Description

Technical Field

[0001] This application belongs to the field of vehicle technology, and in particular relates to an audio system, a control method for the audio system, and a vehicle. Background Technology

[0002] Currently, with the increasing popularity of vehicles, existing vehicles can be equipped with audio systems for users.

[0003] However, existing vehicle audio systems all reuse the vehicle's existing audio system to mix vocals and accompaniment before playback. This necessitates a strong correlation and coupling between the audio system and the vehicle's existing system, limiting its usability. Summary of the Invention

[0004] The purpose of this application is to provide an audio system, a control method for the audio system, and a vehicle, which can be applied to more usage scenarios without strong correlation and coupling with the vehicle's audio system.

[0005] A first aspect of this application provides an audio system, comprising:

[0006] First docking station;

[0007] The first speaker device is detachably connected to the first docking station. The first speaker device includes a first receiving unit, a first processing module, and at least one first speaker. The first receiving unit is used to receive a first signal. The first processing module is signal-connected to the first receiving unit, and the output terminal of the first processing module is signal-connected to the first speaker.

[0008] This application provides an audio system in which a first speaker device includes a first receiving unit, a first processing module, and a first speaker. This enables the first speaker device to receive and process audio signals and play audio through the first speaker. In other words, the first speaker device can operate independently without relying on a first docking station. It can receive and play audio signals from the first docking station, as well as audio signals from other devices, reducing limitations on its use. Furthermore, the first speaker device is detachably connected to the first docking station, allowing it to be removed and moved to other locations, making it suitable for a wider range of applications.

[0009] A second aspect of this application provides a control method for an audio system, applied to the audio system provided in the first aspect above, the method comprising:

[0010] The first receiving unit receives the first signal;

[0011] The first receiving unit outputs first data to the first processing module based on the first signal;

[0012] The first processing module outputs the first audio value to the first speaker based on the first data;

[0013] The first speaker plays the first audio.

[0014] A third aspect of this application provides a vehicle that includes the audio system provided in the first aspect.

[0015] It is understandable that the beneficial effects of the third aspect mentioned above can be found in the relevant descriptions in the first aspect above, and will not be repeated here. Attached Figure Description

[0023] Karaoke is currently a popular form of entertainment, enjoyed by many. It can be done both at home and outdoors. Furthermore, with increasing vehicle ownership, many vehicles are now equipped with audio systems for karaoke enjoyment.

[0024] However, existing vehicle audio systems all reuse the vehicle's existing audio system to mix vocals and accompaniment before playback. This necessitates a strong correlation and coupling between the audio system and the vehicle's existing system, limiting its usability.

[0025] To address the aforementioned technical issues, this application provides an audio system that does not require strong association and coupling with the vehicle's audio system, making it suitable for a wider range of applications.

[0026] See Figure 1 , Figure 1 A schematic diagram of the structure of an audio system provided in an embodiment of this application is shown.

[0027] For ease of explanation, only the parts relevant to this embodiment are shown, and are described in detail below:

[0028] exist Figure 1 In the present invention, an audio system 100 includes a first docking station 10 and a first speaker device 20. The first speaker device 20 is detachably connected to the first docking station 10. The first speaker device 20 includes a first receiving unit 201, a first processing module 202 and at least one first loudspeaker 203. The first receiving unit 201 is used to receive a first signal. The first processing module 202 is signal-connected to the first receiving unit 201. The output terminal of the first processing module 202 is signal-connected to the first loudspeaker 203.

[0029] Understandably, the first speaker device 20 includes a first receiving unit 201, a first processing module 202, and a first speaker 203, enabling it to receive and process audio signals and play them through the first speaker 203. In other words, the first speaker device 20 can operate independently of the first docking station 10. It can receive and play audio signals from the first docking station 10, as well as audio signals from other devices, reducing limitations on its use. Furthermore, the first speaker device 20 is detachably connected to the first docking station 10, allowing it to be removed and moved to other locations, making it suitable for a wider range of applications.

[0030] In this embodiment, the first speaker device 20 is detachably disposed on the first docking station 10, which means that the first speaker device 20 can be installed on the first docking station 10 and used in conjunction with the audio system of the first docking station 10, or it can be detached from the first docking station 10 and used independently.

