Detailed Description

The invention is further described below by means of specific embodiments. The utility model discloses an each drawing only is the schematic in order to understand more easily the utility model discloses, its specific proportion can be adjusted according to the design demand.

It will be understood that when an element is referred to as being "connected" or "disposed" to another element, it can be directly on the other element or intervening elements may also be present, such that the element is connected to the other element via intervening elements. Conversely, when an element is referred to as being "directly on" or "directly connected to" another element, it is understood that there are no intervening elements explicitly defined

Fig. 1 is a perspective view of a notebook computer. FIG. 2 is a block diagram of a notebook computer. As shown in fig. 1 and 2, the notebook computer 1 includes a transceiver module 10, a noise reduction module 20, and a playing unit 30. The transceiver module 10 receives a remote audio signal St from the outside. The noise reduction module 20 is communicatively connected to the transceiver module 10, receives the remote audio signal St, and separates the remote audio signal St into a remote voice and a remote background sound, so as to convert the remote voice into a noise reduction remote audio signal Str. The playing unit 30 is connected to the noise reduction module 20 for receiving the noise-reduced remote audio signal Str, and performing electro-acoustic conversion to the remote sound Vtr for playing. Thus, it is possible to clearly distinguish the human voice from the sound transmitted from the remote, and hear the clear sound at the near end (user end).

Further, in some embodiments, the notebook computer 1 further includes a wave frequency adjusting module 50. The wave frequency adjusting module 50 receives the noise reduction remote audio signal St, adjusts the waveform of the noise reduction remote audio signal St to be the wave frequency adjustment remote audio signal Sta, and then sends out the adjusted remote audio signal Sta, for example, increases the gain (gain) of the human voice wave frequency to make the human voice graph show. The wave frequency adjustment module 50 may be disposed before the noise reduction module 20 or disposed after the noise reduction module 20.

In some embodiments, the notebook computer 1 further comprises a radio module 40. The radio module 40 receives the near-end sound Vn and converts it into a near-end audio signal Sn, and the noise reduction module 20 is further connected to the radio module 40 for receiving the near-end audio signal Sn, separating the near-end audio signal Sn into a near-end voice and a near-end background sound, and then converting the near-end voice into a noise-reduced near-end audio signal Snr, which is sent out by the transceiver module 10. In some embodiments, the signal may be further converted into a wave frequency adjusted near-end audio signal Sna through the wave frequency adjusting module 50 after the noise reduction module 20. The drawings are exemplary only, and not intended to be limiting, and the wave frequency adjustment module 50 may also be disposed before the noise reduction module 20. In more detail, the near-end audio signal Sn is a lossless compressed sound file.
