[0010] Optionally, the first electrical connection structure is disposed on the main body, and also includes a third mounting structure and a connecting structure, with the conductive body disposed on the third mounting structure and electrically connected to the main body through the connecting structure.

[0012] Optionally, a speaker is provided with multiple connecting protrusions, and the number of connecting grooves is the same as the number of connecting protrusions. The multiple connecting protrusions and multiple connecting grooves are respectively provided in a one-to-one correspondence.

The mounting body is made of aluminum, and the control structure, the audio structure, and the power amplifier structure are disposed on the mounting body.

[0015] The beneficial effects of the multimedia all-in-one machine provided in this application are as follows: When the speaker needs to be connected to the main body, the connecting protrusion is first aligned with the connecting groove, and then the speaker is pushed towards the main body so that the connecting protrusion is inserted into the connecting groove, thereby achieving physical fixation; as the speaker moves, the first electrical connection structure and the second electrical connection structure also come into contact, thereby achieving circuit conduction. When the speaker needs to be separated from the main body, the speaker is pulled away from the main body until the connecting protrusion is completely pulled out of the connecting groove. At this time, the physical connection between the two is released, and the electrical connection is also disconnected simultaneously.

[0016] This application, through the coordinated cooperation of the connecting protrusion and the connecting groove, as well as the first electrical connection structure and the second electrical connection structure, enables rapid physical separation and electrical disconnection of the speaker and the main body, allowing both to be used independently. This not only improves ease of use but also facilitates direct maintenance of the faulty component in case of failure in either the speaker or the main body, without disassembling the entire multimedia all-in-one machine, thus reducing maintenance costs and improving maintenance convenience. Furthermore, it also enables rapid physical and electrical connection between the speaker and the main body, allowing them to work collaboratively, thus enabling the multimedia all-in-one machine to simultaneously complete image acquisition and audio output.

[0017] In addition, the above structural design also supports the flexible installation of external sound speakers according to environmental needs, meeting the audio requirements of different usage environments (such as conference rooms, classrooms, and outdoor live broadcasts), and expanding the application scenarios of multimedia all-in-one machines.

[0045] As described in the background section, a multimedia all-in-one machine is an intelligent device that integrates image acquisition, video processing, and audio output functions, and is commonly used in scenarios such as teaching, meetings, and live streaming. In related technologies, a multimedia all-in-one machine includes a main unit and speakers, but the two are usually fixed as a single unit and cannot be used separately.

[0046] Reference Figures 1 to 10 To address the aforementioned problems, according to one aspect of this application, an embodiment of this application provides a multimedia all-in-one machine. The multimedia all-in-one machine includes a main body 100 and a speaker 200. The main body 100 is used for image acquisition. One of the main body 100 and the speaker 200 is provided with a connecting protrusion 111, and the other is provided with a connecting groove 211. The speaker 200 is detachably connected to the main body 100 by inserting into or withdrawing from the connecting groove 211 through the connecting protrusion 111. One of the main body 100 and the speaker 200 is provided with a first electrical connection structure 300, and the other is provided with a second electrical connection structure 400. When the speaker 200 is connected to the main body 100, the speaker 200 is electrically connected to the main body 100 by contacting the first electrical connection structure 300 and the second electrical connection structure 400.

[0047] In this embodiment, the recording and broadcasting integrated device is used in a classroom or conference room. The external speaker 200 is a speaker, loudspeaker module, or speaker column. When the external speaker 200 is connected to the main body 100, the length direction of the external speaker 200 is parallel to the length direction of the main body 100. The first electrical connection structure 300 and the second electrical connection structure 400 are both conductive components. The first electrical connection structure 300 and the second electrical connection structure 400 are respectively fixedly installed on the main body 100 and the external speaker 200. When the external speaker 200 is connected to the main body 100, electrical conductivity and transmission of electrical signals are possible between the main body 100 and the external speaker 200. When the external speaker 200 is separated from the main body 100, the first electrical connection structure 300 and the second electrical connection structure 400 are also in a separated state.

