A sound A is emitted from respective left- and right-hand front speakers which are provided on a television set, in a front direction, while, regarding respective side speakers which are provided respectively on left- and right-hand sides of the television set, reflectors each having substantially a semi-conical shape are provided so as to face to a forward direction of one-side faces of respective speaker diaphragms, to radiate sounds B due to the side speakers, in the front direction. In other words, in addition to the sound A in the front direction which are emitted from the left- and right-hand front speakers, the sounds B due to said side speaker are radiated in the front direction at positions at which a sound radiated position is different in vertical direction, and in backward and forward direction from this sound A. Moreover, the arrangement is such that a radiated sound C from the other side faces of the respective speaker diaphragms of the left- and right-hand side speakers to which said reflector does not face is radiated to left- and right-hand outward faces of the television set as it is. Thus, it is possible to improve separation performance of the left- and right-hand sounds, and it is possible to generate sounds having a cubic sound feeling, an expanding feeling and a stereophonic feeling. |

DETAILED DESCRIPTION An object of the present invention is to provide a speaker system for a television set, which is superior in left- and right-hand separation characteristics and left- and right-hand movement feelings and which can reproduce a sound having a stereophonic feeling.
Another object of the invention is to provide a speaker system for a television set, which provides, a good appearance.
According to a first invention, there is provided a speaker system for a television set, which is characterized by comprising: a first speaker arranged within the television set; an acoustic waveguide for guiding sound from the first speaker, to a front direction of said television set and a second speaker provided with a conical reflector arranged on a side of the television set and at a position where a sound radiated position is different in height and depth from the first speaker, for radiating and diffusing the sound to the front direction from the television set.
According to a second invention, there is provided a speaker system for a television set, which is characterized by comprising: a first speaker provided on a front face of the television set, for radiating sound in a forward direction and a second speaker provided with a conical reflector, arranged on a side of the television set and at a position where a sound radiated position is different in height, and depth from the first speaker, for radiating and diffusing the sound to the front of the television set.
According to the first and second inventions, the first speaker radiates forward direction, and the second speaker radiates sound in the side direction which is then reflected in the forward direction.
The second speaker is arranged at the position which is different in height and depth from the first speaker.
Accordingly, in, for example, a case where the same audio signal is input to the first speaker and the second speaker and is heard from the front of the television set, two audios having a time difference from each other enter ears of a user
