Description

Technical Field

[0001] This utility model relates to the field of home appliance technology, and in particular to a display device. Background Technology

[0002] With the increasing prevalence of smart TVs, far-field voice control has become an essential feature, enabling users to control the TV via voice interaction without needing a remote control or moving around. A microphone is installed on the TV itself to pick up sound.

[0003] As television bezels become increasingly narrow and thin, the internal space is shrinking. Therefore, existing televisions are trending towards moving the microphone housing to the outside of the television body to meet the requirements of current narrow bezel designs.

[0004] In related technologies, the microphone housing is generally an injection-molded structure. The microphone housing has upward-protruding latches or hooks to secure it to the bottom of the television set. However, forming the latches or hooks inside the microphone housing results in a relatively complex size and higher injection molding costs. Utility Model Content

[0005] The purpose of this utility model is to provide a display device that facilitates the engagement of the microphone box at the bottom of the lower front shell and reduces production costs.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] According to one aspect of the present invention, a display device is provided, including a back plate, a lower front shell, and a microphone housing; a display panel for displaying image information is provided on the front side of the back plate; the lower front shell is disposed at the bottom end of the back plate; a downwardly protruding hook portion is formed on the bottom surface of the lower front shell; the hook portion is provided with an extension section and an overlapping section, the extension section extends downward from the bottom surface of the lower front shell, and the overlapping section bends from the end of the extension section away from the lower front shell and extends in the left-right direction.

[0008] The microphone housing has an open upper cavity for accommodating a far-field control board; a limiting protrusion extending in the left-right direction is formed on the inner wall of the cavity; the lower side of the limiting protrusion overlaps the upper side of the overlapping section, so as to drive the upper end of the microphone housing to abut against the bottom surface of the lower front shell.

[0009] The above-mentioned technical features have at least the following technical effects and advantages:

[0010] The pickup box has an open-top cavity. A limiting protrusion extending in the left-right direction is formed on the inner wall of the cavity. A downwardly protruding hook portion is formed on the bottom surface of the lower front shell. The hook portion has an extension section and an overlapping section. The extension section extends downward from the bottom surface of the lower front shell, and the overlapping section bends from the end of the extension section away from the lower front shell and extends upward. The lower side of the limiting protrusion overlaps the upper side of the overlapping section, exerting an upward force on the limiting protrusion. This causes the upper end of the pickup box to press against the bottom surface of the lower front shell, thus restricting the pickup box to the bottom of the lower front shell.

[0011] Compared to the existing technology where the microphone box has a hook or buckle structure, the microphone box in this application has a limiting protrusion. The limiting protrusion has a simpler structure, which facilitates the production and manufacturing of the microphone box and thus reduces production costs.

[0012] In some embodiments of this application, the hook portions are spaced two apart in the left-right direction; the limiting protrusions are spaced two apart in the left-right direction; and the two extensions of the two hook portions respectively abut against the opposite end faces of the two limiting protrusions.

[0013] The above-mentioned technical features have at least the following technical effects and advantages:

[0014] The two extended sections of the two hooks abut against the opposite end faces of the limiting protrusions, thereby restricting the lateral movement of the pickup box relative to the lower front shell. The upper end face of the pickup box fits against the bottom surface of the lower front shell, and the overlapping section overlaps with the lower side of the limiting protrusion, restricting the vertical movement of the lower front shell. Through the cooperation of the extended sections of the hooks and the limiting sections, the vertical and horizontal movement of the pickup box relative to the lower front shell is restricted.

[0015] In some embodiments of this application, there is a gap between the front end of the limiting protrusion and the front sidewall of the accommodating cavity; after the upper end face of the pickup box body is attached to the bottom surface of the lower front shell, the overlapping section can extend downward into the gap, so that the overlapping section can move backward relative to the limiting protrusion to overlap the lower side of the limiting protrusion.

