[0021] Example 1

[0022] The recording shielding device provided in Embodiment 1 of the present invention includes an electronic device placement device, which is used to place one or more electronic devices (such as mobile phones), and the recording shielding device is used to shield the recording of electronic devices placed in the electronic device placement device.

[0023] like Figure 1 As shown, the electronic device placement device includes a first housing 1, and a positioning assembly 2 is provided inside the first housing 1. The positioning assembly 2 includes a plurality of positioning frames 21, and a receiving slot 22 for placing electronic devices is formed between each pair of adjacent positioning frames 21. Each receiving slot 22 is provided with a limiting member 23, and the limiting member 23 has a compressed state and an extended state.

[0024] Using the above scheme, each electronic device can be placed in one of the receiving slots 22. In this embodiment, the compressed state refers to the compression of the limiting member 23 when the electronic device is placed in the receiving slot 22, and the extended state refers to the uncompressed state of the limiting member 23. The limiting member 23 has both compressed and extended states, which can be achieved by its own material properties (e.g., the limiting member 23 is made of an elastic material), or by a corresponding structural design (e.g., the limiting member 23 has hollow structures such as holes). When the electronic device is placed in the receiving slot 22, the limiting member 23 in the compressed state also provides stable protection for the electronic device. When the electronic device is removed from the receiving slot 22, the limiting member 23 returns to its initial extended state.

[0025] The electronic device placement device provided in this embodiment 1 can accommodate multiple electronic devices. Furthermore, because the limiting member 23 is compressible, the accommodating space of the receiving slot 22 can vary accordingly to accommodate electronic devices of different sizes and thicknesses, thereby accommodating a wider variety of electronic devices. In addition, the limiting member 23 can also protect the electronic devices, and placing different electronic devices in different receiving slots 22 also facilitates user retrieval of electronic devices.

[0026] In the specific implementation of this embodiment 1, the limiting member 23 further includes a clamping part 231, which is disposed on the surface of the positioning frame 21, and the clamping part 231 has a compressed state and an extended state.

[0027] Furthermore, such as Figure 1 As shown, in this embodiment 1, the limiting member 23 is a clamping part 231, which is disposed on the surface of the positioning frame 21 facing the receiving groove 22. When the electronic device is placed into the receiving groove 22, the electronic device will directly contact the clamping part 231, and the clamping part 231 will be compressed accordingly according to the thickness of the electronic device until the electronic device is placed into the receiving groove 22. In addition, as Figure 1As shown, for each positioning frame 21, two or more clamping parts 231 can be provided along the second direction on the side facing the receiving groove 22, such as the first clamping part 231A, the second clamping part 231B, or two or more clamping parts 231.

[0028] Furthermore, clamping portions 231 can be provided on each side surface of the receiving groove 22. For example, two adjacent positioning frames 21 may each have a clamping portion 231 on the side facing the same receiving groove 22, and these two clamping portions 231 are arranged opposite to each other along the first direction. In this way, after the electronic device is placed into the receiving groove 22, its two sides will abut against the clamping portions 231 on both sides respectively.

[0029] Furthermore, a clamping part 231 can be provided on each side of the same positioning frame 21 along the first direction. If a row of positioning frames 21 is provided along the first direction, taking one positioning frame 21 (denoted as the first positioning frame 21A) as an example, and the two sides of the first positioning frame 21A are two adjacent receiving slots 22, denoted as the first receiving slot 22A and the second receiving slot 22B respectively, the first positioning frame 21A is provided with clamping parts 231 on both sides, one clamping part 231 faces the first receiving slot 22A, and the other clamping part 231 faces the second receiving slot 22B.

[0030] like Figure 1 As shown, in this embodiment 1, the positioning frame 21 can be a single plate, and each positioning frame 21 is sequentially spaced apart in the first housing 1 along the first direction, with the gap between two adjacent single plates forming a receiving groove 22. Alternatively, the positioning frame 21 can also be an L-shaped positioning plate (that is, the positioning frame 21 includes both vertically arranged vertical single plates and horizontally arranged horizontal single plates, and the vertical single plates are perpendicularly connected to the horizontal single plates), with the gap between any two adjacent L-shaped positioning plates forming a receiving groove 22.

[0031] In the specific implementation process of this embodiment 1, such as Figure 1 As shown, the clamping part 231 has a hollow groove 2311 inside.

[0032] In the specific implementation process of this embodiment 1, such as Figure 1 As shown, the clamping part 231 has multiple protrusions 2312 on the side facing the receiving groove 22.

