Abstract
A 1D ultrasonic converter unit having at least three ultrasonic converters and a control unit for individually controlling each ultrasonic converter, wherein each ultrasonic converter has a housing, a piezoelectric body, and a sound decoupling layer for decoupling sound waves in a gaseous medium, is embedded in a common carrier structure, and emits and/or receives the same frequency between 20 kHz and 400 kHz. Each ultrasonic converter has one sound channel having an input opening associated with one sound decoupling layer, and an output opening. The output openings are arranged along a line, a distance between two adjacent output openings corresponds at most to the whole or half the wavelength of the sound frequency and is smaller than the distance of the input openings.
