After the portable audio device and vehicle head unit are connected via vehicle head unit Bluetooth, the vehicle head unit cannot continue to connect to mobile terminal devices such as mobile phones. The whole vehicle music is dominated by the Bluetooth device, resulting in the vehicle head unit being unable to play audio data on mobile terminal devices such as mobile phones, and can only play vehicle head unit online music or vehicle head unit local music. Therefore, how to enable the vehicle head unit to connect to mobile terminal devices such as mobile phones when the portable audio device is connected to the vehicle head unit is a technical problem that needs to be solved urgently.

[0087] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0088] In the description of this application, it should be understood that the terms "upper", "lower", "left", "right", "front", "back", "inside", "outside", etc. indicate directions or positional relationships based on the directions or relative positional relationships shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on this application. Unless otherwise specified, the above-mentioned directional description can be flexibly set in the process of actual application under the condition that the relative positional relationship shown in the accompanying drawings is met.

[0089] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, unless otherwise specified, "plurality" means two or more.

[0090] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection. It can be directly connected, or indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0091] In the present application, the terms "comprises", "comprising" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, article or device including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, article or device. In the absence of further restrictions, an element defined by the sentence "comprising a ..." does not exclude the presence of other identical elements in the process, article or device including the element.

[0092] In the embodiments of the present application, words such as "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in the embodiments of the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0093] In the description of this application, unless otherwise specified, " / " means "or", for example, A / B can mean A or B. "And / or" in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, "at least one" means one or more, and "multiple" means two or more.

[0094] At present, portable audio devices and vehicle head units can only be connected wirelessly via the vehicle head unit's Bluetooth. After the portable audio device is connected to the vehicle head unit via the vehicle head unit's Bluetooth, the vehicle head unit cannot continue to connect to mobile terminal devices such as mobile phones. The entire vehicle's music is focused on by the Bluetooth device, causing the vehicle head unit to be unable to play audio data on mobile terminal devices such as mobile phones, and can only play the vehicle head unit's online music or local music. In addition, after the portable audio device is connected to the vehicle head unit, the vehicle head unit cannot send audio data to the portable audio device, the portable audio device cannot play the same audio source as the vehicle audio device, and it is impossible for the vehicle audio device and the portable audio device to make sound together when singing karaoke.

[0095] In response to the above problems, an embodiment of the present application provides an audio control method, which establishes a wireless communication connection between a vehicle-mounted communication device and a portable audio device based on the address information of the portable audio device, so as to send audio data to the portable audio device, thereby avoiding the portable audio device and the vehicle-mounted host being connected via the vehicle-mounted Bluetooth, so that the vehicle-mounted host can be connected to a mobile terminal device such as a mobile phone via the vehicle-mounted Bluetooth, so that the vehicle-mounted host can play audio data on a mobile terminal device such as a mobile phone.

[0096] For ease of understanding, the audio control method provided in this application is specifically introduced below with reference to the accompanying drawings.

[0097] Figure 1 A flowchart of a sound control method provided in an embodiment of the present application is shown in FIG. Figure 1 As shown, the method includes the following steps S101-S102:

[0098] S101. The vehicle-mounted communication device establishes a wireless communication connection with the portable audio device based on address information of the portable audio device.

[0099] The vehicle-mounted communication device and the portable audio device establish a connection on a first wireless frequency band, and the first wireless frequency band is different from a second wireless frequency band used by the vehicle-mounted host. The wireless communication connection includes a Bluetooth connection. It is understandable that the frequency band used by the vehicle-mounted communication device and the portable audio device to establish a wireless communication connection is different from the frequency band used by the vehicle-mounted host, so as to avoid interference and have no influence on each other.

[0100] The address information is the media access control (MAC) address of the portable audio device. The MAC address is used to uniquely identify a network interface at the data link layer. According to the MAC address of the portable audio device, the vehicle communication device can accurately transmit data and send information to the portable audio device.

[0101] In some embodiments, the wireless communication connection includes a wireless communication connection in the U band. It is understandable that establishing a wireless communication connection in the U band with the least interference can improve the communication quality.

[0102] S102: The vehicle-mounted communication device obtains audio data from the vehicle-mounted host, and sends the audio data to the portable audio device based on the wireless communication connection.

[0103] Accordingly, the portable audio device establishes a wireless communication connection with the in-vehicle communication device, and can receive audio data sent by the in-vehicle communication device based on the wireless communication connection.

[0104] In some embodiments, the in-vehicle communication device can obtain the audio data being played by the in-vehicle audio device from the in-vehicle host, and send the audio data to the portable audio device via a wireless communication connection so that the portable audio device can synchronously play the audio data.