[0048] When the speaker 200 needs to be connected to the main body 100, first align the connecting protrusion 111 with the connecting groove 211, then push the speaker 200 toward the main body 100 so that the connecting protrusion 111 is inserted into the connecting groove 211, thereby achieving physical fixation. As the speaker 200 moves, the first electrical connection structure 300 and the second electrical connection structure 400 will also come into contact, thereby achieving circuit conduction. When the speaker 200 needs to be separated from the main body 100, pull the speaker 200 away from the main body 100 until the connecting protrusion 111 is completely pulled out of the connecting groove 211. At this time, the physical connection between the two is released, and the electrical connection is also disconnected simultaneously.

[0049] This application, through the coordinated cooperation of the connecting protrusion 111 and the connecting groove 211, as well as the first electrical connection structure 300 and the second electrical connection structure 400, can quickly complete the physical separation and electrical disconnection of the sound amplifier 200 and the main body 100, allowing both to be used independently. This not only improves ease of use but also facilitates direct maintenance of the faulty component in case of failure in either the sound amplifier 200 or the main body 100, without disassembling the entire multimedia all-in-one machine, thus reducing maintenance costs and improving maintenance convenience. Furthermore, it can also quickly complete the physical and electrical connection between the sound amplifier 200 and the main body 100, enabling them to work together and allowing the multimedia all-in-one machine to simultaneously complete image acquisition and audio output.

[0050] In addition, the above structural design also supports the flexible installation of the external speaker 200 according to environmental requirements, meeting the audio needs of different usage environments (such as conference rooms, classrooms, and outdoor live broadcasts), and broadening the application scenarios of the multimedia all-in-one machine.

[0051] In addition, when the speaker 200 is connected to the main body 100, the surface of the speaker 200 near the main body 100 is in contact with the surface of the main body 100 near the speaker 200, so that the exposed connecting wires or exposed structures are not visible from the outside, achieving a simple and beautiful effect.

[0052] Reference Figures 1 to 8 In one embodiment, a connecting protrusion 111 is provided on the main body 100, and a connecting groove 211 is provided on the sound amplifier 200. It is understood that the connecting protrusion 111 may also be provided on the sound amplifier 200, and the connecting groove 211 may be provided on the main body 100.

[0053] The connecting protrusion 111 is provided on the main body 100. The rigid structure of the main body 100 not only provides stronger physical support for the connecting protrusion 111, thus extending its service life, but also allows for easy replacement of the connecting groove 211 when the external speaker 200 is damaged, eliminating the need to replace the connecting protrusion 111 and reducing maintenance costs.

[0054] Reference Figures 1 to 8 In one embodiment, the connecting protrusion 111 includes a connecting body 1111 and a connecting body 1112. The connecting body 1111 is disposed on the main body 100 through the connecting body 1112. The projection surface of the connecting body 1111 onto the main body 100 covers the projection surface of the connecting body 1112 onto the main body 100.

[0055] In this embodiment, the connecting body 1111 is disposed on the connecting body 1112, and the connecting body 1112 is disposed on the main body 100. For ease of manufacturing and processing, the connecting body 1111 and the connecting body 1112 are integrally formed parts. The shape of the connecting protrusion 111 is T-shaped. It can be understood that the shape of the connecting protrusion 111 can also be L-shaped, T-shaped or other stepped shapes.

[0056] The connecting body 1111 and the connecting body 1112 form a stepped structure, which not only enables multi-level mechanical limiting when the connecting protrusion 111 is inserted into the connecting groove 211, thereby strengthening the connection strength between the sound amplifier 200 and the main body 100; at the same time, the stepped connecting protrusion 111 also has an anti-misinsertion function, which can only be adapted to the connecting groove 211 in the step sequence when inserted, avoiding damage to the connecting protrusion 111, the connecting groove 211, the first electrical connection structure 300 and the second electrical connection structure 400 due to reverse insertion.

[0057] Reference Figures 1 to 8 In one embodiment, the main body 100 includes a first mounting structure 110, and the connecting protrusion 111 and the first mounting structure 110 are integrally formed.

