Thinking about making speakers in amateur <1>
Speakers occupy the most important position in the sound system, which has been recognized by everyone. Because it is the final gateway to music restoration, that is to say, the audio signal is finally restored from the speaker (speaker) to sound; it is conceivable that the quality of the speaker (including the sound quality, efficiency and balance tone) is crucial for the entire sound system important.
Amateur DIY speakers are the most affordable and most successful. Many people say that DIY speakers cannot be successful in amateur conditions, but I think it is different now. The progress of society and the development of technology have provided more than good conditions for industry enthusiasts. For example, there are many good-quality speakers and crossover components available for purchase, technically assisted by network experts, etc .; in the audio system, the speakers involve the least electronic knowledge, and enthusiasts can basically master it through short-term study The method of DIY speakers is of course not easy to do well. The key to correct thinking is the accumulation of experience.
The difficulties of DIY speakers are mainly in two aspects: one is the production and adjustment of the frequency divider, and the other is the design of the cabinet structure; fans should avoid the heavy weight to determine what kind of speakers to make, which is the first step towards success.
I talked about this today. I have a limited level and insufficient experience. I just try to tell my fellow friends what I think of. Please criticize and correct me!
Thinking about making speakers in amateur <2>
Personal abilities are always limited, so it's a good strategy to grow up and avoid weaknesses, especially for amateur DIY. After analysis, the author believes that there are three speaker systems that are more suitable for amateur DIY:
<1> Two-unit two-divider bookshelf box.
<2> Three units and two frequency division floor boxes;
<Three> Three units 2.5-frequency floor box; the following is a brief analysis.
1) Two-unit two-frequency division: This is the most common and classic system. Its advantage is that the frequency division network is (relatively) simple and the cabinet is also more convenient to manufacture. The production of this system should first pay attention to the choice of speakers and the combination of treble and bass.
2) Three units and two crossovers: in fact, it is the expansion of the previous system, that is, adding a same mid-bass unit (with parallel and series methods) to enhance the low frequency response of the system; therefore there is only one crossover point, but There are many variations of the cabinet.
3) Three-unit 2.5 frequency division: It is also extended on the basis of the first type system, that is, adding a subwoofer unit, although there are two crossover points, but the subwoofer (passive) crossover network is very simple, So it's not too difficult.
At present, almost all DIY kits are nothing more than these three modes, which are for the convenience of amateur DIY enthusiasts; and the three types of finished boxes on the market also account for the vast majority, which shows that manufacturers are also trying to pick simple work , So the success rate is high! Next time I will talk about the purchase of the unit and other issues. Everyone is welcome to criticize and correct, thank you!

Now that I have talked about it, let me talk about the purchase of the speaker unit:
For those with certain hearing ability, you should first consider that the sound of the speaker is your favorite. The sound of the speaker is mainly determined by the material of the cone. There is a lot of content here. Please refer to the relevant information. It is best to have heard it.
Second, we must fully consider the effective connection between the tweeter and the mid-bass unit, such as: the upper limit of the ordinary mid-bass unit is only about 5KHZ, and the lower limit of the treble is only about 3KHZ. This is still the manufacturer's information. It is difficult to guarantee, so it can be seen that the crossover point is only 3KHZ-5KHZ, and the upper limit of the fever mid-bass unit is 7K--8KHZ tweeter unit, the lower limit is 1K--2KHZ, so the mid-bass and tweeter units are best. One is the fever unit. (Take 6.5 inch as an example)
It is extremely undesirable to buy two high and low basses on the street, and then make a crossover and box according to a book. Such a unit has no parameter quality and no guarantee. It is absolutely necessary to buy a brand-name unit of the old factory; it is best to buy a kit The success rate is high, and the profit of about one hundred yuan is to be given to the merchant. But don't buy high-priced kits such as Hivi. Can't do well and cost money! The box system is the advantage of DIY. You can give full play to your imagination. The deeper you understand the theory of speaker construction, the better you will do. I sincerely wish everyone success in DIY speakers!
