Abstract
The invention relates to the technical field of earphones, in particular to an earphone with an improved structure. The earphone comprises a shell. A holding chamber is formed in the shell. A loudspeaker is installed in the holding chamber and is connected with an audio signal transmission line. The audio signal transmission line is in electrical signal connection with the loudspeaker. The holding chamber comprises a first sound chamber and a second sound chamber, wherein the first sound chamber is arranged on the front side of the loudspeaker and the second sound chamber is arranged on the rear side of the loudspeaker. The loudspeaker is fixed at the rear end part of the first sound chamber. The first sound chamber and the second sound chamber are isolated from each other and are respectively communicated with the external part of the sound outlet side of the shell. When the earphone works, one part of sound made by the loudspeaker is transmitted out of the shell through the first sound chamber and sound outlets and the other part of the sound is transmitted out of the shell through the second sound chamber and the sound outlets, wherein the sound which enters the second sound chamber is reverberated in the second sound chamber and can compensate bass insufficiency. Thereby, the earphone has the advantages of good bass effect and strong sense of stereophonic sound.
