What is the headphones and how to use them?

With the word “headphones” people can appear a variety of visual images. Because it is very important to know what the headphones are actually how they are arranged. It is also useful to find out how to use them to extend their service life and get real sound pleasure.

What it is?

If you contact the definition of headphones, it is not difficult to detect that they are usually associated with “headphones”. Such is the interpretation of such a term in most dictionaries and encyclopedia. But in practice, the headphones look very diverse, and sometimes it is difficult to even guess what the function of this subject. In general, it can be noted that these Devices are capable of translating a signal to a sound form that distribute various radio-electronic devices.

The specifics of the task is directly affected by the geometric shape of the design and on its practical parameters.

For what is needed?

Such devices allow you to listen to music, radio broadcasting or other broadcast (recording) without inconvenience for people around. Right serve headphones and those who go to distant distances. Traveling a passenger in the train and a long-distance bus, on a personal car very tiring and monotonous. The ability to relax and take time without interfering with anyone is also very valuable.

Even use headphones:

  • while waiting in various public and government agencies;
  • in sports training on the street and indoors;
  • To talk on the phone in headset mode;
  • To control the quality of audio records in the process of obtaining it;
  • for video broadcasts;
  • In a number of professional spheres (dispatchers, employees of call-centers, hot lines, secretaries, translators, journalists).

Device and principle of operation

The building of the headphones is different even in wired and wireless models. This is due to the fact that “inside” their main principle of operation is always the same. An important part of wired headphones is their speaker, the main component of which is the case. In the back of the dynamics housing there is a permanent magnet. The magnitude of the magnet is insignificant, but without it the normal operation of the device is impossible.

The middle part of the dynamics occupies a disc, which is usually made of plastics. Disc-shaped element joins a metal coil. Front block, directly distributing sound, contains holes for its free passage. Speakers in wired headphones are associated with a special wire. When the electric current comes in a speaker, the coil gets the charge and changes its polarity.

In this situation, the coil and magnet begin to interact. Their movement deform plastic disk. It is from this detail, or rather, from the features of its short-term deformation, the heated sound depends. Technology worked quite well, and even the cheapest headphones can exceed a variety of acoustic signals. Yes, music lovers can be opposed, but the sound is in any case it is recognizable.

    A little differently arranged wireless headphones.

      It is believed that they cannot give the highest quality sound. Therefore, only wired vehicles use in studio purposes. In most cases, the signal transmission is performed via Bluetooth protocol, but also use:

      • infrared range;
      • Wi-Fi;
      • Normal radio band.

      By destination

      In this regard, there are two main types of headphones – for studios and for private use. Monitor devices are distinguished by very high technical specifications. They can transmit the sound very clean and create a minimum of distortion. And according to a number of specialists, they do not distort anything when transmitted. Of course, for such perfection has to pay serious money. In everyday life, consumer-class headphones are more often used. Depending on the priority designers chosen by designers, they are best played:

      • lower;
      • medium;
      • high frequencies.

      According to the signal transmission method

      It’s mostly about the already mentioned Differences between wired and wireless devices. In the first case, the connection is performed using a special shielded cable. The quality of this screen determines how great the level of distortion and pressing will be. To remove the sound from the device, the Jack Standard Connector applies. Its size can be 2.5, 3.5 (most often) or 6.3 mm.

      But wireless headphones, as already mentioned, are divided into different types. Infrared devices appeared earlier than other options. This solution is inexpensive. An important advantage can also be considered absolute immunity to interference in the radio parasone. However, these advantages are pretty darken with such facts as:

      • disappearance of the signal even when a very weak barrier appears;
      • creation of interference with straight solar rays and any sources of heat;
      • limited range (not exceeding 6 m even in ideal conditions).

        Radio handsets operate in the range from 0.8 to 2.4 GHz. In them You can easily move almost any room. Even rather thick walls and entrance doors do not become a significant obstacle. However, the likelihood of encountered with interference is very large, they are quite difficult to cut off.

        In addition, the traditional radio is inferior to Bluetooth and Wi-Fi, spending much more current.

        By the number of channels

        When describing headphones, manufacturers necessarily focus on exactly the number of channels, it is Sound scheme. The cheapest devices are monophonic – allow you to use exactly one channel. Even unassuming consumers prefer stereo two-channel devices. Version 2.1 differs only by the presence of an additional low-frequency channel. To configure home theaters use headphones 5.1 or 7.one.

