The car instrument panel prompt sound, why are some good and some are low?

If you drive a car 20 years ago, when you turn on the turning light, you will hear a rhythmic "jam" sound from the center console. This is the sound of the flash relay of the turning light. Mechanical sound of metal knocking.

Because the application of early electronic technology in the car is not extensive enough, the effect of turning lights needs to be controlled by relay. The electrical electrical electrical electrical electrical electrical electrical electrical electrical electrical magnetic absorption and release of the described iron contact to control the regularity of the current, the turning light can flash. When touches the touches, the sound of "click" sounds.

Now that the flash relay has already been replaced by the integrated circuit. Although you will have a "bar" prompt sound when you turn on the turning light, this sound is emitted by the bee tweezer in the instrument plate. Moreover, this bee tweezer almost captures all the prompt sounds in the car, such as reversing radar, handbrakes that have not been released, the door is not tightened, the seat belt is not tied, and so on.

Why does a bee ring make so many sounds?

Someone will be puzzled: Why can a bee tweeter make so many sounds? Why do some car instrument panel prompt sounds so nice, but some cars' instrument panel prompt sounds are so low?

Because the bee lumator on the instrument panel is only responsible for sound, you can make different sounds to enter different signals. The simplest driving method is to control it through different frequencies and time, but this is the simple "tick" sound, just like the electronic meter 20 years ago, very low.

If you want to make a better sound, you must provide a more complicated control signal for the bee tweezer, and use a more complex driving circuit so that the beeuris can make the "Ding Dong" style on the high -end car. The sound of pleasant hearing.

To what extent is the in -car prompt?

This is to talk about BYD's NVH active sound system. This system directly pushed the car sound system to a new height.

What is NVH

NVH N represents noise (noise), such as wind noise, tire noise, engine noise. V represents Vibration, such as the vibration of the engine during driving, the vibration of the chassis, the vibration of the body metal plate, the vibration of the steering wheel, and the vibration of the transmission system. H represents Harshness, mainly the impact of vibration and noise on human senses.

In simple terms, the performance of a car NVH determines the level of hearing and touching when driving. The NVH performance is everywhere with abnormal vibration and noise. The NVH performance will be more quiet and comfortable to drive. You can only find the car visually at high speed, and you can't feel how fast you don't feel the car.

At that time, some domestic cars were ridiculed to "no except the horn sounded", "the speed exceeded 80 and the co -pilot spoke by roar." Although this statement was exaggerated, it also reflected the situation to a certain extent. Because the early domestic cars were more advantages because the price of the vehicle was cheaper, and it did not pay attention to the quality of vehicle quality and the creation of driving comfort.

After all, there are too many things to be studied NVH. You must know that the car body is stamped with steel plates, and there are a lot of various cavities and holes. Both are good birthplace and transmission medium of vibration and noise. If you want to understand NVH, you need to invest in various experimental equipment and professionals.

But now when you mention NVH, the waist pole of domestic cars is very hard. On the one hand, domestic cars have developed rapidly in terms of technology and sales. Everyone wants to try a higher quality life. On the other hand, the brand premium capacity of domestic cars is lower than foreign brands. Therefore, relying on rich and configuration and higher quality to provide higher cost -effective products is also a means to attract consumers.

For example, the picture above is the comparative test map of BYD Han. At a speed of 120 kilometers per hour, the level of noise control in the car can reach the level of German luxury cars. This is a good example.

Higher realm in the car: active sound system

The active sound system is a very fun thing proposed by BYD. In layman's terms, it is the various sounds on the car.

First, it increases the sound effects of car start, flameout, and welcome. Secondly, the system's prompt sound is made more detailed, and it matches the exclusive music of different styles according to the style of different models. There are exclusive background music when you start the vehicle and the flameout. When the car is driving, there are exclusive pedestrian tips, and there are pleasant sound effects when operating various keys. And the traditional prompt sound of the car has also been refined design and creation, which can be said to be refreshing.

Some people may say that this is not to increase some sound effects. What is amazing? To say, it is really not difficult to achieve in technical. But it is not so simple to get good results.

Dynasty series: the elegant atmosphere of Chinese style

Nowadays, Chinese style music is particularly popular. Why do some music be full of Chinese taste? Because the vast majority of Chinese style music is created based on the ancient Chinese five -sound tuning. Gongshang Jiao Zheng Yu, Qinqi, calligraphy and painting, this is a valuable cultural heritage left by the ancestors.

For example, the pure music "The Memory of the Forbidden City" is magnificent and magnificent. Although it was created by Japanese composers, it was created by feather tunes in the Chinese five -tone tuning.

The exclusive music of BYD's dynasty series models is created based on the Chinese five -sound tuning, and it is interesting to use the mainstream instruments of the mainstream instruments in the dynasties. For example, BYD Tang's exclusive music uses the pipa sound, and BYD Yuan's exclusive music uses the sound of the piano, which is very cultural. Ocean series: natural fashion

When you sit in the marine series, you will sound a pleasant sound in the car after pressing the start button, as if you are in a dreamy ocean. The vehicle will emit a fresh and bright pedestrian reminder during driving, light and agile.

The active sound of the marine series is based on the theme of small tones, and the consonant is mainly wave elements, smooth and bright. The marine life series introduces the beautification bionic sounds such as dolphins, seagulls, and seals to increase interest and vitality. The warship series introduced the sound elements of the virgin whistle and the waves to beat the hull, which was ingenious.

And if you want to express the best effects in various sound effects, the quiet inside environment is also necessary. Just like you must find a quiet place for tea, there is no kind of mood on the noisy street. Therefore, the active sound system needs to cooperate with good NVH performance to truly touch the heart of consumers, and this is what BYD really wants to present to the owner.
