How to see the speaker crossover
When we buy a speaker, it’s not just about powering up and connecting the cable to enjoy a perfect listening feast. If we want to have the best high and low frequency, we need to add a speaker crossover to the speaker. So what is a speaker crossover? How to plan the circuit of the speaker crossover?
What is a speaker crossover?
The speaker splitter is a combined filter that can distinguish the sound signals of different frequency bands, amplify them respectively, and then send them to the speakers of the corresponding frequency bands for playback , so that the playback characteristics of each frequency are more balanced and consistent.
What is the function of the speaker crossover
The function of the crossover is equivalent to the “brain” in the speaker, and the crossover is good for the sound quality Bad plays a vital role. Using the frequency divider can send the high frequency signal to the tweeter, and the low frequency signal to the woofer, so that the high and low frequency signals go their own way, and try to give full play to the advantages of the working frequency band of the respective speakers, so as to ensure the speakers of different working frequency bands. Give full play to make the playback characteristics of each frequency more balanced. Therefore, it is not difficult to see that a well-designed frequency divider can better exert the characteristics of the unit, so that the sound can play a better quality.
The circuit diagram of the speaker frequency divider
From the working principle, the frequency divider is a filter network composed of capacitors and inductance coils. The treble channel only allows high-frequency signals to pass through and blocks low-frequency signals; the bass channel is just the opposite, allowing only the bass to pass through and blocking high-frequency signals; The intermediate frequencies can pass through, and both high and low frequency components will be blocked.
The speaker frequency divider processes the music signal output by the power amplifier through an internal filter element, so that the signal of each unit with a specific frequency passes through. The speaker crossover circuit diagram can clearly show how to effectively optimize the combination according to the different characteristics of the speaker unit, so that each unit can maximize its strengths and avoid weaknesses, so as to give full play to their respective potentials.
In the design process of the speaker crossover circuit diagram, if you need to balance the flexibility difference between the high and low units, you can also add an attenuation resistor; if you need to smooth the impedance curve of the speaker, you can also increase There is an impedance compensation network composed of resistors and capacitors.
