[0002] In the field of audio equipment, a sound box is a core terminal component of a sound system, which undertakes the key task of converting electrical signals into sound energy. From the perspective of function implementation, the sound box can receive audio signals, amplify the audio signals with the power amplifier provided in the main box or the bass cannon box, convert the processed signals into sound and radiate to the space, and finally realize the restoration and amplification of sound, so that users can directly listen to it.

[0003] However, in the existing left and right channel sound boxes, the audio input interface and the audio output interface are usually designed separately. For example, the left channel sound box is configured with an audio input interface to connect the sound source, and the right channel sound box needs to be connected to the audio input interface of the left channel sound box through the audio output interface. The above-mentioned design requires users to strictly distinguish the types of audio interfaces, but in actual operation, due to the similar appearance of the audio input interface and the audio output interface and the lack of intuitive identification, users are prone to connection errors. According to market research data, more than 65% of users have experienced interface confusion when connecting stereo sound boxes for the first time.

[0004] The above-mentioned deficiencies need to be solved. SUMMARY

[0027] Please refer to Figures 1 to 3The embodiment of the present application provides a sound box capable of automatically switching input and output properties of an interface and a control method thereof, comprising a main control chip 1, a main and auxiliary box connection port 2, a position sensor 3, an audio input interface 4, a power module 5 and a power amplifier module 6, wherein the main control chip 1 is connected with the main and auxiliary box connection port 2, the position sensor 3, the audio input interface 4, the power module 5 and the power amplifier module 6 respectively. The main and auxiliary box connection port 2 is a digital audio input and output interface, such as an SPDIF interface, and has two modes of input and output, which can be flexibly switched according to the instruction of the main control chip 1. The position sensor 3 is used for detecting the placement direction information of the sound box in real time or at a fixed time, thereby providing a basis for the sound box to determine the master or slave role. The audio input interface 4 is used for receiving the audio signal of an external audio source and providing the sound source for the sound box. After the audio input interface 4 is connected with the main control chip 1, the received signal can be accurately transmitted to the power amplifier module 6 under the control of the main control chip 1, thereby ensuring the stable input of the audio signal. The power module 5 is used for providing stable power supply for each component of the sound box, thereby ensuring that the main control chip 1, the position sensor 3, the power amplifier module 6 and the like can normally work and is a basic guarantee component for the normal operation of the sound box. The main control chip 1 serves as the brain of the sound box and is used for determining whether the sound box is a master or a slave according to the placement direction information detected by the position sensor 3 and switching the input and output properties of the main and auxiliary box connection port 2 according to the determination result. For example, when the main control chip 1 determines that the sound box is a master according to the placement direction information detected by the position sensor 3 (for example, the sound box is vertically placed in a forward direction), the main and auxiliary box connection port 2 is configured to be in an output working mode through register configuration or pin level control, and at this time, the main and auxiliary box connection port 2 is an audio output interface. When the main control chip 1 determines that the sound box is a slave according to the placement direction information detected by the position sensor 3 (for example, the sound box is vertically placed in a reverse direction), the main and auxiliary box connection port 2 is configured to be in an input working mode through register configuration or pin level control, and at this time, the main and auxiliary box connection port 2 is an audio input interface 4.

[0028] In the embodiment, only one main and auxiliary box connection port 2 is arranged, and the main control chip 1 can automatically switch the input and output properties of the main and auxiliary box connection port 2 according to the placement direction information detected by the position sensor 3, so that the user does not need to distinguish the input and output properties of the main and auxiliary box connection port 2, the connection error caused by the confusion of the interface is avoided, the connection between the main and auxiliary sound boxes is more convenient, and the user who uses the sound box for the first time can also easily complete the connection.

[0029] In one embodiment, the main control chip 1 is a Bluetooth master control chip. The Bluetooth master control chip enables the sound box to have the function of Bluetooth wireless connection, so that the user does not need to use the traditional audio cable to connect the audio source device, such as a mobile phone, a tablet computer and the like, thereby greatly simplifying the connection process of the device, the user only needs to turn on the Bluetooth function of the device and perform simple pairing, so that the audio transmission channel can be quickly established, and the convenience and flexibility of use are improved.

[0030] In one embodiment, the position sensor 3 is a gyroscope. As a sensor capable of accurately measuring the angular velocity and rotation angle of an object, the gyroscope can be applied to the sound box as the position sensor 3 to accurately detect the placement direction information of the sound box, including the tilt angle and the rotation direction, thereby providing a reliable basis for the main control chip 1 to accurately determine whether the sound box is a master or a slave, and ensuring that the automatic switching of the input and output properties of the audio interface is more accurate and reliable. At the same time, the gyroscope has fast response characteristics and can sense the change in the direction of the sound box in real time.

