[suspension member for speaker]

Abstract

An elastically deformable suspension member for speaker is disclosed to have an inner diameter portion for mounting of a cone, an outer diameter portion spaced around the inner diameter portion at a predetermined pitch for fastening to a basket, and three or more arched surface portions formed in the predetermined pitch and extending one within another around the inner diameter portion and connected between the inner diameter portion and the outer diameter portion for enabling the suspension member to give a sufficient support to the connected cone to prevent distortion during working of the speaker.

1 . A suspension member having a hollow elastic body, said hollow elastic body comprising an inner diameter portion for the mounting of a cone, an outer diameter portion spaced around said inner diameter portion at a predetermined pitch for fastening to a basket, and at least three annular surface portions formed in said predetermined pitch between said inner diameter portion and said outer diameter portion and smoothly arched in transverse direction and extending one within another around said inner diameter portion and connected between said inner diameter portion and said outer diameter portion.  
   
   
       2 . The suspension member as claimed in  claim 1 , wherein said annular surface portions include a first annular surface portion and a plurality of second annular surface portions symmetrically disposed at two sides of said first annular surface portion and respectively connected between said inner diameter portion and said first annular surface portion and between said outer diameter portion and said first annular surface portion.  
   
   
       3 . The suspension member as claimed in  claim 1 , wherein said outer diameter portion has a plurality of equiangularly spaced peripheral notches for mounting the engagement of bottom flanges of a locating ring.  
   
   
       4 . The suspension member as claimed in  claim 1 , which is made of polyurethane.
