These drawings and textual descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concepts of this application to those skilled in the art through reference to specific embodiments. Detailed Implementation

[0030] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0031] It should be noted that, in this document, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element. Furthermore, components, features, and elements with the same names in different embodiments of this application may have the same meaning or different meanings, the specific meaning of which must be determined by its interpretation in that specific embodiment or further in conjunction with the context of that specific embodiment.

[0032] It should be understood that although the terms first, second, third, etc., may be used herein to describe various information, such information should not be limited to these terms. These terms are used only to distinguish information of the same type from one another. For example, without departing from the scope of this document, first information may also be referred to as second information, and similarly, second information may also be referred to as first information. Depending on the context, the word "if," as used herein, can be interpreted as "when," "when," or "in response to determination." Furthermore, as used herein, the singular forms "a," "an," and "the" are intended to also include the plural forms unless the context indicates otherwise. It should be further understood that the terms "comprising," "including," indicate the presence of the stated feature, step, operation, element, component, item, kind, and / or group, but do not exclude the presence, occurrence, or addition of one or more other features, steps, operations, elements, components, items, kinds, and / or groups. The terms "or" and "and / or" as used herein are to be interpreted as inclusive, or mean any one or any combination thereof. Therefore, "A, B, or C" or "A, B, and / or C" means "any one of the following: A; B; C; A and B; A and C; B and C; A, B, and C."

Furthermore, if the component is flipped, the layer or region will be located "below" or "under" another layer or region. In embodiments of this application, "B corresponding to A" means that B is associated with A, and B can be determined based on A. However, it should also be understood that determining B based on A does not mean determining B solely based on A; B can also be determined based on A and / or other information.

[0033] It should be understood that the specific embodiments described herein are merely illustrative of this application and are not intended to limit this application.

[0034] In the following description, the use of suffixes such as "module," "part," or "unit" to denote elements is solely for the purpose of illustrative purposes and has no specific meaning in itself. Therefore, "module," "part," or "unit" may be used interchangeably.

[0035] The applicant found that packaging boxes typically only have basic packaging functions, and after opening, their subsequent use generally falls into three categories. Many packaging boxes are for single use only; once opened, they are discarded as packaging waste, potentially causing environmental pollution or resource waste. Some packaging boxes are also for single use; although discarded after opening, their materials are recycled, but this still causes some pollution and resource waste. A third type of packaging box can be reused, but it is primarily used for packaging, thus limiting its reusability.

[0036] Based on the above analysis, the applicant proposes a packaging box with a supporting portion at the first opening edge of the lid and an external connecting portion on the second wall of the box body. In a first state, the box body and lid are inserted together to form a box structure with a cavity for accommodating the packaged object, thereby realizing the packaging function of the packaging box. In a second state, the supporting portion of the lid is coupled to the second wall of the box body, with the lid serving as a support for the box body and simultaneously connecting the external connecting portion to an audio playback device. Since the box body extends along a second axis, it forms a cylindrical structure that stably supports the lid, enabling the box body to amplify the sound emitted by the audio playback device, thereby realizing the amplification function of the packaging box.

[0037] First Embodiment

[0038] Figure 1 This is a schematic diagram of the packaging box in the first state according to the first embodiment of this application. Figure 2 This is a schematic diagram of the packaging box of the first embodiment of this application in a second state. Figure 3 This is a schematic diagram illustrating the use of the packaging box of the first embodiment of this application in a second state.

[0039] Please see Figure 1 , Figure 2 and Figure 3As shown, this application embodiment provides a packaging box, including: a box cover 1 having a first axis A1, including a first opening 12 and a first wall portion 11, the first opening 12 being located at one end of the box cover 1 along the first axis A1, and the first wall portion 11 including a support portion 111 near the edge of the first opening 12; a box body 2 having a second axis A2, the box body 2 including a second opening 22 and a second wall portion 21, the second opening 22 being located at the end of the second wall portion 21 along the second axis A2; the second wall portion 21 including an external connection portion 211. The packaging box also includes a first state and a second state. In the first state, the box cover 1 is inserted into the box body 2, and at least a portion of the first opening 12 and at least a portion of the second opening 22 are connected; in the second state, at least a portion of the support portion 111 is coupled to at least a portion of the second wall portion 21, and the external connection portion 211 is used to connect an audio playback device 3.

