Abstract: A vibration device includes a light transmissive body, a first cylindrical body, a plate-shaped spring portion, a second cylindrical body, and a vibrating body. The light transmissive body includes a main body portion on an inner side of a portion supported by the first cylindrical body, and a protruding portion extending from the main body portion toward an outer circumference of the light transmissive body and protruding outward more than a portion supported by the first cylindrical body. A ratio between an equivalent mass calculated from a moment of inertia of the protruding portion and a weight of the main body portion is about 0.8 to about 1.2, and a resonant frequency of the light transmissive body is larger than a resonant frequency of the spring portion.

Abstract: An ultrasonic nebulizer including a circuit unit, a nebulization module, and a frequency sweeping unit. Constant electric power in the nebulization module of the ultrasonic nebulizer is maintained by automatic compensation of electric power consumption and/or current consumption. A fixed current consumption and electric power consumption of the nebulization module of the ultrasonic nebulizer is achieved by auto compensation, thereby improving nebulization performance.

Abstract: A generator for exciting a piezoelectric transducer, includes at least one digital processor unit. The digital processor unit is configured to operate at least in an iterative operation stage including more than two successive iterations. Each iteration includes: exciting the transducer at a plurality of frequencies in a frequency band about a set-point frequency; during transducer excitation, acquiring one or more values related to at least one electrical magnitude associated with the excitation of the transducer for a plurality of frequencies in the frequency band; and analyzing the values acquired to determine a new set-point frequency for a subsequent iteration.

Abstract: Noise potentials and radiation in an ultrasonic nebulizer are reduced by separating the oscillator and power supply and shielding the former, with one of the DC power lines to the oscillator passing through an aperture in the metal casing that shields the oscillator, while the other power supply line is connected to that casing. Oscillator control may be achieved by an unshielded variable resistor coupled by conductors of extended length to the oscillator by a filter circuit.
