Electronic Birthday Cake

This tool is a browser-based virtual birthday candle-blowing interactive program—no download or installation needed, just open the webpage. It suits two main scenarios: first, on-site offline use—configure the cake scene on a phone or computer, then let the birthday person blow out the candles toward the device's microphone, replacing real candles, safe and fun; second, remote online use—customize an exclusive birthday cake, generate a share link to send to friends, who open the link to directly experience the candle-blowing interaction, delivering a birthday surprise across distances.

Compared to real candles, this electronic candle tool has clear advantages: first, safety—no open flame, no burn or fire risk, safe for the elderly and children; second, eco-friendly—no burning exhaust, no wax pollution, zero consumables and zero waste; third, convenient—no venue or prop limits, usable anytime and anywhere, with remote interaction support; fourth, novel and fun—with built-in fireworks and lighting effects for a stronger atmosphere, while avoiding awkward cake-smashing scenes.

After completing all cake scene configuration, click the share icon at the bottom-right of the interface to copy your exclusive scene link with one click. The link preserves all your custom settings, including cake style, candles, message, sensitivity and more. Friends open the link without re-configuring and go straight into the exclusive birthday scene to blow out candles.

Use the scene's lock feature. When locked, microphone pickup and the blow progress bar are disabled—no external noise or slight airflow will trigger the candles to go out, completely avoiding misoperation. When ready to formally blow, unlock to restore normal blow detection. The locked state shows a dedicated lock icon for clear visibility.

Microphone sensitivity is the blow-detection parameter that adapts to different devices. Due to hardware differences between phone and computer microphones, pickup varies: too-high sensitivity causes slight noise to falsely extinguish candles; too-low sensitivity prevents normal blowing from being detected. We recommend fine-tuning the sensitivity for your device before use for the best blow-detection effect.
