Abstract
A multi-channel earphone module is provided. The earphone module comprises two earphone units for engaging with each respective ear of a user. Each earphone unit includes a housing, a front channel speaker, a rear channel speaker and a subwoofer channel speaker. The front and the back channel speaker are adjacent to each other within the housing. The subwoofer channel speaker is installed at the bottom of the housing. The axis of the front channel speaker and the axis of the rear channel speaker form an acute angle for reducing the overlapping or interference of acoustic sound waves and improving output sound quality.
