Small size 4 inch and bigger color LCD monitors are more affordable these days. I think most audio-only devices like stereos, MP3 players, smart speakers, and surround sound speakers may come with a small color LCD screen to show information like the sound volume, or use the screen to display a video file or an app to show the time, weather, song title, subtitles, and temperature.
Smartphone, tablets, smart TVs, laptops, and MP4 video and app players like the iPod Touch can do most smart speaker task, and are starting to have better speakers which have louder volume, and clearer sound, so many people may use the speakers which are built-into their smartphone, tablet, Smart TV, laptop, etc.
