Preferably, the absolute direction sensor employs chips Adafruit-DOF Absolute Orientation IMU Fusion Breakout-BNO055.
Preferably, the cloth pressure sensor is formed by sewing upper cloth, lower cloth and conductive sponge clamped between the upper cloth and the lower cloth through a seam, wherein the upper cloth and the lower cloth are provided with conductive cloth with consistent positions and areas, and a resistor is connected in a region, which is not provided with the conductive cloth, of the lower cloth.
Preferably, the distribution pressure sensors are six, and are correspondingly arranged in six claws of the octopus doll.
Preferably, two buttons are provided at two eyes of the head of the octopus doll and are respectively used as a sound control switch and an absolute direction sensor initial value resetting switch, and the sound control switch and the absolute direction sensor initial value resetting switch are electrically connected with a Bela electronic interaction controller in the head of the octopus doll and the absolute direction sensor.
Preferably, an interface for connecting an external power supply and a sound is preset at the bottom of the octopus doll.
The invention has the technical effects that the invention is a modified version of a traditional Chinese instrument single-string instrument, the tone color of the single-string instrument is simulated by combining sensor technology, conductive cloth and other electronic technologies, so that the traditional instrument is more innovative and has imaginative and fun, the invention is compared with the traditional single-string instrument, the high tones at six different positions of the original strings are respectively modified in six claws of the novel digital instrument octopus, the function of the rocking rod of the single-string instrument is replaced by an absolute sensor and is placed at the head of the octopus, the design keeps the playing mode of rocking the rocking rod of part of the single-string instrument, but keeps the touch and texture of a plush doll, and compared with the traditional single-string instrument, the invention allows a plurality of sounds to be played simultaneously and expands the sound range generated by the traditional single-string instrument, and in addition, the invention introduces new electronic sound and performance technology on the basis of digital technology.

Detailed Description
The invention will be further described with reference to the accompanying drawings.
The digital musical instrument octopus comprises an octopus-shaped doll, wherein a Bela electronic interaction controller, an absolute direction sensor and a plurality of cloth pressure sensors are embedded in the doll, a connection relation block diagram of the hardware is shown in fig. 1, a circuit structure is shown in fig. 2, and the digital musical instrument octopus is specifically described as follows:
(a) And a Bela electronic interactive controller running Pure Data code and storing digital analog solo string sounds, wherein the Bela electronic interactive controller is an open source embedded computing platform developed specifically for high quality, ultra low latency interactive audio, the Bela electronic interactive controller providing stereo audio, analog and digital I/O in a single independent package, which combines the processing power of BeagleBoneBlack embedded computers with the timing accuracy and connectivity of the microcontroller, and the Pure Data code is an open source visual programming language for audio and video processing.
(B) An absolute direction sensor which integrates the functions of an accelerometer, a magnetometer, a gyroscope and the like and is used for sensing absolute directions, angular velocity vectors, acceleration vectors and linear acceleration vectors in a three-dimensional space;
(c) The cloth pressure sensors are respectively used for sensing the pressure;
Wherein the Bela electronic interaction controller and the absolute direction sensor are arranged at the head of the octopus doll together, and the plurality of cloth pressure sensors are sewn in the claw of the octopus doll
The absolute direction sensor adopts chips Adafruit-DOF Absolute Orientation IMU Fusion Breakout-BNO055.
As shown in fig. 3, the cloth pressure sensor is formed by sewing an upper layer cloth 1, a lower layer cloth 2 and a conductive sponge 4 sandwiched between the upper layer cloth 1 and the lower layer cloth 2 through a seam 6, wherein the upper layer cloth 1 and the lower layer cloth 2 are provided with conductive cloths 3 with consistent positions and areas, and a resistor is connected in a region where the lower layer cloth 2 is not provided with the conductive cloths 3. The conductive cloth is characterized in that conductive fibers are added on a traditional cloth structure, so that the conductive cloth has conductivity, and after the conductive cloth is combined with conductive sponge, the pressure acting on the surface can change the resistance value, so that the conductive cloth is used as a pressure sensor to sense the pressure.
The distribution pressure sensors are six, and are correspondingly arranged in six claws of the octopus doll.
Two buttons are arranged at the two eyes of the head of the octopus doll and are respectively used as a sound control switch and an absolute direction sensor initial value resetting switch, and the sound control switch and the absolute direction sensor initial value resetting switch are electrically connected with a Bela electronic interaction controller in the head of the octopus doll and the absolute direction sensor.
An interface for connecting an external power supply and a sound is preset at the bottom of the octopus doll.
The invention has the working principle that an absolute direction sensor and a cloth pressure sensor transmit sensing values to a Bela electronic interaction controller in real time, codes of PureData are operated in the Bela electronic interaction controller, digital analog single string sounds are stored in the Bela electronic interaction controller, after receiving a trigger signal of the cloth pressure sensor, the Bela electronic interaction controller plays corresponding sounds, and adjusts the volume according to pressure values, the Bela electronic interaction controller receives space dynamic values transmitted by the absolute direction sensor, adjusts the pitch of the played sounds through the change of the set of values, when a novel digital musical instrument octopus is connected with a power supply and a sound box, a player can trigger six different high-pitched single string instrument analog sounds through squeezing six octopus claws, the greater the squeezing strength is, the greater the volume is, and the player can change the pitch through shaking the heads of the octopus while the sounds are triggered.
