Title:
SENSORY SIGNAL OUTPUT APPARATUS
Document Type and Number:
WIPO Patent Application WO/2010/123169
Kind Code:
A1
Abstract:
The present invention relates to a sensory signal output apparatus which comprises: a magnetic circuit package which vibrates in response to a coil into which an alternating signal flows; and an elastic supporting unit which elastically supports the magnetic circuit package by enclosing the outer surface of the magnetic circuit packet from one direction. The invention is characterized by: forming coupling grooves at a certain interval on the outer surface of the magnetic circuit package; and preparing coupling pieces which correspond to and are coupled to the coupling grooves at the outer periphery of the elastic supporting unit. The invention provides the convenience in a coupling process by coupling the magnetic circuit packet to the elastic supporting unit through insertion instead of curling. In addition, the invention is able to improve vibration force and middle and low-pitched sound properties by ensuring the maximum size of a magnet and the maximum weight in the magnetic circuit package having a same diameter and a same height.
