An earphone with a speaker ring contains: a sound guiding tube, a speaker, and a body. The sound guiding tube is connected with the body, and the speaker is disposed in the sound guiding tube. The speaker has a first O ring fitted on a front end thereof and a second O ring fitted on a rear end thereof, and the first O ring and the second O ring are defined between the speaker and the sound guiding tube. Thereby, the first O ring, the second O ring, and the third O ring are arranged between the speaker and the sound guiding tube to reduce the resistance between the speaker and the sound guiding tube, thus increasing tone quality. |
