Technical Field
[0001] This invention belongs to the field of speaker technology, and particularly relates to video camera speakers. Background Technology
[0002] With the improvement of people's living standards and the pursuit of diversified entertainment methods, home karaoke has become a popular leisure activity. To meet this demand, audio equipment integrating display and sound functions has emerged on the market. These devices typically include a main speaker for playing accompaniment music and vocals, and a display screen for displaying lyrics and video images. Users can connect a microphone to sing, achieving an integrated singing experience.
[0003] Microphone storage has always been a problem for users in existing KTV (Karaoke Television) speaker products. To facilitate microphone storage, some speaker products have simple slots or holders on the side or top of the speaker body. However, these storage structures are usually quite open, making microphones susceptible to detachment, loss, or even damage from drops due to external impacts or equipment movement, failing to provide stable and reliable protection. Furthermore, some speakers may use storage cavities with covers, but the opening and closing mechanisms of these covers are flawed. For example, the lack of an effective retaining mechanism when the cover is closed may allow it to accidentally pop open during transport, leaving the microphone unprotected. Summary of the Invention
[0004] The purpose of this application is to provide a video camera speaker, which aims to solve the problems of how to improve the reliability of microphone storage and how to improve the assembly efficiency of the video camera speaker.
[0005] To achieve the above objectives, the technical solution adopted in this application is as follows:
[0006] In a first aspect, a video camera speaker is provided, comprising: a speaker body having a receiving cavity; the speaker body including a first housing and a second housing joined to the first housing, the first housing and the second housing together forming the receiving cavity, a receiving cavity for accommodating a microphone being provided on one side wall of the first housing, the receiving cavity having an opening for the microphone to enter; a speaker disposed in the receiving cavity and connected to the inner wall of the second housing, the speaker being used to play sound; a flip cover rotatably connected to the first housing, the flip cover having a first state of covering the opening and a second state of exposing the opening; and an adsorption assembly including a first magnetic member disposed on the side wall of the first housing and a second magnetic member disposed on the flip cover, the first magnetic member being used to magnetically attract the second magnetic member when the flip cover is in the first state, so that the flip cover is held in the first state.

[0013] In some embodiments, the connector is provided with a threaded hole, and one end of the shaft is threadedly connected to the threaded hole.
[0014] In some embodiments, the shaft member includes a rod portion threadedly connected to the threaded hole and a limiting portion connected to the end of the rod portion away from the connector. The rotating portion is provided with a through hole for the rod portion to pass through. The limiting portion is arranged around the periphery of the rod portion.

[0024] Please see Figures 1 to 12This application provides a video camera speaker, including a speaker body 10 with a receiving cavity 12; the speaker body 10 includes a first shell 16 and a second shell 17 spliced with the first shell 16, the first shell 16 and the second shell 17 together form the receiving cavity 12, one side wall of the first shell 16 has a receiving cavity 11 for receiving a microphone 200, the receiving cavity 11 has an opening 111 for the microphone 200 to enter; a speaker 80 is disposed in the receiving cavity 12 and connected to the inner wall of the second shell 17, the speaker 80 is used to play sound; a flip cover 20 is rotatably connected to the first shell 16, the flip cover 20 has a first state of covering the opening 111 and a second state of exposing the opening 111; and an adsorption assembly 30, including a first magnetic member 31 disposed on the side wall of the first shell 16 and a second magnetic member 32 disposed on the flip cover 20, the first magnetic member 31 is used to magnetically attract the second magnetic member 32 when the flip cover 20 is in the first state, so that the flip cover 20 is kept in the first state.
[0025] The speaker body 10 is a roughly rectangular shell, housing a speaker 80, amplifier circuitry, and power module for sound playback. The speaker body 10 can be made of plastic, metal, or wood. A receiving cavity 11 for accommodating a microphone 200 is formed on one side wall of the first housing 16. The shape of the receiving cavity 11 is adapted to the shape of the microphone 200's main body, for example, it can be a cylindrical recess. The receiving cavity 11 has an opening 111 facing outwards from the side wall, allowing the microphone 200 to be inserted or removed. A flip cover 20 is rotatably connected to the side wall of the first housing 16. When the flip cover 20 is in its first state, its outer surface is flush with the outer contour of the speaker body 10 to maintain the overall integrity of the product's appearance.
