For OEMs designing security devices like intercoms, alarms, and surveillance systems, speaker reliability and performance are critical. High-quality audio components ensure:
Clear Voice Transmission: Essential for emergency announcements in alarms and two-way communication.
Durability: Withstands harsh environments (e.g., outdoor weather or continuous operation).
Space Optimization: Ultra-thin designs (e.g., 40mm speakers) fit compact enclosures without sacrificing output.
Leading manufacturers prioritize <5% distortion and 90dB+ sensitivity-key for intelligible audio in high-noise environments.
Product Spotlight: XDEC-40M08T13NG16 – Optimized for Security Electronics
1. Key Specifications
Dimensions: φ40×5.0mm (ultra-thin profile for space-constrained devices).
Power Handling:
Rated: 2.0W (4V) / Max: 2.5W (4.47V) – balances volume and energy efficiency.
Impedance: 8Ω±15% (DCR 7.2Ω±10%), compatible with common security device circuits.
Acoustic Performance:
Resonance: 600Hz±20% with 96±3dB sensitivity (0.8–1.5kHz avg), ideal for mid-range clarity.
Bandwidth: F0–20kHz (-10dB), covering voice and alert tones.
2. Reliability for Demanding Applications
48hr Stress Test: White noise at 2.0W with zero failures.
Environmental Resistance:
Temperature: -25°C to +60°C operation (storage: -30°C to +70°C).
Humidity: 48hrs at 40°C/90–95% RH.
Drop-Tested: Survives 2x mechanical drops (1m height).
3. Competitive Edge
Low Distortion: ≤5% at 0.1W (1kHz), outperforming generic 40mm speakers in voice clarity24.
Mylar Diaphragm: Enhances moisture resistance for outdoor/alarm use.
Market Trends & Selection Guidance
Google searches for "40mm ultra-thin speaker for intercom" and "8Ω mylar speaker security" highlight demand for compact, rugged audio solutions. Compared to plastic-shell alternatives (e.g., ¥0.34–¥0.60 40mm toy speakers2), this model offers higher power (2.5W) and military-grade durability.
Ideal for:
Alarms: 96dB SPL ensures audible alerts.
Intercoms: Low distortion maintains voice fidelity.