[0031] In some examples, the first signal generally refers to the sound signal collected by the first receiving unit 201. Here, the sound signal can specifically be the sound of the user during the use of the audio system, that is, the human voice signal.

[0032] In some examples, the first receiving unit 201 is, for example, a U-band signal receiving chip, and the first processing module 202 is, for example, a DSP chip.

[0033] In some examples, the first docking station 10 can be a vehicle or a chip on a vehicle. In a specific implementation, the vehicle can be equipped with a storage space to accommodate the first speaker device 20, such as a speaker storage compartment, a speaker storage recess, or a speaker storage cavity. Correspondingly, the first speaker device 20 can be configured with a shape and structure that matches the storage space, allowing it to be completely embedded within it. Here, the storage space can be located anywhere within the vehicle's cabin, such as in the door, driver's seat, rear seats, or seat armrests.

[0034] As one possible implementation, a first contact electrode can be provided within the storage space, and a second contact electrode that cooperates with the first contact electrode can be provided on the first speaker device 20. Thus, when the first speaker device 20 is placed in the storage space, it establishes an electrical connection with the vehicle's audio system through the second contact electrode and the first contact electrode in the storage space. In this case, the first speaker device 20 can function as a speaker for the vehicle's audio system. When the first speaker device 20 is removed from the storage space, the second contact electrode disconnects from the first contact electrode. At this time, since the first speaker device 20 can still receive signals through the first receiving unit 201, it can receive audio signals sent by the vehicle or other devices. That is, when the first speaker device 20 is taken out and used independently, it can receive and play audio signals in real time.

[0035] As one possible implementation, the first speaker device 20 can be equipped with an independent switch. When the first speaker device 20 is not installed in the vehicle, the user can turn it on or off by triggering the switch. When the first speaker device 20 is installed back into the vehicle, if the user does not manually turn it off, the first speaker device 20 will detect that its second contact electrode is in contact with the vehicle's first contact electrode, thus confirming that it is installed back in the vehicle and automatically triggering a shutdown operation.

[0036] The above-described solution provides an audio system including a first speaker device 20. Since the first speaker device 20 is detachably mounted in the vehicle and has signal receiving capabilities, it can receive audio signals without relying on the vehicle when it is not mounted. When the first speaker device 20 is mounted in the vehicle, it can be used in conjunction with the vehicle's audio system. This achieves compatibility between the audio system and the vehicle while avoiding limitations imposed by the vehicle's usage scenarios, thus broadening the system's applicability.

[0037] Figure 2 A schematic diagram of the structure of an audio system according to another embodiment of this application is shown. Figure 2 As shown, in another embodiment, the first processing module 202 includes a first processing unit 2021 and a first power amplifier unit 2022. The first processing unit 2021 is signal-connected to the first receiving unit 201, the input terminal of the first power amplifier unit 2022 is signal-connected to the first processing unit 2021, and the output terminal of the first power amplifier unit 2022 is signal-connected to the first speaker 203.

[0038] Understandably, after receiving the first signal, the first receiving unit 201 will transmit the first signal to the first processing unit 2021. The first processing unit 2021 will process the first signal and then transmit it to the first power amplifier unit 2022. The first power amplifier unit 2022 will amplify the processed first signal and then output the amplified sound through the first speaker 203, so that the first speaker device 20 has the functions of receiving and emitting sound. The first speaker device 20 can be used independently of the first docking station 10, reducing the limitations on the use of the first speaker device 20.

[0039] In some embodiments, the frequency range of the first signal is between 430 MHz and 440 MHz. It is understood that setting the frequency range of the first signal between 430 MHz and 440 MHz allows the first speaker device 20 to receive audio signals smoothly and also avoids interference from signals such as Bluetooth pairing signals.

[0040] Meanwhile, signals with frequencies between 430 MHz and 440 MHz have the characteristic of fast propagation speed, allowing the first speaker device 20 to quickly receive audio signals and respond quickly. That is, the first speaker device 20 can quickly receive the first signal and play it through the first speaker, improving the response speed of the audio system. For example, when the audio system is used for karaoke, after the user makes a sound, the first speaker device 20 can quickly receive the audio signal corresponding to the user's voice and then quickly play the user's voice through the first speaker, ensuring a good user experience.

