な設計の中で最適な音響効果を得ることができる。As described above, the audio device of the television receiver of the present invention utilizes the cabinet, the ribs provided on the cabinet, and the CRT as a side wall forming the horn portion, and effectively makes the gap between the cabinet and the CRT effective. By using it, the space of the horn can be widened and the acoustic effect can be improved. Further, by substantially dividing the horn part into two and shortening the length of the horn part on the main body side, the mold structure and molding are simplified, and as a result, the cost of the speaker device main body can be reduced. Further, if the length dimension of the additional horn portion is determined in advance corresponding to the screen size of each television receiver, by changing the thickness of the sponge 4, one type of speaker device can provide a wide range of screen size TVs. It is compatible with John receivers and can always obtain optimum acoustic effects in a compact design.