[0026] The adsorption assembly 30 provides a holding force to prevent accidental opening of the flip cover 20 when it is in the first state. The adsorption assembly 30 includes a first magnetic element 31 and a second magnetic element 32. The first magnetic element 31 is disposed within the side wall of the first housing 16 and located at the edge of the opening 111 of the receiving cavity 11. The second magnetic element 32 is correspondingly disposed on the flip cover 20. When the flip cover 20 is rotated to the first state, the first magnetic element 31 and the second magnetic element 32 are directly opposite each other and attract each other magnetically, thus maintaining the flip cover 20 stably in a closed state. In this embodiment, both the first magnetic element 31 and the second magnetic element 32 can be permanent magnets, or one can be a permanent magnet and the other a ferromagnetic material that can be attracted by magnetic force, such as an iron sheet. Furthermore, the magnetic adsorption method makes the opening and closing operation smooth and responsive, improving the user experience.
[0027] The video receiver speaker provided in this application provides a stable protective space for the microphone 200 by setting a receiving cavity 11 to accommodate the microphone 200. Furthermore, by using the first magnetic suction member 31 and the second magnetic suction member 32 respectively set on the first housing 16 and the flip cover 20 to attract each other, a stable and continuous magnetic holding force can be provided when the flip cover 20 is closed, which effectively prevents the flip cover 20 from accidentally popping open due to device tilting, vibration or movement, thus improving the reliability of microphone 200 storage. In addition, in this application, the speaker 80 can be independently installed and fixed on the inner wall of the second housing 17 and its wiring can be completed. At the same time, the flip cover 20 of the first housing 16 and the suction component 30 can be assembled as independent modules. The assembly of the two functional modules can be carried out simultaneously and finally assembled together, thereby improving assembly efficiency.
[0028] In some embodiments, the first housing 16 has a first mounting groove 13 on the cavity wall opposite to the flip cover 20, and the first magnetic member 31 is embedded in the first mounting groove 13. The first mounting groove 13 is located on the cavity wall opposite to the flip cover 20, that is, when the flip cover 20 is closed, the cavity wall is located on the side opposite to the flip cover 20. The shape of the first mounting groove 13 matches the shape of the first magnetic member 31. For example, if the first magnetic member 31 is a disc magnet, then the first mounting groove 13 is a corresponding cylindrical blind hole; if it is a square magnet, then it is a square groove. The first magnetic member 31 is securely embedded in the first mounting groove 13. The specific fixing method can be interference fit, adhesive bonding, or a snap-fit 222 structure designed at the opening of the first mounting groove 13 to prevent it from falling out.
[0029] By setting the first mounting groove 13, the first magnetic component 31 is provided with mechanical positioning and support. This installation method is more secure than simply sticking it to the surface. It can effectively resist vibration and impact that may occur during use, prevent the first magnetic component 31 from loosening or falling off due to long-term force, and ensure the long-term reliability of the magnetic holding function.
[0030] In some embodiments, the flip cover 20 includes a third housing 21 rotatably connected to the first housing 16 and a fourth housing 22 covering the side of the third housing 21 facing the first housing 16. The side of the fourth housing 22 facing the third housing 21 is provided with a second mounting groove 221, and a second magnetic member 32 is embedded in the second mounting groove 221. When the flip cover 20 is in the first state, the first magnetic member 31 corresponds to the second magnetic member 32.
[0031] The shape of the second mounting groove 221 matches the shape of the second magnetic component 32. For example, if the second magnetic component 32 is a disc magnet, then the second mounting groove 221 is a corresponding cylindrical blind hole; if it is a square magnet, then it is a square groove. The second magnetic component 32 is securely embedded in the second mounting groove 221. The specific fixing method can be interference fit, adhesive bonding, or a snap-fit structure 222 designed at the opening of the second mounting groove 221 to prevent it from falling out. Optionally, the third housing 21 and the fourth housing 22 can be fixedly connected by screws, snap-fit structures 222, etc. The sandwich space formed by the third housing 21 and the fourth housing 22 provides an ideal mounting position and wiring space for possible additional functional components, enhancing the design expandability of the product.
