Patent ID: 11716582

Abstract:
A method for manufacturing a loudspeaker vibrating membrane with hard and elastic soft properties, comprising: (a) adhering a curable polymer to all areas on the outer surface of a base material; (b) drying the curable polymer to form a hard structure; (c) forming a loudspeaker vibrating membrane; and (d) separating the loudspeaker vibrating membrane from the base material. The method further comprises the following steps between steps (b) and (c) or steps (c) and (d), or after step (d): (e) adhering an elastic soft polymer to all or partial areas on the outer surface of the hard structure; and (f) drying the elastic soft polymer to form an elastic soft structure covering all or partial areas on the outer surface of the hard structure. In the present invention, the hardness and elastic coefficient of the loudspeaker vibrating membrane can be adjusted by the hard structure and the elastic soft structure.
