Description

Technical Field

[0001] This utility model relates to the field of audio data processing technology, specifically to an infinitely expandable OTG digital live streaming and recording dock. Background Technology

[0002] As people's lives become increasingly richer, live streaming of outdoor music performances is gradually emerging. However, outdoor live streaming typically involves transmitting audio data from an audio output device to a smart device for audio effect conversion. Moreover, this audio data transmission method can only transmit audio data to one smart device, making it impossible to achieve the effect of multiple smart devices receiving audio data simultaneously.

[0003] Existing devices capable of expanding audio data include docking stations, but docking stations with OTG interfaces only support single-device connections and cannot meet the needs of multi-platform live streaming. When distributing signals from multiple devices, there are issues such as audio delay asynchrony and signal attenuation. They also lack integrated power supply modules, leading to insufficient power supply and disconnection when multiple devices are connected. Headphone monitoring requires additional adapters, increasing system complexity. Utility Model Content

[0004] To address the technical deficiencies in the background technology, this utility model proposes an infinitely expandable OTG digital live streaming and recording docking station, which solves the aforementioned technical problems and meets practical needs. The specific technical solution is as follows:

[0005] This utility model discloses an infinitely expandable OTG digital live streaming and recording dock. The dock includes a main body, in which a motherboard integrates an audio input port and a power supply interface. The audio input port is used to connect to a first audio output port on an audio input device to receive audio data. The motherboard integrates several second audio output ports for connecting to audio output devices. Each second audio output port is connected to a control chip integrated on the motherboard. The control chip is connected to the audio input port. The second audio output ports transmit audio data to the audio output device via OTG input. The second audio output ports are connected to the power supply interface through the motherboard.

[0006] As a further embodiment of this utility model, the audio output device is a smart terminal device.

[0007] As a further embodiment of the present invention, a plurality of the second audio output ports include at least one of a USB Type-C interface and a USB-A interface.

[0008] As a further embodiment of this utility model, the motherboard also integrates a listening interface.

[0009] As a further embodiment of this utility model, the audio output device has the same structure as the main body of the expansion dock, and the audio input port of the audio output device is connected to the second audio output port of the main body of the expansion dock for audio data transmission, thereby forming an audio data transmission link outside the main body of the expansion dock.

[0010] As a further embodiment of this utility model, the audio data transmission link consists of at least two or more audio output devices, which are sequentially connected through the second audio output port of one of the audio output devices to the audio input port of another audio output device.

[0011] As a further embodiment of this utility model, the main board of the expansion dock is provided with a power supply chip that is connected to the power supply interface and controls the charging power of the second audio output port.

[0012] The beneficial effects of this utility model are as follows: The expansion dock transmits audio data via OTG input to the audio output device connected to the second audio output port through the audio input port. Each control chip independently controls one channel of the second audio output port to output audio data, thereby achieving low-latency multi-channel synchronous distribution of audio data. Moreover, it connects to an external power supply through a power interface, which directly supplies power to the second audio output port. While outputting audio data to the audio output device through the second audio output port, it can also charge the audio output device connected to the second audio output port, solving the problem of unstable power supply when the external expansion dock is in use. This avoids the power supply problem of the expansion dock affecting the audio output effect when multiple audio output devices are used for simultaneous live streaming of singing and playing, and solves the problems of device compatibility, signal stability and user experience in multi-platform live streaming scenarios.

[0022] This utility model discloses an infinitely expandable OTG digital live streaming and recording docking station, such as... Figure 1 and Figure 2 As shown, the docking station includes a main body 1. The motherboard 17 in the main body 1 integrates an audio input port 11 and a power supply interface 12. The audio input port 11 is used to connect to the first audio output port 21 on the audio input device 2 to receive audio data. The motherboard 17 integrates several second audio output ports 13 for connecting to the audio output device 3. The second audio output ports 13 are connected to a control chip 14 integrated on the motherboard 17. The control chip 14 is connected to the audio input port 11. The second audio output ports 13 transmit audio data to the audio output device 3 via OTG input. The second audio output ports 13 are connected to the power supply interface 12 through the motherboard 17.

[0023] It should be noted that: when performing a live performance, firstly, the audio data output port (not shown in the figure) of the electronic instrument 5 used for the performance is connected to the audio data receiving port (not shown in the figure) on the audio input device 2 via a wired or wireless connection, thereby realizing the audio data transmission from the electronic instrument 5 to the audio input device 2; then, the audio input port 11 on the main body 1 of the expansion dock is connected to the first audio output port 21 on the audio input device 2 via a data cable, and the audio input device 2 transmits audio data to the audio input port 11 through the first audio output port 21, thereby transmitting the audio data to the main body 1 of the expansion dock; then, at least one audio output device 3 that needs to be used is connected to each of the second audio output ports 13 on the main body 1 of the expansion dock via a data cable, and the control chip 14 individually controls the data transmission path formed by one second audio output port 13 and the data interface (not shown in the figure) on the audio output device 3 to transmit audio data, and transmits the audio data to the audio output device 3 via OTG input, thereby realizing the multi-channel synchronous output of audio data to the audio output device 3.