[0032] By setting the second mounting groove 221, mechanical positioning and support are provided for the second magnetic component 32. This installation method is more secure than simply sticking it to the surface. It can effectively resist vibration and impact that may occur during use, prevent the first magnetic component 31 from loosening or falling off due to long-term stress, and ensure the long-term reliability of the magnetic holding function.
[0033] In some embodiments, the video player speaker also includes a hinge assembly 50, through which the flip cover 20 is rotatably connected to the first housing 16. The hinge assembly 50 provides a precise, low-resistance rotating shaft 53, ensuring smooth and stable rotation of the flip cover 20 throughout the opening and closing process, greatly enhancing the user's operating experience.
[0034] In some embodiments, the rotating shaft assembly 50 includes a first blade 51, a second blade 52, and a rotating shaft 53 connected to the second blade 52. The first blade is connected to the first housing 16, the second blade 52 is connected to the fourth housing 22 on the side facing the third housing 21, and the rotating shaft 53 is rotatably connected to the first blade 51. The fourth housing 22 is provided with a clearance notch 224 for avoiding the first blade 51.
[0035] In this embodiment, the first sheet 51 and the second sheet 52 are metal or high-strength plastic sheets, which are fixedly connected to the first housing 16 or the fourth housing 22 at a predetermined position by means of screws, riveting, or snap-fit. Optionally, the first sheet 51 is located on the bottom side of the first housing 16, and the position of the second sheet 52 corresponds to the position of the first sheet 51. A rotating shaft 53 is connected to the second sheet 52, and the rotating shaft 53 passes through the corresponding shaft hole on the first sheet 51, forming a clearance fit with the shaft hole or being connected through a bearing, thereby realizing the relative rotation between the first sheet 51 and the rotating shaft 53.
[0036] Furthermore, to ensure smooth operation of the aforementioned structure without interference, a clearance notch 224 is provided on the fourth housing 22. The shape and size of this notch are precisely designed to ensure that the first leaf 51, fixed to the first housing 16, can always freely extend into or pass through this clearance notch 224 without colliding with any solid part of the fourth housing 22 during the entire rotation of the flip cover 20. The second leaf 52 of the pivot assembly 50 is connected to the inner side of the fourth housing 22, and the rotation center of the pivot 53 is "hidden" between the third housing 21 and the fourth housing 22. This achieves an inward shift of the pivot 53 connection point, allowing the pivot assembly 50 to be partially housed inside the flip cover 20, saving external space and making the product profile simpler and thinner. Additionally, by setting the hinge pivot 53 structure, when the flip cover 20 is opened and forms a preset angle with the side wall of the first housing 16, the flip cover 20 can be stably maintained at the preset angle. In this embodiment, the preset angle formed between the flip cover 20 and the side wall of the first housing 16 can reach 90° or greater.
[0037] In some embodiments, the first housing 16 has a mounting wall 14, a receiving cavity is disposed in the mounting wall 14, and a buckle 222 is provided on the side of the flip cover 20 away from the rotating shaft assembly 50. The mounting wall 14 has a buckle groove 15 adapted to the buckle 222. When the flip cover 20 is in the first state, the buckle 222 is engaged and fixed with the buckle groove 15. In this embodiment, the buckle 222 can be fixed by screws, snap-fit, or integrally injection molded with the fourth housing 22 of the flip cover 20 and disposed on the inner side of the flip cover 20. The buckle 222 may form a hook at its end, the shape of which is precisely adapted to the buckle groove 15.
