ZEH develops and manufactures midrange speaker drivers for OEM and ODM audio projects. We match the driver size, impedance, power, sensitivity and acoustic response to your enclosure, amplifier, crossover and complete speaker system—not to a fixed retail specification.
A dedicated midrange speaker helps reproduce vocals, dialogue and other important middle-frequency content with greater control and clarity.
It is commonly used in multi-driver audio systems where a woofer or midbass driver handles lower frequencies and a tweeter handles higher frequencies. By assigning the middle-frequency range to a dedicated driver, the system can achieve clearer vocals, higher output and a more controlled transition between the low- and high-frequency sections.
The final performance does not come from the midrange driver alone. Cone material, suspension, voice coil, magnetic circuit, enclosure, grille, crossover and the adjoining speaker drivers all influence the usable result.
The speaker drivers below represent existing size, frame, magnet, impedance and power platforms.
They are starting points for OEM and ODM development rather than fixed retail products. Each platform can be evaluated or modified around your enclosure, amplifier, crossover, adjoining speaker drivers, sound target and production requirements.
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.
ZEH develops midrange speaker solutions around the actual structure, electronics and acoustic requirements of each audio system.
From platform selection and system matching to component integration and prototype validation, we help OEM and ODM customers reduce development risks and move projects toward production more efficiently.
ZEH evaluates the midrange driver together with the woofer, tweeter, crossover, amplifier, enclosure and mounting position.
This helps us recommend a platform that fits the actual product and supports the required vocal clarity, sound pressure and middle-frequency performance.
Our existing midrange platforms support faster development while allowing project-based adjustments to the size, frame, impedance, power, sensitivity, magnetic circuit and acoustic response.
When an existing platform cannot meet the installation or performance requirements, further structural modification or new tooling can be evaluated.
Beyond midrange speaker drivers, ZEH can coordinate enclosures, grilles, acoustic mesh, wire harnesses, connectors, crossover components and amplifier requirements.
This improves component compatibility and reduces the complexity of managing multiple suppliers.
ZEH supports sample development and prototype validation before production.
We evaluate installation compatibility, electrical parameters, crossover matching, acoustic performance and potential assembly issues, helping customers reduce development risks and improve production consistency.
