Controllable automobile horn system and working method thereof

Abstract

The invention provides a controllable automobile horn system and a working method thereof. The system comprises a camera, a man-machine interaction display module, a central control module and an automobile horn module; the camera collects a real-time road condition and displays the condition on the man-machine interaction display module, and a user delimits a target area on the man-machine interaction display module and designates prompt voice; the central control module generates control information and modulates the prompt voice into an audio transmission signal according to the target area; the automobile horn module converts the audio transmission signal with specific sound volume into ultrasound through an ultrasonic transducer and transmits the ultrasound into air through a narrow wave beam mode, through a strong nonlinear interaction effect of the air, the prompt voice is modulated, pedestrians or vehicles in the designated direction hear the voice, and pedestrians or vehiclesin the other directions cannot hear the voice. According to the controllable automobile horn system, the direction of the prompt voice given out by an automobile horn can be controlled, and noise interference of unrelated people in the other directions is reduced; the sound volume can be adjusted through multi-interaction; the prompt voice is diverse in kind and can be traditional horn prompt voice or multiple kinds of personalized prompt voice.

Description

technical field [0001] The invention relates to the technical field of car horns, in particular to a car horn system with controllable direction, adjustable volume and optional types of prompt sounds and its working method. Background technique [0002] The car horn is the most direct warning tool for pedestrians and other vehicles during driving. The general design of the car horn is as follows: a contact control switch is installed under the decorative film of the steering wheel. When the pressure on the switch reaches a certain level, the car horn is in working condition. At present, car horns are divided into two types according to sound power: electric horns and air horns. The electric horn makes the sound by vibrating the metal diaphragm through continuous power on and off, while the air horn makes the metal diaphragm vibrate and make sound through the compression of the air flow. [0003] At present, these two kinds of car horns have common characteristics: one is t...