[0016] The above-mentioned technical features have at least the following technical effects and advantages:

[0017] During installation, the microphone housing can move upward relative to the lower front shell, allowing the lower end of the hook to extend into the gap between the front end of the limiting protrusion and the front side wall of the accommodating cavity. The microphone housing moves forward, causing the limiting protrusion to move forward as well, so that the lower side of the limiting protrusion positions the microphone housing on the bottom surface of the lower front shell. In some embodiments of this application, a positioning hole is provided on the bottom surface of the lower front shell; horizontally extending elastic arms are formed at both ends of the microphone housing, with one end of the elastic arm suspended; an upwardly protruding positioning protrusion is formed on the suspended section of the elastic arm; the positioning protrusion extends into and is positioned within the positioning hole; after the elastic arm undergoes downward deformation, the positioning protrusion can disengage from the positioning hole.

[0018] The above-mentioned technical features have at least the following technical effects and advantages:

[0019] The positioning protrusion is positioned within the positioning hole to limit the horizontal (front-back, left-right) movement of the remote support relative to the lower front shell. When disassembling the microphone housing, the elastic arm needs to be pressed down; the elastic arm deforms downwards, causing the positioning protrusion to disengage from the positioning hole. The positioning protrusion's positioning within the positioning hole limits the microphone housing's horizontal movement relative to the lower front shell, ensuring the reliability of the microphone housing's upper limit positioning within the lower front shell.

[0020] In some embodiments of this application, the elastic arm extends in a front-rear direction, and the rear end of the elastic arm extends beyond the rear end of the lower front housing, so that the elastic arm can be pressed downward.

[0021] The above-mentioned technical features have at least the following technical effects and advantages:

[0022] The rear end of the elastic arm extends beyond the rear end of the lower front shell, making it easy to press the elastic arm so that the positioning protrusion can be dislodged from the positioning hole, facilitating the disassembly of the pickup box.

[0023] In some embodiments of this application, the lower front shell is a structure made of metal material, and the hook part is a structure formed by stamping and bending on the lower front shell.

[0024] The above-mentioned technical features have at least the following technical effects and advantages:

[0025] In related technologies, the lower front shell is a structure formed by injection molding of plastic material. If the hook part is made of plastic, it is prone to breakage, and those skilled in the art would not consider providing a hook part on a plastic lower front shell. In this application, the lower front shell is a structure made of metal material, and the hook part is also made of metal. The metal hook part has greater strength and can undergo greater elastic deformation, so that the elastic deformation of the hook part can adapt to the resistance and separation from the limiting protrusion.

[0026] In some embodiments of this application, the bottom surface of the lower front shell has a fixing hole; a fixing tongue is formed on the pickup box body; the fixing tongue extends upward beyond the upper end of the pickup box body; the fixing tongue extends upward into and engages in the fixing hole to restrict the downward movement of the pickup box body relative to the lower front shell.

[0027] The above-mentioned technical features have at least the following technical effects and advantages:

[0028] The retaining tab engages within the retaining hole, restricting the downward movement of the pickup box relative to the lower front shell, thereby ensuring the stability and reliability of the pickup box's fixation on the lower front shell.

[0029] In some embodiments of this application, the retaining tongue includes an upwardly extending protruding section and a snap-fit ​​section extending forward from the protruding section; the lower surface of the snap-fit ​​section overlaps the lower front shell.

[0030] The above-mentioned technical features have at least the following technical effects and advantages:

[0031] The lower surface of the snap-fit ​​section overlaps with the lower front shell, restricting the downward movement of the pickup box relative to the lower front shell.

[0032] In some embodiments of this application, the far-field control board is provided with multiple indicator lights, which are spaced apart in the left-right direction; the front side of the pickup box is provided with multiple light-transmitting holes that penetrate into the accommodating cavity; the light-transmitting holes are provided corresponding to the indicator lights.

[0033] The above-mentioned technical features have at least the following technical effects and advantages:

[0034] The front side of the microphone housing has multiple light-transmitting holes that extend into the receiving cavity; these holes correspond to indicator lights. Different light-transmitting holes correspond to different indicator lights to indicate different functions.

[0035] In some embodiments of this application, the accommodating cavity is provided with a plurality of vertically spaced partitions; the front and rear ends of the partitions are connected to the sidewalls of the accommodating cavity; the partitions divide the accommodating cavity into a plurality of cavities; and the plurality of indicator lights are located in different cavities.

[0036] The above-mentioned technical features have at least the following technical effects and advantages:

[0037] The partition divides the accommodating cavity into multiple cavities, with multiple indicator lights located in different cavities to avoid mutual interference between the indicator lights.

