A vibrating toothbrush is provided with vibration-isolating zones that substantially isolate vibrations in the head and reduce vibrations transmitted to the handle without sacrificing structural integrity around the vibration-isolation zones. Such zones may generally comprise neck material that is reduced in cross-section, thinned, replaced by dampening material, or removed altogether to create transmission-inhibiting voids. The vibration-isolating zones may be further supported by the housing of the vibratory element to maintain the structural integrity around the zones and to thereby alleviating weakness conditions that might subject the toothbrush to fatigue and breakage conditions.一種振動牙刷設有數個振動隔離區,彼等大體隔離頭部中的振動且減少傳遞至握把的振動而不犧牲該等振動隔離區四周的結構完整性。該等區域大體由橫截面減少、減薄、用阻尼材料取代、或完全移除以產生數個抑制傳遞之空穴的頸部材料構成。進一步用該振動元件之殼體支撐該等區域以保持該等區域四周的結構完整性且從而減少易使牙刷出現疲勞及斷裂狀態等弱點的狀態。
