Multimedia audio speakers are electroacoustic components designed to reproduce speech, music, video soundtracks, gaming audio, and system notification sounds. They convert electrical signals from an amplifier into audible sound and are widely used in consumer electronics, AI-enabled devices, children’s products, smart home systems, audio equipment, automotive electronics, medical devices, robotics, and various smart terminals.
Compared with conventional speakers primarily used for notification tones or alarms, multimedia audio speakers place greater emphasis on a wider frequency response, sound clarity, output volume, balanced low-, mid-, and high-frequency performance, as well as durability and stable operation during extended playback. Power handling and impedance can be customized according to the speaker size and application requirements, covering both low-power and high-power configurations. Depending on the product structure, available installation space, amplifier specifications, and target sound quality, the audio system may use a full-range speaker, a woofer-and-tweeter combination, a dual-speaker stereo configuration, or a multi-driver design.

Clear, Natural Voice Reproduction: Optimized low-, mid-, and high-frequency response improves the clarity of dialogue, voice prompts, and video content.
Richer Music and Bass Performance: The diaphragm, voice coil, magnet, acoustic enclosure, and bass-enhancement structure can be optimized to deliver fuller, more powerful sound.
Compact and Easy to Integrate: Speaker size, shape, height, mounting holes, and connection methods can be customized to fit the available internal space, making them ideal for demanding, space-constrained products.
Stereo and Multi-Driver Configurations:Available configurations include left and right channels, full-range speakers with tweeters, or full-range speakers with woofers to improve soundstage, audio detail, and coverage.
Flexible Power and Impedance Options: Impedance, rated power, sensitivity, and frequency response can be configured according to the amplifier output and the device’s power system.
Multimedia speakers typically consist of a neodymium or ferrite magnet, copper or aluminum voice coil, diaphragm, surround, spider, aluminum or steel frame, top and back plates, washer, terminals, and other components. Through careful design and matching of the magnetic circuit, voice coil, diaphragm materials, and structural parameters, the speaker can achieve improved sensitivity, frequency response, sound detail, bass performance, and long-term reliability.
All of the multi-function audio 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.

Medium-size speakers require a careful balance between output capability, frequency response, installation space and system efficiency. ZEH Audio combines speaker engineering, acoustic integration and scalable manufacturing to help OEM/ODM customers develop drivers that match the mechanical and acoustic requirements of their finished products.
Medium speakers are often expected to deliver stronger output and broader usable frequency response than compact drivers while still fitting within controlled installation space. Our engineers optimize the diaphragm, suspension, magnetic circuit and voice coil to achieve the required balance of sensitivity, power handling, frequency response and distortion.
Different products require different acoustic priorities. ZEH can configure speaker diameter, impedance, rated power, frequency response, sensitivity, frame structure and material selection according to applications such as multimedia systems, professional audio equipment, automotive electronics, smart devices and commercial sound products.
Speaker performance depends heavily on the surrounding system. We evaluate the driver together with enclosure volume, cabinet structure, acoustic chamber, crossover, amplifier, PCBA and sound outlet design to help achieve more stable frequency response, sufficient SPL and better overall system performance.
Before mass production, prototypes can be evaluated for frequency response, sensitivity, impedance, distortion, power handling, mechanical fit and other project-specific requirements. With controlled materials, production processes and acoustic testing, ZEH helps maintain consistent performance from approved samples to production batches.
A medium-size speaker driver is a compact-to-mid-sized loudspeaker unit commonly used where a product requires stronger output and fuller sound than a miniature speaker but does not have enough space for a large speaker driver.
At ZEH Audio, medium-size speakers generally cover approximately 1.5 to 4 inches and can be configured for voice reproduction, music playback, notification sounds, multimedia audio, and other embedded audio applications.
A medium speaker is classified primarily by its physical size, while a midrange speaker is classified by the frequency range it is designed to reproduce.
A 2-inch, 3-inch, or 4-inch speaker can therefore be a full-range speaker, midrange driver, midbass driver, or another acoustic configuration depending on its diaphragm, magnetic circuit, suspension, voice coil, enclosure, and target frequency response.
If your project requires a specific frequency band rather than simply a certain speaker size, the required frequency response should be confirmed during speaker selection.
