[0007] The second frame component is rotatably connected to the rotating mechanism. At least one of the second frame component and the first frame component is provided with a voice playing device, and the voice playing device is arranged on a side away from the rotating mechanism.

[0008] Beneficial effects: By setting a voice acquisition device and an intelligent voice main control module on the rotating mechanism, the voice acquisition device can collect voice instructions, and the intelligent voice main control module can control the adjustment unit to adjust the heater according to the collected voice instructions. By setting a voice playback device, the intelligent voice main control module can issue interactive instructions according to the collected voice instructions, and play them out through the voice playback device. Therefore, the user can adjust the electric heater and obtain the adjustment feedback information of the electric heater without going near the electric heater, which is convenient to operate and has a good user experience. And because the voice acquisition device is arranged on the rotating mechanism, the voice playback device is arranged on the side away from the rotating mechanism, and the voice acquisition device is far away from the voice playback device, the secondary transmission of the sound played by the voice playback device to the voice acquisition device can be avoided, and the occurrence of crosstalk and reverberation can be avoided. In addition, because the voice playback device is arranged on the side away from the rotating mechanism, the conduction and radiation interference to other electrical components inside the rotating mechanism is relatively small.

[0009] In an optional embodiment, the rotating mechanism includes:

[0010] The upper cavity assembly includes a main board, the main board is provided with the intelligent voice main control module, the upper cavity assembly is provided with the voice collection device, and the voice collection device is connected to the main board;

[0011] The lower cavity assembly is fixedly connected to the upper cavity assembly. The lower cavity assembly is provided with two rotating connection parts on one side facing the upper cavity assembly. The first frame assembly and the second frame assembly are respectively connected to the rotating connection parts.

[0012] Beneficial effect: The upper cavity component includes a main board, and the voice collection device is arranged in the upper cavity component. Water is not easy to accumulate inside the upper cavity component, which can prevent the main board, the voice collection device, and the intelligent voice main control module from being affected.

[0013] In an optional embodiment, the upper cavity assembly has a first area, and during the rotation of the first frame assembly and the second frame assembly, the first area is located outside the projections of the first frame assembly and the second frame assembly on the upper frame assembly, and the voice collection device is arranged in the first area.

[0014] Beneficial effect: Since the first area is located outside the projections of the first frame component and the second frame component on the upper frame component, that is, no matter what angle the first frame component and the second frame component are rotated to, the first area will not be blocked. By arranging the voice collection device in the first area, it can be ensured that the first frame component and the second frame component will not block the voice collection device, thereby ensuring that the voice commands issued by the user can be collected.

[0015] In an optional embodiment, the upper cavity assembly includes:

[0016] The upper cover is provided with a sound pickup hole, and the main board is arranged inside the upper cover;

[0017] An upper cover plate is fixedly connected to the upper cover, and the voice collection device is installed on the upper cover plate and close to the sound pickup hole.

[0018] Beneficial effect: By setting a sound pickup hole in the upper cover, the voice collection device is installed on the upper cover plate and close to the sound pickup hole, and the user's voice command can be transmitted to the voice collection device through the sound pickup hole. In addition, the setting of the sound pickup hole can prevent water from entering the interior of the upper cover.

[0019] In an optional embodiment, the sound pickup hole includes a first hole segment and a second hole segment, the first hole segment is located outside the second hole segment, the first hole segment and the second hole segment are both trumpet-shaped, and the opening angle of the first hole segment is greater than the opening angle of the second hole segment.

[0020] Beneficial effect: The first hole segment and the second hole segment are both trumpet-shaped, and the opening angle of the first hole segment is greater than the opening angle of the second hole segment, which can prevent water from entering the interior of the upper cover through the sound pickup hole.

[0021] In an optional implementation, the voice collection device is installed on the upper cover plate by interference fit.

[0022] Beneficial effect: The voice collection device is installed on the upper cover plate by interference fit, and the connection method between the voice collection device and the upper cover plate is simple and convenient, which can improve the assembly efficiency.

[0023] In an optional embodiment, the upper cover plate is provided with a limiting rib, and the voice collection device is installed on the inner side of the limiting rib by interference fit.

[0024] Beneficial effects: The voice collection device is installed on the inner side of the limiting rib with interference fit. The connection between the voice collection device and the upper cover is simple and convenient, which can improve the assembly efficiency. The limiting rib can wrap the voice collection device to block the sound transmitted by the voice playback device, thereby reducing the interference of the sound transmitted by the voice playback device on the voice collection device.