[0038] In some embodiments of this application, a rear shell is also included; the rear shell covers the back of the back plate; the bottom end of the rear shell extends forward to form a base plate; a forward-protruding limiting bracket is formed on the front side of the rear shell; the limiting bracket is located above the base plate; a rearward-protruding rear edge is formed at the rear end of the pickup box; the upper and lower sides of the rear edge are respectively attached to the base plate and the limiting bracket.

[0039] The above-mentioned technical features have at least the following technical effects and advantages:

[0040] The rear end of the pickup box has a rearward protruding rear edge, and the upper and lower sides of the rear edge are respectively attached to the bottom plate of the rear shell and the limiting bracket protrusion to restrict the vertical movement of the rear end of the rear shell.

[0041] Other features and advantages of this application will become apparent from the following detailed description, or may be learned in part from practice of this application.

[0042] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and do not limit this application. Attached Figure Description

[0062] Figure 1 This is a schematic diagram of the structure of the display device of this utility model. Figure 2 This is a partial structural schematic diagram of the display device of this utility model.

[0063] See Figure 1 and Figure 2 This application provides a display device, including a back panel (not shown) and a microphone housing 200 disposed at the bottom of the display body. The microphone housing 200 houses a remote control module and / or a microphone module. The microphone module receives external remote control signals for remote control of the display device. In some embodiments, the microphone module can also receive voice signals emitted by a user and convert the sound into electrical signals for controlling the display device, thus enabling voice interaction. The display device is a flat-panel TV or computer monitor, etc.

[0064] The display body may include a back plate (not shown in the figure), which is the main support component of the display device. A mounting cavity is formed on the front side of the back plate for mounting structures such as light sources and optical film assemblies.

[0065] The back panel is vertically oriented. A forward-protruding bezel is formed along the periphery of the back panel; the bezel is circumferential and extends around the edge of the back panel. The bezel extends forward beyond the front side of the back panel, and the bezel and back panel together form a front-opening mounting cavity for mounting the backlight and optical film assembly. The display panel is fixed to the front end of the bezel.

[0066] The frame can be a middle frame that fixes the periphery of the back panel. The middle frame covers the edge of the back panel and surrounds the four edges of the back panel. In some embodiments, the frame and the back panel are integrally formed, and the edge of the back panel extends forward to form the frame, which is circumferentially arranged.

[0067] The specific structure of the backplate is described in reference to the structure of the backplate in the relevant technology, and will not be repeated here.

[0068] The bottom of the back panel is provided with a lower front shell 10, and the microphone box 200 is provided on the bottom surface of the lower front shell.

[0069] In other embodiments, the display device may further include a display panel 500, which is fixed to the front side of a back plate. The display panel 500 is used to display image information for user viewing. A mounting cavity is formed between the front side of the back plate and the rear side of the display panel by a gap, within which an optical film assembly and a light source are disposed. Light emitted from the light source passes through the optical film assembly and displays image information on the display panel.

[0070] The backlight is used to emit light. The backlight and the optical film group are arranged in parallel. The backlight is located on the light-incident side behind the optical film group so as to emit light toward the optical film group. The optical film group is located in front of the backlight so that after the light passes through the optical film group, uniform white light is obtained on the light-emitting side in front of the optical film group.

[0071] In some embodiments, the backlight is an LED panel, which is attached to the bottom surface of the mounting cavity and emits white light towards the optical film assembly. In some embodiments, the backlight and the optical film assembly are spaced apart in the vertical direction to form a light mixing distance. In other embodiments, the backlight and the optical film assembly are attached together in the vertical direction.

[0072] An optical film assembly is positioned in front of and spaced from the backlight source to improve the uniformity and brightness of the light source. The optical film assembly includes a diffuser plate and multiple films arranged sequentially. The multiple films may include brightness enhancement plates and multiple prism sheets, or multiple films may include multiple prism sheets.

[0073] The display panel is located in front of the optical film group. The light from the optical film group is transmitted forward to the display panel. The liquid crystal molecules in the display panel are deflected by the electric field, reducing the transmittance of the light emitted from the optical film group into the liquid crystal panel, and thus projecting the light into filters of different colors to form an image.

