Description

Technical Field

[0001] This utility model relates to the field of smart terminals, specifically to a waterproof smart terminal. Background Technology

[0002] Smart terminals are switches used in buildings, homes, and other settings. They integrate screens, microphones, speakers, buttons, and other functions, enabling features such as intercom and smart home control.

[0003] As core communication devices in outdoor operations and industrial settings, smart terminals are constantly exposed to harsh environments such as heavy rain, sandstorms, and salt spray. Moisture and particulate matter intrusion can easily lead to short circuits, microphone blockage, and speaker failure. In existing technologies, because the sound outlet and speaker are directly opposite each other, preventing water from entering the speaker requires making the sound outlet as small as possible and covering it with structures such as foam, mesh, or steel mesh. However, this structure still allows water to enter the speaker, and once inside, water can accumulate near the speaker, causing damage. Furthermore, when water gets into the foam, mesh, or steel mesh covering the sound outlet, the increased water droplets increase internal damping, altering the sound produced by the speaker.

[0004] The purpose of this invention is to design a waterproof smart terminal to address the problems existing in the prior art. Utility Model Content

[0005] In view of the problems existing in the prior art, the present invention provides a waterproof smart terminal that can effectively solve at least one of the problems existing in the prior art.

[0006] The technical solution of this utility model is:

[0007] A waterproof smart terminal includes a housing, within which a speaker is disposed.

[0008] The housing is provided with a sound outlet corresponding to the position of the speaker, and the sound outlet is offset from the speaker.

[0009] The housing has an inclined water guide groove on one side of the sound outlet, the bottom end of the water guide groove extends to the sound outlet of the speaker, and the top end of the water guide groove connects to the outside of the housing.

[0010] The bottom of the water channel is covered with a speaker waterproof component.

[0011] Furthermore, the water guide channel includes a first slope and a second slope connected in sequence, the starting point of the first slope is located at the sound outlet of the speaker, and the ending point of the second slope is located on the side of the sound outlet.

[0012] Furthermore, the surface of the housing is provided with a water guide platform, which is connected to the top of the water guide groove. The housing is provided with a water guide skirt around the edge of the shape formed by the sound outlet, the water guide groove, and the water guide platform. The end of the water guide skirt away from the sound outlet is set as an opening.

[0013] Furthermore, the housing is provided with a dredging pool on one side of the opening of the water guide skirt, and the bottom surface of the dredging pool is lower than the water guide platform.

[0014] Furthermore, the speaker waterproofing component includes foam and / or mesh fabric.

[0015] Furthermore, the sound outlet is covered with a sound-emitting mesh.

[0016] Furthermore, a microphone is provided inside the housing, and a sound-receiving port is provided in the housing corresponding to the position of the microphone. A sound-receiving cavity is provided below the sound-receiving port in the housing. The bottom of the sound-receiving cavity is connected to the microphone, and a microphone waterproof component is provided on the upper surface of the sound-receiving cavity.

[0017] Furthermore, the housing includes an outer shell and an inner shell, the microphone port is disposed in the outer shell, the microphone cavity is disposed in the inner shell, and the distance between the microphone cavity and the microphone port is set.

[0018] Furthermore, the diameter of the sound-receiving cavity is larger than the diameter of the sound-receiving port, and / or, the bottom end of the sound-receiving cavity narrows and connects to the sound-receiving end of the microphone.

[0019] Furthermore, the microphone waterproofing component includes foam and / or mesh fabric.

[0020] Therefore, this utility model provides the following effects and / or advantages:

[0021] This application extends and shifts the distance between the sound outlet and the speaker by misaligning the sound outlet and the speaker, thereby effectively guiding external water into the water guide channel after it enters through the sound outlet, and quickly guiding it from the water guide channel to the outside of the housing.

[0022] This application avoids the speaker's waterproof component from coming into contact with water, thus preventing excessive damping that could hinder the speaker's sound production, by attaching the waterproof component to the bottom of the water channel.

[0023] This application changes the microphone waterproof component to be located on the upper surface of the sound receiving cavity. At the same time, the sound receiving cavity below the microphone waterproof component can reduce the high-frequency resonance point, so that the high-frequency response is relatively attenuated and the sound curve received by the microphone is smoother.

[0024] Other features and advantages of this invention will be set forth in the description which follows, and will be apparent in part from the description, or may be learned by practicing the invention. The objects and other advantages of the invention are realized and obtained through the structures particularly pointed out in the description and the drawings.

[0025] It should be understood that the above summary and the following detailed description of the present invention are exemplary and explanatory, and are intended to provide further explanation of the present invention as claimed. Attached Figure Description

[0029] Figure 4 This is a schematic diagram of the structure of the present invention after the outer shell is hidden. Detailed Implementation

[0030] To facilitate understanding by those skilled in the art, the structure of this utility model will now be described in further detail with reference to the accompanying drawings:

[0031] Example 1

[0032] refer to Figure 1-4 A waterproof smart terminal includes a housing 1, and a speaker 2 is disposed inside the housing 1;

[0033] The housing 1 is provided with a sound outlet 11 at the position corresponding to the speaker 2, and the sound outlet 11 is offset from the speaker 2;

[0034] The housing 1 is provided with an inclined water guide groove 13 on one side of the sound outlet 11. The bottom end of the water guide groove 13 extends to the sound outlet end of the speaker 2, and the top end of the water guide groove 13 connects to the outside of the housing 1.

[0035] In this embodiment, the sound outlet 11 and the speaker 2 are positioned to the left and right respectively, thus offsetting their arrangement. The top of the water guide channel 13 is located to the right of the sound outlet 11, and the path of the water guide channel 13 is inclined and curved. With this structure, the sound outlet 11 and the sound output end of the speaker 2 are not at the same level. This acoustic cavity design can effectively guide external water entering from the sound outlet 11 into the water guide channel, and quickly guide it from the water guide channel 13 to the outside of the housing 1.

