VIBRATION TYPE DRIVING APPARATUS, INTERCHANGEABLE LENS AND IMAGING APPARATUS INCLUDING VIBRATION TYPE DRIVING APPARATUS, AND METHOD FOR ADJUSTING VIBRATION TYPE DRIVING APPARATUS

摘要

A vibration type driving apparatus includes a first vibrator including an electro-mechanical energy conversion element and configured to be in pressure contact with a driven member, a second vibrator including an electro-mechanical energy conversion element and configured to be in pressure contact with the driven member, and a first electric element connected in series with the second vibrator. The first vibrator is connected to a driving circuit, the second vibrator and the first electric element are connected in parallel with the first vibrator, the second vibrator is connected to the driving circuit via the first electric element, and a resonance frequency f1 of the first vibrator and a resonance frequency f2 of the second vibrator satisfy a relationship f1 f2.
