With the popularization of modern electric vehicles, the installation of low-speed warning sound systems for electric vehicles has become particularly important. Vehicles equipped with low-speed warning sound systems can effectively emit sound to remind pedestrians and other vehicles of their driving status, making vehicle travel safer and effectively reducing the occurrence of dangerous accidents. Therefore, installing low-speed warning sound systems for electric vehicles is an imperative task for people today.

1、 Why is this a serious matter
According to incomplete statistics, more than 2000 people are injured in accidents due to the silence of pure electric vehicles each year. Therefore, it is stipulated that pure electric vehicles and some hybrid models need to issue an alarm when the speed is below 30km/h, and sales models must be equipped with a mandatory low-speed warning sound system for electric vehicles. Similar laws have also been published abroad. The regulations of the European Union are more detailed, and cars need to emit a warning sound between starting and 20km/h. Specifically, when the speed is above 10km/h, a sound of 50-75dB needs to be emitted; when the speed is above 20km/h, a sound of 56-75dB needs to be emitted; and when reversing, a sound of 47dB or more needs to be emitted. In China, there are currently no mandatory regulations or plans regarding vehicle sound warning systems. However, some car companies have voluntarily installed low-speed warning sound systems for electric vehicles in the models of self owned brands on the market.
2、 Why is this matter related to environmental protection?
Invisible pollution is also pollution, such as the noise we are talking about. Many elevated roads near residential areas are equipped with soundproof panels to shield the noise generated by high-speed vehicles. It can be seen that we are deliberately limiting the spread of this pollution. However, due to the structure of fuel vehicles, there is currently no particularly effective technology to alleviate the uncontrolled spread of noise at the source of pollution. This is also a characteristic and direction of current research on low-speed warning sound systems for electric vehicles: it does not completely imitate the noise characteristics of fuel vehicles, nor does it purely record engine recordings. Instead, it is synthesized through a digital signal processing unit, automatically adjusts the volume according to the speed of the vehicle, and emits directional sound. In this way, it can not only remind pedestrians on the road to pay attention to safety, but also minimize noise, solving the noise problem in the era of fuel vehicles.
3、 What business opportunities are implied in the sound?
In the context of the increasingly mature new energy vehicle market, the launch of these millions of new cars will inevitably be equipped with low-speed warning sound systems for electric vehicles. Currently, the cost of a waterproof speaker and control unit sound device (PAAS) is around 200 yuan, and this potential market size can be imagined. For automotive parts manufacturers, it undoubtedly opens up huge development space and new profit points in the future.