[0036] The bottom of the water channel 13 is covered with a speaker waterproof component 3.

[0037] In this embodiment, the speaker waterproof component 3 is attached to the bottom of the water channel 13, which is in front of the sound output end of the speaker 2. At the same time, the water channel 13 also serves as the structure of the front shell acoustic cavity. Together with the speaker waterproof component 3, it can work with the speaker 2 to generate vibration and produce sound, while ensuring sufficient waterproof performance.

[0038] Furthermore, the water guide channel 13 includes a first slope 131 and a second slope 132 connected in sequence. The starting point of the first slope 131 is located at the sound outlet end of the speaker 2, and the ending point of the second slope 132 is located on the side of the sound outlet 11.

[0039] In this embodiment, the slope structure of the first slope 131 and the second slope 132 allows the distance between the water guide channel 13 and the surface of the shell 1 to gradually decrease, thereby narrowing the water guide channel 13. This allows the incoming liquid to be squeezed through the water guide channel 13 and discharged to the outside of the shell 1. Furthermore, the slope of the second slope 132 is greater than that of the first slope 131, which allows the water guide channel to be narrowed quickly near the top of the water guide channel 13, resulting in better drainage.

[0040] Furthermore, a water guide platform 14 is provided on the surface of the housing 1, the water guide platform 14 is connected to the top of the water guide groove 13, and a water guide skirt 15 is provided around the edge of the shape formed by the sound outlet 11, the water guide groove 13, and the water guide platform 14, and the end of the water guide skirt 15 away from the sound outlet 11 is set as an opening.

[0041] In this embodiment, the water-guiding skirt 15 can prevent water from re-entering other parts of the housing 1 after it is discharged from the water-guiding groove 13, and direct the water out along the direction of the opening.

[0042] Furthermore, the housing 1 is provided with a dredging pool 16 on one side of the opening of the water guide skirt 15, and the bottom surface of the dredging pool 16 is lower than the water guide platform 15.

[0043] In this embodiment, the drainage pool 16 is relatively low, which can accumulate the liquid discharged from the water guide platform 15 and further accelerate its discharge to the outside of the shell 1.

[0044] Furthermore, the speaker waterproof component 3 includes foam and / or mesh fabric.

[0045] In this embodiment, the speaker waterproof component 3 is made of IP65 mesh fabric and EVA foam pad and is attached to the front of the speaker. The foam pad is used for cushioning to prevent the mesh fabric from directly contacting other structures and causing abnormal noise.

[0046] Furthermore, the sound outlet 11 is covered with a sound outlet mesh 17.

[0047] Furthermore, a microphone 4 is provided inside the housing 1, and a sound receiving port 12 is provided in the housing 1 corresponding to the position of the microphone 4. A sound receiving cavity 18 is provided below the sound receiving port 12 in the housing 1. The bottom of the sound receiving cavity 18 is connected to the microphone 4, and a microphone waterproof component 5 is provided on the upper surface of the sound receiving cavity 18.

[0048] In the prior art, the microphone waterproof component 5 is located at the front end of the microphone 4. This structure causes sound loss and affects the volume of the sound received by the microphone 4. Therefore, in this embodiment, the microphone waterproof component 5 is changed to be located on the upper surface of the sound receiving cavity 18. At the same time, the sound receiving cavity 18 below the microphone waterproof component 5 can reduce the high-frequency resonance point, so that the high-frequency response is relatively attenuated, and the sound curve received by the microphone 4 is smoother.

[0049] Furthermore, the housing 1 includes an outer shell and an inner shell, the microphone port 12 is disposed in the outer shell, the microphone cavity 18 is disposed in the inner shell, and the distance between the microphone cavity 18 and the microphone port 12 is set.

[0050] The purpose of this embodiment is to leave a certain space between the outer shell and the inner shell, so that when the microphone 4 is picking up sound, the outer shell and the inner shell do not come into contact and cause abnormal noise. At the same time, it can also ensure that the water in front of the mesh is quickly dispersed and does not accumulate in front of the mesh and the front shell, thereby ensuring that the sound quality of the microphone 4 is not affected.

[0051] Furthermore, the diameter of the sound-receiving cavity 18 is larger than the diameter of the sound-receiving port, and / or, the bottom end of the sound-receiving cavity narrows and connects to the sound-receiving end of the microphone.

[0052] Furthermore, the microphone waterproof component 5 includes foam and / or mesh fabric.

[0053] In this embodiment, the mesh fabric meets IP77 standards, preferably a water-film mesh fabric. The surface layer is a high-density woven fiber material as the base support, the middle layer is a functional water film (such as PU coating, ePTFE expanded polytetrafluoroethylene, or nano-hydrophobic coating), and the bottom layer is a breathable substrate (such as a microporous membrane or hydrophilic membrane) to balance waterproofing and breathability requirements. This mesh fabric can more effectively prevent water from entering.

[0054] A waterproofing experiment was conducted using a waterproof smart terminal provided in this embodiment:

[0055] The water spray test device has the following specifications: nozzle inner diameter 6.3mm, water flow rate: 12.5±0.625L / min14; spray distance: 2.5m~3m, covering all directions of the sample36; test time: spray water for 1 minute per square meter of the outer shell surface, total time ≥3 minutes.

[0056] The experiment showed that no water droplets entered the microphone or speaker.

[0057] Immediately after the experimental test, an aggressive intercom test was conducted, and the volume of the microphone and speaker remained unchanged.
