ZEH develops and manufactures tweeter speaker drivers for OEM and ODM audio projects. We match the tweeter size, structure, impedance, sensitivity, diaphragm, magnet and crossover requirements to your enclosure, amplifier and complete speaker system.
Our products are developed as configurable platforms rather than fixed retail models. Existing tweeter designs can be adapted around your installation space, acoustic target and production requirements.
A tweeter is a specialized speaker driver designed to reproduce the upper-frequency content of an audio system. It helps reproduce vocal detail, instrument overtones and other high-frequency information that a woofer or midbass driver cannot reproduce efficiently.
In most applications, a tweeter does not work alone. It operates together with a full-range, midrange, midbass or woofer driver, while a capacitor or crossover network controls which frequencies reach each unit.
The final result depends on more than the tweeter specification. Diaphragm material, sensitivity, crossover point, mounting angle, grille, enclosure and the response of the other speaker drivers all affect the sound of the completed system.
The tweeter drivers below represent existing diameter, frame, diaphragm, magnet, impedance and mounting platforms. They are starting points for OEM and ODM development rather than fixed retail products.
Each platform can be evaluated or modified according to your:
ZEH can supply the tweeter driver alone or integrate it with capacitors, grilles, mounting parts, wiring and connectors.
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.
A tweeter must work with the main speaker, crossover, amplifier and mounting position. ZEH supports OEM and ODM customers from early platform selection through prototype tuning and volume manufacturing.
We do not recommend a tweeter based only on diameter or rated power. Our engineers evaluate the main speaker, amplifier, crossover arrangement, mounting direction and target response before recommending a suitable platform.
This helps reduce common system problems such as:
ZEH can modify an existing tweeter platform according to your housing dimensions, installation method and electrical requirements.
Customization can include:
This allows customers to begin with a proven platform while adapting the product to their own equipment.
A tweeter that performs well during an individual test may behave differently after it is installed behind a grille or combined with another speaker driver.
ZEH can evaluate prototypes through:
Testing helps identify system-matching and structural problems before tooling or mass production.
With speaker manufacturing experience since 1998, ZEH supports projects from initial requirements and samples through pilot production and mass manufacturing.
Production is controlled according to the confirmed sample and agreed project specifications, including materials, assembly structure, electrical parameters and acoustic performance.
Our typical development process is:
Requirement Review → Platform Selection → Sample Development → System Matching → Prototype Validation → Pilot Production → Mass Production
A tweeter is a speaker driver designed mainly for high-frequency sound. It is normally used together with a woofer, midbass, midrange or full-range speaker to extend the upper-frequency response of the complete audio system.
A tweeter is generally not suitable as the only speaker because it is not designed to reproduce middle and low frequencies. Most systems use it as part of a two-way or three-way arrangement with another speaker driver.
For products that require one driver to reproduce speech, music and notification sounds, a full-range speaker is usually more appropriate.
A dome tweeter uses a dome-shaped diaphragm and is common in automotive, home and multimedia audio systems. A cone tweeter uses a small cone-shaped diaphragm and can provide a simple, cost-effective structure.
A horn-loaded tweeter couples the driver to a horn or waveguide to increase efficiency and control sound dispersion. The correct type depends on the product size, listening distance, sensitivity target and system design.
Tweeter size should be selected according to the available mounting area, depth, desired frequency response, sensitivity, power requirement and main speaker configuration.
The outside diameter alone is not enough. Dome diameter, magnetic circuit, mounting angle and grille structure must also be considered.
The impedance should match the amplifier and the rest of the speaker system. A 4-ohm tweeter may be suitable for many automotive and compact electronic systems, while an 8-ohm tweeter is often used in home, commercial and professional audio equipment.
The final choice must also consider crossover components and system sensitivity.
Most dynamic tweeters require a capacitor or crossover network to prevent unsuitable low-frequency energy from reaching the driver. The required crossover arrangement depends on the tweeter’s impedance, resonance, power handling and the response of the main speaker.
ZEH can supply the bare tweeter or integrate selected crossover components into the assembly.
Different diaphragm materials have different mass, stiffness, damping and environmental characteristics. These differences can influence frequency response, sound character, sensitivity and durability.
The material should be selected according to the target application and verified in the complete system rather than judged by material name alone.
Yes. Automotive tweeter projects can include customized diameter, mounting structure, grille, bracket, wiring, connector, impedance, magnet and crossover components.
To recommend a suitable platform, we need the installation dimensions, mounting location, amplifier information, main speaker specification and target sound requirements.
Please provide as much of the following information as possible:
A physical sample or existing speaker specification can also help accelerate the evaluation.
Yes. Development can begin with an existing tweeter platform or a modified sample. After the mechanical structure and electrical parameters are confirmed, the sample can be evaluated inside the customer’s product.
Further adjustments can then be made to the diaphragm, magnet, mounting structure, crossover or related module components before pilot production.
