The invention relates to the field of smart clothing sport monitoring, and in particular to a signal processing apparatus and a smart clothing. The signal processing apparatus at least includes: a fixing seat, a line board connecting module, a function module, and a top cover. The line board connecting module and the function module are disposed between the fixing seat and the top cover. The fixing seat is used for fixing to the smart clothing and is provided with a first through hole thereon. The line board connecting module is provided with a first end surface relative to the fixing seat and a second end surface relative to the function module. The first end surface is used for connecting a wire which passes the first through hole. The second end surface is provided with a conductive buffering structure thereon which is connected to the wire. The conductive buffering structure is in electrical connection with the function module.
