Abstract

The surface-mountable linear vibrator comprises a hollow cylindrical housing of a predetermined thickness having a space therein; an elastic member fixed to an inner surface of the housing; a vibrating body including a yoke fixed to the elastic member to be affected by elastic force in an axial direction of the housing, a weight fixed to the yoke, and a magnet fixed to the yoke; and a circular substrate member attached to a lower part of the housing, and provided with a winding coil fixed to the upper surface thereof and connection means formed on the lower surface thereof and electrically connected to the winding coil, wherein power is applied to the winding coil through the connection means. The surface-mountable linear vibrator is installed by an automated process using SMT, improves reliability of connection, and is easily installed in a mobile phone.

Description

[0001] This patent application claims priority to Korean Patent Application No. 2004-49332 filed with the Korean Intellectual Property Office on June 29, 2004, the contents of which are incorporated herein by reference. technical field [0002] The present invention relates to a linear vibrator that generates vibration by causing a vibrating body elastically mounted in a housing to perform translational motion, and more particularly, the present invention relates to a surface-mountable linear vibrator in which a base member is fixed to a lower portion of a housing device. Background technique [0003] Various vibration generators are installed in mobile communication terminals, ie, mobile phones, which are used to generate vibrations used as incoming call destination signals. A vibration motor is generally used as the above-mentioned vibration generator. Each vibrating motor converts electrical energy into mechanical energy, and then uses the mechanical energy to vibrate th...
