Abstract

The present invention discloses a speaker having a structure for prevention of bobbin deformation so that the sound quality can be improved and fabrication and size change can be facilitated. The disclosed speaker comprises a base frame, a vibration plate that is coupled to the top of said base frame, a magnetic body for which a yoke coupled to said base frame is joined at the bottom of said base frame with a magnet fixed inside said yoke, and a plate is fixed to the top of a magnet opposite said yoke, and which is combined with said base frame, a bobbin that has a voice coil wound onto its outer circumference and is inserted vertically from the top of said magnetic body and between the outer part of said plate and the inner part of said yoke and coupled to said vibration plate, and a damper that is connected with the bottom of said bobbin and said magnetic body to prevent deformation of the bottom of said bobbin. Thereby, changes in bobbin shape can be effectively prevented and speakers of various sizes can be fabricated. In addition, the thickness and width are remarkably improved in fabricating a speaker of a given output. In addition, the vibration plate size for a speaker of a given size can be significantly enlarged.
