Description

Technical Field

[0001] This application relates to the field of conference equipment technology, and more particularly to a conference device. Background Technology

[0002] In related technologies, there is a type of conference equipment equipped with components such as speakers, microphones, and antennas. The antenna of the conference equipment generally transmits energy through direct power supply. Specifically, an RF chip is set on the circuit board, and conductive components such as springs or conductive foam are set between the circuit board and the housing with gaps. The RF chip is electrically connected to the housing by abutting against the power supply positions located on both sides of the gap. The RF signal emitted by the RF chip is transmitted to the gap on the housing through the springs or conductive foam, and then radiated through the gap.

[0003] However, during the installation of conductive components such as spring contacts or conductive foam, the conductive components need to contact the housing and slide along the housing to move to the power supply position on the housing. This installation method can easily cause the conductive components such as spring contacts or conductive foam to be damaged during the sliding process, which may lead to poor consistency and reliability of the conference equipment (poor consistency and reliability refer to performance fluctuations or failures of the conference equipment due to process or material problems). In addition, in order to ensure conductivity, the power supply position on the housing also needs to be laser-engraved or have gold-plated spring contacts welded on, which will also lead to higher costs for the conference equipment. Summary of the Invention

[0004] In view of this, the embodiments of this application aim to provide a conference device that can both improve the consistency and reliability of the conference device and reduce the cost.

[0005] To achieve the above objectives, embodiments of this application provide a conference device, including:

[0006] A housing with a receiving cavity and a power supply slot;

[0007] A coupled-feed antenna is disposed within the housing cavity, the coupled-feed antenna being spaced apart from the housing and facing the feed gap.

[0008] In one embodiment, the conference equipment includes a mounting bracket disposed within the receiving cavity, the coupled feed antenna being mounted on the mounting bracket, and the mounting bracket being slidably sleeved relative to the housing.

[0009] In one embodiment, the mounting bracket has a mounting surface that matches the shape of the coupled-feed antenna, and the coupled-feed antenna is attached to the mounting surface.

[0010] In one embodiment, the length L of the feed gap is: 0.45 times the wavelength ≤ L ≤ 0.5 times the wavelength, or the length L of the feed gap is: 0.25 times the wavelength ≤ L ≤ 0.5 times the wavelength;

[0011] And / or,

[0012] The width W of the feeding gap is: W ≤ 0.05 times the wavelength;

[0013] And / or,

[0014] The distance D between the coupled feed antenna and the feed gap is: D≤0.16 times the wavelength;

[0015] The wavelength in question is the operating frequency band wavelength.

[0016] In one embodiment, the housing has a first direction and a second direction that are perpendicular to each other, the first length dimension of the housing along the first direction is greater than the second length dimension along the second direction, and the conference device includes a speaker and a circuit board disposed within the receiving cavity, the circuit board being located on one side of the speaker along the first direction and extending along the first direction.

[0017] In one embodiment, the housing has a shell body that surrounds the receiving cavity. On a projection plane perpendicular to the first direction, the projection of the shell body surrounds the outer periphery of the projection of the receiving cavity, and the power supply gap is disposed on the shell body.

[0018] In one embodiment, the power supply gap extends circumferentially along the housing.

[0019] In one embodiment, the conference equipment includes a mounting bracket disposed within the receiving cavity, at least one of the speaker and the circuit board, and the coupled feed antenna are mounted on the mounting bracket, the feed gap is located on the side of the mounting bracket opposite to the circuit board along the second direction, and the coupled feed antenna is electrically connected to the circuit board via a flexible connector.

[0020] In one embodiment, the conference device further includes a Wi-Fi antenna, which and the coupled feed antenna are respectively disposed at the bottom and top of the housing along the first direction.

[0021] In one embodiment, the conference device further includes a base located on the side of the Wi-Fi antenna away from the coupled feed antenna along the first direction, and the housing is mounted on the base.

[0022] This application provides a conference device comprising a housing with a receiving cavity and a feeding slot, and a coupled feeding antenna disposed within the receiving cavity. The coupled feeding antenna is spaced apart from the housing and faces the feeding slot. Since the coupled feeding antenna transmits energy through an electromagnetic field, no conductive components such as springs or conductive foam are required for electrical connection between the coupled feeding antenna and the housing. Therefore, the consistency and reliability of the conference device are not affected by these conductive components. Furthermore, compared to conference devices of related technologies, the conference device of this embodiment can reduce costs by eliminating these conductive components. In other words, by incorporating a coupled feeding antenna, the conference device of this embodiment not only improves the consistency and reliability of the conference device but also reduces costs.

[0023] Other technical effects of this application are described in detail in the specific embodiments. Attached Figure Description

[0056] In the description of the embodiments of this application, it should be noted that the terms "first direction," "second direction," etc., indicate the orientation or positional relationship based on the appendix. Figure 2 The directions or positional relationships shown can include both "first direction" and "second direction". Figure 2The two opposing directions indicated by the bidirectional arrows at the corresponding directions are merely for the convenience of describing the embodiments of this application and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the embodiments of this application.

[0057] This application provides a conference device; please refer to [link / reference]. Figure 1 , Figure 3 , Figure 5 , Figures 13 to 15 The conference equipment includes a housing 101, a speaker 102, a microphone 103, and a circuit board 105.

[0058] The housing 101 has a receiving cavity 101a, within which at least one of the speaker 102, microphone 103, and circuit board 105 may be disposed. For example, Figure 1 and Figure 5 The speaker 102, microphone 103, and circuit board 105 shown are all housed within the receiving cavity 101a. In other embodiments, the conference equipment may also have other structures with receiving spaces outside the housing 101, and any one or any two of the speaker 102, microphone 103, and circuit board 105 may be housed within the receiving spaces of other structures. Please refer to... Figure 15 The conference equipment can be mounted on a mounting bracket 106 within the receiving cavity 101a. At least one of the speaker 102, microphone 103, and circuit board 105 can be mounted on the mounting bracket 106. The specific mounting method is not limited; for example, it can be a snap-fit, plug-in, adhesive bonding, or fastening connection using fasteners (such as screws).

[0059] Figure 15 The speaker 102, microphone 103 and circuit board 105 shown are all mounted on the mounting bracket 106. In some other embodiments, any one or any two of the speaker 102, microphone 103 and circuit board 105 may be mounted on the mounting bracket 106.

[0060] Figure 3 and Figure 13 The conference equipment shown also includes a base 107, which is located below the housing 101 and above the base 107. The base 107 can support the housing 101.

[0061] The base 107 may be at least partially disposed outside the housing 101. That is, a part of the base 107 may be disposed inside the housing 101 and another part may be disposed outside the housing 101, or the entire base 107 may be located outside the housing 101.

[0062] Please see Figure 14 , Figure 15 , Figure 19 and Figure 21 The conference equipment can be equipped with an anti-slip part 108 at the bottom of the base 107. The anti-slip part 108 is used to contact the support surface such as the table to stabilize the conference equipment and prevent it from tipping over in case of accident.

[0063] Figure 14 , Figure 15 , Figure 19 and Figure 21 The anti-slip component 108 shown is a suction cup, which can be attached to a support surface such as a desktop. In other embodiments, the anti-slip component 108 may also be an anti-slip mat with a certain friction, a mounting accessory capable of magnetic attraction, etc.

[0064] In other embodiments, the conference equipment may not have the anti-slip component 108, or the conference equipment may not have the base 107.

[0065] Please continue reading. Figure 13 , Figure 14 and Figure 19 The conference equipment can also be equipped with function buttons 114 and / or connection interfaces 115 on the base 107. The function buttons 114 are used to turn the conference equipment on and off, and to turn other control functions on and off. The connection interfaces 115 can be used for charging and / or data transmission of the conference equipment.

[0066] In some embodiments, a speaker 102 and / or a microphone 103 may also be provided on the base 107, and a circuit board 105 may also be provided on the base 107.

[0067] In some embodiments, please refer to Figures 3 to 5 , Figure 15 and Figure 16 The conference equipment can also be equipped with a lifting mechanism 113, which drives the housing 101 to rise and fall relative to the base 107.

[0068] The conference equipment can be in use when the housing 101 rises to the first preset position and in non-use when the housing 101 falls to the second preset position, or it can be in use when it rises to the first preset position and falls to the second preset position.

[0069] In addition, the lifting mechanism 113 can also be configured to drive the housing 101 to move to some or any position between the first preset position and the second preset position, thereby meeting the different height requirements of users.

[0070] It should be noted that for conference equipment with lifting mechanism 113, base 107 may also be at least partially located outside housing 101.

[0071] The specific structure of the lifting mechanism 113 is not limited; for example, please refer to [link to relevant documentation]. Figure 15 and Figure 16 The lifting mechanism 113 may include a drive motor 1131, a transmission assembly 1132, and a support rod 1133. Figure 15 and Figure 16 The drive motor 1131 and transmission assembly 1132 are disposed within the receiving cavity 101a of the housing 101. For example, the transmission assembly 1132 can be mounted on the mounting bracket 106. In other embodiments, the drive motor 1131 and transmission assembly 1132 can also be disposed within the base 107. The transmission assembly 1132 is connected to both the drive motor 1131 and the support rod 1133. The drive motor 1131 drives the transmission assembly 1132 to move, causing the support rod 1133 or the transmission assembly 1132 to raise or lower the housing 101 relative to the base 107.

[0072] Transmission connection refers to the mechanical connection method in a mechanical system that transmits power from a power source (such as the drive motor 1131 of this application) to an actuator (such as the support rod 1133 of this application).

[0073] Figure 16 The transmission assembly 1132 shown is a lead screw drive assembly, which includes a lead screw 11321, a slider 11322 threadedly connected to the lead screw 11321, and a guide member 11323 slidably connected to the slider 11322. A support rod 1133 is connected to the slider 11322. Rotation of the lead screw 11321 allows the slider 11322 and the lead screw 11321 to move linearly relative to each other along the axial direction of the lead screw 11321. Because... Figure 15 and Figure 16 The lead screw drive assembly shown is located in the receiving cavity 101a of the housing 101. The support rod 1133 is connected to the base 107. Therefore, during the rotation of the lead screw 11321, the support rod 1133 and the slider 11322 are actually kept relatively stationary. The lead screw 11321 drives the housing 101 to move by moving linearly relative to the slider 11322, thereby realizing the lifting and lowering of the housing 101 relative to the base 107.

