Abstract: PURPOSE: A sound reproducing apparatus is provided to provide an optimal acoustic environment suitable for a user by reproducing sound having desired spatial characteristics in a listening area. CONSTITUTION: A control means reproduces sound at a specific location in a listening area by receiving first and second sound source signals. The control means outputs the first and second sound source signals by controlling the size and phase of the first and the second source signals. A first speaker reproduces sound by receiving a first control sound source signal. A second speaker reproduces the sound by receiving a second control sound source signal. An input means displays a specific location in the listening area and the location of a listener. The input means is formed into a touch panel.

Abstract: PURPOSE: A sound reproducing device is provided to grasp a transfer function considering features of a sound space, thereby enabling a user to obtain a sound signal optimized for generating a listening area. CONSTITUTION: The higher a sound pressure level of a listening area is than other areas except for the listening area, the more first, second, and third control sound signals a control unit outputs by controlling the amplitudes and phases of the first, second, and third sound signals. A first speaker(111) reproduces a sound by receiving the first control sound signal. A second speaker(112) reproduces a sound by receiving the second control sound signal. A third speaker(113) reproduces a sound by receiving the third control sound signal.

Abstract: PURPOSE: A sound reproducing device is provided to offer an optimal acoustic environment suitable for a user by controlling the size and phase of a first and a second sound source signals to maximize the ratio of the acoustic potential energy density at a specific location in a listening space to the energy sum of the first and second sound source signal, thereby reproducing sounds having desired spatial characteristics in the listening space. CONSTITUTION: A first and a second speaker playing the role of a sound source are installed in a listening space(a). The listening space is where a listener is located, and a location(b) of the listener is where the listener is currently located in the listening space. The location of an acoustic concentration point(c) is away from the location of the listener, and the number of the acoustic concentration point is one or more than one. A user is able to change the location of the acoustic concentration point by moving the acoustic concentration point on an input unit. A control unit determines a sound source signal maximizing the ratio of the acoustic potential energy density at the acoustic concentration point to the sum of individual sound source signal energy, and enables a sound to be heard as if sounds different from each other are reproduced at two or more specific locations.

Abstract: PURPOSE: A sound reproducing apparatus is provided to control the size and phase of a first and a second sound resource signal to make a sound pressure level in a specific location within a listening space is higher than the sound pressure level in other location, thereby providing an optimal acoustic environment fitting for a user by playing the acoustic having a desired spatial property within the listening space. CONSTITUTION: In a listening space(a), a first and a second speaker serving as a sound resource are installed. The listening space is a location a listener wants, and a listener location(b) is a location in which the listener is currently located in the listening space. The location of an acoustic concentration point(c) is apart from the listener location, and the number is able to be one or more than two. A user is able to change the location of the acoustic concentration point by moving the acoustic concentration point in an input device. A control device decides a sound resource signal which makes a sound pressure level in the acoustic concentration point higher than the sound pressure level in other areas, so that the sound is heard as the different acoustic is played in more than two specific locations.