[0040] Box 2, as one of the main components of the packaging box in this embodiment, has an internal space for accommodating the packaged object. In the first state, the lid 1 and the box 2 are inserted together to form a whole with an internal space, enabling the packaging box in the first state to package the packaged object.

[0041] The lid 1 has a first axis A1, and a first wall portion 11 extends along the first axis A1, forming a first opening 12 at the end of the first axis A1. The lid 1 is inserted into the box body 2 through the first opening 12. The box body 2 has a second axis A2, and a second wall portion 21 extends along the second axis A2, forming a second opening 22 at the end of the second axis A2, thus forming a cylindrical structure. The packaged object can be placed inside the box body 2 through the first opening 12. When the box body 2 is inserted into the lid 1, the first opening 12 is closed by the lid 1 until at least a portion of the first opening 12 and at least a portion of the second opening 22 are connected, at which point the lid 1 and the box body 2 are fully inserted, completing the packaging of the packaged object.

[0042] The support portion 111, located at the edge of the first wall portion 11 near the first opening 12, supports the box body 2 in the second state. When the packaging box is opened, the packaged object has been removed from the box body 2, at which point the box body 2 and the lid 1 separate again. The packaging box is reused by placing it in the second state. In the second state, the support portion 111 of the lid 1 is coupled to the second wall portion 21 of the box body 2, forming a cylindrical structure supported by the lid 1. When an external audio playback device 3 is connected to the external connection portion 211 of the second wall portion 21, the sound emitted by the audio playback device 3 can be amplified through the cylindrical structure formed by the box body 2, thus giving the packaging box a sound amplification function in the second state. Because the box body 2 forms a cylindrical structure, it can also enhance the bass effect of the audio playback device 3 to a certain extent.

[0043] Furthermore, when the packaging box in the second state is not needed as a loudspeaker, the box body 2 and lid 1 can be separated again, the packaged object placed inside the box body 2, and then the box body 2 and lid 1 can be inserted again, returning the packaging box to the first state, accommodating the packaged object. Therefore, the packaging box of this embodiment can switch back and forth between the first and second states, enabling it to meet both the packaging needs of accommodating the packaged object and the amplification needs of the audio playback device 3. This increases the usage scenarios of the packaging box, enhances its reuse value, and is also beneficial to environmental protection. Simultaneously, the switching between the first and second states of the packaging box in this embodiment is simple and somewhat fun.

[0044] Further reading Figure 1 and Figure 2 The box body 2 also includes an inner box 23, and a second wall portion 21 is fitted onto the outside of the inner box 23; in the first state, the inner box 23 is inserted into the first wall portion 11, the first wall portion 11 abuts against the second wall portion 21, and the first axis A1 coincides with the second axis A2.

[0045] The inner box 23 is the main component for holding the packaged object. The second wall portion 21 is fitted onto the outside of the inner box 23, thereby protecting the inner box 23 and the packaged object. In the first state, the first wall portion 11 of the lid 1 is fitted onto the outside of the inner box 23, thereby achieving the insertion between the inner box 23 and the lid 1. When the first wall portion 11 and the second wall portion 21 abut, it indicates that the inner box 23 and the lid 1 are fully inserted, that is, the box body 2 and the lid 1 are fully inserted. The first axis A1 and the second axis A2 coincide, so that the box body 2 and the lid 1 can form a whole extending in the same direction, thereby making the packaging box of this embodiment more aesthetically pleasing.

[0046] Further reading Figure 1 Both the first wall portion 11 and the second wall portion 21 are cylindrical surfaces, and their outer diameters are equal. In the first state, after the box body 2 and the box lid 1 are inserted, the first wall portion 11 and the second wall portion 21 can form a cylindrical whole, making the packaging box of this embodiment more aesthetically pleasing. Furthermore, the first opening 12 or the second opening 22 is less likely to snag on the outside, preventing accidental opening of the packaging box and improving the packaging box's protective ability for the packaged object. In addition, in the second state, the cylindrical second wall portion 21 is more conducive to sound reflection within the box body 2, thus further improving the sound amplification effect of the packaging box of this embodiment.

