In this regard, the setting of a large number of inverters and power adapters not only increases the equipment cost of the mobile recording and broadcasting equipment, but also increases the complexity of the power supply architecture of the mobile recording and broadcasting equipment, which is not conducive to the integration of the mobile recording and broadcasting equipment, and limits the promotion of the mobile recording and broadcasting equipment.

[0028] The embodiments of the present application are further described in detail below in conjunction with the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are only used to explain the embodiments of the present application, rather than to limit the embodiments of the present application. It should also be noted that, for ease of description, only the parts related to the embodiments of the present application rather than all structures are shown in the accompanying drawings, and those skilled in the art should be able to think of it after reading the specification of this application that as long as the technical features do not contradict each other, any combination of the technical features can constitute an optional implementation method.

[0029] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable when appropriate, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally a class, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally represents that the objects associated before and after are in an "or" relationship. In the description of the present application, "multiple" means two or more, and "several" means one or more.

[0030] Mobile recording and broadcasting equipment can be moved around the venue and complete the recording of media files. For example, in a classroom scenario for practical training, for the teaching process of practical courses, users can use mobile recording and broadcasting equipment to record the teaching process in real time for live broadcast or video playback. However, due to the unreasonable configuration of traditional mobile recording and broadcasting equipment, mobile recording and broadcasting equipment needs to use an inverter to convert the connected AC power into DC power, and use a power adapter to achieve the conversion of the corresponding voltage value to adapt to the sub-devices on it.

[0031] For example, the speaker of the mobile recording and broadcasting equipment in the related art needs to be connected to 220V AC power. If it is powered by a battery, an inverter needs to be set up to convert the DC power provided by the battery into AC power, and the voltage conversion is completed through a power adapter to meet the rated voltage requirements of the speaker. For another example, the recording and broadcasting host of the mobile recording and broadcasting equipment in the related art needs to be connected to DC power, and a power adapter needs to be set up to achieve voltage conversion to meet the rated voltage requirements of the recording and broadcasting host.

[0032] Therefore, when powering sub-devices such as speakers and recording and broadcasting hosts, mobile recording and broadcasting equipment needs to use inverters and power adapters to adapt to the corresponding voltage type and rated voltage of each sub-device. However, this also leads to higher equipment costs for mobile recording and broadcasting equipment and increases the complexity of its power supply architecture.

[0033] In this regard, the present application provides a mobile recording and broadcasting device, the power supply architecture of which is less complex than that of related technologies, and power supply can be achieved without too many inverters and power adapters. Therefore, the mobile recording and broadcasting device of the present application can not only move within a venue and complete the recording of media files, but also reduce the cost of the device.

[0034] In one embodiment of the present application, the mobile recording and broadcasting device includes a recording and broadcasting host, a speaker and a battery module. The recording and broadcasting host is provided with a functional interface, which is used to provide a working voltage for an external device connected to the recording and broadcasting host; and the speaker is connected to an audio interface on the recording and broadcasting host so that the recording and broadcasting host can play audio through the speaker, and the speaker and the recording and broadcasting host have the same power supply voltage to be connected, that is, the speaker and the recording and broadcasting host use the same rated voltage.

[0035] In addition, a power switch is provided at the output end of the battery module, which is connected to the first power interface corresponding to the recording and broadcasting host, and the power switch is also connected to the second power interface corresponding to the speaker. The power switch is used to control whether the first power interface and the second power interface are connected to provide a power supply voltage.

[0036] It is understandable that in the mobile recording and broadcasting equipment, the battery module is used as the power supply for the speaker and the recording and broadcasting host, and the power supply voltage output by the battery module is adapted to the rated voltage of the speaker and the recording and broadcasting host, that is, the selected speaker and the recording and broadcasting host are both powered by direct current, and the rated voltages of the two are the same, and the voltage output by the selected battery module is the same as the above-mentioned rated voltage. The power switch plays the role of on-off control, that is, when the power switch is in the closed state, the speaker and the recording and broadcasting host can both access the power supply voltage provided by the battery module; and when the power switch is in the open state, the speaker and the recording and broadcasting host are not connected to the power supply.