[0038] When the flip cover 20 is fully in the first state, the hook of the latch 222 moves to a position directly opposite the latch groove 15 on the mounting wall 14. The latch 222 quickly snaps in and engages within the latch groove 15, accompanied by a slight "click" as confirmation feedback. At this time, the flip cover 20 is simultaneously subjected to the magnetic attraction force of the magnetic assembly and the mechanical locking force of the latch 222 and the latch groove 15. When it is necessary to open the flip cover 20, the user only needs to apply a pulling force slightly greater than the magnetic attraction force to the free end of the flip cover 20. This pulling force must overcome the locking force between the latch 222 and the latch groove 15, causing the latch 222 to disengage from the latch groove 15, and the flip cover 20 can then smoothly rotate to the second state. In this embodiment, in addition to the original magnetic fixation, a latch 222 and a latch 222 locking the latch 222 of the latch groove 15 are added. This further enhances the ability of the flip cover 20 to retain its position in the first state. In particular, it can effectively resist external forces caused by device drops, violent handling, or accidental impacts from the free end, ensuring that the microphone 200 will not fall off due to the flip cover 20 popping open in harsh transportation or use environments.
[0039] In some embodiments, the flip cover 20 is provided with a limiting groove 223 on the side facing the opening 111. The limiting groove 223 is adapted to the shape of the portion of the microphone 200 exposed outside the opening 111. When the flip cover 20 is in the first state, the limiting groove 223 is used to limit the microphone 200. When the flip cover 20 is closed, the limiting groove 223 can cover the portion of the microphone 200 exposed outside the opening 111 of the receiving cavity 11 (such as part of the sidewall of the microphone 200). This provides additional positioning constraints for the microphone 200 in the vertical and horizontal directions, effectively preventing the microphone 200 from shaking, rotating or axially moving inside the receiving cavity 11 due to device movement, handling or vibration, and improving the stability of the microphone 200 storage.
[0040] In some embodiments, the rotation axis of the flip cover 20 extends horizontally, and the axis of the receiving cavity 11 is parallel to the rotation axis of the flip cover 20. Multiple receiving cavities 11 are spaced apart, and the spacing direction of each receiving cavity 11 is perpendicular to the rotation axis direction of the flip cover 20. By providing multiple independent receiving cavities 11, the speaker can simultaneously provide protected storage space for multiple microphones 200, improving the functionality and practicality of the product. Furthermore, arranging two receiving cavities 11 spaced apart along a direction perpendicular to the rotation axis (i.e., vertically) is an extremely compact space utilization method, fully utilizing the vertical height space of the side wall of the first housing 16, rather than the horizontal width space. This makes the width occupied by the multi-microphone 200 storage structure on the horizontal plane almost the same as that of the single-cavity structure, maintaining the simplicity of the product's side profile and its overall compactness. Optionally, in this embodiment, two receiving cavities 11 are spaced apart.
[0041] In some embodiments, the video player speaker further includes a buffer 40, which is connected to the side wall of the first housing 16 or the flip cover 20. When the flip cover 20 is in the first state, the buffer 40 is sandwiched between the flip cover 20 and the side wall of the first housing 16, and the buffer 40 is used to buffer the impact on the speaker body 10 when the flip cover 20 is closed. In this embodiment, the buffer 40 can be connected to the inner side wall of the flip cover 20, or it can be connected to the side wall of the first housing 16, or both the inner side wall of the flip cover 20 and the side wall of the first housing 16 can be connected to the buffer 40. The buffer 40 can be made of a material with elastic and damping properties, such as silicone, rubber, or polyurethane foam. When the flip cover 20 is in the first state, the inner side wall of the flip cover 20 is not in direct rigid contact with the side wall of the first housing 16, but rather in contact with the side wall of the first housing 16 through the buffer 40. In other words, in the first state, the buffer 40 is slightly compressed between the flip cover 20 and the first housing 16. Therefore, when the user closes the flip cover 20 or the flip cover 20 is accidentally closed due to external force, the buffer 40 can effectively absorb the impact energy, significantly reduce or eliminate the impact noise generated when closing, and improve the user experience. Secondly, it avoids direct hard friction and impact between the flip cover 20 and the surface of the first housing 16, protects the coating or material on both surfaces, and improves the service life of the product.
