Abstract: A loudspeaker device includes: a first loudspeaker that outputs a sound; a second loudspeaker that is adjacent to the first loudspeaker in a predetermined direction and outputs a sound in a direction intersecting with a direction in which the first loudspeaker outputs the sound; and a phase switching circuit that switches between a first switching state and a second switching state, the first switching state being a state in which an input sound signal is inputted to both the first loudspeaker and the second loudspeaker, the second switching state being a state in which the input sound signal is inputted to one of the first loudspeaker and the second loudspeaker while an inverted sound signal obtained by inverting a phase of the input sound signal is inputted to the other of the first loudspeaker and the second loudspeaker.

Abstract: A sound reproduction method is provided. The method includes acquiring ambient sound information that includes voice spoken to a speech dialog system and indicates sound around a speaking person who has spoken the voice. The method also includes separating the ambient sound information into first sound information including the spoken voice and second sound information including sound other than the spoken voice. The method further includes comparing the sound level of the first sound information with the sound level of the second sound information, and reproducing an audio response to the spoken voice, by selecting one of a first reproduction method and a second reproduction method that is different in terms of directivity of reproduced sound from the first reproduction method in accordance with a result of the comparison.

Abstract: There is provided a method for creating machining data for a hybrid ultraprecision machining device for manufacturing a micro-machined product from a workpiece, the machining device comprising: an electromagnetic-wave-machining means for roughly machining the workpiece; a precision-machining means for precisely machining the roughly machined workpiece; and a shape-measurement means, wherein the creation of the machining data makes use of: information on original shape corresponding to shape of the workpiece; information on roughly-machining shape to be removed from the workpiece by the electromagnetic-wave-machining means; and stereoscopic model of after-electromagnetic-wave-machining shape which is obtained by subtracting the roughly-machining shape from the original shape, wherein the machining data is created for electromagnetic-wave machining on the basis of information on a plurality of sliced portions obtained by partially slice-cutting from the stereoscopic model of the after-electromagnetic-wave-machining shape.

Abstract: A loudspeaker includes: a frame; a yoke fixed to the frame; a magnet fixed to the yoke; a plate fixed to an upper surface of the magnet which is opposite to a surface of the magnet which is fixed to the yoke; a vibratable voice coil arranged in a first magnetic gap formed between the yoke and the plate; a diaphragm having an outer-edge portion joined to the voice coil; and a support member supporting the diaphragm in a vibratable manner, and composed of edges, one end of each edge being fixed to the frame. The plate is composed of: a flat-plate part fixed to the upper surface of the magnet, and having, at an upper surface thereof, a planar portion extending from the outer-edge portion up to a predetermined distance; and a protruding part disposed on the flat-plate part excluding the planar portion, and protruding toward the diaphragm.
