ABSTRACT:
In the speaker system, an acoustic pipe for conducting a sound wave is arranged in front of a speaker for reproducing a middle and low frequency sound. The acoustic pipe has a rectangular open end portion. A speaker for reproducing a high frequency sound is disposed within the acoustic pipe coaxially with and in front of the speaker for reproducing the middle and low frequency. With this construction, attenuation of middle and high frequency components of sound signals which are produced from the middle and low frequency sound reproducing speaker is suppressed. Moreover, it is possible to conduct the high and middle frequency components and a high frequency component, which is reproduced by the high frequency sound reproducing speaker, as naturally composed sound signals to the open end portion of the acoustic pipe. The speaker system thus exhibits excellent characteristics in sound image localization and articulation of sound, thereby providing a high tone quality to the TV. The TV may be miniaturized with the speaker system.
