Customize One-Stop Electronic Board & OEM/ODM Series
Our customized mainboards 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.

FAQs
Customizing motherboards for kids’ devices centers on safety prioritization and child-centric scenario adaptability, adopting a standardized, targeted customization workflow to strike a seamless balance between functionality and protective capabilities. The detailed steps are as follows:
1. Define Core Product Requirements
First, map out the device’s intended use cases (e.g., early education devices, kids’ smartwatches, educational toys), functional modules (positioning, voice interaction, sensors), and safety benchmarks. Outline kid-specific safety requirements—including low radiation, interfaces compatible with food-grade materials, and short-circuit prevention—while validating compliance with relevant children’s safety certifications (e.g., China Compulsory Certificate (CCC) for children’s products).
2. Solution Customization & Prototype Development
Based on the defined requirements, engineers incorporate low-power chips into the motherboard architecture to extend battery life, integrate anti-misoperation circuit safeguards, and minimize the motherboard footprint to align with the compact form factors of kids’ devices. Following the finalization of the initial solution, a prototype motherboard is rapidly fabricated to validate functional compatibility, safety, and stability.
3. Testing & Mass Production Launch
Comprehensive multi-dimensional testing is imperative, covering safety voltage withstand tests, drop and shock resistance evaluations, and functional compatibility assessments to ensure full adherence to children’s product safety standards. Once all tests are passed, mass production can kick off. Additionally, dedicated after-sales technical support is provided to guarantee the long-term reliable operation of the motherboards.
The entire process is anchored in the unique needs of children’s usage scenarios, not only meeting the device’s functional demands but also fortifying a robust safety barrier.