        By type of construction

        Frequently used enough Intracinal models. They are introduced inside the hearing canal. Despite the seeming simplicity and increased sound quality, such a performance is very harmful to health. Inserts or plug-in headphones are located inside the ear shell, but do not penetrate the ear and may even be away from it. As for the overhead option, everything is obvious – the device is located above the ear, and therefore the sound will go from top to bottom.

        Many people prefer Full-sized headphones. Actively uses them and professionals who need such equipment for full-fledged work. In the modifications of a closed type, incoming sounds do not pass at all. Open execution allows, thanks to special holes, control what is happening around. Of course, it is the second option that is preferable for movement along the modern city, saturated with cars and motorcycles.

        By type of fastening

        High-class headphones are usually equipped with headband. A similar arrow connects the cups themselves. Landing height can be adjusted in almost every model. Some main connecting element is located on the back of the head. There are still clips, that is, the mount directly on the ear shell, and the devices without fastening (inserted into the ear or in the auditory pass).

        By the method of connecting the cable

        IN bilateral version The wire feeding is connected to each speaker separately. One-sided scheme It implies that the sound is supplied first into one of the cups. His transfer to the slave cup occurs already with a different wire. The removal is most often hiding inside the arms.

        But the difference can concern and execute the connector. Traditionally, headphones are trying to equip with pin type minijack. Such a plug can be inserted into a cheap phone, both in an advanced smartphone, and a computer, TV, home theater column. But just jack (6.3 mm) and Microjack (2.5 mm) can only be used in conjunction with a special adapter (with rare exception).

        And the newest headphones are equipped with USB connectors, which are especially appreciated by lovers to communicate on Skype.

        By the design of the emitter

        Most modern models are used Electrodynamic method for obtaining sound. Structures inaccessible to the owner without the use of special tools contain membrane. The coil connected to the wire is supplied to it. When an alternating current acts onto the coil, the magnet produces a magnetic field. It has an impact on the membrane.

        Often engineers state that the dynamic scheme is outdated. However, the latest improvements have significantly improved sound quality even in such devices. High-quality alternative turn out to be Electrostatic, or otherwise electret, headphones. But it is impossible to buy such a device in the electronics supermarket, because it refers to the category Hi-End. The minimum price of electre headphones begins from $ 2,500.

        What is the headphones and how to use them?

        What is the headphones and how to use them?

        They work at the expense of a very thin membrane, which is precisely between the pair of electrodes. When they are fed to them, the membrane moves. It is its movement and turns out to be the source of acoustic oscillations. The electrostatic scheme is considered optimal because it creates sound almost without deviations from living sound. But at the same time, a large-sized amplifier must be used.

        From the mid-1970s produced Isodynamic headphones based on Haile emitter. Inside them there is a membrane in the form of a rectangle, which is made from thin teflon (actually films) coated with aluminum. For greater practicality, teflon is cut into rectangular strips. So sophisticatedly executed block is located between a pair of strong electromagnets. Under the action of the current plate begins to move, creating acoustic oscillations.

        Isodynamic headphones are valued for High reproduction accuracy (realistic sound). This solution also allows you to achieve a solid power supply, which is very relevant in loudspeakers. Hayila emitters can be performed by orthodynamic scheme. The only nuance is that the membrane will have a round shape.

        Still deserve attention reinforcement headphones. They are used exclusively in internally. A feature of the reinforcement headphones is the presence of a magnetic pipeline in the form of the letter. Magnetic field created by them affects anchor connected to a sound coil. Diffuser is attached directly to the anchor.

        When the current is received on the audio coil, the anchor is activated and moved the diffuser.

        By resistance

        The level of electrical resistance of headphones directly affects their volume. Usually adopted for simplicity impedance unchanged under all normal conditions, regardless of sound frequencies. Resistance to serialized headphones varies from 8 to 600 ohms. However, the most common “liners” impedance is not lower than 16 and no more than 64 ohms. Most often it is recommended for listening to sound from a smartphone to use headphones for 16-32 ohms, and for stationary audio equipment you need to use devices per 100 ohms and more.

        Best manufacturers

        Many people prefer headphones Beats. Especially appreciate their lovers of low-frequency sound. It should be borne in mind that the firm promotes his goods thanks to marketing and attract celebrities from the world of music. She does not lead engineering developments and does not have a separate production base. Therefore, to trust with such products – to solve only consumers themselves.

