[0044] The relevant circuit module is the relevant module of our company's previous patent. It is selected because it is more suitable for this scenario. Of course, other suitable relevant functional modules are also possible.

[0045] As a preferred embodiment of the present invention, the karaoke host further includes a QR code module, and the QR code module is used to quickly establish a communication connection with the karaoke host when a mobile device scans the QR code.

[0046] As a preferred embodiment of the present invention, a QR code module is also provided for the karaoke host. When other mobile devices scan the QR code module, they can quickly communicate and connect with the karaoke host, making it convenient for users to order songs on their mobile phones, further optimizing the user experience.

[0047] As a preferred embodiment of the present invention, the karaoke host further includes:

[0048] The operation prompt module is used to perform a broadcast reminder each time an operation is performed on the karaoke host.

[0049] Reference Figure 2 As a preferred embodiment of the present invention, the operation prompt module is specifically a buzzer-related circuit module, and the buzzer-related circuit module specifically includes the following circuits:

[0050] One end of the second resistor RP2 is connected to the BEEP pin of the karaoke host, the other end of the second resistor RP2 is connected to the base B of the transistor Q3, the emitter E of the transistor Q3 is grounded, the collector of the transistor Q3 is connected to one end of the buzzer LS1, the other end of the buzzer LS1 is connected to one end of the first resistor RP1, and the other end of the first resistor RP1 is connected to a power supply.

[0051] In this preferred embodiment, by using a buzzer as an operation prompt module, the purpose of the invention of this preferred embodiment can be better achieved at a low cost. It is only necessary to feed back a high level to the BEEP pin each time the karaoke host is operated.

[0052] Reference Figure 3 As a preferred embodiment of the present invention, specifically, the sleep module includes related circuits based on a 555 timing chip, as follows:

[0053] Pin 1 of the 555 timing chip is grounded, pins 2 and 6 of the 555 timing chip are respectively connected to one end of the capacitor C1 and one end of the resistor RP, the other end of the capacitor C1 is grounded, the other end of the resistor RP is respectively connected to one end of the resistor R1 and pin 7 of the 555 timing chip, the other end of the resistor R1 is respectively connected to pins 8 and 4 of the 555 timing chip and the positive electrode of the power supply XS1, pin 3 of the 555 timing chip is connected to the positive electrode of the capacitor C3, the negative electrode of the capacitor C3 is respectively connected to one end of the resistor R2 and the positive electrode of the speaker interface, the negative electrode of the speaker interface is grounded and the negative electrode of the power supply XS1, the resistor R2 is connected to one end of the headphone jack X, the other end of the headphone jack X is respectively connected to the positive electrode of the light-emitting diode VD1 and the negative electrode of the light-emitting diode VD2, the negative electrode of the light-emitting diode VD1 and the positive electrode of the light-emitting diode VD2 are grounded, pin 5 of the 555 timing chip is connected to one end of the capacitor C2, and the other end of the capacitor C2 is grounded.

[0054] The related circuit based on the 555 timing chip also includes that a disconnectable connection ab is provided between the other end of the headphone jack X and the positive electrode of the light-emitting diode VD1 and the negative electrode of the light-emitting diode VD2. When an external light-emitting diode is required, the connection ab is disconnected, and the other end of the headphone jack X is connected to the positive electrode of the external light-emitting diode, and the negative electrode of the external light-emitting diode is grounded, and a socket XS2 is provided at the corresponding external light-emitting diode.

[0055] In this preferred embodiment, the 555 timer chip and R1, RP, and C1 form a multivibrator. By pre-adjusting the resistance value of the resistor RP, the oscillator generates a low-frequency pulse signal of 0.7-14Hz. The signal is output from pin 3 of the 555 timing chip. After being isolated by the capacitor C3, the frequency range remains unchanged, the signal level is shifted down, and a negative pulse appears. The low-frequency signal is sent to the positive and negative parallel light-emitting diodes VD1 and VD2 through the resistor R2, the headphone jack, and points b and a. When the positive pulse of the low-frequency signal comes, VD1 is turned on and emits light. When the negative pulse of the low-frequency signal comes, VD2 is turned on and emits light. In this way, under the action of the low-frequency signal pulse, VD1 and V D2 will light up alternately. If the earphone is inserted into X, the low-frequency pulse signal will flow through the earphone, and a "ticking" sound can be heard in the earphone. If the connection between b and a is disconnected, and the light-emitting diode is connected in series between b and a, that is, inserted into the two ends of the XS2 socket, and a speaker is connected at SP+ and SP-, since the resistance of the speaker is very small, the current shunted by the speaker is very large. At this time, the headphone socket, VD1 and VD2 are not lit, and the speaker will make a "ticking" sound. The "ticking" sound is accompanied by the alternately flashing light-emitting diode. According to the theory of brain wave fatigue elimination, karaoke users can relieve fatigue and greatly improve the user's karaoke experience.

[0056] In addition, the signal frequency of the multivibrator can be calculated by the following formula:

[0057]

[0058] Based on the above, by changing the values ​​of R1 and R2, the signal frequency can be guaranteed to be between 0.7-14Hz, and then RP can be adjusted to find the frequency suitable for the user.

[0059] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
