[0045] In order to more clearly illustrate the technical solutions of the embodiments of the present application or the prior art, the specific embodiments of the present application will be described below with reference to the drawings. Obviously, the drawings in the following description only represent some of the embodiments of the present application, and for those skilled in the art, other drawings can be obtained from these drawings without creative labor, and other embodiments can also be obtained.

[0046] In order to make the drawing simple, only the parts related to the present application are shown in each drawing, which do not represent the actual structure of the product. In addition, in order to make the drawing simple and easy to understand, in some drawings, only one of the components with the same structure or function is shown schematically, or only one of them is marked. In this paper, "one" not only means "only one", but also means "more than one".

[0047] At present, there are various types of audio products on the market, covering traditional wired speakers, wired earphones, modern wireless speakers, wireless earphones and other forms. Although technology is constantly improving, speakers and earphones are still mainly regarded as independent entities operating in the field of audio playback. Traditional speakers and earphones each play specific audio content, and fail to integrate in a complete environment to achieve a better sound experience. In addition, existing speaker systems usually only play audio in one fixed direction, lacking the ability to dynamically adjust the direction of audio propagation according to the user's position or angle. This fixed audio propagation method often leads to insufficient audio propagation accuracy, thereby reducing the quality of user experience.

[0048] The application integrates advanced positioning technologies such as ultra-wideband (UWB) to achieve high-precision detection of user position and orientation. This technology not only improves the accuracy of audio propagation, but also dynamically adjusts the audio output direction according to the user's movement, providing a more personalized and immersive audio experience. By integrating headphones and sound systems into a complete environment, not only can audio playback be shared between the two, but also directional audio playback can be achieved, further improving overall audio quality and user satisfaction. In addition, in this application scenario, headphones and sound systems can play different audio levels simultaneously, such as vocals and main melodies played by headphones, while background effects and environmental sounds played by sound. In this way, users can enjoy music or other audio experiences while showcasing the depth and richness of audio between different devices, achieving an unprecedented audio experience.

[0049] In one embodiment, the application provides a hybrid audio system, as shown in Figure 1 The hybrid audio system includes headphones 10, sound 30, and positioning module 40. The sound 30 determines the position information of the headphones 10 through the positioning module 40, and then determines the head position information and orientation information of the headphones wearer, and dynamically adjusts the audio propagation direction according to the head position information and orientation information of the headphones wearer, so that the first audio played by the headphones 10 and the second audio played by the sound 30 form a hybrid audio.

[0050] Specifically, in a system integrated with sound 30 and headphones 10, the sound 30 periodically detects positioning signals or positioning parameters through the positioning module 40, and processes the detected positioning signals or positioning parameters through an algorithm to calculate the head position information and orientation information of the headphones wearer. According to the head position information and orientation information, the sound 30 adjusts the output power and phase of different speakers to achieve directional audio propagation.

[0051] By integrating headphones 10 and sound 30 into a complete system through the positioning module, the sound 30 can dynamically adjust the propagation direction of the audio based on the head position information and orientation information of the headphones wearer, ensuring that users can obtain the best auditory experience regardless of their position or orientation, and improving the sense of space and immersion.

[0052] In another embodiment of the application, on the basis of any one of the above embodiments, the hybrid audio system can also integrate headphones 10 and sound 30 in the same environment using other positioning modules, such as Bluetooth positioning, infrared positioning, Wi-Fi positioning, inertial measurement unit, and sound wave positioning, which are not limited by the application.

[0053] In one embodiment, as shown in Figure 2As shown, the speaker 30 includes a first UWB transmitting module 31, and the earphone 10 includes a first UWB receiving module 11. The speaker 30 periodically transmits UWB signals through the first UWB transmitting module 31, and the earphone 10 receives UWB signals through the first UWB receiving module 11. Based on the timestamp and phase difference of each received UWB signal, the earphone 10 calculates the head position and orientation information of the earphone wearer, and sends the head position and orientation information of the earphone wearer to the speaker 30.

