Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts fall within the scope of protection of the present invention.

[0025] Embodiment 1

[0026] Refer to Figure 1 Figure 2 and Figure 3 As shown, an acoustic-optic interaction performance device can be used as a prop device and / or a sound-emitting device and / or a light-emitting device in stage performances; the acoustic-optic interaction performance device includes a floor platform 1, and a base 2 is provided on the floor platform 1.

A water-drop-shaped matrix 4 is provided on the base 2. Inside the water-drop-shaped matrix 4, there are a MOS transistor 5, an Arduino Uno control board 6, several solid-state relays 7, and a MIDI percussion pad 8. The strip lights A3 are electrically connected to the Arduino Uno control board 6 through the MOS transistor 5.

[0028] Among them, the MOS transistor 5 is a field-effect transistor, a semiconductor device that uses the electric field effect of the control input circuit to control the current of the output circuit, that is, an insulated-gate field-effect transistor in an integrated circuit; by setting the MOS transistor 5 in series with the strip lights A3, the function of controlling the lighting and extinguishing of the strip lights A3 is realized, and at the same time, the MOS transistor 5 can also change the color of the strip lights A3.

[0029] An inward depression is formed above the water-drop-shaped matrix 4 to form a seating platform 9. A pressure sensor 10 is provided on the seating platform 9. A seat cushion 11 is also provided on the seating platform 9. A liquid gel ice pad 12 for dispersing pressure is provided between the seat cushion 11 and the seating platform 9. The pressure sensor 10 is located below the liquid gel ice pad 12. The pressure sensor 10 is used to detect the pressure change above the seating platform 9. At the same time, using the fluidity of the liquid gel in the liquid gel ice pad 12, when pressure is applied to the seat cushion 11, the gel of the liquid gel ice pad 12 is squeezed outwards, dispersing the pressure received by the seating platform 9 to a certain extent, so that no matter where the pressure change occurs on the seating platform 9, the pressure sensor 10 can more sensitively detect the corresponding data of the pressure change of the seat cushion 11.

[0030] The pressure sensor 10 is electrically connected to the Arduino Uno control board 6. The Arduino Uno control board 6 is used to receive the pressure value detected by the pressure sensor 10 and control the opening and closing of the light strip A3 according to it. In this embodiment, the Arduino Uno control board 6 receives the pressure value detected by the pressure sensor 10 and compares it with a preset pressure threshold, and then controls the opening and closing of the light strip A3. When the detected pressure value is lower than the preset pressure threshold, the Arduino Uno control board 6 controls the light strip A3 to close; when the pressure value is higher than the preset pressure threshold, the Arduino Uno control board 6 controls the light strip A3 to turn on.

When the Arduino Uno control board 6 generates a MIDI audio control signal, it controls the corresponding solid-state relay 7 to conduct for a preset duration and then disconnect according to the MIDI audio control signal, so as to realize the short-term triggering of the corresponding audio key, and make the MIDI percussion pad 10 emit the corresponding audio.

[0034] On the platform 1, there are also several bionic bamboos 16. The bionic bamboos 16 are distributed along one side of the water-drop-shaped base body 4 to enhance the beauty and ornamental value of the device. Several strip lights B17 are arranged on each of the bionic bamboos 16. The strip lights B17 can be wound or fixed on the bionic bamboos 16. A signal amplifier 19 is also arranged inside the water-drop-shaped base body 4. The strip lights B17 are electrically connected to the Arduino Uno control board 6 through the signal amplifier 19. On the water-drop-shaped base body 4 on one side of the infrared optoelectronic switch 13, there is also a button 18. The button 18 is electrically connected to the Arduino Uno control board 6. The button 18 is used to send a pressing signal. The Arduino Uno control board 6 receives the pressing signal and controls the strip lights B17 to present corresponding lighting effects according to the pressing signal.

[0035] Among them, the signal amplifier 19 is used to amplify the strip light control signal from the Arduino Uno control board 6, so that one signal source can supply multiple strip lights, avoiding the problem of poor light-emitting effect of the lamp beads caused by insufficient signal strength.

A control method for a sound and light interactive performance device, characterized in that: It is used for a sound and light interactive performance device as claimed in claim 5, including a sound control method S1 and a light control method S2, wherein the sound control method S1 comprises the following steps: S11: tap the infrared photoelectric switch to trigger the infrared photoelectric switch to send out an electrical signal; S12: The Arduino Uno control board receives the electrical signal, and converts the electrical signal into a corresponding MIDI audio control signal according to the position information of the triggered infrared photoelectric switch and outputs the signal; S13: the Arduino Uno control board turns on the corresponding solid-state relay according to the generated MIDI audio control signal, thereby triggering the audio button corresponding to the MIDI pad, so that the MIDI pad sends out the corresponding audio signal and outputs it; S14: After the solid-state relay is turned on for a preset time, the Arduino Uno control board disconnects the solid-state relay, thereby causing the MIDI pad to stop outputting the corresponding audio signal; S15: looping steps S11 to S14; The lighting control method S2 step comprises: S21: The pressure sensor detects the pressure value of the seat and transmits the pressure value to the Arduino Uno control board; S22: The Arduino Uno control board receives the pressure value, and compares the pressure value with a preset pressure threshold. When the pressure value is lower than the preset pressure threshold, the Arduino Uno control board controls the light strip A to turn off. When the pressure value is higher than or equal to the preset pressure threshold, the Arduino Uno control board controls the light strip A to turn on. S23: Press the button using different pressing modes to send corresponding pressing signals; S24: the Arduino Uno control board receives the pressing signal, matches the pressing signal with the pre-stored correspondence between the pressing signal and the light strip effect, and outputs a corresponding light strip control signal; S25: The signal amplifier receives and amplifies the light strip control signal, and then controls the light strip B to present a corresponding lighting effect through the amplified light strip control signal.
