This musical birthday card turns a familiar cake-and-candle theme into an interactive product for branded greeting card collections. A layered chocolate cake rises from the blue fireworks background, with “HAPPY BIRTHDAY” lettering built directly into the display. When the card opens, the candle lights up and the birthday music begins. Blowing toward the candle switches off the light and changes the audio to cheering or fireworks sounds. For wholesalers and card brands, this combination of paper engineering, sound and responsive lighting adds a higher-value option to a range of Musical Birthday Cards without making the product difficult for the recipient to use.
HPScard develops the electronic layout and 90-degree paper structure as one complete design. Space for the speaker, battery, music chip, LED and blow sensor is planned around the cake layers, allowing the card to open smoothly and stand securely. This is important when producing Light Up Birthday Cards in volume, because visual appearance alone does not confirm reliable electronic performance. The artwork, audio sequence, sensor position and packaging can therefore be adjusted for different brands, languages and target markets. The same functional concept can also be adapted into other pop up greeting cards for birthday without repeating the existing cake artwork.

The standard folded size is 15 × 20 cm. Custom sizes are available to suit the artwork, electronic layout, envelope and retail packaging.
For a resized version, HPScard will review the available internal space, pop-up height and sensor position before confirming the final dimensions. The card can also be developed around an existing packaging specification supplied by the buyer.
Customization Options
LOGO
Print a logo, product code, copyright notice or distributor information on the card back, envelope, paper sleeve or individual packaging.
CONTENT
Customize the printed greeting, language, music, sound length and the audio played after the candle is blown out. Standard sound options include 15, 20 and 30 seconds, subject to the selected electronic module.
DESIGN
Change the cake artwork, fireworks, colors, typography and decorative details. Customers can submit completed AI or PDF files, 2D artwork, sketches or visual references. HPScard can also develop a new paper structure based on the required theme.
Additional options include paper stock, surface finish, LED color, envelope, barcode label and packaging format.
Electronic Function Configuration
The card’s operating sequence can be configured according to the buyer’s product plan. For this version, opening the card starts the music and illuminates the candle. Airflow detected by the blow sensor then turns off the LED and activates the second sound.
The sensor, speaker and battery must be positioned without affecting the pop-up movement. Before sampling, HPScard reviews the required music length, LED behavior, activation method and audio transition. This coordinated approach helps buyers develop sound greeting cards with a clear and practical function rather than adding separate electronic effects without considering how they work together.
Factory Advantages
HPScard combines graphic design, structural engineering, printing and electronic assembly within one manufacturing system. Buyers can develop original 3D Pop-Up Cards without coordinating separate paper-product and electronic-module suppliers.
BSCI, FSC and ISO 9001 documentation can be discussed according to the order, material and market requirements.
Packaging Options
Standard packing is one card with one envelope in an OPP bag. Other options include paper sleeves, printed bags, barcode labels, warning labels, individual boxes and multi-card sets.
For LED greeting cards, the packaging should protect the pop-up structure and electronic components during transport. Carton quantity and internal protection are confirmed according to the finished size, packing method and shipping requirements.
FAQ
1.Can we supply our own music for the card?
Yes. Please provide the audio file and required playback length. Buyers should ensure they have permission to use any copyrighted music supplied for production.
2.Can the blow sensor be adjusted during sampling?
The sensor position and response can be reviewed during sample development. Final performance depends on the card structure, component layout and required blowing distance.
3.Can several artworks be combined in one order?
Mixed designs need to be evaluated individually. Designs may be easier to combine when they share the same size, structure, electronic program and packaging, but the standard MOQ remains 500 pieces per design.
4.What packaging is suitable for wholesale distribution?
An envelope with an individual bag is the standard option. Paper sleeves, barcode labels or individual boxes can be added according to the sales channel and protection requirements.
5.What should we provide for a quotation?
Please send the quantity, size, artwork or references, required music, lighting sequence, packaging and delivery destination. These details allow us to evaluate both the paper structure and electronic configuration.
