Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, specifically to a skirting board heater. Background Technology

[0002] Baseboard heaters can be folded and unfolded to meet different user needs. Related technologies for baseboard heaters include mechanical control (power adjustment via knobs or toggle switches); electronic control via touch buttons (requiring manual operation by touching buttons at the demo unit); remote control control (requiring manual operation using a remote control); Wi-Fi control (requiring operation via a mobile app); and online voice control (requiring other devices). Therefore, these technologies are not particularly convenient for controlling baseboard heaters. Utility Model Content

[0003] In view of this, the present invention provides a skirting board electric heater to solve the problem of inconvenient control of skirting board electric heaters in related technologies.

[0004] This utility model provides a skirting board electric heater, comprising:

[0005] A rotating mechanism, wherein the rotating mechanism is equipped with a voice acquisition device and an intelligent voice main control module;

[0006] The first frame assembly is rotatably connected to the rotating mechanism;

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

[0008] Beneficial Effects: By incorporating a voice acquisition device and an intelligent voice control module into the rotating mechanism, the voice acquisition device can collect voice commands, and the intelligent voice control module can control the adjustment unit to adjust the heater based on these commands. By setting up a voice playback device, the intelligent voice control module can issue interactive commands based on the collected voice commands, which are then played back through the playback device. Therefore, users can adjust the heater without needing to approach it and receive feedback on the adjustments, making operation convenient and providing a good user experience. Furthermore, because the voice acquisition device is located on the rotating mechanism, while the voice playback device is located on the side furthest from it, the distance between the two devices avoids secondary transmission of sound from the playback device to the voice acquisition device, preventing crosstalk and reverberation. Additionally, the location of the voice playback device on the side furthest from the rotating mechanism minimizes conducted radiation interference to other electrical components within the mechanism.

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

[0010] The upper cavity assembly includes a motherboard, the motherboard being equipped with the intelligent voice main control module, the upper cavity assembly being equipped with the voice acquisition device, and the voice acquisition device being connected to the motherboard;

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

[0012] Beneficial effects: The upper cavity assembly includes the motherboard. The voice acquisition device is located in the upper cavity assembly. Water is less likely to accumulate inside the upper cavity assembly, which can prevent damage to the motherboard, voice acquisition device, and intelligent voice control module.

[0013] In one alternative embodiment, the upper cavity assembly has a first region, and during rotation of the first frame assembly and the second frame assembly, the first region is located outside the projection of the first frame assembly and the second frame assembly onto the upper cavity assembly, and the voice acquisition device is disposed in the first region.

[0014] Beneficial effects: Since the first area is located outside the projection of the first frame component and the second frame component on the upper cavity component, that is, no matter what angle the first frame component and the second frame component rotate to, they will not obstruct the first area. By placing the voice acquisition device in the first area, it can be ensured that the first frame component and the second frame component will not obstruct the voice acquisition device, and that the voice commands issued by the user can be acquired.

[0015] In one alternative implementation, the upper cavity assembly includes:

[0016] The top cover has a microphone hole, and the main board is located inside the top cover;

[0017] A top cover plate is fixedly connected to the top cover, and the voice acquisition device is installed on the top cover plate and close to the sound pickup hole.

[0018] Beneficial effects: By setting a microphone hole in the top cover, the voice acquisition device is installed on the top cover and close to the microphone hole, allowing the user's voice commands to be transmitted to the voice acquisition device through the microphone hole. Furthermore, the microphone hole design prevents water from entering the interior of the top cover.

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

[0020] Beneficial effects: Both the first and second hole sections are funnel-shaped, and the opening angle of the first hole section is greater than that of the second hole section, which can prevent water from entering the interior of the top cover through the sound pickup hole.

[0021] In one alternative implementation, the voice acquisition device is interference-fitted onto the upper cover plate.

[0022] Beneficial effects: The voice acquisition device is interference-fitted onto the top cover plate, and the connection between the voice acquisition device and the top cover plate is simple and convenient, which can improve assembly efficiency.

[0023] In one optional embodiment, the upper cover plate is provided with a limiting rib, and the voice acquisition device is interference-fitted and installed on the inner side of the limiting rib.

[0024] Beneficial effects: The voice acquisition device is installed with an interference fit inside the limiting rib. The connection between the voice acquisition device and the top cover is simple and convenient, which can improve assembly efficiency. In addition, the limiting rib can wrap around the voice acquisition device, blocking the sound transmitted by the voice playback device and reducing the interference of the sound transmitted by the voice playback device on the voice acquisition device.