[0058] In this embodiment, the first mounting structure 110 is the side cover of the main body 100. It can be understood that the first mounting structure 110 may also be other structures of the main body 100.

[0059] The one-piece molding design not only avoids the weak point of the joint between the connecting protrusion 111 and the first mounting structure 110, reducing the risk of fracture caused by stress concentration, but also eliminates the need for additional assembly, reducing assembly time and cost.

[0060] Reference Figures 1 to 8 In one embodiment, the main body 100 is provided with a limiting structure 112, and when the first electrical connection structure 300 contacts the second electrical connection structure 400, the sound speaker 200 stops sliding by contacting the limiting structure 112.

[0061] In this embodiment, the limiting structure 112 is an L-shaped limiting plate. The limiting structure 112 is fixedly installed on the surface of the first mounting structure 110 with the connecting protrusion 111 by connecting screws. The limiting structure 112 is located on one side of the connecting protrusion 111.

[0062] The limiting structure 112 restricts the continued sliding of the speaker component 200, ensuring precise alignment when the first electrical connection structure 300 and the second electrical connection structure 400 come into contact, thus preventing poor contact or short circuits caused by excessive sliding. Simultaneously, the limiting structure 112 also provides physical locking, ensuring a stable connection between the speaker component 200 and the main body 100. Furthermore, the feedback when the speaker component 200 contacts the limiting structure 112 provides a clear indication to the user that the electrical connection is established, making the connection process visual.

[0063] Reference Figures 1 to 8 In one embodiment, the sound external speaker 200 includes a second mounting structure 210, a connecting groove 211 disposed in the second mounting structure 210, the second mounting structure 210 being a plastic part, and the connecting protrusion 111 being a metal part.

[0064] In this embodiment, the sound external speaker 200 also includes a receiving body 220, and a second mounting structure 210 is disposed on the receiving body 220 and serves as a side plate of the receiving body 220. It is understood that the second mounting structure 210 may also be a metal part, and the connecting protrusion 111 may be a plastic part, or both the second mounting structure 210 and the connecting protrusion 111 may be metal or plastic parts.

[0065] On the one hand, the fact that the second mounting structure 210 is made of plastic not only makes it easy to manufacture and process the connecting groove 211 on it, but also reduces the manufacturing cost and weight of the sound amplifier 200; in addition, it also serves as insulation, effectively preventing accidental short circuits when the sound amplifier 200 is electrically connected to the main body 100.

[0066] On the other hand, the structural design of the connecting protrusion 111 being a metal part not only improves the mechanical strength of the connecting protrusion 111, but also improves the stability of the connection between the sound amplifier 200 and the main body 100.

[0067] Reference Figures 9 to 12 In one embodiment, the first electrical connection structure 300 includes a conductive body 310, and the second electrical connection structure 400 is a conductive spring; when the first electrical connection structure 300 and the second electrical connection structure 400 are in contact, the conductive body 310 and the second electrical connection structure 400 are pressed together.

[0068] In this embodiment, the guide body is a conductive post or conductive block, and the conductive spring is a metal part; it can be understood that the second electrical connection structure 400 can also be a spring pin, an elastic conductive strip, a corrugated conductive spring, or a cantilever beam elastic contact.

[0069] The first electrical connection structure 300 and the second electrical connection structure 400 are made in contact by the conductive body 310 abutting against the second electrical connection structure 400. This structural design not only improves the reliability of the electrical connection between the first electrical connection structure 300 and the second electrical connection structure 400, but also compensates for assembly errors and avoids poor contact due to positional deviations. In addition, the elastic abutment can also form a buffer, improve the shock resistance of the contacting first electrical connection structure 300 and the second electrical connection structure 400, and prevent the contacting first electrical connection structure 300 and the second electrical connection structure 400 from breaking apart.