[0033] Furthermore, the clamping part 231 is provided with a hollow groove 2311, allowing the clamping part 231 to have a certain deformation space, which can adapt to electronic devices of different thicknesses, thereby further demonstrating the compression state and extension state mentioned above. The limiting member 23 can be made of rubber, polyurethane, silicone or other materials.

[0034] It should be noted that the clamping part 231 may not need to be provided with a hollow groove 2311. For example, the clamping part 231 itself has sufficient elasticity, which can also allow electronic devices of different thicknesses and sizes to be placed in the receiving groove 22.

[0035] The protrusion 2312 can be provided on the outer side of the clamping part 231, so that the protrusion 2312 directly contacts the electronic device. Multiple protrusions 2312 are provided on the clamping part 231, which can reduce the contact area between the electronic device and the clamping part 231, reduce friction, and allow the electronic device to slide into the receiving groove 22 by its own gravity. Specifically, the protrusion 2312 can extend vertically.

[0036] Furthermore, the first housing 1 may also be equipped with a light strip (not shown in the figure) and a switch for controlling the light strip (not shown in the figure), which can decorate the electronic device placement device. Handles 7 may also be provided on opposite sides of the first housing 1 for easy handling of the device. The handles may be U-shaped or other shapes for easy gripping by the user.

[0037] The workflow provided in Embodiment 1 of this invention is as follows: Each electronic device is placed in its respective receiving slot 22. When the electronic device is placed in the receiving slot 22, the clamping part 231 is compressed. The hollow slot 2311 provides the clamping part 231 with a larger deformation space, which can accommodate electronic devices of different thicknesses and sizes, and also serves as a buffer. Multiple protrusions 2312 are provided on the clamping part 231, which can reduce the contact area between the electronic device and the clamping part 231, reduce friction, and protect the electronic device in the receiving slot 22. When removing the electronic device, the multiple parallel receiving slots 22 facilitate the user's retrieval of the electronic device, and the electronic device placement device of Embodiment 1 is neat and aesthetically pleasing.

[0038] Example 2

[0039] The difference between Embodiment 2 and Embodiment 1 is that the limiting member 23 in Embodiment 2 further includes a support portion 232 and a first connecting member 233 disposed on the support portion 232. A clamping portion 231 is disposed on the surface of the support portion 232 facing the receiving groove 22. The positioning frame 21 has a through hole 211 communicating with the receiving groove 22, and the positioning frame 21 also has a second connecting member 212. The first connecting member 233 is connected to the second connecting member 212, and the setting portion of the clamping portion 231 protrudes from the through hole 211 and is located within the receiving groove 22, such as... Figure 2 and Figure 3 As shown. With the above solution, during assembly, the support 232 can be inserted into the through hole 211 of the receiving groove 22, and part or all of the clamping part 231 protrudes from the through hole 211 and is located within the receiving groove 22. The first connecting member 233 cooperates with the second connecting member 212 to allow the limiting member 23 to be directly installed and fixed on the first housing 1, simplifying the installation steps.

[0040] In this embodiment 2, the limiting member 23 may include a support portion 232 disposed on one side, or it may include two support portions 232 disposed on both sides of the receiving groove 22 and opposite to each other along the first direction. The support portion 232 is vertically disposed inside the first housing 1. In this embodiment 2, the first connecting member 233 is, for example, a sliding column, and the second connecting member 212 is, for example, a sliding groove, or the first connecting member 233 can be a sliding groove and the second connecting member 212 can be a sliding column. The first connecting member 233 is, for example, disposed at the end of the support portion 232, and the second connecting member 212 is, for example, disposed on the inner sidewall of the positioning frame 21 facing the through hole 211. Thus, during assembly, the first connecting member 233 can slide along the second connecting member 212, and ultimately the limiting member 23 slides into the through hole 211.

[0041] In the specific implementation process of this embodiment 2, such as Figure 3 As shown, for each limiting member 23, the number of support parts 232 can be two. The limiting member 23 also includes a support frame 234, and the two support parts 232 are respectively vertically connected to both ends of the support frame 234. The support parts 232, support frame 234, and clamping parts 231 can all be made of the same material (e.g., silicone) and can be integrally molded.

[0042] The limiting member 23 includes two opposing support portions 232, each with a first connecting member 233, and the two support portions 232 are respectively vertically connected to both ends of the support frame 234. Both the support frame 234 and the support portions 232 can be plate-shaped, and the bottom ends of the two support portions 232 can be vertically connected to both ends of the support frame 234 along a first direction, forming a U-shaped structure. In the specific implementation of this embodiment 2, as... Figure 3 and Figure 4 As shown, furthermore, the receiving grooves 22 are arranged sequentially along the first direction. Among the predetermined number of limiting members 23, the surfaces of the adjacent two support portions 232 of any two adjacent limiting members 23 facing away from the receiving grooves 22 are connected to each other, and the support frames 234 in each limiting member 23 are connected sequentially along the first direction. In addition, the positioning frames 21 are arranged sequentially along the first direction, and the through holes 211 of the positioning frames 21 extend to the bottom of the positioning frames 21.

