In the structural design of electronic equipment, the partial enhancement is usually used to increase local stiffness and decrease acceleration response. But sometimes, this measure does not work well. To reduce the acceleration response of key components in a structural, in this paper, the structure has been optimized by the octave rule, Reduce the response of core components by reasonably weakening the stiffness of the bracket. As a result, the acceleration responses of the resonator have been reduced by 29% under the condition of weakening some structural components. In this paper, the response of the core component is reduced by weakening the non-core component, which is different from the conventional increase in the overall structural stiffness to reduce the response, which is of some guiding significance to the optimization design of electronic equipment.