[0070] Reference Figure 1 as well as Figures 9 to 12 In one embodiment, a first electrical connection structure 300 is disposed on the main body 100, and also includes a third mounting structure 320 and a connecting structure 330. A conductive body 310 is disposed on the third mounting structure 320 and is electrically connected to the main body 100 through the connecting structure 330.

[0071] In this embodiment, the second electrical connection structure 400 is disposed on the external speaker component 200. Specifically, the second electrical connection structure 400 is disposed on the outside of the external speaker component 200 by connecting screws. The third mounting structure 320 is a mounting plate, which is fixedly mounted on the main body component 100 by connecting screws. The connecting structure 330 is a connecting stud and is electrically connected to the main body component via wires. Furthermore, to ensure that the conductive body 310 and the connecting structure 330 do not interfere with each other, the conductive body 310 and the connecting structure 330 are respectively disposed on two opposing surfaces of the third mounting structure 320. It can be understood that the first electrical connection structure 300 may also be disposed on the external speaker component 200, and the second electrical connection structure 400 may be disposed on the main body component 100.

[0072] The third mounting structure 320 provides mounting positions for the conductive body 310 and the connecting structure 330, ensuring the fitting accuracy between the conductive body 310 and the second electrical connecting structure 400. The connecting structure 330 serves to conduct electrical signals, enabling a stable electrical connection between the conductive body 310 and the main body 100, thereby ensuring a stable electrical connection between the main body 100 and the external speaker 200.

[0073] Reference Figure 1 , Figure 4 as well as Figures 9 to 12 In one embodiment, the third mounting structure 320 is disposed inside the main body 100, the main body 100 is provided with a connecting hole 113 that connects the inside and outside of the main body 100, the conductive body 310 extends to the outside of the main body 100 through the connecting hole 113, and the connecting structure 330 is located inside the main body 100.

[0074] In this embodiment, the connecting hole 113 is a through hole provided on the first mounting structure 110. The third mounting structure 320 and the connecting structure 330 are provided inside the main body 100, which not only effectively protects the third mounting structure 320 and the connecting structure 330, thereby extending their service life; but also reduces the external protrusion of the main body 100, thereby reducing the overall volume of the main body 100; in addition, it also improves the appearance of the main body 100. Furthermore, the connecting hole 113 not only allows the conductive body 310 to pass from inside the main body 100 to the outside of the main body 100, but also serves to position the conductive body 310.

[0075] Reference Figure 1 as well as Figures 9 to 13 In one embodiment, a sound external speaker 200 is provided with two first electrical connection structures 300 and two second electrical connection structures 400. One of the two first electrical connection structures 300 is connected to the positive terminal and the other is connected to the negative terminal. The two second electrical connection structures 400 are respectively provided in a one-to-one correspondence with the two first electrical connection structures 300.

[0076] In this embodiment, two first electrical connection structures 300 are spaced apart along the length direction of the connecting protrusion 111, and two second electrical connection structures 400 are spaced apart along the length direction of the connecting groove 211.

[0077] The two first electrical connection structures 300 and the two second electrical connection structures 400, when used in conjunction, form a conductive circuit upon contact with each other, thereby ensuring a stable electrical connection between the main body 100 and the sound amplifier 200. Simultaneously, the two first electrical connection structures 300 and the two second electrical connection structures 400 also improve current carrying capacity and optimize electrical signal quality.

[0078] Reference Figures 9 to 12 In one embodiment, the first electrical connection structure 300 is a one-piece molded part. The one-piece molded design not only avoids the weak points of the joints between the conductive body 310, the third mounting structure 320 and the connection structure 330, reducing the risk of fracture caused by stress concentration, but also eliminates the need for additional assembly, reducing assembly time and cost.

[0079] Reference Figures 1 to 13 In one embodiment, a sound amplifier 200 is provided with a plurality of connecting protrusions 111, and the number of connecting grooves 211 is the same as the number of connecting protrusions 111. The plurality of connecting protrusions 111 and the plurality of connecting grooves 211 are respectively provided in a one-to-one correspondence.

