Loudspeaker system, method and apparatus of manufacturing the same
A liquefied paper material is used as raw materials. A paper frame member 1 supporting a vibrating plate is paper-skimmed and formed. On paper-skimming and forming, a central hole for use in voice coils, air-release hole 1 a releasing air pressure in a rear of the vibrating plate to outside due to vibration of the vibrating plate. A loudspeaker system is manufactured using the paper frame member 1.
1. A loudspeaker system, comprising:
a vibrating plate, producing sound due to change in air pressure based on vibration; and
a paper-skimmer and formed paper frame member supporting the vibrating plate in a rear direction of the vibrating plate and having a hole releasing air pressure in a rear of the vibrating plate to outside due to vibration of the vibrating plate, wherein one or both sides of the paper frame member is surface-processed with resin films.
2. A loudspeaker system according to claim 1 , wherein the paper frame member contains thermoplastic resin fibers.
