Abstract: An earphone with at least one air orifice contains a body. The body includes at least one slot defined on a rear cap thereof, and each of the at least one slot has at least one air orifice formed therein. Thereby, the air discharges or draws to vibrate the speaker via the at least one air orifice to reduce resistance of the air against the speaker and to enhance tone quality, when the speaker vibrates in a closed space.

Abstract: A connecting structure for an earphone contains: a male connector and a female connector. The male connector includes a plug terminal and an insulation holder, the plug terminal has a locking portion adjacent to a bottom of the plug terminal, and the plug terminal has at least one protrusion extending outwardly from a peripheral side of the locking portion. The plug terminal is mounted in the insulation holder, and between the insulation holder and the plug terminal is defined an inserting groove. The female connector includes an insertion seat and a body. The body has a fixing portion inserted into the inserting groove, and the fixing portion has at least one alignment orifice corresponding to the at least one protrusion. The insertion seat is fixed in the body to electrically connect with the plug terminal.

Abstract: 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.
