(In recent years, public broadcasting systems have been widely used in different public places. Public broadcasting can have an impact on the minds of consumers, which will affect consumers' spending hobbies and habits, the happy mood that music brings to customers, and the construction of music venues. The comfortable and elegant environment will bring more economic benefits to the merchants, and more and more merchants will build and transform the background music system as an infrastructure in order to provide better services for the guests.)
