As a high-end custom audio expert, ZEH specializes in custom audio products, one-stop PCBA R&D/ speaker systems. Crafted with premium acoustic components, high-temperature-resistant PCBs, and high-performance main control chips, our solutions serve automotive devices, consumer electronics, AI voice smart audio, professional instruments, and intercom terminals—with deep customization for your unique appearance and functional needs.
ZEHSMAUDIO can adapt an existing speaker platform or develop a modified structure based on your installation space, sound target, electronics, enclosure and production requirements.
We review your housing dimensions and mounting structure before selecting the frame and magnetic circuit.
Round, oval, rectangular and low-profile frames can be adapted to internal ribs, PCB positions and assembly methods.
Speaker parameters are evaluated together with the amplifier, enclosure, listening distance and required sound performance.
Diaphragm, surround and magnet materials are selected according to the target sound, environment and cost requirements.
The project can include the enclosure, grille, wiring, connector, sealing components and amplifier matching.
Different products place different demands on speaker size, vocal clarity, sound pressure, enclosure volume, power consumption and long-term reliability. Select an application to see how the acoustic priorities change.
For smart terminals and voice-enabled products, the speaker must reproduce speech clearly inside a compact enclosure while working together with the microphone, audio PCBA and product housing.
Low-profile structure, vocal-band tuning, cavity matching and complete audio hardware coordination.
Interactive toys and learning products need clear speech, comfortable loudness and a structure that remains consistent across repeated use and mass production.
Shape customization, controlled sound pressure and voice-frequency optimization for educational content.
Voice prompts and alarms must remain understandable and stable, while the speaker or module also fits the assembly, supply and reliability requirements of the medical device.
Integrated modules, stable acoustic output, controlled materials and documented validation before production.
Doorbells, panels, sensors and connected terminals often require a small speaker that delivers clear prompts or alerts without taking valuable space from the rest of the electronics.
Compact structures, alert-tone tuning, optional environmental protection and connector integration.
Trackers, training products and portable electronics need compact sound components that survive movement, limited battery capacity and repeated everyday handling.
Small-footprint drivers, efficient notification output and optional sealing or integrated module assembly.
ZEH’s PCBA Audio Mainboard delivers ultra-low noise, distortion-free sound with professional acoustic tuning. We offer custom R&D, high integration, and stable mass production, backed by strict quality control and fast delivery. Compact, power-efficient, and highly compatible, it perfectly elevates your electronic device design.
