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 injection-molded using a material obtained by mixing together resin, aramid pulp, and microfabril aramid pulp obtained by making the aramid pulp fine into a microfabril state. 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.
