A vibration-reducing structure for compressing diaphragm pump features a pump head body and a diaphragm membrane. The pump head body includes four operating holes, a first curved vibration-reducing positioning structure circumferentially disposed around the upper side of each operating hole, and or a linked four-curve positioning structure that collectively extends around all of the operating holes. The diaphragm membrane includes four equivalent piston acting zones and second curved vibration-reducing position structures situated at positions corresponding to the positions of the first curved vibration-reducing positioning structures. The first positioning structures in the pump head body, which may be grooves, slots, perforations, or protrusions, mate with the corresponding second positioning structures in the diaphragm membrane to reduce the moment arm generated during pumping by movement of the diaphragm membrane, which may be protrusions, grooves, slots, or perforations, thereby generating less torque to decrease the strength of vibrations and vibration noise. |
