What SELTECH does
SELTECH is a France-headquartered B2B manufacturer and solution provider specializing in acoustic components, capacitive sensors, digital signal processors, and wireless modules for OEMs across automotive, consumer electronics, healthcare (notably hearing aids), and industrial/IoT verticals. Founded in 1990 and headquartered in Créteil, the company distributes a broad portfolio of speakers (dynamic, BMR), receivers (dynamic, balanced armature), microphones (MEMS, ECM, boom, specialty, IA), buzzers, audio exciters, accelerometers, voice vibration sensors, ProxSense/ProxFusion capacitive sensors, Syntiant Neural Decision Processors, onsemi Ezairo hearing-aid DSPs, and Bluetooth modules, alongside custom speaker, microphone, and RIC module assemblies.
Its business model is sales-led and engineering-supported: SELTECH earns revenue primarily through hardware component sales augmented by professional acoustic design services that take customers from simulation and prototyping through validated production. Pricing is quote-based with multi-year contracts, and customer engagement is direct-to-engineer via the website (sample requests, SPL calculators, technical blog), field sales across France, the USA, and China, and presence at industry events including CES, Sensors Converge, Embedded World, Electronica, and EUHA. Acoustic laboratories in Paris (large anechoic chambers, ear simulators, broadband sources) and Nanjing (component and system-level characterization) anchor its turnkey acoustic engineering offering and underpin partner relationships with Knowles, Syntiant, Azoteq, onsemi, Tectonic Audio Labs, and Absolute Audio Labs.

- Cirrus Logic: Cirrus Logic designs low-power audio DSPs, codecs, and amplifiers for smartphones, headphones, and hearables. Overlaps with SELTECH's processor/wireless systems category and serves overlapping TWS and smartphone OEM customers.
- STMicroelectronics: STMicroelectronics manufactures MEMS microphones, sensors, and microcontrollers for consumer, automotive, and industrial applications. Competes with SELTECH's MEMS microphone and accelerometer lines, particularly in IoT and industrial segments.
- Foster Electric: Foster Electric is a Japanese manufacturer of speakers, microphones, and acoustic components serving automotive, consumer, and professional audio OEMs. Directly comparable component portfolio (dynamic speakers, microphones, receivers) to SELTECH's core acoustic components line.
- AAC Technologies: AAC Technologies is a major Chinese acoustic and haptic component manufacturer serving smartphone, automotive, and wearable OEMs with MEMS microphones, speakers, and piezo haptics. Competes broadly with SELTECH's component portfolio but at significantly greater scale.
- TDK (InvenSense): TDK's InvenSense division manufactures MEMS microphones, motion sensors, and acoustic components for consumer electronics and IoT. Overlaps directly with SELTECH's MEMS microphone and accelerometer product lines for OEM customers.
