    摘要： A sound field offset device having two channels, each of which includes a frequency selection filter for dividing a stereophonic input signal into two frequency bands by a given frequency falling within an audio frequency, at least one digital filter for performing sound field offsetting within a lower frequency band, and at least one loudspeaker assembly for a higher frequency band having a sharp directivity pattern and capable of defining an area to which acoustic power is emitted. This device allows a sound field to be offset in a cost effective and simple manner, by improving the frequency characteristic of a sound field space and by clarifying the sense of locality of acoustic images.

    摘要： A speaker and the like, which is capable of wideband reproduction by improving the bass characteristic, and which is suitable for size reduction, is provided.A housing (110) includes one main surface (111) having a polygonal shape, and an opening portion (112) in the one main surface. A diaphragm (120) is disposed in the opening portion so as to cover the one main surface, except for corner regions (115a, 115b, 115c, and 115d) which are areas in the vicinity of respective vertices of a polygonal shape of the one main surface. A driving unit (130) causes the diaphragm to vibrate so as to generate a sound corresponding to a signal inputted from an outside. A plurality of movable supports (140a, 140b, 140c, and 140d) is disposed in the respective corner regions, for supporting the diaphragm by joining the housing and the diaphragm such that the diaphragm is vibratable.

    摘要： A speaker system according to the present invention comprises a cabinet (10), a speaker unit (11), a first parting board (12), a drone cone (13), an adsorption member (14), a second parting board (15), a backboard (16), a variable mechanism (17), and a port (18). A sound pressure generated by the speaker unit (11) causes a pressure variation in a second chamber (R12) via the drone cone (13). The adsorption member (14) with an effect of physical adsorption is operable to suppress the pressure variation. Furthermore, by displacing the diaphragm (171), the variable mechanism (17) is operable to reduce a pressure variation of a direct current component, which is caused by variations in ambient temperature or atmospheric pressure of the speaker system.
