description The utility model discloses a washer with good wear resistance, which belongs to the technical field of horn assembly process, and is characterized by comprising a washer body, an elastic bulge is arranged in the middle of the washer body, the elastic bulge is a turnup facing the outer side of the washer body, a fixing hole is arranged on the inner side of the elastic bulge, and the elastic bulge is provided with a through hole. The outer wall of the side, close to the fixing hole, of the elastic protrusion is a convex curved surface, the elastic protrusion arranged on the washer body is clamped in a lower side groove of a loudspeaker box frame, the compressed elastic protrusion generates interaction of force, the counter-acting force of the box frame to the elastic protrusion is fed back to the washer body, and meanwhile the elastic protrusion is clamped in the lower side groove of the loudspeaker box frame. The elastic force reinforcing mechanism at the bottom of the washer body interacts with the force gen
