[0043] The embodiments of the present utility model are described below in conjunction with the drawings, and it should be understood that the embodiments described herein are only for the purpose of description and explanation of the present utility model, and are not intended to limit the present utility model.

[0044] Figure 1 The activity sound structure 100 consistent with some embodiments of the present utility model is shown, wherein the activity sound structure 100 is applied to a pop-up book. The activity sound structure 100 is described below in conjunction with Figure 1 The activity sound structure 100 is described.

[0045] In the present embodiment, the pop-up book includes an inner page 200 and a surface layer page 300, wherein the surface layer page 300 is attached to the surface of the inner page 200, or the surface layer page 300 protrudes from the surface of the inner page 200.

[0046] Referring to Figure 1 , the activity sound structure 100 includes a performance part 110, an activity part 120 and a sound sheet 130 (see Figure 2 ). Among them, the performance part 110 is processed into a preset shape. After the pop-up book is opened, the performance part 110 is attached to the side of the surface layer page 300 away from the inner page 200, or the performance part 110 protrudes from the side of the surface layer page 300 away from the inner page 200. In the present embodiment, the performance part 110 is used to present a preset performance effect to the user, wherein the preset shape of the performance part 110 can be determined according to the design of the pop-up book, for exampleFigure 1 The performance part 110 can be a flat shape or a three-dimensional shape. For example, the performance part 110 and the cover page 300 can have an elastic pad therebetween, or the performance part 110 can include a folded three-dimensional structure, which can be converted to a three-dimensional shape after the pop-up book is opened.

[0047] The movable part 120 has a toothed structure 121. For example, the movable part 120 is substantially flat, and the toothed structure 121 is arranged on the side of the flat shape. The flat shape of the movable part 120 is advantageous to reduce the space occupied by the movable part 120 and simplify the structure of the pop-up book.

[0048] At least a part of the movable part 120 is located on the side of the cover page 300 facing the inner page 200. For example, the movable part 120 is embedded between the cover page 300 and the inner page 200, or a part of the movable part 120 is inserted between the cover page 300 and the inner page 200.

[0049] In some embodiments, the movable part 120 includes an operable movable end, for example, a movable end that can be manually pushed and pulled by a user, which is advantageous to improve the user experience and interaction. In some embodiments, for example Figure 1 As shown in FIG. 1, the cover page 300 includes a first through slot 310, and the movable part 120 is connected to the performance part 110 at the position of the first through slot 310, and the movable part 120 can drive the performance part 110 to move along the direction of the first through slot 310. For example, the user pushes and pulls the movable part 120, and the connection position of the movable part 120 and the performance part 110 is limited within the first through slot 310, and moves along the first through slot 310.

[0050] The sound-producing sheet 130 is located on the side of the cover page 300 facing the inner page 200, and the sound-producing sheet 130 can cooperate with the toothed structure 121. When the movable part 120 drives the performance part 110 to move along the first through slot 310, at least one of the toothed structure 121 or the sound-producing sheet 130 vibrates to produce sound. Specifically, for example, in some embodiments, the sound-producing sheet 130 is clamped by the toothed structure 121, and when the movable part 120 moves, the toothed structure 121 undulates the sound-producing sheet 130, or the toothed structure 121 and the sound-producing sheet 130 collide with each other to produce vibration and sound.

[0051] Preferably, at least one of the movable part 120 or the sound-producing sheet 130 includes an elastic sheet, which not only improves the service life, but also adjusts the sound produced by the toothed structure 121 and the sound-producing sheet 130 to meet the actual needs of different pop-up books. In some embodiments, the elastic sheet includes any one or more of a plastic sheet, a rubber sheet, and a metal sheet.

[0052] This embodiment utilizes physical impact to generate sound, eliminating the need for electronic sound generators. This reduces the number of electronic sound generators in the pop-up book, lowering material costs and manufacturing complexity. Furthermore, in this embodiment, while the display section 110 moves, the toothed mechanism 121 and the sound-generating plate 130 work together to generate sound, synchronizing the sound effect with the image effect. This embodiment has a simple structure, occupies little space, and has minimal impact on the pop-up book.

[0053] See Figure 1 and Figure 2 In some embodiments of this invention, the top layer 300 has a second through slot 320. The end of the movable part 120 away from the display part 110 extends from the location of the second through slot 320 to the side of the top layer 300 away from the inner page 200. The end of the movable part 120 extending from the second through slot 320 can serve as an operating end, for example, by a user pushing or pulling, causing the display part 110 to move along the first through slot 310. In some embodiments, the operating end of the movable part 120 may also extend to other locations, as will be described in subsequent embodiments.