[0025] In an optional implementation, the voice collection device fits with the upper cover with zero clearance.

[0026] Beneficial effect: Since the voice collection device and the upper cover are matched with zero clearance, the voice command entering through the sound pickup hole can be directly collected by the voice collection device.

[0027] In an optional embodiment, the upper cover plate is provided with a first water leakage hole.

[0028] Beneficial effect: By setting the first water leakage hole on the upper cover, when water enters the upper cover through the sound pickup hole, it can leak downward through the first water leakage hole, thereby avoiding the accumulation of water inside the upper cavity component to affect the mainboard, voice collection equipment, and intelligent voice main control module.

[0029] In an optional embodiment, the lower cavity assembly includes:

[0030] Tripod;

[0031] A lower cover plate, mounted on the tripod, the lower cover plate being provided with a second water leakage hole and a flow guiding structure, the flow guiding structure being in communication with at least one of the second water leakage holes;

[0032] The base is arranged on the upper side of the tripod, the base is connected to the upper cover plate, and the base is provided with the rotating connection part.

[0033] Beneficial effect: By arranging a second water leakage hole and a guide structure on the lower cover plate, when water enters the upper cover through the sound pickup hole, it leaks downward through the first water leakage hole and falls on the lower cover plate. The guide structure guides the water falling on the lower cover plate to the second water leakage hole, and flows downward through the second water leakage hole, thereby avoiding water accumulation on the lower cover plate.

[0034] In an optional embodiment, a mounting bracket is provided on a side of the first frame assembly and / or the second frame assembly away from the rotating mechanism, the mounting bracket is provided with a positioning structure, and the voice playback device is fixed to the mounting bracket via the positioning structure.

[0035] Beneficial effect: By arranging a positioning structure on the mounting bracket, it is convenient to install and fix the voice playback device.

[0036] In an optional embodiment, the first frame assembly and the second frame assembly include a frame body and a shell provided at a side of the frame body away from the rotating mechanism, and the sound outlet of the voice playback device faces the shell.

[0037] Beneficial effect: Since the sound outlet of the voice playback device is toward the shell, the sound outlet direction is far away from the voice collection device, which can avoid the secondary transmission of the sound played by the voice playback device to the voice collection device, and avoid crosstalk and reverberation.

[0038] In an optional embodiment, a cavity is formed between the sound outlet and the mounting bracket, the shell is provided with a sound outlet, and the cavity is communicated with the sound outlet.

[0039] Beneficial effect: a cavity is formed between the sound outlet and the mounting bracket, and the sound played by the voice playback device is transmitted through the cavity, and the sound is more concentrated and clear.

[0040] In an optional embodiment, the shell is provided with a shutter structure, and the sound outlet is arranged on the shutter structure.

[0041] Beneficial effect: The sound outlet is arranged in the shutter structure, so that the sound can be output in multiple positions and the sound output range is wider. In addition, the shutter structure can block the water flow outside the shell and prevent water from entering the first frame assembly or the second frame assembly.

[0042] In an optional embodiment, the mounting bracket includes a first side surface abutting the end of the frame body, a top surface, and a second side surface arranged on the top surface close to one end of the shell, the lower end of the second side surface and the lower end of the second side surface form an opening, the top surface is a slope, and the shell is provided with guide ribs, and the guide ribs extend toward the frame body at the lower side of the mounting bracket and form a flow channel with the frame body.

[0043] Beneficial effect: When water passes through the mounting bracket, since the top surface is an inclined surface, the water will not stay on the top surface, but will flow downward along the second side surface, pass through the guide ribs extending from the shell, and then flow downward through the flow channel, thereby preventing the voice playback device from being immersed in water.

[0044] In an optional embodiment, a drainage hole is provided at the bottom of the shell, and the flow passage is communicated with the drainage hole.

[0045] Beneficial effect: Water falling from the mounting bracket flows downward through the flow passage after passing through the guide ribs extending from the shell, and is finally discharged through the drainage hole, thereby avoiding water accumulation inside the first frame assembly and the second frame assembly.

[0046] In an optional embodiment, a plurality of ribs are provided inside the frame body.

[0047] Beneficial effect: Since a plurality of ribs are arranged inside the frame body, the ribs increase the propagation path of the sound emitted by the voice playback device to the voice collection device. The ribs can consume the sound energy emitted by the voice playback device, avoid the secondary transmission of the sound played by the voice playback device to the voice collection device, avoid crosstalk and reverberation, and thus achieve the sound played by the voice playback device to be adjusted to the maximum, solving the defects of low playback sound and short playback sound transmission distance in related technologies.