[0080] In this embodiment, a sound amplifier 200 is provided with two connecting protrusions 111, and the two connecting protrusions 111 are spaced apart along a direction perpendicular to the length of the connecting protrusions 111. It can be understood that a sound amplifier 200 may also be provided with three connecting protrusions 111, four connecting protrusions 111, or other numbers of connecting protrusions 111, and the multiple connecting protrusions 111 may also be spaced apart along a direction intersecting the length of the connecting protrusions 111.

[0081] The multiple connecting protrusions 111 and connecting grooves 211 used in conjunction enhance the connection strength between the sound amplifier 200 and the main body 100, making the connection between the sound amplifier 200 and the main body 100 more stable.

[0082] Reference Figures 1 to 13 In one embodiment, the main body 100 includes an image acquisition structure 120, a sound pickup structure 130, and a mounting body 140, wherein the image acquisition structure 120 and the sound pickup structure 130 are disposed on the mounting body 140.

[0083] In this embodiment, the image acquisition structure 120 includes a camera 121 and a camera control board 122. The camera 121 is electrically connected to the camera control board 122, and the sound pickup structure 130 is a sound pickup circuit board.

[0084] The image acquisition structure 120 and the sound pickup structure 130 are integrated into the mounting body 140, which not only realizes synchronous audio and video acquisition and achieves a multi-functional integrated design, but also makes the overall structure of the multimedia all-in-one machine compact, facilitating installation and relocation.

[0085] Reference Figure 13 and Figure 14 In one embodiment, the main body 100 further includes a control structure 150, an audio structure 160, and a power amplifier structure 170 disposed on the mounting body 140. The image acquisition structure 120, the sound pickup structure 130, and the audio structure 160 are electrically connected to the control structure 150. The power amplifier structure 170 is electrically connected to the audio structure 160. The power amplifier structure 170 is electrically connected to the sound external speaker 200 through a first electrical connection structure 300 and a second electrical connection structure 400.

[0086] In this embodiment, the control structure 150 is a control circuit board, the audio structure 160 is an audio circuit board, and the power amplifier structure 170 is a power amplifier circuit board; the camera control board 122 in the image acquisition structure 120 is electrically connected to the control structure 150.

[0087] The aforementioned structural design integrates image acquisition, sound pickup, audio processing, and power amplification into a single unit. This not only reduces reliance on external devices and achieves a high degree of integration across multiple functions in the multimedia all-in-one machine, but also reduces the spacing between components, shortens the signal transmission path, lowers signal loss, and improves signal transmission stability and anti-interference capabilities. Furthermore, the control structure 150 centrally manages all modules, facilitating synchronized audio and video triggering.

[0088] Reference Figures 1 to 15 In one embodiment, the mounting body 140 includes a front shell 141 and a mounting body 142. The front shell 141 is detachably mounted on the mounting body 142. The image acquisition structure 120 and the sound pickup structure 130 are disposed on the front shell 141. The mounting body 142 is made of aluminum. The control structure 150, the audio structure 160, and the power amplifier structure 170 are disposed on the mounting body 142.

[0089] In this embodiment, the front shell 141 is a plastic part, and is detachably mounted on the mounting body 142 by connecting screws. The image acquisition structure 120 and the sound pickup structure 130 are fixedly mounted on the front shell 141 by hardware brackets and connecting screws. The mounting body 142 is a mounting frame. The front shell 141 and the power amplifier structure 170 are fixedly mounted on the first position of the mounting body 142 by connecting screws, and the control structure 150 and the audio structure 160 are fixedly mounted on the second position of the mounting body 142. The first position and the second position of the mounting body 142 are spaced apart along the thickness direction of the mounting body 142. In addition, the first mounting structure 110 is fixedly mounted on the mounting body 142, and a mounting bracket 180 located inside the mounting body 142 is fixedly mounted thereon. The first electrical connection structure 300 is fixedly mounted on the mounting bracket 180 by connecting screws.

