摘要： The invention relates to a leaf spring for an electromagnetic actuator and to such an electromagnetic actuator. The leaf spring is formed as a whole from a disc of plate-shaped, resilient material. The leaf spring comprises a central fastening part, an outer fastening part extending therearound and at least two leaf spring arms extending between the central and outer fastening part. Viewed from the central fastening part, the leaf spring arms (23) have a first zone (24) originating from the central fastening part (21), in which they extend as far as the outer part (22) but for a first clearance (R). The first zone (24) is followed by a second zone (25) in which, without contacting the outer fastening part (22) and proceeding in tangential direction, they bend back as far as the central fastening part (21) but for a second clearance (T). A third zone (26) follows the second zone (25), in which the spring leaf arms (23) extend towards the outer fastening part (22) to merge therein.

摘要： Anti noise system and method, in particular for suppressing sound radiated from a structure, using a formulation of the most efficiently radiating vibration patterns of a vibrating body, the radiation modes, in the time domain. The radiation modes can be used to arrive at efficient weighting schemes for an array of sensors in order to reduce controller dimensionality. The particular radiation modes are determined on the basis of broadband signals. A method is given to obtain these modes from measurable signals on nearfield sensors and microphones in the farfield. The broadband radiation modes are used for the design of an actuator array in a feedback control system to reduce sound power radiated from an object. Three different methods for the design of the actuator are compared, taking into account the reduction of radiated sound power in the controlled frequency range, but also a possible increase of radiated sound power in an uncontrolled frequency range.
