A speaker housing comprises an enclosing side wall frame and a washer. A portion enclosed by the side wall frame is an inner side of the side wall frame. The washer is integrated with the side wall frame by injection molding, and at least a part of the washer is exposed at the inner side of the side wall frame. A seam is formed between a surface of the washer exposed at the inner side of the side wall frame and a surface of the side wall frame. Recesses are formed in surfaces of the washer and the side wall frame at two sides of the seam. Further provided is a speaker unit comprising the above speaker housing. A technical effect of the present application is to prevent a plastic burr extending from the seam between the washer and the side wall frame from affecting the speaker.
