ZEH develops and manufactures full-range speaker drivers for OEM and ODM projects. We match the speaker size, structure, impedance, power, materials and acoustic response to your enclosure, electronics and end-use environment—not to a fixed off-the-shelf specification.
One driver can simplify the acoustic system, reduce assembly complexity and make better use of limited internal space—provided the driver, enclosure and amplifier are developed as one system.
A full-range speaker is designed to reproduce a broad usable frequency range from one driver. It is often selected when a device needs speech, music and notification sounds but has limited space, cost or assembly room for a multi-driver system.
The real performance does not come from the driver specification alone. Diaphragm design, suspension, voice coil, magnetic circuit, enclosure volume, sound outlet and amplifier 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 modified around your enclosure, amplifier, 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 full-range speaker solutions around the actual structure, electronics and acoustic requirements of each device. From platform selection and flexible customization 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 speaker together with the enclosure, installation space, amplifier and sound outlet. This helps us develop a full-range speaker that fits the actual device and meets its speech, alert tone or general audio requirements.
Our existing speaker platforms support faster development while allowing customization of size, frame shape, impedance, power, sensitivity and materials. When necessary, we can also evaluate structural modifications or new tooling.
Beyond speaker drivers, ZEH can coordinate enclosures, grilles, acoustic mesh, wire harnesses, connectors and amplifier requirements. This improves component compatibility and reduces the complexity of managing multiple suppliers.
ZEH supports sample development and validation before production. We check installation compatibility, electrical parameters, acoustic performance and potential assembly issues, helping customers reduce development risks and improve production consistency.
A full-range speaker is suitable when your device needs speech, alerts and general audio from one compact driver. ZEHSMAUDIO can evaluate your enclosure, amplifier and sound requirements before recommending a solution.
Yes. We can customize the diameter, height, mounting depth, hole position and frame shape to fit your product structure.
Yes. You can provide a 2D drawing, 3D file, enclosure sample or complete device. Our engineers will review the available space, mounting structure and sound outlet.
Yes. Impedance, rated power, sensitivity, resonant frequency and frequency response can be adjusted according to your amplifier and acoustic target.
Yes. Please provide the amplifier output, operating voltage, load impedance and PCB information. We can help reduce the risk of low volume, distortion or power mismatch.
A small speaker can provide clear speech and useful low-frequency output, but deep bass is limited by speaker size and enclosure volume. We can optimize the diaphragm, magnetic circuit and enclosure matching for better performance.
Available options include paper, PP, PET and composite diaphragms, as well as rubber, foam or cloth surrounds. Ferrite and neodymium magnets are also available.
Yes. ZEHSMAUDIO supports engineering samples, acoustic testing and pilot production before mass production.
MOQ and lead time depend on the speaker size, tooling requirements and customization level. We will confirm them after reviewing your project information.
ZEHSMAUDIO has supported OEM and ODM audio projects since 1998. We can coordinate speakers, enclosures, audio PCBA, wire harnesses and related components from sampling to mass production.
