The invention discloses a seat headrest structure for active noise reduction and road noise reduction, and relates to the technical field of active noise reduction devices.The seat headrest structure comprises a headrest, and headset assemblies are installed at the two ends of the headrest surface of the headrest respectively; the headset assembly comprises two storage parts, and a noise reduction assembly, a loudspeaker, a sound guide ring and concentration cotton are sequentially mounted in each storage part; the noise reduction assembly comprises a collecting part used for collecting noise and a counteracting part used for counteracting noise audio. The collection part comprises a sound collection net and a collection microphone assembly used for collecting road noise. And the sound collection net is externally fixed at one end outside the storage part. By means of the annular noise reduction loudspeaker and the loudspeaker, most of sound waves in offset sound waves are guided to the external ear cartilage of the human body by means of the externally-installed sound guide ring, the offset sound waves are transmitted to the auditory ossicle through bone conduction, and therefore the influence of power amplification sound waves in an automobile body on the human body in the running process of the automobile is reduced.
本发明公开了一种用于主动降噪‑路噪的座椅头枕结构,涉及主动降噪装置技术领域,包括头枕,头枕靠枕面的两端分别安装有耳麦组件;所述耳麦组件包括两个存放部件,存放部件的内部依次安装有降噪组件、扩音器、导音环和集中棉;所述降噪组件包括用于收集噪音的收集部件和用于抵消噪音音频的抵消部件;所述收集部件包括集音网和用于收集路噪的收集麦克风组件;集音网外置固定在所述存放部件外部的一端。本发明通过环形降噪扬声器借助扩音器,将抵消声波中的大部分声波借助外置安装的导音环导到人体的外耳软骨处,并在骨传导的传送将抵消声波传动到听小骨处,从而降低汽车在行驶过程中,车身内部功放声波对人体影响。
