Patent number: 9479873Abstract: A support chassis mounted on a sounding side of a speaker apparatus is formed of an iron material. The support chassis is formed in a shape in which a central supporting part nears a main-body chassis. A magnetic field generating unit is fixed to the central supporting part on a side of a recess of the support chassis. The support chassis includes a frame part, the central supporting part, and spoke parts. In the spoke part, a width dimension D1 of an inner end part is formed narrower than a width dimension D2 of an outer end part. Therefore, a resistance in a case where a magnetic flux passes through the spoke part increases, and the leaked magnetic field is hardly induced from the magnetic field generating unit to the spoke part. Therefore, a reduction in a speaker output can be prevented.Type: GrantFiled: April 24, 2015Date of Patent: October 25, 2016Assignee: Alpine Electronics, Inc.Inventors: Masaru Yamagami, Arata Tada, Kei Tanabe
