摘要： An inertial vibration exciter having a magnet assembly defining an annular gap, a coil assembly disposed in the annular gap, suspension means mounting the coil assembly for reciprocating movement in the gap, means coupling the coil assembly to a member to be vibrated, and a hermetically sealed housing in which the magnet assembly, the coil assembly, the suspension means and the coupling means are disposed. The housing may comprise a heat sink thermally coupled to the magnet assembly and the heat sink may be resiliently coupled to the housing. The coupling means may comprise a plate-like member to which the coil is rigidly attached and of a size substantially greater than the diameter of the coil. The plate-like member may be resiliently coupled to the housing. Mounting means such as a pressure-sensitive adhesive member may be positioned centrally on the plate-like coupling means and adapted to mount the inertial vibration exciter to the member to be vibrated, the mounting means being of a substantially smaller size than the coupling means to leave the periphery of the coupling means free to move.

摘要： A switching amplifier includes a modulator, which includes a pulse generator. The pulse generator generates positive and negative pulses, in response to an input signal, and the frequency of the negative pulses can be controlled independently of the frequency of the positive pulses. The positive pulses and negative pulses are combined to form a composite pulse stream, which can be low-pass filtered such that the filter output is an amplified version of the input signal.
