Abstract (en)
[origin: EP0045462A2] In resonant and/or vibrating bodies for sound generators, such as stringed and wind musical instruments, and in loudspeakers, there is the problem of achieving with a small outlay a rich fullness of sound and, in particular, a wide resonance spectrum that is well expressed in the relevant range of audibility. Elongated extension elements (V1, V1a, V1b, V2, V22, V1s, V2s; Vb) having a small cross-section, in particular also in a parallel arrangement and having a common base element (VF), as well as having a large ratio of longitudinal bending strength to mass, effect, when in shear-proof connection with a two-dimensional or bar-shaped resonant and/or vibrating body (RB), with respect to the standing vibrations in the longitudinal direction of the extension elements a predominant stiffening or emphasis of higher frequencies, and with respect to the vibrations in the transverse direction of the extension elements a predominant, additional emphasis of lower frequencies. The application also covers, in particular, sounding boards of mechanised stringed or plucked instruments having bridge-shaped extension elements.
