Example Embodiment
[0031] The present invention will be further described below in conjunction with the drawings and embodiments.
[0032] Such as figure 1 As shown, in the present invention, two pairs of interdigital transducers 2 are lithographically engraved on a square piezoelectric base plate 1, and each pair of interdigital transducers 2 are arranged symmetrically with the central axis of the square piezoelectric base plate 1. A square glass bath 3 is placed in the middle of the piezoelectric base plate 1 and cemented with the piezoelectric base plate 1, and the formed liquid material 4 is placed in the glass bath 3.
[0033] The square glass liquid tank 3 is a bottomless glass liquid tank, and the thickness of the molded liquid material 4 contained in the glass liquid tank 3 is less than or equal to 5 mm by cementing the glass wall surface with the square piezoelectric substrate 1.
[0034] The side length of the square glass bath 3 is less than or equal to the aperture of the interdigital trans...
