Abstract

PURPOSE:To increase the strength and lower the respnance sharpness of the diaphragm, by producing the speaker cone paper through mixture of the pineapple fiber. CONSTITUTION:The diaphragm is formed with the paper which is made by using a plant fiber pulp of the ananas family such as the pineapple fiber having a large fiber length and a small fiber width each. In that case, the paper diaphragm of only such plant fiber pulp of the ananas family can also be formed. Otherwise the same plant pulp can be mixed with other ordinary pulp to be used for the diaphragm. The diaphragm made of such plant fiber pulp of the ananas family has a high Young's modulus and a low resonance sharpness (Q-value).
