Pop up greeting card

The invention relates to a stereo greeting card with acousto-optic stage modeling, in particular to a stereo greeting card with acousto-optic stage modeling.

The greeting card, which is a unique gift, can bear the emotion of the owner of the cardholder, and the festival, whether birthday, commemorative day, festival or other special occasions, and can convey the center of the cardholder to the consignee, so that the other party can feel the care and warm.

Greeting cards are developed from traditional planar board chips to a wide variety of stereo-effect greeting cards to meet more demands of people. However, in order to perform deep analysis on existing stereo greeting cards, it is found that there are many disadvantages.

In the existing stereo greeting card, although a product with an acousto-optic effect is also added, the acousto-optic effect can be triggered only by touching the button by a person, so that the best effect can be immediately displayed when the stereo greeting card cannot be opened, and the feeling of the greeting card is insufficient, thereby reducing the effect of the greeting card.

Therefore, the present invention aims to provide a stereoscopic greeting card which is simple in structure, high in reliability and convenient to produce and open, and can automatically display acousto-optic effects to meet market requirements.

Further, an acousto-optic circuit board is arranged in the background wallboard, a trigger switch is automatically triggered when the greeting card is unfolded, and the acousto-optic circuit board emits an acousto-optic effect.

Further, the trigger switch is a magnetically controlled switch, and the triggered magnet sheet is disposed in the foldable movable plate.

Further, the trigger switch is a photoresistor sensor, and the photoresistor sensor is disposed on a central portion of the background wallboard.

Further, the trigger switch is a mechanical switch, and the mechanical switch is disposed between the foldable movable plate and the background wallboard.

Further, the background wallboard is of a double-layer paperboard structure, and an acousto-optic circuit board is built in the background wallboard.

Further, the foldable movable plate is provided with four folding lines in the vertical direction, the plate is divided into a first left plate, a second left plate, a central plate, a first right plate and a second right plate, the central plate is centered and symmetrical left and right, the central plate is bonded and fixed to the background wallboard, the first left plate passes through the left side of the panel frame, the first right plate passes through the right side of the panel frame, the first left plate and the first right plate are fitted with the panel frame, and the first left plate and the first right plate can be pulled to move relative to each other.

Further, the left and right ends of the foldable movable plate are each provided with a handle position.

Further, the panel frame body is a rectangular plate folded along upper and lower edges, adhered at the folded edges, with a central cutout to form an opening, and semicircular cutouts at left and right ends to expose handle positions.

Further, the stage display panel is a plurality of folding plate pieces, and the folding plate pieces arranged on the second left plate piece and the second right plate piece are parallel to the background wallboard.

Compared with the prior art, the present invention has the beneficial effects of providing a POP UP greeting card which is simple in structure, high in reliability, convenient to produce and open, and capable of automatically displaying acousto-optic effects, thereby meeting market requirements.
