However, in this case, as shown in FIG. 4, since the acoustic transformer 106 has a tapered shape, a large space is required for a portion where the speaker is to be mounted. .

[0004] Further, Japanese Patent Application No. 9-009535 filed by the applicant of the present invention describes a mounting structure of a speaker in a video display device. As shown in FIGS. 5 and 6, this is because a round-shaped speaker 204 is mounted on a corner 203 extending between the front and side of a front cabinet 202 of a video display device 201 such as a televideo. A duct 210 for sound emission is formed in the corner portion 203 from the front to the side, and a holder 211 to which the round speaker 204 is mounted is fitted into a mounting guide portion 2009 provided in the corner portion 203. By attaching the holder 211 to the front cabinet 202 obliquely in a plan view, the sound of the speaker 204 is emitted to the front side of the front cabinet 202 through the duct 210.

However, in this case, since the speaker 204 is directly mounted on the planar upper surface of the holder 211, sound emitted from the speaker 204 leaks from a gap generated in a mounting portion, and mainly, There was a problem that bass sounds were hard to hear. Further, as shown in FIG. 5, since the sound emitted from the speaker 204 directly hits the inner surface of the front cabinet 202, there is a problem that the front cabinet 202 vibrates and the sound quality is deteriorated.
