Embodiment Construction

[0010] Below in conjunction with accompanying drawing, the implementation of the present invention is described as follows:

[0011] As shown in Figure 1, a set of bass auxiliary sound system is installed on the car, which consists of sound facilities, connecting wires, and a control switch system installed in the cab. The connecting wire connects the control switch system in the cab with the sounding facilities on the car outside the cab. In this way, when the control switch is turned on in the cab, the auxiliary sound system can emit sound to the outside of the car. The sound is not only soft but also the volume is relatively low, and the maximum at a distance of 2 meters does not exceed 50dB.

[0012] When the windows are closed, people in the car often cannot hear the sound from the auxiliary sound system to the outside of the car. In this case, a switch prompter can be installed in the cab on the basis of the above-mentioned auxiliary sound system. The switch prompter is...

Abstract

The invention relates to the assistant acoustic system on vehicles, with volume less than 50db. It is a complement to the existing horns on vehicles in order to allow the driver warning pedestrians without shocking them with loud noises of the horn. It can be intermittent, with audio play and harmonic tunes. It can also send hint information inside the driving chamber, allowing the driver to realize the on of the acoustic system with the window closely shut to turn off the system.

Description

1. Technical field [0001] The invention relates to a sounding system installed on a car, which is suitable for reminding people outside the car to pay attention to the car. 2. Background technology [0002] Cars are one of the symbols of modern society. People deal with cars almost every day in their daily life and work, and cars encounter pedestrians on the road almost every day. As everyone knows, every car is equipped with a horn to play the effect of sounding to cars or pedestrians, which is a traditional car sounding system. But in the present situation, the loudspeaker volume that is installed on the car is all higher, and the loudspeaker volume of general car is about 120 decibels (dB) basically at 2 meters away. This high volume is used so that people in other cars can hear the sound of the horn with the windows closed. But there are downsides to this high-volume sounding. For example, such a high volume has a disturbing effect on pedestrians on the road, especial...
