Description

Technical Field

[0001] The present invention relates to a 4D display greeting card, and particularly to a three-dimensional greeting card having an acousto-optic stage formation.

Background Art

[0002] As a unique gift, a greeting card can represent the feelings and blessings from the sender's heart. Whether it is a birthday, anniversary, holiday, or any other special day, it can convey the sender's thoughts to the recipient and make the recipient feel care and warmth.

[0003] To meet people's more needs, greeting cards have evolved from the conventional flat pattern plate pieces to various three-dimensional greeting cards with three-dimensional effects. However, through intensive analysis of conventional three-dimensional greeting cards, it has been found that there are still many drawbacks.

[0004] Regarding conventional three-dimensional greeting cards, there are products with added acousto-optic effects, but in all cases, the acousto-optic effect can be triggered by a person touching a button. Thus, the optimal effect cannot be exerted immediately when opened, and the impressive form is insufficient, which reduces the effect of the greeting card.

[0005] Therefore, an object of the present invention is to meet the market needs by providing a three-dimensional greeting card with a simple structure, high reliability, easy production, and capable of automatically displaying an acousto-optic effect in 4D when opened.

Mode for Carrying Out the Invention

[0019] Hereinafter, the technical means of this patent application will be described in more detail while referring to specific embodiments.

[0020] The three-dimensional greeting card shown in FIG. 1, FIG. 2, FIG. 3, FIG. 4, FIG. 5, FIG. 6 or FIG. 7 includes a background wall panel piece 101, a folding movable plate piece 102, a panel frame body 103, and a stage display plate piece 104. The background wall panel piece 101 is a base negative film. The folding movable plate piece 102 is adhered to the central portion AA' plane of the background wall panel piece 101. The left and right ends of the folding movable plate piece 102 penetrate through the panel frame body 103 respectively to form a stage-shaped three-dimensional shape, and the stage display plate piece 104 is fixed in the stage.

[0021] An acoustic optical circuit board 1014 is provided in the background wall panel piece 101, and a magnetic control switch 1011 is provided on the acoustic optical circuit board. When the greeting card is opened, a magnet piece 10221 provided in the folding movable plate piece 102 moves away from the magnetic control switch 1011, triggering the switch, and the acoustic optical circuit board emits an acoustic optical effect.

[0022] As a preferred embodiment, the trigger switch can be changed to a photoreceptor switch 1012 arranged in the central portion of the background wall panel piece 101. When the greeting card is opened or folded, the switch is triggered by the change of the light rays on the photosensitive surface of the photoreceptor, and the acoustic optical circuit board emits an acoustic optical effect.

[0023] In a preferred embodiment, the trigger switch can be replaced with a mechanical switch 1013 located between the foldable movable plate piece 102 and the background wall plate piece 101. When the greeting card is opened or folded, the foldable movable plate piece 102 moves, triggering the mechanical switch 1013, and the acousto-optical circuit board produces an acousto-optical effect.

[0024] The background wall panel 101 has a two-layer cardboard structure with an acoustic-optical circuit board built in, and decorations such as patterns or characters can be printed on the surface of the cardboard.

[0025] The aforementioned foldable movable plate piece 102 is a plate piece with four folding lines in the vertical direction. The plate piece is divided into a first left plate piece 1021, a second left plate piece 1022, a central plate piece 1023, a first right plate piece 1024, and a second right plate piece 1025. It is symmetrical with respect to the central plate piece 1023. The central plate piece is glued and fixed to the background wall plate piece. The second left plate piece 1022 penetrates the left side of the panel frame 103, and the first right plate piece 1024 penetrates the right side of the panel frame 103. The first left plate piece 1021 and the second right plate piece 1025 fit into the panel frame 103 and can be moved by pulling them apart.

[0026] Handles 10211 are provided at both the left and right ends of the aforementioned foldable movable plate piece.

[0027] The panel frame 103 is formed by folding a rectangular plate vertically, then gluing the corresponding sides together, cutting out the central portion to leave it empty, and cutting out semicircular portions 1031 from both the left and right ends.

[0028] The stage display panel 104 consists of multiple molding panels, which cross holes provided in the second left panel and the second right panel, and both the holes and the molding panels are parallel to the background wall panel.

[0029] When in use, as shown in Figures 8, 9, or 10, Figure 8A is a schematic diagram showing the greeting card in a folded and flat state, minimizing the product's volume and making it convenient to transport in an envelope. By pulling the handles 10211 and pulling both sides, the greeting card opens, simultaneously turning on the lights and playing music. Figure 8B is a schematic diagram showing one state during the opening process of the greeting card, and Figure 8C is a schematic diagram showing the fully opened state, where multiple decorative plate pieces, such as balloons, fresh flowers, and cakes, are provided in the center, like a stage.