[0042] In some embodiments, two buffer members 40 are arranged at intervals, with the two buffer members 40 located on opposite sides of the receiving cavity 11. In this embodiment, each buffer member 40 can be fixed to a preset position on the side wall of the first housing 16 by means of adhesive, snap-fit 222, or screw connection. When the flip cover 20 rotates toward the side wall of the first housing 16 to close, the inner side wall of the flip cover 20 will simultaneously contact the two buffer members 40 located on both sides of the opening 111. The two symmetrically arranged buffer members 40 ensure that the buffering force on both sides of the flip cover 20 is balanced at the moment of closing, which helps to prevent the flip cover 20 from tilting or shaking slightly due to force on one side, making the closing action smoother. Moreover, compared with only a single buffer member 40, the two-point support can disperse the impact force when the flip cover 20 closes to two positions, avoiding excessive concentration of impact force in a certain local area of the side wall of the first housing 16, reducing the risk of deformation or damage to the first housing 16 or the flip cover 20 due to long-term point impact, thereby improving the long-term reliability of the structure. Optionally, the two buffers 40 are symmetrically distributed about the center of the receiving cavity 11.
[0043] In other possible embodiments, multiple buffer members 40 are spaced apart, and each buffer member 40 is arranged circumferentially around the receiving cavity 11. In other possible embodiments, the buffer member 40 has a ring-shaped structure, which is fixed to the side wall of the first housing 16 and arranged around the opening 111 of the receiving cavity 11. When the flip cover 20 is closed, the inner side wall of the flip cover 20 presses against the buffer member 40. The ring-shaped buffer member 40 not only further improves the buffering performance, but also gives the receiving cavity 11 a good dustproof and moisture-proof sealing function, providing additional protection for the microphone 200.
[0044] In some embodiments, the speaker body 10 is provided with two connection holes 18, which are spaced apart and located on opposite side walls of the speaker body 10. The video player speaker also includes a handle assembly 60 and a rotating connection assembly 70. The handle assembly 60 includes a handle portion 61 and two rotating portions 62 connected to both ends of the handle portion 61. Two rotating connection assemblies 70 are spaced apart and connected to the two connection holes 18. The two rotating portions 62 are rotatably connected to the two rotating connection assemblies 70. The rotating connection assembly 70 includes a connector 71 and a shaft member 72. The connector 71 is embedded in the connection hole 18, the shaft member 72 is detachably connected to the connector 71, and the rotating portion 62 is rotatably sleeved on the shaft member 72.
[0045] On opposite side walls of the speaker body 10, a connecting hole 18 is provided, preferably a countersunk hole or a stepped hole, for accommodating and positioning the rotating connecting assembly 70. Additionally, the handle 61 is in the shape of an arc-shaped rod, strip, or other ergonomic form suitable for user grip, and can be made of a material with sufficient strength, such as metal or engineering plastic. Two rotating parts 62 are fixedly connected to both ends of the handle 61, for example, by integral molding, welding, riveting, or threaded fastening.
[0046] In this embodiment, the shape of the connector 71 matches the shape of the connecting hole 18. The connector 71 is fixedly embedded in the connecting hole 18 by means of interference fit, bonding, snap-fit 222 connection or screw connection, etc. Its outer end face can be basically flush with or slightly concave with the outer surface of the side wall of the speaker body 10 to achieve a flat appearance. The material of the connector 71 can be selected independently of the speaker body 10 as needed. For example, it can be made of metal materials with higher strength and better wear resistance (such as aluminum alloy, zinc alloy) or reinforced engineering plastics.
[0047] By embedding the connector 71 into the connection hole 18, the main body of the rotating connection assembly 70 can be housed inside the speaker body 10, effectively reducing the space occupied by the entire video camera speaker. Furthermore, by setting an independent connector 71 and embedding it into the connection hole 18 on the speaker body 10, the connector 71 can be flexibly replaced according to actual needs. For example, depending on different strength requirements, a different material from the speaker body 10 can be selected for manufacturing, such as using higher strength engineering materials, so that the connector 71 can be adapted to different application scenarios, thereby improving the applicability of the video camera speaker.
