Abstract:
Sound quality is improved. A speaker device includes: a frame which functions as a housing; a diaphragm which vibrates when sound is outputted; a magnetic circuit which vibrates the diaphragm; and a speaker grille which is attached to the frame, in which the speaker grille is provided with a frame-shaped portion formed into an annular shape and a crosspiece portion positioned at an inner side of the frame-shaped portion and partly continuous with the frame-shaped portion, and the crosspiece portion is formed into a non-concentric shape as well as at least partly formed as a curved portion with a curved shape. Thus, since the crosspiece portion is constituted with the structure having the curved portion in a state in which the constitution with a concentric shape is not present, dips, in particular, hardly occur in the frequency characteristics, and a good output state of sound can be secured.
