# xMEMS Introduces Sycamore: An Innovative 1mm Full-Range Near-Field Micro Speaker
Innovation in the audio sector is nothing new, and xMEMS leads this charge with its newest offering, the **Sycamore** micro speaker. This advanced, solid-state audio driver is crafted to provide premium sound within a unit that measures only **1.13mm in thickness** and weighs a light **150mg**. The Sycamore is set to create a stir in the realm of **earbuds**, **XR glasses**, and **smartwatches**, bringing forth an unprecedented standard of performance and adaptability in design.
## The Transformation of Solid-State Audio
Classic audio drivers commonly used in earbuds and speakers depend on magnetic coils for sound production. In contrast, xMEMS is redefining audio technology by implementing **silicon-based alternatives**. These solid-state drivers leverage **piezoelectric technology** paired with **ultra-thin membranes** to generate sound. This transition from traditional magnetic drivers to piezoelectric options is not only groundbreaking but also paves the way for enhanced miniaturization and performance benefits.
The Sycamore expands upon xMEMS’ previous success with the **Cypress driver**, already integrated into various in-ear earbuds, including the **Creative Aurvana Ace 2**. While the Cypress was tailored for in-ear settings, the Sycamore targets the **open-ear market**, making it perfect for devices such as **open-ear earbuds**, **XR glasses**, and **smartwatches**.
## A Compact Powerhouse: The Sycamore’s Features and Design
The Sycamore micro speaker is a feat of engineering. Measuring merely **1.13mm thick**, it is **three times thinner** than traditional drivers and **one-seventh the size**. This remarkably small design enables manufacturers to create lighter, more compact devices or utilize additional space for other elements, like larger batteries.
In a discussion with **Mike Housholder**, VP of Marketing and Business Development at xMEMS, he emphasized that the Sycamore signifies the “maturation” of the company’s **ultrasonic transducer technology**. Advancements in **MEMS (Micro-Electro-Mechanical Systems) architecture** have facilitated the shift from in-ear applications to open-air use, establishing the Sycamore as a versatile option for numerous devices.
### Sound Quality: Excelling in Its Class
In spite of its small stature, the Sycamore produces remarkable sound quality. A significant challenge for micro speakers is sustaining strong **low-frequency performance**, especially in the **bass** spectrum. Housholder noted that xMEMS’ **ultrasonic, modulated air pulse generation technology** provides a **first-order low-frequency degradation**, allowing for a more gradual drop in bass performance compared to standard dynamic drivers which display a sharper, second-order decline.
Consequently, the Sycamore can achieve **mid-bass performance** on par with typical drivers, delivering up to **11dB of headroom** in the **sub-bass extension**. This positions it as a formidable option for high-quality audio devices, despite its petite size.
### Resilience and Design Adaptability
The Sycamore is also equipped with an **IP58 ingress protection rating**, ensuring it is resistant to dust and moisture. This level of robustness is essential for **active earbuds** and other wearable gadgets exposed to various conditions.
Another benefit of the Sycamore’s design is its **rigid silicon diaphragm**, which eliminates the necessity for intricate shell designs usually required to manage back volume in conventional drivers. This streamlines the production process for audio brands and enhances flexibility in the overall device design.
## The Future of Audio: Upcoming Developments for Sycamore
The Sycamore is on track to debut in consumer products soon. Housholder stated that xMEMS plans to unveil prototypes of devices featuring the Sycamore at **CES 2025**, with **mass production** anticipated to start in **Q4 2025**. The initial consumer products incorporating the Sycamore are expected to reach the market in **2026**.
Given the success of xMEMS’ previous drivers, the Sycamore is likely to be embraced by both manufacturers and consumers. Its adaptability, compact design, and remarkable sound quality render it an outstanding choice for a broad spectrum of uses, from **earbuds** to **XR glasses** and **smartwatches**.
## Conclusion
The xMEMS Sycamore micro speaker is a significant advancement in audio technology. Its **solid-state design**, **ultra-compact dimensions**, and **superior sound performance** distinguish it as a premier product in the expanding market for **open-ear audio devices**.