[0074] In some embodiments, the display device may further include a rear housing 300, which is fixed to the back of a back panel. An accommodating space is formed between the front side of the rear housing 300 and the rear side of the back panel. Electronic components are disposed on the rear side of the back panel, within the accommodating space. The electronic components include a motherboard, a power board, a speaker, and a power strip. The electronic components are fixed to the back of the back panel and located within the coverage area of ​​the rear housing 300, thereby protecting them. The motherboard is primarily used for calculations on the control system and for outputting relevant operating commands. The motherboard is located between the back of the back panel and the rear housing 300 and is fixed to the back of the back panel.

[0075] In some embodiments, the motherboard is primarily used to perform calculations on the control system of the display device and output relevant operation instructions. The motherboard has a large number of electronic components, mainly responsible for transmitting the operation instructions output by the motherboard to the corresponding operating terminals.

[0076] The power supply board is set separately or integrated on the motherboard and fixed to the back of the backplate. Its main purpose is to provide the motherboard with drive voltage or stable operating voltage and to keep the output current of the circuits on the motherboard stable when they are working.

[0077] Other driving components include speakers and power strips. The speakers are located on the back of the rear panel and are primarily used to produce corresponding sounds in conjunction with the interface displayed on the display panel. The power strip has multiple different types of interfaces for connecting external devices to receive or output signals to them. In some embodiments, the power strip is integrated onto the motherboard. Other driving components may be structures such as remote control modules or voice modules.

[0078] Figure 3 This is a structural schematic diagram of the lower front shell 100 of this utility model from one perspective. Figure 4 This is a structural schematic diagram of the lower front shell 100 of this utility model from another perspective.

[0079] See Figures 2 to 4 The display device may further include a lower front cover 100, which is fixed to the bottom of the back panel and extends in the left-right direction. The lower front cover 100 is disposed at the bottom of the housing and the display panel, and the lower front cover 100 covers the bottom of the back panel and the display panel. After the lower front cover 100 is separately machined, the microphone box 200 is positioned on the bottom surface of the lower front cover 100, so that the microphone box 200 is installed at the bottom of the display body.

[0080] In other embodiments, the bottom edge of the back panel extends rearward to form the lower front shell 100, which is integrally formed on the back panel.

[0081] In some embodiments, the lower front housing 100 may include a front wall 110 and an extension wall 120 extending rearward from the lower end of the front wall 110. The front wall 110 forms the front side surface of the lower front housing 100, and the extension wall 120 extends rearward from the bottom edge of the front wall 110, covering the bottom ends of the display panel and the back panel. The microphone housing 200 is positioned on the bottom surface of the extension wall 120.

[0082] In other embodiments, the lower front housing 100 may consist only of the extension wall 120, with the microphone housing 200 positioned on the bottom surface of the extension wall 120.

[0083] In some embodiments, a fixing hole 130 may be provided on the bottom surface of the lower front shell 100. Specifically, a fixing hole 130 is provided on the bottom surface of the extension wall 120 to cooperate with the corresponding structure of the pickup box 200 and to engage the pickup box 200 on the extension wall 120.

[0084] The fixing hole 130 extends vertically through the upper and lower sides of the extension wall 120 so that the corresponding structure of the pickup box 200 can pass through the bottom surface of the extension wall 120 upwards.

[0085] In some embodiments, the extension wall 120 forms an overlapping platform 131 on the front side of the fixing hole 130. The rear end of the overlapping platform 131 communicates with the front side of the fixing hole 130, and the upper surface of the overlapping platform 131 is lower than the upper surface of the extension wall 120. The corresponding structure of the pickup box 200 extends into the fixing hole 130 and overlaps on the overlapping platform 131.

[0086] In this embodiment, the upper surface of the extension wall 120 is recessed in front of the fixing hole 130 to form an overlapping platform 131. In other embodiments, the overlapping platform 131 is not provided in the fixing hole 130, and the corresponding structure of the far-field module extends into the fixing hole 130 and overlaps on the upper surface of the extension wall 120.

