Characteristics of moving coil, moving iron and ring iron earphone

Characteristics of moving coil, moving iron and ring iron earphone shared by Bluetooth Earphone supplier.

Moving coil headphones:

Moving coil earphones are divided into open, semi-open and enclosed earphones according to the degree of openness. At present, most earbuds are moving-coil earphones.

The principle is similar to that of ordinary loudspeaker. The coil in the permanent magnet field is connected to the diaphragm, and the coil drives the diaphragm to produce sound driven by the signal current.

Moving iron headphones:

Moving iron earphone is a kind of earphone that conducts to the center point of a miniature diaphragm through a precise connecting rod to produce vibration and sound.

Moving iron headphones can be easily inserted into the ear canal because the unit is much smaller. This effectively reduces the area of the inlet ear

You can put in a deeper part of the ear canal. The geometric structure of the ear canal is much simpler than that of the auricle. It belongs to the category of circle, so it is a soft silicone sleeve

Compared with traditional earplugs, earplugs have been able to provide sound insulation and sound leakage prevention.

Circle of iron headphones:

[Stereo neckband earbuds supplier]What is multi-channel 3d stereo?

What is multi-channel 3d stereo?

Multi-channel three dimensional stereo:

Stereo neckband earbuds supplier shares that earphone is a kind of electro-acoustic conversion device, which converts the electrical signal of sound into sound. There are two - channel and multi - channel systems in the existing technology.

But they unfold on a line or a plane, and a full stereo system should be a surround sound system that includes three dimensions. At this time, four speakers should be located in the four directions of the sound chamber. Four microphones of the same model with the characteristic of square root pointing can be used to pick up 3d stereo. It costs more to acquire 3d surround sound by using four-channel stereo system, so in practice, the two-channel stereo is often processed to produce simulated surround sound field. The special design of this patented product makes it superior in use and wide in application, and such products will be more widely concerned after they are launched into the market.

However, although there are various defects in traditional earphones, they still pose some competition to patented products due to their long time in the market. Generally speaking, the competitive environment of the market can be divided into four forms, namely, perfect monopoly, oligopoly, monopoly competition and perfect competition. According to the characteristics of the market, the market belongs to monopolistic competition market. Moreover, with the increase of the market share of this patent product, the corresponding similar products and imitations will also appear, and the trend of monopolistic competition will become more and more obvious.

THX and dolby digital and DTS technology, these technologies can be called a standard surround sound technology, of course, they are admittedly is currently the best surround sound technology, but also to have certain restrictions on applications, such as the equipment is expensive, strict listening environment, will have plenty of software, and people in certain time and certain conditions or restrictions to realize economic conditions.

This 3d stereo headset can be used with a computer, VCD, DVD and other stereo equipment can also be used (also can be used with VCD, DVD and other stereo equipment). It can be used to listen to the existing surround sound system, and can also develop the four-channel three-dimensional stereo system, the technical difficulty of this system is much lower than that of surround sound technology, and only needs twice as much as the two-channel system. Computer sound card, DVD, VCD chip processing technology will also be changed. This system may be the ultimate development trend of stereo system, which will replace the existing single, double and surround sound stereo system. In general, this patented product can be used to listen to existing surround sound directly on the market.

The development trend of headphone

Neckband Bluetooth Headset supplier would like to share the development trend of headphone for us.

Medical and productivity research has shown that in most common office Settings, constant and frequent phone calls can take a toll on workers' health and reduce productivity, especially if people are accustomed to holding the phone receiver between their head and shoulders to free up their hands to continue processing.

The use of earphones in the office goes back to before the advent of program-controlled automatic switches, when all phones had to be manually transferred and operators used cables to plug physical lines into a switchboard. Earphones freed up operators' hands. Modern office headset generally must have the following characteristics:

Mobility: the extent to which a user is allowed to move without interfering with a normal call. Modern office wireless earphone system generally sets this index as between 10 meters and 100 meters, compared with the wired earphone with long wire, its advantages are incomparable by the latter.

Compatibility: a measure of the versatility of the device interface that allows the user to switch back and forth between devices other than the system. Such devices include phones, desktops or laptop computers.

Closed tone and tone adjustment function: the closed tone function refers to the function that users do not want the current callers to participate in or be informed when they encounter other people's business or communication during the call.

Choose the remote pick up machine components, you can realize the remote pick up phone.

Industrial wireless earphones

The specific application of industrial wireless earphones includes the following aspects: site construction, such as overhead lifting equipment, airline ground staff, auction industry, fire protection, oil exploration and production, and industrial large-scale equipment operation, training and other occasions.

These occasions generally have the following characteristics: there may be a certain degree of risk, or operational errors will bring unexpected consequences, the immediate grasp of information, noisy environment to avoid misunderstanding, and so on. The structure, material or circuit design of the earphone put forward a strong targeted requirements. In such environments as turbine engine test rooms, electric pumps, toxic environment, buildings with a large number of reinforced concrete structures that hinder normal communication, such as exchanges, etc.

Future trends of headphones(part 1)

Future trends of headphones

Trend report shared by the bluetooth 5.0 earbuds factory.

Bluetooth:

The first peripheral to use Bluetooth technology will be a wireless headset. According to Ericsson's schedule, the headset for the Ericsson T28 phone was introduced in July 2000. Nokia and Motorola waited until late 2000. By then, you can put your phone in your pocket by attaching a Bluetooth technology accessory and placing a headset in your ear, free your hands when talking, or even press a button on the headset to answer a call. And, thanks to Ericsson T28's voice recognition capabilities, you can make common calls simply by naming people. Another selling point: since Bluetooth headphones emit at a much lower range than regular cell phone headphones, manufacturers will have a chance to play up the health benefits.

