Chapter 146 Speaker
The progress of the speaker is obviously much faster than that of the microphone. You can test it after the glue is dry. You don't even have to rush to apply the paint. It's the test first anyway.
Populus euphratica's craftsmanship is not bad, the cabinet is very straight and smooth, he is qualified as a carpenter, and the dimensions are all in line with the standards. This is enough. Just make the standard ones first, and then learn how to modulate them with Wang Xu.
Speakers are similar to musical instruments to a certain extent. They all rely on resonance boxes to spread sound, so a pair of good ears is the most important tool for making speakers.
Hu Yang has been engaged in music for two years. Although he failed, it still allowed him to distinguish the quality of sound with his ears, and he also developed his own pursuit of aesthetics.
Wang Xu made a large number of combinations of different speakers to find the sound he expected. With the same sound source and the same power amplifier, it was easy to compare the differences in the sound quality of the speakers. Well, maybe it was just easy for Wang Xu.
Many people have heard the saying that the treble is sweet, the midrange is stable, and the bass is deep. These are the most basic requirements for a good speaker.
In fact, the treble needs to be bright, transparent, and penetrating. If you are playing rock music, it is best to have some metallic texture.
The midrange needs to be natural and accurate, especially the vocal frequency band in the midrange, which should not be too exaggerated or too suppressed. This frequency band is the frequency band that people are most exposed to, and it is also the key frequency band for information expression, so it must be accurate and clear.
The bass needs to be crisp in addition to being deep. This is not the crisp crispness of the treble, but the bass frequency is low and the diameter of the speaker is large, which is especially prone to aftershocks that are too long.
This can easily lead to confusion of the bass, excessive duration, etc. Being crisp means not procrastinating when you have to stop, and end it neatly.
Before the previous sound ends, and the subsequent bass comes again, they will overlap each other, forming a vague effect. This situation particularly affects the listening experience. Many times, you will feel that the bass is particularly messy, which is caused by this ambiguous feeling.
This confusion may be a problem with the speaker, or it may be a problem with the resonance box. Of course, it is more likely to be a problem with the combination, or even related to the placement and surrounding environment. Either way, system engineering is extremely complex, and inadvertent adjustments may lead to changes in the overall effect.
Things like speakers were actually very mature in the 1990s. Most of the speaker technology and speaker technology had already come out, and the new technology failed to trigger any special revolution.
So this is actually an area with little innovation. Just like microphones, highly sensitive microphones from the Second World War can already hear the calls of dolphins hundreds of kilometers away.
Of course, it can be more sensitive now, but that is just due to the development of circuit components and has little to do with the technology of the microphone itself.
Therefore, the technologies that Wang Xu has developed from speakers and microphones are all related to materials. However, there is still one field that has not really developed at this time, and that is the field of active speakers.
This is an integrated system that integrates a series of circuits such as signal decoding, filtering, and power amplification directly into the speaker. It can directly receive ordinary audio signals and then play them directly.
This kind of speaker requires an independent power supply, so it is called an active speaker. In this era, this thing is also called a multimedia speaker, and the whole world is currently in its infancy.
This is a by-product of the development of computers. With the widespread popularity of personal computers, there are more and more applications on computers. Since the 386 era, various multimedia applications have appeared on personal computers, and the ones on computers can only emit crude The sound speakers are completely inadequate.
As a result, some large and small solutions began to appear in various places, and active speakers were one of them, and this thing was the weapon Wang Xu prepared for the market.
The effect of active speakers can actually be very good. In later generations, there were even active speakers with a unit price of more than 100,000 yuan. The effect of those speakers is actually very good.
However, active speakers are generally not too big, so the bass effect is often mediocre, and the internal circuits are more or less affected by sound vibrations, and there will be some defects when related to each other, so they will not be used in real listening rooms. Active speakers.
Active speakers are a market-oriented product for the public, while listening rooms are professional audio equipment and cannot be compared in the same way.
Wang Xuguang spent several days tinkering with various speaker combinations before finally settling on several combinations.
He first chose a simple combination of standard one bass, one midrange, and one treble. This is the top product he prepared for the listening room, and it is carefully crafted from materials to processing.
Wang Xu purchased a lot of parts, including dozens of speaker types and thousands of combinations. He didn't have much time to do too many experiments, so he could only start with the simplest ones.
The listening room has been renovated a long time ago, and everything from soundproofing equipment to special sound-absorbing curtains has been installed. However, the equipment is still supported by the rented landscape.
Wang Xu's new speaker is more than one meter tall and contains a 12-inch large woofer, a five-inch midrange speaker, a tweeter, and a bass guide hole at the bottom.
The style is very simple, nothing fancy, with dark brown cherry wood grain, and the overall image is square and square. There are four thick and short metal support legs underneath, revealing the only bright color.
The cabinet has rounded small chamfers, creating a sense of cutaways. The front cover panel is an ordinary black mesh, and the bottom is a dark guide hole like a big mouth.
The front cover panel included in the system is a kind of mesh with good elasticity. Wang Xu hasn't taken out that thing yet. Alas, maybe the material department will make a fortune again. If this continues, Wang Xu estimates that the Department of Materials will have to set up a special laboratory for himself.
The speaker as a whole shows a rough aesthetic, which is a unified design that matches the violent aesthetic style of the tube amp. As a designer, how can you ignore the creation of an overall atmosphere.
It can be said that Wang Xu is quite satisfied, at least the shape is quite domineering. In the context of the end of the Soviet Union, using their once unparalleled vacuum tubes as amplifiers and designing such a speaker with a violent aesthetic style can be regarded as Wang Xu's contribution. Let’s commemorate this once glorious red empire.
It's just that Wang Xu won't mention this background, let alone publicize it. The trend at this time cannot miss this. Maybe it can be mentioned in his memoirs decades later. Wang Xu felt a little emotional.
As soon as the pair of speakers were processed, Wang Xu couldn't wait to install them in the listening room. The seats and placement in the listening room are specially designed and planned. All you need to do is move the original equipment.
Then put Wang Fei's latest CD into the disc player, sit comfortably in the best listening position, and enjoy it quietly.
The sound of heaven comes, and Wang Fei's gentle breath seems to surround you. Every word spoken and every breath inhaled are clearly and brightly restored, as if that woman is singing for you right next to your ears.
