[0027] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0028] The new multifunctional packaging box provided by the utility model is mainly used for product packaging. It enhances visual and auditory effects through atomizing films, luminous parts and resonance boxes, effectively improving the market competitiveness of products and consumers' purchasing desire. Moreover, after the product is used up, the packaging box can be reused as a sound amplification device and a storage box to improve the utilization rate of the packaging box and be more environmentally friendly.

[0029] See also Figure 1 and Figure 2 The utility model provides a new multifunctional packaging box, including a box body 1, on which an atomizing film 2, a light-emitting component 3, a resonance box 4 and a control component 5 are arranged. The atomizing film 2 and the light-emitting component 3 are arranged on the front and / or side of the box body 1, and the resonance box 4 is arranged at one end of the box body 1. The atomizing film 2 and the light-emitting component 3 are both connected to the control component 5, and the control component 5 controls the working states of the atomizing film 2 and the light-emitting component 3.

[0030] Under normal conditions, the atomization film 2 is in a blurred state and the light-emitting component 3 does not emit light. When the control component 5 makes the atomization film 2 work, the atomization film 2 becomes transparent and can make the light-emitting component 3 emit light. At this time, the products (such as cigarettes, wines, watches, mobile phones, or other gifts) placed behind the atomization film 2 can be clearly seen. Moreover, the use of the atomization film 2 and the light-emitting component 3 can improve the visual effect of the products, and the special texture is also easy to attract consumers. Through the light-emitting component 3, lighting can be reminded and the products can be better displayed.

[0031] Furthermore, the present utility model also enables the packaging box to interact with an external sound source through the resonance box 4, so that the packaging box can also be used as an amplifying device continuously without causing waste and being more environmentally friendly.

[0032] A pattern 6 is also provided on the front and / or side of the box body 1, and the light-emitting component 3 is arranged around the pattern 6. The pattern 6 can be a brand image, logo, characteristic art work or other visual elements related to the product. In this embodiment, the light-emitting component 3 is a light-emitting fiber. The light-emitting fiber is usually composed of a light-emitting material and a conductive fiber. When an electric current passes through the conductive fiber, the light-emitting material will be excited and emit light. It can have various light-emitting modes, such as constant light, flashing, gradual change, etc. These light-emitting modes can be achieved by controlling the electric current. The light-emitting fiber has the advantages of being soft, bendable, durable, etc., and can adapt to different shapes and requirements. Of course, the light-emitting component 3 can also be an LED lamp, as long as it can meet the requirements of product packaging, and there is no limitation here. Preferably, the light-emitting component 3 is a light-emitting fiber.

[0033] The novel multifunctional packaging box further includes a player 7. The player 7 is arranged at the other end of the box body 1, and the player 7 is connected to the control component 5. Through the player 7, product promotion audio or other sound effects, such as holiday greetings, music, etc., can be played, which can further enhance the brand effect, increase the attractiveness of the products, and can also customize the playback of voices, sound effects, etc. according to different products or consumer needs to meet specific market positioning and consumer needs.

[0034] Please refer to Figure 3, the resonance box 4 includes a recess 41 for placing an external player 40, a resonance cavity 42, and an adjustment component 43 for adjusting the size of the resonance cavity 42. The recess 41 has a sound passage hole or sound passage slit (not shown in the figure) communicating with the resonance cavity 42. The principle of the resonance cavity 42 is based on the resonance phenomenon. Resonance means that when an object is externally excited, if the excitation frequency is the same as or close to the natural frequency of the object, the object will generate strong vibrations. In the resonance box 4, the natural frequency of the resonance cavity 42 matches the frequency of the sound, so that the sound is strengthened in the cavity. When the sound enters the resonance cavity 42, the sound waves will be repeatedly reflected and superimposed in the resonance cavity 42 to achieve the effect of increasing the sound effect and enhancing the sound. In use, the user places the external player 40 (such as a mobile phone, a tablet computer, a wireless speaker, etc.) in the recess 41. The sound of the external player 40 enters the resonance cavity 42 through the sound passage hole and is broadcast after being resonated by the resonance cavity 42 to achieve the effect of amplifying the sound and adjusting the sound effect.