[0054] In this application, both the headphones 10 and the speaker 30 integrate UWB positioning modules. Specifically, the speaker 30, as the UWB signal transmitter, periodically sends UWB pulse signals through its built-in first UWB transmitting module 31. These UWB pulse signals are high-frequency pulses with extremely high time resolution, and they include, but are not limited to, timestamp information for the receiving end to perform time synchronization and calculations. Simultaneously, the headphones 10, as the receiving end, receives the UWB pulse signals from the speaker 30 through its built-in first UWB receiving module 11. After receiving the UWB pulse signals sent by the speaker 30, the first UWB receiving module 11 calculates the head position and orientation information of the headphone wearer by measuring the arrival time and angle of the signal. Meanwhile, the processor inside the headphones 10 further processes the head position and orientation information, including noise removal and data smoothing, and sends the processed data to the speaker 30. The speaker 30 adjusts the direction of its speaker array based on the processed data to achieve directional audio playback.

[0055] By integrating a UWB module into the headphones 10 and the speaker 30, and using the headphones 10 as the transmitter and the speaker 30 as the receiver, the speaker 30 can directly calculate the head position and orientation information of the headphone wearer in real time based on the received signal, thereby improving the positioning accuracy of the audio.

[0056] In one embodiment, such as Figure 3 As shown, the earphone 10 includes a second UWB transmitting module 12, and the speaker 30 includes a second UWB receiving module 32. The earphone 10 periodically transmits UWB signals through the second UWB transmitting module 12, and the speaker 30 receives UWB signals through the second UWB receiving module 32. Based on the timestamp and phase difference of each received UWB signal, the speaker calculates the head position and orientation information of the earphone wearer.

[0057] In the present application, the earphone 10 and the sound box 30 are integrated with the UWB positioning module. Specifically, the earphone 10 serves as the sending end of the UWB signal, and regularly sends UWB pulse signals through the built-in second UWB sending module 12. These UWB pulse signals are high-frequency pulses with extremely high time resolution, and these UWB pulse signals include but are not limited to timestamp information, so that the receiving end can perform time synchronization and calculation. At this time, the sound box 30 serves as the receiving end, and receives the UWB pulse signals from the earphone 10 through the built-in second UWB receiving module 32. After the second UWB receiving module 32 receives the UWB pulse signals sent by the earphone 10, the second UWB receiving module 32 measures the arrival time and the arrival angle of the signals, and calculates the head position information and the orientation information of the earphone wearer. At the same time, the processor inside the sound box 30 further processes the head position information and the orientation information, including removing noise and smoothing data, etc. According to the processed data, the processor adjusts the direction of the loudspeaker array to realize directional audio playback.

[0058] By integrating the UWB module in the earphone 10 and the sound box 30, and taking the sound box 30 as the sending end and the earphone 10 as the receiving end, the sound box 30 can obtain the position information and the orientation information provided by the earphone 10, thereby improving the response speed of the system and the accuracy of the position data.

[0059] In one embodiment, as shown in Figure 4 The mixed audio system is in communication connection with the smart device 20.

First, ensure that the sound box and the earphone are in the powered-on state and enter the Bluetooth pairing mode, second, the smart device 20 pairs with the sound box and the earphone through Bluetooth, and when the smart device 20 successfully pairs with the sound box and the earphone, the user sends an audio signal to the mixed audio system through the smart device 20. Specifically, the smart device 20 includes an audio processing module 21, which is used to divide the audio signal to be played into a first audio signal and a second audio signal, and send them to the earphone and the sound box, respectively.

[0060] By communicating with the smart device 20 and sending the audio signal to the earphone and the sound box, the mixed audio system realizes the function of synchronously outputting audio by multiple devices, and enhances the user experience.

[0061] In another embodiment of the present application, on the basis of any one of the above embodiments, the mixed audio system can also realize communication connection with the smart device 20 using other communication technologies, such as Wi-Fi, etc., which is not limited in the present application.

[0063] Specifically, in the embodiment, the first communication module 13 and the second communication module 33 are Bluetooth communication modules, the earphone and the sound box are respectively integrated with the Bluetooth communication modules, and are connected with the smart device 20 through the Bluetooth communication modules, and then the audio signals sent by the smart device 20 are received through the Bluetooth communication modules to play the corresponding audio content according to the audio signals.

[0064] Through the communication connection between the earphone and the smart device 20 and the connection between the sound box and the smart device 20, the smart device 20 can directly control and independently send the audio signals to the earphone and the sound box, which improves the selectivity and independence of the audio output. In addition, the user can flexibly choose to use the earphone or the sound box, or use both of them.
