The portable power source is arranged in the hollow bamboo body and used for providing power.
Preferably, the hollow bamboo body is in a hollow tubular shape, two loudspeakers are respectively arranged at two end faces of the hollow bamboo body, and the resonance cavity of the bamboo can be used as a sound box for amplification and tone quality increase.
Preferably, a 10K resistor is connected between the flexible sensor and the ground terminal of the Bela electronic interaction controller to protect the Bela electronic interaction controller and the circuit board.
The technical effects of the utility model: the utility model is a modified version of the single-stringed instrument of the traditional Chinese musical instrument, and simulates the tone of the single-stringed instrument by combining the sensor technology, the sound synthesis technology and other electronic technologies, so that the traditional musical instrument is more innovative and has imagination and fun; the utility model discloses realize that sound is synthesized and is realized in pure data, this data is local operation in the interactive controller of Bela electron, through the algorithm that has used Karplus-Strong synthetic sound to and the input has been attached to flexible sensor, with real-time regulation pitch, this kind of modulation will influence the frequency of the starting frequency of tone and the frequency of last ringing tone, and in addition, reverberation and delay effect can add the end of synthesizing the chain according to player's judgement.
Drawings
Fig. 1 is a structural view of the present invention.
Fig. 2 is a flow chart of the sound synthesis of the present invention.
Fig. 3 is a schematic circuit diagram of the present invention.
In the figure: 1. the musical instrument comprises a hollow bamboo body, 2 copper paper touch strips, 3 a control lever, 4 a loudspeaker, 5 a Bela electronic interaction controller, 6 a Trill touch sensor.
Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
A novel digital musical instrument finger organ adopts a hollow bamboo organ body 1 as a basic organ body, and the hollow bamboo organ body 1 is in a hollow tubular shape. A plurality of copper paper touch strips 2 are uniformly distributed on the upper surface of the hollow bamboo body 1 along the horizontal direction; a control rod 3 and a loudspeaker 4 are arranged on the hollow bamboo body 1, and a flexible sensor is vertically arranged on the control rod 3; inlay Bela electronic interaction controller 5 and Trill touch sensor 6 in hollow bamboo musical instrument body 1's inside, wherein, carry out Data transmission through the I2C bus between Bela electronic interaction controller 5 and the Trill touch sensor 6, operation has Pure Data code and stores with digital simulation's sound in Bela electronic interaction controller 5, Trill touch sensor 6 and a plurality of copper paper touch strip 2 electric connection respectively.
The Bela electronic interactive controller 5 (also called Bela open audio hardware platform) is an ultra-low delay single board computer designed for digital musical instruments. The Bela electronic interaction controller 5 is the brain of a novel digital musical instrument finger organ; the Bela electronic interaction controller 5 receives the capacitive touch information from the Trill touch sensor 6 and synthesizes the sound using the Pure Data application. This digital information will then be converted to an analog signal and sent to the loudspeaker 4.
The Trill touch sensor 6 is a Trill Craft capacitive touch sensor, and can receive capacitance data of at most 30 channels. The touchpad operates on a capacitively coupled system, can detect and measure any conductive or dielectric other than air, and then transmits touch data from a Trill Craft capacitive touch sensor to the Bela electronic interaction controller 5 using the I2C bus protocol.
The flexible sensor flexible potentiometer is connected to the joystick 3 to sense changes in motion, the flexible sensor detects the amount of deflection applied to the joystick 3 and sends this data to an analog input on the Bela electronic interactive controller 5, which is used to adjust the tone in the synthesis algorithm; and a 10K resistor is connected between the flexible sensor and the grounding end of the Bela electronic interaction controller 5 so as to protect the Bela electronic interaction controller and the circuit board.
Two loudspeakers 4 are respectively arranged at two end faces of the hollow bamboo body 1, namely: the audio signal is implemented using two loudspeakers 4 which receive analogue signals from a Bela electronic interactive controller 5, the Bela electronic interactive controller 5 amplifying circuit supporting two channels of audio, 1W 8ohm each.
With a 16X copper paper touch bar, the 16X copper paper touch bar is used as a conductive button with a Trill Craft capacitive touch sensor. A Trill Craft capacitive touch sensor will receive a signal when an object with a dielectric lower than air makes contact with the touch bar.
The utility model discloses can be through domestic power supply or portable power source power supply, also can use and be similar to the 9V 2.1Amp portable power source that charges to the cell-phone.
The utility model discloses the theory of operation: capacitive touch Data is received by the Trill Craft capacitive touch sensor 6, transmitted to the Bela electronic interactive controller 5 by the I2C bus protocol, synthesized in Pure Data using the Karplus-Strong synthesis sound algorithm, while the flexible sensor detects the amount of deflection applied to the joystick 3 and sends this Data to the analog input on the Bela electronic interactive controller 5, which is used to adjust the tone in the synthesis sound algorithm, and finally converts the digital signal to an analog signal and emits sound through the speaker 4.
