Description

Technical Field

[0001] The utility model relates to the field of music practice equipment, in particular to an electronic slide MIDI controller suitable for trombone players. Background Art

[0002] The trombone is a wind brass instrument that changes pitch by pushing and pulling the main tuning slide in coordination with mouth movements. Both the pushing and pulling of the tuning slide and the adjustment movements of the mouth are extremely difficult to master and require long-term practice to reach a high level. The trombone is an extremely difficult instrument to play. Not only does it require a large amount of air to be exhaled by the lungs and surrounding muscles to vibrate the lips, but the mouth also bears the huge pressure brought by the mouthpiece. Especially when playing high notes, the situation is even more serious. As the mouth muscles fatigue, the playing accuracy and endurance will correspondingly decline. In addition, the trombone produces a huge volume of sound and is not suitable for home practice without sound insulation treatment. There are already many MIDI controllers that simulate real wind instruments, such as the EWI (electric wind instrument) designed by AKAI for woodwind instruments, and various derivative woodwind fingering electronic MIDI controllers; there are also electronic harmonicas (DM48 by Lekholm Instruments), electronic trumpets (AKAI EVI1000), and so on. However, there has never been a MIDI controller designed for trombone players. Content of the Utility Model

Through this device, an external sound source and an amplification device can be connected to achieve the purpose of performance or practice.

[0004] To solve the above technical problem, the technical solution provided by the utility model is an electronic slide MIDI controller suitable for trombone players, which includes an exhalation sensing device, a slide pushing and pulling device, a left hand control device, and a processing device; the slide pushing and pulling device includes a slide rail, a push-pull plate slidably connected to the slide rail, a driven wheel U-shaped fixing plate fixed to one end of the slide rail, a driven wheel U-shaped mounting plate slidably connected to the driven wheel U-shaped fixing plate, a driven wheel rotatably connected to the driven wheel U-shaped mounting plate, a connecting plate fixed to the other end of the slide rail, a driving wheel rotatably connected to the connecting plate, a rotary encoder fixed to the rotating shaft of the driving wheel, a transmission belt is arranged between the driving wheel and the driven wheel, an adjusting rod is fixed to the rear end of the driven wheel U-shaped mounting plate, a thread is provided at the end of the adjusting rod, a through hole for the adjusting rod to pass through is provided at the rear end of the driven wheel U-shaped fixing plate, and a tension adjusting knob is threadedly connected to the adjusting rod.

[0005] Further, the exhalation sensing device includes a mouthpiece connector fixedly connected to the connecting plate, a mouthpiece connected to the intake end of the mouthpiece connector, an air duct connected to the outlet end of the mouthpiece connector, and a gas pressure sensor connected to the air duct.

Obviously, the described embodiments are some but not all of the embodiments of the present utility model. Usually, the components of the embodiments of the present utility model described and illustrated in the accompanying drawings here can be arranged and designed in various different configurations.

[0016] Embodiment 1, in combination with the attached Figures 1-4 , an electronic slide trombone MIDI controller suitable for trombone players, including an exhalation sensing device, a slide trombone push-pull device, a left hand control device, and a processing device;

[0017] The slide trombone push-pull device includes a slide rail 1, a push-pull plate 2 slidably connected to the slide rail 1, a driven wheel U-shaped fixing plate 3 fixedly connected to one end of the slide rail 1, a driven wheel U-shaped mounting plate 4 slidably connected to the driven wheel U-shaped fixing plate 3, a driven wheel 5 rotatably connected to the driven wheel U-shaped mounting plate 4, a connecting plate 6 fixedly connected to the other end of the slide rail 1, a driving wheel 7 rotatably connected to the connecting plate 6, and a rotary encoder 8 fixedly connected to the rotating shaft of the driving wheel 7. A transmission belt 9 is provided between the driving wheel 7 and the driven wheel 5. An adjusting rod is fixedly connected to the rear end of the driven wheel U-shaped mounting plate 4. The end of the adjusting rod is provided with a thread. A through hole for the adjusting rod to pass through is provided at the rear end of the driven wheel U-shaped fixing plate 3. The adjusting rod is threadedly connected with a tension adjustment knob 23. By screwing the tension adjustment knob 23, the adjusting rod is driven to move, the driven wheel U-shaped mounting plate 4 is driven to move, and the driven wheel 5 is driven to move, thereby adjusting the tension of the transmission belt 9.

[0018] The exhalation sensing device includes a nozzle connector 10 fixedly connected to the connecting plate 6, a nozzle 11 connected to the intake end of the nozzle connector 10, an air duct 12 connected to the outlet end of the nozzle connector 10, and a gas pressure sensor 13 connected to the air duct 12.

[0019] The left - hand control device includes a grip 14 fixedly connected to the lower part of one end of the slide rail 1, an interval control touch key 15 and an octave touch roller 16 provided on the grip 14, and a reset switch 17 provided under the end of the slide rail 1 where the connecting plate 6 is located. Both the interval control touch key 15 and the octave touch roller 16 adopt capacitive touch - sensing metal. There are two interval control touch keys 15, thus having two intervals.

[0020] The processing device includes a circuit - board mounting plate 18 fixedly connected to the slide rail 1 and a micro - processor circuit board 19 provided on the circuit - board mounting plate 18. A 5DIN interface 20 and a power switch 21 are provided on the circuit - board mounting plate 18, and the gas pressure sensor 13 is mounted on the circuit - board mounting plate 18. The interval control touch key 15, the octave touch roller 16, the reset switch 17, the gas pressure sensor 13, and the rotary encoder 8 are electrically connected to the processing device.

[0021] Rollers 22 are rotatably connected to both the upper and lower ends of the push - pull plate 2. The rollers 22 are in contact with the slide rail 1 and can roll relative to the slide rail 1, so as to realize the sliding of the push - pull plate 2 relative to the slide rail 1, with small frictional resistance.

[0022] When the present utility model is specifically implemented, it is connected to an external software - and - hardware synthesizer and an amplification system with MIDI input through the 5DIN interface 20. Hold the grip 14 with the left hand, blow air through the mouthpiece 11 with the mouth. The gas pressure sensor 13 senses the start and end time of the performer's exhalation and the exhalation strength, so as to simulate the attack and decay of the sound and the volume control during trombone performance. Push and pull the push - pull plate 2 with the right hand, change the position of the push - pull plate 2, drive the rotary encoder 8 to rotate through the movement of the transmission belt 9, thereby converting the position of the push - pull plate 2 pushed and pulled by the right hand into a digital signal, simulating the action of pushing and pulling the slide of the trombone. Through the interval control touch key 15 and the octave touch roller 16, the thumb of the left hand controls the selection of the octave, and the index finger of the left hand controls the selection of two interval relationships, so as to achieve the purpose of simulating the control of the harmonic series by the lips of brass instruments. The selection of two groups of intervals also serves the purpose of avoiding the difficult low - position of the trombone that is frequently used. The digital signals obtained through the exhalation sensing device, the slide pushing - pulling device, and the left - hand control device are input into the micro - processor circuit board 19. The micro - processor circuit board 19 has a program written specifically for this device. Through the operation of the micro - processor circuit board 19, a series of MIDI signals are output, and the external software - and - hardware synthesizer and amplification system with MIDI input can emit sounds and have the unique musical expression characteristics of the trombone.
