[0026] Referring to Figure 1, the intelligent music light string 20 includes a human body sensing module 21, a controller connected to the human body sensing module 22, and a control module 22, a music control module 23 connected to the control module 22, and a light string 24 connected to the control module 22. The human body sensing module 21 senses a human body and outputs a sensing signal when a human body is sensed. The control module 22 is configured to receive the sensing signal and output an enable signal and a control signal based on the sensing signal. The enable signal and control signal are output from different output terminals of the control module 22. The music control module 23 is configured to receive the enable signal and control the playback of preset music based on the enable signal. The light string 24 is configured to receive the control signal and operate in a preset mode corresponding to the preset music based on the control signal. An example of a preset mode corresponding to the preset music includes a working mode where the duty cycle of the control signal in each cycle corresponds to the beat of each segment of the preset music.

[0027] In this embodiment, the human body sensing module 21 senses the movement of the human body in real time through radar, thereby sensing the human body.

[0028] It is understood that in some embodiments, the human body sensing module 21 is a sensor, such as an infrared (IR) motion sensor, a passive infrared (PIR) sensor, an ultrasonic sensor, a capacitive sensor, a camera-based system, etc.

[0029] It is understood that in some embodiments, the control module 22 or the music control module 23 is part of the control device or a module of the control circuit system.

[0030] It is understood that in some embodiments, the smart music light string 20 can be replaced by other lighting devices, such as electric candles, projectors, etc.

[0031] In this embodiment, the chip model of the control module 22 is FMD FT61XX, and the chip model of the human body sensing module 21 is RCWL-0517.

[0032] In this embodiment, the control module 22 includes fourteen pins numbered 1 to 14. Pin 4 of the control module 22 is connected to the power supply and receives the power signal V+. Pin 11 of the control module 22 is grounded. The human body sensing module 21 includes three pins numbered 1 to 3. Pin 3 of the human body sensing module 21 is connected to the power supply and receives the power signal V+. Pin 1 of the human body sensing module 21 is grounded. Pin 2 of the human body sensing module 21 is connected to pin 13 of the control module 22. When the human body sensing module 21 senses a human body, pin 2 of the human body sensing module 21 outputs a sensing signal and provides the sensing signal to pin 13 of the control module 22. After receiving the sensing signal, the control module 22 outputs an enable signal through pin 9 and a control signal through pin 12.

[0033] In this embodiment, the smart music light string 20 also includes a button 25, one end of which is connected to the control module 22, and the other end of which is grounded. The button 25 is configured to control the control module 22 to output different adjustment signals via a digital 8-pin connector.

[0034] In this embodiment, the music control module 23 includes a music chip 231 and a speaker 232. The enable terminal of the music chip 231 is connected to the control module 22, and the output terminal of the music chip 231 is connected to the speaker 232. The music chip 231 is model EV3P087J and has eight pins, numbered 1 to 8. Pin 4 of the music chip 231 is connected to the power supply, receives the power signal V+, and is grounded through capacitor 233. Pin 5 of the music chip 231 is grounded. Pins 2 and 3 of the music chip 231 are connected to the positive and negative terminals of the speaker 232, respectively. Pins 6 and 7 of the music chip 231 are connected to pins 9 and 8 of the control module 22. The music chip 231 stores preset music. When the music chip 231 receives an enable signal, it controls the speaker 232 to play the preset music. When the music chip 231 receives the adjustment signal from pin 8 of the control module 22, the music chip 231 adjusts the volume of the speaker 232 according to the adjustment signal.

[0035] It is understood that in some embodiments, the music chip 231 or the speaker 232 may be a separate part of the control device or a separate module of the control circuit system.

[0036] In this embodiment, the light string 24 includes a protection resistor 241, an NPN transistor 242, and an LED string 243. One end of the protection resistor 241 is connected to the control module 22, and the other end is connected to the base of the NPN transistor 242. The collector of the NPN transistor 242 is connected to the negative terminal of the LED string, and the emitter of the NPN transistor 242 is grounded. The positive terminal of the LED string 243 is configured to be connected to the power supply signal V+. When the base of the NPN transistor 242 receives a control signal from pin 12 of the control module 22, the NPN transistor 242 turns on or off according to the control signal, thereby controlling the LED string 243 to emit light. Since the duty cycle of each cycle of the control signal corresponds to the beat of each segment of the preset music, the LED string 243 emits light according to the beat of the preset music. That is, the light string 24 emits light according to the beat of the preset music, without the need for external driving (such as a microphone), which has the advantage of low cost.

[0037] Understandably, the preset music has a defined rhythm, and the control signal can generate the rhythm manually based on this defined rhythm. For example, each piece of preset music includes strong and weak beats; when a strong beat is provided, the control signal's voltage level is high, and when a weak beat is provided, the control signal's voltage level is low. Strong and weak beats are provided periodically. Therefore, the control signal can control the LED string 243 to illuminate according to the rhythm of the preset music. Understandably, the duty cycle of the control signal is determined by the high voltage level within one cycle.

[0038] In this embodiment, the smart music stream 20 further includes an RF receiving module connected to the control module 22 and the remote controller 27, configured to connect to at least one of the following: the control module 22, the remote controller 27, a WIFI module 28 configured to connect to the control module 22, and a smart device 29. With this structure, the smart music stream 20 allows the user to select the control method according to their needs.

[0039] It is understood that in some embodiments, the smart device 29 may be a mobile phone, tablet computer, etc. Of course, the WIFI module 28 may also be replaced by a Bluetooth module or a 4G / 5G module.

[0040] Specifically, the WIFI module 28 may include four pins numbered 1 to 4. Pin 4 of the WIFI module 28 is connected to the power supply to receive the power supply voltage V+. Pin 1 of the WIFI module 28 is grounded. Pins 3 and 2 of the WIFI module 28 are connected to pins 2 and 2 of the control module 22, respectively. The RF receiver module 26 includes three pins numbered 1 to 3. Pin 3 of the RF receiver module 26 is connected to the power supply to receive the power supply voltage V+. Pin 1 of the RF receiver module 26 is grounded. Pin 2 of the RF receiver module 26 is connected to pin 1 of the control module 22.

[0041] This application has the following beneficial effects: Through the above structure, the human body sensing module 21 senses the human body in real time and outputs a sensing signal when a human body is sensed; the control module 22 receives the sensing signal and outputs an enable signal and a control signal according to the sensing signal, and the enable signal and the control signal are output from different output terminals; the music control module 23 receives the enable signal and plays preset music according to the enable signal; the light string 24 receives the control signal and starts working according to the control signal. The duty cycle of each cycle of the control signal corresponds to the beat of each segment of the preset music. At this time, the light string 24 lights up according to the beat of the preset music, without the need for external driving (such as a microphone), the structure is simple and the cost is low.
