<P>PROBLEM TO BE SOLVED: To provide a speaker capable of improving input resistance, securing a low-frequency reproduction band, adjusting a high-frequency reproduction band and reducing the size and thickness. <P>SOLUTION: A speaker 1 comprises: a magnetic circuit 3 attached to a center part of a frame 2; a voice coil bobbin 4 supported in a magnetic gap of the magnetic circuit 3; a voice coil 5 wound along an outer peripheral surface of the voice coil bobbin 4; a tinsel wire 6 connected to the voice coil 5; a diaphragm 7 jointed to a forward end portion of the voice coil bobbin 4; and a support member 8 disposed ahead of the diaphragm 7. The diaphragm 7 is jointed to the forward end portion of the voice coil bobbin 4 and the support member 8 is disposed ahead of the diaphragm 7, thereby allowing a low-frequency reproduction band and input resistance to be improved, and a center part of a back surface of the support member 8 is jointed to a center part of the diaphragm 7, thereby allowing a high-frequency reproduction band to be adjusted. <P>COPYRIGHT: (C)2012,JPO&INPIT |
