3D (three-dimensional) eyeglasses

The invention discloses 3D (three-dimensional) eyeglasses which are fittingly used with 3D equipment. The 3D eyeglasses comprise a Bluetooth chip, 3D lenses and a microphone array module, wherein the 3D lenses and the microphone array module are respectively connected with the Bluetooth chip, and the microphone array module is used for acquiring sound signals and transmitting the acquired sound signals to the Bluetooth chip. The Bluetooth chip is used for receiving the sound signals input by the microphone array module and transmitting the sound signals to the 3D equipment and is further used for transmitting control signals to the 3D lenses. The 3D lenses is used for switching between an on state and an off state under the control signals transmitted by the Bluetooth chip. The 3D eyeglasses can solve the problem that acquisition range of the sound signals is limited and acquired sound signals are poor in quality in the process of video call by utilizing existing 3D eyeglasses.
