Earplug rubber sleeve for in-ear earphone

Abstract

An earplug rubber sleeve for an in-ear earphone comprises a plug sleeve, a sound channel and an annular echo groove, the sound channel is of a cylindrical structure, and the plug sleeve is in an annular spherical shape; the sound channel is inserted into the plug sleeve, the upper end of the sound channel is flush with the upper edge of the plug sleeve, the lower end of the sound channel protrudesout of the lower edge of the plug sleeve, the annular echo groove is formed in the sound channel and protrudes towards the plug sleeve, and a cavity defined by the wall of the sound channel is formedin the sound channel. The in-ear earplug rubber sleeve is improved on the basis of a traditional in-ear earplug rubber sleeve; an annular echo groove structure is added; the cavity echo can be formedin the process of transmitting the sound in the sound channel; therefore, a better reverberation effect is achieved; sound quality of earphone is greatly improved, the reverberation effect can be greatly improved through the structure of the two annular echo grooves, the listening enjoyment of a user for different types of music is improved, meanwhile, sponge can be added into the plug sleeve, the influence of external noise on sound in the sound channel can be reduced to a certain degree, and the comfort degree of a wearer can be greatly improved.

Description

technical field [0001] The invention belongs to the technical field of earphones, and in particular relates to an earplug rubber cover for in-ear earphones. Background technique [0002] The earplug rubber cover of current in-ear earphone has a simple structure, only consists of a plug cover and a sound channel (attached) image 3 ), the sound effect of the earphone depends entirely on the pronunciation unit of the in-ear earphone. The earplug rubber sleeve only transmits the sound and fixes the ear, and it is difficult to improve the sound quality of the earphone. With the continuous improvement of people's music effect How to improve the sound quality through the structural design of the earphone cover has become a relatively new research direction in the current technical field. Therefore, it is urgent to provide an earplug cover that can improve the sound quality of the in-ear earphone through structural improvement. Contents of the invention [0003] In order to solve...
