Title: Speaker
Inventor: KOIKE TOSHIYUKI
IPC: H04R9/02
Filed: 2010-07-15
Abstract: PROBLEM TO BE SOLVED: To prevent frame deformation and magnetic circuit deviation, caused by heat generated from a voice coil, in a speaker having a structure of a magnetic circuit coupled in a lower portion of the frame.SOLUTION: A magnetic circuit 24 is housed in an enclosed manner inside a frame 26. A recess 26a is formed on a storage internal wall of the magnetic circuit 24 on the frame 26. By coating or filling an adhesive 26b on the recess 26a, the lower portion of the magnetic circuit 24 is received by the lower portion of the magnetic circuit storage. Also, heat transmission from the magnetic circuit 24 to the frame 26 is reduced by an increased amount of the adhesive 26b that couples the frame 26 with the magnetic circuit 24. By the shape of the adhesive 26b when it is solidified, a wedge shape is formed, and thereby an upward deviation of the magnetic circuit 24 is prevented.