[0043] The predetermined number of limiting members 23 can be all of them or only some of them. The receiving slots 22 are arranged sequentially along the first direction, making the electronic devices placed in the receiving slots 22 neat and aesthetically pleasing, and ensuring a better fit during placement, while also maximizing the number of electronic devices that can be accommodated. In the predetermined number of limiting members 23, the surfaces of adjacent support portions 232 of any two adjacent limiting members 23 facing away from the receiving slot 22 are interconnected (e.g., the first support portion 232A and the second support portion 232B are connected back-to-back to form a whole, such as...). Figure 3 As shown, the support frames 234 in each limiting member 23 are connected sequentially along the first direction. In other words, these limiting members 23 are connected sequentially and form a whole.

[0044] In this embodiment 2, the various limiting members 23 arranged sequentially along the first direction constitute a row of limiting members, and this row of limiting members can form a whole. Alternatively, there may be two or more rows of limiting members 23 arranged along the first direction. These limiting member groups (such as the first row of limiting member group 23A, the second row of limiting member group 23B) are located at different positions along the second direction, and each row of limiting member groups constitutes a whole. Figure 3 , Figure 4 As shown. In this embodiment, multiple rows of limiting components are provided to improve the placement stability of the electronic device.

[0045] Furthermore, the through hole 211 of the positioning frame 21 extends to the bottom of the positioning frame 21. Therefore, during assembly, the support part 232 can enter the through hole 211 from the bottom of the positioning frame 21 and be inserted upwards, while the clamping part 231 exits from the through hole 211 and is located in the receiving groove 22. Two adjacent support parts 232 can pass through the same through hole 211 of the positioning frame 21. For example, two adjacent support parts 232 can be designated as the first support part 232A and the second support part 232B, respectively, and both the first support part 232A and the second support part 232B pass through the through hole 211 of the second positioning frame 21B. Furthermore, only one second connecting member 212 can be provided in the same through hole 211 of the positioning frame 21, and two adjacent support parts 232 can share the same first connecting member 233 or two first connecting members 233 can form a single connecting member, thereby cooperating with the second connecting member 212 in the corresponding positioning frame 21. Alternatively, only two second connectors 212 may be provided in the through hole 211 of the same positioning frame 21, and the first connectors 233 of the two adjacent support parts 232 may be connected to the corresponding second connectors 212 in the corresponding positioning frame 21.

[0046] In this embodiment, assuming the first connector 233 is a sliding column and the second connector 212 is a sliding groove, during assembly, a row of limiting components is inserted upward from the bottom of the positioning frame 21. With the cooperation of the first connector 233 and the second connector 212, the row of limiting components can be quickly installed in the electronic device, simplifying the installation steps and improving assembly efficiency.

[0047] Furthermore, such as Figure 4 As shown, holes are provided at the bottom of the receiving groove 22 and at corresponding positions of the support frame 234. The support frame 234 can be fixed to the first housing 1 by means of connection and fixing, such as screws, bolts, or other fixing methods, to prevent the limiting member 23 from shaking when the electronic device is placed in.

[0048] The principle of the electronic device placement device provided in Embodiment 2 of the present invention is as follows: the support frame 234 in each limiting member 23 is connected sequentially along the first direction, and each limiting member 23 forms an integral whole, which is one or more rows of limiting members. During assembly, the support part 232 is inserted into the through hole 211 at the bottom of the positioning frame 21, and then the clamping part 231 passes through the through hole 211. Multiple rows of limiting members can be installed as needed. For this electronic device placement device, the electronic device can be placed in the receiving slot 22. When the electronic device is placed in the receiving slot 22, the clamping part 231 is compressed. The hollow slot 2311 allows the clamping part 231 to have a larger deformation space, which can adapt to electronic devices of different thicknesses and sizes, and also plays a buffering role. Multiple protrusions 2312 are provided on the clamping part 231, which can reduce the contact area between the electronic device and the clamping part 231, reduce friction, and protect the electronic device in the receiving slot 22. When taking out the electronic device, the multiple parallel receiving slots 22 make it convenient for the user to find the electronic device. Moreover, the electronic device placement device of this embodiment 1 is neat and beautiful.

