NOVELTY - Sound-producing device vibrating membrane comprises silicone rubber membrane layer. The silicone rubber membrane layer contains a network polymer. The network polymer includes a first segment, a second segment and/or a third segment. The first segment is silicone moieties (I). The second segment is a fluorine-containing segment (II). The third segment is nitrogen- and fluorine-containing segment (III). USE - Used as sound-producing device vibrating membrane. ADVANTAGE - The sound-producing device vibrating membrane: can reduce amount of change in F0 after contacting with oleic acid, and can be used to manufacture products with low F0 requirements. DETAILED DESCRIPTION - Sound-producing device vibrating membrane comprises silicone rubber membrane layer. The silicone rubber membrane layer contains a network polymer. The network polymer includes a first segment, a second segment and/or a third segment. The first segment is silicone moieties of formula (-Si(R1R2)-O-) (I). The second segment is a fluorine-containing segment of formula (-Si(R3R4)-C(F2)-) (II). The third segment is a nitrogen- and fluorine-containing segment of formula (-N(R5)-O-) (III). R1= methyl, ethyl, trifluoropropyl or phenyl; R2= H, methyl, ethyl, trifluoropropyl or phenyl; R3and R4= -F, -CF3, -H or -OCF3; R5= -CF3or -(CF2)α-C(=O)OR6; α = 1 or 2; and R6= -H or -CH3.