[0074] In some other embodiments, if the lead screw drive assembly is located inside the base 107, the support rod 1133 can be directly or indirectly connected to the housing 101. During the rotation of the lead screw 11321, the slider 11322 drives the support rod 1133 to rise and fall by moving linearly relative to the lead screw 11321, thereby enabling the support rod 1133 to drive the housing 101 to rise and fall.

[0075] It should be noted that the transmission component 1132 is not limited to a lead screw transmission component. In other embodiments, the transmission component 1132 can also be any type of transmission component 1132 capable of linear motion, such as a gear and rack meshing transmission component.

[0076] In other embodiments, the lifting mechanism 113 may also be a telescopic component such as an electric cylinder or a pneumatic cylinder that can achieve telescopic function, or it may be a combination structure of a telescopic component such as an electric cylinder or a pneumatic cylinder and a support rod 1133. Alternatively, the lifting mechanism 113 may also include movable moving parts such as a movable pulley, and the lifting mechanism 113 achieves lifting through the movable parts such as the movable pulley.

[0077] In addition, the conference equipment can also use a detection component to locate the lifting height of the lifting mechanism 113.

[0078] The type of detection component is not limited. For example, the detection component may include a Hall sensor and a magnet. The Hall sensor may be disposed in the receiving cavity 101a, and the magnet may be disposed on the support rod 1133. During the lifting process of the lifting mechanism 113, the height of the lifting is positioned by the Hall effect.

[0079] In some other embodiments, the lifting mechanism 113 may not be equipped with a drive motor 1131. The lifting mechanism 113 can be raised and lowered manually. For example, the lifting mechanism 113 may be equipped with a mechanical limit structure with multiple positions, which can be manually adjusted to the corresponding position to achieve raising and lowering. Alternatively, the lifting mechanism 113 may be equipped with an elastic pressing type lifting structure, which can be raised by pressing and popping up.

[0080] Please continue reading. Figure 11 and Figure 12 The base 107 has an upper surface 107a facing the housing 101, the upper surface 107a having opposing first sides X1 and second sides X2. In some embodiments, please refer to... Figure 11 and Figure 12 The upper surface 107a can be inclined so that the first side X1 is higher than the second side X2. The end face 101a of the housing 101 facing the base 107 can be inclined in the same direction as the upper surface 107a. The end face 101a can be parallel to the upper surface 107a or not. The lifting mechanism 113 can be located on the first side X1 of the upper surface 107a.

[0081] Please see Figure 11When the conference equipment is in use, the housing 101 is spaced apart from the base 107, and a portion of the lifting mechanism 113 is located in the space between the housing 101 and the base 107. The projection of the lifting mechanism 113 onto the end face 101a in a direction perpendicular to the lifting direction at least partially falls within the end face 101a. For example, as... Figure 11 As shown, the lifting mechanism 113 is positioned perpendicular to the lifting direction. Figure 11 The dotted line in the figure represents the direction perpendicular to the lifting direction. The projection of the lifting mechanism 113 onto the end face 101a falls completely into the end face 101a. In other embodiments, only a portion of the projection of the lifting mechanism 113 falls into the end face 101a.

[0082] Please see Figure 12 When the lifting mechanism 113 is located on the first side X1 of the upper surface 107a, the user will generally face the second side X2 of the upper surface 107a towards themselves. This means that the side of the conference equipment corresponding to the second side X2 of the upper surface 107a is the front of the conference equipment. The end face 101a of the housing 101 facing the base 107 is tilted in the same direction as the upper surface 107a, which allows the end face 101a to at least partially cover the lifting mechanism 113, making it more aesthetically pleasing, especially when the tilt angle of the end face 101a relative to the horizontal plane is 9° to 15°. (Including endpoint values), and the lifting height of the lifting mechanism 113 is within a suitable range (for example, when the lifting height of the lifting mechanism 113 is less than or equal to 4cm), the end face 101a has a better shielding effect on the lifting mechanism 113, and a visual effect of the housing 101 floating above the base 107 can be formed on the front of the conference equipment (that is, the lifting mechanism 113 is basically not visible from the front of the conference equipment, and the housing 101 looks like it is suspended in the air), which not only helps to further improve the aesthetics of the conference equipment, but also provides users with a more novel user experience.

[0083] In some embodiments, please refer to Figure 3 When the conference equipment is in use, the housing 101 and the base 107 can have a certain preset distance, which can be 3cm, 4cm, 5cm, 6cm, 7cm, 8cm, 9cm, 10cm, etc., and is not specifically limited here.

[0084] When the conference equipment is not in use, housing 101 can be lowered by the lifting mechanism 113. (See [link to relevant documentation]). Figure 4When the housing 101 descends to the second preset position, the housing 101 can get as close as possible to the base 107, or even contact the base 107. In other words, the conference equipment is switched to a non-use state. From the appearance, the housing 101 and the base 107 roughly form a whole. This not only minimizes the size of the conference equipment in the lifting direction when it is not in use, making it easier to store, but also makes the conference equipment look more beautiful.

[0085] In addition, some components can be provided on the side of the housing 101 facing the base 107 and / or the side of the base 107 facing the housing 10 (the specific components will be described in the following embodiments). When the housing 101 descends to the second preset position, the housing 101 is as close as possible to the base 107, or even in contact with the base 107, which can shield these components, thereby preventing foreign objects from entering the components or providing better protection for the components.

[0086] Furthermore, the conference equipment may also include a detection unit and a control unit. The control unit can be a circuit board 105 or a separately configured control board. The detection unit is used to detect the placement status of the conference equipment. The detection unit can be, for example, an angle sensor, a horizontal gyroscope, etc. The placement status includes a balanced state and an unbalanced state. It should be noted that the balanced state refers to the base 107 being placed vertically on a supporting surface such as a table, with the housing 101 located above the base 107, that is, the vertical center line of the conference equipment is parallel to the vertical line. The unbalanced state refers to the state where the angle between the vertical center line of the conference equipment and the vertical line is greater than a preset angle. For example, the preset angle is 10 degrees. When the angle between the vertical center line of the conference equipment and the vertical line is greater than 10 degrees, the conference equipment enters the unbalanced state. Here, the vertical center line of the conference equipment is parallel to the lifting direction of the lifting mechanism 113, and the vertical line is a perpendicular line to the supporting surface such as the table.

[0087] The control unit is configured to control the lifting mechanism 113 to drive the housing 101 to a second preset position when the conference equipment is in an unbalanced state, thereby switching to a non-use state and protecting the components on the housing 101 and / or the base 107. This configuration further enhances the protection of the components on the housing 101 and / or the base 107, thus improving the reliability of the conference equipment.

[0088] In some embodiments, please refer to Figure 11A sensor 122 may also be provided on the side of the housing 101 facing the base 107. The sensor 122 may include a circuit board 1221 and a sensor body (not shown) disposed on the circuit board 1221. The sensor 122 may protrude from the bottom end face of the housing 101 or may not protrude from the bottom end face. The sensor 122 is used to detect whether there is a foreign object between the housing 101 and the base 107. When a foreign object is detected between the housing 101 and the base 107, the control system of the conference equipment may control the lifting mechanism 113 to stop running or control the lifting mechanism 113 to run in reverse. This can better avoid situations such as the housing 101 being pinched or foreign objects blocking the housing 101 and causing damage to the housing 101 during the descent of the housing 101.

[0089] The type of sensor 122 is not limited. For example, sensor 122 can be a pressure sensor, an infrared sensor, an ultrasonic sensor, etc.

[0090] Taking a pressure sensor as an example, during the descent of the housing 101, the pressure sensor can detect the pressure value of the end face 101a in real time. When the pressure value detected by the pressure sensor exceeds the preset pressure value, the control system can control the lifting mechanism 113 to stop operating, or the control system can first control the lifting mechanism 113 to stop operating, and then control the lifting mechanism 113 to reverse its operation, so that the housing 101 changes from descending to rising. In this way, the descent of the housing 101 can be stopped in time before the user feels obvious pain or before foreign objects squeeze the housing 101, thereby effectively improving the safety and reliability of the conference equipment.

[0091] The preset pressure value can be, for example, a force of less than 10N. Alternatively, the preset pressure value can be set according to the shape and type of the conference equipment to adjust the reliability of the conference equipment, thereby ensuring that the reliability and safety of the conference equipment are at their best.

[0092] For example, please refer to Figure 11 The pressure sensor body is electrically connected to circuit board 1221, which in turn is electrically connected to the main circuit board 105 of the conference equipment. Circuit board 1221 is mounted on end face 101a, and the sensor body is located on the side of circuit board 1221 facing away from end face 101a. This arrangement effectively reduces the space occupied by the sensor body within the housing 101, facilitating the miniaturization of the conference equipment. Furthermore, it improves the accuracy of pressure detection on end face 101a and the timeliness of control over the lifting mechanism 113, thereby enhancing the precision of control over the conference equipment and further improving its safety and reliability.

[0093] In some embodiments, please refer to Figure 11 A protective pad 123 may also be provided on the side of the housing 101 facing the base 107. The protective pad 123 may include, but is not limited to, a silicone pad.

[0094] During the descent of the housing 101, if a hand or foreign object is inserted between the housing 101 and the base 107, the protective pad 123 can provide a certain buffering effect by contacting the hand or foreign object. This not only reduces the pain caused by the housing 101 hitting the hand, but also reduces the chance of the housing 101 being damaged by hitting a foreign object.

[0095] The protective pad 12 may protrude from the bottom surface of the housing 101 or not. For conference equipment with sensor 122, the position and method of setting the protective pad 123 should not affect the normal detection function of sensor 122. Under the premise of not affecting the normal detection of sensor 122, the protective pad 123 can be set on the side of sensor 122 away from housing 101. If sensor 122 is a pressure sensor, the protective pad 12 is preferably protruding from the bottom surface so that the pressure sensor can accurately sense the pressure generated when the protective pad 12 comes into contact with a hand or foreign object.

