摘要： This application provides an elastomer designing method, an elastomer, an SMA assembly, a lens module, and an electronic device. The SMA assembly includes: a fastener, an elastomer, and shape memory alloy SMA lines. One end of the SMA line is connected to the fastener, and the other end is connected to the elastomer. The elastomer includes an elastomer body and at least one elastomer cantilever. The elastomer cantilever is connected to the elastomer body and extends along an outer edge of the elastomer body, the elastomer cantilever is connected to the fastener at a predetermined position of an extending part, and the at least one elastomer cantilever is axisymmetric or 90° rotationally symmetric. According to the foregoing technical solution, mechanical crosstalk of the elastomer in the SMA assembly can be reduced or eliminated, to improve optical image stabilization performance.
