[0002] In recent years, electronic devices such as computers, digital cameras, and smart home appliances generally have sound functions. In the housing of an electronic device with a sound function, a sound emitting part such as a speaker and / or a sound receiving part such as a microphone are accommodated as an audio part. Through holes are usually provided at positions corresponding to these audio parts in the housing of the electronic device, and sound is transmitted between the outside of the electronic device and the audio part through the through holes. At the same time, the electronic device can also guide light through the through holes, so that the outside world can observe the operating status of the electronic device through the light state of the through holes. However, existing waterproof, sound-permeable and optically-indicating structures are mostly porous structures, or guide light through light guide columns, which not only easily affects the appearance of the device, but also the guided light area is too large, affecting the user's perception.

[0024] In order to more clearly illustrate the technical solutions of the embodiments of this specification, the following is a brief introduction to the drawings required for the description of the embodiments. Obviously, the drawings described below are only some examples or embodiments of this specification. For ordinary technicians in this field, this specification can also be applied to other similar scenarios based on these drawings without creative work. Unless it is obvious from the language environment or otherwise explained, the same reference numerals in the figures represent the same structure or operation.

[0025] Unless the context clearly indicates an exception, the words "a", "an", "an" and / or "the" do not refer to the singular and may also include the plural. Generally speaking, the terms "include" and "comprise" only indicate the inclusion of the steps and elements that have been clearly identified, and these steps and elements do not constitute an exclusive list. The method or device may also include other steps or elements.

[0026] In order to better achieve the function of waterproof and sound-permeable while further realizing the function of optical indication, some embodiments of this specification provide a structure of waterproof, sound-permeable and optical indication. In some embodiments, the structure can be applied to a variety of devices to adapt to different scenarios or fields. For example, the structure can be applied to indoor ceiling speakers, indoor ceiling lights, etc.

[0027] Figure 1 is a schematic diagram of a waterproof, sound-permeable and optically-indicating structure according to some embodiments of this specification; Figure 2 yes Figure 1 A magnified schematic diagram of center A.

[0028] Some embodiments of this specification provide a waterproof, sound-permeable and optically-indicating structure. Figure 1As shown, a waterproof, sound-permeable and optically indicating structure 100 (hereinafter referred to as structure 100) includes a housing 110, an interlayer assembly 120, a PCB board 130 and at least one indicator light 140, wherein the interlayer assembly 120, the PCB board 130 and the at least one indicator light 140 are all disposed in the housing 110. In some embodiments, the interlayer assembly 120 is located between the housing 110 and the PCB board 130, a first through hole 111 is disposed on the housing 110, and the interlayer assembly 120 covers the first through hole 111. The at least one indicator light 140 is disposed around the central axis of the first through hole 111 on one side of the PCB board 130, and a light beam emitted by the at least one indicator light 140 passes through the interlayer assembly 120 and converges in the first through hole 111.

[0029] The housing 110 is a structure for accommodating and fixing other components of the structure 100. The housing 110 can be designed in a variety of structural shapes, such as a cylindrical shape, a square cylindrical shape, etc. In some embodiments, Figure 1 As shown, the housing 110 has a cavity S, and the partition assembly 120 , the PCB board 130 and at least one indicator light 140 are all disposed in the cavity S of the housing 110 .

[0030] The first through hole 111 refers to a hole structure for realizing optical indication and external (i.e., outside the housing 110) sound transmission. In some embodiments, the first through hole 111 is arranged at the bottom center of the housing 110, and the light or light beam emitted by at least one indicator light 140 can pass through the interlayer component 120 and intersect in the first through hole 111 without being scattered too much. When the user needs to observe the operating status of the equipment or device in the housing 110, the bottom of the housing 110 can be directly viewed. At this time, since the light beam emitted by at least one indicator light 140 intersects in the first through hole 111, the light beam will not be affected by the light in the normally on state, so the user can clearly observe the light beam, thereby understanding the operating status of the equipment or device in the housing 110.

[0031] In some embodiments, the bottom inner surface of the housing 110 is designed as a symmetrical stepped structure, and the barrier assembly 120 can be clamped in the symmetrical stepped structure. It can be understood that the use of such a symmetrical stepped structure is conducive to better restraining and fixing the barrier assembly 120 to ensure the airtightness and waterproof effect of the structure 100.

[0032] It should be noted that the bottom inner surface of the shell 110 may also be designed as any other feasible structural form as long as it can achieve the fixation of the partition assembly 120.

