[0054] To illustrate the technical solution of this application, the following embodiments will be used for explanation.

[0055] Example 1

[0056] Please see Figure 1 This application provides a sound enhancement method, including:

[0057] Step 101: With the car model and the vehicle having established a communication connection, detect the vehicle's audio playback status.

[0058] The aforementioned audio playback status indicates the state of audio playback. In practice, this state can include both audio playback status and audio not being played.

[0059] Here, the vehicle model is typically the implementer of the aforementioned sound enhancement method. In practice, once a communication connection has been established between the vehicle model and the vehicle, the vehicle model can detect the vehicle's audio playback status in various ways.

[0060] As an example, the model car can receive audio signals from the vehicle in real time through its onboard audio receiver. By determining the presence or absence of the received audio signal, it can ascertain whether the vehicle is playing audio. Specifically, if an audio signal is received, it is determined that the vehicle is in audio playback mode. If no audio signal is received, it is determined that the vehicle is not playing audio.

[0061] As another example, when the audio input interface of the model car is electrically connected to the audio output interface of the vehicle, the model car can detect the vehicle's audio playback status by judging the presence or absence of an electrical signal at the model car's audio input interface. Specifically, if an electrical signal is detected, it is determined that the vehicle is in audio playback mode. If no electrical signal is detected, it is determined that the vehicle is in audio non-playing mode.

[0062] As another example, the car model can also receive playback instruction information sent by the vehicle. By analyzing this information, it can detect the vehicle's audio playback status. Specifically, if the playback instruction information indicates that the vehicle is playing audio, then the vehicle is determined to be in audio playback mode. If the playback instruction information indicates that the vehicle is not playing audio, then the vehicle is determined to be in audio non-playing mode.

[0063] This embodiment uses different methods to determine whether the vehicle is playing audio, thus achieving diversity in audio recognition and improving the comprehensiveness and accuracy of audio recognition.

[0064] Step 102: When the audio playback status indicates that the vehicle is in audio playback mode, obtain the target audio being played by the vehicle.

[0065] The target audio mentioned above is typically the audio signal played by the vehicle. This audio signal is usually an information carrier of regular sound waves with varying frequencies and amplitudes, incorporating speech, music, and sound effects.

[0066] Here, when the audio playback status indicates that the vehicle is in audio playback mode, the model car can acquire the target audio being played by the vehicle. As an example, the model car can acquire the target audio from the vehicle via a network. As another example, the model car can also acquire the target audio from the vehicle via Bluetooth. As yet another example, when the model car's audio input interface is electrically connected to the vehicle's audio output interface, the model car can also directly acquire the target audio transmitted from the vehicle's audio output interface through that audio input interface.

[0067] Step 103: Based on the target communication method between the car model and the vehicle, control the car model and the vehicle to play the target audio in phase.

[0068] The aforementioned target communication method typically refers to the communication between the model car and the vehicle. In practical applications, this target communication method can be either wired or wireless.

[0069] Here, the car model can be controlled to play the target audio in phase with the vehicle based on the target communication method between the car model and the vehicle. For example, when the target communication method is wired, the car model can be controlled to directly output the target audio transmitted from the vehicle to the car model via wired connection. In this case, since the car model and the vehicle play the exact same audio at the same time and are in phase, the sound effect can be enhanced.

[0070] The sound enhancement method provided in this embodiment, when a communication connection has been established between the car model and the vehicle, allows the car model to automatically detect the vehicle's audio playback status. When the audio playback status indicates the vehicle is in audio playback mode, the car model can acquire the target audio being played by the vehicle and control the car model to play the target audio in sync with the vehicle. This allows for sound enhancement of the target audio played by the vehicle when the car model is relatively close to the vehicle. Furthermore, when the car model is placed inside the vehicle, it can both decorate the vehicle and enhance the sound of the target audio played by the vehicle. When the car model is placed around the vehicle, it can enhance the sound of the target audio played by the vehicle within a certain area around the vehicle. Additionally, the car model can automatically play the same audio content as the vehicle even when it is far away. This enriches the functionality of the car model and helps improve the user experience.

