Abstract

PURPOSE:To simplify the manufacturing process and to reduce the cost, by using spliced paper tubes for the frame of a speaker. CONSTITUTION:A frame 5 has an axial length slightly shorter than that of a speaker main body and it is a cylindrical shape which has a little shorter inner diameter than the diameter of a cone 7 and a little longer outer diameter. Various cylinders can be used for the frame 5, such as sliced paper tubes with a specified diameter in which craft papers are laminated.