[0033] The interlayer component 120 is a component of the structure 100 that has waterproof function and has both sound and light transmission effects. In some embodiments, the interlayer component 120 can be an integral structure or a structure composed of multiple layers.

[0034] In some embodiments, Figure 1-Figure 2 As shown, the barrier component 120 can be located in the space formed by the symmetrical stepped structure on the bottom inner surface of the housing 110 and the lower surface of the PCB board 130, and the barrier component 120 at least partially covers the first through hole 111. By covering the barrier component 120 on the first through hole 111, it is possible to effectively prevent water vapor or dust outside the housing 110 from entering the interior of the housing 110 while achieving the sound and light transmission effect, thereby ensuring the normal operation of the equipment or components inside the housing 110 and extending its service life.

[0035] PCB (Printed Circuit Board) is a substrate produced by circuit printing technology. PCB 130 can be used to carry various electronic components, so as to realize circuit functions in combination.

[0036] In some embodiments, at least one indicator light 140 may be disposed on the PCB board 130. Figure 1 As shown, at least one indicator light 140 can be arranged around the central axis of the first through hole 111 on the lower surface of the PCB board 130, so that the light beam emitted by it can pass through the barrier component 120 and intersect in the first through hole 111 without being scattered. In some embodiments, the central axis of the first through hole 111 can be Figure 1 This is indicated by the dashed line X shown.

[0037] In some embodiments, a processor (not shown) may also be provided on the PCB board 130. The processor may process data and / or information obtained from other devices or devices. The processor may execute program instructions based on these data, information and / or processing results to perform one or more functions described in this application. In some embodiments, the processor may include one or more sub-processing devices (e.g., a single-core processing device or a multi-core multi-core processing device). As an example only, the processor may include a central processing unit (CPU), a controller, a microcontroller unit, a microprocessor, etc., or any combination thereof.

[0038] In some embodiments, the processor may control the lighting mode of at least one indicator light 140 based on the operating state of the device or component in the housing 110. For example, when the device or component in the housing 110 is in a standby state, the at least one indicator light 140 is controlled to emit red light; for another example, when the device or component in the housing 110 is in a working state, the at least one indicator light 140 is controlled to emit green light.

[0039] In some embodiments, the bottom inner surface of the housing 110 at least partially contacts the lower surface of the PCB board 130 and forms a space for accommodating the barrier assembly 120 .

[0040] In some embodiments, other structures (such as Figure 1 The fixing structure 112 shown in the figure) can be used to limit the displacement of the PCB board 130 in the axial direction along the first through hole 111 to ensure the tight connection between the PCB board 130 and the barrier assembly 120, thereby further improving the waterproof, sound-transmitting and light-transmitting effects of the structure 100. The axial direction of the first through hole 111 is consistent with the central axis direction thereof.

[0041] The indicator light 140 is an optical component that indicates the operating status of a device or an apparatus in the housing 110. Exemplary indicator lights 140 may include LED lights, halogen lights, and the like.

[0042] In some embodiments, the number of indicator lights 140 is not limited, and may be one or more. For example, the number of indicator lights 140 may be 4. In some embodiments, at least one indicator light 140 may be equidistantly arranged on the PCB board 130 around the central axis of the first through hole 111. In other words, the distance between any two adjacent indicator lights 140 around the central axis of the first through hole 111 is equal.

[0043] It should be noted that the at least one indicator light 140 may also be disposed on the PCB board 130 in any other feasible manner, as long as the light beams emitted by the at least one indicator light 140 can converge into the first through hole 111 .

[0044] In some embodiments, the indicator light 140 can indicate the operating status of the device or component in the housing 110 through different lighting modes. For example, when the indicator light 140 emits red light, it indicates that the device or component in the housing 110 is in a standby state; for another example, when the indicator light 140 emits green light, it indicates that the device or component in the housing 110 is in a working state.

[0045] For more information about the waterproof, sound-permeable and optically-indicating structure, please refer to the following text (such as Figure 3 ) in the relevant description.

[0046] In some embodiments of this specification, by adopting an interlayer component and reasonably distributing at least one indicator light to form a waterproof, sound-permeable and optically indicating structure, the structure can not only achieve the effect of waterproof and sound-permeable, but also make the light beam emitted by the indicator light converge in the first through hole on the shell without scattering out of the shell, so that the light beam can only be observed in a specific area outside the shell, thereby effectively avoiding the influence of the light beam on the user (such as affecting the perception, etc.). Moreover, when the user needs to observe the operating status of the device or device in the shell, he can directly check the bottom of the shell. At this time, since the light beam emitted by at least one indicator light intersects in the first through hole, the light beam will not be affected by the light in the normally on state, so the user can observe the light beam more clearly to understand the operating status of the device or device in the shell.

