Beyond the speaker domain, ZEH AUDIO also covers two core product categories: Microphones and Motors. It not only provides a rich selection of standardized products but also offers customized services for the motor category, fully meeting your diverse needs.
ZEH Audio is a professional manufacturer specializing in audio acoustics and vibration components. Beyond the R&D and manufacturing of various high-end speakers, it also focuses on the specialized R&D, production, and manufacturing of various microphones, motors, and vibration motors. Its entire range of products features integrated customization of plastic and metal molds.
In audio devices, the technical performance of motors and microphones directly determines the upper limit of product experience: Motors must have a vibration precision of ±0.1mm and a rapid response capability of 5ms to achieve delicate layering of headphone vibration feedback, avoiding distortion or delay. Microphones, on the other hand, need to reach a signal-to-noise ratio (SNR) of -38dB to -60dB and a full-frequency sound pickup range of 20Hz to 20kHz, ensuring that when external sounds are converted into electrical signals, original sound details are retained without background noise.
As an audio technology expert, ZEH, with over 20 years of experience in R&D of core components, can not only realize customized parameter tuning for speakers, motors, and microphones but also cover the full-process technical implementation of audio accessories across multiple industries—from material selection and circuit design to finished product reliability testing (such as high-low temperature resistance and anti-drop tests)—providing customers with technical solutions that meet the highest industry standards.
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.
In audio devices, motors and microphones are two key components: the core function of a motor is to provide vibration feedback, which is commonly used in scenarios such as vibration in headphones to enhance the user’s sensory experience beyond hearing; a microphone, as the core component for sound collection, can accurately convert external sound into electrical signals, laying the foundation for audio input.
As an audio technology expert, ZEH, backed by profound technical accumulation, can fully cover the R&D and customization needs of audio accessories across multiple industries. We provide customers with professional support from core components to overall solutions, helping your products achieve better audio performance.
