Problems solved by technology

This TV accompaniment music with karaoke often needs to be provided by other external equipment such as VCD, DVD etc., and equipments such as present VCD, DVD often also have karaoke function itself, so cause duplication and waste in function; The accompaniment program source needs to be supplied by purchasing music discs, which is not economical and practical; in addition, due to space and other constraints on TV sets, the power and quality of the sound amplification can hardly achieve the ideal singing effect; and with the development of computer and network technology And popularization, making people more accustomed to the use of network multimedia resources, devices with USB interfaces and other new data interfaces are used by more and more people, while some traditional devices are less and less used
