In the design of portable Bluetooth speakers, smart speakers, and small public broadcast equipment, balancing sound quality with power consumption remains a core challenge. The 40×20mm multimedia speaker driver from Shenzhen Xuanda Electronics Co., Ltd. addresses this pain point with professional acoustic design, making it an ideal choice for manufacturers seeking high performance and cost optimization.
1. Balanced Frequency Response for Rich Sound
The 40mm driver unit delivers a solid low-frequency foundation, complemented by precise mid-high frequency tuning, achieving a balanced 20Hz-20kHz frequency range. Whether for clear voice reproduction in smart assistants or powerful bass in portable PA speakers, it offers detailed and immersive audio.
2. High Sensitivity for Cost-Efficient Design
Sensitivity ≥85dB, compatible with various amplifier solutions (e.g., Class D digital amps)
Low-impedance options (4Ω/8Ω) reduce power consumption, extending battery life
Optimized magnetic circuit design minimizes heat generation while maintaining dynamic range
3. Compact Size for Multi-Scenario Applications
As the "golden standard" for mini desktop speakers, its compact dimensions (40×20mm) fit seamlessly into:
Voice modules for smart speakers
PC speaker systems
Portable PA speaker arrays
Directional sound fields in public address systems
4. Customization for Product Differentiation
With 15 years of expertise in mid-large size drivers, Xuanda offers:
Custom impedance (2Ω-16Ω)
Frequency response tuning (e.g., enhanced vocal range)
Special diaphragm materials (carbon fiber, bio-cellulose, etc.)
