Abstract
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.
Claims11
A diaphragm for a speaker, the diaphragm comprising:
- a vibration main body made of nanofibers that are formed by electrospinning a polymer material, and that is formed in a nanoweb structure to thus generate sound by vibration;
- and
- a plurality of pores formed on the vibration main body of the nanoweb structure.
A speaker including a diaphragm, the speaker comprising:
- a housing;
- a magnetic circuit having an air gap and that is supported by the housing;
- a coil that is displaceably positioned in the air gap of the magnetic circuit;
- a vibration main body that is vibrated according to displacement of the coil, that is made of nanofibers that are formed by electrospinning a polymer material, and that is formed in a nanoweb structure to thus generate sound by vibration;
- and
- a plurality of pores formed on the vibration main body of the nanoweb structure.
3 more elements
A method of manufacturing a diaphragm for a speaker, the method comprising the steps of:
- mixing a polymer material and a solvent at a certain mixture ratio, to thus prepare a spinning solution;
- and
- electrospinning the spinning solution to create nanofibers and accumulating the nanofibers, to thus form a vibration main body having a plurality of pores and that is formed in a nanoweb structure to thus generate sound by vibration.
