Microphone Turnkey Solutions

From 3D design reviews to fully tailored solutions, SELTECH is here to support you and allow you to always be innovative and competitive in the audio and electronics market.

Optimized Microphone integration with custom
Gasket & Mesh
Solutions

Our acoustic gaskets are designed to ensure optimal sealing and acoustic performance. They provide a perfect fit on the microphone and housing, effectively compensating for mechanical tolerances while preventing leaks that could cause echo or noise issues. Whether you need a standard or custom design, our gaskets offer tailored solutions for precise sealing. Additionally, they can be integrated with a protective mesh, providing dust and water resistance with protection levels ranging from IP54 to IP68, ensuring enhanced durability and reliability in various environments.

Microphone Solutions for
Seamless Integration

Our microphone on PCB/FPC solutions offer a versatile and efficient approach to acoustic integration. Designed for flexible connections to the mainboard, they provide a customizable all-in-one assembly, making them ideal for microphone arrays used in beamforming and noise cancellation applications. These solutions simplify production, as microphone handling and soldering of sensitive components are already managed, eliminating the need for component sourcing—a true plug-and-play solution. Additionally, they ensure high reliability, with rigorous quality control, guaranteeing repeatability, stability, and acoustic homogeneity across all end products.

Beamforming
Optimization &
Microphone Array
Design

Seltech provides expert support in the design and optimization of microphone arrays to achieve enhanced acoustic performance. Our team assists in the selection of MEMS microphones, ensuring the best fit for your application. We help define key parameters such as the number of MEMS microphones, distance, and positioning, optimizing array performance for beamforming and noise cancellation. Additionally, we offer acoustic sealing solutions, integrating custom rubber, waterproof mesh, and dustproof mesh to enhance durability and reliability.

Multi-Component Integration for a
Complete Solution

We enable the seamless integration of multiple components within an acoustic sub-assembly, allowing the addition of sensors, EEPROM, connectors, DSPs, and more. Our solutions can also be combined with Seltech’s other components, such as speakers or inductive/capacitive sensors, to create a fully plug-and-play acoustic system, streamlining development and production processes.

Thanks to our privileged partnership with Onsemi, Seltech is also capable of developing and providing Fully-Ready-Components (FRC) for Hearing Aids, integrating Onsemi chipsets such as the B100 or B300, along with MEMS microphones optimized through careful selection and PCB routing. These solutions are designed to ensure seamless connectivity with a balanced armature receiver, delivering an efficient and high-performance system for hearing aid applications.

Semi-Finished Microphone Solutions with
Custom Aesthetic Features

Seltech specializes in semi-finished solutions that integrate microphones with custom cosmetic and aesthetic components. We offer a wide range of design options, including laser marking, metal grids, fabric/textile covers, and even painted materials, ensuring both functionality and visual appeal. These solutions provide an optimized balance between acoustic performance and design, making them ideal for products where both sound quality and aesthetics are critical.

Certified Solutions for
Automotive & Medical Markets

Seltech operates in demanding industries such as automotive and medical, providing high-quality acoustic solutions that meet strict regulatory and performance requirements. We hold key industry certifications, including IATF 16949 for automotive, ISO 9001 for quality management, and ISO 13485 for medical devices, ensuring rigorous documentation management and compliance. Our expertise allows us to develop reliable, certified solutions tailored to the unique needs of these markets, guaranteeing performance, traceability, and quality consistency from design to mass production.