[0048] In addition, the handle 61 is sleeved on the shaft member 72 through the rotating part 62 at its end, and the shaft member 72 and the connecting member 71 are detachably connected. The structure is simple and has few parts. Users can quickly disassemble or install the handle assembly 60 without tools or with only simple tools, which greatly reduces the installation and maintenance costs.
[0049] In some embodiments, the connector 71 is provided with a threaded hole 711, and one end of the shaft 72 is threadedly connected to the threaded hole 711. In this embodiment, the connector 71 has a threaded hole 711 at its center along its axial direction; correspondingly, one end of the shaft 72 is provided with an external thread section that matches the threaded hole 711. The specific assembly and connection relationship is as follows: First, the connector 71 is fixedly embedded in the connecting hole 18 of the speaker body 10, ensuring that the axis of its threaded hole 711 coincides with the axis of rotation; then, the shaft 72 is passed through the rotating part 62, so that the external thread section at one end is aligned and screwed into the threaded hole 711 of the connector 71. By rotating the shaft 53, the shaft 72 can be fastened to the connector 71. In this state, the rotating part 62 is rotatably fitted onto the smooth shaft portion of the shaft member 72, thereby achieving a reliable rotatable connection between the handle assembly 60 and the speaker body 10. Furthermore, the entire rotatable connection assembly 70, through the embedded installation of the connector 71, forms a flat or recessed integrated appearance with the side wall of the speaker body 10. The threaded engagement between the shaft member 72 and the connector 71 ensures a high degree of tightness and connection stability, allowing the handle assembly 60 to be disassembled and reinstalled multiple times.
[0050] In some embodiments, the shaft member 72 includes a rod portion 721 threadedly connected to a threaded hole 711 and a limiting portion 722 connected to the end of the rod portion 721 away from the connector 71. The rotating portion 62 is provided with a through hole 621 for the rod portion 721 to pass through. The limiting portion 722 is arranged around the periphery of the rod portion 721. The rotating portion 62 is limited between the side wall of the speaker body 10 and the limiting portion 722.
[0051] The rod portion 721 is the main body of the shaft member 72, with an external threaded section at one end for engaging with the threaded hole 711 in the center of the connector 71, achieving a detachable fastening connection. The remaining portion of the rod portion 721 is a smooth cylindrical surface. A limiting portion 722 is fixedly connected to the end of the rod portion 721 away from the connector 71. The limiting portion 722 is arranged around the periphery of the rod portion 721, and its radial dimension is larger than the diameter of the rod portion 721. In this embodiment, the limiting portion 722 can specifically be a nut head integrally formed with the rod portion 721, or it can be an independent part fixed to the end of the rod portion 721 by threaded connection, riveting, or snap fastener 222, such as a flange, snap ring, or washer combination.
[0052] Correspondingly, a through hole 621 is provided on the rotating part 62 of the handle assembly 60. The inner diameter of the through hole 621 is slightly larger than the diameter of the smooth portion of the rod 721 of the shaft member 72, but smaller than the radial dimension of the limiting part 722. During assembly, the connector 71 is pre-fitted into the connecting hole 18 of the speaker body 10. The rotating part 62 of the handle assembly 60 is placed in position so that its through hole 621 is aligned with the threaded hole 711 of the connector 71. One end of the shaft member 72 is passed through the through hole 621 of the rotating part 62, so that the external threaded section of one end of the rod 721 is screwed into the threaded hole 711 of the connector 71 and tightened. After the shaft member 72 is tightened, the rotating part 62 is securely axially limited between the side wall of the speaker body 10 and the limiting part 722 of the shaft member 72. The through hole 621 of the rotating part 62 and the smooth part of the rod 721 form a rotating pair, allowing the handle assembly 60 to rotate freely around the axis of the shaft 72. The limiting part 722, together with the side wall of the speaker, effectively prevents the rotating part 62 from accidentally axially dislodging from the rod 721. Optionally, the shaft 72 can be a bolt or screw.
