Document Type and Number:
WIPO Patent Application WO/2014/038102
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a speaker that exhibits high performance in reproducing original sound. In this speaker (10), the end part of a bobbin (24) on the opposite side from the bobbin end part around which a coil (48) is wound extends outwardly in the radial direction of the bobbin (24), and the flange part (52) formed from this extended part is bonded to a vibrating part (21) with a bonding agent (BND). Thus, sufficient bonding strength can be ensured by thin application of the bonding agent (BND) to just the area between the flange part (52) and the contacting part (21) of the vibrating part (21).
