<P>PROBLEM TO BE SOLVED: To provide a loudspeaker apparatus for suppressing attenuation of high pass sound and the occurrence of a standing wave, and for enjoying richer sound field expressions according to the kinds of reproduction sounds. <P>SOLUTION: The loudspeaker apparatus includes: a first loudspeaker unit 3a integrally formed by using isotropic materials, and equipped with a first diaphragm 1a having first belt-like reinforcing parts 13a to 13d with Young's modulus which is higher than that of a second region section in a first region section; a second loudspeaker unit 3b integrally formed by using the isotropic materials, and equipped with a second diaphragm 1b having second belt-like reinforcing parts 13a to 13d with Young's modulus which is higher than that of a fourth region section in a third region section; a cabinet 2a in which the first and second loudspeaker units 3a and 3b are arranged so as to be lined up on the front face; and a turning mechanism for turning the first diaphragm 1a in its circumferential direction, and for changing the directions of the first reinforcing parts 13a to 13d. <P>COPYRIGHT: (C)2010,JPO&INPIT |
