ACOUSTIC QUALITY MODIFICATION ELEMENT, AUDIO SYSTEM, AUDIO AMPLIFIER DEVICE EQUIPPED WITH ACOUSTIC QUALITY MODIFICATION ELEMENT, AND SPEAKER SYSTEM EQUIPPED WITH ACOUSTIC QUALITY MODIFICATION ELEMENT

摘要

These acoustic quality modification elements (10A, 10B, 10C, 110, 210, 210A, 210B) are connected to connection channels (70PW, 70NW) extending from audio amplifier circuits (31) for outputting audio signals (SA), to one or more loudspeakers (41), and modify the acoustic qualities of sounds (SD) radiated from the loudspeakers. The acoustic quality modification elements are each provided with an element body (11, 111) comprising: an element block (12, 112) made of a single metal block having a dimension (D) of at least 5 mm in the radial direction (DH) and a dimension (L) of at least 5 mm in the longitudinal direction (LH); and at least a first element terminal (13, 113) disposed at one end (12T1, 112T1) of the element block, and, as an option, a second element terminal (14) disposed at the other end (12T2).