[0087] Multiple fixing holes 130 are spaced apart in the left-right direction. In this embodiment, two fixing holes 130 are spaced apart in the left-right direction. In some embodiments, the fixing holes 130 can be one, three, or four, etc., with multiple fixing holes 130 spaced apart in the left-right direction, and their projections in the left-right direction overlap.

[0088] In some embodiments, the bottom surface of the lower front cover 100 may have a downwardly protruding hook portion 140. One or more hook portions 140 may be provided.

[0089] In some embodiments, two hook portions 140 are provided, which are arranged opposite to each other and spaced apart. The opposite sides of the two hook portions 140 abut against corresponding structures on the pickup box 200 to restrict the movement of the pickup box 200 along the relative directions of the two hook portions 140.

[0090] The hook portion 140 extends downward from the bottom surface of the extension wall 120, and the lower end of the hook portion 140 is suspended in the air. The suspended end of the hook portion 140 is elastic and can undergo elastic deformation.

[0091] In the prior art, the lower front shell 100 is a plastic injection-molded structure. The hook part 140 is made of plastic, and the plastic hook part 140 is at risk of breakage. Therefore, when using a plastic lower front shell 100, the hook part 140 is generally not used. In this application, the lower front shell 100 is a structure made of metal. Specifically, the lower front shell 100 is a structure made of aluminum alloy. The metal hook part 140, while ensuring that the hook part 140 can undergo elastic deformation, can effectively prevent the hook part 140 from breaking, ensuring the reliability of limiting the pickup box 200.

[0092] In some embodiments, two hook portions 140 are spaced apart in the left-right direction, and the ends of the two hook portions 140 extend away from each other in the left-right direction. In other embodiments, two hook portions 140 are spaced apart in the front-back direction, and the ends of the two hook portions 140 extend away from each other in the front-back direction.

[0093] The ends of the two hooks 140 extend in opposite directions. When the two hooks 140 abut against the corresponding structures on the pickup box 200, the structures with the ends of the hooks 140 extending in opposite directions provide an upward force to the pickup box 200 to keep the pickup box 200 attached to the bottom surface of the lower front shell 100.

[0094] In some embodiments, the hook portion 140 may include an extension 141 and an overlapping section 142; the extension 141 extends downward from the bottom surface of the lower front housing 100, and the overlapping section 142 is located at the end of the extension 141, bending from the end of the extension away from the lower front housing and extending in a left-right direction. The upper surface of the overlapping section is used to overlap the lower surface of the corresponding structure of the pickup housing, thereby providing an upward force to the pickup housing and holding it in place.

[0095] In other embodiments, two hook portions 140 are provided, with overlapping sections 142 of the two hook portions 140 extending in opposite directions. The distance between the overlapping sections 142 of the two hook portions 140 gradually increases in the direction away from the extension wall 120.

[0096] In some embodiments, the two hook portions 140 are spaced apart in the left-right direction, and the overlapping sections 142 on the two hook portions 140 are inclined downward in opposite directions in the left-right direction.

[0097] The lower front shell 100 is a structure made of metal, and the hook part 140 is stamped and formed on the extension wall 120. The hook part 140 is integrally formed on the lower front shell 100.

[0098] In this application, a positioning hole 150 is provided on the bottom surface of the lower front shell 100. The positioning hole 150 is located on the bottom surface of the extension wall 120 and is positioned near the hook part 140. There are two positioning holes 150, each corresponding to one hook part 140. The two positioning holes 150 are located on opposite sides of the hook part 140.

[0099] Figure 5 This is a structural schematic diagram of the pickup box 200 of this utility model from one perspective. Figure 6 This is a structural schematic diagram of the pickup box 200 of this utility model from another perspective. Figure 7 This is a schematic diagram showing the connection of the pickup box 200 of this utility model to the lower front shell 100.

[0100] See Figures 2 to 7 The microphone housing 200 is located below the lower front cover 100 and is detachably mounted on the bottom surface of the lower front cover 100. The microphone housing 200 has an open-top cavity 210 for accommodating the far-field control board 400. The far-field control board 400 is located inside the microphone housing 200 and is used for voice interaction with the user.

[0101] The upper surface of the microphone box 200 is attached to the bottom surface of the lower front shell 100, and the microphone box 200 is engaged and limited at the bottom of the lower front shell 100 so that the microphone box 200 is located at the lower part of the display body, which facilitates the collection of the user's voice information.