[0053] In some embodiments, the rotating part 62 has a first protrusion 622 on its surface facing the limiting part 722, and the first protrusion 622 abuts against the limiting part 722 along the axial direction of the through hole 621. In this embodiment, the first protrusion 622 protrudes axially from the end face of the rotating part 62. After the shaft member 72 is assembled and tightened, the top end of the first protrusion 622 will directly contact and abut against the inner surface of the limiting part 722, that is, the surface facing the speaker body 10. Therefore, the rotating part 62 does not contact the limiting part 722 with its entire end face, but only through the first protrusion 622 to make point contact or line contact with the limiting part 722.
[0054] By transforming the large-area surface contact between the rotating part 62 and the limiting part 722 into a small-area point contact or line contact, the contact surface area between the two is effectively reduced. This effectively reduces the sliding friction resistance generated by the rotating part 62 during rotation, making the swinging action of the handle lighter and smoother, greatly improving the user's hand feel, and helping to reduce wear on the contact parts during long-term use. It also avoids rotation jamming or abnormal noise that may be caused by uneven surface wear, thus improving the durability and long-term stability of the components.
[0055] In some embodiments, the first protrusion 622 is an annular structure, arranged around the axis of the through hole 621. Specifically, the first protrusion 622 is a continuous annular boss that rises coaxially around the axis of the through hole 621 from the end face of the rotating part 62 toward the limiting part 722. The cross-sectional shape of the annular boss can be rectangular, trapezoidal, arc-shaped, etc., which avoids excessive local stress or slight tilting of the rotating part 62 that may be caused by uneven force distribution, thereby ensuring the stability of the handle assembly 60 during rotation. In other possible embodiments, the first protrusion 622 is a raised dot structure, and multiple first protrusions 622 are arranged at intervals, each first protrusion 622 arranged around the axis of the through hole 621, further reducing the contact area and thus further reducing frictional resistance.
[0056] In some embodiments, the rotating connection assembly 70 further includes a bushing 73 sleeved on the shaft member 72. The bushing 73 is disposed between the side wall of the speaker body 10 and the rotating part 62. The surface of the bushing 73 facing the rotating part 62 is provided with a fixing groove 731. The rotating connection assembly 70 also includes an elastic member 74 installed in the fixing groove 731 and having an elastic restoring force. The elastic member 74 is sandwiched between the bottom wall of the fixing groove 731 and the rotating part 62.
[0057] In some embodiments, the rotating part 62 has a second protrusion 623 on its surface facing the bushing 73. The second protrusion 623 corresponds to the elastic member 74, and the elastic member 74 is sandwiched between the bottom wall of the fixing groove 731 and the second protrusion 623. After the shaft member 72 is finally assembled and tightened, the top end of the second protrusion 623 will abut against the surface of the elastic member 74 facing the rotating part 62. At this time, the elastic member 74 is stably sandwiched between the bottom wall of the fixing groove 731 and the top end of the second protrusion 623, improving the stability of the installation of the elastic member 74.
[0058] In some embodiments, the elastic member 74 and the second protrusion 623 are both annular, and the elastic member 74 and the second protrusion 623 are arranged around the axis of the through hole 621. The annular second protrusion 623 has a continuous annular contact surface at its top. After the shaft member 72 is assembled and tightened, this annular contact surface will uniformly press against the also annular elastic member 74, so that the elastic member 74 is subjected to a consistent compressive force from the second protrusion 623 throughout its entire circumference. At this time, the annular elastic member 74 is stably and coaxially clamped between the bottom wall of the annular fixing groove 731 and the top surface of the annular second protrusion 623, further improving the positional stability of the elastic member 74.
[0059] In other possible embodiments, the second protrusion 623 is a convex structure, and multiple second protrusions 623 are arranged at intervals. Each second protrusion 623 is arranged around the axis of the through hole 621, which further reduces the contact area and can save materials.
[0060] In some embodiments, the speaker body 10 has a mounting port 19 that connects the accommodating cavity 12 and the external space; the video camera speaker also includes a protective structure, with the speaker 80 embedded in the mounting port 19. The protective structure includes a first mesh cover 91 and a second mesh cover 92. The first mesh cover 91 and the second mesh cover 92 are detachably connected to the outer surface of the speaker body 10 and cover the sound output side of the speaker 80. The first mesh cover 91 and the second mesh cover 92 are made of different materials.
