DETAILED DESCRIPTION

[0047] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0048] See also Figure 1-Figure 7 , the present invention provides a technical solution:

[0049] A mobile video conferencing device that is easy to transport, comprising:

[0050] A connecting shell 100, wherein two symmetrically distributed baffles 120 are fixedly connected to the top of the connecting shell 100, a mounting shell 110 located between the two baffles 120 is disposed on the top of the connecting shell 100, and a screen 130 and a camera 140 are disposed on the surface of the mounting shell 110;

[0051] The top of the connecting shell 100 is provided with an installation cavity, a microphone 170 is arranged inside the installation cavity, and an adjustment component 200 is arranged inside the installation cavity;

[0052] Among them, the adjustment component 200 includes a mounting plate 2302 fixedly connected to the inner wall of the mounting cavity, the surface of the mounting plate 2302 is provided with evenly distributed sound holes 2303, the bottom of the mounting plate 2302 is fixedly connected with a first sound insulation cotton 2304, the bottom of the first sound insulation cotton 2304 is provided with a connecting plate 2305, the surface of the connecting plate 2305 is provided with a first through hole 2308 corresponding to the sound hole 2303, the first through hole 2308 is used to collect external audio, the surface of the connecting plate 2305 is provided with evenly distributed second through holes 2315, and the interior of the second through hole 2315 is provided with a sound-absorbing component for reducing echo interference.

[0053] Among them, the microphone 170, the screen 130 and the camera 140 are all relatively mature components in existing applications, and will not be described in detail here. The microphone 170 is used to receive external sound;

[0054] Under normal circumstances, the sound hole 2303 corresponds to the first through hole 2308, so that external sound can directly pass through the sound hole 2303 through the first sound insulation cotton 2304 to initially eliminate noise, and then pass through the first through hole 2308 to be collected by the microphone 170. At this time, the microphone 170 can better collect external audio and determine whether it belongs to an indoor environment or an outdoor environment based on the noise.

[0055] like Figure 1-Figure 7 As shown, the muffler assembly includes a mounting block 2311 fixedly connected to the inner wall of the second through hole 2315, the bottom of the mounting block 2311 is fixedly connected with an integrally formed connecting column, a muffler cavity is formed between the surface of the connecting column and the inner wall of the second through hole 2315, the inner wall of the muffler cavity is fixedly connected with evenly distributed protrusions 2314, the surface of the mounting block 2311 is provided with sound inlet holes 2313, and the inner wall of the sound inlet hole 2313 is provided with evenly distributed connecting holes 2312 that are connected to the muffler cavity;

[0056] The surface of the connecting plate 2305 is provided with evenly distributed third through holes, and the interior of the third through holes is provided with second sound insulation cotton 2309.

[0057] The surface of the connecting plate 2305 is fixedly connected to a separating ring 2306 which is slidably connected to the inner wall of the connecting shell 100, and the bottom of the separating ring 2306 is fixedly connected to a gear ring 2307. A motor 210 is arranged inside the connecting shell 100, and the output shaft of the motor 210 is fixedly connected to a gear 220 which is meshed with the gear ring 2307.

[0058] The angle between the extended line of the center of the second through hole 2315 and the extended line of the center of the first through hole 2308 is 20°, and the angle between the extended line of the center of the third through hole and the extended line of the center of the first through hole 2308 is 20°.

[0059] The top of the gear ring 2307 is fixedly connected with uniformly distributed trigger blocks 2310 , the number of the trigger blocks 2310 is six, one side of the trigger block 2310 is arranged in an inclined surface, and the trigger block 2310 corresponds to the third through hole.

[0060] A storage cavity coaxially arranged with the installation cavity is provided at the top of the connecting shell 100, and a connecting ring 230 is slidably connected to the inner wall of the storing cavity. A guiding slope is provided on the outer side of the connecting ring 230, and evenly distributed trigger rods 2301 are fixedly connected to the bottom of the connecting ring 230. The lower end of the trigger rod 2301 passes through the connecting shell 100 and contacts the surface of the gear ring 2307.

[0061] A spring 2316 is fixedly connected to the surface of the trigger rod 2301 , and the other end of the spring 2316 is fixedly connected to the inside of the connection shell 100 .

