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.
Wider Audio Coverage: Supports voice, background music, video sound effects, and system notification tones to meet a wide range of audio playback requirements.
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. 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.
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.
The size should be neither too large nor too small, and the speaker should produce loud sound without distortion.
As the most critical component for sound reproduction, a speaker needs to precisely balance two core requirements: compatibility with the enclosure size and acoustic performance. The right audio speaker should be matched based on the customer’s actual enclosure size and the power of the PCBA board. To achieve “loud sound without distortion” in terms of acoustic performance, focus on the speaker’s core configuration: use a high-purity copper voice coil to improve energy conversion efficiency, pair it with a neodymium-iron-boron strong magnet to enhance driving force, and adopt a composite fiber diaphragm to optimize vibration stability. At the same time, customize a sealed sound cavity according to the in-vehicle environment to reduce cabin resonance interference. This not only meets the need for clear sound amplification during driving but also avoids noise and distortion at high volumes.
If the enclosure is already formed (e.g., fixed mold, limited installation space), targeted adjustments can be made to the speaker size, or a custom-shaped speaker that fits the enclosure cavity can be developed to achieve precise integration without modifying the enclosure. Additionally, optimize the speaker’s acoustic structure to compensate for enclosure defects (such as sound leakage caused by insufficient sealing). If the enclosure is still adjustable, its structure can be optimized according to the size and acoustic requirements of the target speaker, fundamentally solving the compatibility issue.
The speaker power can be accurately matched to the set parameters of the PCBA power amplifier, with the core goal of achieving “sound optimization + performance compatibility”. ZEH’s professional PCBA acoustic engineers first accurately measure core parameters of the power amplifier, such as rated power and output impedance. Then, they adjust key indicators of the speaker—including the number of voice coil layers, magnetic strength, and diaphragm rigidity—to ensure perfect matching between the speaker power and the PCBA power amplifier. This not only avoids distortion and noise caused by power mismatch but also maximizes the performance of the power amplifier, achieving dual optimization of volume and sound quality. Engineers will also conduct targeted tuning based on the product’s actual usage scenarios (e.g., noisy environment, installation location) to ensure the final acoustic performance meets the product’s requirements.
