Abstract: The present invention relates to a subminiature bone conduction speaker by using a vibrating plate and a mobile phone having the subminiature bone conduction speaker.

Abstract: The present invention relates to an interconnect device for a printed circuit board, a method of manufacturing the same and an inter-connect assembly having the same. According to one aspect of the present invention, the interconnect device for a printed circuit board comprises: a first contact section 10 having a bar-like shape for making contact with a second contact terminal 76 in a space transformer 52; a connecting section 12 having an O-ring-like shape of which one side is opened and connected to one end of the first contact section 10 in an integrated manner; a support section 14 having an engaging protrusion 14a in a predetermined portion and connected to one end of the connecting section 12 in an integrated manner; and a second contact section 16 having an O-ring-like shape and connected to one end of the support section 14, wherein the whole inter-connect device is made up of an identical resilient material.

Abstract: Disclosed herein are a probe and a method of making the same, and more particularly to a probe having a minute pitch, with which a probe card corresponding to arrangement of pads formed with a massed shape or other various shapes on a wafer is made, and a method of making the same. The probe having a prescribed thickness and formed in the shape of a flat plate. The probe comprises a body part bent at the middle thereof so that the body part is elastically tensioned or compressed when a tension force or a compression force is applied to the body part at the upper and lower ends thereof, a connection part integrally formed with the lower end of the body part, the connection part being fixed to a substrate, and a tip part integrally formed with the upper end of the body part, the tip part contacting a pad of an element.
