DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a tube television having a Dolby type A reproduction circuit.

(Prior Art) A conventional tube-shaped television of this type (hereinafter referred to as a television) will be explained with reference to FIGS. 3 and 4.

FIG. 3 is a front view of a tube television using a phantom center speaker as the center channel speaker of a Dolby type A reproduction speaker system. The center channel signal is input to the left and right phantom speakers.

It was configured like this. On Television 1.

The sound sources 4a and 5a of the left and right channel speakers 4 and 5 are located approximately in the center of their respective speaker boxes, and the synthesized sound source 1b of the phantom-shaped center channel speakers 2 and 3 is located approximately in the center of the display surface 1a of the television 1. It sounds like It is desirable that the sound of the center channel be localized on the display surface la, but this is physically impossible, so speakers are installed on the left and right sides.

FIG. 4 is a front view of a tube-type television using a general speaker box as a center channel speaker. The television 1 is installed on two television stands 6 and 7, the left channel speaker 4 and the right channel speaker 5 are placed on the left and right sides, and the center channel speaker 8 is placed below the television 1. Ru.

In the above configuration, the sound source 8 of the center channel speaker 8
A is approximately at the center of the speaker box. In this way, the center channel audio is transmitted to the display surface la.
It is desirable to position it at the top.

Since it is physically impossible, it is installed at the bottom.

(Problems to be Solved by the Invention) However, in the above configuration, when listening at the center of the phantom type center speakers 2 and 3, the following problem occurs.

Although the center channel sound sounds as if it is coming from the synthesized sound source 1b on the display surface 1a, there is a problem in that the sound image becomes unnatural when listened to from a position shifted to the left or right.

In addition, in the case of the center channel speaker 8, since the center channel sound source 8a is located below the display surface 1a, there is a problem in that dialogue etc. cannot be heard from the display surface 1a, making it unnatural.

The present invention solves the above problem and provides a tube-type television in which center channel sound is localized on the display surface 1a.

(Means for Solving the Problems) In order to solve the above problems, the present invention provides a tube-type television set with speakers facing the display screen.

(Function) With the above configuration, when the center channel sound is generated from the speaker, it is reflected on the display surface and creates a false sound source behind the display surface, giving the viewer the impression that the sound is coming from the display surface. do.

(Example) An example of the present invention will be described with reference to FIGS. 1 and 2. 1 and 2 are a side sectional view and a front view of a television according to the present invention.

In FIG. 1, a television 1 has a display surface 1
A center channel speaker 9 facing the display surface 1a is provided on the lower front surface of the display panel a.

Further, as shown in FIG. 2, a left channel speaker 10 and a right channel speaker 11 are arranged on the left and right sides of the display surface 1a.

The operation of the television 1 configured as above will be explained.

The sound 12 generated from the center channel speaker 9 is
The sound is reflected on the display surface 1a, producing a virtual sound source 1c deep within the display surface 1a, and the viewer perceives the sound as if it were coming from the display surface 1a! I feel like I'm emitting 3.

As described above, according to this embodiment, the tube-type television equipped with the Dolby type reproducing circuit and the center channel speaker 9 can make the user feel as if the sound is being emitted from the display surface 1a. In this embodiment, the center channel speaker 9 is a single-way, sealed type, but it goes without saying that a multi-way, bass reflex type, etc. may also be used.

(Effects of the Invention) As explained above, according to the present invention, Dolby system A
In a tube type television equipped with a type reproduction circuit and a center channel speaker, it is relatively easy to feel that the center channel sound is coming from the display surface, and enjoy natural reproduction.
