[0002] Currently, there are various types of speakers on the market, and most support AI (Artificial Intelligence) dialogue and can control home appliances based on the user's voice. However, in practical applications, when the user is far from the speaker or there are obstacles such as walls between the user and the speaker, the speaker often cannot clearly pick up the user's voice. Furthermore, when the speaker is playing audio, the microphone is very close to the speaker, resulting in poor microphone pickup and preventing the speaker from clearly receiving the user's voice. Consequently, the speaker cannot accurately perform corresponding control operations based on audio control signals, affecting the user experience. Summary of the Invention

Attached Figure Description

[0029] To more clearly illustrate the technical solutions in the embodiments of the present invention, the drawings used in the prior art and embodiments will be briefly introduced below. Obviously, the drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0030] Figure 1 This invention provides a schematic diagram of the structure of a speaker.

[0031] Figure 2 This invention provides a schematic diagram of the structure of a speaker system;

[0032] Figure 3 This is a schematic diagram illustrating an application scenario of a speaker system provided by the present invention. Detailed Implementation

[0033] The core of this invention is to provide a speaker and speaker system that can accurately execute the user's operation even when the user is far away from the speaker or when the speaker cannot clearly receive the user's sound due to obstacles between the user and the speaker, thereby improving the user experience.

[0034] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Please refer to Figure 1 , Figure 1 This is a schematic diagram of the structure of a speaker provided by the present invention. The speaker includes a first processing module 1 and a speaker module 2. Each speaker module 2 includes a first UWB module and a first audio acquisition module.

[0036] The first audio acquisition module is used to acquire the first audio signal within its own area;

[0037] The first UWB module is used to acquire the second audio signal collected by the user's control device;

[0038] The first processing module 1 is used to compare the first audio signal with the second audio signal, and to perform corresponding operations based on the second audio signal when the first audio signal and the second audio signal are different.

[0039] Considering that in existing technologies, when the user is far from the speaker, there are obstacles between the user and the speaker, or the speaker is currently playing music, the speaker cannot clearly acquire the user's voice, resulting in the speaker being unable to accurately perform corresponding operations based on the user's voice, thus reducing the user experience. When situations arise where the user is far from the speaker, causing the speaker to be unable to clearly acquire the user's voice, the first audio signal acquired by the first audio acquisition module on the speaker differs significantly from the user's voice. Based on this principle, in this application, the first processing module 1 first compares the first audio signal acquired by the first audio acquisition module on the speaker with the second audio signal acquired by the control device carried by the user. When the first audio signal differs from the second audio signal, the corresponding operation is performed based on the second audio signal. Since the control device is carried by the user during use, the second audio signal acquired by the control device contains a clearer user voice, thereby ensuring the accuracy of the speaker in performing corresponding operations.

[0040] Please refer to Figure 1 , Figure 1 This is a schematic diagram of a speaker provided by the present invention. It should be noted that... Figure 1 Taking a speaker comprising three speaker modules 2 as an example, this embodiment does not specifically limit the exact number of speaker modules 2 included in the speaker. Specifically, the first audio acquisition module acquires the first audio signal within its own area. The specific range of this area is related to the performance of the first audio acquisition module, and parameters such as the gain of the first audio acquisition module can be adjusted according to actual conditions. The second audio signal in this application is specifically acquired through the first UWB module in the speaker. The first UWB module can wirelessly communicate with the control device carried by the user. When the first UWB module wirelessly communicates with the control device, the first UWB module automatically acquires the second audio signal acquired by the control device. Furthermore, compared to Bluetooth and WIFI, the first UWB module has stronger penetration and anti-interference capabilities, and also has the advantages of low power consumption, simple structure, and low cost, which can further improve the performance of the speaker.

[0041] Furthermore, when the first processing module 1 finds that the first audio signal and the second audio signal are the same, it indicates that the user is relatively close to the speaker. The first audio acquisition module in the speaker can clearly acquire the user's voice. Therefore, the first processing module 1 can perform the corresponding operation based on either the first audio signal or the second audio signal. This application does not make any special limitation on this.