DETAILED DESCRIPTION

[0074] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0075] The skirting board heater can be folded and unfolded to meet the different requirements of users. The control methods of skirting board heaters in related technologies include mechanical type (adjusting power through knobs or wave switches); touch button electronic type (also need to go to the prototype and touch the buttons manually to operate); remote control type (need to use a remote control and manually press the buttons on the remote control to operate); WIFI control (need to use a mobile phone APP to operate); online voice (need to use other devices to achieve). Therefore, the related technology is not convenient for controlling skirting board heaters.

[0076] Since the space of the folding skirting board heater is small and the distance between the voice collection device 4 (microphone) and the voice broadcasting device is close, there will be crosstalk (that is, the voice broadcast instructions are collected by the voice collection device 4); the crosstalk will cause the electric heater to repeatedly execute the voice instructions; when the broadcast sound of the speaker encounters some obstacles and produces an echo, the echo is collected by the microphone, which will also cause crosstalk; the sound broadcast by the speaker will produce reverberation and affect the microphone; thereby affecting the accuracy of voice recognition.

[0077] Voice reverberation refers to the phenomenon of multiple echoes caused by reflections from walls, floors, ceilings and other objects when sound propagates in a room or space. These reflected sounds are mixed with the direct sound, which can cause the original sound to become unclear, affecting the auditory experience and the accuracy of speech recognition. In audio processing and voice communication technology, dereverberation technology is usually required to reduce or eliminate these adverse effects to improve the quality and clarity of the sound.

[0078] In addition, the whole machine needs to be equipped with a sound pickup hole to enable the microphone to collect voice commands, and a sound output hole is needed to enable the voice broadcast device to interact with the user. However, both the sound pickup hole and the sound output hole are easy to get water in, causing the whole machine to fail to meet the waterproof requirements.

[0079] The folding skirting board can be folded from 0° to 180°. When folded at 0°, the angle formed by the left and right heating components is 0°. At this time, the sound pickup hole and the sound output hole cannot be blocked, otherwise the offline voice function will fail. The sound pickup hole collects voice commands transmitted through the air, and the voice commands broadcast by the sound output hole are also transmitted to the user through the air. Therefore, the sound pickup hole and the sound output hole cannot be blocked and need to be designed toward the outside of the skirting board heater. As a result, there is less room for choice on the heater.

[0080] When the diameter of the sound pickup hole is small or the number is small, the microphone will not be able to collect voice commands; when the diameter of the sound output hole is small or the number is small, the broadcast voice sound for interaction with the user will be trapped inside the entire machine and cause greater reverberation; and if the diameter of the sound pickup hole and the sound output hole are large and the number is large, the entire machine will not be waterproof.

[0081] Combine the following Figures 1 to 23 , describing an embodiment of the present invention.

[0082] According to an embodiment of the present invention, a baseboard electric heater is provided, comprising a rotating mechanism 1 , a first frame assembly 2 and a second frame assembly 3 .

[0083] Among them, the rotating mechanism 1 is provided with a voice collection device 4 and an intelligent voice main control module; the first frame component 2 is rotatably connected to the rotating mechanism 1; the second frame component 3 is rotatably connected to the rotating mechanism 1, and at least one of the second frame component 3 and the first frame component 2 is provided with a voice playback device 5, and the voice playback device 5 is arranged on a side away from the rotating mechanism 1.

[0084] In this embodiment, by setting a voice acquisition device 4 and an intelligent voice main control module on the rotating mechanism 1, the voice acquisition device 4 can collect voice instructions, and the intelligent voice main control module can control the adjustment unit to adjust the heater according to the collected voice instructions. By setting a voice playback device 5, the intelligent voice main control module can issue interactive instructions according to the collected voice instructions, and play them out through the voice playback device 5. Therefore, the user can adjust the electric heater without going near the electric heater and can obtain the adjustment feedback information of the electric heater, which is convenient to operate and has a good user experience. And because the voice acquisition device 4 is arranged on the rotating mechanism 1, and the voice playback device 5 is arranged on the side away from the rotating mechanism 1, the voice acquisition device 4 is far away from the voice playback device 5, which can avoid the secondary transmission of the sound played by the voice playback device 5 to the voice acquisition device 4, and avoid the occurrence of crosstalk and reverberation. In addition, since the voice playback device 5 is arranged on the side away from the rotating mechanism 1, the conduction and radiation interference to other electrical components inside the rotating mechanism 1 is small.

