I divided audio into four times: Traditional plug-in Audio-Bluetooth Audio-WiFi audio-smart audio.
Traditional plug-in audios: Traditional audios must use cables and other input sources. This kind of audio is currently the most popular in the market.
Bluetooth Speaker: via Bluetooth wireless, mobile phones, computers, and other sources are input to the speaker through Bluetooth. This technology began to develop after 2012.
Wi-Fi audio: due to the low bandwidth of Bluetooth, high-quality audio cannot be transmitted. Therefore, the high bandwidth of Wi-Fi is used for transmission. Wi-Fi audio, strictly speaking, is only an upgraded version of Bluetooth audio.
Intelligent Sound: Smart sound has many concepts, such as Internet smart sound, Android smart sound, and cloud audio. The main feature is that the sound itself runs a general operating system to solve its own source problems. At the same time, you can use mobile phones, tablets, and other auxiliary devices for operation and playback.
After three generations, the fourth generation has been ushered in. The fourth-generation smart audio system runs Android and other operating systems and is programmable. The corresponding app development will spring up in the future. Looking forward!
Fourth-generation audio: Smart Internet audio will surely fire