[0037] In this regard, it can be imagined that, in actual use, the user can control the state of the power switch, that is, control the power switch to be closed or open, to control whether to supply power to the recording and broadcasting host and the speaker, and since the recording and broadcasting host is provided with a functional interface to connect external devices, the power switch can also realize the function of turning on and off the mobile recording and broadcasting device, and then when it is necessary to start recording of media files, the user can turn on the mobile recording and broadcasting device by closing the power switch to facilitate recording.

[0038] Exemplarily, the mobile recording and broadcasting host uses a 24V DC powered speaker and a recording and broadcasting host, and accordingly, the power output of the battery module as a power supply is 24V DC. The power switch is arranged at the output end of the battery module, and is also connected to the first power interface corresponding to the recording and broadcasting host and the second power interface corresponding to the speaker, respectively. When the power switch is in a closed state, the first power interface and the second power interface can both be connected to the supply voltage, so as to connect the speaker and the recording and broadcasting host to the power supply.

[0039] Figure 1 This is a schematic diagram of the power supply architecture of a mobile recording and broadcasting device provided in an embodiment of the present application. As shown in the figure, when the mobile recording and broadcasting device in the embodiment of the present application is used, the battery module 110 is connected to the external power supply 100 through a corresponding power adapter and a charging cable, such as a 220V AC power supply, so as to charge the battery module 110, so that the mobile recording and broadcasting can work in a battery-powered manner. In this regard, the external power supply 100 and the battery module 110 can be disconnected, and the connection is disconnected if the battery-powered mode is used after charging is completed.

[0040] The output end of the battery module 110 is connected to the power switch 111, and the power switch 111 is also connected to the recording and broadcasting host 120 and the speaker 130, such as connecting the first power interface (not shown in the figure) corresponding to the recording and broadcasting host 120 and the second power interface (not shown in the figure) corresponding to the speaker 130. Therefore, in the working state of being powered by the battery, when the power switch 111 is in a closed state in the mobile recording and broadcasting device, the first power interface can connect the power supply voltage to the recording and broadcasting host 120, and similarly, the second power interface can connect the power supply voltage to the speaker 130.

[0041] Moreover, the recording and broadcasting host 120 is connected to the speaker 130 via the audio interface thereon, such as the speaker 130 is connected to the audio interface via an audio line to receive the audio signal output by the recording and broadcasting host 120. In addition, the recording and broadcasting host 120 is also provided with a plurality of functional interfaces, which are used to connect external devices so as to provide working voltage for the connected external devices through the recording and broadcasting host. For example, the recording and broadcasting host is provided with a USB (Universal Serial Bus) interface as a functional interface, so as to connect a USB device and provide power to the USB device.

[0042] It can be seen that the power supply architecture of the mobile recording and broadcasting equipment uses the battery module to directly power the recording and broadcasting host and the speakers, and the recording and broadcasting host powers the external devices through its functional interface, and the battery module does not need to be configured with an inverter or a power adapter to adapt to the power supply voltage of the speakers and the recording and broadcasting host, thereby reducing the equipment cost and the complexity of the power supply architecture, which is conducive to the integration of mobile recording and broadcasting equipment.

[0043] In some embodiments, the mobile recording and broadcasting device also includes a power prompt module, which is connected to the battery module to detect the battery power of the battery module. For example, the power prompt module obtains the current battery power of the battery module through a corresponding power detection circuit. Furthermore, when the battery power is less than a preset threshold, the power prompt module outputs an alarm ring to send a low-power alarm to the user, thereby reminding the user that the current power is low, so as to improve the user's experience.

[0044] In one embodiment, the power prompt module includes a buzzer, wherein the buzzer will emit an alarm ring when it is in a working state. Therefore, the power prompt module can be provided with a corresponding buzzer circuit to respond to the detection result of the battery power. For example, the buzzer is connected to a corresponding switching transistor (such as an NPN transistor, a PNP transistor, etc.), and the control end of the switching transistor receives an electrical signal to control its conduction when the battery power is less than a preset threshold, and then the switching transistor enters a conducting state to make the buzzer in a working state, so that the buzzer outputs an alarm ring, that is, the buzzer-related circuit structure is simple, which helps to reduce the cost of the equipment. In this regard, the alarm ring output by the buzzer can be used as a low-power alarm prompt tone for a mobile recording and broadcasting device. It can be imagined that when the low-power alarm prompt tone is triggered, the user can trigger it to be turned off through the touch button on the LCD screen of the device.

