[0068] The preferred embodiment of the present application is described below with reference to the accompanying drawings.

[0069] Please refer to Figure 1 The control device of the preferred embodiment of the present application, and Figure 2 The block diagram of the signal processing of the preferred embodiment of the present application. The control device 1 of the present application is electrically connected to a microphone 20 and a display device D. The microphone 20 can receive the sound of the user speaking or the external sound and convert it into an electrical signal. The display device D can be a video display or the display of other electronic devices such as a notebook computer or the screen of a tablet computer.

[0070] The control device 1 of the present application has a body 10, an adjustment knob 11, an indicator light 12, and a second microprocessor 13. The adjustment knob 11, the indicator light 12, and the second microprocessor 13 are arranged in the body 10. The control device 1 performs work including a normal mode or a microphone gain setting mode, and the normal mode or the microphone gain setting mode is changed by the user. The adjustment knob 11 has a press mode F1 and a rotation mode F2, so that the adjustment knob 11 has two actuation modes of being pressed and being rotated. When the adjustment knob 11 is pressed, the second microprocessor 13 controls the switching to turn on the microphone gain setting mode of the control device 1, so that the control device 1 can perform the microphone gain setting. After the microphone gain setting is completed, the control device 1 automatically returns to the normal mode. When the control device 1 is in the normal mode, the control device 1 does not perform the microphone gain setting, but performs the microphone gain and volume control work according to the setting stored when the microphone gain setting was last performed. When the adjustment knob 11 is rotated, it is used to control and adjust the size of the volume, and does not trigger the microphone gain setting to be turned on.

[0071] In detail, the control device 1 of the present application comprises a signal gain amplifier 30, an attenuator 40, an analog-digital signal converter 50, an audio digital signal processor 60 and a first microprocessor 100. The signal gain amplifier 30, the attenuator 40, the analog-digital signal converter 50, the audio digital signal processor 60 and the first microprocessor 100 are all arranged in the body 10 and electrically connected to each other. The display device D of the preferred embodiment of the present application is taken as an example of a notebook computer, the display device D is electrically connected to the body 10 of the control device 1, and the display device D comprises a user interface 70 and a sound player 90, wherein the sound player 90 can also be arranged separately without being connected to the display device D. The microphone 20 is electrically connected to the body 10 of the control device 1.

[0072] Please see the accompanying drawings Figure 2 、 Figure 3A the display information schematic diagram of the display device of the preferred embodiment of the present application, Figure 3B the display information schematic diagram of the display device of the preferred embodiment of the present application and Figure 3C the display information schematic diagram of the display device of the preferred embodiment of the present application. When the user presses the adjustment knob 11, the control device 1 starts the microphone gain setting mode. At the same time, the user interface 70 of the display device D displays a first information 71 to prompt the user that the control device 1 will start to execute the microphone gain setting, and the user interface 70 of the display device D displays a second information 72 to prompt the user to emit a first sound 80 from the microphone 20 and last for a period of time. The microphone 20 receives the first sound 80 and generates a first electric signal 21. When the control device 1 receives the first electric signal 21, the user interface 70 of the display device D will display a setting information 711 to prompt the user that the microphone gain is being set, and the user interface 70 will display a sound prompt bar 721.

[0073] The first sound 80 emitted by the user to the microphone 20 will directly affect the size of the first electrical signal 21 generated by the microphone 20. When the first sound 80 is loud, the signal of the first electrical signal 21 will be large, and vice versa. Therefore, the control device 1 receives and detects the signal size of the first electrical signal 21, and detects whether the first electrical signal 21 reaches the optimal processable size and maintains stable output. When the control device 1 performs the microphone gain setting, if the first sound 80 emitted by the user to the microphone 20 is too loud, the control device 1 will also detect that the signal of the first electrical signal 21 is too large. At this time, the prompt light 12 of the control device 1 will light up to prompt the user to reduce the volume of the first sound 80 emitted to the microphone 20. At the same time, the user interface 70 of the display device D displays a sound prompt bar 721, and the sound prompt bar 721 has an optimal degree mark 722 to prompt the user whether the first electrical signal 21 generated by the first sound 80 emitted by the user reaches the optimal processable size and maintains stable output, and is suitable for continuing the microphone gain setting.