[0085] Specifically in one embodiment, both the first frame assembly 2 and the second frame assembly 3 are provided with a voice playing device 5 .

[0086] Specifically in one embodiment, the voice collection device 4 refers to a microphone, the voice broadcasting device includes a speaker, and the intelligent voice main control module includes an audio codec unit, an intelligent voice recognition unit and a micro control unit.

[0087] The microphone receives the voice command and sends it to the audio codec unit. The audio codec unit decodes and analyzes the voice command and transmits it to the intelligent voice recognition unit. The intelligent voice recognition unit analyzes the voice command and sends the result to the micro control unit. The micro control unit then sends an adjustment signal to the adjustment unit to adjust the electric heater. At the same time, the intelligent voice recognition unit analyzes the voice command and outputs the interactive command to the voice broadcast device. After receiving the interactive command, the voice broadcast device converts it into voice and plays it out. Therefore, the user can adjust the electric heater without going near the electric heater and can get the adjustment feedback information of the electric heater. The operation is convenient and the user experience is good.

[0088] In one embodiment, the rotating mechanism 1 includes an upper cavity assembly and a lower cavity assembly. The upper cavity assembly includes a main board 101, the upper cavity assembly is provided with a voice acquisition device 4, the main board 101 is provided with an intelligent voice main control module, and the voice acquisition device 4 is connected to the main board 101; the lower cavity assembly is fixedly connected to the upper cavity assembly, and two rotating connecting parts 102 are provided on the side of the lower cavity assembly facing the upper cavity assembly, and the first frame assembly 2 and the second frame assembly 3 are respectively connected to the rotating connecting parts 102.

[0089] In this embodiment, the upper cavity component includes a main board 101, and the voice acquisition device 4 is arranged in the upper cavity component. Water is not easy to accumulate inside the upper cavity component, which can prevent the main board 101, the voice acquisition device 4, and the intelligent voice main control module from being affected.

[0090] Specifically in one embodiment, the rotating connection portion 102 is a shaft sleeve.

[0091] In one embodiment, the upper cavity assembly has a first area. During the rotation of the first frame assembly 2 and the second frame assembly 3, the first area is located outside the projections of the first frame assembly 2 and the second frame assembly 3 on the upper frame assembly, and the voice collection device 4 is arranged in the first area.

[0092] In this embodiment, since the first area is located outside the projections of the first frame component 2 and the second frame component 3 on the upper frame component, that is, no matter to what angle the first frame component 2 and the second frame component 3 are rotated, the first area will not be blocked. By arranging the voice collection device 4 in the first area, it can be ensured that the first frame component 2 and the second frame component 3 will not block the voice collection device 4, thereby ensuring that the voice commands issued by the user can be collected.

[0093] Specifically in one embodiment, the area other than the first area is the second area 103 , and when the first frame assembly 2 and the second frame assembly 3 rotate, the second area 103 is blocked.

[0094] In one embodiment, Figure 1 and Fig.23 As shown, when the angle between the first frame assembly 2 and the second frame assembly 3 is 0°, the distance between the voice collection device 4 and the voice playback device 5 is the farthest. At this time, there are more ribs between the voice collection device 4 and the voice playback device 5 to block the propagation of sound, and the effect of sound propagation is better.

[0095] In one embodiment, the upper cavity assembly includes an upper cover 104 and an upper cover plate 105. The upper cover 104 is provided with a sound pickup hole 1041, the main board 101 is provided in the upper cover 104, and the voice collection device 4 is connected to the main board 101; the upper cover plate 105 is fixedly connected to the upper cover 104, and the voice collection device 4 is installed on the upper cover plate 105 and close to the sound pickup hole 1041.

[0096] In this embodiment, by providing a sound pickup hole 1041 on the upper cover 104, the voice collection device 4 is installed on the upper cover 105 and close to the sound pickup hole 1041, and the user's voice command can be transmitted to the voice collection device 4 through the sound pickup hole 1041. In addition, the provision of the sound pickup hole 1041 can prevent water from entering the interior of the upper cover 104.

[0097] Specifically in one embodiment, Fig.10 and Fig.11As shown, the sound pickup hole 1041 includes a first hole segment 10411 and a second hole segment 10412. The first hole segment 10411 is located outside the second hole segment 10412. The first hole segment 10411 and the second hole segment 10412 are both trumpet-shaped, and the opening angle of the first hole segment 10411 is greater than the opening angle of the second hole segment 10412.