[0047] Figure 4 This is a schematic diagram of the structure of the packaging box after the lid and body are separated, according to the first embodiment of this application. Figure 5This is a schematic diagram of another structure of the packaging box after the lid and body of the packaging box are separated, according to the first embodiment of this application.

[0048] Further, please refer to Figure 4 and Figure 5 The outer portion 211 includes a fixed opening 212 that penetrates the second wall portion 21; the inner box 23 moves relative to the second wall portion 21 along the second axis A2; in a first state, the inner box 23 blocks the inner side of the fixed opening 212; in a second state, the inner box 23 moves along the second axis A2 so that the fixed opening 212 connects the inner side and the outer side of the second wall portion 21.

[0049] The external part 211 connects to the external audio playback device 3 through the fixed opening 212. It should be noted that when the audio playback device 3 is connected to the fixed opening 212, it is only necessary to insert the audio output device of the audio playback device 3 into the fixed opening 212 and then lock the audio playback device 3 into place. At this time, the sound emitted by the audio playback device 3 will directly propagate along the second axis A2 towards the second opening 22 inside the box 2. Simultaneously, the box 2 resonates, amplifying the sound intensity and achieving amplification. In the first state, the audio playback device 3 does not need to be connected to the fixed opening 212. The inner box 23 covers the inside of the fixed opening 212, allowing the inner box 23 to fully utilize the internal space of the second wall 21. This allows the packaging box of this embodiment to accommodate a larger packaged object in the first state, avoiding resource waste caused by over-packaging. In the second state, the fixed opening 212 needs to be connected to the audio playback device 3. The inner box 23 can be moved along the second axis A2 so that the fixed opening 212 connects the inner and outer sides of the second wall 21, thereby avoiding the inner box 23 interfering with the connection between the fixed opening 212 and the audio playback device 3.

[0050] Further reading Figure 4 The first wall portion 11 and the support portion 111 are reused; the edge of the first opening 12 is provided with at least one support notch 112. In the second state, the support notch 112 is coupled to at least a portion of the second wall portion 21. Since the first wall portion 11 and the support portion 111 are reused, the outer surface of the first wall portion 11 can form a whole, and there will be no protrusion or depression due to the provision of the support portion 111, thereby making the packaging box of this embodiment more aesthetically pleasing. The support notch 112 at the edge of the first opening 12 enhances the coupling effect between the support portion 111 and the second wall portion 21, making the support of the lid 1 on the box body 2 more stable in the second state. For example, when the second wall portion 21 is a cylindrical surface, the support notch 112 can be an arc-shaped notch to reduce the risk of the box body 2 rolling off the lid 1.

[0051] Further reading Figure 4The number of support notches 112 is at least two, and the at least two support notches 112 are coaxially arranged, with their axes inclined relative to the first axis A1. By setting at least two coaxial support notches 112, the support of the lid 1 on the box body 2 is made more stable. In the second state, the lid 1 supports the box body 2 through the support notches 112, so that the second axis A2 of the box body 2 is parallel to the axis of the support notches 112. Since the axes of at least two support notches 112 are inclined relative to the first axis A1, the second axis A2 is also inclined relative to the first axis A1. By adjusting the direction of the axis of the support notches 112, the orientation of the box body 2 in the second state can be adjusted, thereby adjusting the sound emission direction of the amplification.

[0052] Further reading Figure 4 The lid 1 also includes a support surface S, which is the end face of the lid 1 facing away from the first opening 12. The support surface S intersects with the first axis A1. In the second state, the lid 1 is placed upside down on a stable surface, and the support surface S is in contact with the stable surface on which the lid 1 is placed, thereby keeping the upside-down lid 1 stable, and thus keeping the box body 2 stable. Since the support surface S provides more stable support for the lid 1 compared to the first axis A1, the stable surface provides more stable support. For example, the first axis A1 can be perpendicular to the support surface S. When the stable surface is in contact with a horizontal surface, the support surface S is in contact with the horizontal surface, so the support surface S also remains horizontal. The first axis A1 is a vertical axis, allowing the lid 1 to stably support the box body 2. At this time, the second axis A2 of the box body 2 can be tilted relative to the first axis A1, supporting the notch 112, so that the second axis A2 is tilted relative to both the horizontal and vertical directions, which facilitates the connection between the audio playback device 3 and the box body 2, and also allows the amplified sound to propagate in a direction away from the horizontal plane, increasing the coverage of the amplified sound, thereby improving the amplification effect of the packaging box in the second state of this application embodiment.