[0102] A retaining latch 220 is formed on the pickup housing 200. The retaining latch 220 extends upward beyond the upper end of the pickup housing 200 and engages with the retaining hole 130 to restrict the downward movement of the pickup housing 200 relative to the lower front shell 100. The upper end face of the pickup housing 200 abuts against the bottom surface of the extension wall 120, restricting the upward movement of the pickup housing 200. The retaining latch 220 engages with the retaining hole, restricting the downward movement of the pickup housing 200. By limiting the vertical movement of the pickup housing 200, the vertical movement of the pickup housing 200 is restricted.

[0103] When the pickup box 200 is installed on the extension wall 120, the fixing tongue 220 can extend upward into the fixing hole 130, and the fixing tongue 220 can move in the front-back direction within the fixing hole 130 so that the fixing tongue 220 moves forward to overlap the extension wall 120.

[0104] The retaining tab 220 may include an upwardly extending protruding section 221 and a snap-fit ​​section 222 that bends from the protruding section 221 and extends forward. When the microphone housing 200 is engaged with the extension wall 120, the lower surface of the snap-fit ​​section 222 overlaps with the lower front housing 100. Specifically, the snap-fit ​​section 222 overlaps with the extension wall 120. When the snap-fit ​​section 222 overlaps with the extension wall 120, the microphone housing 200 can move in the front-rear direction to facilitate the assembly and disassembly of the microphone housing 200 on the lower front housing 100.

[0105] The lower surface of the latching section 222 abuts against the overlapping platform 131 at the fixing hole 130, and there is a gap between the upper end of the latching section 222 and the upper surface of the extension wall 120. The upper end of the latching section 222 is lower than the upper surface of the protruding section 221. When the pickup box 200 is disassembled or assembled, there is a gap between the latching section 222 and the upper surface of the extension wall 120, so that when the pickup box 200 moves relative to the extension wall 120, the movement of the latching section 222 will not interfere with other components inside the lower front shell 100, so as to facilitate the disassembly and assembly of the pickup box 200 on the lower front shell 100.

[0106] The upper end of the pickup box 200 is attached to the lower surface of the extension wall 120; the lower surface of the fixing latch 220 overlaps the extension wall 120. Specifically, the lower surface of the latching section 222 of the fixing latch 220 overlaps the overlapping platform 131, restricting the vertical movement of the pickup box 200.

[0107] The fixing tongue 220 is located at the front end of the pickup box 200. The fixing tongue 220 engages within the fixing hole 130, restricting the downward movement of the front end of the pickup box 200. The upper edge of the front end of the pickup box 200 is attached to the bottom surface of the lower front shell 100. The front end of the latching section 222 extends beyond the front end face of the pickup box 200 and overlaps the extension wall 120, so as to tightly attach the front end of the pickup box 200 to the bottom surface of the extension wall 120, avoiding gaps between the front end of the pickup box 200 and the extension wall 120.

[0108] In some embodiments, the microphone housing has an open-top cavity, and a limiting protrusion extending in a left-right direction is formed on the inner wall of the cavity. A downwardly protruding hook portion is formed on the bottom surface of the lower front shell. The hook portion is provided with an extension section and an overlapping section. The extension section extends downward from the bottom surface of the lower front shell, and the overlapping section bends from the end of the extension section away from the lower front shell and extends in the direction. The lower side of the limiting protrusion overlaps the upper side of the overlapping section, exerting an upward force on the limiting protrusion, causing the upper end of the microphone housing to abut against the bottom surface of the lower front shell, thus restricting the microphone housing to the bottom of the lower front shell.

[0109] Furthermore, two hook portions 140 are provided, which are arranged opposite to each other and spaced apart. The pickup box body 200 has an open-top receiving cavity 210, and two opposing extending limiting protrusions 230 are formed within the receiving cavity 210. The ends of the two hook portions 140 respectively stop at the opposite ends of the limiting protrusions 230 to restrict the movement of the pickup box body 200 along the extending direction of the limiting protrusions 230. The ends of the hook portions 140 extend away from each other, and the ends of the hook portions 140 stop at the opposite ends of the limiting protrusions 230, and the hook portions 140 exert an upward force on the limiting protrusions 230. The upper surface of the pickup box 200 is attached to the bottom surface of the lower front shell 100. The upward force exerted by the end of the hook part 140 on the pickup box 200 ensures that the pickup box 200 is pressed upward against the bottom surface of the lower front shell 100, thus restricting the vertical movement of the pickup box 200.

