Abstract
A speaker apparatus includes a frame having a magnetic circuit, a voice coil bobbin installed in the frame to be magnetically coupled to the magnetic circuit, and a diaphragm movably installed in the frame and fixed to the voice coil bobbin so as to be driven by activating the magnetic circuit. The diaphragm has a positioning portion that had been used for securing the diaphragm relative to the magnetic circuit during an installation of the diaphragm in the frame.
Claims25
A speaker apparatus comprising a diaphragm and a magnetic circuit, wherein the diaphragm has a positioning portion for positioning the diaphragm relative to the magnetic circuit.
A speaker apparatus comprising:
- a diaphragm;
- a magnetic circuit;
- and
- a positioning member fixed to the diaphragm for positioning the diaphragm relative to the magnetic circuit.
A method for manufacturing a speaker apparatus comprising the steps of:
- fixing a magnetic circuit to a frame;
- positioning a coil with respect to a center pole of the magnetic circuit,
- connecting a damper to the coil and the frame;
- projecting a jig from a center hole of the center pole;
- engaging a positioning portion provided on a diaphragm with the jig to position the diaphragm at a predetermined position with respect to the center pole;
- and
- connecting the positioned diaphragm to the coil and the frame.
