first speaker 110, the second speaker 120, and the third speaker 130 respectively, so that the three speakers can play audios in different frequency ranges, thereby further improving the audio playback effect.

[0057] In some embodiments, reference Figure 2 As shown, step S210, controlling the first speaker 110 to play the first audio signal, also includes the following steps.

[0058] Step S220, controlling the operating frequency range of the first speaker 110 to be 20 Hz to 250 Hz.

[0059] When the speaker assembly 100 of the vehicle audio system is connected to the vehicle audio system, the first speaker 110 plays the first audio signal in the bass frequency range, so that the vehicle audio system can be used as a bass speaker in conjunction with the audio system.

[0060] Reference Figure 3 As shown, step S410 controls the first speaker 110, the second speaker 120 and the third speaker 130 to play the second audio signal, and also includes the following steps.

[0061] Step S420, controlling the operating frequency range of the first speaker 110 to be 20 Hz to 250 Hz, controlling the operating frequency range of the second speaker 120 to be 250 Hz to 2000 Hz, and controlling the operating frequency range of the third speaker 130 to be 2000 Hz to 20000 Hz.

[0062] When the car audio system is not connected to the vehicle's audio system and the wireless communication module 200 of the car audio system is wirelessly connected to the driver's mobile terminal, the first speaker 110 is a bass speaker, the second speaker 120 is a mid-range speaker, and the third speaker 130 is a treble speaker, so that the car audio system can play audio in the entire range, so as to adapt to the second audio signal sent by the mobile terminal used by the driver and passenger, so that the driver and passenger can also obtain better audio playback effects outside the car.

[0063] In some embodiments, the vehicle audio system is further provided with a first power source 300 .

[0064] Reference Figure 4 As shown, the control method also includes the following steps.

[0065] Step S310 , after determining that the speaker assembly 100 is not connected to the audio system, controlling the first power supply 300 to start, and controlling the first power supply 300 to supply power to the wireless communication module 200 and the speaker assembly 100 .

[0066] After determining that the speaker assembly 100 of the car audio is not connected to the vehicle's audio system, it is proved that the driver and passengers expect to use the car audio outside the car, so it is necessary to start the first power supply 300 to power the internal components of the car audio to ensure the normal operation of the car audio. The first power supply 300 supplies electrical energy to the speaker assembly 100 and the wireless communication module 200, so that the wireless communication module 200 can be started and wirelessly connected to the mobile terminal, so that the speaker assembly 100 can be started and play the second audio signal transmitted by the mobile terminal.

[0067] In some embodiments, the first power source 300 is provided with a charging interface 310 and a discharging interface 320 , wherein the charging interface 310 is used to electrically connect to an external power source, and the discharging interface 320 is used to electrically connect to the first power-consuming device.

[0068] Reference Figure 4 As shown, the control method also includes the following steps.

[0069] Step S320 , determining whether the discharge interface 320 is electrically connected to the first electrical device, and when it is determined that the discharge interface 320 is electrically connected to the first electrical device, controlling the first power supply 300 to supply power to the first electrical device.

[0070] When the first electrical device is connected to the discharge interface 320 of the first power supply 300, the first power supply 300 supplies electrical energy to the first electrical device, so that the first power supply 300 of the car audio can be used to charge or power the first electrical device of the driver and passenger, making it convenient for the driver and passenger to use the first electrical device.

[0071] Step S330 , determining whether the charging interface 310 is electrically connected to the external power source. When it is determined that the charging interface 310 is electrically connected to the external power source, controlling the first power source 300 to receive power supply from the external power source.

[0072] When an external power source is connected to the charging interface 310 of the first power source 300 , the first power source 300 turns on the charging mode so that the electric energy of the external power source can charge the first power source 300 , so that the driver and passengers can continue to use the vehicle audio system.

[0073] In some embodiments, the vehicle audio system is also provided with a wireless charging transmitter module 400, which is electrically connected to the first power source 300, and the second power-consuming device has a wireless charging receiving module. After the wireless charging transmitter module 400 establishes an inductive connection with the wireless charging receiving module, the first power source 300 can supply power to the second power-consuming device.

[0074] Reference Figure 4 As shown, the control method also includes the following steps.

[0075] Step S340, determining whether the wireless charging transmitting module 400 is inductively connected to the wireless charging receiving module. When it is determined that the wireless charging transmitting module 400 is inductively connected to the wireless charging receiving module, controlling the first power supply 300 to supply power to the second power-consuming device through the wireless charging transmitting module 400 and the wireless charging receiving module.

[0076] When it is determined that the speaker assembly 100 of the car audio is not connected to the vehicle's audio system, proving that the driver and passenger expect to use the car audio outside the vehicle, the driver and passenger's second power-consuming device can be placed in the sensing area of ​​the wireless charging transmitter module 400, so that the wireless charging transmitter module 400 establishes an inductive connection with the wireless charging receiving module, and the first power supply 300 can supply power to the second power-consuming device.

[0077] In some embodiments, the vehicle is provided with a second power source, and the second power source is detachably electrically connected to the first power source 300 of the vehicle audio system.

[0078] Reference Figure 5 As shown, the control method also includes the following steps.

[0079] Step S500, determining whether the first power source 300 is electrically connected to the second power source.

[0080] It is necessary to determine whether the first power source 300 of the vehicle audio system is connected to the second power source of the vehicle to determine whether the second power source of the vehicle is charging the first power source 300 of the vehicle audio system.

[0081] In step S600, when it is determined that the first power source 300 is electrically connected to the second power source, the first power source 300 is controlled to receive power supply from the second power source.

[0082] When it is determined that the first power source 300 is connected to the second power source, the first power source 300 is controlled to switch to a charging mode so that the second power source charges the first power source 300.

[0083] In some embodiments, the vehicle audio system is further provided with a housing and an ambient light 500 , and the ambient light 500 is provided on the housing.

[0084] The control method also includes the following steps.

[0085] S430 , when it is determined that the wireless communication module 200 has established a wireless connection with the mobile terminal, the atmosphere light 500 is controlled to start.

[0086] An ambient light 500 is provided outside the shell of the vehicle audio system. When it is determined that the vehicle audio system is not connected to the vehicle audio system and the wireless communication module 200 is wirelessly connected to the mobile terminal, the ambient light 500 can be turned on to provide lighting or create an atmosphere for the drivers and passengers outside the vehicle.

[0087] In addition, an embodiment of the present invention further provides a vehicle audio control device, comprising: at least one processor; and a memory storing instructions, which, when executed by at least one processor, executes the vehicle audio control method of the above embodiment.