[0042] In summary, this invention discloses a speaker, including a first processing module 1 and multiple speaker modules 2. Each speaker module 2 includes a first UWB module and a first audio acquisition module. The first audio acquisition module acquires a first audio signal from the area where the speaker is located. The first processing module 1 compares the first audio signal with a second audio signal acquired by a user-carried control device through the first UWB module. When the user is far from the speaker or when there are obstacles between the user and the speaker preventing the speaker from clearly receiving the user's sound (i.e., when the first audio signal and the second audio signal are different), the first processing module 1 directly performs corresponding operations based on the second audio signal, thereby obtaining clear user sound and accurately executing corresponding operations, improving the user experience.

[0043] Based on the above embodiments:

[0044] In a preferred embodiment, there are multiple speaker modules 2, and each speaker module 2 is evenly arranged around the first processing module 1. The control device includes a second processing module, a second UWB module, and a second audio acquisition module.

[0045] The first UWB module is specifically used to acquire the second audio signal sent by the second processing module through the second UWB module and acquired by the second audio acquisition module when the second UWB module is detected to be located in the preset recognition area;

[0046] The angle formed by the two boundaries of the preset recognition area is 360 degrees divided by the total number of speaker modules 2, and the preset recognition areas corresponding to each first UWB module do not overlap.

[0047] Considering that the UWB module can also perform positioning identification and establish communication connections within a designated area, this embodiment sets up multiple speaker modules 2 in the speaker, that is, multiple first UWB modules and corresponding first audio acquisition modules are set up in the speaker. When the control device carried by the user is located in different directions, the second audio signal is obtained through the first UWB module in the different speaker modules 2. Each speaker module 2 is evenly arranged around the first processing module 1 to achieve all-round coverage. The area in which the first UWB module in each speaker module 2 can perform positioning identification and establish communication connections is the preset identification area in this embodiment. The preset identification area is centered on the first processing module 1, and the angle formed by the two boundaries of the preset identification area is 360 degrees divided by the total number of speaker modules 2. Moreover, the preset identification areas corresponding to each first UWB module do not overlap with each other. Therefore, the minimum number of speaker modules 2 can be used to achieve full coverage of the area around the speaker. Please refer to Figure 1 , Figure 1 This is a schematic diagram of the structure of a speaker provided by the present invention. Figure 1 The speaker includes three speaker modules 2, each with a preset recognition area angle of 120 degrees. Please refer to... Figure 2 , Figure 2 This is a schematic diagram of a speaker system provided by the present invention. Figure 2 The star-shaped object in the user's hand is the control device. After the user carries the control device into the preset recognition area of ​​the first UWB module in the speaker module 2, the first UWB module can establish a communication connection with the second UWB module in the control device.

[0048] In this embodiment, the first UWB module can only establish a communication connection with the second UWB module in the control device when the control device carried by the user appears in the preset recognition area corresponding to the first UWB module itself, so as to obtain the second audio signal sent by the second processing module through the second UWB module and collected by the second audio acquisition module.

[0049] In a preferred embodiment, the first processing module 1 is further configured to perform corresponding operations based on the first audio signal acquired by the first audio acquisition module in the speaker module 2 corresponding to the preset identification area to which the control device belongs when the first audio signal is different from the second audio signal and the second audio signal does not meet the preset usability conditions.

[0050] Considering that the first processing module 1 determines that the first audio signal and the second audio signal are different, that is, when there may be situations such as the user being far away from the speaker or there being obstacles between the user and the speaker, the first processing module 1 should prioritize performing corresponding operations based on the second audio signal collected by the control device carried by the user. However, in order to ensure the accuracy of the speaker's corresponding operations, this embodiment also judges the availability of the second audio signal. When the second audio signal does not meet the preset availability conditions, that is, when it is determined that the second audio signal is unavailable, the corresponding operations should be performed based on the first audio signals collected by each of the first audio acquisition modules in the speaker. In addition, this application prioritizes performing corresponding operations based on the first audio signal collected by the first audio acquisition module in the speaker module 2 corresponding to the preset identification area to which the control device belongs, that is, performing corresponding operations based on the first audio signal collected by the first audio acquisition module closest to the user, which further ensures the accuracy of the speaker when performing corresponding operations.

[0051] Furthermore, this application does not impose any special limitations on the preset usable conditions, such as determining whether the frequency of the second audio signal is within a reasonable range or whether the fluctuation of the second audio signal is within a reasonable range.

[0052] In a preferred embodiment, the first processing module 1 is further configured to perform corresponding operations based on the first audio signal collected by the first audio acquisition module in the speaker module 2 corresponding to the preset identification area to which the control device belongs when the first audio signal collected by the first audio acquisition module in the available speaker module 2 does not meet the preset availability conditions.