[0047] In some embodiments, Figure 1-Figure 2 As shown, the structure 100 further includes a microphone 150, which is disposed on the other side of the PCB board 130. A third through hole 131 may also be disposed on the PCB board 130, and the third through hole 131 is coaxial with the second through hole 1211 and the first through hole 111, and is connected to the microphone 150. For more information about the second through hole, please refer to the relevant description below.

[0048] The microphone 150 is an energy conversion device that converts sound signals into electrical signals. In some embodiments, the microphone 150 can be disposed at the center of the upper surface of the PCB board 130 and communicated with the third through hole 131 to convert the sound signal into an electrical signal and transmit it to the processor. The processor can process and analyze the electrical signal and then control other devices or components, thereby realizing voice control functions such as real-time voice control.

[0049] The third through hole 131 is a channel for the PCB board 130 to transmit sound to the microphone 150. In some embodiments, the external sound can be transmitted to the microphone 150 via the first through hole 110, the barrier component 120 (such as the second barrier 122 and the second through hole 1211 on the first barrier 121), and the third through hole 131 in sequence.

[0050] In some embodiments of the present specification, by providing a third through hole coaxial with the first through hole and the second through hole, and the third through hole is connected to the microphone, external sound can be transmitted to the microphone more smoothly, so as to better realize voice control functions such as real-time voice control.

[0051] In some embodiments, Figure 1-Figure 2 As shown, the barrier assembly 120 includes a first barrier 121 and a second barrier 122. The first barrier 121 is located between the PCB board 130 and the second barrier 122, and the second barrier 122 is located between the first barrier 121 and the housing 110.

[0052] The second barrier layer 122 refers to a layer structure with good waterproof performance and sound and light transmission effects. In some embodiments, the second barrier layer 122 can be used to cover the first through hole 111 located at the bottom of the housing 110 to prevent water vapor or dust outside the housing 110 from entering the housing 110, thereby ensuring the normal operation of the equipment or devices inside the housing 110 and extending its service life.

[0053] In some embodiments, the second barrier layer 122 is a waterproof, sound-permeable and light-permeable film. Exemplary waterproof, sound-permeable and light-permeable films include ePTFE films, PP spunbond non-woven fabric films, PET / PP composite films, etc. In some embodiments, the second barrier layer 122 can also be made of any other feasible material, which is not limited in this specification.

[0054] The first interlayer 121 refers to a layer structure with good light transmission effect and waterproof and sound transmission effect. In some embodiments, the maximum dimension (such as maximum width) of the first interlayer 121 in the radial direction of the first through hole 111 is greater than the maximum dimension of the second interlayer 122 in the radial direction of the first through hole 111. The maximum dimension (such as maximum height) of the first interlayer 121 in the axial direction of the first through hole 111 is greater than the maximum dimension of the second interlayer 122 in the axial direction of the first through hole 111. The radial direction of the first through hole 111 is perpendicular to the axial direction of the first through hole 111.

[0055] In some embodiments, Figure 1 As shown, the first spacer 121 is provided with a second through hole 1211, and the second through hole 1211 is coaxial with the first through hole 111. The second through hole 1211 is a hole structure of the first spacer 121 for transmitting sound and conducting light beams.

[0056] In some embodiments, Figure 1 As shown, the first interlayer 121 is also provided with at least one arc groove 1212 adapted to the indicator light 140. The arc groove 1212 is a groove structure of the first interlayer 121 for inserting the indicator light 140. In some embodiments, the indicator light 140 is provided in a one-to-one correspondence with the arc groove 1212, and the indicator light 140 is at least partially located in the arc groove 1212.

[0057] In some embodiments, the first interlayer 121 is a light-transmitting silicone pad. Since silicone has the characteristics of being soft and compressible, having good light transmittance, being waterproof, being resistant to high temperatures, and having good chemical stability, the silicone pad is selected as the first interlayer 121, which can not only ensure the light transmittance of the first interlayer 121, but also enable the first interlayer 121 to be fully fitted with the PCB board 130 and the second interlayer 122, so as to better ensure the waterproof and sound-transmitting effects of the structure 100. In some embodiments, the first interlayer 121 can also be made of any other feasible material, such as an acrylic board, a polycarbonate board, etc.

