The Car Audio Speaker and Woofer speaker Applications
Car audio speakers function as the “fundamental sound transducers” of vehicle audio systems, covering most audio frequency bands to meet core demands like daily music playback and radio reception. Subwoofers, by contrast, serve as “low-frequency enhancers”—they specialize in the 20Hz–200Hz low-frequency range, compensating for the inadequate low-frequency extension of standard car audio speakers. Both products feature extensive application scenarios, detailed as follows:
Car audio speakers are ideal for safety warning scenarios, thanks to their strong sound penetration and high volume output.Sound Pressure Level (SPL): Ranges from 110–130 dB (80–95 dB for small-sized variants), ensuring clear penetration through complex noise such as wind and rain.Low-Frequency Performance: Operates at ≤50 Hz (≥100 Hz for small-sized variants), enabling early warning detection 3–5 seconds in advance from 50 meters away and reducing response latency by 1–2 seconds.Smart Integration: Supports ADAS (Advanced Driver Assistance Systems) linkage, automatically switching warning sounds based on vehicle speed.
High-power car speakers stand out for easy installation and robust stability, making them well-suited for onboard equipment.System Compatibility: Works with CAN/LIN buses, enabling seamless linkage with in-vehicle infotainment systems and active noise cancellation (ANC) systems.Installation Flexibility: Features an ultra-thin magnetic circuit (≤35 mm), compatible with various vehicle models for hassle-free fitting.Durability: Withstands temperatures from -40℃ to 85℃, uses corrosion-resistant silver-plated voice coils, and has an MTBF (Mean Time Between Failures) of ≥5000 hours (2000–3000 hours for small-sized variants).
Properly sized audio speakers deliver superior sound quality and high power-handling capabilities for professional audio setups.Acoustic Performance: Offers a diaphragm stroke of 15–20 mm (≤8 mm for small-sized variants), supports deep low frequencies of 30–50 Hz, and has a frequency response fluctuation of ≤3 dB—boosting cabin sound field uniformity by 20%.Power Capacity: Rated power ranges from 50–500 W (peak power: 300–1000 W), withstanding high-power drives. It is suitable for high-end applications like marine audio, square public address systems, and large machinery.
Speakers with over 500 W power excel in industrial scenarios, thanks to their strong adaptability and harsh-environment resistance.Performance Specifications: Compatible with 500–1000 W power amplifiers, outputs 120–150 dB, and supports unit array configuration—meeting long-distance warning needs for engineering vehicles.Environmental Resistance: Boasts IP68 dustproof and waterproof ratings, anti-magnetic properties (magnetic flux leakage ≤5 mT), and 1.5-meter drop resistance, with a service life of over 10 years.
The Car Audio Speaker and Woofer speaker Advantages
With years of dedication to the automotive acoustics field, the company’s core advantages in manufacturing automotive speakers and subwoofers are prominent:
The speakers adopt neodymium-iron-boron high-density magnetic steel transducers, with magnetic density increased by 35% compared to traditional products, delivering strong treble penetration and high vocal reproduction accuracy. The subwoofers are equipped with a long-stroke composite damper design, enabling a low-frequency extension depth of up to 35Hz, fast transient response, and no muddy distortion. They are suitable for complex acoustic environments such as automobiles, large audio equipment, and large industrial equipment.
Key components include Kevlar fiber cones and waterproof nickel-plated terminals, which can withstand high and low temperature cycles from -40℃ to 80℃ and resist 95% humidity erosion, meeting the IP68 protection standard in the automotive industry. The entire production process is certified by IATF16949, and each product undergoes a 200-hour continuous aging test, resulting in a factory failure rate of less than 0.3%.
Modular customization is supported, allowing parameter adjustments based on the door panel space and power supply system of sedans, SUVs, and new energy vehicles. The interfaces are compatible with the original installation positions of over 80% of mainstream automakers, eliminating the need for additional modifications and reducing automakers’ assembly costs. Meanwhile, the products balance sound quality performance and durability, meeting both end-users’ demands for in-vehicle sound effects and automakers’ requirements for component stability.
FAQs
1. Selection Based on Size and Structural Advantages: Currently, large-size diaphragms ranging from 6 to 15 inches are the mainstream choice. Most diaphragms are made of polypropylene (PP) composite material or Kevlar fiber. PP material is resistant to high and low temperatures and moisture, allowing it to adapt to the complex in-car environment (such as exposure to intense sunlight in summer and low temperatures in winter) and prevent issues like diaphragm deformation. Kevlar fiber, on the other hand, combines high rigidity and light weight, resulting in less distortion during vibration and more solid bass extension. All materials can be customized according to your requirements.
2. Choice Between Circular or Square (and Selection of 2-way, 3-way, 4-way, or 5-way): Circular speakers offer a uniform soundstage, making them suitable for those pursuing a natural listening experience. Square speakers have strong space adaptability and are fit for compact installation locations. Their diaphragms often use “glass fiber composite paper cones” (which have 30% higher rigidity than ordinary paper cones), with edges matched with high-performance materials like “nitrile rubber surrounds” (which have good elasticity, fatigue resistance, and are less prone to aging after long-term vibration). The housing is made of a “thin metal frame” (to reduce space occupation), and customization is available based on your needs.
3. Selection of Magnet and Copper Material: The larger the magnet volume, the stronger the magnetic field, and thus the louder the sound. For copper material, oxygen-free copper is the optimal choice as it enables lossless transmission. It has a conductivity 15% higher than that of ordinary copper, ensuring low loss and low heat generation during current transmission. This prevents sound distortion caused by unstable current (such as no noise or distortion at high volumes). Additionally, oxygen-free copper is corrosion-resistant, which can prevent copper oxidation due to moisture in the car and extend the speaker’s service life.
4. Priority to Easy-Installation Design: Easy installation not only means simple steps but also needs to balance compatibility and stability.
