"BGM" Sound / smart device

People are always accustomed to having a background music when they work, study, and entertain. It may be a piece of music, or a film dubbing, or something else. "BGM Sound" is based on this habit of the user and is connected to the home environment intelligently.
The "BGM Sound" speaker does not have complicated operation buttons and interactive forms, it is only a carrier of background music. When it is turned on, it may be a melodious piano song, or it may be a passionate rock music. It is not a definite result, but an indeterminate and eternal process.
