Environment-friendly vehicle orientation loudspeaker system

Abstract

The invention discloses an environment-friendly vehicle orientation loudspeaker system. The environment-friendly vehicle orientation loudspeaker system mainly comprises a dedicated short range communication (DSRC) module, a data processing controller, an ultrasonic testing orientation loudspeaker module, a loudspeaker, a control key 1, a control key 2 and a power source, wherein the data processing controller leads out data lines to be connected with the DSRC module, the ultrasonic testing orientation loudspeaker module, the control key 1, the control key 2 and the power source respectively, the loudspeaker is connected with an output interface of the data processing controller, the DSRC module comprises a microwave transceiver antenna, a modem and a coder decoder, the ultrasonic testing orientation loudspeaker module comprises 16 ultrasonic detectors and 16 orientation loudspeakers, and the data processing controller is an advanced RISC machines (ARM) processor. By means of the environment-friendly vehicle orientation loudspeaker system, noise interference that is brought to other pedestrians around can be avoided to the maximum degree, and living environments of people can be further improved.

Description

technical field [0001] The invention relates to a low-noise vehicle communication device, in particular to an environment-friendly directional horn system for vehicles between vehicles and between vehicles and pedestrians. Background technique [0002] With the advent of the automobile age, harsh car horns sound one after another in the traffic flow, and illegal honking of vehicles has become a major chronic disease in modern cities, especially for residents living on the side of the road. At present, people generally use the traditional car electric horn. The horn is continuously energized and de-energized through the electromagnetic coil to make the metal diaphragm vibrate and produce sound. However, the sound propagation of this horn is divergent and has no directionality, so , It will definitely bring noise disturbance to people around the vehicle or even nearby residents. Contents of the invention [0003] The technical problem solved by the present invention is to p...