[0096] In some other embodiments, the conference equipment may not have a lifting mechanism 113.

[0097] For conference equipment without a lifting mechanism 113, the base 107 can be directly connected to the housing 101, or the base 107 and the housing 101 can be connected by a support structure without a lifting function.

[0098] Speaker 102 is an energy conversion device that converts electrical signals into sound signals. (See also...) Figure 14 , Figure 15 and Figure 18 The loudspeaker 102 includes a housing 1021 and a diaphragm 1022 disposed in the housing 1021. The housing 101 has a first opening 101b that avoids the diaphragm 1022. The diaphragm 1022 is generally located inside the first opening 101b and is at a certain distance from the first opening 101b. The diaphragm 1022 converts electrical signals into sound signals through vibration. The sound signals are transmitted into the air through the first opening 101b, ultimately producing sound.

[0099] The location of the first opening 101b on the housing 101 is not limited; for example, please refer to [reference needed]. Figure 14 For a conference device with a base 107, the base 107 may be at least partially disposed outside the housing 101. The first opening 101b may face the part of the base 107 located outside the housing 101. The sound signal is emitted to the base 107 through the first opening 101b and then reflected by the base 107 or other components disposed on the base 107.

[0100] Additionally, please see Figure 4 For a conference setup with a lifting mechanism 113, and where the housing 101 can be roughly integrated with the base 107 under the drive of the lifting mechanism 113, the first opening 101b is oriented towards the part of the base 107 located outside the housing 101. Alternatively, when the housing 101 is lowered to the second preset position, the base 107 can block the first opening 101b, thereby providing a certain degree of protection for the speaker 102.

[0101] For conference equipment equipped with a pressure sensor, an opening corresponding to the first opening 101b can be provided on the circuit board 1221. The sound signal is emitted to the base 107 through the first opening 101b and the opening on the circuit board 1221. This avoids the circuit board 1221 from covering the first opening 101b and affecting the sound output of the speaker 102, while also increasing the contact area between the circuit board 1221 and the end face 101a, thereby improving the stability of the pressure sensor set on the end face 101a.

[0102] In some embodiments, please refer to Figure 13 and Figure 18 The speaker 102 can also be equipped with a passive diaphragm 1023. The number of passive diaphragms 1023 can be one or more, for example... Figure 18 The speaker 102 shown has two passive diaphragms 1023 located on opposite sides of the enclosure 1021. The passive diaphragms 1023 are fixed to the enclosure 1021 by means of adhesive or other methods. The enclosure 101 has a second opening 101c that avoids the passive diaphragms 1023, meaning the passive diaphragms 1023 are exposed at the second opening 101c. The passive diaphragms 1023 can vibrate, but are not used to convert electrical signals into sound signals. The purpose of the passive diaphragms 1023 is to provide a decorative visual effect through their vibration.

[0103] Microphone 103 is an energy conversion device that converts sound signals into electrical signals. Please refer to [link to relevant documentation]. Figures 13 to 15 , Figure 24 The housing 101 has a third opening 101d that avoids the microphone 103. External sounds can be transmitted into the microphone 103 through the third opening 101d, which means that the microphone 103 picks up sound through the third opening 101d.

[0104] The number of microphones 103 can be one or multiple; please refer to [link / reference]. Figures 13 to 15 , Figure 24When there are multiple microphones 103, the microphones 103 can be distributed in the receiving cavity 101a so that the conference equipment can pick up sound from multiple directions. In addition, the microphones 103 can be arranged in one layer or multiple layers. When the microphones 103 are arranged in multiple layers, it can further facilitate the conference equipment to pick up sound from more directions and / or angles.

[0105] The main circuit board 105 is electrically connected to the speaker 102 and the microphone 103 respectively.

[0106] Please see Figure 1 , Figure 5 and Figure 15 The conference equipment can also be equipped with a power supply component 104, which is electrically connected to the circuit board 105. The power supply component 104 is used to provide power to the conference equipment. The power supply component 104 includes, but is not limited to, a rechargeable battery. The power supply component 104 can be disposed in the receiving cavity 101a. The power supply component 104 can be mounted on the mounting bracket 106 or not.

[0107] In other embodiments, the conference equipment may not require a power supply component 104. For example, the conference equipment may be powered directly by an external power source, such as a power bank, a terminal device with reverse charging function, or a mains power source.

[0108] Please see Figure 1 The housing 101 has a first direction and a second direction that are perpendicular to each other. In some embodiments, please refer to [reference needed]. Figure 1 and Figure 5 The first length dimension of the housing 101 along the first direction can be greater than the second length dimension along the second direction. The circuit board 105 can be located on one side of the speaker 102 along the first direction, and the circuit board 105 extends along the first direction.

[0109] The second direction refers to one of the directions that is perpendicular to the first direction. The first and second directions can be completely perpendicular or basically perpendicular. Completely perpendicular means that the angle between the first and second directions is 90°. Basically perpendicular means that the angle between the first and second directions is close to 90°. For example, the angle between the first and second directions can be less than 90° and greater than or equal to 80°.

[0110] The circuit board 105 has mutually perpendicular length, width, and thickness directions. The length dimension of the circuit board 105 can be greater than or equal to its width dimension. The thickness dimension of the circuit board 105 is the smallest of the three dimensions. "Extending along the first direction" means that opposite sides of the circuit board 105 along its length direction face opposite ends of the housing 101 along the first direction.

[0111] The circuit board 105 has a component surface 105a, which refers to the side of the circuit board 105 used for mounting electronic components. The circuit board 105 can have only one component surface 105a (e.g., a single-sided circuit board 105), or two component surfaces 105a (e.g., a double-sided circuit board 105), or more than two component surfaces 105a (e.g., a multi-layer circuit board 105).

[0112] More preferably, the angle between the component surface 105a and the first direction can be 0° to 10° (including the endpoint value). For example, the angle between the component surface 105a and the first direction can be 0°, 3°, 5°, 8°, 10°, etc., which means that the component surface 105a can preferably be parallel or substantially parallel to the first direction.

[0113] The circuit board 105 is located on one side of the speaker 102 along the first direction so that the speaker 102 and the circuit board 105 and other components mainly occupy the space of the receiving cavity 101a in the first direction. The circuit board 105 extends along the first direction in order to minimize the space occupied by the circuit board 105 and other components in the second direction of the receiving cavity 101a, thereby adapting to the elongated shape of the housing 101.

[0114] "Elongated" means that the first length dimension of the housing 101 along the first direction is significantly larger than the length dimension in other directions (including but not limited to the second direction) perpendicular to the first direction, so that the housing 101 presents a relatively slender strip shape.

[0115] The housing 101 has a shell body 1011 that surrounds the receiving cavity 101a. For the elongated housing 101, on a projection plane perpendicular to the first direction, the projection of the shell body 1011 surrounds the outer periphery of the projection of the receiving cavity 101a. Figure 2 , Figures 6 to 8 The view shown is equivalent to the projection of the shell 1011 and the receiving cavity 101a onto a projection plane perpendicular to the first direction, that is, the shell 1011 is annular.

[0116] Please continue reading. Figure 2 , Figures 6 to 8 , Figure 13The cross-sectional shape of the shell 101 perpendicular to the first direction can be circular. That is, on the projection plane perpendicular to the first direction, the projection of the shell 1011 is annular, and correspondingly, the shell 101 is cylindrical.

[0117] In other embodiments, the cross-sectional shape of the shell 101 perpendicular to the first direction can be a polygon (including but not limited to triangles, rectangles, trapezoids, rhombuses, pentagons, etc.). That is, on the projection plane perpendicular to the first direction, the projection of the shell 1011 is a ring-shaped polygon, and correspondingly, the shell 101 is prism-shaped.

[0118] In other embodiments, the cross-sectional shape of the housing 101 perpendicular to the first direction can also be arc-shaped (including but not limited to semi-circular), elliptical, racetrack-shaped, irregular, etc. Irregular shape refers to other shapes besides those listed above.

[0119] For example, the first length dimension of the housing 101 can be 170mm to 200mm (including the endpoint values), such as 170mm, 180mm, 185mm, 190mm, 200mm, etc., and the second length dimension of the housing 101 (for a cylindrical housing 101, the second length dimension is equivalent to the diameter of the cross section perpendicular to the first direction) can be 45mm to 60mm (including the endpoint values), such as 45mm, 48mm, 50mm, 53mm, 55mm, 58mm, 60mm, etc.

[0120] Please see Figure 1 , Figure 5 , Figure 15 and Figure 22 For a conference device with a power supply component 104, preferably, the power supply component 104 and the circuit board 105 can be located on the same side of the speaker 102 along the first direction, and the circuit board 105 can be located on one side of the power supply component 104 along the second direction, so that the power supply component 104 and the circuit board 105 can be arranged in the elongated housing 101.

[0121] Compared with the flat-shaped conference equipment in related technologies, the elongated conference equipment in this embodiment has a compact structure, which is not only easy to pick up, but also easy to store in a relatively small storage space such as a backpack's storage bag, thereby improving the portability of the conference equipment.

[0122] Please continue reading. Figures 13 to 15 , Figure 24 A third opening 101d can be provided on the housing 1011 to avoid obstructing the microphone 103. For conferencing equipment with multiple microphones 103, please refer to [link to relevant documentation]. Figures 13 to 15 , Figure 24Multiple third openings 101d can be provided along the circumference of the shell 1011. The multiple third openings 101d are spaced apart along the circumference of the shell 1011. At least a portion of the multiple microphones 103 are respectively provided at the corresponding third openings 101d.

[0123] In other words, the number of third openings 101d arranged circumferentially along the shell 1011 can be equal to or less than the number of microphones 103. When the number of third openings 101d arranged circumferentially along the shell 1011 is equal to the number of microphones 103, the third openings 101d correspond one-to-one with the microphones 103, and each microphone 103 is respectively set at the corresponding third opening 101d. When the number of third openings 101d arranged circumferentially along the shell 1011 is less than the number of microphones 103, the shell 101 can be provided with third openings 101d in other parts besides the circumferential direction of the shell 1011. Some microphones 103 are respectively set at the corresponding third openings 101d in the circumferential direction of the shell 1011, and other microphones 103 (at least one microphone 103) are set at the third openings 101d in other parts.

