What are the main factors that determine the sound quality of a good speaker?

We listen to audio equipment, of course, the most attention to its sound quality is good or bad. One author wrote about speaker speakers. The sound quality is most important. It doesn't matter what material the speaker diaphragm uses. There is no logical problem with this sentence, and the key lies in substance. This sentence seems to be the opposite, speaker diaphragm material is very important, diaphragm material plays a crucial role in speaker sound quality. Different Beats By Dre Cheap diaphragm materials determine the speaker's sound quality orientation or, in order to make the speaker's sound quality satisfactory, choose to use a new material. The choice and use of a new material often means a change to the speaker cabinet. In the early years, electrodynamic speakers basically used pulp diaphragms, when the speakers were called cone speakers. Polypropylene diaphragms (PP pots) emerged in the 1990s; the subsequent appearance of bulletproof fabrics (Kevlar fibers) gave a fresh sensation. The different timbres of Thiel, AE and other speakers have a great relationship with their use of metal diaphragms. In the audio industry, audio and music lovers, the term sound quality is almost like day-to-night. What is the sound quality? Like many everyday concepts, we rarely think about it, and we rarely go deep into it. As the name suggests, or literally meaning, sound quality is the quality of the sound. But what is the quality of the sound? How does the quality of the voice behave and how does it measure and evaluate it? Cheap Beats By Dr Dre Is there an objectively agreed standard?

The difference in the understanding of vocalization is even more subtle. We can distinguish between strangers and acquaintances, people who are familiar with them, and even those who have not seen them, such as hearing their voices. Footsteps, door slamming and coughing alone can accurately identify the arrival of acquaintances. The auditory impression corresponding to this distinction is called timbre. Each kind of sound has its own characteristics, and the sound has invisible and intangible mystery.

When evaluating sounds and describing sounds, there are often poor words. Therefore, we seek help from our daily experience. Since there are colorful paintings, we can have colorful sounds. In addition to color, we describe sound music and constantly use familiar everyday experiences. The sense of warmth describes the coldness and heat of the sound; the physical sense describes the soft, crisp, loose, and hard sound; the physical sense describes the thick, thin, narrow, and wide sound. The tone is related to the composition and time structure of the sound.

We may wish to inquire into the timbre of the timbre slightly from the physics. There are all kinds of voices in the world, and there are many kinds of musical instruments that are refurbished in various parts of the country. Naturally, their sounds are different. The timbre is also related to the composition of the sound. The sound component is simple, the purest is the pure tone, and the natural tone is very few. The pure tone of various frequencies can be emitted by an instrument such as an audio signal generator.

Recently, some magazines have recorded pure audio signals as CD-ROMs for the convenience of many readers who have no instruments. What does the 400Hz, 600Hz pure tone sound like? It really needs to be felt, especially for people who have never felt it before. The feeling of pure tone is "light" and "clear," and "light" is the lightness of the sky. "Qing" is the clearing of fish without water. The sound is thin, and it is not a sound composed of music and multiple components. The sound is full. All kinds of musical instruments (excluding electronic musical instruments) do not emit a single frequency, pure vibration of a single vibration. The sound of a musical instrument is generally made up of an integral multiple of harmonics of the pitch and pitch. Almost all sounds in the natural world are complex sounds, including harmonics and noises of different amplitude levels, which form different sounds.

The frequency spectrum of the flute shows fewer harmonics. The range of flute is still relatively narrow, about 600 ~ 6000Hz. Mozart had two flute concertos in close-up, showing the various timbres of the flute. Some people love to call the flute the "Flower Soprano" and show their love of the flute.

The spectrum of the violin, which includes many high-order harmonics, indicates that the timbre is plump and mellow. The tone of the string is extremely full and complex. People praised the famous pianos Stydalvavarie and Guadalajara 200 years ago, and even the violins made of the same shape, size, material, and craftsmanship are hard to come by. Experience tells us that it is difficult to find two identical people in the world. Finding two violins with exactly the same timbre is also quite difficult, not to mention the different performers playing skills and controlling the changes in the timbre.

There will also be some noise in the instrument. Like percussion instruments, noise plays an important role in the timbre. A hazy spectrum. Not only is there no integer relationship between the constituent tones, the timbre is cluttered and there are many noises. Even if it is a violin, the bow is pulled on four strings, and the bow is rosin-smelling. When the bow pulls the string, it not only sends out songs like v. dreamlike moving music. There will also be frictional noise. The higher the pull, the greater the noise. Some enthusiasts say they can hear the scent of the violin. No sound has yet been found to spread the scent. The beats by dre studio association caused by this friction noise is probably the pine scent that some of our enthusiasts can hear. In addition, the timbre is also related to the time structure, that is, there is a close relationship with the establishment and attenuation of the sound. Piano spectrum diagram shows. The sound of the piano starts with a strong press and then gradually decays. The organ is gradually increased in a short period of time to maintain a certain level of sound, and then quickly decay. This can also be called a sound pattern, an envelope.

The meaning of the above is summed up. The reason why there are different sensations is that, in terms of composition, each sound component is different. It will have many harmonics and noises; these harmonics and noises can have certain rules, or they can have no regular pattern. From the time structure is its shape is different, the diaphragm and the time are also different. beats by dre wireless This combination of changes is endless. A good speaker is to reproduce the sound characteristics of the music without distortion.
