Based on the provided datasheet, here's a focused analysis of the 30mm Mylar speaker for integration into educational devices, intercoms, and alarms, structured to align with your requested format:
1. Core Performance Parameters
Dimensions: 30mm diameter × 5.8mm ultra-thin profile (ideal for compact devices like point-reading pens).
Impedance: 8Ω±15% (DCR 7Ω±10%) at 2kHz, balancing power efficiency and clarity.
Power Handling:
Rated: 1.5W (3.46V) / Max: 2.0W (4.0V) for sustained mid-range output.
Frequency Response:
600Hz±20% resonance with 90±3dB sensitivity (1500–3000Hz avg), optimized for voice reproduction.
Effective bandwidth: F0–11kHz (-10dB SPL), suitable for alarms and language prompts.
2. Durability & Environmental Tests
Reliability:
96hr white noise load (1.5W, 450Hz–20kHz) with no failure.
Thermal endurance: -25°C to +60°C operating range, -30°C to +70°C storage.
Humidity resistance: 40°C/90–95%RH for 24hrs without degradation.
Mechanical Stress: Passes 6x drop tests and 350℃ solder heat resistance (3–5 sec).
3. Design Integration Tips
Mid-Range Clarity: Mylar diaphragm minimizes distortion (<10% THD at 2kHz) for clear speech in:
Learning tablets: Paired with 8Ω impedance for balanced power consumption.
Intercoms: Waterproof mesh (230目) ensures moisture resistance.
Space Constraints: 5.8mm height fits slim devices (e.g., wearable alarms).