[0053] Among them, the available speaker module 2 is any speaker module 2 other than the speaker module 2 corresponding to the preset recognition area to which the control device belongs.

[0054] In this embodiment, in order to further improve the accuracy of the speaker in performing corresponding operations based on the sound emitted by the user, when the first processing module 1 needs to perform corresponding operations based on the first audio signal collected by the first audio acquisition module in the speaker module 2 corresponding to the preset identification area to which the control device belongs, it first determines whether the first audio signal meets the preset availability conditions. If the first audio signal does not meet the preset availability conditions, it performs corresponding operations based on the first audio signal collected by the first audio acquisition module in other available speaker modules 2 in the speaker. Available speaker modules 2 refer to other speaker modules 2 in the speaker excluding the speaker module 2 corresponding to the preset identification area to which the control device belongs.

[0055] In summary, when the first processing module 1 determines that the first audio signal and the second audio signal are different, the priority of the audio signals used by the first processing module 1 when performing the corresponding operation in this application is as follows: the second audio signal acquired by the second audio acquisition module in the control device, the first audio signal acquired by the first audio acquisition module in the speaker module 2 corresponding to the preset identification area of ​​the control device, and the first audio signal acquired by the first audio acquisition module in the available speaker module 2. By setting the above priority, the accuracy of the first processing module 1 in performing the corresponding operation is guaranteed to the greatest extent, ensuring a good user experience.

[0056] In a preferred embodiment, the first UWB module is further configured to send a first presence signal to the first processing module 1 when the second UWB module is detected to be located within a preset identification area;

[0057] The first processing module 1 is also used to, after receiving the first presence signal, adjust the gain of the first UWB module in the main speaker module 2 to enhance the communication capability of the first UWB module in the main speaker module 2, and / or adjust the gain of the first audio acquisition module in the main speaker module 2 to enhance the sound pickup capability of the first audio acquisition module in the main speaker module 2.

[0058] Among them, the main speaker module 2 is the speaker module 2 to which the first UWB module that sends the first in-situ signal belongs.

[0059] In this embodiment, when the first UWB module detects that the second UWB module is located within a preset recognition area, it also sends a first presence signal to the first processing module 1. Upon receiving the first presence signal, the first processing module 1 adjusts the gain of the first UWB module, thereby enhancing its communication capability and enabling it to more accurately and completely acquire the second audio signal sent by the second UWB module. This lays the foundation for the first processing module 1 to perform corresponding operations based on the second audio signal. This application does not specifically limit how the gain of the first UWB module is adjusted, as long as the purpose of enhancing the communication capability of the first UWB module is achieved.

[0060] After receiving the first presence signal, the first processing module 1 adjusts the gain of the first audio acquisition module in the main speaker module 2 (i.e., the speaker module 2 to which the first UWB module that sent the first presence signal belongs). This enhances the sound pickup capability of the first audio acquisition module closest to the user, thereby improving the reliability of the first audio signal and further ensuring the accuracy of the first processing module 1 when performing corresponding operations. This application does not specifically limit how the gain of the first audio acquisition module is adjusted, as long as the purpose of enhancing the sound pickup capability of the first audio acquisition module is achieved.

[0061] In summary, this embodiment further improves the reliability of the speaker by specifically adjusting the gain of the first UWB module and the gain of the first audio acquisition module through the first processing module 1.

[0062] In a preferred embodiment, the first processing module 1 is also used to adjust the gain of the first audio acquisition module in other speaker modules 2 besides the main speaker module 2, so as to reduce the sound pickup capability of the first audio acquisition module in the other speaker modules 2.

[0063] In this embodiment, after the first processing module 1 receives the first presence signal, it adjusts the gain of the other speaker modules 2 besides the main speaker module 2 to reduce the pickup capability of the first audio acquisition module in the other speaker modules 2, thereby reducing interference from other directions and further improving the accuracy of the first processing module 1 when performing corresponding control. This application does not specifically limit how the gain of the other speaker modules 2 besides the main speaker module 2 is adjusted, as long as the purpose of reducing the pickup capability of the first audio acquisition module in the other speaker modules 2 is achieved.

