VIBRATION-TYPE MOTOR, LENS DEVICE AND ELECTRONIC DEVICE Russian patent published in 2019 - IPC H02N2/12 G02B7/04 G02B7/08 H01L41/09 

Abstract RU 2704630 C1

FIELD: electrical engineering.

SUBSTANCE: invention relates to the electrical equipment. Vibration-type motor includes first and second vibrators, a friction element configured to touch first and second vibrators, clamping element configured to press the first and second vibrators to the friction element, and the first and second guide elements configured to direct the relative movement between the first and second vibrators and the friction element. First and second dipoles are spaced apart in a direction different from the direction of relative displacement between the first and second vibrators and the friction element. First guide element and the second guide element are provided between the first vibrator and the second vibrator in a direction different from the direction of relative displacement. Pressure center for pressure applied to first vibrator and second vibrator by clamping element is located between first guide element and second guide element.

EFFECT: reduction in overall dimensions.
