Different Earbud Driver Materials and their Impact on the Sound Quality



 If you are looking to purchase a perfect pair of earbuds that matches your needs and lifestyle, then you know should how they work. There is a lot more to it than just choosing the ones that attracts you with the looks at first. Earbuds — a small piece but there are many parts in the buds which make them different from each other. One of the most important features is the driver and you must know which driver you have to use.
A driver is usually made up of three components: the magnet, the diaphragm, voice coils. It converts electrical signals into sound for better and best clarity. Sound is produced when an electronic signal is passed through the magnet that created alternating magnetic fields forcing the coils to move up and down, this leads to generate sound waves. The quality of the sound is solely dependant on which type of driver you are using, the weight and strength of the diaphragm within the driver plays a crucial role for the high definition and clarity of the sound. Cheaper driver materials cannot withstand high power and they can easily break, always look for a strong and high-quality material to have a better listening experience.

Different Types of Earbud Drivers based on their Composition

Types of speaker driver units inside a headphone/earphone

There are four main types of drivers found inside the earbuds which are as follows:
1. Dynamic Driver Unit
2. Planar Magnetic Drivers
3. Electrostatic Driver Unit
4. Balanced Armature Unit
The drivers used in various earbuds are made of different materials like Graphene, Titanium, and Beryllium. They also have magnets made up of either neodymium or ferrite. Earphones can have driver sizes ranging from 7-15mm. Below are some of the earbud drivers with which most of the earbuds are equipped.

1. Graphene Drivers

Graphene is a form of carbon in a two-dimensional, one atom thick film. It is the basic structural element among other allotropes, including charcoal, graphite, and carbon nanotubes. Graphene is 200 times stronger than the high-strength (high-carbon) steel and it efficiently conducts heat and the electricity. Carbon materials usually have excellent acoustical properties. The graphene drivers are very thin and light and come with a small spring constant, so that the air itself damps the motion. The damped air in graphene converts almost all the energy into sound and is therefore potentially very efficient. Graphene diaphragm is very strong and thin and requires no or little external damping.
Graphene material is known for its highly conductive strong, and thin, and lightweight properties. Graphene is an ideal material for speaker diaphragms as it is amazingly strong and can be extremely thin and light weight. It is also relatively expensive. Graphene is stronger than steel and thinner than a paper and is best at electricity with the electrodes moving at a speed of 1/300 of lightspeed. The lightweight property allows it to move rapidly and act sensitively. The strong property of graphene keeps it unbreakable and unchangeable. A thin graphene of 100nm can bear a load of up to 2 tons. It can also hold its shape in motions and vibrations.

2. Titanium Drivers

Titanium is a transition metal of silver color with low density, and high strength. Titanium has the highest strength-to-weight ratio of any metal. It is applied to earbud drivers to make sure that they are as light and strong as possible. This means that the diaphragm in titanium driver earbuds is stiff and strong enough to resonate high-fidelity, clear sound and high quality throughout the audio spectrum, and at the same time light and precise enough to ensure super fast response times and the accurate reproduction of sounds.

3. Beryllium Drivers

Beryllium is an amazing material for drivers from the sound point of view. It is very lightweight but is very stiff, which means that it shows no break-up in the audible range of frequency. Beryllium drivers show very high internal damping which result in a linear and flat frequency response up to very high frequencies. It can minimize ringing distortion that is heard from the traditional metal diaphragms (like in titanium or aluminum). It is not commonly used as dust is created during its production and handling of the raw material which extremely toxic and can cause cancerous tumors and damage the skin, liver, lung, or spleen. It is not commonly used as it can be toxic and can harm human. This is not a problem for the consumer since it oxidises and forms a passive layer at the contact with air. However, there is no danger for the user, but it can be a problem during manufacturing as it needs great care on ventilation which can be very expensive.


Commonly Used Magnets in Earbud Drivers

There are different magnets used in earbuds like neodymium, ferrite, cobalt, and aluminium, etc. But the ones mostly used are Neodymium and Ferrite. Neodymium is better than Ferrite when it comes to the magnet used in the earbuds, so we have discussed it below. It is eight times better than a ferrite magnet.
Neodymium
Neodymium is a chemical element which belongs to the lanthanide series and is a rare-earth element. Neodymium driver earbuds feature a driver, it is the element that converts electrical signal into sound, which is made of a neodymium magnet. It provides a good bass response and higher overall sound quality. These neodymium magnets are better than other type of permanent magnets as they provide equal amount of magnetic strength that too in lesser size as compared to other type of magnets. These Neodymium magnet earbuds are eight times better than ferrite magnets. The retention capacity of these drivers’ magnetic field is much better than other conventional ferric magnets.
The magnetic field which is generated by these magnets is very less and is not harmful and does not threaten to human health.

 

Types of Drivers Used in Tranya Earbuds
Tranya makes sure to equip its earbuds with the best technology to ensure a sound experience for you that you will never forget. And for that, Tranya introduced Graphene and Titanium drivers in their earbuds for an amazing listening experience. Have a look at some of the earbud models and the type of drivers they are incorporated with.

1. Tranya T10
Tranya T10 is equipped with a 12mm graphene driver which is super light in weight and with the highest strength to weight ratio. The graphene driver generates a dynamic and responsive performance. The driver is the most important part in the earbuds as it is the unit that converts the electrical signals into sound. The sound we hear from the headphones is produced by the driver. The larger the driver, the better the bass. T10 earbuds are equipped with 12mm Graphene Driver which creates a dynamic and responsive performance. Sound is produced as it is in original with this advanced 12mm driver.

2. Tranya B530 Pro
Tranya B530 provides you an HD sound experience with their Titanium Dynamic Drivers. This pair is specially structured to be a perfect combination for a music lover who loves to feel the deep bass. With the help of low sub bass resonance at 20Hz to 80Hz, you can listen to the rich dynamic sound.

3. Tranya Rimor
Tranya Rimor ensures Hi-Fidelity stereo audio with amazing clarity and spaciousness. Rimor has a 10mm dynamic titanium driver which reproduces a wide frequency range of 20 to 20,000 Hz delivering the crystal-clear treble and lets you enjoy the original sound with details 3 times better than any other typical earbuds with a 6mm driver. This 10mm driver is very strong and delivers a crystal clear, hi-fidelity and original sound, accurately and ultra-fast.

Bottomline
Before buying the earbuds, you must have knowledge about the driver and the material used. Choose the one which best suit you and is under your budget. The best drivers are the ones made of graphene or titanium having neodymium magnet. The size of the driver is also very important. Large driver can provide you with a better HD sound experience. But always keep in mind, that not every large driver provides the best sound, some claim that they have large drivers but when it comes to the sound quality, it is not up to the mark. Tranya offers earbuds with the best features in an affordable price. So before purchasing, always check out the features.
