Abstract
Official abstract text for this publication.
A manufacturing method of a vibrator includes processing a tip of a contact part arranged on an elastic body of the vibrator by lapping or grinding processing so that part of the tip has a plane shape in part of a spherical shape.
First claim
Opening claim text (preview).
What is claimed is: 1 . A manufacturing method of a vibrator, the manufacturing method comprising processing a tip of a contact part arranged on an elastic body of the vibrator by lapping or grinding processing so that part of the tip has a plane shape in part of a spherical shape. 2 . A manufacturing method of a vibrator, the manufacturing method comprising processing a tip of a first contact part arranged on an elastic body and a tip of a second contact part arranged on the elastic body by lapping or grinding processing so that each of the tip of the first contact part and the tip of the second contact part has plane shape in part of spherical shape. 3 . The manufacturing method of the vibrator according to claim 2 , wherein the plane of the first contact part and the plane of the second contact part are on a same plane. 4 . The manufacturing method of the vibrator according to claim 2 , wherein the lapping or grinding processing is performed in a format in which the elastic bodies of a plurality of vibrators are attached to a common base member. 5 . The manufacturing method of the vibrator according to claim 2 , wherein the lapping or grinding processing is performed in a format in which a plurality of elastic bodies is integrated and continuous in a sheet shape, the elastic bodies forming a sheet-shaped member. 6 . The manufacturing method of the vibrator according to claim 5 , wherein the sheet-shaped member comprises: the elastic bodies; a frame part; and a connection part connecting the elastic bodies and the frame part, wherein the connection part is on one axis in a substantially perpendicular direction of the arrangement of the contact parts.