[0024] In addition, by connecting to an external power source through the power supply interface 12, the main body 1 of the docking station can be powered directly to the second audio output port with a stable voltage input from the external power source. This enables the second audio output port to output audio data to the audio output device more stably, while also charging the audio output device connected to the second audio output port.

[0025] The aforementioned expansion dock transmits audio data via OTG input to the audio output device 3 connected to the second audio output port 13 through the audio input port 11. Each control chip 14 independently controls one channel of the second audio output port 13 to output audio data, thereby achieving low-latency multi-channel synchronous distribution of audio data. Moreover, an external power supply can be connected through the power supply interface 12, thus solving the problem of unstable power supply to the external expansion dock body 1 during use. This avoids the power supply problem of the expansion dock affecting the audio output effect when multiple audio output devices 3 are used for simultaneous live streaming of singing and playing, and solves the problems of device compatibility, signal stability and user experience in multi-platform live streaming scenarios.

[0026] It needs to be further explained that, such as Figures 2-4 As shown, the audio output device 3 is a smart terminal device.

[0027] When the audio output device 3 is a smart terminal device, the smart terminal device can receive audio data through its data interface connected to the second audio output port 13, and then use the audio data in the software of the smart terminal device, such as recording and live audio effect conversion. Moreover, when performing live singing and playing, multiple smart terminal devices connected to the second audio output ports 13 can simultaneously perform digital audio conversion for multiple live streaming platforms, making multi-platform live singing and playing operations more convenient. In addition, the power supply interface 12 can transmit power to the smart terminal device connected to the second audio output port 13 through an external power supply, thereby realizing the function of charging the smart terminal device while it is performing audio data conversion operations.

[0028] It should be further noted that several of the second audio output ports 13 include at least one of a USB Type-C interface and a USB-A interface.

[0029] The second audio output port 13 uses different types of USB interfaces, which can be used to connect with audio output devices 3 of different data interface types. This allows the docking station to meet the audio data transmission needs of different types of audio output devices 3, further expanding the data expansion function of the docking station.

[0030] It needs to be further explained that, such as Figure 5 and Figure 6 As shown, the motherboard 17 also integrates a listening interface 15.

[0031] In this system, by connecting the monitoring headphones 6 to the monitoring interface 15, the control chip 14 controls the monitoring interface 15 to output audio data to the monitoring headphones 6. The audio data is then played through the monitoring headphones 6. After wearing the monitoring headphones 6, the user can monitor the audio data transmitted from the docking station, which facilitates the control of the audio playback effect during the performance.

[0032] It needs to be further explained that, as shown in Figure 7 and Figure 8 As shown in the figure, the audio output device 3 has the same structure as the expansion dock body 1. The audio input port 11 of the audio output device 3 is connected to the second audio output port 13 of the expansion dock body 1 for audio data transmission, thereby forming an audio data transmission link 4 outside the expansion dock body 1.

[0033] When using the expansion dock, an audio output device 3 with the same structure as the expansion dock body 1 can be connected to the expansion dock body 1. The second audio output port 13 on the expansion dock body 1 is connected to the audio input port 11 on the audio output device 3, so that audio data can be transmitted to the audio output device 3. The second audio output port 13 on the audio output device 3 further expands the audio data, forming an audio data transmission link 4 with multiple audio data output branches. This is equivalent to increasing the number of external audio output devices 3 that the original expansion dock can connect to, thereby providing users with more ways to play and display audio when using the expansion dock.

[0034] Specifically, such as Figure 7 and Figure 8 As shown, the audio data transmission link 4 consists of at least two or more audio output devices 3, which are sequentially connected through the second audio output port 13 of one audio output device 3 to the audio input port 11 of another audio output device 3.

[0035] As the number of audio output modules connected to the main body 1 of the expansion dock on the audio data transmission link 4 increases, the number of second audio output ports 13 on the audio data transmission link 4 will increase, thereby enabling more smart devices to connect and allowing more smart devices to obtain the audio data transmitted by the audio input device 2.

[0036] It needs to be further explained that, such as Figure 1 As shown, the main board 17 of the expansion dock is provided with a power supply chip 16 that is connected to the power supply interface 12 and controls the charging power of the second audio output port 13.

[0037] The power supply chip 16 can control the power supply to each second audio output port 13 after the power supply interface 12 is connected to the power supply, thereby reasonably distributing the working voltage of the second audio output port 13 so that each second audio output port 13 can stably output audio data.

[0038] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