[0071] In some scenarios, the target audio played in the vehicle can originate from the vehicle itself or from other devices within the vehicle, such as a passenger's mobile phone. In this scenario, the car model can receive the target audio played in the vehicle in real-time via its onboard audio receiver; alternatively, it can receive the target audio played in the vehicle in real-time via the vehicle's audio receiver; or it can receive the target audio sent from the aforementioned other devices to the vehicle and then forwarded to the car model via a network. Subsequently, the car model, the vehicle, and the aforementioned other devices can play the target audio simultaneously, thus enhancing the sound effects of the target audio played by other devices within the vehicle.

[0072] It should be noted that the aforementioned sound enhancement method can also be implemented by a vehicle. When the implementing entity is a vehicle, and a communication connection has been established between the car model and the vehicle, the vehicle can directly obtain the vehicle's audio playback status and the target audio being played. Subsequently, the vehicle can control the car model and the vehicle to play the target audio in phase, based on the target communication method between them. For example, when the target communication method is wired, the vehicle can control the car model to directly output the target audio transmitted from the vehicle to the car model via a wired connection. In this case, since both are playing the exact same audio simultaneously, their phases can be identical, thus achieving the sound enhancement effect.

[0073] In some optional implementations of this embodiment, before step 101, the sound enhancement method may further include: detecting whether the car model is inside the vehicle.

[0074] In practice, the presence of a car model inside a vehicle can be determined in several ways. For example, it can be detected whether a charging connection has been established between the car model and the vehicle. If a charging connection is established, it can be determined that the car model is inside the vehicle. This charging connection can occur either by the car model being located within the vehicle's wireless charging area or by the car model's charging port being electrically connected to the vehicle's power output port. When the car model is inside the vehicle, playing the target audio in sync with the vehicle can enhance the sound effects of the target audio being played by the vehicle.

[0075] In some alternative implementations, the above-mentioned detection of whether the car model is inside the vehicle may include at least one of the following steps one and two.

[0076] Step 1: Obtain the scene image of the current scene and perform scene recognition on the scene image to obtain the recognition result. If the recognition result indicates that the current scene is a vehicle scene, then it is determined that the car model is in the vehicle.

[0077] The aforementioned current scene is typically the scene where the car model is currently located.

[0078] Here, the car model can capture an image of the current scene using a camera on its body. The model can then perform scene recognition on this image; for example, it can match the image with pre-stored vehicle scene images to obtain a recognition result. This result indicates whether the current scene is a vehicle scene. When the recognition result indicates that the current scene is a vehicle scene, it can be determined that the car model is currently inside a vehicle.

[0079] Step 2: Check the hardware access status of the preset hardware interface of the car model. When the hardware access status indicates that there is external hardware connected to the preset hardware interface of the car model, it is determined that the car model is in the vehicle.

[0080] The aforementioned preset hardware interface can be a pre-defined hardware interface on the car model. As an example, the preset hardware interface can be a charging port, headphone jack, etc.

[0081] Here, since the voltage level at the preset hardware interface of the car model usually changes when hardware is connected, the hardware connection status of the preset hardware interface of the car model can be detected. When the hardware connection status indicates that external hardware is connected to the preset hardware interface of the car model, it can be determined that the car model is currently in a vehicle.

[0082] In practice, the model car can accurately determine whether it is inside the vehicle by performing at least one of the steps one and two above.

[0083] In some optional implementations of this embodiment, before step 101, the sound enhancement method may further include: when the car model is in the vehicle, detecting whether the car model has established a communication connection with the vehicle.

[0084] Here, the car model can determine whether a communication connection has been established with the vehicle in several ways. For example, the car model can send a preset interactive message to the vehicle. If the car model receives a response from the vehicle based on the preset interactive message within a preset time period, the car model can determine that a communication connection has been established with the vehicle. The preset interactive message is usually pre-set information, such as "ask," or other forms of information. The preset time period is usually a pre-set duration, such as 1 minute.