[0124] For example, please refer to Figure 13 and Figure 15 The conference equipment may include a mounting bracket 125 with a third opening 101d. The number of third openings 101d may be one or more. The mounting bracket 125 is disposed on one side of the housing 1011 along a first direction. Preferably, the mounting bracket 125 is located above a plurality of third openings 101d spaced circumferentially along the housing 1011, meaning the third openings 101d of the mounting bracket 125 are located at the top of the housing 1011. Microphones 103 may be respectively disposed at each of the third openings 101d of the mounting bracket 125; that is, other microphones 103 may be disposed at the third openings 101d on the mounting bracket 125.

[0125] In other embodiments, the shell 1011 may have a folded edge with a third opening 101d on one side along the first direction. More preferably, the folded edge may be located above a plurality of third openings 101d spaced circumferentially along the shell 1011, which means that the third openings 101d of the folded edge are located at the top of the shell 1011. The number of third openings 101d on the folded edge may be one or more, and a microphone 103 may be respectively provided at each of the third openings 101d on the folded edge. That is, other microphones 103 may be provided at the third openings 101d on the folded edge.

[0126] The purpose of providing multiple third openings 101d at intervals along the circumference of the housing 1011 is to enable the microphone 103 to be arranged along the circumference of the housing 1011. When the conference equipment is placed on a support surface such as a table, one side of the housing 1011 along the first direction can face the support surface such as the table, so that the microphone 103 can pick up sound from multiple directions along the circumference of the housing 1011.

[0127] In addition, in related technologies, the microphones of flat conference equipment can only be set along the circumference of the conference equipment, and the microphones can only pick up sound in the circumference of the conference equipment.

[0128] Regarding the conference equipment in this application, by setting the housing 101 into a long strip shape, structures such as the fixing bracket 125 and folded edges can be used to position some microphones 103 in locations other than the circumference of the housing 1011, thereby enabling sound pickup from more directions. For example, for Figure 13 and Figure 15 The conference equipment shown has a mounting bracket 125 or a folded edge as described above. When the conference equipment is placed on a support surface such as a desktop, the side of the housing 1011 that is away from the mounting bracket 125 or the folded edge along the first direction can face the support surface such as the desktop (i.e., the mounting bracket 125 or the folded edge is located above a plurality of third openings 101d that are spaced apart circumferentially along the housing 1011). This is equivalent to the microphone 103 at the mounting bracket 125 or the folded edge being located at the top of the conference equipment. This allows the microphone 103 at the mounting bracket 125 or the folded edge to cooperate with the microphone 103 circumferentially located on the housing 1011, enabling the microphone 103 to pick up sound at the pitch angle.

[0129] In addition, for conference equipment with lifting mechanism 113, the lifting height of lifting mechanism 113 can be set to make the microphone 103 located on the top of the conference equipment higher than the height of the laptop screen when in use, or the lifting height of lifting mechanism 113 can be automatically adjusted according to the direction of the speaker's sound source, so that the sound of the conference equipment is not blocked, and better sound can be recorded during the meeting.

[0130] Please see Figure 15 and Figure 24 The conference equipment can be equipped with a first flexible circuit board 116. The microphone 103 corresponding to the third opening 101d on the housing 1011 can be electrically connected to the circuit board 105 through the same first flexible circuit board 116. This means that each microphone 103 is connected as one unit through the same first flexible circuit board 116. The microphone 103 corresponding to the third opening 101d on the housing 1011 can also be electrically connected to the circuit board 105 through different first flexible circuit boards 116. This means that there are at least two first flexible circuit boards 116, and each first flexible circuit board 116 is electrically connected to at least one microphone 103.

[0131] For example, the conference equipment may be configured with a control board for the microphone 103, which is electrically connected to the first flexible circuit board 116 and the main circuit board 105 respectively.

[0132] Further, please refer to Figure 15 and Figure 24 Each microphone 103 corresponding to the third opening 101d can be sealed with the housing 1011. That is to say, at least the part of the microphone 103 that receives sound is located in a relatively sealed space, which is only connected to the third opening 101d, thereby greatly reducing the influence of other directions of sound on each microphone 103 during the sound reception process.

[0133] It should be noted that if there is only one third opening 101d in the circumferential direction of the housing 1011, the microphone 103 can also be sealed with the housing 1011.

[0134] Figure 15 , Figures 24 to 26 The conference equipment shown is provided with a sealing structure 117, which surrounds the microphone 103. That is, the entire microphone 103 is located in a relatively sealed space enclosed by the sealing structure 117. In other embodiments, the sealing structure 117 may only surround the outer periphery of the microphone 103's sound-receiving part and make sealed contact with the housing 1011, which means that the sealing structure 117 may also make sealed contact with the microphone 103.

[0135] The sealing structure 117 mainly utilizes its own elastic deformation to achieve sealing. The material of the sealing structure 117 can be one or a combination of rubber (including natural rubber and synthetic rubber, among which synthetic rubber includes nitrile rubber, butene rubber, silicone rubber and chloroprene rubber, etc.), polyurethane, fluororubber, silicone, shock-absorbing plastics, etc.

[0136] In other embodiments, a sealing fit can also be achieved by using sealing elements such as foam. However, for a microphone 103 located circumferentially around the housing 1011, the microphone 103 is generally moved from one side of the corresponding third opening 101 along the first direction to the corresponding third opening 101d. For example, for a microphone 103 mounted on a mounting bracket 106, the mounting bracket 106 can be inserted into the receiving cavity 101a from one end of the housing 1011 along the first direction, and the microphone 103 can be moved to the corresponding third opening 101d by moving the mounting bracket 106 along the first direction within the receiving cavity 101a. However, this mounting method is prone to causing the foam to be pulled and damaged, while the sealing structure 117 has good elastic deformation capability and is not easily damaged by pulling. Therefore, it is preferable to use the sealing structure 117 for sealing.

[0137] The specific structure of the sealing structure 117 is not limited; for example, please refer to [link to relevant documentation]. Figures 24 to 26 The sealing structure 117 may include a sealing body 1171 and a first annular rib 1172 and a second annular rib 1173 disposed on the same side of the sealing body 1171. The second annular rib 1173 surrounds the outer periphery of the first annular rib 1172. The sealing body 1171 may be mounted on a structure such as a mounting bracket 106. The sealing body 1171 may also be in sealing contact with the structure such as the mounting bracket 106. The sealing body 1171 may also be fixed to the microphone 103 by means of adhesive bonding or other methods. The first annular rib 1172 and the second annular rib 1173 are both in sealing contact with the shell 1011.

[0138] In other words, at least two layers of sealing can be achieved through the first annular rib 1172 and the second annular rib 1173, thereby improving the sealing performance of the sealing structure 117.

[0139] Further, please refer to Figure 26 The height of the second annular rib 1173 protruding from the sealing body 1171 can be lower than the height of the first annular rib 1172 protruding from the sealing body 1171, thereby better preventing the second annular rib 1173 from failing to seal due to excessive deformation.

[0140] In other embodiments, the sealing body 1171 may be in sealed contact with the housing 1011, and the first annular rib 1172 and the second annular rib 1173 may be sealed around the outer periphery of the microphone 103 or the sound receiving part of the microphone 103.

[0141] In other embodiments, the sealing structure 117 may also have only one annular rib.

[0142] In other embodiments, microphones 103 located in other positions, such as those corresponding to the third opening 101d on the mounting bracket 125 or the housing 1011, may also be sealed to the mounting bracket 125 or the housing 1011.

[0143] For conferencing equipment with base 107, preferably, please refer to... Figure 3 The base 107 can be located on one side of the housing 101 along the first direction, that is, the housing 101 is placed vertically on the base 107.

[0144] Figure 3 The base 107 is located on the side of the housing 101 along the first direction close to the speaker 102. Since the speaker 102 generally has a large volume, the base 107 is located on the side of the housing 101 along the first direction close to the speaker 102, so that the speaker 102 can be as close as possible to the table or other supporting surface, thereby reducing the shaking of the speaker 102 and making the conference equipment more stable.

[0145] In other embodiments, the base 107 may also be located on the side of the housing 101 away from the speaker 102 along the first direction.

[0146] For conference equipment with a lifting mechanism 113, to facilitate the arrangement of the lifting mechanism 113, please refer to [reference needed]. Figure 5 The speaker 102, power supply component 104 and circuit board 105 can be located on the same side of the lifting mechanism 113 along the second direction.

[0147] Please continue reading. Figure 13 and Figure 15 The housing 101 may include a first cover 1012, which is disposed on one end of the housing 1011 along a first direction. The power supply component 104 and the circuit board 105 are located between the first cover 1012 and the speaker 102. That is, the first cover 1012 is located on the side of the power supply component 104 and the circuit board 105 away from the speaker 102 along the first direction.

[0148] To facilitate the assembly and disassembly of the conference equipment, the first cover 1012 can be detachably connected to the housing 1011, for example, see [reference needed]. Figure 23 The first cover 1012 can be equipped with a snap fastener 10121, and the first cover 1012 is snapped into the body 1011 through the snap fastener 10121.

[0149] In other embodiments, the first cover 1012 may also form an integral, non-removable structure with the body 1011.

[0150] Please see Figure 14 The housing 101 may also include a protective plate 1013, which covers the end of the housing 1011 opposite to the first cover 1012 along the first direction. That is, the protective plate 1013 is located on the side of the speaker 102 away from the power supply assembly 104 and the circuit board 105 along the first direction.

[0151] The materials of the protective plate 1013 include, but are not limited to, rubber and silicone.

[0152] The protective plate 1013 can be non-detachably connected to the shell 1011, or the protective plate 1013 can be detachably connected to the shell 1011.

[0153] Please see Figure 14 The housing 101 can be provided on the protective plate 1013 to avoid the first opening 101b of the diaphragm 1022 of the speaker 102.

[0154] For conference equipment with sensor 122, the first opening 101b on the protective plate 1013 can also be used to avoid sensor 122.

