A rearview mirror having an auxiliary function is composed of a rearview mirror body, a back-up lens and a paraboloid transmitting piece. The back-up lens is arranged in an opening in the rearview mirror body; an inner frame is arranged outside the back-up lens; positioning holes are formed in the upper and lower parts of the inner frame; a positioning shaft is arranged on the paraboloid transmitting piece and arranged in the positioning holes. The overall thickness of the paraboloid transmitting piece is consistent, the light transmittance of the paraboloid transmitting piece is greater than 7%, audio signals in the rear can be reflected and gathered into a focal point by the paraboloid transmitting piece, the distance between the focus and the paraboloid transmitting piece is within 700mm-1100mm, and the paraboloid transmitting piece is made of a hard material having high acoustic wave reflection performances. The inner diameters of the positioning holes formed in the inner frame and the outer diameter of the paraboloid transmitting piece are the same. By applying the rearview mirror, the audio signals transmitted from the rear can be reflected and gathered to the ears of a driver, so that the driver also can hear the overtaking signal from rear vehicles even under the condition that window glass is closed.