[0031] In one embodiment, the audio input interface 4 is an HDMI ARC input interface. The HDMI ARC input interface supports the transmission of high-definition audio signals and can transmit high-quality multi-channel audio formats including Dolby Digital, DTS, etc. Compared with traditional audio interfaces, the HDMI ARC input interface can provide richer and more realistic audio experience, allowing users to enjoy cinema-level high-quality sound effects.

[0032] Please refer to Figure 2 In one embodiment, the power module 5 includes a power conversion circuit 501 and an adapter power supply 502, and the power conversion circuit 501 is connected with the adapter power supply 502 and the main control chip 1 respectively. The power conversion circuit 501 is used to convert and stabilize the voltage input by the adapter power supply 502, to ensure that the voltage output to the main control chip 1 and other modules is stable within a suitable range. The adapter power supply 502 is used to adapt to different external power supply specifications, such as common household voltages of 110V-240V, or different specifications of DC power input, so that the sound box can be used in various power supply environments, whether it is at home, in the office, or outdoors (with a suitable mobile power adapter), without worrying about power compatibility problems, greatly improving the versatility and applicability of the sound box.

[0033] Please refer to Figure 2 In one embodiment, the power amplifier module 6 includes a power amplifier chip 601, a full-frequency speaker 602, and a bass speaker 603, and the power amplifier chip 601 is connected with the full-frequency speaker 602, the bass speaker 603, and the main control chip 1 respectively. The full-frequency speaker 602 can cover a wide frequency range and restore the details of human voice, medium-high frequency instruments, etc., while the bass speaker 603 focuses on the restoration of low-frequency sounds such as drum sounds and basses. By driving the full-frequency speaker 602 and the bass speaker 603 simultaneously through the power amplifier chip 601, the sound box can output rich high, medium, and low frequency sounds at the same time, making the sound levels more distinct and providing users with a more full and stereoscopic auditory experience, as if they were at a music venue.

[0034] Please refer to Figure 2In an embodiment, the sound box further comprises a light module 7 connected with the master control chip 1. The light module 7 is a fantasy LED strip, which can emit lights of multiple colors and can realize dynamic changes of parameters such as light color, brightness, and flickering frequency. When the sound box plays music, the fantasy LED strip can change light effects according to the rhythm and melody of the music, creating a visual atmosphere matching the music, so that the user can enjoy the music while also enjoying the splendid visual enjoyment, enhancing the overall entertainment and interest of the sound box. The master control chip 1 can also switch the light mode of the fantasy LED strip according to the placement direction information detected by the position sensor 3, realizing the linkage of the sound box function and the light effect. For example, when the sound box is placed in a first vertical placement direction, the fantasy LED strip displays a specific light mode; when the sound box is placed in a second vertical placement direction, it is switched to another light mode. This interconnection design not only increases the technological and interesting nature of the sound box, but also allows the user to intuitively understand the working state of the sound box through the light mode, improving the user experience.

[0035] Please refer to Figure 2 In an embodiment, the sound box further comprises a key module 8 connected with the master control chip 1. The key module 8 provides a direct and convenient local operation method for the user, so that the user does not need to rely on a mobile phone APP or other remote control devices, but only needs to press the keys on the sound box directly to quickly realize various functions such as power on / off, volume adjustment, song switching, and mode selection (such as Bluetooth mode, audio input mode, etc.).

[0036] Preferably, the key module 8 is a touch key. Since the touch key has no physical travel of traditional mechanical keys, the user only needs to lightly touch the key area to complete the operation, making the operation process more relaxed and fast. Moreover, the surface of the touch key can be designed to be more flat and simple, with higher integration with the overall appearance of the sound box, making the sound box more beautiful in appearance.

[0037] Please refer to Figure 2 In an embodiment, the sound box further comprises an optical fiber input interface 9 connected with the master control chip 1. The optical fiber input interface 9 is used to connect to the Internet through a network cable, so that the sound box can access rich online resources and services. For example, the user can directly listen to the vast music library of various online music platforms on the sound box without the need for transshipment through other devices; can also listen to network radio, audio books, etc., greatly expanding the functions and use scenarios of the sound box. In addition, the sound box can also be integrated with a smart home system to realize linkage control with other smart devices through the network interface, such as automatically playing specific music according to the time, cooperating with other smart devices to create a home atmosphere, etc.

[0038] Please refer toFigure 2 In one embodiment, the sound box further comprises a USB sound card interface 10 connected with the master control chip 1. The USB sound card interface provides the sound box with the possibility of connecting various external audio devices. The sound box with the USB sound card interface is no longer just a simple audio playback device, but a comprehensive audio device integrating audio playback, recording, processing and other functions. Users can connect audio input devices such as microphones and musical instruments to the sound box through the USB sound card interface to realize the recording function of audio. For example, music lovers can use a microphone to connect the sound box to record their own singing or playing works; they can also connect musical instruments such as electronic keyboards and guitars to the sound box for music creation and practice. At the same time, the sound box can also connect external storage devices (such as USB flash drives and mobile hard drives) through the USB sound card interface to directly play audio files stored therein, making it convenient for users to manage and play their own music collections.