[0058] In some embodiments, in order to prevent the gap between the housing 110, the interlayer assembly 120 and the PCB board 130, so that the external water vapor or dust enters the housing 110, or the sound transmitted from the outside is lost when it is transmitted in the housing 110, so as to ensure the waterproof, sound-transmitting and light-transmitting effect of the structure 100, the PCB board 130, the first interlayer 121, the second interlayer 122 and the housing 110 need to be tightly fitted. As an example only, the lower surface of the second interlayer 122 can be directly bonded to the bottom inner surface of the housing 110, and its upper surface is in contact with the lower surface of the first interlayer 121, and the upper surface of the first interlayer 121 can be provided with a protruding structure, and the lower surface of the PCB board 130 can be provided with a groove structure, and the protruding structure and the groove structure cooperate with each other, so as to achieve a tight connection between the PCB board 130, the first interlayer 121, the second interlayer 122 and the housing 110.

[0059] Factors such as the light transmittance of the light-transmitting silicone pad, the size (such as diameter and height) of the first through hole 111, and the position distribution of the indicator light 140 and its beam angle will affect the actual optical indication effect. For example, if the light transmittance of the light-transmitting silicone pad is poor, the light beam emitted by the indicator light 140 may not pass through the interlayer component 120; for another example, if the beam angle range of the indicator light 140 is too large, the light beam emitted by at least one indicator light 140 may not intersect in the first through hole 111. Based on this, it is necessary to limit or constrain the factors that affect the optical indication effect to ensure that the light beam emitted by at least one indicator light 140 can pass through the interlayer component 120 and intersect in the first through hole 111.

[0060] Transmittance is used to indicate the ability of light or light beams to pass through a medium. It is the percentage of the luminous flux passing through a transparent or translucent body to its incident luminous flux.

[0061] In some embodiments, the light transmittance of the light-transmitting silicone pad can range from 20% to 50%. In some embodiments, the light transmittance of the light-transmitting silicone pad can also range from 30% to 70%. In some embodiments, the light transmittance of the light-transmitting silicone pad can also range from 40% to 90%. For example, the light transmittance of the light-transmitting silicone pad is 40%.

[0062] In some embodiments of the present specification, by controlling the light transmittance of the light-transmitting silicone pad within a preferred range, the light transmittance of the first interlayer can be made more in line with actual needs, so that the light beam emitted by the indicator light can smoothly penetrate the first interlayer.

[0063] In some embodiments, the distance between the central axis of at least one indicator light 140 and the central axis of the first through hole 111 may range from 4.5 mm to 5.5 mm. The distance between the central axis of the indicator light 140 and the central axis of the first through hole 111 refers to the straight-line distance between the central axis of the indicator light 140 and the central axis of the first through hole 111. In some embodiments, the distance between the central axis of the indicator light 140 and the central axis of the first through hole 111 may be 4.5 mm to 5.5 mm. Figure 2 The L shown is used to represent it.

[0064] In some embodiments, the distance between the central axis of the at least one indicator light 140 and the central axis of the first through hole 111 may also range from 3.0 mm to 6.0 mm. In some embodiments, the distance between the central axis of the at least one indicator light 140 and the central axis of the first through hole 111 may also range from 4.0 mm to 10.0 mm. For example, the distance L between the central axis of the at least one indicator light 140 and the central axis of the first through hole 111 is 5.0 mm.

[0065] In some embodiments, the height between the lower surface of at least one indicator light 140 and the lower surface of the barrier assembly 120 may be in the range of 1.0 mm to 1.5 mm. The height between the lower surface of the indicator light 140 and the lower surface of the barrier assembly 120 refers to the dimension between the lower surface of the indicator light 140 and the lower surface of the second barrier 122 in the axial direction of the first through hole 111. In some embodiments, the height between the lower surface of the indicator light 140 and the lower surface of the barrier assembly 120 may be in the range of 1.0 mm to 1.5 mm. Figure 2 The H1 shown is indicated.

[0066] In some embodiments, the height between the lower surface of the at least one indicator light 140 and the lower surface of the barrier assembly 120 may also range from 0.5 mm to 1.5 mm. In some embodiments, the height between the lower surface of the at least one indicator light 140 and the lower surface of the barrier assembly 120 may also range from 1.0 mm to 2.0 mm. For example, the height H1 between the lower surface of the at least one indicator light 140 and the lower surface of the barrier assembly 120 is 1.3 mm.

[0067] In some embodiments of the present specification, by reasonably setting the distance range between the central axis of at least one indicator light and the central axis of the first through hole, as well as the height range between the lower surface of at least one indicator light and the lower surface of the partition assembly, it is possible to make the light beam of the indicator light diverge at a certain angle so that part of the light beam can be better converged in the first through hole, thereby achieving a better optical indication effect.

