The present invention relates to a high-efficient aroma-diffusing apparatus wherein a general aroma-diffusing apparatus sprays an aromatic agent stored in an expensive air can by discharging an aromatic agent with a compressed gas inside the can. An aroma-diffusing undiluted solution fused with gas which causes a problem of environmental pollution is transformed into a chemical component and some portion thereof may be applied as a harmful component to a human body. The present invention is an apparatus which can evaporate and spray a naturally extracted aromatic liquid, which is not made of artificial and chemical aromatic components, just like a conventional spray nozzle. To this end, a predetermined amount of an aromatic agent is automatically lifted to a lower end of an oscillator, the oscillator is fixed to a center such that a moisture is positioned to a predetermined interval corresponding to a vibration degree of the oscillator, a spraying vibration stage positions an upper end of a circular guide member in a lower end of the oscillator at regular intervals, a solid guide member automatically lifts the moisture to a center of a lower end of the spraying vibration stage and moves the moisture to the circular guide member, and the solid guide member is fixed to a lead-in pipe and coupled to a container storing a liquid of an aromatic agent such that a liquid component does out leak outside regardless of being shaken or overturned, and enables a predetermined amount to be diffused consistently. The conventional method of spraying aromatic components can be applied in the same manner, and therefore, it is possible to have an environment-friendly aromatic effect and a psychological stability gained from natural extracts at the same time. The present apparatus is capable of satisfying functions such as a light weight-type, a multi-purpose humidity adjustment purpose, and a humidifier by adjusting various spraying cycles, concentration of an aromatic agent, and vol
