Description

Technical Field

[0001] The utility model belongs to the technical field of electronic musical instruments, and particularly relates to an electronic digital kazoo. Background Art

[0002] The kazoo belongs to the aerophone in wind instruments and is an ancient musical instrument, often used for playing during celebrations or special festivals. As long as the performer can hum a song, he can play the kazoo and quickly master the playing skills. Playing the kazoo does not require learning music theory, memorizing scores, or even practicing. The sound of the kazoo is similar to that of the saxophone and trumpet. It can be played at any time and is a guest instrument for many foreign musicians and singers during performances. The structure of the kazoo is simple, and the membrane can be replaced (both plastic wrap and bamboo flute membrane can be used instead). One end of the kazoo is large and the other end is small. When playing, the large end is held in the mouth. Instead of blowing, the performer hums the tune with the throat, and the vibration of the vocal cords drives the vibration of the sound membrane on the kazoo to produce sound.

[0003] A fatal defect of the traditional kazoo is that its timbre is not pleasant, and sometimes the sound it emits even sounds like flatulence. Content of the Utility Model

[0004] The utility model aims to solve the problem that the timbre of the traditional kazoo is not pleasant, and further provides an electronic digital kazoo.

[0005] The technical solution adopted by the utility model is as follows:

[0006] An electronic digital kazoo includes a kazoo body, a sound vibration sensor, an MCU, a conversion unit, and a sound equipment; a sound vibration sensor is installed at the airway inside the kazoo body, the audio signal output by the sound vibration sensor is transmitted to the MCU, the MCU converts the audio signal into corresponding musical notes, then the MCU converts the musical notes into various musical instrument timbres through the conversion unit, and outputs them through the sound equipment.

[0007] The utility model has the following beneficial effects compared with the prior art:

[0008] The utility model takes the kazoo as the input signal and outputs various timbre signals, so that what is played is the kazoo, while the output sound is the sound of musical instruments such as erhu, bamboo flute, saxophone, etc. The above timbre transformation is realized by a module. It increases the playability of electronic musical instruments and at the same time creates an instrument that anyone who can hum a song can play without learning.

[0009] The utility model can effectively identify the emotional data of the played song, such as emotional signals like vibrato, bend tone, and glissando, through the sound vibration sensor, making the played music particularly emotional. Description of the Drawings

[0016] As Figure 1 , Figure 2 shown, the present utility model provides an electronic digital kazoo, including a kazoo body 1, a sound vibration sensor 2, an MCU 3, a conversion unit and audio equipment 4; a sound vibration sensor 2 is installed at the air passage inside the kazoo body 1, the audio signal output by the sound vibration sensor 2 is transmitted to the MCU 3, the MCU 3 converts the audio signal into corresponding musical notes, and then the MCU 3 converts the musical notes into various musical instrument timbres through the conversion unit, and is output by the audio equipment 4.

[0017] The conversion unit adopts two schemes:

[0018] Scheme 1: The conversion unit includes an audio digital-to-analog conversion module 6 and a Tf card 5; the MCU 3 extracts the musical note waveform data in the Tf card 5, sends the musical note waveform data into the audio digital-to-analog conversion module 6, and the audio digital-to-analog conversion module 6 is used to convert the musical note waveform data into various musical instrument timbres (such as erhu, flute, saxophone and other musical instruments), and is output by the audio equipment 4. Use the Tf card 5 as the carrier of the timbre data and output it with the audio digital-to-analog conversion module 6.

[0019] Scheme 2: The conversion unit adopts a French Dream Chasing sound source chip 7. Use the French Dream Chasing sound source chip to emit the sounds of various musical instruments, such as erhu, flute, saxophone and other musical instruments.

[0020] AsFigure 3 As shown in the figure, the kazoo body 1 includes a housing 11, an air passage 12 and a mouthpiece; the mouthpiece is installed on the outside of the housing 11 and is in communication with the air passage 12 installed inside the housing 11.

[0021] The housing 11 includes an upper cover 111, a housing waterproof rubber strip 112, a bottom shell 114 and a plurality of bolts 115; a housing waterproof rubber strip 112 is provided between the upper cover 111 and the bottom shell 114, and the upper cover 111, the housing waterproof rubber strip 112 and the bottom shell 114 are fixed by a plurality of bolts 115; an installation hole for installing the mouthpiece is opened on one side of the bottom shell 114. The inside of the installation hole is in communication with the central cavity 121 of the air passage 12, and the mouthpiece passes through the installation hole and is inserted into the central cavity 121 of the air passage 12.
