# Industrial Specification: Sound Generator

## 1. Technical Definition
An electronic or electromechanical device that produces audible warning signals as part of an alarm system.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **85-110 dB(A) at 1 meter, 12-24 VDC operating voltage, -20°C to +70°C ambient temperature**. Failure boundary: **Sound pressure level drops below 80 dB(A) at 1 meter, voltage input exceeds 28 VDC, voice coil temperature reaches 180°C**, Mechanism: **Voice coil overheating due to joule heating (P=I²R) exceeding thermal dissipation capacity, piezoelectric crystal depolarization above Curie temperature (120°C for PZT-5A), diaphragm material fatigue at 10⁷ cycles**.

### 2.1 Analytical Physics Model
Governed by the **Harmonic Vibration Force Generation**:

> **Primary Equation**: $F_e = m \cdot r \cdot \omega^2 \sin(\omega t)$
