The role and characteristics of audio electronic crossover

　　Through the above introduction, everyone should have a general understanding of electronic frequency dividers, so what are the functions and characteristics, and even disadvantages of using frequency dividers? Based on years of work experience, I have summarized the following points:

　　(1) Functions and characteristics

　　1. Basic frequency division task: As there are many types of speakers nowadays, what kind of function and frequency division electronic frequency divider should be used in the system still need to be flexibly configured. The electronic frequency division commonly used now has 2 frequency division and 3 division. It is too complicated and meaningless to distinguish between frequency and frequency division by 4 if it exceeds frequency division by 4. Of course, the current electroacoustic technology is changing with each passing day. At present, there are still some frequency dividers that can also process the audio signal in other aspects while dividing the frequency. However, the main function and task of the electronic frequency divider is of course the frequency division. .

　　2. Protect the speaker equipment: We know that the working frequencies of different speakers are different. Generally speaking, a speaker with a larger caliber has better low-frequency characteristics and a lower frequency dive. It seems that under the same circumstances, the bass effect of 18-inch speakers is generally better than that of 15-inch speakers; on the contrary, speakers with smaller diameters should be used in the midrange part, because the diameter of the current cone vibration speakers is usually The smaller the sound, the higher the frequency; and so on, the vibrating diaphragm of the high-pitched part should also be small in order to emit high-frequency sounds. Since the speakers are so complicated and there are so many types, how to ensure that they can work safely and effectively becomes very important. The electronic crossover can provide the best working frequency required by different speakers, so that various speakers can work more rationally and safely. Imagine: If the mid- and high-frequency speakers in the system are not divided by the electronic crossover, but directly use the full-frequency audio signal, then these mid- and high-frequency speakers will be easily damaged under the impact of low-frequency signals. Therefore, the electronic divider In addition to the frequency division task, the more important function of the normal use of the frequency device is to protect the speaker equipment.

　　3. Increase the level of sound: If there are many different types of speakers in a sound system, and indeed no electronic crossover is used, and different types of speakers use undivided full-frequency signals, there will be a difference between different speakers. There will be a lot of overlapping and repetitive parts of frequency, acoustic interference will become serious, the sound will become fuzzy, the sound field will be very poor, and the microphone will be prone to acoustic feedback. If an electronic crossover is used to divide the frequency reasonably, so that the different speakers are in the best working condition, so that the frequency range of the sound emitted by the different speakers will hardly be repeated, thus reducing the phenomenon of sound waves interfering with each other. , The sound will become extra clear, the tone will be better and more layered!
