| titleOfInvention | Speaker diaphragm, speaker using the same, and electronic device and apparatus using the speaker |
| abstract | The present invention relates to a loudspeaker diaphragm used in various audiovisual equipment and a loudspeaker using the loudspeaker, and it has been a problem to improve sound pressure in a high sound range and expand a reproduction band. . A speaker diaphragm according to the present invention is a speaker papermaking diaphragm using at least 5 wt% of a fiber extracted from bamboo leaves, and is contained in a plant that is frequently present in bamboo leaves including straw. By using the fiber from which the silicon dioxide compound is extracted for the papermaking diaphragm, the rigidity of the papermaking diaphragm is improved, and the sound pressure is improved in the high sound range of the speaker and the reproduction band is expanded.
