The present invention discloses a three-dimensional sound guide for a speaker, and a speaker having the same. The three-dimensional sound guide for a speaker according to the present invention is provided inside a circular or oval horn, wherein the lower part has a reverse circular cone shape with a curved surface corresponding to an inner side surface of the circular or oval hone so as to provide a guide groove which is a path where sound is transmitted on the inner side surface of the circular or oval hone, and the upper part has a round shape surface. An edge unit where the upper part and the lower part of the three-dimensional sound guide for a speaker meet is provided to come into contact with the upper part of the inner side surface of the circular or oval hone. The three-dimensional sound guide for a speaker is realized by sound transmission materials that transmit the sound, wherein the sound that passes through each of a path transmitted along the guide groove and an arbitrary path transmitted through the inner part of the three-dimensional sound guide for a speaker has the same time transmission path with respect to a plane based on the peak of the round shape surface. |
