Earphone

Abstract

The invention relates to an earphone, comprising a voice coil, a vibrating diaphragm and a dustproof cover; wherein the voice coil is wound by voice coil wires; the output end of the voice coil wire is connected with a wire; one end of the wire hangs in the air; the wire comprises a bending segment which consists of a folded line unit and / or a bent line unit in the same plane; and the range of the bent line is gradually descended. The folded line unit is formed by straight wires in a certain angle; the bent line unit is formed by bent wires in a certain radian; the width between the straight wires of the folded line unit and / or the width between the bent wires of the bent line unit are gradually descended from the output end of the voice coil wire to the wire hanging end containing the bent line. The wire eliminates harmonic waves and ensures the acoustics of the regenerated sound of the earphone. Furthermore, the projection of the dustproof cover on the bottom of the vibrating diaphragm is positioned in a triangular that is formed by the projection of a first through hole of alt register, a second through hole of a mediant register and a third through hole of a bourdon register arranged on the vibrating diaphragm in a plane where the bottom of the vibrating film is positioned; the earphone overcomes asynchronous transmission of alt, mediant and bourdon and ensures the full frequency of the earphone sound with playback effect.

Description

technical field [0001] The invention relates to audio equipment, in particular to an earphone capable of optimizing the sound quality of reproduced sound. Background technique [0002] With the development of science and technology and people's pursuit of high-quality life, earphones have become indispensable in people's lives, such as earphones used in audio-visual equipment such as MP3 and MP4, and mobile communication devices such as mobile phones and handheld computers. [0003] At present, the earphone mainly includes a voice coil and a diaphragm, and the voice coil and the diaphragm are fixed together; the bottom of the diaphragm is provided with a dust cover. The earphone also includes a permanent magnet. The changing audio signal makes the voice coil cut the magnetic force line in the magnetic field formed by the permanent magnet. The force on the voice coil changes with the change of the audio signal and is transmitted to the diaphragm fixed with the voice coil. , ...

AI Technical Summary

Problems solved by technology

[0004] The problem existing in the existing earphones is that the audio signal processed by the amplifier circuit contains a large number of harmonics, which are returned to the amplifier circuit after being transmitted by the voice coil wire and accumulated continuously, which eventually leads to the unsatisfactory sound quality of the sound reproduced by the earphone.

[0005] In addition, when the diaphragm is pushed by the voice coil to vibrate, part of the energy is transmitted from the center of the diaphragm to the edge of the earphone, and this part of the energy is blocked by the edge and returns to the center of the diaphragm, resulting in transmission from the center of the diaphragm to the edge of the earphone. The energy of the earphone interferes, causing feedback distortion; and, due to the different frequencies of the treble, midrange, and bass transmitted through the earphones, the treble, midrange, and bass transmissions of the earphones are not synchronized, thereby destroying the full-band playback effect of the earphones.
