What are the solutions to the tweeter noise of car speakers?

1. Connect a capacitor in parallel between the horn button contacts of the steering wheel. For the noise generated by the relay electric horn, the main elimination methods are as follows: the electric horn bracket should be in good contact with the car body. At both ends of the relay contacts, a capacitor is connected in parallel, or a capacitor is connected in parallel at both ends of the contact.

2. There is interference, such as the quality of the power supply filter circuit is not good enough, and the power supply transformer has not taken shielding measures. You can replace the shielded transformer and make a better rectification filter circuit, and the shell is unshielded., there is radio interference. Metal shell, iron plate, stainless steel and other materials can be used, but aluminum and copper are not effective.

3. The solution to the sound of car speakers: replace the audio cable or the speaker. If there is a sizzling sound from the car speaker, the audio cable can be replaced. If there is a quality problem, the speaker can also be replaced. If the location of the place that causes the noise is different, the solution is naturally different.

4. Interference of high-power electrical appliances (electric horns, motors, etc.). 3 items are related.

Does the car tweeter need a capacitor?

1. Car treble generally uses 1uf~7uf capacitor and inductance. The speaker is the audio signal device of the car.During the driving process of the car, the driver emits the necessary sound signals according to the needs and regulations to warn pedestrians and attract the attention of other vehicles to ensure traffic safety and also use it to prompt and transmit signals.

2. Whether you modify the sound system or not, the sound circuit itself determines the indispensable of capacitors.

3. The tweeter adds capacitor to prevent the bass current from passing through the tweeter. It uses the inverse relationship between the capacitance of the capacitor and the frequency to isolate the bass current, and prevent the capacitor from resonating in series with the tweeter, and add a resistor for damping.

4. It is necessary to add capacitors. The electricity requirement of "car audio" is to make the electricity generated by the generator reach the electrical equipment (such as "host", "amplifier") as much as possible without loss, while taking into account the safety of the vehicle.All the electricity used in cars comes from generators, just like water in cities comes from rivers or reservoirs.

5. Both the middle and the treble do not need capacitors, and the middle is mainly the vocals. If you don't have the original amplifier, the sound field will be messed up, and the effect will not be good. If you use the central frequency divider alone, you can connect the central frequency divider without an amplifier. The key to the sound system is the selection of materials. Matching is very important. There is no need to put it in the middle, which will affect the sound effect of the system.

6. There is a tweeter divider in the car, and its own capacitor has a certain impact. In fact, the built-in capacitor is the first-order frequency divider of the tweeter. Unless there are enough reasons, there is no need to install a tweeter divider. Because the modification of the external frequency divider requires the original frequency divider capacitor to be skipped.

Where is the most suitable high-pitched tone for car audio?

So generally speaking, it's okay to play all of them in the middle. The treble can be slightly raised, and then slightly changed according to your own habits. At the same time, it is recommended to find an experienced master to help tune, because the car audio is a three-point equipment and seven-point debugging, so the tuning step is really important.

Which position is the best to tune the high and bass of the car audio: the treble to 100%, and the bass to 50%. The sound effect setting steps for low-end models are as follows: Setting button: The SET key is used to set the sound effect. Press the SET key to enter the sound effect and clock setting interface.

High school bass + - do not exceed 3; for example: treble +1, bass + adjust the bass of the entertainment setting to 8-9 (if the low frequency is distorted, tune it smaller) in the middle tone to 2-3, the treble to 5-6, the left and right equalization to the middle, and the front and rear balance are also tuned to the middle.

According to the auditory experience of ordinary people, the treble adjustment of the car stereo is generally fixed or raised by 1-2 grids, and more than 2 grids will be harsh and uncomfortable; the music is mainly in the middle, which can be adjusted up and down 2-3 grids. Attenuation of more than 3 grids is easy to lead to the attenuation of the middle tone, and adjusting more than 3 grids will cause distortion of the sound effect.

The adjustment of the bass is a key to the car audio system. A good adjustment will make the sound change dramatically. ( It's best for two people to debug the bass, one in the car and the other in the back).

How to tune car treble bass

1. How to tune the best high school bass of car audio? Tune the whole sound field forward 2 Or 3 grids; high school bass +-do not exceed 3; for example: treble +1, bass + adjust the bass of the entertainment setting to 8-9 (if the low-frequency distortion is made smaller), the middle tone is adjusted to 2-3, the treble is tuned to 5-6, the left and right equalization is adjusted to the middle, and the front and rear balance is also adjusted to the middle.

2. High school bass +-do not exceed 3, treble +1, bass +2, tune the whole sound field forward 2 or 3 squares, high school bass +-do not exceed 3, treble +1, bass +2.

3. In the car multimedia audio settings, you can find the treble and bass adjustment, and you can adjust it from there. In fact, the car is similar to the reverberation room of a speaker. Individual songs can be adjusted according to the owner's preferences, but generally speaking, all the midrange can be played.

4. You can dial the filter to the HP position and adjust the frequency division knob to 60Hz, 70Hz, 80Hz, 90Hz or even 100Hz. In the car multimedia audio settings, you can find the high and bass adjustment. The car is similar to the reverberation room of the speaker.

How to adjust the bass and treble of the car audio

Basic models should be in the sound settings of the CD player, adding a little bit of treble and bass each, and the midrange to 2.

And the frequency division point of the tweeter in some parts of Qualcomm is about 60HZ~90HZ. Car audio debugging steps and methods Preparation: First, restore all the additional functions of the car host to the factory state, and then put the high, medium and bass in the middle. Of course, the left and right balance is the same.

If the original car is the front two and the rear two, that is to say, there is no tweeter in the whole car, it is recommended to increase the tweeter. If the whole car is front four and rear four speakers, adjust the balance of the front and rear left and right, and add or subtract the high bass appropriately according to the hearing. If you want to get the best effect, you'd better find a professional to tune.

How many square lines should be used for car tweeters

0.5 square meters is enough for car tweeter. In actual modification, the tweeterThe power of the speaker is generally less than 100W, and under normal circumstances, it is between 20-60W, so the most suitable wire is the treble with 0.5 square speaker wire. The institution that can decode software and multimedia is called the sound source.

Generally use 2. 5 to 4 square copper wire. Generally, 5 to 4 square copper wire, or No. 12-16 finished speaker wire is used. Use the thick one with high power, and use the thin one with low power. Coaxial speaker, that is, a speaker with treble and bass, one top two.

.5 squares. Danna car speaker belongs to the treble car speaker, and the treble car speaker is the most suitable wire with 0.5 square speaker wire. It is a wire specially used to connect the amplifier and the speaker. It is responsible for connecting the parts of the speaker and transmitting the power of the amplifier to the speaker.

Generally speaking, the square of the Toyota amplifier speaker wire should be 5 square feet. If your speaker power exceeds 100 watts, you should use a 4-square-foot wire. In addition, you can also determine the square number of the required wires according to the power of the speaker.

No. According to the relevant information of the car snail siren horn, it is not allowed to use 1 square wire. Two currents of about 5A of the horn are equal to 7A current. If the power of 1 square wire is not small, it will not be able to use it. It is better to use a wire larger than 5 squares. The horn is the sound signal device of a car.
