Abstract

A multifunctional rearview mirror comprises a rearview mirror body, a rearview mirror and a paraboloid transmitter. The rearview mirror is arranged in an opening of the rearview mirror body, an inner frame is arranged outside the rearview mirror, the upper side and lower side of the inner frame are provided with positioning holes respectively, and a positioning shaft is arranged on the paraboloid transmitter and disposed in the positioning holes. The integral thickness of the paraboloid transmitter is uniform and the transmittance rate thereof is larger than 7%. The paraboloid transmitter can reflect audio signals behind into a focus, the distance between the focus and the paraboloid ranges from 700 mm to 1100 mm, and the paraboloid transmitter is made of hard materials high in sound wave reflection performance. The inner diameter of the positioning holes of the inner frame is same as the outer diameter of the positioning shaft arranged on the paraboloid transmitter. Audio signals behind can be reflected and focused to the ears of a driver, and even in case car windows are closed, the driver can hear overtaking signals transmitted by cars behind.

Description

technical field [0001] The invention relates to a motor vehicle rearview mirror, in particular to a multifunctional rearview mirror. Background technique [0002] When a vehicle is overtaking, if the vehicle in front is blocking the way, it is generally necessary to honk the horn to signal the vehicle in front to give way. While the vehicle is moving, especially when the window is closed, it is often difficult to hear the horn of the vehicle behind, which brings a greater hidden danger to safe driving. There is no device and method for solving this problem at present. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the present invention provides a multifunctional rearview mirror, which uses a lens with an acoustic focusing function installed in front of the rearview mirror to gather the sound from the rear of the vehicle to the driver's ear, making the driver The driver can hear the horn of the vehicle behind. [0004] The purpose of the p...