[0155] In some embodiments, the protective plate 1013 may also be provided with a third opening 101d to avoid the microphone 103. The third opening 101d may be provided in the same or similar manner as the first cover 1012. The microphone 103 may also be sealed with the protective plate 1013. This will not be described in detail here.

[0156] For conference equipment without a base 107, when placing the equipment, the protective plate 1013 can face the table or other supporting surface, with the first cover 1012 located above the protective plate 1013; alternatively, the first cover 1012 can face the table or other supporting surface, with the protective plate 1013 located above the first cover 1012. These two placement methods are equivalent to placing the conference equipment vertically. In addition, the conference equipment can also be placed horizontally, meaning the housing 1011 can face the table or other supporting surface.

[0157] For a conference device with a base 107, if the base 107 is located on one side of the housing 101 along the first direction, the base 107 can be as follows: Figure 14 As shown, the base 107 is located on the side of the housing 1011 near the protective plate 1013. In other embodiments, the base 107 may also be located on the side of the housing 1011 near the first cover 1012.

[0158] Please continue reading. Figure 13 For the first cover 1012 placed on the upper side of the protective plate 1013, a storage slot 1012b can be provided on the side of the first cover 1012 away from the receiving cavity 101a. The storage slot 1012b can be used to place items such as adapters and signal receivers.

[0159] In some other embodiments, the housing 101 may also be placed horizontally on the base 107, that is, the body 1011 of the housing 101 faces the base 107.

[0160] To facilitate the storage of conference equipment, the housing 101 and the base 107 can be detachably connected, meaning that the housing 101 and the base 107 can be separated and stored separately.

[0161] It should be noted that the housing 101 is not limited to having a first cover 1012 and / or a protective plate 1013. For example, the housing 101 may have a second cover instead of a protective plate 1013. Alternatively, the first cover 1012 and / or the protective plate 1013 may be replaced by other structures of the conference equipment. For example, the base 107 may be used instead of the first cover 1012 or the protective plate 1013. Alternatively, the end of the housing 1011 closest to the speaker 102 along the first direction (i.e., the end where the protective plate 1013 was originally installed) may be directly open to serve as a first opening 101b to avoid the diaphragm 1022 of the speaker 102.

[0162] In some embodiments, please refer to Figure 5 , Figure 6 , Figure 15 and Figure 22 The conference equipment can also have a light-emitting component 109 installed within the housing cavity 101a. The light-emitting component 109 is electrically connected to the circuit board 105. The light-emitting component 109 is used to emit light of at least one color for a decorative effect.

[0163] The specific structural form of the light-emitting component 109 is not limited; for example, please refer to [link to relevant documentation]. Figure 15 and Figure 22 The light-emitting component 109 may include an LED bead 1091 and a light guide 1092. The LED bead 1091 may be directly mounted on the circuit board 105, or it may be electrically connected to the circuit board 105 via flexible connectors such as wires or flexible circuit boards. One end of the light guide 1092 faces the LED bead 1091, and the other end faces the housing 101, so as to guide the light emitted by the LED bead 1091.

[0164] Figure 15 and Figure 22 The conference equipment shown has a decorative element 110 on the housing 101. The other end of the light guide 1092 faces the decorative element 110. The light emitted by the lamp bead 1091 is projected onto the decorative element 110 through the light guide 1092, which can achieve a better aesthetic effect.

[0165] In some other embodiments, the decorative element 110 may not be provided on the housing 101. For example, some parts of the housing 101 may be made of light-transmitting material, and the other end of the light guide 1092 may face the light-transmitting plate or the part of the housing 101 that is made of light-transmitting material.

[0166] For the elongated shell 101, please refer to... Figure 5 and Figure 6 The light-emitting component 109, the power supply component 104, and the circuit board 105 can be located on the same side of the speaker 102 along the first direction, so that the space within the receiving cavity 101a can be fully utilized to arrange the light-emitting component 109.

[0167] More preferably, the light-emitting component 109 can be located on the side of the circuit board 105 opposite to the power supply component 104 along the second direction.

[0168] Please see Figure 15 The decorative element 110 can be set on the shell 1011.

[0169] In other embodiments, parts of the housing 1011 may be made of a light-transmitting material.

[0170] Additionally, please see Figure 15 The portion of the decorative element 110 or the housing 101 that uses a light-transmitting material can extend between the two opposite ends of the housing 101 along the first direction. For example, the portion of the decorative element 110 or the housing 101 that uses a light-transmitting material can be parallel to the first direction or inclined relative to the first direction. The portion of the decorative element 110 or the housing 101 that uses a light-transmitting material is generally elongated, so that after the light is projected onto the portion of the decorative element 110 or the housing 101 that uses a light-transmitting material through the light guide 1092, a more beautiful visual effect can be presented.

[0171] In other embodiments, for conference equipment with base 107, the light-emitting component 109 may also be disposed on base 107.

[0172] In some embodiments, please refer to Figures 6 to 8 , Figure 30 The conference equipment can also be equipped with an interface component 111, which is electrically connected to the main circuit board 105. The interface component 111 is used to connect external devices 126 (such as pan-tilt cameras, external charging accessories, external microphones, etc.).

[0173] For example, Figure 30 The external device 126 shown is a pan-tilt camera with video capture function. For ease of shooting, the pan-tilt camera is preferably set on the top of the housing 101.

[0174] For the elongated housing 101, the opposite ends of the housing 101 along the first direction can be the top and bottom of the housing 101, respectively. More preferably, the speaker 102 can be located at the bottom of the housing 101.

[0175] In some embodiments, after the gimbal camera is connected to the interface component 111, it can rotate relative to the interface component to capture content at least 360° in the horizontal direction.

[0176] In some embodiments, the gimbal camera can also capture content at least 360° vertically.

[0177] In some embodiments, the gimbal camera can be a single-axis gimbal, a dual-axis gimbal, or a three-axis gimbal, which can track the speaker based on the speaker's position, continuously capturing the speaker's viewpoint and picking up the speaker's audio data.

[0178] Setting up a pan-tilt camera enables video capture capabilities in conference equipment, allowing users to capture video directly from the equipment without needing to configure separate video devices. This reduces user costs and increases user satisfaction with the conference equipment.

[0179] The type of interface component 111 is not limited. For example, interface component 111 can be a pogo pin interface component, a Type-C interface component, a USB interface component, a MiniUSB interface component, a Micro USB interface component, etc.

[0180] The interface component 111 can be disposed on the housing 101, and the external device 126 can be detachably connected to the housing 101, or it can be an integrated design that cannot be separated from the housing 126.

[0181] For detachable external devices 126, please refer to Figures 6 to 8 The interface component 111 can be disposed within the receiving cavity 101a. The housing 101 can be provided with a removable cover. After the cover is opened, the interface component 111 is exposed, and the external device 126 is connected to the exposed interface component 111.

[0182] In other embodiments, the housing 101 may have an opening, and the interface assembly 111 may be disposed at the opening. The interface assembly 111 may be entirely located within the receiving cavity 101a, with only the portion connecting to the external device 126 facing the opening. Alternatively, the interface assembly 111 may be partially located within the receiving cavity 101a, with the portion connecting to the external device 126 extending from the opening to the outside of the housing 101.

[0183] by Figure 5 Taking the conference equipment shown as an example, the interface component 111 can be set on the side of the power supply component 104 away from the speaker 102 along the first direction, which is equivalent to the external device 126 being connected to the side of the power supply component 104 away from the speaker 102 along the first direction.

[0184] Please see Figure 5 and Figure 30 The interface component 111 can be located at or near the top of the conference equipment, which is equivalent to the external device 126 being located at the top of the housing 101.

[0185] Taking an external device 126 as a pan-tilt camera or an external microphone as an example, for a conference device with a lifting mechanism 113, the lifting height of the lifting mechanism 113 can be set to allow the pan-tilt camera or external microphone to be higher than the height of the laptop screen when in use, so that the shooting and sound recording of the conference device are not obstructed, making it easier to shoot and record sound during the meeting.

[0186] Figure 13 The first cover 1012 shown is detachably connected to the housing 1011. When the first cover 1012 is opened, the interface assembly 111 is exposed so that the interface assembly 111 can be connected to the external device 126.

[0187] In other embodiments, an opening may be provided on the first cover 1012 or the body 1011, and the interface component 111 may be disposed at the opening. For the scheme of providing an opening on the first cover 1012, the first cover 1012 may be detachably connected to the body 1011 or may be non-detachably connected to the body 1011.

[0188] In some embodiments, please refer to Figure 7 The conference equipment can be provided with a first magnetic 124 on the housing 101 and a second magnetic 126 on the external device. The first magnetic 124 and the second magnetic 126 are magnetically attracted to each other, that is, the external device 126 can be fixed to the housing 101 by magnetic attraction.

[0189] Both the first magnetic accumulator 124 and the second magnetic accumulator can be magnets. When both the first magnetic accumulator 124 and the second magnetic accumulator are magnets, their magnetic poles are arranged opposite each other. For example, the N pole of the first magnetic accumulator 124 corresponds to the S pole of the second magnetic accumulator, and the S pole of the first magnetic accumulator 124 corresponds to the N pole of the second magnetic accumulator, so as to prevent reverse installation.

[0190] In other embodiments, one of the first magnetic element 124 and the second magnetic element may be a magnet, and the other may be a metal part that can magnetically engage with the magnet.

[0191] For an external device 126 where the interface component 111 is located inside the receiving cavity 101a and the cover needs to be opened to connect the interface component 111 to the external device 126, the first magnetic member 124 can be located inside the receiving cavity 101a.

[0192] For a conference device with a fixed frame 125, the first magnetic component 124 can be mounted on the fixed frame 125. For a conference device without a fixed frame 125 but with a mounting bracket 106, the first magnetic component 124 can be mounted on the mounting bracket 106. In addition, the conference device can also be equipped with other support components to support the first magnetic component 124.

[0193] For a conference device in which the housing 101 has an opening for avoiding the interface assembly 111, the first magnetic suction member 124 can be disposed on the outside of the housing 101 or on the inside of the housing 101. The first magnetic suction member 124 disposed on the outside of the housing 101 is generally disposed directly on the housing 101. The first magnetic suction member 124 disposed on the inside of the housing 101 can be disposed directly on the housing 101 or not disposed on the housing 101. If it is not disposed on the housing 101, the first magnetic suction member 124 can contact the housing 101 or form a certain gap with the housing 101.