[0025] In one alternative implementation, the voice acquisition device is fitted with the top cover with zero clearance.

[0026] Beneficial effect: Because the voice acquisition device fits the cover with zero gap, voice commands entering through the pickup hole can be directly acquired by the voice acquisition device.

[0027] In one alternative embodiment, the top cover plate is provided with a first drainage hole.

[0028] Beneficial effect: By setting the first drainage hole in the upper cover, when water enters the upper cover through the microphone hole, it can leak down through the first drainage hole, thus preventing water accumulation inside the upper cavity assembly from affecting the motherboard, voice acquisition device, and intelligent voice control module.

[0029] In one alternative embodiment, the lower cavity assembly includes:

[0030] tripod;

[0031] A lower cover plate is installed on the bracket. The lower cover plate is provided with a second water leakage hole and a flow guiding structure. The flow guiding structure is connected to at least one of the second water leakage holes.

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

[0033] Beneficial effects: By setting a second drainage hole and a flow guiding structure on the lower cover plate, when water enters the upper cover through the sound pickup hole, it leaks down through the first drainage hole and falls onto the lower cover plate. The flow guiding structure directs the water falling onto the lower cover plate to the second drainage hole, and it flows down through the second drainage hole, which can prevent water from accumulating on the lower cover plate.

[0034] In one alternative embodiment, the first frame assembly and / or the second frame assembly are provided with a mounting bracket on the side away from the rotating mechanism, the mounting bracket being provided with a positioning structure, and the voice playback device being fixed to the mounting bracket through the positioning structure.

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

[0036] In one alternative embodiment, the first frame assembly and the second frame assembly include a frame body and a housing located on the side of the frame body away from the rotating mechanism, with the sound outlet of the voice playback device facing the housing.

[0037] Beneficial effects: Because the sound outlet of the voice playback device faces the housing, the sound output direction is away from the voice acquisition device, which can avoid secondary transmission of the sound played by the voice playback device to the voice acquisition device, and avoid crosstalk and reverberation.

[0038] In one optional embodiment, a cavity is formed between the sound outlet and the mounting bracket, the housing is provided with a sound outlet, and the cavity communicates 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, making the sound more focused and clear.

[0040] In one alternative embodiment, the housing is provided with a louver structure, and the sound outlet is located in the louver structure.

[0041] Beneficial effects: The sound outlet is located in a louvered structure, allowing for sound output from multiple positions and a wider sound range. Additionally, the louvered structure can block water flow from outside the casing, preventing water from entering the lower first or second frame assembly.

[0042] In one optional embodiment, the mounting bracket includes a first side surface abutting an end of the frame body, a top surface, and a second side surface disposed on the top surface near one end of the housing. The lower end of the second side surface forms an opening with the lower end of the second side surface. The top surface is an inclined surface. The housing is provided with a flow guide rib. The flow guide rib extends toward the frame body from the lower side of the mounting bracket and forms a flow channel with the frame body.

[0043] Beneficial effect: When water passes through the mounting bracket, because the top surface is sloping, the water will not stay on the top surface, but will flow down along the second side, and after passing through the guide ribs extending from the shell, it will flow down through the flow channel, preventing the voice playback device from being submerged in water.

[0044] In one optional embodiment, the bottom of the housing is provided with a drain hole, and the flow passage communicates with the drain hole.

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

[0046] In one alternative implementation, the frame body has multiple ribs inside.

[0047] Beneficial effects: Because the main frame has multiple ribs inside, the ribs increase the propagation path of the sound emitted by the voice playback device to the voice acquisition device. The ribs can consume the sound energy emitted by the voice playback device, avoid secondary transmission of the sound played by the voice playback device to the voice acquisition device, and avoid crosstalk and reverberation. This allows the sound played by the voice playback device to be turned up to the maximum, solving the defects of low playback volume and short sound transmission distance in related technologies.

[0074] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0075] Baseboard heaters can be folded and unfolded to meet different user needs. Related technologies for baseboard heaters include mechanical control (power adjustment via knobs or toggle switches); electronic control via touch buttons (requiring manual operation by touching buttons at the demo unit); remote control control (requiring manual operation using a remote control); Wi-Fi control (requiring operation via a mobile app); and online voice control (requiring other devices). Therefore, these technologies are not particularly convenient for controlling baseboard heaters.

