Car horn speakers are what we commonly call car horns. This device must have been seen before. Its role is to send necessary acoustic signals through the operation during the running of the car to warn pedestrians and cause other vehicles to pay attention to ensure traffic safety. At the same time, it is also used to urge and transmit signals. Since it has such a big role, we need to be more careful when we choose. The following describes the correct selection method for everyone.

Pay attention to sound quality

At the time of selection, many people easily enter a misunderstanding, that is, only pay attention to technical parameters and do not pay attention to sound quality. In fact, the specification of technical parameters on many shoddy speaker specifications is very good. It is a false one. Do not let the appearance be deceived. The technical parameters of the speakers must be seen, but because the materials are not the same, the process is not the same, the structure is not the same, and so on, the sound quality of the speakers will be very different. Like the human voice, the timbre is not the same. Therefore, when we choose, we must pay attention to the sound quality of car speakers.

Attention volume

Many people think that the louder the volume emitted by car horns is, the better, so they use this as a criterion when selecting them. Actually, this is not correct. This is because long-term listening to music in a loud environment will cause great harm to the ears. I believe many people have seen large-caliber tweeters that were previously used for broadcasting. The kind of speakers that can be used for loud sound can be used to enjoy music. Therefore, when choosing a horn, we must balance the performance of high, medium, bass, and timbre, rather than the monotonous pursuit of loudness.

Pay attention to the quality of the speaker

Many people did not consider the speaker as one of the main factors when choosing a car horn. In fact, if you use the same platter, push two pairs of different prices, but the parameters are basically the same speaker, you will have experience after audition, high quality and good performance must be good.
