Problems solved by technology

There are many factors that lead to car safety. Among them, when the vehicle is driving with the windows closed, the noise in the cab plus environmental noise such as road noise and wind noise outside the car make it very likely that the driver will not be able to hear other vehicles. The sound of the horn cannot be correctly judged and handled, causing unsafe factors and even serious traffic accidents

Embodiment Construction

[0011] The present invention is made up of pickup 1, signal processor 2 and loudspeaker 3 three parts, and its positional relationship is as shown in accompanying drawing 1. Install a pickup 1 respectively on the four corners of the car shell, and then install a signal processor 2 and a loudspeaker 3 at any position in the car. Wherein the signal processor and the loudspeaker are placed together in a box. When the car is driving, when other vehicles sound their horns, the sound will be transmitted to the signal processor by the pickup, and the signal will be amplified by the amplifier circuit first, then the analog signal will be converted into a digital signal by the ADC, and then passed through the band-pass filter Filter out other noises except the speaker sound signal, then convert the digital signal into an analog signal through the DAC, amplify its power through the amplifier, and finally play the filtered speaker sound through the speaker.