[0105] It should be understood that the vehicle-mounted communication device establishes a wireless communication connection with the portable audio device, and transmits the audio data being played by the vehicle-mounted audio device to the portable audio device, thereby avoiding the portable audio device from being connected to the vehicle-mounted host via the vehicle-mounted Bluetooth. The vehicle-mounted host can be connected to mobile terminal devices such as mobile phones via the vehicle-mounted Bluetooth, so that the vehicle-mounted host can obtain audio data on mobile terminal devices such as mobile phones, and send the audio data to the vehicle-mounted audio device and the portable audio device for playback respectively, so that the vehicle-mounted audio device and the portable audio device can not only play the vehicle-mounted online music or vehicle-mounted local music on the vehicle-mounted host, but also play music on mobile terminal devices such as mobile phones.

[0106] In some embodiments, Figure 2 As shown, the above step S101 can be specifically implemented as the following steps S1011-S1012:

[0107] S1011. The in-vehicle communication device sends a wireless communication connection establishment request to the portable audio device based on the address information of the portable audio device. Correspondingly, the portable audio device receives the wireless communication connection establishment request sent by the in-vehicle communication device.

[0108] S1012. The portable audio device establishes a wireless communication connection with the vehicle-mounted communication device in response to the wireless communication connection establishment request, and sends a wireless communication connection response to the vehicle-mounted communication device; accordingly, the vehicle-mounted communication device receives the wireless communication connection response sent by the portable audio device.

[0109] In some embodiments, the wireless communication connection establishment request includes connection parameters and connection type of the vehicle-mounted communication device, for example, the connection parameters include: frequency hopping sequence, connection interval, etc., and the connection type is back-connection. The portable audio device can set its own connection parameters based on the connection parameters and connection type of the vehicle-mounted communication device, establish a wireless communication connection with the vehicle-mounted communication device, and reply a wireless communication connection response to the vehicle-mounted communication device.

[0110] In some embodiments, Figure 3 As shown, the above step S1011 can be specifically implemented as the following steps S1011a-S1011b:

[0111] S1011a. The vehicle-mounted communication device obtains address information of the portable audio device.

[0112] As an implementation manner of S1011a, the portable audio device may send broadcast information to the in-vehicle communication device; correspondingly, the in-vehicle communication device may receive the broadcast information sent by the portable audio device, where the broadcast information includes the address information of the portable audio device.

[0113] In some embodiments, after the portable audio device is turned on, it can send a low-power Bluetooth (Bluetooth low energy, BLE) broadcast message containing the MAC address of the portable audio device, so that the portable audio device is in a discoverable state. The vehicle-mounted communication device can scan the BLE broadcast information in the surrounding environment to obtain the MAC address of the portable audio device.

[0114] As another implementation method of S1011a, when the vehicle-mounted host and the portable audio device are connected by wire, the portable audio device can send the address information of the portable audio device to the vehicle-mounted host, so that the vehicle-mounted host sends the address information of the portable audio device to the vehicle-mounted communication device; accordingly, the vehicle-mounted communication device can receive the address information of the portable audio device sent by the vehicle-mounted host.

[0115] In some embodiments, the portable audio device can realize wired connection with the vehicle host through a universal serial bus (USB) interface. The portable audio device can upload the MAC address to the vehicle host through the USB interface, and the vehicle host can send the MAC address of the portable audio device to the vehicle communication device.

[0116] S1011b: When the address information of the portable audio device matches the pre-stored address information, the in-vehicle communication device sends a wireless communication connection establishment request to the portable audio device.

[0117] In some embodiments, the vehicle-mounted communication device may match the MAC address of the portable audio device with the address information pre-stored in the vehicle-mounted communication device, that is, determine whether the MAC address of the portable audio device exists in the MAC address pre-stored in the vehicle-mounted communication device. In the case that the MAC address of the portable audio device exists in the MAC address pre-stored in the vehicle-mounted communication device, the vehicle-mounted communication device may send a wireless communication connection establishment request to the portable audio device.

[0118] It should be noted that, in the case where the vehicle-mounted host and the portable audio device are connected by wire, the vehicle-mounted communication device may store the address information of the portable audio device obtained from the vehicle-mounted host.

[0119] It should be understood that by matching the address information of the portable audio device with the pre-stored address information, only the portable audio device that has established a wired connection with the vehicle-mounted host can establish a wireless communication connection with the vehicle-mounted communication device, thereby avoiding the vehicle-mounted communication device from mistakenly connecting to other users' portable audio devices.

[0120] In some embodiments, the portable audio device may determine whether there is a wired connection between the portable audio device and the vehicle-mounted host based on the state and voltage of an enable pin of the portable audio device.

