Abstract

This invention provides a speaker installed in a TV set and having an improved internal structure to amplify front wave and back wave in two frequency bands, thus preventing distortion of reproduced sound. In this speaker with an enclosure (22), an upper speaker unit (24) and a lower speaker unit (26), a back wave output duct (28) and a lower speaker unit (26), a back wave output duct (28) for upper speaker unit bent to the rear with a given curvature is formed, and a back wave output duct 30 for lower speaker unit is connected to the duct (28)'s inside end within the enclosure (22) and separates back waves each output to the rear of the upper and lower speaker units (4 and 26)
