Description

Earphone single structure

Technical Field

The utility model relates to the technical field of earphones, in particular to a single earphone structure.

Background

High-resolution headphones typically have a sophisticated driving monomer and optimized channel design that can exhibit a clear and vivid sound effect, providing rich detail and broad frequency response regardless of the type of music. The existing high-resolution earphone structure mainly comprises three types, namely a voice coil type earphone, a moving iron type earphone and a hybrid earphone, wherein:

The driving unit of voice coil earphone is composed of a coil and a permanent magnet, when the current passing through the coil is changed, it generates force in the magnetic field to make the coil move, and the vibrating diaphragm connected with the coil generates vibration to make sound.

The moving iron earphone is conducted to the center point of the miniature vibrating diaphragm through the connecting bar with precise structure, so that vibration is generated and sound is emitted, the moving iron earphone has the advantages of providing sound quality with more consistency and more strength, being warmer and thicker, playing details better, enabling lines of sound to feel clearer, and being suitable for listening to the types of music such as human sound, classical and the like which need to have richer and finer sound expression.

The hybrid earphone combines the technology of moving coil and moving iron, the moving coil unit is generally responsible for low frequency, the moving iron unit is generally responsible for medium and high frequency, and the hybrid earphone has the advantages and performances of moving coil and moving iron at the same time, and provides more comprehensive sound experience.

However, in practical use, the disadvantage of the hybrid earphone often occurs that three frequencies interfere with each other. Disadvantages of moving iron headphones include a narrower frequency response, possibly less natural sound, and typically poor performance, particularly at low frequencies. The voice coil earphone has the defects of complex structure, improved power use, increased noise, easy interaction interference and the like.

In particular, the conventional voice coil type has a circular structure and no package on the outer surface, and is difficult to be mounted in the inside technology of the in-ear earphone with limited space like high fax sound matching and combination, so that further improvement is necessary.
