DESCRIPTION JPS54100717
BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a view showing the structure of a dome
diaphragm according to the present invention, FIG. 2 is a frequency characteristic diagram of a
speaker having a conventional dome diaphragm, and FIGS. 3 and 4 These are the frequencycharacteristics figures of the speaker which comprises the dome diaphragm of this invention. 1 is
a diaphragm base cloth, 2 is an inorganic minute hollow sphere, 3 is a viscoelastic resin layer.
