Abstract (en)

[origin: WO2011064028A1] The present invention relates to an electric tool (1) having a vibratory means (58) which is provided for imparting a counteracting vibration (103) which counteracts a housing vibration (100) of the electric tool (1), wherein a vibration-relevant characteristic (Wo, 51, Kf, 112-115, 106, 52) of the vibratory means (58) can be adapted during the operation of the electric tool (1) in such a way that the amplitude (104), the phase position and/or the frequency (1/T) of the counteracting vibration (103) varies with a change in the vibration-relevant characteristic. The present invention also relates to an electric tool (1) which is in particular in accordance with the invention and whose vibratory means (58) have a natural frequency which can be varied by variation means of the electric tool (1). The present invention also relates to a method for compensating housing vibrations (100), in particular of the electric tool (1) according to the invention, having a vibratory means (58) which is provided for imparting a counteracting vibration (103) which counteracts a housing vibration (100) of the electric tool (1), wherein the amplitude, the phase position and/or the frequency of the counteracting vibration (103) is varied during the operation of the electric tool (1).