[0076] Because the space of the folding baseboard heater is small, and the voice acquisition device 4 (microphone) is close to the voice broadcasting device, there will be crosstalk (that is, the voice broadcasting command is also captured by the voice acquisition device 4). After crosstalk, the entire heater will repeatedly execute the voice command. When the broadcasting sound of the speaker encounters some obstacles and produces an echo, the echo is captured by the microphone, which will also cause crosstalk. The sound broadcasting by the speaker will produce reverberation, which will affect the microphone. Thus, the accuracy of voice recognition will be affected.

[0077] Speech reverberation refers to the phenomenon of multiple echoes caused by reflections from walls, floors, ceilings, and other objects as sound propagates through a room or space. These reflected sounds mix with the direct sound, which can make the original sound unclear, affecting the auditory experience and the accuracy of speech recognition. In audio processing and voice communication technologies, dereverberation techniques are often used to reduce or eliminate these adverse effects in order to improve sound quality and clarity.

[0078] In addition, the device needs to have a microphone to collect voice commands and an output hole to enable the voice broadcast device to interact with the user. However, both the microphone and the output hole are prone to water ingress, causing the device to fail to meet waterproof requirements.

[0079] The folding baseboard 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 microphone and sound output holes must not be blocked, otherwise the offline voice function will fail. The microphone picks up 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 microphone and sound output holes cannot be blocked and need to be designed to face outwards from the baseboard heater. This results in less space to choose from when installing the heater.

[0080] If the diameter of the microphone hole is too small or the number of holes is too few, the microphone will not be able to pick up voice commands; if the diameter of the sound outlet hole is too small or the number of holes is too few, the voice broadcasting that interacts with the user will be trapped inside the device and cause greater reverberation; if the diameter of the microphone hole and the number of sound outlet holes are too large, the device will not be waterproof.

[0081] The following is combined with Figures 1 to 23 The following describes embodiments of the present invention.

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

[0083] The rotating mechanism 1 is equipped with a voice acquisition device 4 and an intelligent voice control module; the first frame assembly 2 is rotatably connected to the rotating mechanism 1; the second frame assembly 3 is rotatably connected to the rotating mechanism 1, and at least one of the second frame assembly 3 and the first frame assembly 2 is equipped with a voice playback device 5, and the voice playback device 5 is located on the side away from the rotating mechanism 1.

[0084] In this embodiment, by setting a voice acquisition device 4 and an intelligent voice control module in the rotating mechanism 1, the voice acquisition device 4 can collect voice commands, and the intelligent voice control module can control the adjustment unit to adjust the heater according to the collected voice commands. By setting a voice playback device 5, the intelligent voice control module can issue interactive commands according to the collected voice commands, which are then played out through the voice playback device 5. Therefore, users do not need to walk near the heater to adjust it and can receive adjustment feedback information from the heater, making operation convenient and providing a good user experience. Furthermore, since the voice acquisition device 4 is located in the rotating mechanism 1, and the voice playback device 5 is located on the side away from the rotating mechanism 1, the distance between the voice acquisition device 4 and the voice playback device 5 can avoid secondary transmission of the sound played by the voice playback device 5 to the voice acquisition device 4, avoiding crosstalk and reverberation. In addition, since the voice playback device 5 is located on the side away from the rotating mechanism 1, the conducted radiation interference to other electrical components inside the rotating mechanism 1 is minimal.

[0085] In one specific embodiment, both the first frame component 2 and the second frame component 3 are provided with a voice playback device 5.

[0086] In one specific embodiment, the voice acquisition device includes a microphone, the voice broadcasting device includes a speaker, and the intelligent voice main control module includes an audio encoding / decoding unit, an intelligent voice recognition unit, and a micro control unit.

[0087] The microphone receives voice commands and sends them to the audio codec unit. The audio codec unit decodes and analyzes the voice commands and transmits them to the intelligent voice recognition unit. The intelligent voice recognition unit analyzes the voice commands and sends the results to the micro control unit. The micro control unit then sends adjustment signals to the adjustment unit to adjust the electric heater. Simultaneously, the intelligent voice recognition unit analyzes the voice commands and outputs interactive commands to the voice broadcasting device. The voice broadcasting device receives the interactive commands, converts them into speech, and plays them out. Therefore, users do not need to go near the electric heater to adjust it and can receive adjustment feedback information from the heater, making it convenient to operate and providing a good user experience.