[0054] See Figure 1 According to a preferred embodiment of the present invention, the active sound-generating structure 100 further includes a three-dimensional support portion 140. The three-dimensional support portion 140 is disposed on the side of the top page 300 facing the inner page 200, and after the pop-up book is opened, the three-dimensional support portion 140 can support at least a portion of the top page 300 protruding from the inner page 200 to present a three-dimensional visual effect to the user.

[0055] In this embodiment, the sound-emitting plate 130 is disposed on the three-dimensional support portion 140. The three-dimensional support portion 140 supports the top layer page 300 protruding relative to the inner page 200. At the same time, a portion of the structure in the three-dimensional support portion 140 is not in contact with either the top layer page 300 or the inner page 200, such as the central region of the three-dimensional support portion 140. Disposing the sound-emitting plate 130 on the three-dimensional support portion 140 helps to reduce the risk that the structure of the top layer page 300 or the inner page 200 might suppress the vibration amplitude of the sound-emitting plate 130 and affect the sound output.

[0056] See Figure 1 and Figure 2According to the preferred embodiment of the utility model, the three-dimensional support part 140 comprises a first support sheet 141, a fitting part 142 and a second support sheet 143. The first support sheet 141 is fixedly connected with the surface layer page 300, for example, the first support sheet 141 is fixedly connected with the surface layer page 300 by pasting. The second support sheet 143 is fixedly connected with the surface layer page 300, for example, the second support sheet 143 is fixedly connected with the surface layer page 300 by pasting. The fitting part 142 is fixedly connected with the inner page 200, for example, the fitting part 142 comprises a flat surface and is fixedly connected with the inner page 200 by pasting. In some embodiments, the surface layer page 300, the first support sheet 141, the second support sheet 143, the fitting part 142 and the inner page 200 are of paper structure and can be fixedly connected by pasting.

[0057] The first support sheet 141 and the second support sheet 143 are both connected with the fitting part 142, and preferably, the first support sheet 141 and the second support sheet 143 are respectively located on the opposite sides of the fitting part 142, which is beneficial to improving the structural stability. In addition, the first support sheet 141 and the second support sheet 143 have an inclination angle relative to the inner page 200 to support at least a part of the surface layer page 300 to protrude from the inner page 200. The inclination angle of the first support sheet 141 and the second support sheet 143 relative to the inner page 200 can be determined according to the presentation effect of the three-dimensional book. For example, the first support sheet 141 and the second support sheet 143 are inclined relative to the inner page 200 to form a slope of the surface layer page 300 relative to the inner page 200.

[0058] In some embodiments, in the three-dimensional support part 140, the first support sheet 141 and the second support sheet 143 are both rotatably connected with the fitting part 142. When the three-dimensional book is closed, the first support sheet 141 and the second support sheet 143 are close to the inner page 200 to make the whole three-dimensional book present as a shape of approximately flat plate. When the three-dimensional book is opened, the first support sheet 141 and the second support sheet 143 can be automatically converted (for example, by using a self-compressed elastic member) or manually converted by a user to a three-dimensional shape, so that at least a part of the structure of the surface layer page 300 protrudes from the inner page 200 to form a three-dimensional structure.

[0059] As shown in Figure 2 In some embodiments, the first support sheet 141 has a third through slot 144. The movable part 120 penetrates through the third through slot 144. Preferably, the second through slot 320 in the surface layer page 300 and the third through slot 144 on the first support sheet 141 are aligned, the movable part 120 penetrates through the second through slot 320 and the third through slot 144 in sequence and extends to the position of the first through slot 310 to be connected with the performance part 110.

[0060] As shown in Figure 2As shown, in some embodiments, the sound production sheet 130 is arranged at the position of the third through slot 144. In which, one end of the sound production sheet 130 is fixed at the position of the third through slot 144, and the other end of the sound production sheet 130 is suspended, for example, the end of the sound production sheet 130 suspended has a gap between the first support sheet 141. The tooth structure 121 is towards the sound production sheet 130, and when the movable part 120 drives the performance part 110 to move along the first through slot 310, the tooth structure 121 pokes the end of the sound production sheet 130 suspended, and the sound production sheet 130 vibrates to produce sound.

[0061] According to the preferred embodiments of the utility model, the tooth structure 121 can be arranged to be non-uniform, for example, the tooth structure 121 includes a plurality of sawteeth protruding from the edge of the movable part 120, and the sizes of the plurality of sawteeth are different. When the tooth structure 121 pokes the end of the sound production sheet 130 suspended, the non-uniform sawteeth can provide different sounds, which is beneficial to make the movable sound production structure 100 present more rich sound effects to the user.

