Abstract
Disclosed is an application device, comprising a plurality of elastic members, each elastic member comprises a first connecting portion, a second connecting portion and a deformation portion therebetween, the first connecting portion and the second connecting portion are respectively connected to different members in the application device, and the different members are movable or fixed relative to each other, wherein the deformation portion is formed by extending from a first end to a second end in a straight line and/or a curve in the same direction or in different directions. According to the present disclosure, the manufacturing is simple and convenient, thinning of product is facilitated, and the elastic members maintain good compliance, without influencing the vibration of a vibration unit. At least one elastic member is widened and/or has at least two cross sections with different sizes, thereby reducing the stress concentration, and eliminating the resonance.