ZEH Audio offers medium-size speaker drivers in a range of diameters and frame structures, including approximately 1.5-inch, 2-inch, 2.5-inch, 3-inch, 3.5-inch, and 4-inch options.
The final dimensions do not have to follow a standard round diameter. Frame shape, mounting holes, overall height, mounting depth, and other mechanical dimensions can also be adapted according to the available space inside your product.
The correct speaker diameter depends on more than the available mounting space.
A larger diaphragm can generally support higher acoustic output and improved low-frequency performance, but it also requires more installation space and usually a larger acoustic enclosure. A smaller driver may be easier to integrate but may require different tuning to achieve the required SPL and frequency response.
We recommend evaluating speaker diameter together with enclosure volume, mounting depth, amplifier power, target frequency response, listening distance, and required sound pressure level.
Yes. 4Ω and 8Ω are common impedance options for medium-size speaker drivers.
The correct impedance should be selected according to the amplifier circuit, supply voltage, required power output, and system configuration. For stereo or multi-speaker systems, the overall electrical load should also be considered before selecting the speaker impedance.
The required rated power depends on the amplifier output, speaker size, target SPL, enclosure design, and intended operating conditions.
Medium-size speakers can cover a relatively broad range of power requirements, so selecting a driver only according to wattage is not recommended. The speaker should be matched with the actual amplifier and acoustic system to avoid insufficient output, excessive distortion, overheating, or unnecessary over-specification.
Yes. Many medium-size speakers can be designed as full-range drivers for products that need voice, music, system sounds, and general multimedia playback from a single speaker unit.
However, whether a single driver can meet the required sound quality depends on the target frequency response, enclosure volume, maximum output level, and product application.
For systems requiring stronger bass or more detailed high-frequency reproduction, a medium full-range speaker may also be combined with a woofer, passive radiator, or tweeter.
Medium speaker drivers are suitable for many products that require a balance between installation space and acoustic output.
Typical applications include desktop multimedia systems, Bluetooth speakers, smart home products, vending machines, kiosks, self-service terminals, medical equipment, industrial control equipment, gaming devices, educational electronics, AI voice devices, and other embedded audio systems.
The appropriate speaker configuration depends on whether the product prioritizes speech intelligibility, music quality, alarm output, sound coverage, or a combination of these requirements.
Both neodymium and ferrite magnets can be used depending on the required speaker structure and project priorities.
Neodymium magnets are often selected when compact size, reduced weight, or a strong magnetic circuit within limited installation space is important. Ferrite magnets can be suitable for applications where a larger motor structure is acceptable and cost is an important consideration.
The magnet type should be selected together with the voice coil, diaphragm, sensitivity target, speaker dimensions, and required power handling.
The enclosure has a major influence on the final acoustic performance of a medium-size speaker.
Internal volume, acoustic sealing, front and rear cavities, vent design, mounting position, grille opening, and enclosure materials can all affect frequency response, bass performance, distortion, and output level.
For this reason, testing a speaker in free air alone may not accurately represent how it will perform inside the finished product. Providing your enclosure drawing or prototype allows the speaker and acoustic structure to be evaluated together.
Yes. ZEH Audio can evaluate custom frame dimensions, mounting depth, mounting holes, terminals, wire positions, connectors, grilles, sealing structures, and other mechanical features.
For products with restricted internal space, we recommend providing a 2D or 3D enclosure drawing so that both the speaker dimensions and assembly clearances can be reviewed before tooling or sample development.
Yes. Frequency response, sensitivity, resonant frequency, impedance, rated power, and other acoustic parameters can be adjusted according to the requirements of the finished product.
The available adjustment range depends on the speaker dimensions, diaphragm, suspension, voice coil, magnetic circuit, enclosure, and amplifier.
For more accurate development, it is helpful to provide the target SPL, listening distance, frequency range, amplifier output, and enclosure conditions.
Yes. A project can include more than the speaker driver itself.
ZEH Audio can evaluate integrated solutions including custom speaker enclosures, protective grilles, wire harnesses, connectors, acoustic sealing components, and amplifier matching according to the product assembly requirements.
This can reduce additional assembly work and help ensure that the speaker module fits the finished product correctly.
