Referring to fig. 1, the optical noise test system 100 includes a sound muffling box 110, a microphone 120, a light source 130, a light source controller 140, an audio analyzer 150, and an upper computer 160. Wherein the microphone 120 and the light source 130 are located within the sound muffling box 110. The sound muffling box 110 is used for isolating sound waves outside the sound muffling box 110 through the wall of the sound muffling box 110, so that the sound waves outside the sound muffling box 110 cannot be received by the microphone 120.
The emergent light of the light source 130 irradiates the sound hole of the microphone 120, and a signal conversion circuit for converting a sound wave signal into an electric signal is arranged in the microphone 120. The conversion circuit comprises various metal lines and electronic elements. Therefore, when light is irradiated to the signal conversion circuit of the microphone 120 through the sound hole, the conversion circuit generates a current due to a photoelectric effect, thereby causing noise of the microphone 120 due to light irradiation.
Further, in order to make it possible to customize variables when the optical noise test is performed by the optical noise test system 100, the optical noise test system 100 further includes a light source controller 140, where the light source controller 140 is connected to the light source 130 and is used to control the light emitting parameters of the light source 130 and/or the on/off of the light source 130.
When the microphone 120 generates noise due to the photoelectric effect, it is necessary to acquire a signal characteristic of the noise generated due to the photoelectric effect. Therefore, the optical noise testing system 100 further comprises an audio analyzer 150, wherein the audio analyzer 150 is connected to the microphone 120, and the audio analyzer 150 is configured to perform noise analysis on the audio signal output by the microphone 120. That is, when the microphone 120 generates noise due to the photoelectric effect, in order to determine specific noise parameters of the noise signal, such as ac/dc voltage of the signal, signal frequency, harmonic distortion, spectrum analysis result, 1/3 octave analysis result, sound pressure level measurement result, the noise signal may be input to the audio analyzer 150 to obtain the specific parameters of the noise information through the audio analyzer 150.
It should be noted that, in order to enable the optical noise testing system 100 to automatically generate an accurate optical noise testing result, the optical noise testing system 100 further includes an upper computer 160, and the upper computer 160 is connected to the audio analyzer 150 and is configured to determine the optical noise testing result according to the noise analysis result output by the audio analyzer 150.
Optionally, in an embodiment, an adapter plate 170 may be provided between the microphone 120 and the audio analyzer 150, since the microphone 120 is small, inconvenient to install and inconvenient to wire. The adapter plate 170 is connected to an output end of the microphone 120, and the adapter plate 170 is configured to extract an output signal of the microphone 120. The interposer 170 includes a first connection terminal and a second connection terminal, and the first connection terminal and the second connection terminal are electrically connected; the output terminal of the microphone 120 is electrically connected to the first connection terminal, and the second connection terminal is electrically connected to the input terminal of the audio analyzer 150. Illustratively, the interposer 170 may be configured as a PCB board. The output end of the microphone 120 is welded to the first terminal of the adapter plate 170, and the second terminal is connected to the input end of the audio analyzer 150 through a signal line.
Alternatively, since the brightness of the normal visible light source is low, the low brightness light generally cannot cause the microphone 120 to generate noise due to the photoelectric effect. For example, if the Light source 130 is a common visible Light source (e.g., a low-power incandescent lamp), the brightness of the sound hole of the microphone 120 may be lower than 2000 lumens, and the microphone 120 may not generate noise due to the photoelectric effect, and the common visible Light source may generally only emit white Light, but may not emit monochromatic Light, and thus, the Light noise generated by the test Light with different Light colors may not be tested. Therefore, as an embodiment, the light source 130 may be configured as a laser light source. To enable testing of the effect of light of different colors on the microphone 120, the laser light source 130 may include a red sub-light source, a blue sub-light source, and a yellow sub-light source (not shown), so that the laser light source 130 may emit test light of different colors, such as red light, blue light, or yellow light.
Further, when the light source 130 is set as the laser light source 130, the light source controller 140 may include a relay, a control end of the relay is connected to the upper computer 160, an input end of the relay is connected to the power supply of the optical noise testing system 100, an output end of the relay is connected to the red sub light source, the blue sub light source and the yellow sub light source, output ends of the red sub light source, the blue sub light source and the yellow sub light source are different, and the control end is used for switching the output end of the input end communication, so that the upper computer 160 of the optical noise testing system 100 may control different sub light sources connected to the power supply through the relay of the light source controller 140, and the laser light source 130 is controlled to emit the testing light of different colors.
It can be understood that the upper computer 160 is connected to the light source controller 140, and the light source controller 140 is configured to receive a control signal sent by the upper computer 160, and control the red sub-light source, the blue sub-light source, and the yellow sub-light source to emit light according to the control signal.
It should be noted that, in the present embodiment, since the light source 130 is the laser light source 130, and the laser light source 130 includes the sub-light sources capable of emitting visible light with different light colors, the optical noise testing system 100 can test the influence of the visible light with different light colors on the microphone 120 with true sensitivity. In addition, the brightness of the laser power supply can be controlled by controlling the voltage of the power supply connected with the laser light source 130, and the laser light source 130 is controlled to flicker by controlling the on-off between the power supply and the laser light source 130, so that the noise generated by illumination is changed, and the independent variable in the optical noise test process is increased.
Alternatively, as another embodiment, the light source 130 may be an infrared light source 130, for example, the light source 130 may be an infrared LED; the light source controller 140 is a signal generator 140, and an output signal of the signal generator 140 is used for exciting the infrared light source 130 to emit infrared light, wherein voltage values of the excitation signal are different, wavelengths of the infrared light emitted by the infrared light source 130 are also different, that is, the output signal of the signal generator 140 is adjustable. And further, the signal generator 140 can control the infrared light source 130 to emit infrared light with different wavelengths as the test light by changing the voltage value of its output signal.
Optionally, the signal generator 140 may be connected to the upper computer 160, so as to adjust the voltage value of the output signal according to control information issued by the upper computer 160, or determine the voltage value of the output signal according to a trigger state of an output voltage adjustment button disposed on a control panel of the signal generator. Thereby enabling a user to adjust the voltage value of the output signal by adjusting the trigger state of the output voltage adjustment button.
It should be noted that, in the optical noise testing system 100 provided by the present invention, the light source 130 can be controlled to emit different testing lights, and the audio analyzer 150 analyzes the noise signal generated by the microphone, and further the upper computer 160 determines the optical noise testing result based on the risk result of the noise signal, thereby achieving the effect of determining the influence of the light on the microphone 120.