[0194] For the first magnetic suction member 124 which is located inside the housing 101 and is not located on the housing 101, the first magnetic suction member 124 can also be located on the fixing frame 125, the mounting bracket 106 or other support members.

[0195] Compared with setting it on the outside of the housing 101, setting the first magnetic member 124 on the inside of the housing 101 can provide better protection and concealment for the first magnetic member 124. Therefore, the first magnetic member 124 is preferably set on the inside of the housing 101.

[0196] The number of the first magnetic element 124 can be one or at least two.

[0197] When there is only one first magnetic member 124, the first magnetic member 124 can be provided only on one side of the interface component 111, or the first magnetic member 124 can extend along the outer periphery of the interface component 111 to be located at least on the two adjacent sides of the interface component 111. For example, the first magnetic member 124 can be arc-shaped, ring-shaped, etc.

[0198] When the number of first magnetic members 124 is at least two, the first magnetic members 124 can be provided on only one side of the interface assembly 111, or they can be provided on multiple sides of the interface assembly 111, for example... Figure 7 The interface component 111 shown is provided with first magnetic 124 on opposite sides. In other embodiments, the first magnetic 124 may be provided on adjacent sides of the interface component 111, or the first magnetic 124 may be provided on at least any three sides of the interface component 111.

[0199] Since the first magnetic clasp 124 and the second magnetic clasp can be automatically aligned through magnetic attraction, the user only needs to bring the second magnetic clasp on the external device 126 close to the first magnetic clasp 124 on the housing 101, and the external device 126 can be automatically installed on the housing 101. When it is necessary to remove the external device 126, only a little external force needs to be applied to the external device 126 to separate it from the housing 101. Compared with the connection methods in related technologies, the magnetic connection method adopted in this embodiment can facilitate the installation and removal of the external device 126.

[0200] Furthermore, for Figure 13 The first cover 1012 shown is detachably connected to the body 1011. After the first cover 1012 is opened, the conference equipment of the interface assembly 111 is exposed. The conference equipment can also be provided with a third magnetic member (not shown in the figure) on the first cover 1012. When the first cover 1012 is placed on the body 1011, the third magnetic member and the first magnetic member 124 are magnetically attracted to each other.

[0201] For the first cover 1012 with the third magnetic component, the first cover 1012 does not need to be equipped with a buckle 10121 or other structure that connects to the body 1011. In other words, the detachable connection between the first cover 1012 and the body 1011 can be achieved simply by the magnetic attraction between the third magnetic component and the first magnetic component 124.

[0202] In other embodiments, the first cover 1012 may also retain a structure such as a buckle 10121 that is connected to the body 1011, which means that the connection of the buckle 10121 and the magnetic attraction can be combined, thereby improving the stability of the connection between the first cover 1012 and the body 1011.

[0203] Please continue reading. Figure 23 The first cover 1012 can be provided with a mounting groove 1012a on the side near the receiving cavity 101a. The third magnetic component can be installed in the mounting groove 1012a, which can both facilitate the fixing of the third magnetic component and limit the position of the third magnetic component.

[0204] For example, please continue reading Figure 23 The first cover 1012 may include a cover body 10122 and a mounting seat 10123 protruding from the cover body 10122, and a mounting groove 1012a is disposed on the mounting seat 10123.

[0205] The specific structure of the mounting base 10123 is not limited; for example, please refer to [link to example]. Figure 23 The mounting base 10123 may have a perimeter 10123a, which surrounds the mounting groove 1012a.

[0206] Please continue reading. Figure 23The mounting base 10123 can also be provided with reinforcing ribs inside the perimeter 10123a. The reinforcing ribs can not only improve the structural strength of the mounting base 10123, but also prevent the first shell cover 1012 from shrinking and deforming.

[0207] For example, please refer to Figure 23 The reinforcing rib may include a first reinforcing rib 10123b connected to the perimeter 10123a. The number of first reinforcing ribs 10123b may be one or more. The first reinforcing rib 10123b may or may not be connected to the cover body 10122.

[0208] For further information, please refer to [link / reference]. Figure 23 The reinforcing rib may also include a second reinforcing rib 10123c connected to the first reinforcing rib 10123b. The number of second reinforcing ribs 10123c may be one or more. The second reinforcing rib 10123c cooperates with the first reinforcing rib 10123b to better improve the structural strength of the mounting base 10123 and prevent the first shell cover 1012 from shrinking and deforming.

[0209] In some other embodiments, the first cover 1012 may not be provided with a mounting base 10123. For example, a portion of the wall surface of the first cover 1012 near the receiving cavity 101a may be recessed to form a mounting groove 1012a.

[0210] In other embodiments, for a conference device having a base 107, the interface component 111 may also be disposed on the base 107, and correspondingly, the first magnetic member 124 is also disposed on the base 107.

[0211] In some embodiments, please refer to Figure 13 , Figure 20 and Figure 21 The conference equipment can also be equipped with a display component 112, which is electrically connected to the main circuit board 105. The display component 112 includes, but is not limited to, displaying information (such as interactive information, power information of the power supply component 104, etc.) and setting touch keys, thereby improving the intelligence of the conference equipment.

[0212] Please see Figure 13 , Figure 20 and Figure 21 For a conference device with a base 107, the base 107 is at least partially disposed outside the housing 101, and the display component 112 may be disposed on the base 107.

[0213] Please see Figure 21The display component 112 includes a screen 1121 and a screen control board 1122. The screen 1121 and the screen control board 1122 can be an integral structure or a separate structure. An integral structure means that the screen 1121 and the screen control board 1122 are directly manufactured into an inseparable whole. A separate structure means that the screen 1121 and the screen control board 1122 are two independent components, which are assembled into a whole.

[0214] The screen 1121 is a component of the display assembly 112 used to display images, and the screen control board 1122 is an internal component of the display assembly 112 that implements image display.

[0215] The type of screen 1121 is not limited. For example, it can be an LCD (Liquid Crystal Display) screen, an LED (Light Emitting Diode) screen, a QLED (Quantum Dot Light Emitting Diodes) screen, a Micro LED (Micro Light Emitting Diodes) screen, a QD-OLED (Quantum Dot OLED) screen, etc.

[0216] In addition, other components (such as function buttons 114 and connection interfaces 115) located on the base 107 can also be electrically connected to the screen control board 1122 so that the screen control board 1122 can act as a relay for other components on the base 107.

[0217] Please see Figure 13 , Figure 20 and Figure 21 To facilitate the placement of the screen 1121, the screen 1121 can be set on the upper surface 107a of the base 107.

[0218] Without affecting other structures, the screen 1121 can cover the upper surface 107a of the base 107 as much as possible to achieve the effect of a large screen.

[0219] Please continue reading. Figure 13 and Figure 20 For conference equipment equipped with a lifting mechanism 113 or a base 107 connected to the housing 101 via a support structure, preferably, the installation position of the lifting mechanism 113 or the support structure on the base 107 is ( Figure 20The location indicated by reference numeral Z in the attached diagram is the installation position. It can be as close as possible to the edge of the base 107. For example, the lifting mechanism 113 or the support structure can be located inside the upper surface 107a of the base 107, and close to the edge of the upper surface 107a (i.e.,...). Figure 20 (As shown in the configuration), the display component 112 or the screen 1121 of the display component 112 can form a recess, which is equivalent to the display component 112 or the screen 1121 being irregularly shaped to adapt to the installation of the lifting mechanism 113 or the support structure. For example, the screen 1121 can be as follows: Figure 20 The partial recessed circular shape shown can be used to display either a partial area of ​​the irregularly shaped screen 1121 or the entire irregularly shaped area. Alternatively, the lifting mechanism 113 or the support structure can be located outside the upper surface 107a and close to the side of the base 107, so that the upper surface 107a of the base 107 can have as large an area as possible to accommodate the screen 1121.

[0220] Additionally, please see Figure 4 For a conference setup with a lifting mechanism 113, where the housing 101 can be roughly integrated with the base 107 under the drive of the lifting mechanism 113, the screen 1121 can be placed on the upper surface 107a of the base 107. When the housing 101 is lowered to the second preset position, the screen 1121 can be covered by the housing 101, thus providing a certain degree of protection for the screen 1121.

[0221] In other embodiments, the screen 1121 may also be disposed in other parts of the base 107, for example, the screen 1121 may also be disposed on the side surface of the base 107.

[0222] Please continue reading. Figure 21The screen 1121 includes a main body 1121a and a connecting portion 1121b located on the outer periphery of the main body 1121a. The main body 1121a is the part of the screen 1121 used to display images, and the connecting portion 1121b is the part that connects the screen 1121 to the base 107. The base 107 has an inner cavity 107b and a mounting opening communicating with the inner cavity 107b. Preferably, the main body 1121a can be exposed at the mounting opening, while the connecting portion 1121b is located in the inner cavity 107b, and the surface of the connecting portion 1121b near the housing 101 faces the inner wall surface of the base 107 located on the periphery of the mounting opening. The connecting portion 1121b can be connected to the inner wall surface of the base 107 by means of adhesive bonding or the like. In other words, the inner wall can cover at least part of the connecting part 1121b to reduce the visual black border formed by the connecting part 1121b at the edge of the entire screen 1121. The main body 1121a of the screen 1121 can be seen from the outside, while only a small part of the black border can be seen, or even the black border can be almost not seen, thereby making the appearance of the base 107 more beautiful.

[0223] Please see Figure 21 The main body 1121a can protrude from the connecting part 1121b. The main body 1121a is inserted into the mounting opening, which means that the main body 1121a can be positioned through the mounting opening, thereby improving the convenience of installing the screen 1121.

[0224] In some other embodiments, the main body 1121a may not protrude from the connecting part 1121b.

