There are words that | millet MIX 2 officially released, Lei Jun said that millet led the development of a full-screen mobile phone, what do you think?

At 2 PM yesterday afternoon, Xiaomi held a major product launch event in Beijing. The highlight of the conference was undoubtedly the Xiaomi MIX 2, which had been highly anticipated since September. After months of speculation, the new flagship finally made its official debut. Positioned as a business-oriented flagship, the Xiaomi MIX 2 continues to showcase the series’ signature full-screen design, which has become a defining feature of the brand. Priced at 3,299 yuan, the device is expected to attract both tech enthusiasts and professionals. The MIX 2 features a stunning 5.99-inch custom 18:9 rounded glass display. On the front, you'll find the camera module and antenna integrated into the bottom area, while the top houses an ultrasonic sensor. The body is crafted from four-curved ceramic material, paired with a 7-series aluminum frame, and includes a rear-mounted fingerprint sensor for secure access. During the event, Xiaomi's CEO Lei Jun emphasized that the company was the first to introduce the concept of a "full-screen" phone, leading the industry toward this innovative design. He expressed confidence in the MIX 2, even comparing it directly to the upcoming iPhone 8. In a humorous yet insightful moment, he shared a netizen’s cartoon on a slide, illustrating the differences between the full-screen designs of the Xiaomi MIX, Samsung S8, and iPhone 8. After the event, several comparisons were made between the Xiaomi MIX 2 and the Samsung Galaxy S8. Fans and tech lovers are now debating which one looks better. Some argue that the MIX 2’s unique design gives it an edge, while others praise the S8 for its refined aesthetics and performance. As the competition in the smartphone market heats up, Xiaomi continues to push boundaries with its bold design choices. Whether or not the MIX 2 truly leads the full-screen trend is still up for discussion, but one thing is clear — it has sparked a lot of conversation. What do you think? Does Xiaomi’s vision of a full-screen future hold up?

Power Amplifiers

A power amplifier (PA) is a critical audio component designed to take weak audio signals from pre-amplifiers, mixers, or source devices and boost them to levels capable of driving speakers, delivering loud, clear, and dynamic sound. As the final stage in an audio chain, power amplifiers are essential in everything from home stereos to massive concert systems, balancing raw power with precision to ensure audio integrity.
 

Class AB Amplifiers

  • Operation: Combines Class A and B, with transistors conducting slightly more than 180° to reduce crossover distortion.
  • Efficiency: Good (60–70%), balancing sound quality and power consumption.
  • Sound Quality: Low distortion (<0.05%), widely used in home theaters and hi-fi systems.
  • Applications: Home audio systems, studio monitors, and mid-range PA systems.

Class D Amplifiers

  • Operation: Uses Pulse Width Modulation (PWM) to switch transistors fully on/off.
  • Efficiency: High (80–95%), generating minimal heat and requiring smaller heatsinks.
  • Sound Quality: Modern designs achieve <0.1% distortion, comparable to Class AB.
  • Advantages: Lightweight, compact, and energy-efficient.
  • Applications: Car audio, portable speakers, subwoofers, and large-scale PA systems. 
 
Applications Across Industries
1. Home Audio
ï‚·Use Cases: Powering bookshelf speakers, floor-standing speakers, or subwoofers in 2.1/5.1 systems.
ï‚·Example: A 2-channel Class AB amp (100W x2) paired with a CD player and stereo speakers for music playback.
2. Professional Audio
ï‚·Live Events:
ï‚·Large-scale concerts use multi-channel Class D amps (e.g., 4x1000W) to drive line array speakers.
ï‚·Features like bridge mode (combining channels for mono subwoofer power) are critical.
ï‚·Installed Systems:
ï‚·Commercial spaces (hotels, schools) use 70V line amps for distributed audio, ensuring consistent volume across zones.
3. Automotive Audio
ï‚·High-Power Setups: Class D amps (e.g., 2000W mono for subwoofers) deliver deep bass from car batteries (12V systems).
ï‚·Space-Saving Design: Compact Class D modules fit under seats or in trunks without excessive heat.
4. Studio Monitoring
ï‚·Precision Amplification: Class AB amps with low THD (<0.01%) ensure accurate sound for mixing and mastering.
Nearfield Monitors: Dedicated amps for small speakers placed close to the listener in recording studios. 
A power amplifier is the backbone of any audio system, translating electrical signals into the sound that entertains, informs, and moves audiences. Whether delivering subtle nuances in a jazz recording or the thunderous bass of a rock concert, its ability to balance power, efficiency, and precision makes it indispensable in the world of audio engineering.
