Diaphragm for speaker, method of manufacturing same, and speaker

摘要

Provided is a diaphragm for use in a speaker that is configured to include a nanoweb that is formed by electrospinning a polymer material and accumulating nanofibers, so as to have a plurality of pores through which air can pass. The diaphragm can be made thin, have excellent flexibility, have sufficient strength to endure sound pressure, and enhance sound quality of low pitched bands.

主权项

1. A speaker diaphragm, the speaker diaphragm comprising:
a vibration main body made of a polymer nanofiber web and generating sound by vibration of the polymer nanofiber web; and a plurality of pores formed on the vibration main body, wherein the polymer nanofiber web includes a first polymer nanofiber web and a second polymer nanofiber web laminated on the first nanofiber web, the first polymer nanofiber web being formed of a first polymer nanofiber having a first diameter and the second polymer nanofiber web being formed of a second polymer nanofiber having a second diameter smaller than the first diameter.
