Greeting Cards With circuitry are Triggered with Reed Sensors

Even amidst the ubiquity of smartphones and digital communication, the timeless tradition of exchanging greeting cards persists as a cherished means of commemorating special occasions and conveying heartfelt sentiments. Whether adorning a gift or delivered by hand, greeting cards continue to evoke joy and connection in the recipient as it has a “retro” feel.

Musical greeting cards serenade recipients with celebratory tunes upon opening. Unlike their traditional counterparts, these feature embedded circuit boards programmed to play a message, melodies or sounds.

This integration of technology adds an interactive dimension to the gifting experience, enhancing the emotional impact of the gesture.

Critical to the functionality of these musical greeting cards is the seamless synchronisation of sound with the act of opening. This is achieved through the strategic placement of ultra-miniature reed switches or tiny magnet sensors within the card, discreetly concealed beneath the paper flap. Upon opening, the movement of a small flat magnet triggers the sensor, initiating the playback of the programmed tune.

Compared to the circuitry responsible for generating musical tones and driving the speaker, the incorporation of reed switches introduces minimal bulk, ensuring the aesthetic integrity of the greeting card remains uncompromised. The versatility of reed switches allows for the utilization of both normally open and normally closed versions, offering flexibility in design and functionality to suit varying preferences and requirements.

In essence, the marriage of traditional sentiment with contemporary technology exemplifies the enduring appeal of greeting cards in our digital age. By seamlessly blending innovation with tradition, musical greeting cards continue to captivate recipients and serve as tangible expressions of affection and celebration in our modern world.
