Do speakers have to be boxed to hear good sound quality?

Sound quality, in addition to the quality of the speaker device itself, is also closely related to the cabinet structure of the speaker, which is determined by the structure of its sound working principle.

1. In layman's terms, the audio current pushes the vibrating membrane and paper cone of the speaker, and moves back and forth with the amplitude of the audio signal, so that the air vibrates and spreads sound. The sound waves generated before and after the paper cone are in opposite phases. When two sound waves of different phases meet, like a ripple caused by two stones thrown into water at the same time, it will interfere and disrupt the normal spread of the waveform.

The same is true of the propagation of sound;

2. The speaker was born to solve this problem. The speaker has a closed type, and there is an inverted type:

The closed speaker can lock the inverted sound wave in the cage, and weaken it with the sound-absorbing material in the box, and use the damping effect to avoid the influence of its low-frequency resonance point;

The inverted speaker, through a special design, reverses the sound wave phase in the box by 180 degrees, which is called "inverted phase". This inverted sound, coming from the inverted hole, is synthesized with the forward sound wave, which can increase the intensity of the sound wave;

3. The sound emitted by the speaker can only be restored to the pure sound quality of the signal source after the reprocessing of the speaker. Those speakers that cost tens of thousands of yuan at every turn, their best is also a symbol of their high sound quality, high precision, high technology, and high quality. In fact, you can also experience the sound quality of different speakers by comparing the sound effects of mobile phones, tablets, laptops, TVs, computers, and Hi-Fi speakers.

The woofer must be mounted on the speaker to make a good sound.

The speaker is designed for woofers; The treble doesn't do it with a speaker.

There is a speaker to close the sound, you can also find a bowl to buckle on the speaker, which is also a bit effective.

If the speaker does not have a speaker, the sound before and after the speaker will cancel each other, mainly the bass cancels out, there is no bass, and the sound is much smaller.

If you use a large board --- a baffle and separate the front and back of the horn, so that the sound before and after the horn will not be canceled out, the bass will be there and the sound will be good.

The first to use this kind of large board to make speakers, because the area of the board is large, it is inconvenient to use, and later invented the speaker - that is, the principle of the speaker baffle.

Now there are also audiophiles playing with baffle speakers - the back of the speaker is not closed, that effect, and the current speaker has some differences, it feels like the sound is more natural--- in fact, the effect is similar, different speakers have different effects.

Summary. When installing a speaker box, the resonance of the cabinet will be generated, and if the resonance frequency is close to the working frequency of the speaker, it will have an impact on the sound quality. A common solution is to reduce the resonant noise of the cabinet by adding vibration isolation materials, such as sponges.

In addition, the design of the cabinet is also one of the factors affecting the sound quality, and a reasonable cabinet design can improve the sound quality performance. Therefore, if the boxed speakers do not meet the requirements, you can try to add vibration isolation materials or replace the more suitable cabinet to improve the sound quality.

The speaker is no problem to listen to the monomer, but it is not good to pack the box.

Excuse me, but please go into more detail?

Summary. In response to this problem, it may be that there is a problem when packing the box, it may be that the method of packing the box is incorrect, or the material of the box is not suitable, or the tool for packing the box is not perfect. Workaround:

1.First of all, it is necessary to determine whether the material of the box is suitable, and if not, the suitable material can be replaced; 2.Secondly, it is necessary to determine whether the tool for packing the box is perfect, and if it is not perfect, it can be replaced with a more perfect tool; 3.

Finally, to determine whether the method of packing the box is correct, if not, you can refer to some correct ways of packing the box, such as placing the box on a flat surface, fixing the edge of the box with a screwdriver, then taping the edge of the box up, and finally fixing the top of the box with tape. The above are the solutions and practical steps for the problem of packing boxes, I hope it can help you.

The speaker is no problem to listen to the monomer, but it is not good to pack the box.

