A modern MRI scanner in a clean, high-tech medical imaging room illuminated by cool blue lighting. The cylindrical scanner features a glowing circular opening and an extended patient table positioned to slide into the machine. The surrounding room has smooth reflective floors, sterile walls, and built-in control panels, creating a futuristic and clinical atmosphere. The image conveys precision, advanced medical technology, and the calm, controlled environment of a professional diagnostic facility.

MEMS Speakers for Magnetic Resonance Imaging (MRI) Headphones

Thanks to the absence of ferromagnetic materials, USound speakers can be used in a number of applications, such as electromagnetic interference (EMI)-sensitive products and medical audio devices. Magnetic Resonance Imaging (MRI) headphones are a great example of such medical products that require magnetless components.

MRI is a type of medical imaging technique that provides three-dimensional anatomical images of the human body. It is commonly used to diagnose and prevent a wide variety of medical conditions, such as brain tumors, aneurysms, and dementia. MRI machines produce loud noises during the procedure, making the use of a protective headset necessary for the patients’ safety. The MRI headphones can also be used to communicate with the patients inside the machine and to produce soothing sounds that reduce their feelings of anxiety. It is important to note that common headphones that are available on the market are not MRI-compatible. These medical audio devices cannot contain ferromagnetic parts or components, making many conventional speakers unsuitable for MRI applications.

MEMS Speaker Applications

Thanks to their compact form, integration flexibility, absence of ferromagnetic materials, robustness, and sound precision, USound’s microspeakers can be used in a number of applications:

True Wireless Systems (TWS) earphones

Augmented Reality & Virtual Reality Glasses and Headsets

Audio glasses

Ultrasound

Magnetic Resonance Imaging (MRI) Headphones and Medical Devices

Over-the-counter (OTC) hearing aids

A close-up photograph showing a pair of precision tweezers holding a tiny USound MEMS speaker from the Ganymede series, designed for MRI-compatible headphones. The miniature speaker component has a sleek, rectangular metallic body with a reflective surface, emphasizing its micro-scale engineering. The background is dark and softly blurred, highlighting the fine details of the component and the tweezers’ metallic texture. Below, a faint grid-like pattern suggests a high-tech or laboratory environment. The image conveys innovation, precision, and advanced acoustic microtechnology suitable for use in medical and MRI-safe audio applications.

MRI Headphones Components

MRI headphones require various components, including magnetless speakers, plastic headbands, foam padding, and much more. USound’s MEMS speakers of the Ganymede series are the ideal MRI speaker component.

Not only are the magnetless speakers safe-to-use in MRI machines, but their compact size frees-up space for other essential components. As a result, MEMS-based MRI headphones can offer additional benefits that exceed ear protection. Advanced MRI-compatible headphones can also be used as communication and media player devices, producing soothing sounds that relieve patients’ anxiety.

USound MEMS Speaker Benefits for MRI Applications

The benefits of USound speakers for MRI audio devices include but are not limited to:

  • No magnetic field and absence ferromagnetic materials for safe intergration into MRI and EMI-sensitive applications.
  • Excellent audio performance and clarity for the most high-performing MRI headphones.
  • Automated manufacturing process.
  • Low heat generation for safe-to-use protective headsets.
  • Compact size for unlimited design flexibility.
  • Ultra low vibrations and lightweight components for increased comfort.
  • Drop-proof design with 100% survival rate at a 1.9m drop test.
