SPEAKER APPARATUS AND TELEVISION SET

摘要

A FIRST FEATURE OF THE PRESENT INVENTION IS THAT THE OPENING OF A SOUND INPUT PORT (3B) IS SMALLER IN AREA THAT THE OPENING OF A SOUND INPUT PORT (3A) IN A HORN (3). A SECOND FEATURE IS THAT THE SOUND OUTPUT PORT (3B) OF THE HORN (3) IS LOCATED SO AS NOT TO BE IN THE WAY OF A CENTER AXIS OF SOUND RADIATION FROM A SPEAKER (2). A THIRD FEATURE IS THAT A LENGTH (L) OF THE HORN (3) IS SET AT 370 MM OR BELOW. A FOURTH FEATURE IS THAT THE HORN (3) IS GRADUALLY NARROWED SUCH THAT VERTICAL SECTIONS THEREOF FROM THE SOUND INPUT PORT (3A) TO THE SOUND OUTPUT PORT (3B) RESPECTIVELY HAVE AREAS BASED ON A PREDETERMINED ROLE. THUS, IT IS POSSIBLE TO REALIZE A SPEAKER APPARATUS IN WHICH A SOUND OUTPUT PORT OF A HORN IS SMALLER IN AREA THAN A VIBRATING SURFACE OF A SPEAKER VOLUME WHILE REPRODUCING SOUND WHOSE QUALITY IS EQUAL OR SIMILAR TO THAT IN CONVENTIONAL SPEAKER APPARATUS, AND A TELEVISION SET EQUIPPED WITH THE SPEAKER APPARATUS.FIGURE 1
