摘要： A compressor includes a cylinder block having a compression chamber therein, a piston arranged in the compression chamber which reciprocates up and down, and a driving mechanism which drives the piston. The driving mechanism includes an elastic member whose peripheral portions are fixed to the cylinder block so as to allow the elastic member to oscillate up and down, and whose center portion is attached to the piston, and one or more piezoelectric actuators that are arranged on the elastic member. In response to a power, one or more piezoelectric actuators repeatedly deform and apply an exciting power to the elastic member.

摘要： A noise control apparatus for a vacuum cleaner, having a simple construction and capable of easy installation in the vacuum cleaner which effectively attenuates noise in a wide frequency band. The noise control apparatus includes a control unit, a noise detecting unit for detecting a noise generated from a noise source, generating a noise level signal on the basis of the noise detection, and sending the noise level signal to the control unit, a control sound generating unit for generating a control sound adapted to attenuate the noise from the noise source under a control of the control unit, and an error sound detecting unit for detecting an error sound resulting from the noise attenuation by the control sound from the control sound generating unit, generating an error sound signal on the basis of the error sound detection, and sending the error sound signal to the control unit. A low pass filter is coupled to each of the noise detecting units, the error sound detecting unit and the control sound generating unit. By the provision of such a low pass filter, it is possible to greatly attenuate noise having a frequency of 500 Hz or below.
