Description
technical field [0001] The invention relates to the technical field of sound cards, in particular to an external sound card with bluetooth transmission function and convenient adjustment of music mode. Background technique [0002] External sound card, also known as USB sound card. A built-in sound card that is different from the motherboard integration, or connected to the motherboard through PCI, ISA, PCI-E and other interfaces. Like the built-in sound card of the PCI interface, the external sound card also has the difference between a soft sound card and a hard sound card. The external soft sound card is actually the same as the soft sound card integrated on the motherboard, but because the external sound card can use a better CODEC than the motherboard integration, and can add new circuits, the external soft sound card can achieve better sound quality with more functions. The external hard sound card has its own independent audio control chip. The difference between i...
