Abstract
In a speaker including a voice coil which is wound on a voice coil bobbin and is inserted into a magnetic circuit gap of a magnetic circuit, and a cone which is coupled to the voice coil bobbin for vibration, the cone (16) is constructed of two divided cones: a drive cone (16A) linked to the voice coil bobbin (14) and a cone paper (16B) linked through an edge (17) to a frame (F).
Claims11
A speaker comprising:
- a magnetic circuit having a magnetic circuit gap;
- a voice bobbin;
- a voice coil wound on said voice coil bobbin and inserted into said magnetic circuit gap of said magnetic circuit
- an edge;
- a frame;
- and
- a diaphragm member linked to said voice coil bobbin for vibration and constructed of two divided vibration members of a first divided vibration member linked to said voice coil bobbin and a second divided vibration member linked through the edge to the frame, wherein said first divided vibration member is not directly fixed to the frame, said second divided vibration member is not directly fixed to the voice coil bobbin, and said first divided vibration member and said second divided vibration member are coupled to each other through a connection member.

A method of assembling a speaker, comprising steps of:
- assembling a magnetic circuit part including a magnetic circuit gap;
- mounting a voice coil bobbin, on which a voice coil is wound and which is coupled to a first divided vibration member making up a diaphragm member, to the magnetic circuit part so as to insert a portion of a the voice coil bobbin on which the voice coil is wound into the magnetic circuit gap;
- attaching a frame to the magnetic circuit part wherein the frame is not directly fixed to the first divided vibration member;
- interposing a plurality of dampers between the frame and the first divided vibration member which is mounted to the magnetic circuit part through the voice coil bobbin;
- and mounting a second divided vibration member, which makes up the diaphragm member together with the first divided vibration member, between the first divided vibration member and the frame to which the dampers are attached wherein the dampers are not directly fixed to the voice coil bobbin.
