Speakers
1.Speakers: Bringing Sound to Computing A speaker is an output device that converts electrical signals into audible sound. In computing, speakers allow users to hear audio from applications, games, videos, and communication tools. They transform digital information into a sensory experience, making computers not only visual but also auditory machines. This idea is beautifully captured in a famous line from the Hong Kong film Infernal Affairs (2002): “Highs are sweet, mids are accurate, lows are deep — in short, the sound is transparent.” (Original Chinese: 高音甜，中音准，低音沉，总之一句话，就是通透). 2.Historical Background 3.Architecture and Features Speakers vary widely in design, but most share common components: 4.Trends and Future Outlook