[0041] Signals with a frequency range between 430 MHz and 440 MHz have a wide propagation range. When an audio system has two or more speaker units, all two or more speaker units can receive the first signal, allowing them to simultaneously play the first signal through loudspeakers. This avoids inconsistencies in the audio played by different speaker units and ensures the sound system's performance.

[0042] In some examples, the first signal is, for instance, a U-band signal. U-band signals have the characteristics of high propagation speed and wide propagation range, which can effectively improve the effect of the audio system.

[0043] In some embodiments, the first speaker device 20 includes a second receiving unit for receiving a second signal, and the second receiving unit is signal-connected to the first receiving unit 201.

[0044] It is understandable that the second receiving unit is communicatively connected to the first docking station 10. The second receiving unit can receive the second signal and then use the second signal to configure the information of the first receiving unit 201, thereby achieving pairing with the microphone or vehicle audio system.

[0045] In some examples, the frequency range of the second signal is between 2400 MHz and 2483.5 MHz. It is understood that setting the frequency range of the second signal between 2400 MHz and 2483.5 MHz allows the first speaker device 20 to successfully receive the second signal for pairing, and also avoids interference from signals such as microphone audio signals.

[0046] Meanwhile, signals with a frequency range between 2400 MHz and 2483.5 MHz have high transmission stability and can reliably establish a connection between the first speaker device 20 and the microphone or car audio system.

[0047] For example, the second signal is a Bluetooth signal. Bluetooth signals have high transmission stability and can reliably establish a connection between the first speaker device 20 and the microphone or car audio system.

[0048] In some embodiments, the second receiving unit is signal-connected to the first processing module 202.

[0049] It is understood that the second receiving unit can also directly transmit the received signal to the first processing module 202, which processes the signal and then plays it through the first speaker 203. In other words, this embodiment can utilize the second receiving unit to receive audio signals, thereby enabling the first speaker device 20 to have audio receiving and playback functions.

[0050] For example, the second receiving unit can be paired with the vehicle to receive accompaniment provided by the vehicle, so that the first speaker device 20 can receive the accompaniment through the second receiving unit.

[0051] It is easy to understand that, in practical use, the second signal can also be a signal used to configure the first receiving unit. Here, since the second receiving unit is signal-connected to the first receiving unit, when the second receiving unit receives the second signal, it can directly configure the second signal to the first receiving unit.

[0052] For example, the second signal is the configuration information of the microphone frequency band. When the second receiving unit receives the frequency band configuration information, it can configure the frequency band configuration information to the first receiving unit, so that the first receiving unit can receive the frequency band signal corresponding to the frequency band configuration information, that is, the first signal sent through the microphone.

[0053] In some embodiments, the first speaker device 20 includes a third receiving unit for receiving a third signal, and the third receiving unit is signal-connected to the first processing module 202.

[0054] It is understandable that the third receiving unit can receive the third signal and transmit it to the first processing module 202 for processing, so that the first processing module 202 can drive the first speaker 203 to emit sound according to the third signal.

[0055] For example, the first receiving unit 201 can receive microphone audio (i.e., human voice), the third receiving unit can receive accompaniment audio, and the first processing module 202 can mix and process the human voice and accompaniment and then play them through the first speaker 203.

[0056] Specifically, the first speaker device 20 is paired with the microphone through the first receiving unit 201. After pairing, the first receiving unit 201 receives the human voice audio signal, while the third receiving unit can receive the accompaniment audio, so that the user can sing karaoke through the first speaker device 20.

[0057] In some embodiments, the audio system includes a plurality of the first receiving stations and a plurality of the first speaker devices 20.

[0058] It is understandable that there is a one-to-one correspondence between multiple first receiving stations and multiple first speaker devices 20, meaning that each first receiving station can be detachably connected to a first speaker device 20. Each first speaker device 20 can be used in conjunction with its corresponding first receiving station, or it can be detached from the first receiving station for independent use, increasing the user's choices. Furthermore, the coordinated use of multiple first speaker devices 20 can achieve a stereo sound effect for karaoke, improving the user experience.

[0059] In some embodiments, the first speaker device 20 further includes a first transmitting unit, which is signal-connected to the first processing module 202, and is used to transmit a target signal.

[0060] The audio system also includes:

[0061] The second speaker device includes a fourth receiving unit and at least one second speaker. The fourth receiving unit is connected to the second speaker and is used to receive the target signal transmitted by the first transmitting unit.