[0121] When the portable audio device is connected to the vehicle host through a wired connection, the enable pin of the portable audio device changes from a low level to a high level, turning on the communication and audio transmission functions with the vehicle host. When the portable audio device is disconnected from the vehicle host, the enable pin of the portable audio device returns to a low level. Therefore, the portable audio device can determine whether there is a wired connection between the portable audio device and the vehicle host based on the ACC pin status of the portable audio device (i.e., the enable pin status) and whether the portable audio device is connected to a 12V voltage.

[0122] In some embodiments, a sound control method provided by an embodiment of the present application further includes the following steps:

[0123] The vehicle-mounted communication device sends information indicating a target operating frequency to the portable audio device, wherein the target operating frequency is an operating frequency at which the signal quality between the vehicle-mounted communication device and the portable audio device meets a preset quality requirement, so as to establish a wireless communication connection with the portable audio device.

[0124] Among them, the preset quality requirements include any of the following: the target operating frequency is the operating frequency with the best signal quality between the vehicle-mounted communication device and the portable audio device; the signal quality of the target operating frequency is greater than or equal to the preset signal quality threshold.

[0125] In some embodiments, the target operating frequency is within the operating frequency range of the first wireless frequency band.

[0126] In some embodiments, the vehicle-mounted communication device may carry the target operating frequency in the wireless communication connection establishment request, thereby sending the target operating frequency to the portable audio device through the wireless communication connection establishment request.

[0127] In other embodiments, the vehicle-mounted communication device may also send the target operating frequency point to the portable audio device via a wireless communication connection.

[0128] It should be noted that after the portable audio device receives the target operating frequency sent by the vehicle-mounted communication device, it can reply a frequency response to the vehicle-mounted communication device and switch to the target operating frequency. The vehicle-mounted communication device receives the frequency response from the portable audio device, updates the connection device status, and saves the target operating frequency information so as to transmit audio data to the portable audio device at the target operating frequency.

[0129] In some embodiments, the target operating frequency is determined based on the electromagnetic environment inside the vehicle and / or the electromagnetic environment outside the vehicle.

[0130] The vehicle-mounted communication device can select an ultra high frequency (UHF) wireless communication transmission operating frequency with the least electromagnetic interference in the first wireless frequency band of the vehicle-mounted communication device as the target operating frequency based on the electromagnetic environment inside the vehicle and the electromagnetic environment outside the vehicle.

[0131] In some embodiments, the above step S102 may be specifically implemented as follows: the vehicle-mounted communication device may send the audio data to the portable audio device at the target operating frequency.

[0132] The in-vehicle communication device may broadcast audio data at a target operating frequency, and the portable audio device receives the audio data broadcast by the in-vehicle communication device based on the target operating frequency.

[0133] It should be understood that when audio data is transmitted at the target working frequency, the audio data will not be focused by the Bluetooth device, which reduces the electromagnetic interference of other devices and ensures the stable transmission of audio data. In addition, the delay of audio data transmission is reduced, avoiding the problem of asynchronism between portable audio devices and car speakers.

[0134] In some embodiments, the above step S102 can also be specifically implemented as follows: the vehicle-mounted communication device receives the sound data collected by the microphone device, fuses the sound data with the audio data to obtain fused audio data, and sends the fused audio data to the portable audio device based on the wireless communication connection.

[0135] In some embodiments, the microphone device can be connected to the vehicle host through a USB interface, and the vehicle host can receive the sound data collected by the microphone device and send the sound data to the vehicle communication device. The vehicle communication device can mix the sound data with the audio data being played by the vehicle speaker to obtain fused audio data, and send the fused audio data to the portable audio device through a wireless communication connection, so that the portable audio device can play the fused audio data.

[0136] It should be noted that the vehicle-mounted communication device mixes the sound data collected by the microphone device with the audio data being played by the vehicle-mounted speaker to obtain the fused audio data, and then can send the fused audio data to the portable audio device at the target working frequency.

[0137] In some embodiments, Figure 4 As shown, a sound control method provided in an embodiment of the present application further includes the following steps:

[0138] S103: The vehicle-mounted communication device sends the fused audio data to the vehicle-mounted audio device.

[0139] In some embodiments, the vehicle-mounted communication device mixes the sound data collected by the microphone device with the audio data being played by the vehicle-mounted speaker, and after obtaining the fused audio data, the fused audio data can be sent to the vehicle-mounted host, so that the vehicle-mounted host sends the fused audio data to the vehicle-mounted audio device, so that the vehicle-mounted audio device can synchronously play the fused audio data.

[0140] It should be understood that the vehicle-mounted communication device can simultaneously send the fused audio data to the portable audio device and the vehicle-mounted audio device, so that the portable audio device and the vehicle-mounted audio device can make sound together in the karaoke mode and play the same audio data.