But with its low-power, near-field wireless location, bluetooth still has a lot of room for future consumer electronics. It will be the largest market for personal portable products such as mobile phones and pdas. By 2005, in-stat estimates that 71 percent of all bluetooth apps will be mobile, followed by 14 percent for personal computers and PC CARDS, and 6 percent for headsets. Analysts point out that with the development of bluetooth technology and the reduction of chipset costs, bluetooth and wi-fi will each account for half of the short-range wireless communication market.

Compared with special miniature invisible wireless earphones, civil and industrial wireless earphones are various. But there's not much special about earphones in terms of communication and electronics, and more in terms of acoustics.

The whole system can be analyzed with reference to the low power simplex or duplex radio communication system. Generally pay attention to restore the fidelity of sound quality, beautiful appearance, people love; In contrast, industrial wireless headsets are designed with more emphasis on reliability due to environmental reasons.

In the circuit, the higher level of products in the transmission process of processing, generally integrated with analog or digital compression technology, the use of modulation methods are also diverse such as RF RF, infrared, pure audio induction. For varieties adopting RF, products using ultra-high frequency band or bluetooth technology (900MHz-- 2.4ghz, etc.) can obtain more ideal technical indicators and meet the requirements of environmental protection, which actually represents an important development direction in this field.

As shown in the figure, this full-duplex wireless earphone for broadcast TV director adopts low-power FSK audio digital compression and decompression modulation processing technology, which has high restoration index and anti-interference performance in the range of 20Hz--20KHz audible audio. The overall work is at 863MHz in UHF band. PLL phase-locked loop makes it have stable rf performance, and the reliable communication distance in general environment is more than 150m.

Generally, to obtain a relatively ideal high speed digital transmission of speech compression effect, generally require larger RF bandwidth or advanced modulation technology, in order to reduce the transmission rate of digital voice signal, also often use adaptive audio pulse coding (ADPCM) or continuous variable slope delta modulation (CVSD) technology to the signal processing. These schemes are coded according to difference. The basic concept is to send the difference between current sampling and previous sampling instead of the absolute value obtained by sending samples.

Wireless earphones will be used in many occasions. In addition to radio and television systems, such as call center, audio-visual education, home HIFI, hands-free communication personal mobile phone (bluetooth earphone), "silent meeting", interview and investigation, tourism and other wireless earphone systems can show their charm, which is gradually becoming a trend. In fact, there is not much difference between the basic structure or circuit principle of various wireless headsets, and there is no need to divide them into strict categories. On the contrary, many earphones are used in a wide range of industries. When it comes to the differences, they are only applicable to different occasions at most. The system parameters and costs have certain preference, which is the same as the requirements of the special type of miniature wireless earphone system.

[In-ear headphones supplier]In-ear headphones with health

In-ear headphones with health

In-ear Metal Earbuds manufacturer shares that people often mistake the ingestive ear for hearing loss and ear disease. However, the truth is that in-ear headphones are very safe when used properly.

One: you need to know that no matter what kind of earphone (or speaker) you use, listening to music at a high volume for too long will damage your hearing. The advantage of in-ear headphones is that you can turn the volume down very low because you don't need to raise the volume to cancel out the background noise. This lower volume means that in noisy environments, in-ear earphones will be safer than non-in-ear earplugs. And do not think that the ear headphones close to the eardrum is easy to damage hearing. Since in-ear headphones are used at a lower volume, they are at least as safe as regular headphones at the same volume.

Number two: when something is inserted into your ear canal, your ear produces more wax. This is how the body protects itself against outside objects and prevents bacterial growth by keeping the ear canal moist and closed. Therefore, when using in-ear headphones, it's best to remove the headphones from time to time to allow air flow to relax the ear canal (and to give your middle/deep ear canal a short break from the constant bombardment of sound). Regular earwax cleaning is also recommended. However, before you do it yourself, consult your doctor about how to safely clean your earwax. When the wax accidentally enters the inner ear canal, it can become blocked and even contagious (if it hurts the eardrum). Stop using any earphones and seek medical attention immediately if an ear infection is found.

It is also important to note that humans do not adapt to long periods of noise, even at low sound pressures. A recent study by the world health organization found that low noise levels did not cause hearing loss, but still had a negative effect on the body. People exposed to noise for long periods of time are more likely to suffer from serious illnesses, both physically and mentally. Although I haven't studied hard, my advice is to think carefully before you listen to music for a long time, even at a low volume. We all love music, but that doesn't mean we should listen to it all the time.

In short, listen at a low volume, as needed, and keep your ear canal and in-ear headphones clean. Don't listen too long. Remember: the process of hearing loss is irreversible, so use this common sense to take care of yourself.

Share you the active noise reduction

As a Sports Wireless Headset manufacturer, today we would like to shares with you the active noise reduction.

1. What is active noise reduction?

Earphones, while they help insulate us from most of the noise in the environment, typically target high-frequency noise that doesn't penetrate through sound waves very well. However, in the bus, subway or office, there are more low-frequency noises that we cannot avoid, such as the sound of bus engine and air conditioner.

The noise lurking around us can subtly affect our work and life mood, and then cause a health crisis. This is where the active noise reduction features of the Toffee headphones come into play. The so-called active noise reduction is based on passive noise reduction to further filter out low-frequency noise in the environment and help users get rid of noise pollution completely.

2. How to actively reduce noise?

To actively reduce noise, Toffee also relies on the smart noise reduction chip in the headset to help. This chip can comprehensively analyze and process noise reduction signals, and simultaneously eliminate noise while collecting noise signals to the maximum. In addition, Toffee active noise reduction headphones also have high temperature qualitative noise reduction technology. So whether or not the user turns on active noise reduction, the technology will help maintain the headphone's tri-frequency balance and eliminate 85% of the ambient noise, leaving music intact.
