specific Embodiment approach 1
[0016] Specific implementation mode 1. Combination Figure 1 to Figure 3 Describe this embodiment, the chip-type longitudinal vibration composite single-leg piezoelectric ultrasonic motor vibrator described in this embodiment includes a metal base 1 and six piezoelectric ceramic sheets 2,
[0017] The metal base 1 includes two horizontal beams 1-1, a vertical beam 1-2, a driving foot 1-3, two thin-walled beams 1-4 and two flanges 1-5,
[0018] The end of the horizontal beam 1-1 is provided with a horizontal horn 1-1-1, the end of the vertical beam 1-2 is provided with a vertical horn 1-2-1, the horizontal horn 1-1-1 and The vertical horns 1-2-1 are all blocks with gradually tapered cross-sections, and the driving feet 1-3 and the two horizontal horns 1-1-1 and the vertical horn 1-2-1 are small The ends are fixedly connected, two horizontal beams 1-1 and vertical beams 1-2 are set according to T shape, a thin-walled beam 1-4 is set on the side of the two horizontal beams 1-1, ...
specific Embodiment approach 2
[0020] Embodiment 2. The difference between this embodiment and the patch-type longitudinal vibration composite single-foot piezoelectric ultrasonic motor vibrator described in Embodiment 1 is that the two horizontal beams 1-1 and the vertical beam 1- 2. The metal matrix 1 composed of the driving foot 1-3, two thin-walled beams 1-4 and two flanges 1-5 is one piece.
[0021] In this embodiment, the metal matrix 1 composed of two horizontal beams 1-1, a vertical beam 1-2, a driving foot 1-3, two thin-walled beams 1-4 and two flanges 1-5 is one piece, This can greatly simplify the manufacturing process of the ultrasonic motor vibrator; the thin-walled beams 1-4 are used to achieve the effects of elastic support and vibration isolation, and can minimize the influence of the connection between the vibrator and other components on the vibration of the vibrator itself.
