Abstract

PROBLEM TO BE SOLVED: To provide a television receiver with which a user can enjoy sound with wide realistic sensations only with built-in speakers of the television receiver. SOLUTION: A first speaker 1 is fixed to the front face of a cabinet 3, a second speaker 2 having a sound guiding pipe 4 extending tiltedly toward a slant side face from the cabinet 3 at the back of the first speaker 1 and having a means for stressing and reproducing sound equal to or greater than 4 kHz at the sound guiding pipe is fixed tiltedly toward the slant side face, and the sound equal to or greater than 4 kHz is stressed and emitted from a sound hole 5a provided on the side face of a back cover 5, that is, emitted slantly from the back of the first speaker 1.

Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a television receiver, a display device, and the like. 2. Description of the Related Art Conventionally, in a speaker system mounted on a television receiver, there is a restriction that the speaker system is mounted in a limited space inside a housing of the television receiver. However, it was very difficult to reproduce the sound field with a spacious and realistic feeling. Recently, for example, Japanese Patent Application Laid-Open
Japanese Patent Application Laid-Open No. 95576/1995 includes a drive device for rotating a speaker box.
It has been proposed to use a reflector and an acoustic lens for controlling the directivity of sound as disclosed in Japanese Patent No. 222180. [0003] However, in the above prior art, it is necessary to provide an expensive driving device, and the viewer is forced to perform a complicated operation of rotating the speaker. Also, the use of a reflector and an acoustic lens for controlling the directivity of sound involves a risk of sound quality degradation even if the sound pressure level is reduced and the frequency characteristics are changed and the directivity is improved. Therefore, there has been a long-felt need for a proposal that has a simple configuration and produces a sound with a sense of realism. [0004] The television receiver of the present invention solves such a conventional problem, and it is possible to enjoy wide and realistic sound with only the built-in speaker of the television receiver. It is to be. [0005] A first speaker is fixed to the front of the front of the cabinet, and a sound pipe extending obliquely from the cabinet to the oblique side is provided behind the first speaker. The sound pipe has a frequency of 4 kHz. A second method having a means for reproducing the above sound with emphasis
The speaker is tilted to the oblique side and fixed, and the sound of 4 kHz or more is emphasized from the sound hole provided on the side of the back cover to radiate obliquely from the rear of the first speaker to form a sound image having a wide spread. A television receiver characterized by being realized. According to the television receiver of the present invention, it is possible to enjoy a wide and realistic sound with the television receiver. An embodiment of the present invention will be described below with reference to FIGS. 1 and 2. FIG. 1 is an overall plan sectional view of the television receiver of the present invention, and FIG. 2 is a detailed plan sectional view of the television receiver of the present invention. 1 and 2, reference numeral 1 denotes a first speed.
2, 2 is a second speaker, 3 is a cabinet, 3a is a cabinet sound hole, 4 is a sound conduit, 4a is a wall of a sound conduit, 5 is a back cover, 5a is a back cover sound hole, and 6 is a CRT. ing. For example, the first speaker 1 is a full-range speaker capable of reproducing from a low band to a high band.
It is fixed to the cabinet 3 below the RT 6. The sound of the first speaker 1 is emitted from a cabinet sound hole 3a provided in the cabinet 3 toward the front of the television receiver. The second speaker 2 is 4k
It is a speaker having a means for reproducing with emphasis of Hz or more, for example, a tweeter. The second speaker 2 is directed to a sound conduit 4 extending obliquely rearward from the first speaker 1 in an oblique side direction with respect to a direction in which the first speaker emits sound. So that it is fixed. The sound conduit 4 is open with no wall on the side surface on the back cover 5 side, and has a wall 4a only on the CRT 6 side. Second
The sound radiated from the speaker is reflected by the wall 4a of the sound conduit 4 and efficiently guided to the sound hole 5a provided on the side surface of the back cover 5. By locating the speaker according to the structure of the present invention, it is possible to reproduce a sound field with a wide and realistic feeling. As described above, according to the television receiver of the present invention, it is possible to reproduce a sound field with a wide and realistic feeling.
