The present invention relates to a dust cap for a speaker, a speaker, an electronic device, and an apparatus used for an audio device, and improvement in sound quality and improvement in adhesion are problems. In the present invention, a speaker dust cap is formed by injection molding a material in which at least a resin material and a pulp material are mixed, thereby improving the sound quality and increasing the degree of freedom in setting the physical property value. Configuration that can realize a dust cap that can take advantage of both the advantages of good paper, moisture resistance reliability and strength, excellent appearance, and the advantages of resin that can improve productivity and dimensional stability It is what.
