ZEH AUDIO develops custom speaker drivers, acoustic enclosures and plastic housings for global OEM and ODM projects. Instead of adapting your product around a standard speaker, we engineer the complete audio solution around your available space, amplifier output, target sound, appearance and operating environment.
Choose from a wide range of sizes, shapes, power ratings, impedances, colors, materials and mounting configurations—with engineering support from concept development and rapid prototyping to acoustic validation and mass production.
All of speakers below allow flexible size selection and customization according to your product structure, acoustic cavity design, power amplifier specifications, target sound quality and mass-production requirements. Adjustable parameters include speaker size, shape, height, mounting holes, impedance, rated power, appearance, color, mounting method and wire connections. Speaker grilles can also be added to meet project-specific needs.
The ZEH engineering team provides full-range technical support, including speaker selection, acoustic cavity matching, sample development, acoustic tuning and reliability validation. Our support helps customers shorten product development cycles and ensures full-range speakers achieve stable and consistent acoustic performance, excellent assembly compatibility, and consistent performance across production batches within end-products.
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 devices have different requirements for sound, space, and assembly. ZEH develops speakers, acoustic chambers, enclosures, and audio electronics together to optimize sound performance for the intended application, with support from prototype validation through volume production.
Many OEM/ODM customers find that their selected speakers deliver disappointing sound once installed in the finished product. Performance largely depends on how well the drivers, acoustic chambers, enclosures, and amplifiers work together. Based on your product’s mechanical design, available installation space, and target sound, ZEH provides one-stop services covering custom speakers, acoustic chamber and enclosure development, amplifier and audio PCBA matching, wiring harnesses, acoustic tuning and testing, and volume assembly to help achieve sound performance that meets your complete product requirements.
We evaluate speaker drivers, acoustic chambers, enclosures, audio PCBAs, DSP, and wiring harnesses together, taking into account installation space, target sound quality, amplifier specifications, and operating conditions to align component design requirements.
We assess speaker selection alongside acoustic chamber volume, sound openings, mounting locations, and sealing structures to balance speech clarity, volume, bass performance, and distortion control within limited space.
We offer customization of dimensions, shape, mounting depth, hole locations, impedance, power rating, wiring, and connectors, along with matching grilles, seals, and enclosures. This helps reduce mechanical interference and repeated adjustments during product assembly.
We provide plastic enclosure design, mold development, injection molding, and CNC-machined metal components, balancing acoustic functionality, structural strength, surface finish, and brand aesthetics. Based on the operating environment, target cost, and production requirements, we also evaluate diaphragm, surround, magnet, and enclosure materials to balance real-world performance with manufacturing feasibility.
1. Space Adaptation: Customized speakers seamlessly integrate into the customer’s enclosure structure, without wasting any space. Regular speakers have fixed diameters, thicknesses, and mounting specifications. When faced with the internal spaces of different products (such as ultra-thin Bluetooth speakers, micro-sensors, and irregularly shaped home appliances), they often encounter issues like “being too large to fit” or “being too small leaving gaps”.
2. Acoustic Performance: Customized speakers can be optimized based on customer needs. For example, customized plastic or metal enclosures, along with PCBA mounting hole adjustments and PCBA power amplifier tuning, align the sound quality more closely with the product’s overall audio performance. They not only allow adjustment of the frequency response range (e.g., enhancing mid-to-high frequencies for voice interaction devices to make human voices clearer, or optimizing low frequencies for portable speakers to boost bass texture) but also work with the product enclosure (or custom-built exclusive speaker cavities). By adjusting cavity volume and sound outlet size, acoustic reflection interference is reduced, avoiding issues like “blurred sound quality and resonant noise” common in regular speakers. Additionally, performance can be tuned to usage scenarios—such as enhancing volume and resistance to environmental noise for outdoor devices, or improving sound delicacy for indoor devices.
3. Scenario and Functionality: They precisely meet the customer’s specific needs. For instance: 1.Protection Adaptation: Customizing waterproof (IP67/IP68), dustproof, and high-temperature resistant speaker structures for outdoor, automotive, and bathroom products.2.Installation Adaptation: Creating “ear-contact mounting structures” for wearable devices, and custom mounting angles for car doors/instrument panels for automotive products.3.Special Functions: Developing low-electromagnetic radiation speakers for medical devices, and safety designs with “anti-distortion and low maximum volume limits” for children’s products.
4. Aesthetic and Structural Design Integration: They blend into the product without compromising design integrity. Customized speakers and enclosures can use materials and colors consistent with the product, even hiding sound outlets in product gaps to preserve aesthetic completeness. Materials can be selected per customer requirements, such as plastic, metal, or aluminum enclosures. Some specially customized speakers and their enclosures can even serve as part of the product’s structural support (e.g., replacing some internal brackets), reducing the number of product components and simplifying the assembly process.