[0053] Figure 6 This is a schematic diagram of another structure of the packaging box after the lid and body of the packaging box are separated, according to the first embodiment of this application. Figure 7 This is a schematic diagram of the structure of the packaging box according to the first embodiment of this application, when the tear-off portion of the box lid is torn open after it is separated from the box body.

[0054] Further, please refer to Figure 6 and Figure 7 The external portion 211 also includes a tearing portion 213, which is located at the fixed opening 212. In the first state, the tearing portion 213 and the second wall portion 21 are an integral structure. In the second state, the tearing portion 213 is torn open to expose the fixed opening 212.

[0055] Upon first use, the packaging box of this embodiment is primarily used to hold the packaged object, and therefore will initially be in the first state. At this time, considering that the packaged object is typically a commodity, the packaging box should not have been opened. The tearing part 213 of the outer portion 211 is located at the fixed opening 212. When the packaging box is in the first state and has not entered the second state, the tearing part 213 and the second wall portion 21 are an integral structure, making the external structure of the box body 2 a whole. This not only gives the box body 2 good structural strength but also makes the box body 2 more aesthetically pleasing. When the packaging box is opened and the packaged object is removed, and the packaging box of this embodiment is used as a sound amplification device, the packaging box is in the second state. The tearing part 213 is torn open to form the fixed opening 212, facilitating the connection of the audio playback device 3 to the fixed opening 212.

[0056] Further reading Figure 6 and Figure 7 The fixed opening 212 extends circumferentially along the second wall portion 21, and both end sidewalls of the fixed opening 212 along the second axis A2 are perpendicular to the second axis A2. The second wall portion 21 extends along the second axis A2 to form a cylindrical shape, and the fixed opening 212 extends circumferentially along the second wall portion 21, with both end sidewalls along the second axis A2 being perpendicular to the second axis A2, thus forming an elongated opening. When the audio playback device 3 is connected to the fixed opening 212, the audio playback device 3 can be inserted into the fixed opening 212, and the sidewalls of the fixed opening 212 at both ends along the second axis A2 can support and fix the audio playback device 3. For example, the audio playback device 3 can be a smart mobile terminal, such as a mobile phone or tablet computer.

[0057] Figure 8 This is a schematic diagram illustrating another use of the packaging box of the first embodiment of this application in a second state.

[0058] Further, please refer to Figure 8 The inner box 23 protrudes at least partially from the second opening 22. The inner box 23 moves relative to the second wall portion 21 along the second axis A2 to adjust the length of the inner box 23 protruding from the second opening 22. The inner box 23 and the second wall portion 21 are fixed in relative position by friction.

[0059] The inner box 23 protrudes from the second opening 22, facilitating insertion with the lid 1. In the first state, simply inserting the inner box 23 into the lid 1 achieves the connection between the box body 2 and the lid 1, providing effective protection for the packaged object. The inner box 23 can move relative to the second wall 21 along the second axis A2, thereby adjusting the length of the inner box 23 extending from the second opening 22. In the second state, the packaging box is used for sound amplification. The amplification effect is related to the sum of the length of the inner box 23 extending from the second opening 22 and the distance from the fixed opening 212 to the second opening 22. Therefore, adjusting the length of the inner box 23 extending from the second opening 22 can adjust the sound amplification effect of the packaging box in the second state of this embodiment. When the length of the inner box 23 extending from the second opening 22 is longer, the sound amplification effect of the packaging box in this embodiment is stronger, and the bass amplification effect is better.

[0060] In summary, the packaging box provided in this application embodiment, in its first state, has its lid and body inserted to form a packaging box for containing packaged objects; in its second state, the supporting part of the lid couples with the second wall of the body, causing the body to form a cylindrical structure. When an audio playback device is connected to the external part of the body, the cylindrical body can be used for amplification of the audio playback device. This application embodiment improves the applicability of the packaging box by offering different functions in the first and second states, enhancing its reuse value and contributing to environmental protection.

[0061] The above are merely preferred embodiments of this application and do not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
