Background

Earphones (ears; heads-sets; ears) are a pair of conversion units that receive electrical signals from a media player or receiver and convert them into audible sound waves using speakers near the ears. The headset is typically detachable from the media player and utilizes a plug connection. The advantages are that it can listen to the sound independently without affecting other people, and can isolate the sound of the surrounding environment, which is very helpful for the people who use in the noise environment such as recording room, pub, trip, sport, etc. The earphone is originally used for telephone and radio, but with the prevalence of portable electronic devices, the earphone is often used for mobile phones, walkmans, radios, portable electronic games, digital audio players, and the like.

From the development of the whole audio industry, the wireless headset still is a new thing, the development time is not long, at present, the user demand is continuously improved, the expected value of the wireless headset of the user is also improved, and the new examination is provided for the industry. At present, the most concerned key points of users comprise tone quality, cruising ability and wireless transmission ability, from the data point of view, the wireless transmission ability can basically meet the requirements of most users, and the tone quality and cruising ability have great promotion potential, and if the promotion is started from the two points, the user eyes can be easily attracted in the future.

The earphone is a symbol of a person's carry-on sound. The earphone of the mobile phone is divided into two standards, namely OMTP standard is generally called national standard, and CTIA is called international standard. The earphones are classified according to their transduction modes, mainly including a moving coil mode, a moving iron mode, an electrostatic mode, and an isomagnetic mode. The earphone is structurally classified into a semi-open type and a closed type according to functional modes, the earphone is classified into an ear plug type, a hanging ear type, an in-ear type and a head wearing type according to wearing modes, the single-person earphone and the multi-person earphone are classified according to wearing persons, the earphone is classified into an active earphone and a passive earphone according to sound sources, and the active earphone is also commonly called a card earphone.

A wireless headset generally refers to a headset system that transmits signals in infrared rays, and a cordless headset refers to a headset system that transmits signals using radio waves. The working frequency of the infrared earphone is from several KHz to several MHz, the effective distance is about 10 meters, the earphone is in a visible range, the working frequency of the radio earphone is VHF 130MHz-200 MHz and UHF 450 MHz-900 MHz, most of cordless earphones work in UHF, the transmittable range reaches 100 meters, and the wireless earphones can bypass obstacles. Two or more pairs of wireless/cordless headsets may interfere with each other, so it is preferable to select a variety of these with multiple operating frequencies, and for cordless headsets, less likely to interfere at UHF than VHF. Both of these earphones have background noise, and higher models have noise reduction techniques. It is also noted that the time of use of the wireless/cordless headset battery should not be below 8 hours in general.

The types of earphones are gradually enriched due to different purposes of the earphones. The types of earphones can be broadly classified into open type, closed type, and semi-open type.

The open type earphone generally has natural listening feeling and is comfortable to wear, the comfort is free from muggy feeling, and the open type earphone is a high fidelity (HIFI) earphone which is commonly enjoyed at home. The sound can be leaked out, otherwise external sound can also be heard, and the earphone is less in oppression sense to the ear.

The semi-open type earphone has no strict regulation, and the sound can only go in and out, and the design adjustment is made according to the use requirement.

The earmuffs of the closed earphone adopt a fully-closed structure, so that external sound can be prevented from entering, the oppression to ears is large, the sound positioning is accurate and clear, and the structure is adopted in the field of professional monitoring. And a partially enclosed earphone having the sound field of an open earphone, which can isolate noise and maintain high quality sound,

earphones have evolved to the present day, with the most prominent sound generation unit being the moving coil sound generation unit. Moving coil earphone technology has matured over the years, but it also encounters bottlenecks in sound enhancement. In addition to electrostatic earphones, moving coil sound units have many derivatives, the most widely used of which is moving iron sound unit.

The moving iron sounding unit utilizes the electromagnet to generate an alternating magnetic field, the vibrating part is that an iron sheet is suspended in front of the electromagnet, and the signal can change the magnetic field of the electromagnet when passing through the electromagnet, so that the iron sheet can vibrate and sound. Its advantages are long service life and high efficiency. The disadvantages are large distortion and narrow frequency response. Often used in early telephone handsets. The technology is mainly used for earplugs at present, because the moving iron sounding unit is much smaller than the moving coil sounding unit, two or even three moving iron sounding units are integrated in a plurality of high-grade earplugs, and the sound performance of each frequency band is very excellent.

The diaphragm is suspended in an electrostatic field formed by two fixed metal plates (stators), the electrostatic earphone must use a special amplifier to convert the audio signal into a voltage signal of hundreds of volts,

although the electrostatic earphone has various advantages, the technology of the sounding unit is only mastered by a few manufacturers, and the basic selling price of the electrostatic earphone on the market is more than ten thousand yuan. It is worth mentioning that China's earphone has fever friends, WINNY develops the first set of electrostatic earphones in China by itself, and becomes a milestone earphone in the development history of earphones in China.

The development of headphone presentations is towards wireless and noise reduction. The wireless earphone uses more freely, and along with the development of science and technology, wireless transmission technology is mature gradually, has guaranteed wireless earphone's tone quality. Another reason is the popularization of music functions of mobile phones and the emergence of bluetooth wireless transmission technology, and bluetooth wireless headsets are rapidly developing.

With the more serious noise pollution in cities, the common earphone earplugs used outdoors can only increase the volume to cover the noise, so that the common earphone earplugs cannot enjoy delicate music and have great influence on the hearing of the common earphone earplugs. The noise reduction earphone well solves the problem.

The active noise reduction earphone is provided with a noise reducer, wherein the noise reducer collects external sound by using a microphone and sends out opposite sound waves to play a role in counteracting noise. Nowadays, people are more and more concerned about their health, the earphone that makes an uproar falls can be better in the outdoor music of enjoying, can also guarantee the health of ear, is the development direction of future earphone. The active noise reduction earphone has an earphone specially designed for travelers, has the characteristics of wireless, noise reduction and high sound quality, and can provide music listening for 10 hours with the Bluetooth 3.0 of the aptX.

The scientific technology can only rely on radio signals to transmit information conveniently, so that the radiation of the mobile phone is inevitable. The mobile phone is a strong radiation source, particularly the power of the mobile phone at the moment of connection is amazing, and even people can die suddenly after receiving and making calls frequently for a long time. Since the intensity of radiation is inversely proportional to the square of the distance, maintaining the distance is most effective in applications where radiation from a handset is prevented. The basic principle of the radiation-proof earphone is to enlarge the distance between the brain and the mobile phone, and the radiation-proof earphone cannot really play a role in radiation protection.

There are two types of earphones which are used in the mobile phone on the market today and can be called as radiation-proof earphones, including a bluetooth earphone and an air conduction earphone, among which the air conduction earphone is more effective. An air conduction earphone developed by Chinese science and technology personnel obtains an invention patent of the world intellectual property organization International (PCT) (the patent international application number is PCT/CN2009/000660, and the international publication number is WO 2010/043097A 1).
