The Customized audio solutions for children's AI voice-enabled devices Series
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.
- Our customized audio motherboards boast extensive applications, comprehensively covering all audio-enabled terminal products including the automotive equipment series, consumer electronics series, smart voice device series, AI voice device series, Bluetooth audio series, children’s audio product series, smart wearable product series, medical instrument equipment, pet device series, beauty equipment series, and household appliance series.
- Tailored to the unique demands of different industry scenarios, we have built a functional modular customization system — based on the design logic of standardized core modules and optional extended functions. While ensuring core performance such as audio transmission stability and acoustic fidelity, it precisely matches the structural dimensions, appearance, and functional requirements of devices across various industries (e.g., anti-interference requirements for automotive scenarios, low-power consumption standards for medical equipment, and safety and compliance requirements for children’s products).
- This approach not only flexibly controls the cost of motherboard customization (adding or removing audio modules such as Bluetooth, noise reduction, and AI voice interaction on demand to avoid waste from redundant functions) but also leverages a mature standardized customization process to help customers quickly complete product iteration and market launch.
- Whether for consumer-grade smart devices, industrial-grade communication terminals, or professional medical instruments, our customized audio motherboards deliver the triple value of scenario-specific adaptation, stable and reliable performance, and balanced cost-efficiency, serving as the core hardware backbone for audio motherboards in industries worldwide.

The Audio Mainboard & PCBA Motherboard Applications
Strengths of our company
Backed by over 25 years of proven expertise in the audio industry since 1998, we deliver precise tuning of frequency response curves, noise reduction algorithms, and sound profiles for key sectors including professional audio, smart homes, automotive applications, and consumer electronics. This addresses personalized needs such as high-fidelity playback and low-latency transmission. Through modular design to eliminate redundant functions, combined with in-house CNC equipment, sheet metal, and injection molding production lines, we achieve in-house supply of core components—reducing customization costs while accelerating time-to-market.
Our seasoned engineering team, with over 10 years of industry experience, provides end-to-end support covering chip selection, circuit design, firmware development, and mold customization. We enable hardware-software collaborative optimization to eliminate compatibility challenges. Complemented by a dedicated audio block design team and professional acoustic tuning specialists, our solutions support 8-channel high-definition audio output, ambient noise suppression, and other advanced features. Tailored to client requirements, our designs can meet Hi-Res Audio certification standards.
We leverage advanced manufacturing equipment including automatic diaphragm forming and semi-automatic welding systems, achieving motherboard precision of ±0.1mm. Coupled with an ISO-accredited quality management system and full-process inspections, we ensure consistency and reliability in mass production. Drawing on 8-layer 2-ounce copper circuit board technology—proven in high-end motherboards—we optimize power supply layouts and thermal dissipation structures. Paired with high-quality capacitors and isolated wiring, this enhances anti-interference capabilities and service life even in extreme environments.
We support seamless compatibility with wireless protocols such as Bluetooth, AI, and Wi-Fi, as well as multi-interface expansion including USB 3.2, HDMI, and DP. This facilitates seamless integration with a wide range of hardware devices, from smartphones and audio systems to medical instruments. Our dedicated after-sales team, with over 5 years of specialized experience, offers product maintenance, firmware updates, and technical consulting. We respond rapidly to clients’ personalized needs during installation and commissioning, ensuring long-term, stable partnerships.