[0062] It is understandable that the first speaker device 20 can emit a target signal through the first transmitting unit, so that the second speaker device can receive the target signal emitted by the first transmitting unit through the fourth receiving unit, thereby realizing the interconnection between the first speaker device 20 and the second speaker device. In this way, the signal at the first speaker device 20 can be transmitted to the second speaker device, so that the speaker system has the first speaker device 20 and the second speaker device. The first speaker device 20 and the second speaker device can work simultaneously, which is conducive to creating a more three-dimensional sound atmosphere.

[0063] For example, the target signal includes at least one of a first signal, a second signal, and a third signal.

[0064] Specifically, the first signal can be the human voice received by the first receiving unit 201. That is, the human voice can be played simultaneously by the first speaker 203 of the first speaker device 20 and the second speaker of the second speaker device, which is beneficial to improving the sound effect.

[0065] The second signal can be the accompaniment audio received by the first receiving unit 201. That is, the accompaniment audio can be played simultaneously by the first speaker 203 of the first speaker device 20 and the second speaker of the second speaker device, which is beneficial to improving the sound effect.

[0066] The first speaker device 20 can receive frequency band information to achieve pairing connection with the microphone, and the third signal can be the frequency band information received by the first speaker device 20, so that the second speaker device can also achieve pairing connection with the microphone. Thus, the first speaker device 20 and the second speaker device can be used simultaneously to receive and play human voice, improving the sound effect.

[0067] In some embodiments, the audio system includes at least two second speaker devices, each second speaker device including a second transmitting unit for signal connection to the fourth receiving unit of another second speaker device.

[0068] It is understood that each second speaker device includes a second transmitting unit and a fourth receiving unit. The fourth receiving unit of one second speaker device can be used to receive the target signal transmitted by the first speaker device 20. Then, one second speaker device can transmit a signal through the second transmitting unit, and the other second speaker device can receive the signal transmitted by one of the second speaker devices through the fourth receiving unit, thereby realizing the interconnection between one second speaker device and the other second speaker device. This allows the first speaker device 20 to be interconnected with at least two second speaker devices, and the first speaker device 20 and at least two second speaker devices can work simultaneously, which is beneficial to improving the stereo sound effect of the audio system.

[0069] In some embodiments, the audio system further includes:

[0070] A radio receiving device, comprising a radio receiving module and a third transmitting unit;

[0071] The third transmitting unit is signal-connected to the first receiving unit 201, and the sound receiving module is used to generate the corresponding first signal based on the collected sound signal; the third transmitting unit is used to transmit the first signal.

[0072] It is understandable that the sound receiving device can collect sound signals (such as human voices) and generate a corresponding first signal. The third transmitting unit then sends the first signal to the first receiving unit 201, so that the first processing module 202 can process the collected sound and drive the first speaker 203 to emit sound.

[0073] For example, the sound receiving device is a microphone, and the sound receiving module is a microphone receiving chip.

[0074] Understandably, since the first speaker device 20 is detachably mounted on the vehicle, and the receiver and the first speaker device 20 are connected via a first communication method, the receiver can always use the collected sound signal as the first signal and send it to the first speaker device 20, regardless of whether the first speaker device 20 is mounted on the first docking station 10. That is, the first speaker device 20 can receive the first signal sent by the receiver regardless of whether it is mounted on the first docking station 10, such as a vehicle. This achieves compatibility between the karaoke system and the vehicle while avoiding limitations imposed by the vehicle's usage scenario, thus broadening the applicability of the karaoke system.

[0075] For example, in a specific implementation, both the first speaker device 20 and the radio receiver can be configured with radio frequency modules or radio frequency circuits. By configuring a preset communication frequency band or frequency point, a first communication method connection between the two can be achieved. Here, the preset communication frequency band refers to the broadcast frequency band pre-configured by the radio receiver, through which radio frequency waves / signals carrying the first signal can be broadcast. Correspondingly, the first speaker device 20 is configured to receive radio frequency waves / signals of the preset communication frequency band. When the first speaker device 20 is within the radiation range of the radio frequency waves / signals, it can receive and play the first signal carried by the radio frequency waves / signals.