[0062] A control module 150 is disposed inside the connection shell 100, and connection cavities are provided on both sides of the connection shell 100, and a speaker 160 is disposed inside the connection cavity;

[0063] The control module 150 includes a controller, a storage medium, and a wireless transmission module;

[0064] The storage medium is provided with detection video and detection audio.

[0065] By starting the motor 210 to drive the gear 220 to drive the gear ring 2307 to rotate 20° clockwise, the second through hole 2315 can be adjusted to correspond to the first through hole 2308. At this time, it can act on the indoor environment. When the device is used in an indoor environment, a meeting is formed in the indoor environment, causing the audio played by the speaker 160 to be mixed with the human voices of the participants, which will affect the collection effect of the human voices of the participants. The second through hole 2315 is adjusted to a position corresponding to the first through hole 2308. At this time, the collected detection audio passes through the first through hole 2308 and is initially noise-reduced under the action of the first sound insulation cotton 2304. Then, the sound is introduced into the interior of the silencing cavity through the sound inlet hole 2313 and the connecting hole 2312. In this process, the sound wave can contact the protrusion 2314 and scatter to eliminate the sound. After the sound wave after the secondary silencing is collected by the microphone 170, it is eliminated by the frequency equalizer or the audio feedback automatic suppression device, which reduces the difficulty of eliminating the echo. In addition, the wireless transmission module includes a built-in echo elimination function, such as Skype;

[0066] The wind in the outdoor environment will cause the vibration of the diaphragm of the microphone 170 to generate noise, which affects the collection of the voices of the participants in the outdoor environment. When the third through hole is rotated to correspond to the first through hole 2308, the second sound insulation cotton 2309 can further reduce the noise of the wind. The first sound insulation cotton 2304 and the second sound insulation cotton 2309 can effectively reduce the natural wind from entering the installation cavity, thereby reducing the influence of the outdoor wind on the sound pickup of the microphone 170, and improving the sound pickup effect of the voices of the participants in the outdoor environment.

[0067] And in the process of the third through hole rotating to correspond to the first through hole 2308, the lower end of the trigger rod 2301 can be pushed by the inclined surface of the trigger block 2310, and in this process, the trigger rod 2301 can be driven to move upward and compress the spring 2316, and at this time, the connecting ring 230 can be driven to extend from the inside of the storage cavity. The guiding inclined surface of the connecting ring 230 can reduce the natural wind from entering the inside of the installation cavity, thereby improving the noise shielding effect of the natural wind outdoors.

[0068] A self-checking method for a video conferencing device comprises the following steps:

[0069] S1, open the installation shell 110 and turn on the screen 130, the microphone 170 and the speaker 160;

[0070] S2. The control module 150 plays the preset detection video and audio, and the microphone 170 collects external audio in real time. By playing the preset detection video and audio, it can be determined whether the screen 130 and the speaker 160 are damaged. The microphone 170 is set to pick up the preset audio and external audio;

[0071] S3, the controller analyzes whether there is noise in the audio collected by the microphone 170, and controls the motor 210 to perform corresponding work according to the analysis result. In the indoor environment, the echo generated by the preset audio will be collected by the microphone 170, while the echo generated by the preset audio in the outdoor environment is smaller and will not be collected by the microphone 170 after being eliminated by the first sound insulation cotton 2304. However, the natural wind in the outdoor environment will cause the vibration membrane of the microphone 170 to vibrate and generate noise, affecting the collection of the voices of the participants in the outdoor environment;

[0072] S4. After the adjustment is completed by the adjustment component 200, a video conference is established through the wireless transmission module, the collected audio is analyzed by the control module 150, and the rotation angle of the connecting plate 2305 is adjusted by the motor 210 to adapt to the outdoor environment or the indoor environment, thereby improving the sound pickup quality of the video conference.

[0073] It should be noted that the screen 130, camera 140, speaker 160, microphone 170, motor 210, storage medium, controller and wireless transmission module in the above description are all devices with relatively mature application of existing technologies. Specific models can be selected according to actual needs. At the same time, the screen 130, camera 140, speaker 160, microphone 170, motor 210, storage medium, controller and wireless transmission module can be powered by a built-in power supply or by AC power. The specific power supply method is selected according to the situation and will not be elaborated here.

[0074] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the statement "comprise one..." do not exclude the presence of other identical elements in the process, method, article or device including the elements.
