What is Mid Speaker? The use of the Mid speaker in the sound system and the difference between the frequency bands

In the audio system, each speaker line has its own function to help listeners enjoy music to the fullest. Let’s learn about Mid speaker and outstanding use of Mid speaker in sound system with Tnhelearning.edu.vn!

What is Mid Speaker? Structure of the Mid speaker

Mid speaker is an audio device operating from 500Hz to 6kHz frequency , with the function of processing input signals to output sound and transmit it to the listener’s ears.

In other words, the Mid speaker has a wide frequency range and can change sound levels quickly, from basic instrument sounds to animal sounds (like animal calls and voices). human), thereby helping the listener perceive the sound more pleasant.

The structure of the Mid speaker also has some similarities with the Bass and Treble speakers. As follows:

– Frame: Is the part that mounts many other parts and components of the speaker, which can be made from plastic, aluminum to iron. In general, the frame will not affect the sound quality much, but you should not choose a frame that is too large to cause direct reflection at the diaphragm.

– Shrink: Usually made of paper (or cloth) folded together with the diaphragm, which has the function of keeping air tight and creating flexibility for the speaker. If you are a person who is familiar with music, when looking at this part, you will know the sound characteristics of the speaker.

– Spider web: Shaped like a spring in a driver with the main function of receiving and transmitting signals, the quality of this part also contributes to the overall sound quality.

– Magnets: Composed of quite complex with 3 popular types: Neodymium, Ferrite and Alnico. In particular, Neodymium magnets are most commonly used with moderate prices.

– Copper coil: Consisting of a cylindrical core and wrapped with copper wire (can be coated with aluminum) around, it is placed in the magnetic gap. The smaller the gap, the higher the magnetic density, resulting in clearer loud sound quality.

In addition, the fact that the copper coil is wound many turns, even round or flat, affects many parameters of the sound, especially for low frequencies to pass through. While, the capacitor has the function of allowing high frequency to pass through.

It can be said that a capacitor connected in series with a copper coil will have the effect of limiting high and low frequencies entering the speaker, so it is often used for Mid speakers.

– Diaphragm: Made from many materials such as plastic, paper, metal, … and this is also one of the important parts of the speaker, because the vibration of the diaphragm greatly affects the sound output. In other words, whether the Mid speaker sounds bad or not thanks to the quality of the diaphragm.

Distinguish 3 audio frequency bands of Mid . speakers

Mid speaker works with a wide sound range, usually divided into 3 audio frequency bands as follows:

High Mid (High Mid)

High sound is considered the last sound range of the Mid speaker when it is necessary to process the input signal to bring the sound out, and then transmit it to the listener’s ears, operating mainly at the frequency of 2kHz – 6kHz .

For example, with songs with depth, high tones can be considered a decisive factor in the depth of each note as well as each word, thereby helping listeners feel the most authentic voice of the song. doctor.

Mid (Mid)

Mid-range is the medium frequency range, mainly from 1kHz – 2kHz , this is the frequency of sound commonly emitted in basic musical instruments and human voices.

The type of sound helps the music to re-balance between bass and treble, to support listeners to enjoy the song more fully and smoothly.

Low Mid (Low Mid)

Low tones are areas of sound frequencies ranging from 500Hz – 1kHz , commonly found in basic instruments such as pianos and guitars, or the sounds that come from the sound of animals.

To make it easier to imagine, you can come across a situation like watching a program on TV, in which there are so many sounds that you cannot hear the main speaker’s voice clearly.

At this point, you adjust the volume of the Treble speaker and the Bass speaker, which means increasing the volume of the Mid speaker to hear the voice more clearly.

The role of the Mid speaker in the sound system

Like the typical function of Bass and Treble speakers, Mid speakers also play a separate role in the sound system. As follows:

– Improves sound quality, helping you hear more clearly the sound quality (or voice) in music and musical instruments.

– If the Mid speaker is missing, the words, lyrics or the sound of the instrument are almost impossible to hear.

Because in an audio system, the Treble speaker is in charge of the treble (high tones), the Bass speaker is in charge of the bass to the subwoofer, these sounds are often not audible to our ears. Therefore, the Mid speaker has the effect of balancing the sound emitted by these two types of speakers, thereby helping you enjoy the sound more fully.

Difference between Mid speaker with Bass speaker and Treble speaker

Based on some characteristics, you can quickly distinguish between speakers such as Bass speakers, Treble speakers and Mid speakers together simply as follows:

Bass Speaker	Treble Speaker	Speaker Mid
Design style	The speaker construction is almost the same, but with a different number of inductors (copper coils) along with some components such as capacitors, to create a specific sound quality for each speaker.
Frame Diameter	Biggest	Smallest	Medium
Audio frequency range	20Hz – 500Hz	6kHz – 20kHz	500Hz – 6kHz
Diaphragm materials	Paper, plastic, metal…	Titanium, silk, aluminum…	Paper, plastic, metal…
Corresponding to the sound	Bass (bass)	Treble (Tribs, Highs)	Mid (midrange)
