Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
Novel digital musical instrument octopus musical instrument, including the doll of an octopus shape, inlay a Bela electronic interaction controller, an absolute direction sensor, a plurality of cloth pressure sensor inside the doll, the connection relation block diagram of above-mentioned hardware is shown as figure 1, and circuit structure is as telling 2 shows, and the concrete description is as follows:
(a) a Bela electronic interactive controller, running Pure Data code and storing digital analog single-string musical instrument sound, wherein the Bela electronic interactive controller is an open source embedded computing platform, developed specially for high-quality, ultra-low delay interactive audio, the Bela electronic interactive controller provides stereo audio, analog and digital I/O in a single independent package, and combines the processing capability of the BeagleBoneBlack embedded computer with the timing precision and connectivity of the microcontroller; the Pure Data code is an open source visual programming language for audio and video processing.
(b) An absolute direction sensor, which is a sensor integrating functions of an accelerometer, a magnetometer, a gyroscope and the like, and is used for sensing an absolute direction, an angular velocity vector, an acceleration vector and a linear acceleration vector in a three-dimensional space;
(c) the cloth pressure sensors are respectively used for sensing the pressure;
wherein, the head of octopus doll is arranged in jointly to Bela electronic interaction controller and absolute direction sensor, a plurality of cloth pressure sensor makes up inside the claw of octopus doll
The Absolute direction sensor adopts a chip Adafruit 9-DOF Absolute organization IMU Fusion Breakout-BNO 055.
As shown in fig. 3, the cloth pressure sensor is formed by sewing an upper cloth 1, a lower cloth 2 and a conductive sponge 4 sandwiched therebetween through a seam 6, the upper cloth 1 and the lower cloth 2 are provided with conductive cloths 3 having the same position and area, and a resistor is connected to the lower cloth 2 in a region where the conductive cloth 3 is not provided. The conductive fabric is formed by adding conductive fibers to a traditional fabric structure, so that the conductive fabric has conductivity, and after being combined with conductive sponge, the resistance value of pressure acting on the surface can be changed, so that the conductive fabric can be used as a pressure sensor to sense the pressure.
Six cloth pressure sensors are adopted and correspondingly arranged inside six claws of the octopus doll.
