Abstract
The invention relates to the technical field of earphones, in particular to an earphone with a two-loudspeaker structure. The earphone comprises a shell. A holding chamber is formed in the shell. Two loudspeakers are installed in the holding chamber, wherein one loudspeaker is a high-frequency loudspeaker and the other loudspeaker is a low-frequency loudspeaker. The high-frequency loudspeaker and the low-frequency loudspeaker are respectively connected with audio signal transmission lines. The audio signal transmission lines are respectively in electrical signal connection with the corresponding loudspeakers. A low-frequency sound chamber corresponding to the low-frequency loudspeaker is arranged in the shell and a high-frequency sound chamber corresponding to the high-frequency loudspeaker is arranged in the shell, wherein the low-frequency sound chamber and the high-frequency sound chamber are isolated from each other and are respectively communicated with the external part of the sound outlet side of the shell. High-frequency sound made by the high-frequency loudspeaker and low-frequency sound made by the low-frequency loudspeaker are transmitted to the external part of the sound outlet side of the shell. Two kinds of different-frequency sounds are mixed outside and finally the compensation of the high-frequency sound and the low-frequency sound is realized. The mutually compensated sounds can reach a good stereoscopic sound effect.