[0141] In some embodiments, a sound control method provided by an embodiment of the present application further includes the following steps:

[0142] The in-vehicle communication device disconnects the wireless communication connection with the portable audio device in response to the connection disconnection instruction.

[0143] In some embodiments, when the portable audio device does not need to be connected to the vehicle-mounted communication device, the user can trigger a disconnection command on the vehicle-mounted multimedia, and the vehicle-mounted multimedia sends the disconnection command to the vehicle-mounted communication device through the vehicle-mounted host. The vehicle-mounted communication device responds to the disconnection command and disconnects the wireless communication connection between the portable audio device.

[0144] It should be noted that the user may also disconnect the wireless communication connection between the portable audio device and the vehicle-mounted communication device by using a one-touch disconnect button on the portable audio device.

[0145] In some embodiments, the karaoke modes of the vehicle audio device and the portable audio device in the vehicle include: an outside-vehicle karaoke mode, a separate inside-outside-vehicle singing mode, and an inside-outside-vehicle singing mode.

[0146] When the vehicle's karaoke mode is a mode for singing together inside and outside the car, the portable audio device and the vehicle audio device jointly play the audio data in the vehicle host or mobile terminal devices such as mobile phones connected to the vehicle host through wireless communication connections and target working frequencies, and / or sound data collected by receiving devices such as microphone devices.

[0147] When the karaoke mode of the vehicle is the outdoor karaoke mode or the indoor and outdoor karaoke mode, the portable audio device and the vehicle audio device play different audio data separately. The vehicle communication device no longer sends audio data to the portable audio device, and the portable audio device can switch to other audio source input mode to play audio data from other audio sources.

[0148] It should be understood that the vehicle communication device supports establishing wireless communication connections with multiple portable audio devices at the same time, so that the vehicle communication device can send audio data to multiple portable audio devices and the vehicle audio device at the same time, so that multiple portable audio devices and the vehicle audio device can make sounds together and play the same audio data.

[0149] In some embodiments, the vehicle-mounted communication device in the embodiments of the present application includes a karaoke receiver.

[0171] S608: The portable audio device receives the audio data sent by the vehicle-mounted communication device and plays it.

[0172] S609: Determine whether to disconnect the wireless communication connection with the vehicle-mounted communication device.

[0173] S610: When the wireless communication connection with the vehicle-mounted communication device is disconnected, the portable audio device disconnects the wireless communication connection with the vehicle-mounted communication device and does not play the audio data sent by the vehicle-mounted communication device.

[0174] In the case where the wireless communication connection with the in-vehicle communication device is not disconnected, step S608 is continued.

[0175] S611: Determine whether to establish a wireless communication connection with the vehicle-mounted communication device.

[0176] When a wireless communication connection is established with the vehicle-mounted communication device, step S608 is executed.

[0177] If a wireless communication connection is not established with the vehicle-mounted communication device, step S610 is continued.

[0179] In the in-car singing mode, if the portable audio device is connected to the vehicle host by wire, the portable audio device enters the heavy bass mode. If the portable audio device is not connected to the vehicle host by wire, the portable audio device exits the heavy bass mode.

[0180] In the heavy bass mode, the portable audio device functions in concert with the vehicle audio device and plays audio data together.

[0181] In the in-car and out-of-car singing mode, the portable audio device responds to the cascade button being pressed for 2 seconds or more and enters the out-of-car karaoke mode.

[0182] In the out-of-car karaoke mode, other portable audio devices can respond to the cascade button being pressed for 2 seconds or more to enter the multi-portable audio device series mode of the slave audio device, or respond to the cascade button being pressed for 2 seconds or more again to exit the multi-portable audio device series mode of the slave audio device.

[0183] In the out-of-car karaoke mode, other portable audio devices can also respond to a single short press of the cascade button to enter the multi-portable audio device series mode of the main audio device, or respond again to a long press of the cascade button for 2 seconds or more to exit the multi-portable audio device series mode of the main audio device.

[0184] In the in-vehicle and out-of-vehicle karaoke mode, the in-vehicle communication device can respond to the first mode switching instruction, enter / exit the out-of-vehicle karaoke mode, and update the status of the portable audio device in real time.

The karaoke software in the SOC of the vehicle host is also connected to the vehicle audio device via the automotive audio bus (A2B) to play the audio data in the karaoke software.

[0189] The MCU+DSP in the vehicle communication device sends the cascaded networking BLE connection request broadcast and the target working frequency through BLE1 / BLE2, and receives the sound data of the karaoke microphone through frequency modulation broadcast (FM), and mixes the sound data of the karaoke microphone with the audio data of the vehicle system.

[0190] The MCU+DSP in the vehicle communication equipment can also broadcast voice data+audio data via UHF.
