Problems solved by technology

[0003] It is undeniable that the existing accompaniment equipment is not only bulky and cumbersome, so it can only be fixedly placed in specific places such as the living room at home or the meeting room in the factory.
In addition, the existing accompaniment equipment cannot be driven by sufficient power provided by ordinary batteries, so it is also limited by the location of the power supply, that is, it must be placed near the power outlet (socket)
In particular, the existing accompaniment equipment must be used with a TV screen, which hinders its convenience in use
As for the price considerations, since the existing accompaniment equipment uses Video-CD or Universal Digital Disc (DVD) as the recording medium, it is necessary to use an expensive decoder and a complex and sophisticated CD player servo drive system
