A revolution in piezo composite materials
Piezo actuators to create audio or haptic feedback on any surface
technology
Introducing Dragonfly™
Dragonfly™ by FLORA is the world’s first, patent-approved, full range (60 – 20 kHz) ultra thin piezo actuator. It can be easily mounted onto any surface to transform it into either a full range speaker or a haptic device with a broad operating frequency range. This makes it a viable alternative to the traditional electrodynamic loudspeaker and haptic technology.
Patent approved.
Problems we solved
Frequency response
Conventional piezo
Piezo actuators have served as alarms and speakers for decades, offering advantages such as a slim profile and low power consumption. Yet, their effectiveness hinges on their capability to reproduce low frequencies. Unfortunately, conventional piezo speakers struggle to produce audio frequencies below 400Hz, leading to minimal or even nonexistent bass output.
Conventional piezo speaker
Dragonfly™
Dragonfly™ is meticulously designed and optimized by top minds in Silicon Valley, employing state-of-the-art DOE and numerical simulation techniques. This effort has resulted in a flat frequency response ranging from 60 to 20 kHz. Furthermore, it provides customization capabilities to adjust the frequency response range and output power to align with the specific needs of any application.

Reliability
Piezo materials are typically brittle and can face reliability challenges stemming from drops, handling, vibration, cyclic use, and environmental stress. To address these concerns, Dragonfly incorporates unique protective layers for full encapsulation. Furthermore, material research and optimization ensures the piezo material remain crack-resistant under its various operating conditions.
Advantages
Redefine the standard
Thanks to its innovative and highly optimized design (patent pending), our patented Dragonfly™ surpasses both conventional electrodynamic (cone) speakers and other piezo speakers in every aspect.
Low profile
Less than 3mm thick, and thus, ideal for applications with space constraint, e.g., TVs, monitors, tablets.
Lightweight
5-10x lighter than the conventional cone speaker making it perfect for aerospace applications.
Efficient
3x lower power consumption than the cone speaker. Ideal for EV and battery powered applications.
Invisible
Enables a seamless and modern interior design by offering hidden speaker applications.
No EMI
Piezo-based technology, no magnet, no coil, resulting in an EMI-free solution
Demo
Dragonfly™ vs. Bose
In this video, it is demonstrated that a piezoelectric speaker including two Dragonfly™ units attached to an unoptimized plastic panel can achieve a comparable level of audio performance to that of a popular electrodynamic Bluetooth speaker. This showcases the impressive capabilities of the Dragonfly™ in delivering high-quality audio output.
Applications
Unlock a world of opportunities
Being ultra thin, lightweight, and efficient, Dragonfly™ audio offers distinct advantages that pave the way for a multitude of potential applications. It provides hardware designers with an exceptional opportunity to create innovative audio solutions that were previously beyond reach.
