Abstract
A USB power amplified trumpet connecting device comprises a digital conversion chip and a power amplifier chip on a circuit board; an input connected to a USB port as an input; and an output. The output is connected to one of an earphone, a trumpet, or an optical fiber terminal. The output seat is an optical output seat which is connected to an optical fiber terminal for further connecting to a decoding amplifier and then to a trumpet. Another the output can be an output wire; and the output wire is connected to a trumpet. The output is an output seat; and the output seat is able to output cable signals and optical fiber signals for being connected to one of an earphone, a trumpet and an optical fiber terminal.
