Abstract
An earphone produces a three-dimensional stereo sound effect. The earphone has an ear cup with a front portion, a back portion, a front sound effect unit disposed in the front portion, a front sound resonator disposed in the front portion, a back sound resonator disposed in the back portion, and a back sound effect disposed in the back portion. A front speaker is disposed in the front portion of the ear cup. A back speaker is disposed in the back portion of the ear cup. A sound controller is disposed in the ear cup. A sound output unit is connected with the ear cup. The front speaker and the back speaker work together to create stereo sound in a first dimension and in a second dimension. One of the front speaker and the back speaker creates stereo sound in a third dimension.
