The Customized Beauty Instruments and Equipment Solutions for Clients
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 PCBA & PCBA Motherboard Applications
Specialized for beauty and salon applications, our beauty equipment audio motherboards are designed for devices including smart hair styler voice guidance modules, nail tool audio promptors, beauty instrument operation voice broadcasters, and salon-specific audio devices. This series addresses core demands for low-noise operation, clear and gentle voice output, compact size adaptation, and compatibility with beauty equipment power supplies.
This series comprises AI smart assistants, voice-controlled switches, smart access control voice modules, and far-field voice interaction terminals. Core requirements here include high-precision far-field voice recognition, resistance to ambient noise, low-latency response, and semantic interaction compatibility.Core Motherboard Configurations & Advantages:Integrated with proprietary patented noise reduction algorithms for multiple scenarios, the motherboards support far-field voice wake-up within a 5-20 meter range with a recognition accuracy rate of ≥95%, adapting to complex environments. They are equipped with low-power AI voice processing chips and support docking with mainstream voice assistant protocols for rapid function integration. The modular design allows for the addition or removal of multiple voice recognition and multi-round dialogue functions as needed, catering to different smart scenarios.
Need to highlight “creativity + memorability”, align with festival/brand IP themes, and meet the needs of “scenario-based interaction” (e.g., synchronized audio playback with books), all customized according to customer requirements.
Adapted to the limited space in vehicles, able to withstand high and low temperatures/vibration environments. They also align with the brand visual identity of automobile manufacturers (e.g., casing texture) and meet in-vehicle audio interaction needs (e.g., clear voice announcements), all customized according to customer requirements.
Strengths of our company