[0076] In some embodiments, the audio system further includes a vehicle communication device for connecting to the first speaker device 20 via a second communication method when the first speaker device 20 is not installed in the vehicle, and for sending a second signal to the first speaker device 20. The communication frequency band of the second communication method is different from the communication frequency band of the first communication method. Correspondingly, the first speaker device 20 is also used to mix the first signal and the second signal to obtain a first audio signal, and to play the first audio signal.

[0077] In this embodiment, the vehicle-mounted communication device is at least configured with a second communication mode function. When the first speaker device 20 is not installed in the vehicle, the vehicle-mounted communication device can connect to the first speaker device 20 via the second communication mode, thereby sending a second signal to the first speaker device 20. Here, the second signal generally refers to the audio signal sent by the vehicle-mounted communication device according to the communication frequency band of the second communication mode. That is, when any device or apparatus is connected to the vehicle-mounted communication device via the second communication mode, it can receive the second signal sent by the vehicle-mounted communication device according to the communication frequency band of the second communication mode.

[0078] It is understandable that the first speaker device 20 is not installed in the vehicle, meaning that the first speaker device 20 is not reinstalled in the vehicle. In actual use, in order to improve the audio playback effect of the speaker, the first speaker device 20 can be removed from the vehicle, that is, the first speaker device 20 can be used outside the vehicle.

[0079] As an example, in actual use, the vehicle terminal can play music accompaniment, or the vehicle terminal can receive music accompaniment sent by the mobile terminal, and use the music accompaniment as a second signal to send the music accompaniment to the first speaker device 20 through the vehicle communication device according to the communication frequency band of the second communication method.

[0080] For example, after the user removes the first speaker device 20 from the vehicle, they can manually power it on. At this time, the vehicle communication device can automatically establish a wireless connection with the first speaker device 20, meaning the vehicle communication device and the first speaker device 20 connect via a second communication method. Since the communication frequency band of the second communication method is different from that of the first communication method, the first and second communication methods can be parallel communication methods. That is, the first speaker device 20 can communicate with the receiving device via the first communication method while simultaneously communicating with the vehicle communication device via the second communication method. Furthermore, the first speaker device 20 can receive the first signal and the second signal, and by mixing the first and second signals, obtain the first audio signal, which can then be played. Here, the first audio signal generally refers to the audio content obtained after mixing the first and second signals.

[0081] In a specific implementation, the first speaker device 20 may be equipped with a mixing module and a power amplifier module. For example, the mixing module may be a mixing circuit built based on an audio DSP chip, and the power amplifier module may be a power amplifier circuit composed of speakers. The mixing circuit can be used to mix the first signal and the second signal, and then the first audio obtained from the mixing process can be played through the power amplifier circuit.

[0082] In some embodiments, the vehicle communication device can be configured to implement multiple communication methods, including connecting to the first speaker device 20 via a second communication method and connecting to the radio device via a first communication method.

[0083] In conjunction with the above example, as another example, the vehicle communication device can receive a first signal sent by the radio device, and mix the first signal with a second signal to obtain a second audio signal, which can then be played using the vehicle's audio system.

[0084] In practical implementation, the vehicle communication device can directly mix the first signal and the second signal to obtain the second audio. Alternatively, the vehicle communication device can send the first signal and the second signal to the vehicle terminal, where the vehicle terminal performs the mixing process to obtain the second audio. Or, the vehicle communication device can send the first signal and the second signal to the vehicle's audio system, where the vehicle's audio system performs the mixing process to obtain the second audio.

[0085] The above solution, where the first speaker device 20 is connected to the radio device via a first communication method, utilizes a vehicle-mounted communication device to connect to the first speaker device 20 via a second communication method, allowing the first speaker device 20 to communicate using both methods. In this way, the first speaker device 20 can receive both the first signal from the radio device and the second signal from the vehicle-mounted communication device, and then mix the first and second signals to play the resulting mixed audio. This provides a foundation for the audio system to receive the second signal provided by the vehicle and to mix the first and second signals.

[0086] As one embodiment, the receiving device is further configured to transmit a first signal to the vehicle-mounted communication device according to the communication frequency band of the first communication method. The vehicle-mounted communication device is further configured to mix the first signal with a second signal to obtain a second audio signal. The first speaker device 20 is further configured to receive and play the second audio signal when installed in a vehicle.