[0225] In other embodiments, for the display assembly 112 where the screen 1121 and the screen control board 1122 are an integral structure, the screen control board 1122 may have a protruding edge located on the outer periphery of the screen 1121. The screen 1121 is exposed at the mounting opening, while the protruding edge is located in the inner cavity 107b, and the surface of the protruding edge near the housing 101 faces the inner wall surface of the base 107 located on the periphery of the mounting opening. The protruding edge can be connected to the inner wall surface of the base 107 by means of adhesive bonding or the like.

[0226] The screen 1121 and the protruding edge may or may not be located on the same plane. When the screen 1121 and the protruding edge are not located on the same plane, the screen 1121 is located in the mounting opening.

[0227] Please see Figure 21 The base 107 can be provided with an auxiliary bracket 1073 in the inner cavity 107b. The auxiliary bracket 1073 is used to support the display component 112, thereby improving the stability of the installation of the display component 112.

[0228] Please continue reading. Figure 21A buffer 1074 can be sandwiched between the display component 112 and the auxiliary support 1073. The buffer 1074 can be foam, rubber pad, silicone pad, etc. The buffer 1074 is used to separate the auxiliary support 1073 from the display component 112 to avoid the auxiliary support 1073 directly contacting the display component 112 and damaging the display component 112.

[0229] Further, please refer to Figure 21 The base 107 may include a first cover 1071 and a second cover 1072 having a mounting opening. The second cover 1072 is located on the side of the first cover 1071 near the housing 101 and together with the first cover 1071, forms an inner cavity 107b. The second cover 1072 may be detachably connected to the first cover 1071 to facilitate the installation and removal of the display assembly 112.

[0230] In some other embodiments, the display component 112 may also be disposed on the housing 101. For a housing 101 that is elongated, in order to facilitate the placement of the display component 112, the display component 112 may be disposed at the upper end of the housing 101.

[0231] The screen 1121 can be disposed on the housing 1011 or on the first cover 1012. To achieve the effect of the screen 1121 having no connecting portion 1121b, the housing 1011 can have a mounting opening, with the main body 1121a of the screen 1121 exposed at the mounting opening, and the connecting portion 1121b located in the receiving cavity 101a, facing the inner wall surface of the housing 1011 located around the mounting opening. Alternatively, the first cover 1012 can have a mounting opening, with the main body 1121a of the screen 1121 exposed at the mounting opening, and the connecting portion 1121b located in the receiving cavity 101a, facing the inner wall surface of the first cover 1012 located around the mounting opening.

[0232] Please see Figures 15 to 17 The conference equipment can also be equipped with a second flexible circuit board 118, and the display component 112 and other components (such as function buttons 114 and connection interfaces 115) set on the base 107 can be electrically connected to the main circuit board 105 through the second flexible circuit board 118.

[0233] For conference equipment with a connection interface 115 on the base 107, there can be two second flexible circuit boards 118. One second flexible circuit board 118 is used to realize charging or data transmission (such as meeting minutes, recording, and other audio data) of the connection interface 115, and the other second flexible circuit board 118 is used to transmit control data of the display component 112. In addition, for conference equipment with function buttons 114 on the base 107, the second flexible circuit board 118 used to transmit control data of the display component 112 can also be used to transmit control data of the function buttons 114.

[0234] For the connection method of other components (such as function buttons 114 and connection interfaces 115) set on the base 107 and the screen control board 1122, both second flexible circuit boards 118 can be electrically connected to the screen control board 1122 of the display component 112.

[0235] For conference equipment equipped with a lifting mechanism 113, please refer to [link / reference]. Figures 15 to 17 The second flexible circuit board 118 can be set to a relatively long length in the lifting direction of the lifting mechanism 113, so that a part of the second flexible circuit board 118 can extend as the housing 101 rises and curl as the housing 101 falls, thereby better preventing the second flexible circuit board 118 from being damaged by pulling or squeezing during the lifting process of the housing 101.

[0236] If the number of second flexible circuit boards 118 is greater than one, such as the scheme described in the previous embodiment where two second flexible circuit boards 118 can be set, all the second flexible circuit boards 118 can be stacked together to stretch or curl together.

[0237] Please see Figure 16 and Figure 17 The second flexible circuit board 118 has a stretchable or rollable portion 118c. For conference equipment with a mounting bracket 106, the second flexible circuit board 118 can be mounted on the mounting bracket 106. Simultaneously, a receiving space 106a can be provided on the mounting bracket 106, and the stretchable portion 118c is located within the receiving space 106a. That is, the stretchable portion 118c stretches or rolls within the receiving space 106a. This method facilitates the installation of the second flexible circuit board 118 and also effectively avoids interference between the second flexible circuit board 118 and other components or structures during the stretching or rolling process.

[0238] Please see Figure 16 and Figure 17 The second flexible circuit board 118 may also have an extension portion 118d, which extends circumferentially along the housing 1011 and is electrically connected to the circuit board 105, thereby facilitating the electrical connection between the second flexible circuit board 118 and the circuit board 105 within a limited space.

[0239] by Figures 15 to 17Taking the conference equipment shown as an example, along the lifting direction of the lifting mechanism 113, the second flexible circuit board 118 has a first connecting part 118a and a second connecting part 118b spaced apart. The first connecting part 118a is directly or indirectly connected to the slider 11322, and the second connecting part 118b is directly or indirectly connected to the mounting bracket 106. The area of ​​the second flexible circuit board 118 between the first connecting part 118a and the second connecting part 118b is the bending and stretching part 118c.

[0240] Further, please refer to Figure 16 and Figure 17 The second flexible circuit board 118 may further include a first segment 1181 having a first connecting portion 118a and a second segment 1182 having a second connecting portion 118b and a bending portion 118c. The second segment 1182 is located on one side of the first segment 1181 in the lateral direction (intersecting the lifting direction of the lifting mechanism 113 in the lateral direction) and is located within the receiving space 106a. That is, the first segment 1181 and the second segment 1182 are staggered. The second segment 1182 is located on one side of the slider 11322 in the lateral direction and extends along the lifting direction of the lifting mechanism 113. During the lifting and lowering process of the housing 101, the bending portion 118c located in the second segment 1182 extends in the lifting direction as the housing 101 rises or curls in a stacked manner as the housing 101 falls (i.e., a part of the bending portion 118c is located in front of the other part of the bending portion 118c). This structure facilitates the direct or indirect connection between the second flexible circuit board 118 and the slider 11322, and also facilitates the extension and curling of the second flexible circuit board 118.

[0241] Please continue reading. Figure 16 and Figure 17 The second segment 1182 may also have an extension portion 118d that extends circumferentially along the housing 1011 and is electrically connected to the circuit board 105.

[0242] In other embodiments, the second flexible circuit board 118 may also be provided without staggering the first segment 1181 and the second segment 1182.

[0243] In some embodiments, please refer to Figure 9 , Figure 10 , Figure 13 , Figure 14 and Figure 29 The conference equipment can be equipped with a coupled feed antenna 119 inside the housing cavity 101a. Meanwhile, the housing 101 has a feed gap 101e. The coupled feed antenna 119 is spaced apart from the housing 101 and faces the feed gap 101e.

[0244] For ease of installation of the coupled-feed antenna 119, please refer to the example provided. Figure 10The coupled-feed antenna 119 can be mounted on the mounting bracket 106.

[0245] Please continue reading. Figure 10 and Figure 29 The mounting bracket 106 can be configured with a mounting surface that matches the shape of the coupled feed antenna 119, and the coupled feed antenna 119 can be attached to the mounting surface.

[0246] The mounting bracket 106 and the housing 101 can be slidably fitted together. That is, the mounting bracket 106 can slide relative to the housing 101 to be inserted into the receiving cavity 101a of the housing 101. When the mounting bracket 106 slides into place, the coupled feed antenna 119 also moves to a position facing the feed gap 101e, which makes it easy to align the coupled feed antenna 119 with the feed gap 101e.

[0247] The coupled-fed antenna 119 is a Bluetooth antenna that primarily uses coupled-fed technology to transfer energy. Specifically, coupled-fed is a non-contact excitation method. Through the interaction of the electromagnetic field between the feed source (such as a microstrip line, coplanar waveguide, resonator, etc.) of the coupled-fed antenna 119 and the feed slot 101e, energy is indirectly transferred to the feed slot 101e, thereby achieving radiation from the coupled-fed antenna 119.

[0248] The coupled feeding can be equivalent to a mutual inductance coupled circuit. The coupled feeding antenna 119 is equivalent to a primary coil, and the feeding slot 101e is equivalent to a secondary coil. Energy is transferred from the feed source of the coupled feeding antenna 119 to the feeding slot 101e through mutual inductance.

[0249] The main feature of coupled feeding technology is that energy is transferred through electromagnetic fields. There is no electrical connection between the coupled feeding antenna 119 and the housing 101 with the feeding gap 101e. When the coupled feeding antenna 119 is set, there is generally a gap formed by the interval between the coupled feeding antenna 119 and the housing 101.

[0250] The size of the feed gap 101e can be adjusted according to design requirements. For example, if only air exists around the feed gap 101e, the length L of the feed gap 101e can be: 0.45 times the wavelength ≤ L ≤ 0.5 times the wavelength. If other media besides air, such as non-metallic materials like plastic or glass, exist around the feed gap 101e, the length L of the feed gap 101e can be: 0.25 times the wavelength ≤ L ≤ 0.5 times the wavelength due to its dielectric constant.

[0251] For example, the width W of the feed gap 101e can be: W≤0.05 times the wavelength (i.e. 1 / 20 of the wavelength).

[0252] The distance between the coupled feed antenna 119 and the feed slot 101e can also be adjusted according to design requirements. For example, the distance D between the coupled feed antenna 119 and the feed slot 101e can be: D≤wavelength / (2*π), that is, D≤0.16 times the wavelength.

[0253] The wavelengths mentioned above are all operating frequency wavelengths.

