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."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"3D stereo earphone with multiple speakers","description":"An earphone produces a three-dimensional stereo sound effect.
