    摘要： An acoustic ink print head includes an array of individual emitters. Each of the emitters have a corresponding transducer with a lower electrode (18), a separate layer of a piezo-electric material (16) located on the lower electrode, and a separate upper (14) electrode provided on the upper surface of the piezo-electric layer. The upper and lower electrodes are connected to a source of conventionally modulated RF power. A dielectric layer is deposited on top of this structure and lenses (22) are etched into the top of the dielectric layer. The lenses focus energy generated by the transducer to a region of the upper surface (28) of a body of liquid located above the transducer. The lenses concentrate sound waves from the transducers thereby disturbing the surface and causing droplets (32) to be emitted. The print head is formed as an array of individual emitters. The upper electrodes (14) of the individual emitter array have varying surface areas dependent upon their location within a row of electrodes and their output efficiencies. The upper electrodes are altered in order to provide a uniform end-to-end print output.

    摘要： A driving circuit (106) controls a time for applying a drive signal to a piezoelectric element (101) so as to bring a change in the number of ink droplets squirted from a liquid surface of liquid ink (109) according to a gray scale level of an image to be printed on a printed object. According to application of the drive signal, ultrasonic beams emitted from a piezoelectric element array (101) are converged in an array direction, made incident to an acoustic lens (107) via an acoustic matching layer (105), further converged in a direction orthogonal to the array direction and converged in a vicinity of the liquid surface in a point form. In the vicinity of the liquid surface, an ink meniscus (111) is formed by means of pressure (discharging pressure) generated by the converged ultrasonic beams and then from a tip of the ink meniscus (111) an ink droplet according to the application time is squirted. The squirted ink droplet is flown and stuck to the printed object. By performing main and subscanning to the printed object, a two-dimensional image is printed thereon.
