Description

Terminal and terminal pickup method The present application claims priority from the national intellectual property agency, application number 202410251577.3, chinese patent application entitled "terminal and terminal pick-up method," filed on day 3 and 5 of 2024, the entire contents of which are incorporated herein by reference. Technical Field The application relates to the field of terminals, in particular to a terminal and a terminal pickup method. Background In order to improve user experience sense, generally be equipped with pickup module in the terminal. The pickup module not only can be used for common audio collection, but also can be used in application environments such as voice call and video call. The pickup module currently used by terminals is typically a microphone. And adopt the microphone to need to set up into sound hole or gap on the shell of terminal, can increase pickup structural design's complexity. Disclosure of Invention The application provides a terminal and a terminal pickup method, which solve the problem that the complexity of a pickup structure design is increased when a microphone is adopted in the existing terminal. In order to achieve the above purpose, the application adopts the following technical scheme: In a first aspect, a terminal is provided, including a main body portion, a pickup module, and a control module. The main body part is provided with a first surface, the first surface is a surface facing a user, and the first surface comprises a display surface. The pickup module sets up in the main part, and the pickup module includes radar module. The radar module is located inside the first face. The radar module is used for emitting a detection beam towards the first surface, receiving and processing echoes which pass through the first surface and enter the main body part, and outputting a first electric signal outwards. The control module is in communication connection with the pickup module. The control module is used for receiving the first electric signal, detecting whether Doppler frequency shift data are contained in the first electric signal or not, and analyzing and obtaining an audio signal according to the Doppler frequency shift data. When the user speaks, the skin at the mouth, throat, chin, etc. of the user vibrates, and the vibration is generally small, which causes the echo to generate doppler effect, and thus doppler shift occurs. The echo thus carries vibration information, i.e. doppler shift data, related to the user's speech. The echo is received and processed by the radar module and then can generate a first electric signal, the first electric signal is transmitted to the control module, the control module analyzes and processes the first electric signal to extract the characteristics related to the audio, namely Doppler frequency shift data, then a Mel-spectrogram (Mel-spectrogram, abbreviated as Mel spectrum) and the like can be generated according to the Doppler frequency shift data, then the corresponding audio signal is generated through voice recovery of the Mel-spectrogram, and finally the audio signal can be output or stored after noise reduction and the like. Therefore, the terminal provided by the embodiment of the application can realize the sound pickup function by replacing the microphone with the radar module, the radar module can be arranged in the terminal, and the surface of the terminal can be provided with no sound inlet holes or gaps or fewer sound inlet holes or gaps, so that the appearance of the terminal is attractive and complete, and the complexity of the sound pickup structure design can be reduced to a certain extent. In addition, because the radar module is located inside the terminal, need not to set up in side, the bottom etc. of terminal because reasons such as pleasing to the eye, can just set up to the human mouth, the radar module can set up in the pickup position of preferred promptly to better pick up the sound that the user sent, consequently adopt the terminal that this embodiment provided, can improve pickup quality to a certain extent. In a possible implementation manner of the first aspect, the main body portion includes a supporting device and a screen assembly disposed on the supporting device, the display surface is a surface of the screen assembly facing away from the supporting device, and at least a portion of the radar module is disposed on the screen assembly. Because during the use, user's face generally faces screen subassembly, adopts the scheme that this embodiment provided, can make the detection wave beam that radar module sent can reach the position that can take place vibration when user's sound production, like mouth, throat and chin etc. to vibration information that is correlated with it when user talks that can be better received, so that the audio quality that the terminal finally picked up is better. In a possible implementation manner of the first aspect, the screen assembly include
