Abstract

The invention describes a sound card which comprises a shell, a main control circuit board, a knob, an encoder, a transmission structure and a sound card body, wherein the shell comprises an operation surface and a placement surface which are opposite, the operation surface is obliquely arranged relative to the placement surface, the placement surface is parallel to a horizontal plane, the knob is provided with a first rotating shaft which is perpendicular to the operation surface, the encoder is connected with the main control circuit board and is provided with a second rotating shaft, and the knob rotates and drives the first rotating shaft, the transmission structure and the second rotating shaft to move sequentially. Therefore, the encoder can be directly connected to the main control circuit board, and is not connected through a suspended connecting wire, so that the stability of connection is enhanced, and the influence of electromagnetic interference of other circuits on signal transmission can be reduced. In addition, through the setting of transmission structure, then the first pivot of knob still can be perpendicular to the operation face, makes the user operate more naturally and comfortablely, accords with ergonomic principle.
