PROBLEM TO BE SOLVED: To provide a speaker diaphragm used for acoustic equipment which can have characteristics and sound quality controlled with high precision, a speaker, electronic equipment, and a device. SOLUTION: As an embodiment of the present invention, the speaker diaphragm is constituted by binding a material obtained by mixing at least a resin material and aramid fiber together with an organosilicon compound and carrying out injection molding. Consequently, the diaphragm is obtained which has large flexibility of physical property value setting of the diaphragm, has high elasticity and high internal loss, can secure moisture resistance reliability and strength, and further has superior outward appearance and improved productivity and size stability.
