What happens when you change the horn and make it quieter?

If you change the horn and the sound becomes smaller, it means that the horn and the circuit are not matched, for example, the circuit requirements are 3 ohm horn or 4 ohm horn, you change it to a 16 or 32 ohm horn, so that in the case of mismatch, the sound of the horn is relatively small.

It shows that the horn does not match, it depends on how much impedance the original is, and only the same sound is the same as the original.

The sensitivity of each horn is different, the larger the paper cone, the stronger the magnetism, the more turns of the voice coil, the softer the support frame, and the higher the sensitivity. Generally speaking, the sensitivity of brand-name speakers is relatively high, and some can reach 92db.

The sensitivity of the horn is different, and the sound is not the same...

The reasons why car horns become quieter are:

3) Electromagnetic interference - this cause is more complex, many electrical equipment connected or not connected to the computer may cause electromagnetic interference, but it is easier to investigate, that is, the sound is very small, and the lack is not a little volume; And the volume is unstable, once the interference is weakened, the volume will become normal or relatively loud. Or, plug in and unplug the speaker plug, maybe the volume is normal, this can be checked.

4) Speaker volume knob - all turned on to the maximum, if the quality is fine, this one does not need to be checked.

5) Maybe the speaker brocade wire is broken, or the speaker paper cone is damaged.

6) Short circuit of speaker output, resulting in short circuit of car audio power amplifier, output protection; The sound is small.

7) The amplifier block is damaged.

8) The diaphragm contact gap has changed. Adjust the contact gap adjustment small screws on the horn to bring the sound back to normal.

It is recommended to send it to an after-sales service point for repair.

Car horns are the most commonly used device in the daily use of automobiles. It is precisely because of the use of the long cave clearance period that various failures will inevitably occur. Today, let's talk about the various reasons why car horns are broken.

1.The horn is damp.

Automobile horn devices generally have good sealing performance, but with the increase of service life and times, it will inevitably lead to the decline of their sealing performance. As a result, moisture and the like may enter the horn when washing the car, causing frequent problems such as the horn sounding or not sounding before the horn is heard.

2.The speaker circuit is damaged.

If the owner likes to press the horn for a long time while driving the vehicle, this will cause the resistance of the horn contact to be too large, which will lead to the weakening of the current of the horn circuit and the solenoid coil, and finally lead to the hoarse or silent failure of the car horn.

3.The horn button is broken.

If the driver needs the car horn to sound, he and she need to press the horn button. If he and she press the horn button for a long time, it will also be damaged. The damage of the button is also one of the factors that does not sound the horn.

4.Poor contact.

In some models, the internal solenoid end mammoth is not connected by welding, but by aluminum rivets. At this point, if the insulating paint of its ports is not properly treated or the links are not in place, it will lead to poor contact.

Solution: We can solve the corresponding problem according to the fault phenomenon. If the horn is silent, we can first check whether the line and button are normal.

If everything is normal, we can solve the problem by replacing the horn. If the horn sound becomes smaller, we can solve it by adjusting the gap between the horn core and the armature. If the sound is loud, the gap between the core and the armature increases; Otherwise, if it is small, the gap will decrease.