[0049] Example 3

[0050] The recording shielding device of Embodiment 3 of the present invention includes the electronic device placement device and the interference device as described in Embodiment 1 or Embodiment 2, such as... Figures 5-7 As shown, the jamming device is used to transmit jamming signals into the first housing 1.

[0051] Using the above technical solution, the interference device emits ultrasonic interference signals into the first housing 1. By utilizing the principle of sound masking, it can interfere with the microphone input of the recording equipment, prevent acoustic information from being received by the electronic device, and thus achieve the recording shielding effect.

[0052] In the specific implementation process of this embodiment 3, such as Figure 5As shown, the recording shielding device also includes a second housing 6, a first housing 1 installed inside the second housing 6, an interference device located between the first housing 1 and the second housing 6, and a notch 11 provided at the position opposite to the interference device in the first housing 1.

[0053] Furthermore, such as Figure 6 As shown, the interference device may include an ultrasonic device board 4. If the electronic device is placed in the receiving slot 22 along the second direction, the ultrasonic device board 4 can be disposed on both sides of the first housing 1 along the second direction, so that the ultrasonic waves can effectively act on the earpiece and microphone of the electronic device.

[0054] Furthermore, a notch 11 is provided at the position opposite to the ultrasonic device plate 4 in the first housing 1 to allow ultrasonic signals to pass through. Further, a mesh cover 12 covers the notch 11 for some concealment. In conventional solutions, multiple small holes need to be made in the housing to allow ultrasonic interference signals to pass through, but this results in many burrs, i.e., weld lines, affecting the actual user experience, and also increases mold costs. In this embodiment 3, to overcome the above problems, a notch 11 is provided at the position opposite to the interference device in the first housing 1, and the notch 11 is covered by a mesh cover 12 to allow ultrasonic signals to pass through. The holes on the mesh cover 12 not only ensure that the interference signals emitted by the interference device pass through smoothly, but also enhance the actual user experience and reduce mold costs. The small holes on the mesh cover 12 are circular, but in other embodiments they can also be triangular, rhomboid, or other shapes, which are not limited here.

[0055] In addition, such as Figure 6 As shown, the first housing 1 also includes a main control board 5 and a power supply (not shown in the figure). Both the main control board 5 and the ultrasonic device board 4 are connected to the power supply. The main control board 5 controls the emission of the ultrasonic device board 4. Figure 5 As shown, the first housing 1 is also equipped with a knob 8 for controlling the switch of the ultrasonic device board 4.

[0056] Furthermore, such as Figures 5 to 7 As shown, the recording shielding device also includes a bottom shell 3. A second shell 6 is fitted over the first shell 1, and the first shell 1 is connected to the bottom shell 3. The bottom shell 3 has a connecting part 32. In this embodiment 3, the connecting part 32 can be a positioning post, screw, bolt, or other component that serves a fixing function. Correspondingly, the first shell 1 has a connecting mating part 13, which can be a positioning groove, hole, bolt, screw, or other component to mate with the connecting part 32.

[0057] Furthermore, a gasket 31 is provided at the contact point between the bottom shell 3 and the first shell 1. The gasket 31 is made of rubber, silicone, or other elastic materials and works in conjunction with the receiving groove 22 to place electronic devices while also serving as a buffer. In this embodiment 3, the gasket 31 is also textured. The light emitted by the light strip of the electronic device placement device in embodiment 1 or embodiment 2 is diffused through the reflective texture on the gasket 31 during use, enhancing the ambiance.

[0058] In addition, the inner side of the second housing 6 is provided with multiple positioning grooves 61, and the outer side of the first housing 1 is provided with multiple positioning posts 14. The positioning posts 14 can slide along the positioning grooves 61. Therefore, through the sliding cooperation between the positioning grooves 61 and the positioning posts 14, the second housing 6 can be fitted onto the outer side of the first housing 1.

[0059] The workflow provided in Embodiment 3 of the present invention is as follows: The ultrasonic device board 4 in the interference device emits an ultrasonic interference signal into the first housing 1. The ultrasonic interference signal interferes with the electronic device in the electronic device placement device through the gap 11 covered by the mesh cover 12. The electronic device is placed in the receiving slot 22. The pad 31 can buffer the electronic device. The light emitted by the light strip of the electronic device placement device is turned on and diffused through the reflective texture on the pad 31 during use, which enhances the atmosphere.

[0060] In summary, the electronic device placement device of the present invention can accommodate multiple electronic devices, and the limiting member 23 can be applied to electronic devices of different sizes and thicknesses. It can also protect the electronic devices and facilitate users in finding them. The recording shielding device of the electronic device placement device can shield the electronic devices placed therein, preventing the acoustic information from being clearly received by portable devices.

[0061] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0062] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