        A vivid example of quality products – Acoustics shure. True, this brand is mainly associated with microphones. But all the headphones of its production are distinguished by excellent quality. Most often they occupy an average and high price range. Sound in SHURE speakers is always highlighted by a smooth “natural” timbre, which is characteristic even for relatively budget versions.

        However, if it is decided to purchase a budget model, then you should look at the products Panasonic. All of them go out Under the technics brand. Such devices do not boast of special brand sound. But they definitely give out abundant bass. Technics from the Japanese giant recommend connoisseurs of rhythmic music of modern genres.

        No less good reputation managed to conquer in Xiaomi. Their headphones can consistently issue sound for a long time. At the same time, they still remain in a purely budget niche. Inwer the price firm is not in a hurry, although it introduces individual innovations.

        You can buy both intracanal and volumetric, both wired and bluetooth models.

        Lovers of truly elite products worth paying attention to Headphones Sennheiser. The German company traditionally works “at the highest category”. Even its budget models are advantageous from the products of competitors in the same price range. They invariably contain the latest technological developments. After all, Sennheiser attracts many world-class engineers, and it allows you to constantly go ahead.

        Most experts and experts, however, believe that it is much better to choose the product for a mass consumer Sony. This company consistently cares about the introduction of technological innovations. Of course, at the same time she constantly monitors the quality and durability of each development. Traditional for Sony Sound Oriented High Frequencies. However, this is a typical feature of any Japanese developments; but you can also purchase and full-sized, and overhead, and reinforcement, and all other types of headphones.

        Among rarely mentioned brands should be called KOSS. These American headphones will definitely not surprise a sophisticated design. But they are very durable, and therefore they can be considered a good investment of funds. Designers constantly pay attention to their mechanical strength and convenience. Melomanany with experience noted the particularly accurate transmission of sound.

        But the products of Russian firms are increasingly falling among excellent high-level headphones. A bright example – Fischer Audio. For a long time she was engaged in producing only inexpensive products, which, however, made it possible to conquer the audience and expand authority among consumers. Now the company can boast a unique sound of each advanced model and a special corporate philosophy. It is worth noting that the positive assessments of Fischer Audio products give even experts of the first magnitude of foreign countries, and a noticeable part of the products goes to export.

        In the Hi-Fi segment, it is worth noting the products Myst. This relatively small firm produces isoodinan headphones Izoem. Externally, they are similar to the early Sony models and have a kerch-shaped case. Like the previous models of the same manufacturer, this development has a cable in a rigid braid.

        The manufacturer notes that the headphones will “play” from the Hi-Fi serial player, and they do not need a stationary amplifier.

        How to choose?

        Evaluating the main technical characteristics of the headphones, it is necessary to pay attention to what their execution. Closed type will allow listening to music or radio, not disturbing surrounding people. Open devices Create inconvenience for them, but if it is not too significant in some situation, it will be possible to estimate more transparent sound. Such products are intended mainly for solitary listening.

        Full-size headphones are most often used for long music playback sessions.

        Overhead execution will inevitably put pressure on ear shell. However, for an athlete or DJ, it is almost the perfect option. Ahh (amplitude-frequency characteristic) shows the amplitude ratio and sound frequency. This parameter is strictly individual depends on physiological, psychological nuances and specific situations. Therefore, you can be guided by reviews and descriptions of specialists in order to cut off knowingly poor-quality goods. The final choice will have to do, listening to the game of headphones yourself and giving her own estimate.

        But even if the acoustic device is selected as it should, it will need to be used as little as possible. Both wired and wireless devices will have to be protected from water and systematically clean. Headphones with a Bluetooth module usually have a special switch (key) to start it. The operation of the device is indicated by the color indicator. Only by readiness for receiving makes sense to include the transfer of momentum from a smartphone or other device.

        Next, they choose among the general list those connections that need. In many cases Required password. If the usual option (4 units or 4 zero) does not work, you will have to get acquainted with the technical documentation. In some cases, it is possible to automatically pair “one button”, but it also sometimes has to configure. When using an external or built-in module, you can also transmit sound from a PC or laptop.

        Before using the buttons It is advisable to see in the instructions, what they know. This will avoid many unpleasant situations. It is not recommended to leave wireless headphones on recharging too long. Wired devices will work normally if the cable is not twisted and does not bend.

        Such recommendations are most often enough for the device for several years.
