As a renowned loudspeaker design firm, ZEH Audio specializes in Speaker driver manufacturing. With exceptional quality, it stands as a trusted partner for speaker makers, boasting core advantages as follows:
When selecting a speaker, the outer diameter should not be the only consideration. Available installation space, enclosure volume, amplifier output, impedance, rated power, sensitivity, frequency response, target sound pressure level, and operating environment should all be evaluated.
Even speakers of the same size can deliver noticeably different sound performance due to differences in diaphragm material, voice coil, NdFeB magnet, acoustic enclosure, and sound outlet design.
Small-size speakers are designed for electronic devices with limited installation space. They enable voice prompts, alarm tones, hands-free communication, and music playback within compact product structures.
However, a smaller speaker does not mean acoustic design can be overlooked. Actual volume, sound quality, and low-frequency performance are also influenced by amplifier output, enclosure volume, sealing, sound outlet area, and mounting position. For products requiring stronger bass or higher sound pressure levels, performance should be optimized through the coordinated design of the speaker, amplifier, acoustic enclosure, and overall product structure.
Each type of loudspeaker below can be selected from our existing size platforms or customized to suit your product structure, acoustic enclosure, amplifier specifications, target sound performance, and mass-production requirements. Customizable parameters include speaker size, shape, depth, mounting holes, impedance, rated power, magnet, diaphragm, mounting method, and wire connection. Speaker grilles can also be added upon request.
Based on your product structure and target sound performance, ZEH can recommend or customize small-, medium-, and large-size speakers for your project. We also provide acoustic enclosure design, amplifier matching, PCBA development and debugging, DSP tuning, plastic enclosure manufacturing, sample validation, and mass-production services—helping ensure stable acoustic and mechanical integration between the speaker and the finished product.
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.
Small speakers operate within tighter mechanical, acoustic and power constraints than larger drivers. ZEH Audio combines speaker engineering, system integration and scalable manufacturing to help OEM/ODM customers develop compact audio solutions that fit the product, meet the target sound performance and remain consistent in mass production.
Small speaker performance depends on more than driver diameter. Our engineers evaluate mounting depth, frame shape, magnet size, sound outlet position, enclosure volume and available internal space together to develop a speaker that fits your product without compromising the required acoustic performance.
We evaluate the speaker together with the enclosure, amplifier, PCBA, acoustic chamber, sound outlet, sealing structure and wiring. This system-level approach helps achieve clearer voice reproduction, sufficient SPL and more stable sound performance within limited product space and power budgets.
Speaker samples can be evaluated for frequency response, sensitivity, impedance, distortion, mechanical fit and other project-specific requirements before mass production. Controlled materials, production processes and acoustic testing help maintain consistent performance from approved samples to production batches.
With more than 20 years of loudspeaker manufacturing and engineering experience, ZEH can start from an existing speaker platform or develop a customized solution around your product requirements. We support projects from speaker selection and structural modification through sample validation, enclosure integration and volume production.
When selecting speakers for children’s toys, prioritizing compliance with international certification and testing standards is essential to ensure safety in use. In terms of sound quality, it needs to align with specific requirements—some clients prefer rich mid-low frequencies, while others focus on clear mid-high frequencies. We will combine the parameters of your PCBA motherboard and the enclosure structure to match the speaker and fine-tune the sound effect in a targeted manner, creating the expected pure sound performance.
No need to worry! ZEH has a professional acoustic team and an enclosure structure design team. We can conduct in-depth alignment with your PCBA motherboard specifications, adjust speaker parameters and optimize the enclosure structure from the perspective of acoustic adaptation. This ensures the enclosure and speaker perfectly match, achieving ideal sound output.
Yes. ZEH has a comprehensive production layout, covering professional operation areas such as a speaker workshop, plastic mold workshop, metal mold workshop, and wire/harness workshop. We can provide full-chain supporting services from enclosure design and production, speaker manufacturing to finished product assembly, meeting your integrated production needs.
