In one embodiment, the first microphone 921 may be connected to the PCB81 through a wire or a separate FPC. Wherein, the first microphone 921 and the second microphone 923 may be respectively disposed at two sides of the PCB 81; for example, when the main board 80 is mounted in the first housing assembly 10, the first microphone 921 corresponds to an outlet 1162 of a passage 1160 at a left front position of the first portion 112 of the main front case 11 to receive external sounds through the passage 1160, and the second microphone 923 corresponds to an outlet 1162 of a passage 1160 at a right front position of the first portion 112 of the main front case 11 to receive external sounds through the passage 1160. The first microphone 921 may also be supported by or secured to the first speaker 911. The second microphone 923 may also be supported by or secured to the second speaker 913.
The third microphone 925 and the fourth microphone 927 may be disposed at a lower position of the middle portion of the PCB81 and respectively correspond to the outlets 1242 of the two passages 1240 on the bottom plate 121 of the main rear case 12 to respectively receive external sounds through the two passages 1240. Since the third and fourth microphones 925 and 927 may be positioned below the PCB81, a support 929 may be provided between the PCB81 and the third and fourth microphones 925 and 927. That is, the third microphone 925 and the fourth microphone 927 may be supported by the support 929, and the support 929 may be fixed on the PCB 81. The third microphone 925 can be connected to the PCB81 through an FPC 926, and the fourth microphone 927 can be connected to the PCB81 through an FPC 928. In one embodiment, the FPCs 926 and 928 may be merged with the FPC 713 of the camera assembly 70 before being connected to the PCB 81. In other embodiments, the FPC 926 and the FPC 928 may be connected to the PCB81 separately, or the FPC 926 and the FPC 928 may be joined and then connected to the PCB 81.
By arranging the microphone assemblies 92 such that they interfere less with each other, the directivity differs more.
