[0016] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0017] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but rather merely represents selected embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort are also within the scope of protection of the present invention.

[0018] refer to Figure 1 and Figure 2 As shown, a new musical instrument includes a water drop-shaped base 1, an Arduio single-chip microcontroller 2, several solid-state relays 3, a trigger sound module (not shown in the figure) and a power supply module 5.

[0019] Specifically, the upper portion of the teardrop-shaped base 1 is inwardly recessed to form a seat 5 , on which a cushion 6 is provided. The user of the novel musical instrument sits on the cushion 6 to use the novel musical instrument.

[0020] The Arduio single-chip microcontroller 2 and the solid-state relay 3 are arranged inside the teardrop-shaped base 1. The trigger sound module includes a plurality of infrared photoelectric switches 7 spaced apart on the teardrop-shaped base on one side of the seat 5 and a MIDI performance pad 8 arranged inside the teardrop-shaped base 1. An audio interface 9 is provided on one side of the teardrop-shaped base 1. The audio interface 9 is electrically connected to the MIDI performance pad 8 and is connected to a speaker 11 via an audio cable 10.

[0021] Among them, the infrared photoelectric switch 7 is electrically connected to the Arduio microcontroller 2, and the Arduio microcontroller 2 is used to collect the electrical signal emitted when the infrared photoelectric switch 7 is triggered, and convert the electrical signal into a corresponding MIDI audio control signal according to the position of the triggered infrared photoelectric switch 7. The solid-state relays 3 are electrically connected to the Arduino microcontrollers 2 respectively, and the solid-state relays 3 are electrically connected to the audio buttons on the MIDI pad 8 in a one-to-one correspondence; the Arduino microcontroller 2 turns on the corresponding solid-state relay 3 according to the generated MIDI audio control signal, thereby triggering the audio button corresponding to the MIDI pad; the MIDI pad 8 is provided with audio buttons, and the different MIDI audio control signals correspond to different audio buttons, and the corresponding audio buttons are triggered by the MIDI audio control signal.

[0022] In this embodiment, MIDI audio control signals generated by different infrared photoelectric switches 7 are triggered to turn on corresponding solid-state relays 3. After a preset duration, solid-state relays 3 are turned off, thereby simulating the process of pressing and releasing corresponding audio keys on MIDI pads 8, thereby achieving audio performance. When the Arduino microcontroller 2 generates a MIDI audio control signal, it controls the corresponding solid-state relays 3 to turn on for a preset duration and then turn off, thereby briefly triggering the corresponding audio key, causing MIDI pads 8 to emit the corresponding audio.

[0023] The present invention adopts an infrared photoelectric switch as a photoelectric switch, triggering the infrared photoelectric switches 7 at different positions to emit different electrical signals. When the plurality of infrared photoelectric switches 7 arranged at intervals detect being tapped, the tapped infrared photoelectric switch 7 emits an electrical signal and outputs it to the Arduio single-chip microcomputer 2. The Arduio single-chip microcomputer 2 converts the electrical signal into a corresponding MIDI audio control signal according to the position information of the infrared photoelectric switch 7 corresponding to the electrical signal. The Arduino single-chip microcomputer 2 turns on the corresponding solid-state relay 3 according to the generated MIDI audio control signal, thereby triggering the audio button corresponding to the MIDI pad, so that the MIDI pad 8 emits a corresponding audio signal, and outputs the audio signal to the speaker 11 through the audio cable 10 connected to the audio interface 9, and then outputs the corresponding sound.

[0024] In this embodiment, the distance between adjacent infrared photoelectric switches 7 is 6-8 cm, and the detection distance of the infrared photoelectric switches 7 is 0-1 cm. The new musical instrument can be played by contact or proximity.

[0025] The power module 5 is disposed within the teardrop-shaped base 1 and electrically connected to the Arduino microcontroller 2 to provide power to the Arduino microcontroller 2. In this embodiment, the power module 5 includes a battery built into the teardrop-shaped base 1 and a charging port provided on the inner wall of the teardrop-shaped base. The new musical instrument is powered by the battery, which is then connected to an external power source via the charging port.

[0026] The teardrop-shaped base 1 is also provided with a switch button 12, which is electrically connected to the power module 5. The switch button 12 is used to power on and off the Arduio microcontroller 2, that is, to power on and off the new musical instrument.

[0027] The working principle of the present invention is as follows: when a user uses the present musical instrument to play, he can sit on the cushion 6 of the seat 5, and then gently tap the infrared photoelectric switches 7 at different positions with his hands. After the infrared photoelectric switches 7 at different positions send different electrical signals to the Arduio single-chip microcomputer 2, the Arduio single-chip microcomputer 2 converts the electrical signals into corresponding MIDI audio control signals according to the position information of the infrared photoelectric switches 7 corresponding to the electrical signals. The Arduino single-chip microcomputer 2 turns on the corresponding solid-state relay 3 according to the generated MIDI audio control signal, thereby triggering the audio button corresponding to the MIDI pad; the solid-state relay 3 is disconnected after being turned on for a preset time, and stops triggering the corresponding audio button; and then by tapping the infrared photoelectric switches 7 at various positions multiple times, the MIDI pad 8 sends corresponding audio signals in sequence, and the audio signal is output to the speaker 11 through the audio cable 10 connected to the audio interface 9, and the corresponding sound is output, completing the performance of a piece of music.

[0028] Compared with traditional musical instruments, the utility model has a novel shape and is easy to operate. Songs can be played by simply tapping, which simplifies the playing operation, lowers the threshold for playing musical instruments, and adds fun to life.
