There are several factors positively driving the earphone and headphone industry. Increasing popularity of OTT platforms and increased number of hours spent on watching OTT videos. Also, with the advent of spatial audio technologies, high definition quality, growing music industry, consumer preference is also observed towards advanced audio experience using earphones and headphones.
Earphones and Headphones are extensively being used for listening to music or while watching videos and playing video games. These are available in various sizes, shapes and colors. General public is showcasing more interest in advanced technology based devices such as earbuds or wireless headphones. Continuous Technological upgrades in the manufacturing of electronic devices is making an impact on production of earphones and headphones.
What Is An Earphone And Headphone?
The term earphone can be described as the form of transducer that has dispensed with the cushioning and consists of a small earpiece that fits into the ear itself. Earphones can easily be powered by mobile phones or other music player devices and are ideal for music on the go. There is a very wide variety of earphones available for purchase from the very low cost items, to those that are expensive, but produce very high quality audio.
Headphones themselves are essentially a pair of small speakers that are attached to a band that is positioned across the wearer’s head to enable the speakers to be positioned over the ears. Normally there are cushions that are placed around the speakers and over the ears for comfort and sound insulation. Headphone transducers do not need to move large volumes of air like speakers and therefore they can deliver a very impressive sound.Headphones are often used with higher end audio visual applications.
Technologies Used For Earphones And Headphones
There are several different technologies used for headphones and earphones to offer better and these technologies are as follows.
- Moving coil: It is the most widely used earphone technology. In this type, essentially a current is passed through a movable coil which is held in a static magnetic field. As current passes through the coil, forces are set up causing vibrations which are then passed to a diaphragm which is physically connected to the coil.
- Planar magnetic headphones & earphones: This type of headphone / earphone driver technology utilizes a thin diaphragm with an embedded conductor suspended between magnets either side. As the diaphragm can be made very thin, they respond very accurately to the sound signal passing through the conductor.
- Balanced armature: Balanced armature technology was initially developed for use with hearing aids. In this type, the headphone drivers are small making them ideal for hearing aids. However, they are also used for in-ear monitors.
- Piezoelectric earpiece: This type of earpiece technology is often known as a crystal earpiece because it uses a piezoelectric crystal to convert the electrical variations into sound.
Different Types of Earphones And Headphones
Some of the major types of earphone and headphone technology available in the market are as described below.
1. Wired Earphones
These are one of the most popular earphones. Wired earphones are inexpensive and provide comfort, sound isolation and sound accuracy.
2. (Earbuds) Wireless Earphones
Earbuds are very small in-ear earphones that can be connected to any device through bluetooth. These can fit your ear canal and are lightweight which makes them ideal for outdoor activity. Earbuds are battery powered and required to be charged timely.
3. Closed-back Headphones
Closed-back Headphones offer great noise canceling. Such headphones are very heavy and are generally used by musicians and singers. Closed-back headphones come In both on-ear and over-ear style.
4. Open-Back Headphones
open-back headphones have open ear cups that allow some sound to escape into the environment on purpose. This type of headphones are used for mixing and mastering sound in studio settings. Open-back headphones are great for sound isolation.
5. On-Ear Headphones
On-ear headphones are placed over the head and rest on top of the ears. It does not fully cover ear cups, so sound leakage is very normal. These types of headphones are lightweight and less in cost than over-ear or bluetooth headphones.
6. Over-Ear Headphones
The over-Ear headphones fit on the top of the head and cover the whole ear cup which reduces the air circulation in and out. These are great noise canceling headphones. It has cup cushioning of different materials to provide comfort to ears
7. Bluetooth Headphones
These are wireless headphones that have a small computer chip for connectivity via bluetooth. Bluetooth headphones transfer sound waves by air and to the receiver,and are ideal for an activity like sports, gyms, outdoor, or traveling.
Conclusively, With developments in mobile phones, tablets or laptops and advancements in audio technology, there will be a requirement of compatible earphones and headphones. This will help the earphone and headphone technology market to expand and launch more technically advanced customer pleasing products.
