Title:
SURFACE MOUNTED VIBRATION MOTOR AND MOUNTING STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2006/104003
Kind Code:
A1
Abstract:
[PROBLEMS] A surface mounted vibration motor which prevents the floating phenomenon of a metal holder or a metal housing case at solder melting at the time of solder reflow processing and is not likely to cause positional deviation, and a mounting structure. [MEANS FOR SOLVING PROBLEMS] A surface mounted vibration motor comprising a vibration motor having an eccentric weight attached to the rotary shaft, a metal holder that holds the trunk of the vibration motor body to be solder-joined to a fixed area for mounting on a circuit board side, and a pair of feed terminals for energizing a rotation drive mechanism inside the vibration motor body, characterized in that a plurality of protruding convex rails extending in the axial direction of the rotary shaft or a plurality of semi-spherical protrusions are disposed on the bottom surface of the metal holder that holds the trunk of the vibration motor body to contact and be solder-joined to a fixed area for mounting on a circuit board side.
