Abstract
An anti-resonant structure for speakers includes a resonant structure which has a housing compartment, at least one elastic element located in the housing compartment that has one end fastening to the resonant structure and another end coupling with a speaker, and at least one buffer element located between the resonant structure and the elastic element to serve as a buffer interface to prevent the speaker from hitting due to elastic element and the resonant structure. The speaker is the element that generates vibration. The elastic element has an elastic section to absorb the vibration energy generated by the speaker to prevent the resonant structure from generating unwanted resonance and noises, and prevent electronic elements from being damaged by the resonant effect.