[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, which is equipped with a voice acquisition device 4. The main board 101 is equipped with an intelligent voice 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 the lower cavity assembly has two rotating connecting parts 102 on the side facing the upper cavity assembly. 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 assembly includes a motherboard 101, and the voice acquisition device 4 is located in the upper cavity assembly. Water is less likely to accumulate inside the upper cavity assembly, which can prevent it from affecting the motherboard 101, the voice acquisition device 4, and the intelligent voice main control module.

[0090] In one specific embodiment, the rotating connection 102 is a bushing.

[0091] In one embodiment, the upper cavity assembly has a first region. During rotation, the first frame assembly 2 and the second frame assembly 3 are located outside the projection of the first frame assembly 2 and the second frame assembly 3 onto the upper cavity assembly, and the voice acquisition device 4 is located in the first region.

[0092] In this embodiment, since the first region is located outside the projection of the first frame component 2 and the second frame component 3 on the upper cavity component, that is, no matter what angle the first frame component 2 and the second frame component 3 are rotated, they will not obstruct the first region. By placing the voice acquisition device 4 in the first region, it can be ensured that the first frame component 2 and the second frame component 3 will not obstruct the voice acquisition device 4, and that the voice commands issued by the user can be acquired.

[0093] In one specific embodiment, the area other than the first area is the second area 103, and the second area 103 is blocked when the first frame component 2 and the second frame component 3 rotate.

[0094] In one embodiment, such as Figure 1 and Figure 23 As shown, when the angle between the first frame component 2 and the second frame component 3 is 0°, the distance between the voice acquisition device 4 and the voice playback device 5 is the farthest. At this time, there are more ribs blocking sound propagation between the voice acquisition device 4 and the voice playback device 5, resulting in a better sound propagation effect.

[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 pickup hole 1041, the main board 101 is disposed inside the upper cover 104, and the voice acquisition 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 acquisition device 4 is installed on the upper cover plate 105 and close to the pickup hole 1041.

[0096] In this embodiment, by providing a microphone hole 1041 on the upper cover 104, the voice acquisition device 4 is mounted on the upper cover 105 and close to the microphone hole 1041, allowing the user's voice commands to be transmitted to the voice acquisition device 4 through the microphone hole 1041. Furthermore, the microphone hole 1041 prevents water from entering the interior of the upper cover 104.

[0097] Specifically in one embodiment, such as Figure 10 and Figure 11As shown, the 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. Both the first hole segment 10411 and the second hole segment 10412 are 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, both the first hole segment 10411 and the second hole segment 10412 are funnel-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 sidewalls of the first hole segment 10411 on the longitudinal section of the 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 sidewalls of the second hole segment 10412 on the longitudinal section of the pickup hole 1041.

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

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

[0102] In one specific embodiment, the display panel 106 is provided with a display area and control buttons. The display area on the display panel 106 corresponds to the digital display lights on the display board 107, and the control buttons on the display panel 106 correspond to the buttons on the display board 107.

[0103] In one embodiment, the voice acquisition device 4 is interference-fitted onto the upper cover plate 105.

[0104] In this embodiment, the voice acquisition device 4 is interference-fitted onto the upper cover plate 105. The connection between the voice acquisition device 4 and the upper cover plate 105 is simple and convenient, which can improve assembly efficiency.

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

[0106] In this embodiment, the voice acquisition device 4 is interference-fitted to the inner side of the limiting rib 1051. The connection between the voice acquisition device 4 and the upper cover plate 105 is simple and convenient, which can improve assembly efficiency. In addition, the limiting rib 1051 can wrap the voice acquisition device 4, block the sound transmitted by the voice playback device 5, and reduce the interference of the sound transmitted by the voice playback device 5 to the voice acquisition device 4.

[0107] In one embodiment, the voice acquisition device 4 is fitted with the upper cover 104 with zero clearance.

[0108] In this embodiment, since the voice acquisition device 4 and the upper cover 104 are fitted with zero clearance, the voice commands entering through the pickup hole 1041 can be directly acquired by the voice acquisition device 4.

[0109] In one embodiment, the top cover 105 is provided with a first drainage hole 1052.

[0110] In this embodiment, by providing a first drainage hole 1052 in the upper cover plate 105, when water enters the interior of the upper cover 104 through the sound pickup hole 1041, it can leak downwards through the first drainage hole 1052, thus preventing water accumulation inside the upper cavity assembly from affecting the motherboard 101, the voice acquisition 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 has a second drainage hole 1091 and a flow guiding structure 1092, the flow guiding structure 1092 communicating with at least one second drainage hole 1091; the base 110 is located on the upper side of the stand 108 and is connected to the upper cover plate 105, and the base 110 has a rotatable connection part 102.