[0039] Please refer to Figure 2 In one embodiment, the sound box further comprises a headphone microphone input / output interface 11 connected with the master control chip 1. The headphone microphone input / output interface 11 allows users to connect headphones or microphones, enabling users to enjoy music or sing through the sound box without disturbing others. The headphone microphone input / output interface 11 adopts a standard 3.5mm interface, which is very common in the market and has strong compatibility.

[0040] Please refer to Figure 3 In one embodiment, the present application provides a sound box control method applied to the sound box with the automatic switching interface input / output attribute described in the above embodiment, comprising the following steps: Step S1, after the sound box is powered on, the master control chip performs initialization operation, including initialization configuration of the position sensor, each interface, power amplifier, light and other modules; this step can ensure that each component is in a ready state, avoiding signal transmission errors caused by un-initialized modules; Step S2, the master control chip acquires the placement direction information detected by the position sensor in real time, and cyclically judges whether the sound box meets the slave mode and the master mode; this step can realize dynamic monitoring of the sound box state, ensuring that the system can quickly perceive after the placement direction of the sound box changes; Step S3, if the slave mode is detected, the sound box is in the slave mode, and the master control chip configures the master-slave box connection port as an input working mode according to the configuration parameters saved in the register; this step realizes the passive receiving role positioning of the slave, without the need for users to manually plug in or set the interface attribute; Step S4, if it is detected that the host placement mode is met, the sound box is in the host mode, the master control chip controls the light module to enter the light mode, and the master control chip configures the master-slave sound box connection port to the output working mode according to the configuration parameters saved in the register; this step realizes the active transmission role positioning of the host, and the linkage light module enhances the user experience, without the user manually plugging or setting the interface attribute, and the master-slave sound box can complete the bidirectional communication through a single interface, which simplifies the physical connection between the master-slave sound boxes.

[0041] The above-mentioned sound box control method, based on the sound box hardware structure with automatic switching of the interface input-output attribute, realizes the full-automatic switching of the master-slave sound box roles and the interface attribute through the logical flow of initialization, direction detection, mode judgment, and interface switching, without the user distinguishing the input-output attribute of the master-slave sound box interface, and the position sensor automatically identifies the placement direction and matches the mode, which reduces the connection difficulty, is friendly to novice users, and avoids connection errors caused by interface confusion.

[0042] Please refer to Figure 4 In one embodiment, the placement direction information includes a first placement direction, a second placement direction, and a third placement direction. In step S2, after the master control chip obtains the placement direction information in real time, it cyclically judges whether the sound box meets the slave placement mode, the host placement mode one, and the host placement mode two, to support the slave mode, the host mode one, the host mode two, and other multi-scene adaptation, which expands the use scenarios of the sound box. Among them, the first placement direction corresponds to the slave placement mode, the second placement direction corresponds to the host placement mode one, and the third placement direction corresponds to the host placement mode two. Of course, in other embodiments, the placement direction information can also include a fourth placement direction, a fifth placement direction, or more placement directions corresponding to each host placement mode, and the present application does not limit this, and those skilled in the art can set it according to their own needs.

[0043] Further, step S4 includes the following sub-steps: Step S401, if it is detected that the host placement mode one is met, the sound box is in the host mode one, the master control chip controls the light module to enter the light mode one, and the master control chip configures the master-slave sound box connection port to the output working mode; Step S402, if it is detected that the host placement mode two is met, the sound box is in the host mode two, the master control chip controls the light module to enter the light mode two, and the master control chip configures the master-slave sound box connection port to the output working mode.

[0044] The steps S401-S402 realize fine control of the same role and different functions by distinguishing between the host mode one and the host mode two, satisfy different light modes of the user in different scenes, and the differentiation of the light modes enhances the interaction (such as rhythm of strong music corresponds to fast flashing light, and slow music corresponds to gradual light) of the user and the device, and improves the entertainment and technology of the product.

[0045] Further, although the operations of the inventive method are described in a particular, sequential order, this is not meant to be a limitation, and any number of the operations can be performed in any order, and / or the operations can be combined into fewer operations, and / or the operations can be divided into more operations. Additionally or alternatively, certain steps can be omitted, and / or certain steps can be performed more than once.

[0046] It is to be understood that the above description is intended to be illustrative, and not restrictive. Many other implementations will be apparent to those of ordinary skill in the art upon reviewing the above description. The scope of the application should be determined, not with reference to the above description, but should instead be determined with reference to the appended claims, along with the full scope of equivalents to which such claims are entitled. The disclosures of each patent, patent application, and publication cited above are hereby incorporated herein by reference, each in its entirety.

[0047] The above has been described by way of example with reference to the drawings. Obviously, the implementation of the present application is not limited to the above-described manner, and various improvements can be made to the method concept and technical solutions of the present application, or the present application can be directly applied to other occasions without improvement, and all of these are within the protection scope of the present application.
