In devices like security surveillance systems, campus PA systems, and educational smart hardware, clear, stable, and durable audio output is paramount. Selecting the right speaker becomes critical when facing demands for compact spaces, complex environments, and long-term operation. The 30mm Mylar speaker model XDEC-30M08T12NB27, with its balanced performance and reliable quality, has become a preferred solution for many equipment manufacturers.
I. Core Performance: Engineered for Clear Voice & Stable Operation
The core advantages of this speaker are evident in:
Exceptional Clarity & Loudness:
92dB ±3dB Sensitivity: Generates higher sound pressure levels (SPL) at the same input power, ensuring sufficient penetration in environments like classrooms and hallways. Sound remains clearly audible even at the back.
Optimized Voice Frequency Band (390Hz - 5kHz): Rigorously tested to ensure no abnormal sounds within this critical range, guaranteeing clear and natural reproduction of human voices (e.g., announcements, intercom calls, instructional commands).
Effective Frequency Bandwidth (F0 ~ 7kHz): Covers the primary frequency range essential for voice transmission.
Robust Power Handling:
Rated Power: 1W / Max Power: 1.5W: Meets the demands of security and education equipment for continuous playback of voice prompts, background music, or short alarms, providing ample volume headroom.
Outstanding Environmental Adaptability:
Wide Operating Temp Range (-25°C ~ +60°C) & Storage Temp Range (-30°C ~ +70°C): Easily handles extreme cold and heat faced by outdoor equipment, as well as potential high/low temperature environments indoors.
Moisture Resistance (40°C, 95%RH, 24 hours): Effectively withstands humid southern climates or potential condensation inside equipment.
96-Hour Pink Noise Load Test: Simulates prolonged continuous operation, verifying stability and lifespan under constant playback, reducing equipment failure rates.
Compact Size & Ease of Use (Ref. Spec Sheet 1-1):
Ultra-Slim Design: Φ30mm x 4.6mm: Extremely space-saving, ideal for integration into compact devices like video intercom panels, portable educational terminals, and educational robot heads.
Standard 8Ω Impedance (±15%): Easily compatible with mainstream audio amplifier solutions on the market, simplifying circuit design and reducing development difficulty and cost.
Good Solder Heat Resistance (350°C ≤ 3-5 seconds): Suitable for standard PCB reflow soldering processes, ensuring production yield.
II. Why is it Ideal for Security & Education Equipment?
Security Surveillance / Building Intercoms: Clear playback of alarm messages, access prompt tones, and call audio is critical. The speaker's high sensitivity, optimized voice band, wide temperature/moisture tolerance, and stability under long operation ensure clear, intelligible sound in various environments (lobbies, corridors, outdoor units) and long-term durability.
Campus PA / Information Display Systems: Requires coverage of larger areas. The 92dB sensitivity and 1.5W max power provide sufficient sound pressure. The wide frequency response guarantees voice clarity, while environmental adaptability ensures year-round reliable operation.
Educational Robots / Reading Pens: Space is extremely valuable. The 30mm diameter and mere 4.6mm thickness are significant advantages. Mylar diaphragm characteristics (good high-frequency response, lightweight) also help enhance the clarity and naturalness of voice interaction. Strict abnormal sound control ensures pure audio content.
Attendance Terminals / Queuing Systems: Require stable, clear playback of operational prompts. Its reliability, ease of integration, and clarity fully meet these needs.