[0112] In this embodiment, such as Figure 15 and Figure 16 , Figure 15 and Figure 16 The arrows in the diagram indicate the direction of water flow. By providing a second drain hole 1091 and a flow guiding structure 1092 on the lower cover plate 109, when water enters the interior of the upper cover 104 through the sound pickup hole 1041, it leaks down through the first drain hole 1052 and falls onto the lower cover plate 109. The flow guiding structure 1092 guides the water falling onto the lower cover plate 109 to the second drain hole 1091, and it flows down through the second drain hole 1091, which can prevent water accumulation on the lower cover plate 109.

[0113] In one specific embodiment, the second drainage hole 1091 is provided with multiple holes.

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

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

[0116] In one embodiment, the first frame assembly 2 and / or the second frame assembly 3 are provided with a mounting bracket 301 on the side 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 through the positioning structure.

[0117] In this embodiment, a positioning structure is provided in the mounting bracket 301 to facilitate the installation and fixation of the voice playback device 5.

[0118] In one specific embodiment, the positioning structure includes a snap fastener, positioning ribs, etc.

[0119] In one embodiment, the first frame assembly 2 and the second frame assembly 3 include a frame body 302 and a housing 303 located on the side of the frame body 302 away from the rotating mechanism 1, with the sound outlet 501 of the voice playback device 5 facing the housing 303.

[0120] In this embodiment, since the sound outlet 501 of the voice playback device 5 faces the housing 303, the sound outlet direction is away from the voice acquisition device 4, which can avoid the secondary transmission of the sound played by the voice playback device 5 to the voice acquisition device 4, and avoid crosstalk and reverberation.

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

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

[0123] like Figure 18 , Figure 18 The arrows in the diagram indicate the direction of the sound output.

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

[0125] In this embodiment, the sound outlet is located in the louver structure 3031, which allows for sound output from multiple positions and a wider sound output range. In addition, the louver structure 3031 can block water flow from outside the housing, preventing water from entering the lower first frame assembly 2 or the second frame assembly 3.

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

[0127] In one embodiment, the mounting bracket 301 includes a first side surface 3011 that is attached to the end of the frame body 302, a top surface 3012, and a second side surface 3013 located on the top surface 3012 near one end of the housing 303. The lower end of the second side surface 3013 forms an opening with the lower end of the second side surface 3013. The top surface 3012 is a slope. The housing 303 is provided with a flow guide rib 3033. The flow guide rib 3033 extends toward the frame body 302 on 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 sloping, the water will not stay on the top surface 3012, but will flow downward along the second side surface 3013. After passing through the guide ribs 3033 extending from the housing 303, the water will flow downward through the flow channel, thus preventing the voice playback device 5 from being submerged in water.

[0129] In one embodiment, the bottom of the housing 303 is provided with a drain hole, and the flow channel is connected to the drain hole.

[0130] In this embodiment, water falling from the mounting bracket 301 flows downward through the flow channel after passing through the guide ribs 3033 extending from the housing 303, and is finally discharged through the drain hole, thus preventing water accumulation inside the first frame assembly 2 and the second frame assembly 3.

[0131] In one specific embodiment, the housing 303 is provided with a heating element support 304. Water falling from the mounting bracket 301 flows downward through the flow guide ribs 3033 extending from the housing 303, and after passing through the flow channel, it is discharged through the drain hole after passing through the heating element support 304.

[0132] In one embodiment, the frame body 302 has multiple ribs inside.

[0133] In this embodiment, since multiple ribs are provided inside the frame body 302, the ribs increase the propagation path of the sound emitted by the voice playback device 5 to the voice acquisition device 4. The ribs can consume the sound energy emitted by the voice playback device 5, avoid secondary transmission of the sound played by the voice playback device 5 to the voice acquisition device 4, avoid crosstalk and reverberation, and thus enable the sound played by the voice playback device 5 to be turned up to the maximum, solving the defects of low playback volume and short transmission distance of playback volume in related technologies.

[0134] like Figure 22 As shown, Figure 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 acquisition device 4, which avoids secondary transmission of the sound played by the voice playback device 5 to the voice acquisition device 4, and avoids crosstalk and reverberation.

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