[0045] In one embodiment, the power prompt module also includes a power display screen, which is connected to the battery module. The power display screen can display the acquired battery power, that is, the power display screen is used to display the battery power of the battery module in real time, such as displaying the battery power in digital style and / or graphic style. It can be understood that the power prompt module can obtain the battery power of the current battery module through the corresponding power detection circuit, and accordingly, the detection result can be displayed through the power display screen, so that the user can learn the power information and charge in time.

[0046] In one embodiment, the functional interfaces on the recording and broadcasting host include a USB (Universal Serial Bus) interface, a DMIC (Digital Microphone Interface) interface, and a POE (Power over Ethernet) interface. Among them, the USB interface is used to connect an external device, and the external device adopts a USB power supply method. Accordingly, the recording and broadcasting host can power the connected external device through the USB interface thereon. For example, in one embodiment, the external device is a wireless screen transmission module. It can be imagined that the wireless screen transmission module is connected to the HDMI (High Definition Multimedia Interface) interface on the recording and broadcasting host to receive HDMI signals, and the wireless screen transmission module is also connected to the USB interface on the recording and broadcasting host. The recording and broadcasting host can provide working voltage for the wireless screen transmission module through the USB interface.

[0047] The DMIC interface is used to connect a microphone and provide power to the microphone after it is connected. The POE interface is used to connect a network device, and the recording and broadcasting host can provide power to the network device through the POE interface. For example, if the network device is a camera, the recording and broadcasting host can connect to the camera through the POE interface and provide power to the camera.

[0048] It is conceivable that the functional interface on the recording and broadcasting host can only provide working voltage to external devices, network devices, etc. after the recording and broadcasting host is connected to the power supply voltage provided by the battery module. Moreover, the functional interface of the recording and broadcasting host is such as a USB interface. Accordingly, a step-up and step-down unit such as a step-up and step-down chip and a BUCK step-down circuit is set on the USB interface so that the USB interface can provide a 5V working voltage.

[0049] Therefore, the recording and broadcasting host can provide working voltage for external devices such as external devices and network devices through its functional interface, so that the recording and broadcasting host can be flexibly connected to different devices, which helps to improve the utilization efficiency of the battery module.

[0050] In some embodiments, the battery module in the mobile recording and broadcasting device is connected to an external power source through a power adapter and a charging cable to charge the battery in the battery module. The battery module supplies power to the speaker and the recording and broadcasting host through the output terminal thereon. It can be understood that the power adapter is used to convert 220V AC power into DC power that matches the rated voltage of the battery module. For example, if the rated voltage of the battery module is 24V, the power adapter converts 220V AC power into 24V DC power to charge the battery module. Therefore, the mobile recording and broadcasting device uses a rechargeable battery module, which does not require frequent battery replacement, and helps to improve battery utilization.

[0051] The mobile recording and broadcasting device includes a mobile cart, so that the mobile recording and broadcasting device can be driven to move in the application place by the mobile cart, so as to meet the recording and broadcasting needs of users. In some embodiments, the mobile cart includes a base, a moving device and a support column, wherein the moving device is arranged at the bottom of the base, and the moving device is used to drive the mobile recording and broadcasting device to move. For example, in one embodiment, a plurality of moving devices are arranged at the bottom of the base, such as the moving device is a universal wheel, and the plurality of universal wheels can be respectively arranged at different positions of the base, so that the mobile recording and broadcasting device can move smoothly.

[0052] The support column is arranged on the base, and a boom bracket is arranged on the top of the support column. It is understandable that the support column of the mobile recording and broadcasting device can be used to set other sub-devices, such as embedding a speaker inside the support column, setting the recording and broadcasting host on the support column, for example, setting it on one side of the support column. Of course, other devices can also be set on the support column, such as setting a storage table on the support column to place a microphone, a controller, etc.

[0053] Moreover, the boom bracket on the support column is provided with a movable end, which can be moved closer to or farther from the support column in the vertical and horizontal directions. Correspondingly, the camera can be on the movable end, so that the orientation of the camera can be adjusted through the movable end, so as to better record the video. In addition, the battery module is also embedded in the support column to protect the battery module by the support column.