[0110] Compared to the existing technology where the pickup box 200 has a hook or buckle structure, the pickup box 200 in this application has a limiting protrusion 230. The structure of the limiting protrusion 230 is simpler, which facilitates the production and manufacturing of the pickup box 200 and can reduce production costs.

[0111] In some embodiments, the hook portion 140 on the lower front shell 100 includes an extension portion 141 and an overlapping portion 142; the overlapping portions 142 of the two hook portions 140 extend in opposite directions; the extension portion 141 abuts against the limiting protrusion 230; the overlapping portion 142 overlaps the bottom surface of the limiting protrusion 230. The two extension portions 141 of the two hook portions 140 abut against the limiting protrusion 230 respectively, thereby restricting the left-right movement of the pickup box 200 relative to the lower front shell 100. The upper end face of the pickup box 200 is attached to the bottom surface of the lower front shell 100, and the overlapping portion 142 overlaps the bottom surface of the limiting protrusion 230, restricting the up-down movement of the lower front shell 100. Through the cooperation of the extension portion 141 and the limiting portion on the hook portion 140, the up-down and left-right movement of the pickup box 200 relative to the lower front shell 100 is restricted.

[0112] In some embodiments, a gap exists between the front end of the limiting protrusion and the front sidewall of the receiving cavity; after the upper end face of the pickup box body is abutted against the bottom surface of the lower front shell, the overlapping section can extend downward into the gap, so that the overlapping section can move rearward relative to the limiting protrusion to overlap the lower side of the limiting protrusion. During pickup box body installation, the pickup box body can move upward relative to the lower front shell, so that the lower end of the hook portion can extend into the gap between the front end of the limiting protrusion and the front sidewall of the receiving cavity. The pickup box body moves forward, causing the limiting protrusion to move forward, thereby positioning the pickup box body on the bottom surface of the lower front shell.

[0113] In related technologies, the lower front shell 100 is a structure formed by injection molding of plastic material. If the hook part 140 is a plastic structure, the plastic hook part 140 is prone to breakage, and those skilled in the art would not think of setting the hook part 140 on the plastic lower front shell 100. In this application, the lower front shell 100 is a structure made of metal material, and the hook part 140 is made of metal material. The metal hook part 140 has greater strength and can undergo greater elastic deformation, so that the elastic deformation of the hook part 140 can adapt to the abutment and separation of the limiting protrusion 230.

[0114] In some embodiments, horizontally extending elastic arms 240 are formed at both ends of the microphone housing 200, with one end of the elastic arm 240 suspended; the suspended section of the elastic arm 240 is formed with an upwardly protruding positioning protrusion 250; the two elastic arms 240 are suspended at one end, so that the elastic arm 240 is elastic and can be deformed, thereby driving the positioning protrusion 250 to move up and down.

[0115] In some embodiments, a protruding positioning protrusion 250 is formed on the upper surface of the elastic arm 240; the positioning protrusion 250 extends into and is limited within the positioning hole 150 on the bottom surface of the lower front housing 100; after the elastic arm 240 deforms downward, the positioning protrusion 250 can disengage from the positioning hole 150. The positioning protrusion 250 is limited within the positioning hole 150 to restrict the movement of the remote support relative to the lower front housing 100 in the horizontal direction (front-back and left-right direction). When disassembling the microphone housing 200, the elastic arm 240 needs to be pressed downward, and the elastic arm 240 deforms downward, causing the positioning protrusion 250 to disengage from the positioning hole 150. The limitation of the positioning protrusion 250 within the positioning hole 150 restricts the movement of the microphone housing 200 relative to the lower front-back horizontal direction to ensure the reliability of the microphone housing 200's upper limit position on the lower front housing 100.