[0098] In this embodiment, the first hole segment 10411 and the second hole segment 10412 are both trumpet-shaped, and the opening angle of the first hole segment 10411 is greater than the opening angle of the second hole segment 10412, which can prevent water from entering the interior of the upper cover 104 through the sound pickup hole 1041.

[0099] It should be noted that the opening angle of the first hole segment 10411 refers to the angle between the extension lines of the upper and lower side walls of the first hole segment 10411 on the longitudinal section of the sound pickup hole 1041; the opening angle of the second hole segment 10412 refers to the angle between the extension lines of the upper and lower side walls of the second hole segment 10412 on the longitudinal section of the sound pickup hole 1041.

[0100] In one embodiment, the upper cavity assembly further includes a display panel 106 and a display board 107. The display panel 106 is fixed to the top of the upper cover 104; and the display board 107 is disposed inside the upper cover 104.

[0101] In this embodiment, the heater can be operated by manipulating the display panel 106 .

[0102] Specifically in one embodiment, a display area and control buttons are provided on the display panel 106 . The display area on the display panel 106 corresponds to the digital display lights on the display panel 107 , and the control buttons on the display panel 106 correspond to the buttons on the display panel 107 .

[0103] In one embodiment, the voice collection device 4 is installed on the upper cover plate 105 by interference fit.

[0104] In this embodiment, the voice collection device 4 is installed on the upper cover plate 105 by interference fit. The connection method between the voice collection device 4 and the upper cover plate 105 is simple and convenient, which can improve the assembly efficiency.

[0105] In one embodiment, the upper cover plate 105 is provided with a limiting rib 1051 , and the voice collection device 4 is installed on the inner side of the limiting rib 1051 by interference fit.

[0106] In this embodiment, the voice collection device 4 is installed on the inner side of the limiting rib 1051 by interference fit. The connection method between the voice collection device 4 and the upper cover plate 105 is simple and convenient, which can improve the assembly efficiency. The limiting rib 1051 can wrap up the voice collection device 4 to block the sound transmitted by the voice playback device 5, thereby reducing the interference of the sound transmitted by the voice playback device 5 on the voice collection device 4.

[0107] In one embodiment, the voice collection device 4 and the upper cover 104 fit together with zero clearance.

[0108] In this embodiment, since the voice collection device 4 and the upper cover 104 are matched with zero clearance, the voice command entering through the sound pickup hole 1041 can be directly collected by the voice collection device 4 .

[0109] In one embodiment, the upper cover plate 105 is provided with a first water leakage hole 1052 .

[0110] In this embodiment, a first water leakage hole 1052 is set on the upper cover 105. When water enters the upper cover 104 through the sound pickup hole 1041, it can leak downward through the first water leakage hole 1052, thereby preventing water accumulation in the upper cavity component from affecting the main board 101, the voice collection device 4, and the intelligent voice main control module.

[0111] In one embodiment, the lower cavity assembly includes a stand 108, a lower cover plate 109 and a base 110. The lower cover plate 109 is mounted on the stand 108, and is provided with a second water leakage hole 1091 and a flow guide structure 1092, and the flow guide structure 1092 is connected to at least one second water leakage hole 1091; the base 110 is disposed on the upper side of the stand 108, and is connected to the upper cover plate 105, and is provided with a rotating connection portion 102.

[0112] In this embodiment, if Fig.15 and Fig.16 , Fig.15 and Fig.16 The direction indicated by the arrow in the figure represents the direction of water flow. By setting a second water leakage hole 1091 and a guide structure 1092 on the lower cover plate 109, when water enters the upper cover 104 through the sound pickup hole 1041, it leaks downward through the first water leakage hole 1052 and falls on the lower cover plate 109. The guide structure 1092 guides the water falling on the lower cover plate 109 to the second water leakage hole 1091, and flows downward through the second water leakage hole 1091, thereby avoiding water accumulation on the lower cover plate 109.

[0113] Specifically in one embodiment, a plurality of second water leakage holes 1091 are provided.

[0114] In one embodiment, the lower cover 109 is provided with a dump switch 111 .

[0115] In this embodiment, by providing a tipping switch 111 on the lower cover 109, when the electric heater tips over, the power supply to the electric heater can be stopped to avoid danger.