The data interface 1004 may optionally include a standard wired interface, the data interface 1004 for interfacing with a light source controller and an audio analyzer of an optical noise testing system. The memory 1005 may be a high-speed RAM memory or a non-volatile memory (e.g., a magnetic disk memory). The memory 1005 may alternatively be a storage device separate from the processor 1001.
Those skilled in the art will appreciate that the terminal structure shown in fig. 1 is not intended to be limiting and may include more or fewer components than those shown, or some components may be combined, or a different arrangement of components.

and sending a control signal corresponding to the test control parameter to a light source controller so that the light source controller controls the sub-light source corresponding to the test control parameter to emit light according to the control information.
Further, the processor 1001 may call the optical noise test control program stored in the memory 1005, and further perform the following operations:
and determining the light-emitting parameters according to the test control parameters.
Further, the processor 1001 may call the optical noise test control program stored in the memory 1005, and further perform the following operations:

and determining the light-emitting parameter according to the output parameter.
Referring to fig. 3, in an embodiment of the optical noise testing method of the present invention, the optical noise testing method includes the following steps:
step S10, the upper computer receives the noise analysis result output by the audio analyzer and acquires the light emitting parameter of the light source;
and step S20, determining a light noise test result according to the noise analysis result and the light-emitting parameters.

The noise parameters may include signal ac/dc voltage of the noise signal, signal frequency, harmonic distortion, spectrum analysis results, 1/3 octave analysis results, sound pressure level measurement results, and the like.
And after the noise parameters are obtained, the light-emitting parameters corresponding to the light source in the current test process can also be obtained. When the light source is a laser light source, the light emitting parameters may include light intensity, light color, and flashing frequency of the light source during light emitting. When the light source is an infrared light source, the light emitting parameter may include a wavelength of infrared light.
After the upper computer obtains the light-emitting parameters and the noise parameters, the corresponding relation between each sub-light-emitting parameter and each sub-noise parameter can be determined, namely, the variation relation that one sub-light-emitting parameter is used as an independent variable and the sub-noise parameter is used as a dependent variable is determined.
Example 1, signal frequencies corresponding to different light colors (red, yellow and blue) were used as a set of data in the test results.

Or, the voltage of the power supply connected with the corresponding sub-light source can be controlled to control the corresponding sub-light source to emit the test light with different light intensities.
Further, since the light emitting parameters of the light source can be controlled by the upper computer, the light emitting parameters can be directly determined according to the control parameters.
