Description of the Drawings

[0015] Figure 1 The circuit diagram of the display lamp control circuit of the utility model. Detailed Embodiment

[0016] The utility model will be described in detail below with reference to the drawings and embodiments. It should be noted that if there is no conflict, the embodiments of the utility model and the various features in the embodiments can be combined with each other, and all are within the protection scope of the utility model.

[0017] Please refer to Figure 1 , the utility model provides a display lamp control circuit, which includes a sound sensor P, a first comparator U1, a first capacitor C1, a first field effect transistor Q1, a waveform signal reference unit and a single chip microcomputer U3. The sound sensor P is electrically connected to the positive input end of the first comparator U1. The first end of the first capacitor C1 is electrically connected to the positive input end of the first comparator U1, and the second end of the first capacitor C1 is grounded. The source electrode of the first field effect transistor Q1 is grounded, the drain electrode of the first field effect transistor Q1 is electrically connected to the positive input end of the first comparator U1, and the gate electrode of the first field effect transistor Q1 is electrically connected to the output end of the first comparator U1. The negative input end of the first comparator U1 is used to be electrically connected to a first reference power supply.

[0018] The output terminal of the first comparator U1 is electrically connected to the single-chip microcomputer U3, and the waveform signal reference unit is electrically connected to the single-chip microcomputer U3. The single-chip microcomputer U3 is electrically connected to the display lamp and is used to control the operation of the display lamp according to the signals output from the waveform signal reference unit and the output terminal of the first comparator U1. It can be understood that the single-chip microcomputer U3, also known as a single-chip microcontroller, is an integrated circuit chip. The single-chip microcomputer is a super-small computer integrated on a silicon chip through very large scale integrated circuit technology, integrating functions such as CPU, RAM, ROM, input / output, interrupt system, timer / counter, etc. It is a prior art and will not be elaborated here.

[0019] The waveform signal reference unit includes a second capacitor C2 and a second comparator U2. The first end of the second capacitor C2 is electrically connected to the positive input terminal of the second comparator U2. The negative input terminal of the second comparator U2 is used to be electrically connected to the second reference power supply, and the second end of the second capacitor C2 is grounded. The output terminal of the second comparator U2 is electrically connected to the single-chip microcomputer U3. Among them, the first capacitor C1 matches the second capacitor C2. Since the first capacitor C1 matches the second capacitor C2, the influence of the input signal of the first comparator U1 on the reference oscillation period is the same as the influence of the input signal of the second comparator U2 on the detection oscillation period, so that the output signal is not affected by temperature changes.

The external power supply for adjustment is received through the negative input terminal of the second field-effect transistor Q2, and the second field-effect transistor Q2 is continuously turned on and off, so that the output terminal of the second field-effect transistor Q2 outputs a reference oscillation period signal.

The first end of the first resistor R1 is used to be electrically connected to the reference voltage, and the second end of the first resistor R1 is electrically connected to the negative input terminal of the second comparator U2. The first end of the third capacitor C3 is electrically connected to the first end of the first resistor R1, and the second end of the third capacitor C3 is grounded. The electrical signal input to the negative input terminal of the second comparator U2 is filtered through the first resistor R1 and the third capacitor C3, thus better avoiding misjudgment.

[0022] The waveform signal reference unit further includes a diode D and a second resistor R2. The anode of the diode D is grounded, the cathode of the diode D is electrically connected to the second end of the third capacitor C3, and the second end of the third capacitor C3 is grounded through the diode D. The first end of the second resistor R2 is electrically connected to the second end of the first resistor R1, and the second end of the second resistor R2 is grounded.

[0023] The waveform signal reference unit further includes a third resistor R3. The first end of the third resistor R3 is electrically connected to the second end of the third capacitor C3, and the second end of the third resistor R3 is electrically connected to the first end of the second resistor R2. Therefore, its filtering effect is better. The sound sensor P is a capacitive induction microphone. When the user is playing a game, different sound volumes can cause the first comparator U1 to output different signals, and the single-chip microcomputer U3 controls the display lamp to work according to different signals.

[0024] The present utility model also discloses a control device for a game display screen. It includes a display lamp and a display lamp control circuit. The display lamp is electrically connected to the display lamp control circuit, wherein the display lamp control circuit is the above-mentioned display lamp control circuit. Since the display lamp control circuit of the control device has the same structure as that of the display lamp control circuit in the above embodiment, it also has the same technical effects.

Since the control device of the game display screen has the same structure as that of the control device in the above embodiment, it also has the same technical effects.

[0026] In summary, since the first end of the first capacitor C1 of the present utility model is electrically connected to the positive input terminal of the first comparator U1, the second end of the first capacitor C1 is grounded, the source electrode of the first field-effect transistor Q1 is grounded, the drain electrode of the first field-effect transistor Q1 is electrically connected to the positive input terminal of the first comparator U1, the gate electrode of the first field-effect transistor Q1 is electrically connected to the output terminal of the first comparator U1, the output terminal of the first comparator U1 is electrically connected to the single-chip microcomputer U3, the waveform signal reference unit is electrically connected to the single-chip microcomputer U3, and the single-chip microcomputer U3 is electrically connected to the display lamp, and is used to control the display lamp to work according to the signals output by the waveform signal reference unit and the output terminal of the first comparator U1. Therefore, when the ambient temperature changes, the temperature coefficients of the detection oscillation periods of the waveform signal reference unit and the first comparator U1 are also basically the same, and their influence on the detected value of the sound sensor P is small, so it is not easy to make misjudgments, and the accuracy is improved.