[0087] In this embodiment, when the vehicle communication device receives the first signal, it can mix it with the second signal and transmit the resulting second audio to the vehicle's audio system for playback. Since the first speaker device 20 can be used in conjunction with the vehicle's audio system when installed in the vehicle, the first speaker device 20 can receive and play the second audio when installed in the vehicle.

[0088] In practical implementation, the vehicle communication device can be equipped with a mixing module. For example, the mixing module can be a mixing circuit built based on an audio DSP chip. This mixing circuit can be used to mix the first signal and the second signal, and then the resulting second audio signal can be played through the vehicle's audio system. Here, since the first speaker device 20 is located in the vehicle, it can be considered as the speaker of the vehicle's audio system; that is, when the first speaker device 20 is installed in the vehicle, it can receive and play the second audio signal.

[0089] It is understandable that when the first speaker device 20 is installed in a vehicle, since it can be considered part of the vehicle's audio system, it can be controlled by the vehicle's control system or in-vehicle terminal. In this case, to prevent the first speaker device 20 from playing other audio content while playing the second audio, in practice, the connection between the first speaker device 20 and other non-in-vehicle devices can be disconnected when the first speaker device 20 is installed in the vehicle. For example, the first communication method connection between the first speaker device 20 and the radio can be disconnected.

[0090] The above solution mixes the first and second signals using an in-vehicle communication device, and when the first speaker device 20 is installed in the vehicle, sends the mixed second audio signal to the first speaker device 20 for playback. This allows the first speaker device 20 to be integrated into the vehicle's audio system when it is installed, thus improving the playback quality of the second audio signal.

[0091] As one possible implementation method, the communication frequency band of the first communication method includes at least one of the following: high frequency band HF, very high frequency band VHF, ultra-high frequency band UHF, and super high frequency band SHF.

[0092] Taking UHF (U-band) as an example, in practical implementation, a U-band transmitting module or U-band transmitting chip can be configured in the radio receiving device, and correspondingly, a U-band receiving module or U-band receiving chip can be configured in the first speaker device 20, thereby enabling the radio receiving device and the first speaker device 20 to be connected via a first communication method. Similarly, a U-band receiving module or U-band receiving chip can be configured in the vehicle communication device and the second speaker device respectively, thereby enabling the vehicle communication device and the second speaker device to be connected to the first speaker device 20 via the first communication method.

[0093] In all embodiments of this application, the second communication method is different from the first communication method, specifically meaning that the communication frequency band of the second communication method does not overlap with the communication frequency band of the first communication method.

[0094] As one possible implementation method, the second communication connection includes at least one of the following: Bluetooth communication connection, Zifeng communication connection, near field communication connection, and mobile hotspot communication connection.

[0095] Taking Bluetooth communication as an example of the second communication method, in practical implementation, Bluetooth communication modules, such as Bluetooth signal transceiver chips, can be configured in both the first speaker device 20 and the vehicle communication device, thereby enabling the first speaker device 20 and the vehicle communication device to connect via the second communication method. Similarly, a Bluetooth communication module can also be configured in the second speaker device, thereby enabling the second speaker device to be mounted on the first speaker device 2010 and to connect with the vehicle communication device via the second communication method.

[0096] This application also provides a vehicle including the aforementioned audio system.

[0097] It is understandable that in a vehicle with an audio system, the first speaker unit 20 is detachably installed in the vehicle, meaning that the first speaker unit 20 can be installed in the vehicle and used in conjunction with the vehicle's audio system, or it can be removed from the vehicle and used independently.

[0098] In some embodiments, the vehicle includes a rear compartment, and the first docking station 10 is disposed in the rear compartment. It is understood that placing the first docking station 10 in the rear compartment avoids impacting the interior passenger space.

[0099] In some embodiments, the vehicle includes a second docking station and a second speaker device, the second speaker device being detachably disposed at the second docking station. The second speaker device includes a fourth receiving unit and at least one second speaker. The fourth receiving unit is connected to the second speaker and is used to receive the target signal transmitted by the first transmitting unit.

[0100] Understandably, the second speaker unit is detachably installed at the second docking station, meaning that the second speaker unit can be used in conjunction with the vehicle's audio system or used independently.

