Analysis of Speaker Power Control System Based on Automobile Mechanical Structure Characteristics

Cars gradually became the main means of transportation. However, every advantage has its disadvantages, and urban congestion caused by driving is becoming more and more serious. The main reason is that the driving level of drivers in our country is generally low, and the growth rate of vehicles is much higher than the road construction speed, which will inevitably cause congestion. Many drivers will inevitably become irritable and honk their horns too much, and the volume of vehicle horns is currently too high. Speakers that are too loud are bound to scare pedestrians and worsen traffic congestion. Therefore, we must conduct necessary research on noise. In order to ensure that the sound of car horns cannot only alert pedestrians and attract the attention of other vehicles, but also ensure the effect of bringing noise to the urban environment, many domestic experts and scholars have conducted in-depth research on the types of car horns. There are some characteristics of sound. Research has found that the sound of the whistle is closely related to the power of the speaker. Therefore, according to the mechanical structural characteristics of the car, this paper designs a power control system including a power module, ranging module, main control system and display alarm system. The main control system is the core of the entire power system, mainly completing the collection, output, display and alarm system control of signals. The power module mainly completes the driving work of the speaker.
