Description

Head-mounted radiation-proof earphone

Technical Field

The utility model relates to an earphone field specifically is a wear-type radiation protection earphone.

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 advantage is that the user can listen to the sound independently without influencing other people; can also isolate the sound of the surrounding environment, and is very helpful for people who use in noisy environment such as a recording studio, a bar, a journey, sports, and the like. The earphone is originally used for telephones and radios, but with the prevalence of portable electronic devices, the earphone is mostly used for mobile phones, walkmans, radios, portable electronic games, digital audio players, and the like; earphones are classified according to the type of their driver (transducer) and the way they are worn.

The most common and common earphone is a moving-coil earphone, and its driving unit is basically a small moving-coil loudspeaker, which is driven by a voice coil in a permanent magnetic field to vibrate a diaphragm connected to the voice coil. The moving-coil earphone has high efficiency, can be mostly used as the earphone output drive of a sound device, and is reliable and durable. Generally speaking, the larger the diameter of the driving unit is, the more excellent the performance of the earphone is, and at present, the maximum diameter of the driving unit in consumer-grade earphones is 70mm, and generally, the driving unit is a flagship-grade earmuff earphone.

The earphone is conducted to the central point of a miniature diaphragm through a connecting rod with a precise structure, so that vibration and sound are generated. The moving-iron earphone can be easily placed in the ear canal because the unit volume is much smaller. This effectively reduces the area of the in-ear portion to fit into the deeper ear canal portion. The geometric structure of the auditory canal is much simpler than that of the auricle, and the ear canal belongs to a similar circle, so that a silica gel sleeve with soft texture can play a good sound insulation and sound leakage prevention effect compared with the traditional earplug.

The moving-iron earphone is an earphone with a moving-coil moving-iron mixed drive sounding function and has a structure of a single moving coil and a single moving iron, and a structure of a single moving coil and a structure of a double moving iron. The low frequency and the intermediate frequency are naturally presented by the moving coil unit, and the advantages of the low submergence depth and the clear intermediate frequency and natural transition of the moving coil are exerted. The moving iron unit has the advantages and the functions of mainly receiving and complementing the high-frequency attenuation section of the moving coil, starting from a frequency dividing point of 6kHz, and is responsible for high frequency to extend the high-frequency range to 30 kHz.

The driver of magnetic earphones such as earphone pictures is similar to a reduced planar speaker, and a planar voice coil is embedded in a light and thin diaphragm, so that driving force can be evenly distributed like a printed circuit board. The magnet is concentrated on one or both sides of the diaphragm (push-pull type), which vibrates in the magnetic field it forms. The equal-magnet earphone diaphragm is not as light as a static earphone diaphragm, but has the same large vibration area and similar tone quality, and is not as high in efficiency as a moving-coil earphone and not easy to drive.

The electrostatic earphone has a light and thin diaphragm polarized by a high dc voltage, and the electric energy required for polarization is converted from ac power, and also battery powered. The vibrating diaphragm is suspended in an electrostatic field formed by two fixed metal plates (stators), the electrostatic earphone must use a special amplifier to convert an audio signal into a voltage signal of hundreds of volts for driving, the sound pressure level which can be reached is not as large as that of a moving-coil earphone, but the response speed of the electrostatic earphone is high, various tiny details can be replayed, and the distortion is extremely low.

The electret earphone is also called a fixed type electrostatic earphone, the vibrating diaphragm of the electret earphone is polarized or polarized by an electrostatic field emitted by a polarized substance outside the vibrating diaphragm, and special equipment is not needed for providing a polarization voltage. The electret earphone has most characteristics of the electrostatic earphone, but the electret gradually depolarizes and needs to be replaced, and the service life of the electret earphone is about 5-10 years.

They consist of two parts, a signal transmitter and an earphone (usually of the moving coil type) with signal receiving and amplifying means. The emitter is connected with the signal source, and a front stage or an earphone amplifier can be connected in front of the emitter to improve the tone quality and adjust the tone color.

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 a few KHz to a few MHz, the effective distance is about 10 meters, and the earphone is within a visible range; the working frequency of the wireless earphone is VHF 130MHz-200 MHz, UHF 450MHz-900MHz, most of the wireless earphones work at UHF, the transmission range can reach 100 meters, and the wireless earphone 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.

However, when different types of earphones are used for sounding, the sounding part can stimulate the eardrum, so that the earphone has larger radiation, can cause eardrum damage after being used for a long time, and does not have a protection effect.