[0035] Among them, the volume in the resonance cavity 42 affects the reflection and superposition mode of the sound waves, thereby affecting the characteristics of the sound. Through the adjustment component 43, the user can adjust the size of the resonance cavity 42 according to personal preferences to adjust the resonance effect. When the volume of the resonance cavity 42 is small, the reflection and superposition of the sound waves in the cavity are more frequent, making the energy of the sound more concentrated and the sound sounding louder and clearer. This is because the smaller volume restricts the propagation and diffusion of the sound waves, enabling the sound waves to interact better. On the contrary, when the volume of the resonance cavity 42 is large, the number of reflections and superpositions of the sound waves in the cavity decreases, the energy distribution of the sound is more dispersed, and the sound sounds relatively soft and low. The larger volume provides more space for the sound waves, enabling the sound waves to propagate and diffuse more freely.

[0036] Optionally, the adjustment component 43 includes a knob 431, a driving gear 432, a driven gear 433, a lead screw 434, and a baffle 435. The knob 431 is placed on the box body 1. The driving gear 432 is coaxially connected to the knob 431. The driven gear 433 meshes with the driving gear 432. The lead screw 434 is arranged on the driven gear 433. The baffle 435 is sleeved on the lead screw 434, and the baffle 435 is movably arranged in the box body 1. When the knob 431 rotates, the driving gear 432 meshes and rotates with the driven gear 433, and when the lead screw 434 rotates, it drives the baffle 435 to move along the lead screw 434 to adjust the size of the resonance cavity 42 to change the resonance effect. The driving gear 432, the driven gear 433, and the lead screw 434 can be made of metal or wear-resistant plastic to ensure the service life of the adjustment component 43. Scales or marks can be set on the knob 431 to provide feedback to the user so that they know the current size setting of the resonance cavity 42.

[0037] Please refer toFigure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 , the control component 5 includes a control switch 51, an atomization driving unit 52, a light-emitting driving unit 53, a switch sensing unit 54, and a control unit 55.

Among them, the control switch 51 is a sliding switch that can be slidably arranged on the box body 1. The switch sensing unit 54 is located below the control switch 51 and is used to sense the position of the control switch, making the operation intuitive and easy to operate.

[0038] In this embodiment, when the control switch 51 is in the initial position (closed position), the light-emitting member 3 and the player 7 are in the off state, and the atomization film 2 is in the atomization state. When the control switch 51 slides to the music-on position, the music sounds. When the control switch 51 slides to the light-and-window-on position, the light-emitting member 3 lights up, and the atomization film 2 becomes transparent, and the products inside the box can be seen. When the control switch 51 is slid back to the closed position, all the electronic devices are turned off.

[0039] The switch sensing unit 54 includes a first magnetic control switch U1, a second magnetic control switch U2, a first resistor R1, and a first capacitor C1. The VDD pins of the first and second magnetic control switches U2 are connected to the first power supply terminal VDD through the first resistor R1 and are also grounded through the first capacitor C1. The OUTPUT pins of the first and second magnetic control switches U2 are connected to the control unit 55.

[0040] The control unit 55 includes a microcontroller U6, which can use a voice control chip of TRSF1602. The first magnetic control switch U1 can use N8400, and the second magnetic control switch U2 can use N9400. A magnetic control switch is a device that uses a magnetic field signal to control the on / off of a circuit, including normally open or normally closed types. The first magnetic control switch U1 is set at Figure 4 the "closed" position of Figure 4 the "light-and-window-on" position of

[0041] Optionally, a magnetic sheet (not shown in the figure) is provided below the control switch 51. In the initial state, the control switch 51 is in the "off" position. At this time, the music, atomization, and lighting function modules do not work. When the control switch 51 slides downward, the OUTPUT pin of the first magnetic control switch U1 outputs a high level to the PC4 pin of the microcontroller U6. At this time, the PWMP pin of the microcontroller U6 outputs a high level, and the PWMN pin outputs a low level, causing the player to play music. When the control switch 51 continues to slide downward to the "turn on light and window" position, the second magnetic control switch U2 senses the control switch 51, and its OUTPUT pin outputs a high level to the PC7 pin of the microcontroller U6. The microcontroller U6 causes the atomization drive unit 52 and the lighting drive unit 53 to work.

