| titleOfInvention | Speaker diaphragm |
| abstract | (57) [Summary] (Correction) [Constitution] A speaker diaphragm made of a warp or a weft made of a synthetic fiber or a natural fiber and a weft or a warp made of a thread-like material obtained by chopping a warp sheet. [Effect] 1. Since natural wood is used in its natural state, comfortable natural sounds can be obtained for the human ear that cannot be measured with data. 2. Since the material with low specific gravity required for the diaphragm can be freely selected, a material with low density and high elastic modulus can be obtained, and the sound quality can be improved. 3. Since it can be woven with a loom, uniform products can be mass-produced in a short time according to need. Therefore, it is possible to mass-produce a high-quality, low-priced, lightweight and tough diaphragm material. 4. The materials are always available and easy to manufacture. |