[0085] In some alternative implementations, the above-mentioned detection of whether the vehicle model has established a communication connection with the vehicle may include at least one of the following first and second items.

[0086] The first step is to ensure that a wired communication connection has been established between the car model and the vehicle when there is external hardware connected to the preset hardware interface of the car model.

[0087] The aforementioned preset hardware interface can be a pre-defined hardware interface on the car model. As an example, the preset hardware interface can be a charging port, headphone jack, etc.

[0088] Here, when external hardware is connected to the model car's preset hardware interface, the model car can be considered to have established a communication connection with the vehicle, and this communication connection is a wired communication connection. It should be noted that when a wired communication connection is established between the model car and the vehicle, the communication method between the model car and the vehicle is a wired communication method.

[0089] The second step is to control the car model to establish a wireless communication connection with the vehicle using a target wireless communication method.

[0090] The aforementioned target wireless communication methods are typically those supported by both the car model and the vehicle itself. These target wireless communication methods may include, but are not limited to, Bluetooth communication and WiFi communication.

[0091] Here, when the model car determines that no external hardware is connected to the aforementioned preset hardware interface, it can determine that no wired communication connection has been established between the model car and the vehicle. In this case, the model car can control itself to establish a wireless communication connection with the vehicle using the target wireless communication method. In practice, when there are multiple target wireless communication methods, the model car can attempt to establish a communication connection with the vehicle according to the priority of each target wireless communication method.

[0092] For example, if there are two target wireless communication methods, Bluetooth and WiFi, and Bluetooth has a higher priority than WiFi, the model car can first attempt to establish a connection with the vehicle via Bluetooth. If the connection is successful, the model car can confirm that a wireless communication connection has been established with the vehicle, and the wireless communication method at this point is Bluetooth. Alternatively, if the model car attempts to establish a connection via Bluetooth but fails, it can select WiFi to continue attempting to establish a connection. If the connection is successful, the model car can confirm that a wireless communication connection has been established with the vehicle, and the wireless communication method at this point is WiFi.

[0093] In practice, the car model can accurately determine whether a communication connection has been established between the car model and the vehicle by performing at least one of the first and second items mentioned above.

[0094] See Figure 2 , Figure 2 This is a structural schematic diagram of a vehicle provided in an embodiment of this application. Figure 2 As shown, the vehicle may include a first wireless communication device, a vehicle control device, a first audio processing device, and a first audio playback device that are electrically connected in sequence.

[0095] The first wireless communication device includes at least one of the following: a first Bluetooth device and a first wireless access device. The wireless communication device is typically used to implement wireless communication, and may include one or more devices simultaneously; for example, it may include both a Bluetooth device and a wireless access device. The aforementioned wireless access device is used to access a wireless network, such as a WiFi hotspot.

[0096] It should be noted that the terms "first," "second," etc., used in this application are only for distinguishing descriptions. For example, "first wireless communication device" refers to a specific wireless communication device, while "second wireless communication device" usually refers to another wireless communication device.

[0097] In practice, the aforementioned vehicle control device can be a system on a chip (SoC), the aforementioned first audio processing device can be a digital signal processor (DSP), and the aforementioned first audio playback device can be a speaker.

[0098] In practical applications, the vehicle may further include a first power amplifier, through which the first audio processing device can be connected to the first audio playback device. By placing the first power amplifier between the first audio processing device and the first audio playback device, the sound quality of the audio output by the vehicle can be improved.

[0099] See Figure 3 , Figure 3 This is a schematic diagram of the structure of a car model provided in an embodiment of this application. Figure 3 As shown, the car model may include a second audio processing device and a second wireless communication device, an audio receiving device, and a second audio playback device electrically connected to the second audio processing device.