[0074] When the control device 1 receives and analyzes the first electrical signal 21, and the sound prompt bar 721 of the user interface 70 maintains the position of the optimal display mark 722, which represents that the detected first electrical signal 21 maintains the optimal degree, the control device 1 sets a microphone gain value, and the signal gain amplifier 30 amplifies the first electrical signal 21 according to the microphone gain value to generate a second electrical signal 31. The microphone gain value is 1 times to 1000 times, preferably 100 times to 500 times. For example, after the control device 1 analyzes the signal size of the first electrical signal 21, the control device 1 sets the microphone gain value to 100 times, and the signal gain amplifier 30 amplifies the first electrical signal 21 by 100 times according to the microphone gain value of 100 times, thereby generating the second electrical signal 31. At the same time, the user interface 70 of the display device D displays a third information 73 to prompt the user that the control device 1 has completed the microphone gain setting.

[0075] At the same time, the control device 1 stores the microphone gain value, and provides a sound output signal 61 according to the microphone gain value.

[0076] Further, when the signal gain amplifier 30 gain-amplifies the first electric signal 21 according to the microphone gain value to generate the second electric signal 31, the attenuator 40 of the control device 1 will attenuate the second electric signal 31 according to an attenuation value to generate a third electric signal 41. The function of the attenuator 40 is to attenuate the electric signal to reduce the volume of the sound generated. The attenuation value is 0% to 100%, and when the attenuation value is 0%, the electric signal is not attenuated, and the size of the gain-amplified electric signal is directly presented, and the sound played by the electric signal is the loudest. When the attenuation value is 100%, the electric signal is attenuated to 0, which is equivalent to attenuating the electric signal to no signal, and corresponds to no sound. For example, the control device 1 of the embodiment has a preset attenuation value of 20%, and the attenuator attenuates the second electric signal 31 by 20%, so that the size of the second electric signal is attenuated to 80% of the original signal size, and then the third electric signal 41 is generated, and the corresponding generated volume is about 80%.

[0077] When the third electric signal 41 is attenuated by the attenuator 40, the third electric signal 41 is received by the analog-digital signal converter 50, and the analog-digital signal converter 50 converts the third electric signal 41 into a fourth electric signal 51, which is a digital signal. The audio digital signal processor 60 can receive and process digital signals, so the audio digital signal processor 60 receives and processes the fourth electric signal 51, and the audio digital signal processor 60 generates a sound output signal 61. The first microprocessor 100 is electrically connected to the audio digital signal processor 60, and processes the sound output signal 61 generated by the audio digital signal processor 60. The first microprocessor 100 can convert the signal format of the sound output signal 61, and the first microprocessor 100 processes and converts the sound output signal 61 into a signal format that can be played by the sound player 90, so that the sound can be played.

[0078] When the adjustment knob 11 is turned, the attenuation value can be adjusted, so that the user can control the sound output signal 61, and thus adjust the volume.

[0079] The sound output signal 61 is received by the sound player 90 of the display device D or other electronic devices such as a sound speaker, so that the user can play the sound after gain amplification. At the same time, the volume can also be adjusted by the user.

[0080] Furthermore, if the control device 1 is in the normal mode, the control device 1 does not perform the microphone gain setting, but performs the microphone gain according to the setting stored when the microphone gain setting was performed last time. That is, when the control device 1 is in the normal mode, the user sends a second sound 80' to the microphone 20, and the control device 1 performs the gain amplification for the second sound 80' according to the setting microphone gain value set last time, to generate a sound output signal 61', which is converted by the first microprocessor 100 and then transmitted to the sound player 90 or other sound playing devices, such as a speaker or a loudspeaker.

[0081] The user does not need to perform the complicated and tedious gain setting operation again. The user only needs to operate the adjusting knob 11 of the control device 1 of the present application, to achieve the effects of microphone gain setting and volume adjustment, which is simple to operate and can achieve the best combination effects of microphone gain setting and volume adjustment.

[0082] The above description is only the preferred embodiments of the present application, and any equivalent changes or modifications made without departing from the spirit disclosed by the present application should be included in the scope of the present application.
