Abstract

A speaker (100, 700, 100A, 100B) includes a magnet main body (210, 810, 210A, 210B) and a yoke (220, 230, 820, 830, 220A, 220B, 230A, 230B) magnetically linked to a first magnetic pole of the magnet main body. The speaker also includes a diaphragm (400, 400A, 400B) having a vibratory section (410, 410A, 410B), an edge section (430, 430A, 430B), and a rising section (420, 420A, 420B) between the vibratory section and the edge section. A magnetic body (300, 900, 300A, 300B) of the speaker is magnetically linked to the yoke, facing the magnet main body and a voice coil (500, 500A, 500B) is wound around the rising section of the diaphragm. The magnetic body includes an inner shell (330, 330A, 330B), an outer shell (310, 310A, 310B) and a bridge section (320, 320A, 320B) between the inner shell and the outer shell to cover the edge section of the diaphragm. The inner shell of the magnetic body extends from the bridge section along the rising section and the vibratory section of the diaphragm within the inner shell. A magnetic gap (G) is formed between the inner shell of the magnetic body and the magnet main body and the rising section passes through the magnetic gap.
