Lattice structures have attracted significant scholarly attention due to their exceptional mechanical properties, including lightweight characteristics and high strength. Their multifunctionality, such as energy absorption vibration reduction, adds versatility. While extensive research has been conducted on the reduction performance of plate‐type, shell‐type, truss‐type lattice structures, studies cylindrical are comparatively limited. To achieve broadband suppression in this study proposes a novel structure based pyramid cells. The bandgap formation mechanism skeleton examined, with quantitative analysis influence structural parameters using normalized indicators. Results indicate that demonstrates multiple bandgaps within 0–1500 Hz range, exhibiting substantial attenuation capabilities. Additionally, adjusting enables shift toward lower frequencies. Finally, experimental verification finite element model performed by comparing transmission curves maximum relative error −7.48% at resonance peak. This work offers valuable insights for application noise control fields.