[0100] The second wireless communication device is compatible with the first wireless communication device, and the first audio processing device and the second audio processing device can be connected via a wired connection. The second wireless communication device includes at least one of the following: a second Bluetooth device and a second wireless access device. In practice, compatibility between the second and first wireless communication devices typically means that they can cooperate to establish a wireless communication connection. For example, if both the first and second wireless communication devices include a first Bluetooth device, they can cooperate to establish a wireless communication connection; in this case, they are compatible. However, if both the first and second wireless communication devices include a first Bluetooth device, they cannot cooperate to establish a wireless communication connection; in this case, they are not compatible.

[0101] In practice, the aforementioned second audio processing device can be a DSP, the aforementioned audio receiving device can be a microphone, and the aforementioned second audio playback device can be a speaker.

[0102] In practical applications, the aforementioned car model may also include a second power amplifier, through which the second audio processing device is connected to the second audio playback device. Placing the second power amplifier between the second audio processing device and the second audio playback device can improve the sound quality of the audio output by the car model.

[0103] In some implementations, obtaining the target audio played by the vehicle may include obtaining the target audio through a target device in the vehicle model.

[0104] The target device corresponds to the target communication method, and the target device includes: a second audio processing device, an audio receiving device, and a second wireless communication device.

[0105] In practice, when the target communication method is wired communication, the target device can be a second audio processing device. When the target communication method is wireless communication, the target device can be an audio receiving device and a second wireless communication device.

[0106] Here, the car model can acquire target audio through the target device corresponding to the target communication method, thereby accurately knowing the target device used to acquire the target audio at the same time as acquiring the target audio, which helps to accurately and effectively process and output the acquired target audio.

[0107] In some implementations, controlling the car model and the vehicle to play the target audio in sync based on the target communication method between the car model and the vehicle may include the following first and second steps.

[0108] The first step is to control the second audio processing device to output the target audio to the second audio playback device if the target communication method is wired communication and the target device is the second audio processing device.

[0109] Here, when the target communication method is wired communication, the target device is the second audio processing device. In this case, the car model can directly output the target audio to the second audio playback device by controlling the second audio processing device in the car model. This allows the second audio playback device of the car model and the first audio playback device of the vehicle to play the target audio simultaneously, thereby achieving synchronized playback of the target audio between the car model and the vehicle. Since both play the exact same audio simultaneously, their phases can be identical, which helps to enhance the sound effects.

[0110] The second step involves, if the target communication method is wireless communication and the target device is an audio receiving device and a second wireless communication device, then the second audio processing device controlling the vehicle model performs audio phase calibration on the audio received by the audio receiving device, obtains the target audio, and outputs the target audio to the second audio playback device.

[0111] Here, for ease of description, the audio received by the audio receiving device can be referred to as the first audio, and the audio received by the second wireless communication device can be referred to as the second audio. The aforementioned audio phase calibration is used to adjust the phase of the second audio to be the same as the phase of the first audio.

[0112] Here, when the target communication method is wireless communication, the target device is an audio receiving device and a second wireless communication device. In this case, the car model can control the second audio processing device in the car model to perform phase calibration on the second audio using the first audio, so that the car model and the vehicle can output the target audio in phase. When both devices play a certain audio in phase simultaneously, sound effect enhancement can be achieved on the played target audio.

The target device corresponds to a target communication method and includes: a second audio processing device, an audio receiving device, and a second wireless communication device.

[0125] In some embodiments, the playback control unit 403 is specifically configured to: if the target communication method is wired communication and the target device is a second audio processing device, control the second audio processing device of the vehicle model to output the target audio to the second audio playback device. If the target communication method is wireless communication and the target device is an audio receiving device and a second wireless communication device, control the second audio processing device of the vehicle model to perform audio phase calibration on the audio received by the second wireless communication device based on the audio received by the audio receiving device to obtain the target audio, and output the target audio to the second audio playback device.

[0126] The device provided in this embodiment, when a communication connection has been established between the car model and the vehicle, allows the car model to automatically detect the vehicle's audio playback status.

[0128] Example 3

[0129] Continue to refer to Figure 5 , Figure 5 This is a schematic diagram of the sound enhancement system provided in an embodiment of this application. Figure 5 As shown, the sound enhancement system may include a vehicle 501 and a vehicle model 502 that is communicatively connected to the vehicle 501.

