example 1
[0117] Example 1 (wired headset): Figure 8 It is a schematic structural diagram of the wired earphone circuit of the present invention. In the figure, 5-speaker, 7-microphone (mic), 8-volume control switch, 9-signal processing circuit, 10-plug, 11-signal data line, 21-signal amplifying circuit, such as Figure 8 As shown, a wired earphone, the existing wired earphones usually include a microphone 7, a signal processing circuit 9, etc., the prior art is that the audio signal collected by the microphone 7 is sent to the signal processing circuit 9, and after being processed by the signal processing circuit 9, And then transmitted, ..., sent to the human ear. Here, the special feature of the present invention is that a signal amplifying circuit 21 is also included between the microphone 7 and the signal processing circuit 9, and the audio signal collected by the microphone 7 passes through the signal amplifying circuit 21, and then input after being amplified. The signal proce...
