Abstract

PURPOSE:To reduce the cost together with obtain the complete overall oscillation, by means of counterposing paired magnet units of which both parts of magnetized are formed in a whirlpool type and possess the sound induction hole so as to put their together to put their magnetized pattern, together thereby inserting the oscillation plate which possesses the identical shape with non-magnetized section between them.
