specific Embodiment approach 1
[0010] Specific implementation mode 1: Combination Figure 1 to Figure 4 To illustrate this embodiment, the U-shaped biped linear ultrasonic motor vibrator in this embodiment includes two connecting end covers 1, twelve piezoelectric ceramic plates 2, a flange 3, four insulating sleeves 4, and twelve pieces The electrode sheet 5 and two independent end caps 6; the connecting end cap 1 includes a vertical horn 1-2, a horizontal horn 1-1 and a driving foot 1-3, a vertical horn 1-2 and The horizontal horns 1-1 are all quadrangular prisms with a rectangular cross-section and tapering. The large end faces of the vertical horns 1-2 and the horizontal horns 1-1 have a blind with internal thread. The driving foot 1-3 is a rectangular parallelepiped, the upper end surface of the driving foot 1-3 is connected with the small end surface of the vertical horn 1-2, and the upper side of the driving foot 1-3 is connected with the horizontal horn 1- 2 is connected with the small end faces, th...
specific Embodiment approach 2
[0012] Embodiment 2: The difference between this embodiment and the U-shaped biped linear ultrasonic motor vibrator described in Embodiment 1 is that the cross-sections of the piezoelectric ceramic sheet 2 and the rear cover 3 are square or circular.
