Patent ID: 7497003

Claim:
A speaker design support apparatus that supports the designing for a speaker provided with at least a voice coil, a magnetic circuit, and a diaphragm, the speaker design support apparatus comprising: input means for inputting design data to design the voice coil, the magnetic circuit, and the diaphragm; coil calculation means for calculating a shape of the voice coil based on the design data of the voice coil; magnetic circuit calculation means for calculating a shape of the magnetic circuit based on the design data of the magnetic circuit; diaphragm calculation means for calculating a maximum excursion and excursion margin of a diaphragm based on the design data of the diaphragm; shape deciding means for deciding whether or not a fixed portion interferes in a vibration of a moving portion, by using the shape of the voice coil, the shape of the magnetic circuit, and the maximum excursion and excursion margin of the diaphragm; and display means for displaying characteristics of the speaker based on the inputted design data, and a calculated result.