[0068] Figure 3 is an exemplary schematic diagram of the beam angle of the indicator light according to some embodiments of the present specification.

[0069] The beam angle refers to the range of scattering of the light beam emitted by the light source in space. The beam angle can be used to indicate the degree of diffusion or concentration of the light beam. In some embodiments, the beam angle of the indicator light 140 can be used to indicate the degree of diffusion or concentration of the light beam. Figure 3 The α shown is represented.

[0070] In some embodiments, the beam angle range of at least one indicator light 140 may be 110° to 130°. In some embodiments, the beam angle range of at least one indicator light 140 may also be 90° to 120°. In some embodiments, the beam angle range of at least one indicator light 140 may also be 120° to 150°. For example, the beam angle α of at least one indicator light 140 is 120°.

[0071] In some embodiments of the present specification, by controlling the beam angle of at least one indicator light 140 within a preferred range, and combining the reasonable setting of the distance range between the central axis of at least one indicator light and the central axis of the first through hole, and the height range between the lower surface of at least one indicator light and the lower surface of the partition assembly, at least part of the light beam of at least one indicator light can be converged in the first through hole, while the light is only concentrated near the first through hole and will not be scattered, making it difficult for other areas to observe the light beam, thereby improving the user's viewing experience.

[0072] In some embodiments, the diameter of the first through hole 111 may range from 1.7 mm to 3.0 mm. Figure 2 The D1 shown is indicated.

[0073] In some embodiments, the diameter of the first through hole 111 may also range from 1.4 mm to 1.7 mm. In some embodiments, the diameter of the first through hole 111 may also range from 1.7 mm to 3.0 mm. For example, the diameter D1 of the first through hole 111 is 1.7 mm.

[0074] In some embodiments, the height of the first through hole 111 may range from 1.5 mm to 2.5 mm. Figure 2 The h1 shown is used to represent this.

[0075] In some embodiments, the height of the first through hole 111 may also range from 1.2 mm to 2.0 mm. In some embodiments, the height of the first through hole 111 may also range from 1.8 mm to 3.0 mm. For example, the height h1 of the first through hole 111 is 2.0 mm.

[0076] In some embodiments of the present specification, by controlling the diameter range and height range of the first through hole within a preferred range, the light beam of at least one indicator light can have a better display effect after passing through the first through hole, and can prevent the light beam from scattering to a position other than the direction directly facing the first through hole, thereby affecting the user's perception. For example, when the diameter of the first through hole is too large or the height is too low, the light beam emitted by the indicator light may not converge in the first through hole, but will be directly scattered to other areas outside the housing through the first through hole, thereby causing unnecessary visual interference to the user.

[0077] In some embodiments, the diameter of the third through hole 131 is smaller than the diameter of the first through hole 111, and the diameter of the first through hole 111 is smaller than the diameter of the second through hole 1211. The diameter of the third through hole 131 can be expressed as Figure 2 The D2 shown is indicated.

[0078] In some embodiments, the diameter of the third through hole 131 may range from 0.8 mm to 1.5 mm. In some embodiments, the diameter of the third through hole 131 may also range from 1.0 mm to 2.0 mm. In some embodiments, the diameter of the third through hole 131 may also range from 1.2 mm to 2.5 mm. For example, the diameter of the third through hole 131 is 1.2 mm.

[0079] It is worth noting that the diameter range of the second through hole 1211 is not limited, as long as the diameter of the second through hole 1211 is greater than the diameter of the first through hole 111 and smaller than the maximum dimension of the second barrier layer 122 in the radial direction of the first through hole 111. In this way, the sound and light transmission effects can be better achieved while ensuring the waterproof effect of the structure 100.

[0080] In some embodiments of the present specification, by setting the diameter of the third through hole to be smaller than the diameter of the first through hole, setting the diameter of the first through hole to be smaller than the diameter of the second through hole, and controlling the diameter of the third through hole within a preferred range, the transmission of sound can be made more concentrated to reduce reflection and / or interference of other components on the sound, thereby effectively improving the sound pickup effect of the microphone.

[0081] The basic concepts have been described above. Obviously, for those skilled in the art, the above detailed disclosure is only for example and does not constitute a limitation of this specification. Although not explicitly stated here, those skilled in the art may make various modifications, improvements and corrections to this specification. Such modifications, improvements and corrections are suggested in this specification, so such modifications, improvements and corrections still belong to the spirit and scope of the exemplary embodiments of this specification.