[0042] The lighting drive unit 53 includes: a first triode Q1, a second triode Q2, a step-up flyback transformer U3, a second resistor R2, a third resistor R3, a fourth resistor R4, a fifth resistor R5, a second capacitor C1, a third capacitor C2, and a fourth capacitor C4. The first triode Q1 and the second triode Q2 both form an oscillation circuit. The step-up flyback transformer U3 can use a step-up component with the model I MPINJ-M7-Monza-127B. The lighting component is a lighting fiber with a diameter of 0.2 mm, an operating temperature of -30°C to 180°C, and a lighting intensity of 5 - 100 cd / m 2 。

[0043] The base of the first triode Q1 is connected to the control unit 55 and one end of the third resistor R3 through the second resistor R2, and is also connected to the other end of the third resistor R3, one end of the third capacitor C2, and one end of the fourth resistor R4 through the second capacitor C1. It is also sequentially connected to the collector of the second triode Q2 and the VIN1 pin of the step-up flyback transformer U3 through the fifth resistor R5 and the fourth capacitor C4. The emitter of the first triode Q1 is connected to the second power supply terminal VEL and the emitter of the second triode Q2. The collector of the first triode Q1 is connected to the other end of the third capacitor C2 and the VIN2 pin of the step-up flyback transformer U3. The other end of the fourth resistor R4 is connected to the base of the second triode Q2. The VOUT1 pin and the VOUT2 pin of the step-up flyback transformer U3 are connected to both ends of the lighting component.

[0044] The atomization drive unit 52 includes a boost chip U4, an atomization film drive chip U5, an MOS transistor Q3, an MOS transistor Q3, a seventh resistor R7, a first inductor L1, a second inductor L2, and a diode D1. The boost chip U4 can use a boost chip U4 with the model ST—90, and the atomization film drive chip U5 can use an electronic atomization film drive chip U5 with the model SG-130VA. The MOS transistor Q3 is an N-channel MOS transistor Q3, and when the gate is at a low level, the MOS transistor Q3 conducts.

[0045] The gate of the MOS transistor Q3 is connected to the control unit 55 through the MOS transistor Q3, and is also connected to the second power supply terminal VEL and the source electrode of the MOS transistor Q3 through the seventh resistor R7. The drain electrode of the MOS transistor Q3 is connected to the VIN pin of the boost chip U4. The EN pin of the boost chip U4 is connected to the positive electrode of the diode D1 and the SW pin of the boost chip U4 through the first resistor R1. The negative electrode of the diode D1 is connected to the fourth power supply terminal VLED, one end of the second inductor L2, and the HON pin of the atomization film driving chip U5. The other end of the second inductor L2 is connected to the COIL pin of the atomization film driving chip U5. The EL2 pin and the EL1 pin of the atomization film driving chip U5 are respectively connected to the two connection terminals of the atomization film.

[0046] When the control switch 51 slides downward to the "turn on light and window" position, the second magnetic control switch U2 senses the control switch 51, and its OUTPUT pin outputs a high level to the PC7 pin of the microcontroller U6. At this time, the PC6 pin of the microcontroller U6 outputs a low level, causing both the first triode Q1 and the second triode Q2 to form an oscillation circuit to work, driving the boost flyback transformer U3 to work, boosting the 3V voltage to between 100V and 150V, and making the light-emitting fiber (i.e., the light-emitting component 3) light up. At the same time, the low level output by the PC6 pin of the microcontroller U6 also turns on the MOS transistor Q3. The boost chip U4 boosts the 3.7V to 6V to supply power to the atomization film driving chip U5, causing the atomization film driving chip U5 to work and power on the atomization film, turning it into a clear state. Conversely, when the control switch 51 slides upward to the "turn on light and window" position, the light-emitting fiber goes out, and the atomization film is powered off and becomes an atomization state. When the control switch 51 continues to slide upward to the "off" position, the player is turned off.