[0254] In related technologies, Bluetooth antennas in conference equipment typically transmit energy through direct power supply. Specifically, a radio frequency (RF) chip is mounted on the main circuit board, and conductive components such as spring contacts or conductive foam are placed between the main circuit board and a housing with gaps. These components connect the RF chip to the housing by contacting the power supply positions located on either side of the gaps. The RF signal emitted by the RF chip is transmitted through the spring contacts or conductive foam to the gaps in the housing, where it is then radiated. However, during the installation of these components, they need to contact the housing and slide along it to reach the power supply positions. This installation method can easily damage the spring contacts or conductive foam during sliding, leading to a risk of inconsistent and unreliable performance (inconsistency and unreliability refer to performance fluctuations or failures caused by manufacturing or material issues). Furthermore, to ensure conductivity, the power supply positions on the housing require laser engraving or welding of gold-plated spring contacts, which also increases the cost of the conference equipment.

[0255] The coupled-feed antenna 119 in this embodiment of the conference equipment transmits energy through an electromagnetic field. The coupled-feed antenna 119 and the housing 101 do not require electrical connection via conductive components such as springs or conductive foam. Therefore, the consistency and reliability of the conference equipment are not affected by these components. Furthermore, compared to conference equipment in related technologies, the conference equipment in this embodiment reduces costs by eliminating these components. In other words, by incorporating the coupled-feed antenna 119, the conference equipment in this embodiment not only improves consistency and reliability but also reduces costs.

[0256] Furthermore, the coupled-feed antenna 119 can be electrically connected to the circuit board 105 via a flexible connector (such as a cable or flexible circuit board).

[0257] Taking the cable as an example, the cable can be connected to the coupled feed antenna 119 and the circuit board 105 respectively.

[0258] The type of cable is not limited. For example, the flexible connector can be an RF coaxial cable. The RF coaxial cable usually has two pads, an inner core and an outer core. Both pads can be connected to the coupled feed antenna 119 and the RF female connector provided on the circuit board 105. Alternatively, the circuit board 105 may not have an RF female connector, and the two pads can be directly soldered to the circuit board 105.

[0259] Direct power feeding in related technologies requires mounting the RF chip on the circuit board. In order to reduce the energy loss from the RF chip to the gap, the RF chip usually needs to be placed close to the gap. Therefore, the placement of the circuit board is limited by the RF chip.

[0260] The coupled feed antenna 119 can be electrically connected to the circuit board 105 through a flexible connector. Therefore, the setting position of the circuit board 105 will not be affected by the coupled feed antenna 119, which makes it easy to flexibly adjust the setting position of the circuit board 105.

[0261] Please continue reading. Figure 13 For the elongated housing 101, the power supply gap 101e can be provided in the housing body 1011. More preferably, the power supply gap 101e can extend circumferentially along the housing body 1011.

[0262] For a conference device with mounting bracket 106, see, for example, [reference needed]. Figures 13 to 15 The feed gap 101e and the circuit board 105 can be located on opposite sides of the mounting bracket 106 along the second direction, which is equivalent to the coupled feed antenna 119 and the circuit board 105 being respectively set on opposite sides of the mounting bracket 106 along the second direction. The flexible connector can extend circumferentially along the housing 1011 to connect the coupled feed antenna 119 and the RF socket set on the circuit board 105. Alternatively, the flexible connector can also extend circumferentially along the housing 1011 to connect the coupled feed antenna 119 and the circuit board 105.

[0263] In addition, the conference equipment is also equipped with a Wi-Fi antenna, which is a separate module from the coupled feed antenna 119.

[0264] The Wi-Fi antenna and the coupled feed antenna 119 can operate in the same frequency band, for example, they can share the 2.4 GHz band. To avoid interference when the Wi-Fi antenna and the coupled feed antenna 119 operate in the same frequency band, they can adopt a time-division multiplexing operation mode. For example, when the coupled feed antenna 119 uses the 2.4 GHz band, the Wi-Fi antenna stops transmitting, and when the Wi-Fi antenna uses the 2.4 GHz band, the coupled feed antenna 119 stops transmitting. This is equivalent to allocating time slots between the Wi-Fi antenna and the coupled feed antenna 119.

[0265] In other embodiments, the Wi-Fi antenna and the coupled feed antenna 119 may also operate in different frequency bands.

[0266] For the elongated housing 101, preferably, the Wi-Fi antenna and the coupled feed antenna 119 can be respectively disposed on opposite sides of the housing 101 along the first direction. When the conference equipment is placed on a support surface such as a desktop, the Wi-Fi antenna is close to the support surface such as the desktop. For the conference equipment with a base 107, the base 107 is located on the side of the Wi-Fi antenna away from the coupled feed antenna 119 along the first direction.

[0267] There can be one or multiple Wi-Fi antennas.

[0268] The Wi-Fi antenna can be set up independently. For example, it can be glued to end face 101a, or it can be integrated onto the circuit board of other components. For instance, if the conference equipment has a sensor 122, the Wi-Fi antenna can be integrated onto the circuit board corresponding to the sensor 122 (e.g., the circuit board 1221 of the pressure sensor). The Wi-Fi antenna can be set in a loop or other shapes. For conference equipment with a protective pad 123, the Wi-Fi antenna can be set in the protective pad 123. In other embodiments, the Wi-Fi antenna can also be set in other locations, such as on the mounting bracket 106.

[0269] In related technologies, for flat conferencing equipment, the Bluetooth antenna and Wi-Fi antenna are close together. Even if the Bluetooth antenna and Wi-Fi antenna operate in a time-division manner, there is still a risk of mutual interference between them.

[0270] As for the conference equipment in this application, after the housing 101 is set into a long strip shape, the coupled feed antenna 119 and the wifi antenna are respectively set on opposite sides of the housing 101 along the first direction, so that there is a relatively long distance between the coupled feed antenna 119 and the wifi antenna, thereby making the anti-interference effect between the coupled feed antenna 119 and the wifi antenna better.

[0271] Furthermore, the conference equipment described in this application is not limited to using the coupled-feed antenna 119. In some embodiments, the conference equipment can also use other types of Bluetooth antennas. For other types of Bluetooth antennas, by setting the Bluetooth antenna and the Wi-Fi antenna on opposite sides of the housing 101 along the first direction, better anti-interference effect can also be achieved.

[0272] In some embodiments, please refer to Figure 8 , Figure 27 and Figure 28The conference equipment may also include a heat-conducting component 120 and a heat sink 121 having a heat transfer section 121a and a heat dissipation section 121b. The heat-conducting component 120 is in thermal contact with the circuit board 105 and the heat transfer section 121a respectively, and the heat dissipation section 121b is connected to the heat transfer section 121a.

[0273] The heat-conducting component 120 is used to transfer the heat generated by the circuit board 105 to the heat transfer component 121 heat transfer part 121a, and then the heat is transferred from the heat transfer part 121a to the heat dissipation part 121b for heat dissipation. This can effectively reduce the temperature of the circuit board 105 during operation and prevent the circuit board 105 from being damaged due to excessive temperature.

[0274] The material of the heat-conducting component 120 is not limited, as long as it can conduct heat. For example, the main material of the heat-conducting component 120 can be a thermally conductive gel, meaning that the heat-conducting component 120 can be a thermally conductive gel layer sandwiched between the circuit board 105 and the heat transfer part 121a. The main components of the thermally conductive gel include polymers (such as silicone polymers, polyurethane, epoxy resin, etc.) and thermally conductive fillers (such as metal powder, oxide fillers, carbon nanotubes, etc.). These components are mixed through a special process and have a gel-like structure. The thermally conductive gel has excellent thermal conductivity, which can effectively reduce thermal resistance and allow heat to transfer more quickly from the circuit board 105 to the heat transfer part 121a.

[0275] The material of the heat sink 121 is not limited, as long as it can dissipate heat. For example, the main material of the heat sink 121 can be graphite. Graphite has a high thermal conductivity, which can reach 700W / (m·k)-1300W / (m·k). Therefore, the heat sink 121 made of graphite has excellent heat dissipation performance.

[0276] The arrangement of the heat sink 121 within the receiving cavity 101a is not limited. For an elongated housing 101, please refer to [example description]. Figure 8 and Figure 27 The heat dissipation part 121b of the heat dissipation component 121 can be arranged around the inner wall surface of the shell 1011, so that the heat dissipation component 121 can distribute heat more evenly around the shell 1011.

[0277] For conference equipment with power supply component 104, heat dissipation part 121b can also be located on the outer periphery of power supply component 104, so as to dissipate heat from power supply component 104 to a certain extent.

[0278] Furthermore, a heat dissipation gap may exist between at least one of the inner wall surface and the power supply component 104 and the heat dissipation part 121b. That is, a heat dissipation gap may exist between the heat dissipation part 121b and both the inner wall surface and the power supply component 104, and a heat dissipation gap may exist between the heat dissipation part 121b and any one of the inner wall surface and the power supply component 104. Providing a heat dissipation gap can effectively prevent the distance between the inner wall surface and / or the power supply component 104 and the heat dissipation part 121b from being too close, which would affect the heat dissipation effect of the heat dissipation part 121b.

[0279] In addition, when the circuit board 105 is mounted on the mounting bracket 106, and the mounting bracket 106 and the housing 101 are slidably connected, there is a heat dissipation gap between the heat dissipation part 121b and the inner wall surface. This can also better prevent the heat dissipation part 121b from being adversely affected by friction between the heat dissipation part 121b and the inner wall surface when the mounting bracket 106 is fitted into the housing 101, such as deformation of the heat dissipation part 121b, damage to the connection between the heat dissipation part 121b and the circuit board 105, or wear of the heat dissipation part 121b.

[0280] For a conference device having a coupled-feed antenna 119 and a feed gap 101e, the heat dissipation part 121b is preferably located below the gap between the coupled-feed antenna 119 and the feed gap 101e to avoid interference with the antenna function.

[0281] Further, please refer to Figure 27 and Figure 28 For a conference device in which the microphone 103 is arranged circumferentially along the housing 1011, the number of heat dissipation parts 121b can also be two. The two heat dissipation parts 121b are arranged at intervals along the first direction to avoid the microphone 103 and / or avoid the control board of the microphone 103. That is, the microphone 103 is located between the two heat dissipation parts 121b, and the two heat dissipation parts 121b dissipate heat on opposite sides of the microphone 103 along the first direction, thereby achieving a better heat dissipation effect.

[0282] In other embodiments, there may be only one heat dissipation unit 121b, which is located on one side of the microphone 103 along the first direction.