In response to this problem, it may be that there is a problem when packing the box, it may be that the method of packing the box is incorrect, or the material of the box is not suitable, or the tool for packing the box is not perfect. Workaround:1

The above is the solution and practice of the problem of packing the box, I hope it can help you.

Can you tell us more about that?

The failure to pack the box may be due to the quality of the horn monomer, or due to the quality of the box. First of all, the quality of the horn monomers may not be good enough for them to fit properly in the box, resulting in poor case packing. Secondly, the quality of the box may not be good enough, and the structure of the box is not stable enough to bear the weight of the horn monomer, resulting in the inability to pack the box.

Therefore, in order to solve the problem of not being able to pack boxes, we must first check the quality of the speaker monomers to ensure that their quality meets the requirements and can be correctly installed in the box. Secondly, it is necessary to check the quality of the box to ensure that the structure of the box is stable and can bear the weight of the horn monomer. In addition, in the process of packing the box, the trembling branch should also pay attention to the installation of the speaker monomer to ensure that they can be correctly installed in the box, as well as the installation method of the box, to ensure that the structure of the box is stable and can bear the weight of the horn monomer.

Only in this way can the quality of the box be guaranteed and thus the best sound effect can be achieved.

The speaker is no problem to listen to the monomer, but it is not good to pack the box.

This situation is generally caused by the design and debugging of the speaker box. The single speaker has its own unique characteristics in terms of acoustic characteristics, and packing needs to consider factors such as cabinet material, size, shape, and airtightness to achieve the ideal acoustic effect. If the packing design is not reasonable, it can lead to the following problems:

The size of the cabinet is not suitable for the vibrillator: if the cabinet is too small or too large, it will affect the frequency response, sound pressure level and other acoustic characteristics of the speaker, and affect the sound quality performance. The shape of the box is not suitable:

The shape of the cabinet has a great influence on the acoustic characteristics of the speaker, and if the shape of the cabinet is not suitable, Binai will affect the frequency response of the speaker, sound pressure level and other acoustic characteristics. Inappropriate cabinet tightness: The different airtightness of the cabinet will affect the low-frequency response of the speaker, and if the airtightness is not suitable, it will affect the sound quality performance.

Therefore, if the monomer horn behaves normally when in use, but there is a problem after packing, it is necessary to check whether the design and debugging of the cabinet are reasonable. If you can't judge and solve it yourself, you can find a professional audio technician for testing and debugging.

According to your description: the string of condensers should be medium and low speakers, the string of inductors should be tweeters, and the 10-inch ones should be woofers.

Does the landlord want to DIY the speaker himself or just identify the speaker?

According to what you said, it should be a three-way speaker with treble + midrange + bass, the string of condensers is treble, the string of no components is bass, and the other is midrange.

If you need your own DIY speaker, the selection of speakers, the calculation and design of the cabinet, and the selection and debugging of the crossover all require a lot of experience. It is recommended to refer to the books of the People's Posts and Telecommunications Publishing House, "400 Cases of Amateur Design and Production of Speakers" and "20 Cases of Classic Speaker Production", or directly choose some DIY kits from large manufacturers, Huiwei has similar products.

For the tweeter, because the back of the speaker is a closed structure, and the wavelength of the high-frequency signal is short, it generally does not have an impact on the sound quality, but for the medium and low frequency speaker, because the back of the paper cone is open, the speaker is not loaded into the speaker, ** when the medium and low frequency audio signal is generated, the sound short circuit phenomenon will occur, so that the frequency response is narrowed, especially the low frequency signal loss is large.

The woofer must be equipped with a speaker to have a bass!

Mid-to-high speakers don't have this problem.

The bigger the woofer installation, the better the bass dive! The same inch speaker, the installation of the bookshelf box is not as good as the floor speaker bass!

And speakers below eight inches, it is best to do two-way frequency; Because the more crossovers, the greater the phase distortion! (Rookies don't understand and think that three-way frequency is good).

Only speakers of more than 10 inches are used as three-way speakers.
