摘要： A material for improving the sound pressure level at the bass reproduction limit of the present invention is composed of an activated carbon having a cumulative pore volume of 0.4 ml/g or more for the pores each having a radius of 50 angstroms or less. Preferably, this activated carbon has a cumulative pore volume of 0.1 ml/g or less for the pores each having a radius of 7 angstroms or less. In particular, when a sound pressure level improving material in which the activated carbon has a cumulative pore volume of 0.5 ml/g or more for the pores each having a radius of 18 angstroms or less is installed in a cabinet of a loudspeaker device, the material alleviates pressure fluctuations of a gas within the cabinet caused by vibration of a loudspeaker, and thus a very good bass reproduction effect is attained. Moreover, in the case where a sound pressure level improving material in which the activated carbon has a cumulative pore volume of 0.4 ml/g or more for the pores each having a radius of 18 to 50 angstroms is installed in the cabinet, a loudspeaker device having a good bass reproduction effect even in an atmosphere of high humidity is obtained.
摘要翻译：用于改善本发明的低音繁殖极限处的声压级的材料由具有50埃半径的孔的累积孔体积为0.4ml / g以上的活性炭构成。优选地，对于每个半径为7埃或更小的孔，该活性炭的累积孔体积为0.1ml / g以下。特别是，在扬声器装置的机壳中安装有对于半径为18埃以下的孔的活性炭的累积孔体积为0.5ml / g以上的声压级改善材料时，材料减轻由扬声器的振动引起的机柜内的气体的压力波动，从而获得非常好的低音再现效果。此外，在机壳中安装有对于半径为18〜50埃的孔的活性炭的累积孔体积为0.4ml / g以上的声压级改善材料的情况下，扬声器装置即使在高湿度的气氛中也能获得良好的低音再现效果。

摘要： In a speaker system capable of controlling the directivity, a first pair of speaker units are disposed at a cabinet from face having vertical and horizontal axes, so that the diaphragm centers are located along a line which is parallel with the horizontal axis of the front face. A second pair of speaker units are disposed so that the diaphragm centers are located along a line which is parallel with the vertical axis of the front face. The horizontal distance between the centers of the diaphragms of the first pair of speaker units and the vertical distance between the centers of the second pair of speaker units are different from each other. The center of the line which links the diaphragm centers of the first pair of speaker units and the center of the line which links the diaphragm centers of the second pair of speaker units are located at the same position. A fifth speaker unit may be disposed on the front face of the cabinet at a center of an area surrounded by the first and second pair of speaker units.

摘要： A magnetic circuit for a loudspeaker includes a magnet and a top plate. The magnet is made of a bonded magnet. The magnet and the top plate are configured to satisfy at least one of conditions that an inner diameter of the magnet is identical to an inner diameter of the top plate, and that an outer diameter of the magnet is identical to an outer diameter of the top plate. This configuration eliminates a wasted space inside the magnetic circuit, and protrusion of the magnet to outside, hence providing a light and efficient magnetic circuit.

摘要： A loudspeaker includes a diaphragm, an edge, and a voice coil. The diaphragm includes a groove having a concave cross section. Also, the diaphragm is in a horizontally or vertically elongated shape. The edge is coupled to an outer circumference of the diaphragm, and has a roughly half-round shaped cross section. The voice coil is bonded to the groove. The voice coil is thicker than a depth of the groove. Also, the voice coil has a cross section in which a dimension in a direction along a plane of the diaphragm is longer than a dimension in a direction perpendicular to the plane of the diaphragm.
