Balanced armature receivers are specialized miniature speakers commonly used in hearing aids and professional in-ear monitors.
Sonion manufactures receivers designed for different sound output requirements and applications. These components convert electrical signals into sound, helping users experience clear and detailed audio.
They are available in different configurations, including single, dual, hybrid, and electrostatic solutions for specialized applications.
3. Receiver-in-Canal (RIC) Solutions
Receiver-in-Canal technology is widely used in modern hearing aids. These devices place the receiver inside the ear canal while keeping other electronic components in a separate housing.
Sonion develops customized RIC solutions and ready-made systems that hearing aid manufacturers can incorporate into their designs.
These technologies support flexible product development and help manufacturers create hearing instruments with different performance levels and design requirements.
4. Connector Systems
Reliable connections are essential for the proper operation of electronic hearing devices.
Sonion produces connector systems, including plugs, sockets, and cables designed to provide flexibility and dependable electrical connections.
These components help manufacturers integrate different parts of hearing instruments while maintaining functionality and reliability.
5. Sensors and Micromechanical Components
Sonion also develops specialized sensors and micromechanical components for modern audio applications.
Its technologies include voice-pickup bone sensors that can support clearer communication in challenging environments. The company also offers biometric sensor solutions for certain hearing aid applications.
Other components, such as telecoils, trimmers, dampers, push buttons, and volume controls, help improve the functionality and usability of hearing instruments.
Sonion’s Contribution to Hearing Healthcare
Hearing loss affects millions of people around the world. It can make communication difficult, reduce social participation, and affect everyday activities.
Modern hearing aids provide important support for people experiencing hearing difficulties. However, their performance depends on the quality of the miniature components inside them.
Sonion contributes to hearing healthcare by developing advanced microphones, receivers, sensors, and other technologies used by hearing aid manufacturers.
