a kind of earphone

Abstract

The invention discloses an earphone, comprising a loudspeaker, a focus positioning tube and a guiding shell, wherein the guiding shell is a parabolic curve; the sound inlet end of the focus positioning tube is fixed at the bottom of the guiding shell and is in through connection with one end of the sound tube of the loudspeaker, while the sound outlet end is positioned on the focus of the parabolic curve; the loudspeaker is arranged below the bottom of the guiding shell, and the sound outlet of the loudspeaker faces the bottom of the guiding shell. Sound waves emitted by the focus positioning tube are projected out in a direction parallel to the axial direction of the focus positioning tube after being reflected by the guiding shell; and through installing the earphone on a necklace and aligning the opening of the guiding shell to an ear of a user, the sound waves can be directionally transmitted to the ear. According to the earphone wearing mode, on the one hand, the ear can simultaneously hear sound emitted by the earphone and sound from the outside, thereby being relatively safe when being used on the road; and on the other hand, the ear is prevented from being stimulated by strong sound pressure, the auditory system is not injured even in long-time use, and the earphone is comfortable to wear.

Description

technical field [0001] The invention relates to the field of acoustics, in particular to an earphone. Background technique [0002] The existing earphone structures are generally in-ear type and earmuff type. When using, the earphone needs to be inserted into the ear canal or covered on the auricle. These two types of earphones are in close contact with the ear during use. Defects in the following aspects. [0003] First of all, in-ear headphones need to be inserted into the ear canal, which can easily cause discomfort in the ear canal. At the same time, the earphones are wired and inconvenient to wear. The earmuffs are relatively bulky, and the clamping force of the headband is used to ensure the tight connection between the earmuffs and the ears and prevent sound leakage, so it is easy to cause discomfort to the head and ears. [0004] Secondly, long-term use of earphones and earmuffs can damage the auditory system and even affect hearing. [0005] In addition, due to t...
