ZEH audio is a leader in innovative, high-performance single and multi-channel audio amplifiers for applications.
With over 20 years of digital audio experience, you can count on ZHE audio for amplifiers with the latest digital technology and advanced feature sets. ZEH Digital Amplifiers are compact class-D designs engineered for a wide variety of speaker configurations. Features vary by model and may include: Digital (S/PDIF) and analog inputs, enabling direct connection from digital and analog low and high level (speaker) outputs. Some models offer Digital Signal Processing (DSP) to provide numerous user-controlled features including crossovers, filters, frequency equalization and dynamic range control.
ZEH’S amplifiers are reliable, feature rich, and cost effective. ZEH amps are available in a variety of stock configurations, with power supply and upgrade options, or we can design a custom solution that exactly fits your audio 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.