[0130] The vehicle 501 includes a first wireless communication device, a vehicle control device, a first audio processing device, and a first audio playback device that are connected in sequence. The first wireless communication device includes at least one of the following: a first Bluetooth device and a first wireless access device.

[0131] The car model 502 includes a second audio processing device and a second wireless communication device, an audio receiving device, and a second audio playback device electrically connected to the second audio processing device. The second wireless communication device is adapted to the first wireless communication device, and the first audio processing device and the second audio processing device can be wired connected. The second wireless communication device includes at least one of the following: a second Bluetooth device and a second wireless access device.

[0132] The second audio processing device of the car model 502 is used to detect the audio playback status of the vehicle 501 when the car model 502 and the vehicle 501 have established a communication connection; when the audio playback status indicates that the vehicle 501 is in the audio playback state, it acquires the target audio played by the vehicle 501; and according to the target communication method between the car model 502 and the vehicle 501, it controls the car model 502 and the vehicle 501 to play the target audio in phase.

[0133] like Figure 5 As shown, the first wireless communication device in vehicle 501 can establish a wireless communication connection with the second wireless communication device in vehicle model 502. The audio receiving device in vehicle model 502 can receive audio played by the first audio playback device in vehicle 501. The first audio processing device in vehicle 501 can establish a wired connection with the second audio processing device in vehicle model 502.

[0134] In this embodiment, when a communication connection has been established between the car model and the vehicle, the car model can automatically detect the vehicle's audio playback status. When the audio playback status indicates that the vehicle is in audio playback mode, the car model can acquire the target audio being played by the vehicle and control the car model to play the target audio in sync with the vehicle. This allows for sound effect enhancement of the target audio played by the vehicle when the car model is relatively close to the vehicle. Furthermore, when the car model is placed inside the vehicle, it can both decorate the vehicle and enhance the sound effects of the target audio played by the vehicle. When the car model is placed around the vehicle, it can enhance the sound effects of the target audio played by the vehicle within a certain area around the vehicle. Additionally, the car model can automatically play the same audio content as the vehicle even when it is far away from the vehicle. This enriches the functionality of the car model and helps improve the user experience.

[0135] In some optional implementations of this embodiment, the target audio is played in phase between the car model and the vehicle according to the target communication method between them. This includes: if the target communication method is wired communication and the target device is a second audio processing device, then the second audio processing device of the car model is controlled to output the target audio to a second audio playback device. If the target communication method is wireless communication and the target device is an audio receiving device and a second wireless communication device, then the second audio processing device of the car model is controlled to perform audio phase calibration on the audio received by the second wireless communication device based on the audio received by the audio receiving device to obtain the target audio, and then output the target audio to the second audio playback device.

[0136] For ease of description, the audio received by the audio receiving device can be referred to as the first audio, and the audio received by the second wireless communication device can be referred to as the second audio. The aforementioned audio phase calibration is used to adjust the phase of the second audio to be the same as the phase of the first audio.

[0137] Here, when the target communication method is wired communication, the target device is the second audio processing device. In this case, the car model can directly output the target audio to the second audio playback device by controlling the second audio processing device in the car model. This allows the second audio playback device of the car model and the first audio playback device of the vehicle to play the target audio simultaneously, thereby achieving synchronized playback of the target audio between the car model and the vehicle. Since both play the exact same audio simultaneously, their phases can be identical, which helps to enhance the sound effects.

[0138] When the target communication method is wireless communication, the target device is an audio receiving device and a second wireless communication device. In this case, the car model can control the second audio processing device in the car model to perform phase calibration on the second audio using the first audio, so that the car model and the vehicle can output the target audio in phase. When both devices play a certain audio in phase simultaneously, sound effect enhancement can be achieved on the played target audio.

[0139] It should be noted that the information interaction and execution process between the car model and the vehicle mentioned above are based on the same concept as the method embodiment of this application. For details on their specific functions and technical effects, please refer to the method embodiment section, which will not be repeated here.
