DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] Example 1

[0027] Specifically, a light strip A3 is provided above the platform 1 on one side of the base 2 and on the outer periphery of the platform 1 and the base 2. A teardrop-shaped base 4 is provided on the base 2. A MOS tube 5, an Arduino Uno control board 6, a plurality of solid-state relays 7 and a MIDI pad 8 are provided inside the teardrop-shaped base 4. The light strip A3 is electrically connected to the Arduino Uno control board 6 via the MOS tube 5.

[0028] Among them, MOS tube 5 is a field effect tube, which is a semiconductor device that uses the power plant effect of the control input loop to control the output loop current, that is, an insulating field effect tube in the integrated circuit; by setting MOS tube 5 in series with the light strip A3, the function of controlling the light strip A3 to turn on and off is achieved, and at the same time, MOS tube 5 can also achieve the effect of changing the color of the light strip A3.

[0029] The upper part of the water drop-shaped base 4 is inwardly recessed to form a seat platform 9, on which a pressure sensor 10 is provided, and a seat cushion 11 is also provided on the seat platform 9, and a liquid gel ice pad 12 for dispersing pressure is provided between the seat cushion 11 and the seat platform 9, and 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 seat platform 9, and at the same time, the fluidity of the liquid gel in the liquid gel ice pad 12 is utilized. When the seat cushion 11 is subjected to pressure, the gel of the liquid gel ice pad 12 is squeezed toward the surroundings, dispersing the pressure on the seat platform 9 to a certain extent, so that no matter where the pressure change occurs on the seat platform 9, the pressure sensor 10 can more sensitively detect the corresponding data of the pressure change of the seat cushion 11.

In this embodiment, the MIDI audio control signal generated by triggering different infrared photoelectric switches 13 turns on the corresponding solid-state relay 7, and the solid-state relay 7 is disconnected after the preset duration of conduction, thereby simulating the process of pressing and releasing the corresponding audio button on the MIDI strike pad 10, thereby realizing the performance of audio. When the Arduino Uno control board 6 generates a MIDI audio control signal, the corresponding solid-state relay 7 is controlled to turn on for a preset duration according to the MIDI audio control signal, and then disconnected, thereby realizing the short triggering of the corresponding audio button, so that the MIDI strike pad 10 emits the corresponding audio.

When a certain solid-state relay 7 is turned on, the corresponding audio button of the MIDI strike pad 8 is triggered, so that the MIDI strike pad 8 sends a corresponding audio signal, and the audio signal is output to the amplifier speaker 15 through the audio line connected to the audio interface 14, and then the corresponding sound is output.

[0034] The platform 1 is also provided with a number of bionic bamboos 16, which are distributed along one side of the water drop-shaped substrate 4 to enhance the aesthetics and ornamental properties of the device. The bionic bamboos 16 are each provided with a number of light strips B17, which can be wound or fixed on the bionic bamboo 16.

A button 18 is also provided on the water drop-shaped substrate 4 on one side of the infrared photoelectric switch 13, and the button 18 is electrically connected to the Arduino Uno control board 6. The button 18 is used to send a pressing signal, and the Arduino Uno control board 6 receives and controls the light strip B17 to present a corresponding lighting effect according to the pressing signal. In this embodiment, the Arduino Uno control board 6 is used to receive the pressing signal and match it with the lighting effect corresponding to the pressing signal stored in the Arduino Uno control board 6, generate a light strip control signal, and transmit the light strip B17 through the signal amplifier 19 to control the lighting effect presented by the light strip B17.

[0035] The signal amplifier 19 is used to amplify the light strip control signal from the Arduino Uno control board 6, so that one signal source can be used for multiple light strips, avoiding the problem of poor light-emitting effect of the lamp beads due to insufficient signal strength. In this embodiment, the light strip B adopts the WS2812 light strip, and the signal amplifier 192 adopts the SP901E light strip signal amplifier 19.

[0045] The sound control method S1 comprises the following steps: S11: tapping the infrared photoelectric switch 13 to trigger the infrared photoelectric switch 13 to emit an electrical signal.

[0046] S12: The Arduino Uno control board 6 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 13, and outputs the signal.

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.