[0101] The first speaker device 20 can emit a target signal through the first transmitting unit, so that the second speaker device can receive the target signal emitted by the first transmitting unit through the fourth receiving unit, thereby realizing the interconnection between the first speaker device 20 and the second speaker device. In this way, the signal at the first speaker device 20 can be transmitted to the second speaker device, so that the speaker system has the first speaker device 20 and the second speaker device. The first speaker device 20 and the second speaker device can work simultaneously, which is conducive to creating a more three-dimensional sound atmosphere.

[0102] Figure 3 A flowchart illustrating the implementation of a control method for an audio system according to an embodiment of this application is shown. It should be noted that the control method for an audio system provided in this embodiment is applied to... Figure 1 The audio system provided in the embodiment. For example... Figure 3 As shown, the control methods for the audio system specifically include:

[0103] Step 301: The first receiving unit 201 receives the first signal;

[0104] Step 302: The first receiving unit 201 outputs first data to the first processing module 202 according to the first signal;

[0105] Step 303: The first processing module 202 outputs the first audio signal to the first speaker 203 based on the first data;

[0106] Step 304: The first speaker 203 plays the first audio.

[0107] Understandably, the first receiving unit 201 receives the first signal, converts it into corresponding first data, and transmits it to the first processing module 202. The first processing module 202 receives the first data, processes it to obtain the first audio corresponding to the first signal, and sends the first audio to the first speaker 203. The first speaker 203 then plays the first audio, thus realizing the reception and playback of the audio signal.

[0108] In other words, by using the control method of this embodiment to control the operation of the audio system, the first speaker device 20 can work independently without relying on the first docking station 10. The first speaker device 20 can receive and play audio signals from the first docking station 10, and can also receive and play audio signals from other devices, thus reducing the limitations on the use of the first speaker device 20.

[0109] In some embodiments, the first speaker device 20 further includes a first transmitting unit, which is signal-connected to the first processing module 202;

[0110] The audio system further includes: a second speaker device; the second speaker device includes a fourth receiving unit and at least one second loudspeaker, the fourth receiving unit being connected to the second loudspeaker;

[0111] The control method for the audio system also includes:

[0112] The first processing module 202 outputs the first audio to the first sending unit based on the first data;

[0113] The first transmitting unit sends the first audio to the fourth receiving unit;

[0114] The fourth receiving unit outputs the first audio to the second speaker;

[0115] The second speaker plays the first audio.

[0116] Understandably, the first speaker device 20 can emit a first audio signal through the first transmitting unit, allowing the second speaker device to receive the first audio signal emitted by the first transmitting unit through the fourth receiving unit. The fourth receiving unit can then output the first audio signal to the second speaker, enabling the second speaker to play the first audio signal. This achieves the interconnection between the first speaker device 20 and the second speaker device, allowing both to play the first audio signal simultaneously, which is beneficial for the formation of stereo sound.

[0117] In some embodiments, the audio system includes at least two second speaker devices, each second speaker device including a second transmitting unit, the second transmitting unit being used to signal connect with the fourth receiving unit of another second speaker device;

[0118] The control method for the audio system also includes:

[0119] The second transmitting unit of one of the second speaker devices transmits the first audio to the fourth receiving unit of the other second speaker device;

[0120] The fourth receiving unit of another second speaker device outputs the first audio signal to the second speaker of another second speaker device;

[0121] The second speaker of another second speaker unit plays the first audio.

[0122] It is understood that each second speaker device includes a second transmitting unit and a fourth receiving unit, and each second speaker device can receive and transmit signals.

[0123] After receiving the first audio signal from the first transmitting unit, one of the second speaker devices transmits the first audio signal to the fourth receiving unit of another second speaker device, allowing the other second speaker device to also receive the first audio signal. The fourth receiving unit of the other second speaker device then outputs the first audio signal to its second speaker, causing the second speaker of the other second speaker device to play the first audio signal. This interconnects multiple speaker devices, allowing them to play the first audio signal simultaneously, thus improving the overall sound system experience.

[0124] For example, at least two second speaker devices include a third speaker device and at least two fourth speaker devices. The third speaker device can receive the first audio signal sent by the first speaker device 20, and then the third speaker device sends the first audio signal to the at least two fourth speaker devices, thereby realizing the interconnection between the first speaker device 20 and the at least two fourth speaker devices. The first speaker device 20, the third speaker device, and the at least two fourth speaker devices can play the first audio signal simultaneously, thereby enhancing the stereo sound effect of the audio system.