[0090] On the one hand, the front shell 141 is provided with an image acquisition structure 120 and a sound pickup structure 130, and the mounting body 142 is provided with a control structure 150, an audio structure 160 and a power amplifier structure 170, and the front shell 141 is detachably mounted on the mounting body 142; the above structural design makes the front shell 141 and the mounting body 142 form independent detachable units, which facilitates precise maintenance or replacement of the image acquisition structure 120 and the sound pickup structure 130 or the control structure 150, the audio structure 160 and the power amplifier structure 170.

[0091] On the other hand, the aluminum structure of the mounting body 142 not only reduces the initial development cost, but also gives the mounting body 142 characteristics such as fast heat dissipation and the ability to withstand high operating temperatures.

[0092] Reference Figures 1 to 15In one embodiment, the main body 100 further includes a lens 190, two front covers 1100, a wiring cover 1110, a rear cover 1120, and a wall mount bracket 1130. The lens 190 is disposed on the surface of the front cover 141 away from the mounting body 142 and covers the camera 121. The two front covers 1100 are respectively fixedly installed on the surface of the front cover 141 near the mounting body 142 along the length direction of the front cover 141. The rear cover 1120 is disposed on the surface of the mounting body 142 away from the front cover 141 and blocks the opening of the mounting body 142. The wall mount bracket 1130 is fixedly installed on the surface of the rear cover 1120 away from the mounting body 142.

[0093] In addition, the external speaker 200 also includes a mounting bracket 230, which is used to install on a fixed object such as a wall. The receiver 220 is installed on the fixed object such as a wall through the mounting bracket 230.

[0094] Reference Figures 1 to 15 In one embodiment, there are two external speaker components 200. Two opposing surfaces of the main body 100 are provided with connecting protrusions 111 and a first electrical connection structure 300. The two external speaker components 200 are respectively installed on opposite sides of the main body 100 through the engagement of the connecting protrusions 111 and connecting grooves 211. The two external speaker components 200 are electrically connected to the main body 100 through the contact between the first electrical connection structure 300 and the second electrical connection structure 400. It is understood that the number of external speaker components 200 can also be three, four, or more, depending on actual needs, and is not limited here.

[0095] In summary, the multimedia all-in-one machine provided in this embodiment has at least the following beneficial technical effects: When the speaker 200 needs to be connected to the main body 100, the connecting protrusion 111 is first aligned with the connecting groove 211, and then the speaker 200 is pushed towards the main body 100, so that the connecting protrusion 111 is inserted into the connecting groove 211, thereby achieving physical fixation; as the speaker 200 moves, the first electrical connection structure 300 and the second electrical connection structure 400 will also come into contact, thereby achieving circuit conduction. When the speaker 200 needs to be separated from the main body 100, the speaker 200 is pulled away from the main body 100 until the connecting protrusion 111 is completely pulled out of the connecting groove 211. At this time, the physical connection between the two is released, and the electrical connection is also disconnected simultaneously.

[0096] This application, through the coordinated cooperation of the connecting protrusion 111 and the connecting groove 211, as well as the first electrical connection structure 300 and the second electrical connection structure 400, enables rapid physical separation and electrical disconnection of the speaker unit 200 and the main body 100, allowing both to be used independently. This not only improves ease of use but also facilitates direct maintenance of the faulty component in case of failure in either the speaker unit 200 or the main body 100, without disassembling the entire multimedia all-in-one machine, thus reducing maintenance costs and improving maintenance convenience. Furthermore, it also enables rapid physical and electrical connection between the speaker unit 200 and the main body 100, allowing them to work collaboratively, enabling the multimedia all-in-one machine to simultaneously complete image acquisition and audio output. In addition, the above structural design supports flexible installation of the speaker unit 200 according to environmental requirements, meeting the audio needs of different usage environments (such as conference rooms, classrooms, and outdoor live streaming), thus broadening the application scenarios of the multimedia all-in-one machine.

[0097] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. It should be noted that, for those skilled in the art, several equivalent obvious modifications and / or equivalent substitutions can be made without departing from the technical principles of this application, and these obvious modifications and / or equivalent substitutions should also be considered within the scope of protection of this application.