[0054] In this regard, mobile recording and broadcasting equipment can integrate sub-devices such as speakers and recording and broadcasting hosts through a mobile cart, and the battery modules on it can power the sub-devices. Then, by using mobile devices, the mobile recording and broadcasting equipment can be moved within the application site, thereby meeting the recording and broadcasting needs at different locations.

[0055] For example, in one embodiment, the boom support includes a first connecting rod and a second connecting rod, wherein the first end of the first connecting rod is rotatably connected to the support column, so that the second end of the first connecting rod can rotate with the first end of the first connecting rod as the axis. In addition, the second end of the first connecting rod is movably connected to the first end of the second connecting rod, so that the second end of the second connecting rod can swing relative to the first end of the second connecting rod in the vertical direction, and in the horizontal direction, the second end of the second connecting rod can also rotate with the first end of the second connecting rod as the axis. The camera is movably connected to the second end of the second connecting rod, and the second connecting rod can drive the camera to move in the vertical direction and the horizontal direction, so as to flexibly move the camera to the corresponding position for shooting.

[0056] Therefore, through the setting of the boom bracket, the mobile recording and broadcasting equipment can meet the shooting requirements of multiple different shooting angles, so that the mobile recording and broadcasting equipment can be used in more scenarios, which is conducive to the promotion and application of the mobile recording and broadcasting equipment.

[0057] Figure 2 This is a structural diagram of a mobile recording and broadcasting device provided in an embodiment of the present application. The mobile recording and broadcasting device includes a mobile cart, such as Figure 2 As shown, the mobile cart includes a support column 210, a base 220 and a moving device 230. The support column 210 is arranged on the base 220, and a boom bracket 240 is arranged at the top of the support column 210. The moving device 230 is arranged at the bottom of the base 220, and the moving device 230 is used to drive the mobile recording and broadcasting equipment to move.

[0058] The boom support 240 includes a first link 241 and a second link 242, wherein the first end of the first link 241 is rotatably connected to the support column 210, and the second end of the first link 241 can rotate around the first end of the first link 241. In addition, the second end of the first link 241 is movably connected to the first end of the second link 242, so that the second end of the second link 242 can swing relative to the first end of the second link 242 in the vertical direction, and the second end of the second link 242 can also rotate around the first end of the second link 242 in the horizontal direction, and the camera 250 is movably connected to the second end of the second link 242. Therefore, the camera 250 can be flexibly moved to a corresponding position for shooting, thereby helping to meet the recording needs of different users.

[0059] Figure 3A schematic diagram of the system architecture of a mobile recording and broadcasting device provided for an embodiment of the present application is shown in the figure. The battery (battery) in the battery module 110 can be connected to 220V AC power through a power adapter (charger) to charge it. The battery module 110 is also connected to a power display screen to display the current battery power of the battery through the power display screen. In addition, the battery module 110 is also connected to a buzzer, which is used to output an alarm ring when the battery is low in power, as a low power alarm prompt tone and inform the user, wherein the power value corresponding to the low power can be set according to actual conditions.

[0060] The output end of the battery module 110 is connected to the speaker 130 and the recording and broadcasting host 120 through the power switch 111, and then the battery is used to power the speaker 130 and the recording and broadcasting host 120. It can be imagined that the speaker 130 and the recording and broadcasting host 120 are both DC-powered devices, and the supply voltage of both is the rated voltage of the battery. The audio interface on the recording and broadcasting host 120 is connected to the speaker 130 through an audio cable to provide an audio signal to the speaker 130.

[0061] The recording and broadcasting host 120 is provided with a plurality of functional interfaces, such as a POE interface, a USB interface, an HDMI interface, etc. The POE interface on the recording and broadcasting host 120 can be used to connect devices such as cameras and microphones. As shown in the figure, the recording and broadcasting host 120 connects camera I and camera II through the POE interface thereon to power camera I and camera II and receive the image data captured by each camera. The USB interface can be used to connect USB devices, such as a wireless screen transmitter, which can also power the device while transmitting data. The HDMI interface can be used to connect a display so that the recording and broadcasting host 120 can transmit audio and video signals to the display through the HDMI interface for display. The recording and broadcasting host 120 can provide operating voltage for external devices such as external devices and network devices through the functional interface thereon, so that the recording and broadcasting host 120 can flexibly access different devices, which helps to improve the utilization efficiency of the battery module 110.