[0064] In a preferred embodiment, the speaker module 2 also includes a first speaker;

[0065] The first UWB module is also used to send a second presence signal to the first processing module 1 when the second UWB module is detected to be located within a preset identification area;

[0066] The first processing module 1 is also used to increase the volume of the first speaker in the main speaker module 2 after receiving the second presence signal, wherein the main speaker module 2 is the speaker module 2 to which the first UWB module that sent the second adjustment signal belongs.

[0067] Considering that users sometimes play music through speakers, and that there are multiple speaker modules 2 in this application, the speakers in this application can adjust the sound effects according to the user's actual position, ensuring that the user can always experience the best listening experience. Please refer to... Figure 3 , Figure 3 This is a schematic diagram illustrating an application scenario of a speaker system provided by the present invention. The speaker can establish a communication connection with the user's control device via the first UWB module before the user enters their home.

[0068] Specifically, the speaker contains multiple speaker modules 2, each including a first speaker. Since the first UWB module in each speaker module 2 has a positioning and recognition function, when the first UWB module detects that a second UWB module is located within a preset recognition area, it sends a second presence signal to the first processing module 1. In this application, the speaker module 2 to which the first UWB module sending the second adjustment signal belongs is designated as the main speaker module 2. After receiving the second presence signal, the first processing module 1 amplifies the volume of the first speaker in the main speaker module 2, thereby providing the user with a better listening experience and improving the user experience of the speaker.

[0069] In a preferred embodiment, the speaker module 2 further includes a first speaker, and the control device further includes a second speaker;

[0070] The first UWB module is also used to generate a third presence signal when the second UWB module is detected to be located within a preset recognition area;

[0071] The first processing module 1 is used to send an audio playback control signal to the second UWB module through the first UWB module after receiving the third presence signal, so that the second processing module can control the second speaker to play the same audio as the first speaker after receiving the audio playback control signal sent by the second UWB module.

[0072] Considering that users may temporarily move away from the speaker while playing music, making it difficult to hear the music clearly, and leveraging the strong penetration and long-distance wireless communication capabilities of the first and second UWB modules, the first processing module 1 controls the second speaker in the user-carried control device to synchronously play the same audio as the first speaker in the speaker. Specifically, when the first UWB module detects that the second UWB module is within a preset identification area, it generates a third presence signal. Upon receiving the third presence signal, the first processing module 1 sends an audio playback control signal to the second UWB module through the first UWB module. Upon receiving the audio playback control signal, the user-carried control device plays audio through the second speaker. Since both the first speaker in the speaker and the second speaker in the control device play music based on the same audio playback control signal, the second speaker can play the same audio as the first speaker. This ensures that even when the user is far from the speaker or there is an obstruction between them, the user can still hear the audio played by the speaker, guaranteeing that the user can always hear the audio clearly.

[0073] Please refer to Figure 2 , Figure 2 This application provides a schematic diagram of a speaker system, which includes the aforementioned speaker and a control device for acquiring a second audio signal within the user's area.

[0074] This application discloses a speaker system, which includes a speaker and a control device. The speaker includes a first processing module 1 and multiple speaker modules 2. Each speaker module 2 includes a first UWB module and a first audio acquisition module. The first audio acquisition module acquires a first audio signal from the area where the speaker is located. The first processing module 1 compares the first audio signal with a second audio signal acquired by the user-carried control device through the first UWB module. When the user is far from the speaker or when there are obstacles between the user and the speaker that prevent the speaker from clearly receiving the user's sound (i.e., the first audio signal and the second audio signal are different), the first processing module 1 directly performs corresponding operations based on the second audio signal to obtain clear user sound and accurately execute corresponding operations, thereby improving the user experience.

[0075] also, Figure 2 Taking a speaker that includes three speaker modules 2 as an example, this embodiment does not specifically limit the number of speaker modules 2 included in the speaker.

[0079] The second UWB module is used to receive audio playback control signals sent by the speaker through the first UWB module, and to send the second audio signal acquired by the second processing module through the second audio acquisition module.

[0080] The second processing module is used to control the second speaker to play audio based on the audio playback control signal.

[0081] In this embodiment, the control device includes a second processing module, a second UWB module, a second audio acquisition module, and a second speaker, capable of acquiring the user's voice, enabling wireless communication with the speaker, and playing audio. Furthermore, the control device may also include a charging module. Because the control device contains relatively few components, its size is approximately the size of a button battery, allowing it to be made into items such as keychains, wristbands, necklaces, or earrings that are easy for users to carry.