[0062] Referring to Figure 2 In the preferred embodiments of the utility model, the movable part 120 includes a first structure sheet 122, a second structure sheet 123 and a connecting part 124. In which, the first structure sheet 122 and the second structure sheet 123 are rotatably connected, and at least part of the structure of the first structure sheet 122 and at least part of the structure of the second structure sheet 123 are arranged symmetrically relative to the connecting position of the second structure sheet and the first structure sheet. The first structure sheet 122 and the second structure sheet 123 can be relatively rotated to overlap, which is beneficial to improve the structural stability of the movable part 120 and prolong the service life of the movable part 120.

[0063] The connecting part 124 is protrusively arranged on the first structure sheet 122 or the second structure sheet 123, and the connecting part 124 is connected with the performance part 110. Specifically, for example, the connecting part 124 can penetrate the first through slot 310 and is fixedly connected with the performance part 110.

[0064] Figure 3 And Figure 4 The movable sound production structure 100 consistent with some other embodiments of the utility model is shown. Referring to Figure 3 In this embodiment, the surface layer page 300 and the inner page 200 are attached, and a cavity 210 is defined between the surface layer page 300 and the inner page 200. In which, the sound production sheet 130 is arranged in the cavity 210. The movable part 120 is arranged between the surface layer page 300 and the inner page 200, and the movable part 120 drives the performance part 110 to move along the direction parallel to the surface layer page 300.

[0065] For example, the cover page 300 and the inner page 200 are glued together. A groove is cut into the inner page 200, and the cover page 300 covers the groove to form a cavity 210. The position of the first through groove 310 corresponds to the position of the cavity 210. In some embodiments, a groove can also be formed on the side of the cover page 300 facing the inner page 200 to cooperate with the inner page 200 to form the cavity 210. Alternatively, in some embodiments, the side of the inner page 200 away from the cover page 300 also has a bottom plate, and the bottom plate, the inner page 200, and the cover page 300 are sequentially attached. The inner page 200 has a through hole, and a cavity is formed at the location of the through hole.

[0066] The movable part 120 can extend from the side of the inner page 200 and the cover page 300 at the bonding position to the outside of the inner page 200 and the cover page 300 to facilitate user operation. Preferably, a notch is provided at the edge of the cover page 300 or the inner page 200, and the movable part 120 extends to the notch without exceeding the edge of the cover page 300 and the inner page 200. This can protect the movable part 120, reduce the risk of damage to the movable part 120 due to external influences, and at the same time, it does not affect user operation.

[0067] See Figure 4 The sound-generating plate 130 includes a gear 131, which is rotatably disposed within the cavity 210 and meshes with the toothed structure 121 of the movable part 120. When the movable part 120 moves, the toothed structure 121 rotates relative to the gear 131 and simultaneously collides with the gear 131 to vibrate and generate sound. In some embodiments, there is a certain amount of play between the toothed structure 121 and the gear 131 to avoid interference that could affect sound generation. In this embodiment, the engagement of the gear 131 with the toothed structure 121 helps to reduce the size of the sound-generating plate 130 in the direction perpendicular to the inner page 200, thereby reducing the thickness of the pop-up book.

[0068] See Figure 4 According to a preferred embodiment of the present invention, the movable part 120 includes a guide part 125, and a guide rail 211 is disposed within the cavity 210. The guide part 125 can move along the guide rail 211 to limit the movement direction of the movable part 120, reduce the risk of lateral compression of the movable part 120, and improve structural stability. Furthermore, at least one of the cavity 210 or the movable part 120 includes a limiting part 212 for limiting the movement range of the movable part 120. For example... Figure 4 As shown, the limiting part 212 can engage with the edge of the toothed structure 121 to prevent the movable part 120 from being pulled out of the cavity 210, thus preventing damage or loss of parts.

[0069] The embodiment of the utility model further includes a three -dimensional book, wherein, including inner page 200, surface layer page 300 and at least one movable sound production structure 100 as described in preceding embodiment. Wherein surface layer page 300 is attached on the surface of inner page 200 or protrudes from the surface of inner page 200. Movable sound production structure 100 can be mutually matched with every inner page 200 and surface layer page 300 in three -dimensional book, also can be set between partial inner page 200 and surface layer page 300 in three -dimensional book.

[0070] In some embodiments, part of electronic sounder can also be set in three -dimensional book as the supplementary equipment of three -dimensional book to present sound effect, make up the sound effect that movable part 120 and sound production sheet 130 can not realize, further improve user experience.

[0071] Finally, it should be noted that: the above only for the embodiment of the utility model, and is not used to limit the utility model, although the utility model has been described in detail with reference to the foregoing embodiments, for the person skilled in the art, it still can modify the technical scheme recorded in preceding each embodiment, or equivalent replacement to part of technical features.
