## What is a Speaker?
A speaker (also called a transducer) is an electronic component that converts electrical signals into sound waves. It consists of core parts including magnet, voice coil, and diaphragm. When current passes through the voice coil, it creates a magnetic field that drives the diaphragm to vibrate, producing sound.
> Speakers are widely used in: headphones, intercoms, learning machines, projectors, smart home devices, laptops, automotive electronics, medical equipment, and more.

## 7 Key Parameters for Choosing Speakers
### 1. Impedance
Impedance is the resistance of the speaker to current, measured in Ohms (Ω).
| Impedance | Best For |
|----------|----------|
| 4Ω | High-power devices, amplifiers |
| 8Ω | General use, home theaters |
| 16-32Ω | Portable devices, headphones |
**Expert Tip**: Choose 4Ω speakers for high-power output; 16Ω or 32Ω for portable devices.
### 2. Power
Power determines the speaker's loudness.
- **Rated Power**: Safe power for long-term operation
- **Max Power**: Maximum power the speaker can handle briefly
### 3. Sensitivity
Sensitivity indicates speaker efficiency, measured in dB.
- Higher sensitivity = better efficiency
- Common range: 85-95dB
- High sensitivity products consume less power
### 4. Frequency Response
The human ear can detect sounds from 20Hz to 20kHz. Consider:
- **Bass**: Low-frequency extension capability
- **Treble**: High-frequency extension
### 5. Size
Speaker size directly affects acoustic performance:
| Size | Characteristics |
|------|-----------------|
| 15-23mm | Ultra-thin, for portable devices |
| 24-36mm | Multimedia, versatile |
| 40mm+ | High-power, excellent bass |
### 6. Diaphragm Material
| Material | Characteristics |
|----------|-----------------|
| PEN | High-temperature resistant, for premium applications |
| PET | Good toughness, cost-effective |
| Composite | Excellent overall performance |
| Cloth+Paper | Traditional, warm tone |
### 7. Waterproof Level
For outdoor or humid environments:
- IPX5: Splash resistant
- IPX7: Brief water immersion
