PURPOSE:To obtain a speaker system improving the sound sensitivity of a speaker by providing a diaphragm directed nearly horizontally and a diaphragm directed nearly vertically to one box. CONSTITUTION:The diaphragm 2 in the horizontal direction and the diaphragm 30 in the vertical direction are provided to the box 14. The speaker of the diaphragm 2 acts as a woofer and irradiates upward the sound from 5 to 7,000Hz and the diaphragm 30 irradiates three-dimensionally the sound of 6,000-40,000 Hz in forward direction so as to enclose a human body 18. Thus, one speaker sytem is used for a stereo equipment and a super-woofer in common, the small sized system offers the sound quality of a large sized system, the sound of broad band is obtained and the speaker equipment with less input, high efficiency and low cost is obtained. |