[0116] In one embodiment, a mounting bracket 301 is provided on a side of the first frame assembly 2 and / or the second frame assembly 3 away from the rotating mechanism 1 , the mounting bracket 301 is provided with a positioning structure, and the voice playback device 5 is fixed to the mounting bracket 301 via the positioning structure.

[0117] In this embodiment, by providing a positioning structure on the mounting bracket 301 , the voice playback device 5 can be easily installed and fixed.

[0118] Specifically in one embodiment, the positioning structure includes a buckle, a positioning rib, etc.

[0119] In one embodiment, the first frame assembly 2 and the second frame assembly 3 include a frame body 302 and a shell 303 disposed at a side of the frame body 302 away from the rotating mechanism 1 , and the sound outlet 501 of the voice playback device 5 faces the shell 303 .

[0120] In this embodiment, since the sound outlet 501 of the voice playback device 5 is facing the shell 303, the sound output direction is far away from the voice collection device 4, which can avoid the secondary transmission of the sound played by the voice playback device 5 to the voice collection device 4, avoiding crosstalk and reverberation.

[0121] In one embodiment, a cavity is formed between the sound outlet 501 and the mounting bracket 301 , the housing 303 is provided with a sound outlet, and the cavity is communicated with the sound outlet.

[0122] In this embodiment, a cavity is formed between the sound outlet hole 501 and the mounting bracket 301, and the sound played by the voice playing device 5 is transmitted through the cavity, and the sound is more concentrated and clear.

[0123] like Fig.18 , Fig.18 The arrow indicates the direction of the sound.

[0124] In one embodiment, the housing 303 is provided with a shutter structure 3031 , and the sound outlet is provided at the shutter structure 3031 .

[0125] In this embodiment, the sound outlet is arranged on the shutter structure 3031, so that the sound can be output from multiple positions and the sound output range is wider. In addition, the shutter structure 3031 can block the water flow outside the housing and prevent water from entering the first frame assembly 2 or the second frame assembly 3.

[0126] In one embodiment, each window of the shutter structure 3031 is provided with a sound outlet.

[0127] In one embodiment, the mounting bracket 301 includes a first side surface 3011 abutting against the end of the frame body 302, a top surface 3012, and a second side surface 3013 disposed on the top surface 3012 near one end of the shell 303, the lower end of the second side surface 3013 and the lower end of the second side surface 3013 form an opening, the top surface 3012 is an inclined surface, and the shell 303 is provided with a guide rib 3033, which extends toward the frame body 302 at the lower side of the mounting bracket 301 and forms a flow channel with the frame body 302.

[0128] In this embodiment, when water passes through the mounting bracket 301, since the top surface 3012 is a slope, the water will not stay on the top surface 3012, but will flow downward along the second side surface 3013, pass through the guide rib 3033 extending from the shell 303, and then flow downward through the flow channel to prevent the voice playback device 5 from being immersed in water.

[0129] In one embodiment, a drainage hole is provided at the bottom of the housing 303, and the flow passage is connected to the drainage hole.

[0130] In this embodiment, water falling from the mounting bracket 301 passes through the guide ribs 3033 extending from the shell 303 and then flows downward through the flow channel and is finally discharged through the drainage hole, thereby preventing water from accumulating inside the first frame assembly 2 and the second frame assembly 3.

[0131] Specifically in one embodiment, the shell 303 is provided with a heating element bracket 304. The water falling from the mounting bracket 301 passes through the guide ribs 3033 extending from the shell 303 and then flows downward through the flow channel. After passing through the heating element bracket 304, it is finally discharged through the drainage hole.

[0132] In one embodiment, a plurality of ribs are disposed inside the frame body 302 .

[0133] In this embodiment, since a plurality of ribs are arranged inside the frame body 302, the ribs increase the propagation path of the sound emitted by the voice playback device 5 to the voice collection device 4. The ribs can consume the sound energy emitted by the voice playback device 5, avoid the secondary transmission of the sound played by the voice playback device 5 to the voice collection device 4, avoid crosstalk and reverberation, and thus achieve the sound played by the voice playback device 5 to be adjusted to the maximum, solving the defects of low playback sound and short playback sound transmission distance in the related art.

[0134] like Fig. 22 As shown, Fig. 22 The direction indicated by the middle arrow represents the direction of sound propagation. It can be seen that the voice playback device 5 is far away from the voice collection device 4, which avoids the secondary transmission of the sound played by the voice playback device 5 to the voice collection device 4, avoiding crosstalk and reverberation.

[0135] Although the embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations are all within the scope defined by the present application.