[0116] After the elastic arm 240 is pressed and the positioning protrusion 250 disengages from the positioning hole 150, the pickup box 200 moves backward. The backward movement of the pickup box 200 causes the hook part 140 and the limiting protrusion 230 to separate, and also causes the fixing tongue 220 and the overlapping platform 131 to separate, so that the pickup box 200 can move downward relative to the lower front shell 100 and separate.

[0117] In one specific embodiment, the elastic arm 240 extends in the front-rear direction, with the front end of the elastic arm 240 suspended in the air; the rear end of the elastic arm 240 is connected to the housing of the pickup box 200, and the positioning protrusion 250 is provided on the upper surface of the front end of the elastic arm 240, with the rear end of the elastic arm 240 extending beyond the rear end of the lower front shell 100.

[0118] In another embodiment, the elastic arm 240 extends in the front-rear direction, and the rear end of the elastic arm 240 is suspended; the front end of the elastic arm 240 is connected to the housing of the pickup box 200, the positioning protrusion 250 is provided on the upper surface of the elastic arm 240, and the rear end of the elastic arm 240 extends beyond the rear end of the lower front shell 100.

[0119] The rear end of the elastic arm 240 extends beyond the rear end of the lower front shell 100 so that the elastic arm can be pressed down to facilitate pressing the elastic arm 240 and facilitating the disassembly of the pickup box 200.

[0120] In another embodiment, one end of the elastic arm 240 facing the middle of the pickup box 200 is connected to the housing of the pickup box 200, and the other end of the elastic arm 240 facing away from the middle of the pickup box 200 is suspended. A positioning protrusion 250 is provided on the upper surface of the suspended end of the elastic arm 240. For example, the elastic arm 240 extends in the left-right direction, and the end of the elastic arm 240 facing the middle of the pickup box 200 in the left-right direction is connected to the housing of the pickup box 200.

[0121] Figure 8 This is a partial structural schematic diagram of the rear shell 300 of this utility model. Figure 9 This is a schematic diagram showing the connection between the pickup box 200 and the rear shell 300 of this utility model.

[0122] See Figures 5 to 9 The rear cover 300 is fitted onto the back of the back panel; the bottom end of the rear cover 300 extends forward to form a base plate 310, and the rear end of the pickup box 200 forms a rear edge 260 that protrudes backward. The rear edge 260 of the pickup box 200 is attached to the base plate 310, and the rear edge 260 overlaps the upper surface of the base plate 310, thereby restricting the downward movement of the rear end of the pickup box 200.

[0123] In some embodiments, a forward-protruding limiting protrusion 320 is formed on the front side of the rear shell 300; the limiting protrusion 320 is located above the base plate 310; the upper and lower sides of the rear edge 260 are respectively attached to the base plate 310 and the limiting protrusion 320. The rear end of the pickup box 200 is formed with a rearward-protruding rear edge 260, the upper and lower sides of the rear edge 260 are respectively attached to the base plate 310 and the limiting protrusion 320 of the rear shell 300 to restrict the vertical movement of the rear end of the rear shell 300.

[0124] The rear end of the rear edge 260 of the pickup box 200 abuts against the rear shell 300, restricting the rearward movement of the pickup box 200. Specifically, a stop rib 330 is formed between the lower surface of the limiting protrusion 320 and the front side of the rear shell 300, and the rear end of the rear edge 260 of the pickup box 200 abuts against the stop rib 330.

These indicator lights may include a power indicator light 410, a far-field indicator light 420, a remote control infrared guide light 430, etc.

[0127] The front side of the microphone housing 200 has multiple light-transmitting holes 270 that extend into the receiving cavity 210; these light-transmitting holes 270 correspond to indicator lights. Different light-transmitting holes 270 correspond to different indicator lights to indicate different functions.

[0128] In some embodiments, the accommodating cavity 210 is provided with a plurality of vertically spaced partitions 280; the front and rear ends of the partitions 280 are respectively connected to the sidewalls of the accommodating cavity; the partitions 280 divide the accommodating cavity 210 into a plurality of cavities; the plurality of indicator lights are respectively located in different cavities. The partitions 280 divide the accommodating cavity 210 into a plurality of cavities, and the plurality of indicator lights are respectively located in different cavities, so as to avoid mutual interference between the lights of the indicator lights.