[0061] In this embodiment, at least one mounting opening 19 is provided on the front, rear, or side wall of the speaker body 10. The mounting opening 19 connects the accommodating cavity 12 with the external space. The speaker 80 is embedded and fixed in the mounting opening 19 to convert electrical signals into sound and radiate it. The first mesh cover 91 and the second mesh cover 92 have roughly the same outline, but they are made of different materials. The first mesh cover 91 and the second mesh cover 92 can provide physical protection for the fragile speaker 80, preventing foreign objects from impacting or intruding.
[0062] In one specific embodiment, the first mesh cover 91 can be made of metal, such as iron mesh, stainless steel mesh, or aluminum alloy mesh. Its structure is robust, providing strong protection, and the metallic texture enhances the product's appearance and durability. The second mesh cover 92 can be made of fiber fabric, such as sound-permeable mesh, waterproof mesh, or fleece mesh. Its soft texture minimizes the diffraction and attenuation of high-frequency sound waves and more effectively prevents fine dust from entering.
[0063] By setting the first mesh cover 91 and the second mesh cover 92, iron mesh or cloth mesh can be freely selected to be installed according to different installation requirements or usage environments. This customizable design greatly satisfies the user's personalized needs, enriches the functions of the video player speaker, and improves the applicability of the video player speaker.
[0064] In some embodiments, the protective structure further includes a first bracket 93 and a second bracket 94, wherein the first bracket 93 is used to detachably connect the first mesh cover 91 to the speaker body 10, and the second bracket 94 is used to detachably connect the second mesh cover 92 to the speaker body 10.
[0065] The connection methods between the first mesh cover 91 and the first bracket 93, and between the second bracket 94 and the second mesh cover 92, differ. For example, the first mesh cover 91 can be pre-installed and securely embedded in the first bracket 93 by methods such as edge pressing, insertion into a groove, screw fixing, or adhesive bonding, forming an integral structure. Similarly, the second mesh cover 92 can be pre-installed and securely mounted on the second bracket 94 by methods such as tightening and inserting into a groove, heat-sealing the edges, or fixing with a pressure ring. Through the first bracket 93 and the second bracket 94, dedicated fixing structures can be designed for the first mesh cover 91 and the second mesh cover 92 respectively, allowing for the adoption of optimal fixing processes based on their material properties.
[0066] In some embodiments, the video receiver speaker also includes a display screen 95. The display screen 95 has a display surface and is rotatably connected to the top surface of the first housing 16. The display screen 95 has a third state and a fourth state. When the display screen 95 is in the third state, it is stacked on the top surface of the first housing 16, with the display surface in contact with the top surface of the first housing 16. When the display screen 95 is in the fourth state, it is angled relative to the top surface of the first housing 16, so that the display surface of the display screen 95 is exposed. The display screen 95 can switch between the third and fourth states. In the third state, the surface of the display screen 95 facing away from the first housing 16 serves as a support plane, which can stably support external devices such as mobile phones and tablets. In the fourth state, it maintains the traditional display function, thus integrating display and support functions into the video receiver speaker, enriching the functionality of the video receiver speaker and improving its practicality.
[0067] In summary, the video camera speaker provided in this application provides a stable protective space for the microphone 200 by setting up a receiving cavity 11 to house the microphone 200. Furthermore, by utilizing the mutual attraction of the first magnetic suction member 31 and the second magnetic suction member 32 respectively disposed on the first housing 16 and the flip cover 20, a stable and continuous magnetic holding force can be provided when the flip cover 20 is closed, effectively preventing the flip cover 20 from accidentally popping open due to device tilting, vibration, or movement, thus improving the reliability of microphone 200 storage. In addition, in this application, the speaker 80 can be independently installed and fixed on the inner wall of the second housing 17, and its wiring connection can be completed. At the same time, the flip cover 20 of the first housing 16 and the suction component 30 can be assembled as independent modules. The assembly of the two functional modules can be carried out simultaneously and finally assembled together, thereby improving assembly efficiency.
[0068] The above are merely optional embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of the claims of this application.
