What Is Tweeter? All You Need To Know Is Here!

What is tweeter? What are the main functions of this equipment? If you are curious about it, let’s read the article below to get a detailed explanation!

When you purchase electronic devices like a soundbar or set up a home theater system, you may hear “tweeter”. So, what is tweeter? What can it do for you? 

If you are curious about the equipment, let’s refer to the article below. It will address your concerns related to the tweeter. Click on it to get more detail!

What Is Tweeter? 

A tweeter is an electromechanical loudspeaker driver which acts as a transducer to reproduce music and sound in a higher frequency at around 2000 to beyond 20,000 Hz. 

In other words, it transforms sounds or electrical energy you hear from devices into soundwaves and then drives it to your eardrums in the upper music range.

In terms of construction, most of them comprise basic components such as magnet, cone, coil, spider, terminals, and tensile leads. When this device works, it moves the cone through the coil. After being charged, the electromagnet can move the cone. 

The purpose of the spider, which is between the cone and the magnet, is to provide suspension. The materials used for these pieces of equipment vary greatly, but they have the same basic functions. 

How does it work? It provides a sound range that normal speakers can’t typically perform. It connects with existing speakers to generate high-frequency trebles or sounds for higher effect and quality. 

The reason for this combination is because of some limitations in both speakers. In particular, normal speakers can’t generate higher-frequency sounds while tweeters can’t create lower-frequency sounds. 

Therefore, they work together to produce clear, high-quality sound ranges with frequencies that match your eardrums.

What Are Tweeter Main Functions?

At this point, you may imagine the general function of this audio device, which is to unite with other speakers to generate high-frequency sound. Now, let’s delve into its specific functions. 

Music Reproduction 

Only a range of sounds cannot generate music. It needs the complicated cooperation of various characteristics such as frequencies, tones, voice, or instruments. 

In this case, tweeters are helpful for sound systems in presenting the comprehensive sound range as you can listen from an audio output device like the soundbar.

Stereo Imaging

Music includes various sounds covering virtually all of the frequency ranges that human ears can hear. Moreover, it is usually recorded in stereo to reproduce the integrant studio instrumentation and sound location.

While recording music, musicians may use various instruments in different positions. Tweeters can represent how music is created, present spatial reminders, and give a cue for your brain which and where music comes from at higher-range frequency.

Car Tweeter

Apart from the above functions, it also acts as a part of a car speaker system rather than working alone to complement and harmonize with pre-existing components. 

A high-quality sound system in cars should include a woofer, passive crossovers, and a tweeter, separate from other elements. 

The midrange driver generates low to medium range frequencies with large sound waves but not pointing in one direction. So, the tweeter will make the sound pointed towards the listeners’ ears.

What Are Common Tweeter Types?

This device has a wide range of types, such as cone, dome, horn, or piezo. Two common types of which are cone tweeter and dome one. Let’s take a quick look at all of them.

A cone tweeter features an appearance of a standard loudspeaker. It is a paper speaker with a metal frame. However, it owns a thinner and lighter cone to move quickly and a more solid suspension to restrain sound flow at low frequency. 

On the other hand, the center of the dome tweeter is a small voice coil coated with a thin metal such as titanium or neodymium. This type is better in reproducing more accurate music and sound compared to the cone sort. That’s why it’s more costly. 

The treble frequency from this device is highly directional. That’s why people evaluate tweeters via the distribution characteristics, which refers to the extent of the distance they can efficiently spread.

In its simplest term, this is an off-axis rate response. People use a horn to unite some devices to direct sound reproduction in a specific area to make this response better. That’s the way horn tweeters are born. 

Another type is ribbon tweeter, which owns a lightweight and thin ribbon coil to deliver high-frequency sound as its name suggests. It requires more power than others to make the coil move quickly with higher dispersion charges.

Furthermore, this device includes an electrostatic kind, which has holes in the front and rear parts and uses electrostatic charges to cause the speaker to pulsate in time with the music.

Apart from these models, you can find an AMT tweeter in the market. It works by forcing air through a netting mesh, and high-quality, high-frequency sounds are generated in this way. 

There is a less common variety called the piezo. It doesn’t have magnets but works by curving piezo-electric electrostatic charges to respond to the applied voltage. This kind is more high-priced but less effective than the two above.

Each type has its unique properties. Thus, the best-suited one depends on personal taste and individual application. For instance, among them, horn and dome tweeters are more popular for home theatre systems.

The Bottom Line

The article has eventually addressed the commonly asked question: What is tweeter? In conclusion, it is an electromechanical transducer to deliver sounds in high frequencies and create good music. 

Besides, we have shared several tweeter types for you to consider if you tend to purchase one. Each has its unique features, so think about your personal use and preference before making a decision. 

Hopefully, you will find this post useful. Thanks for reading!
