Problems solved by technology

However, there are many disadvantages in the design of the two guide tubes. First, when replacing the mouthpiece, the tube body needs to be disassembled and reassembled, so it is very inconvenient; It is easy for the patient to bring saliva and food residue into the air intake pipe together, which will gradually block the air intake pipe, and at the same time, it is easy to breed bacteria, which poses a threat to the health of the user

Embodiment 1

[0029] Embodiment 1 of the present invention provides a kind of electronic wind instrument mouthpiece based on Bernoulli's principle, as Figure 4 As shown, this type of electronic wind instrument generally includes the following parts: a number of physical switch buttons or electrical touch buttons for finger fingering input and scale control; an optional bite controller for real-time adjustment of the tone when playing; a breath control system , used to detect the blow or inhale of the player, and control the tone in real time; other optional controllers are used to adjust the tone during performance; function buttons and display components.

[0030] Such as figure 1 As shown, the electronic wind instrument mouthpiece includes a plastic shell 1, and the space enclosed by the shell 1 is provided with two regions, a first air chamber 2 and a second air chamber 3, figure 1 The lower layer is the first air chamber 2, and the upper layer is the second air chamber 3, and the two ...

Embodiment 2

[0045] Embodiment 2 of the present invention provides an electronic wind instrument based on Bernoulli's principle, including the tube body 11 and the mouthpiece structure in Embodiment 1, and the electronic wind instrument is composed of the tube body 11 and the mouthpiece. at the same time as image 3 As shown, the first end of the tube body 11 is formed with a connecting portion 17 , and the connecting portion 17 and the mouthpiece are connected through a sleeve 18 and fixed by screws 15 . A second circuit board 16 is installed on the panel of the connecting portion 17, and the exposed metal pad on the second circuit board 16 is pre-pressed with the ejector pin 14 on the blowing nozzle to form an electrical connection.

[0046] A plurality of buttons are arranged in the middle of the tube body 11, including fingering control buttons 19 on the front and sides and function buttons on the back. The function buttons include a switch button 20, a menu button 21 for turning page...

Abstract

The invention provides an electronic wind instrument scheme based on a Bernoulli principle. An electronic wind instrument blowing nozzle comprises a shell, a first air chamber and a second air chamber, the first air chamber and the second air chamber are formed in the shell, the first air chamber is communicated with the second air chamber, two ends of the first air chamber are respectively connected with an air inlet and an air outlet, and air pressure sensor is arranged in the second air chamber, detects the absolute pressure in the second air chamber, and compares the absolute pressure with a standard value to obtain the air flow rate in the first air chamber. Through the arrangement of the first air chamber and the second air chamber, detection of airflow in the blowing nozzle is converted into absolute pressure, the problem of interference of flowing of the airflow on sensor detection is avoided, more sensitive airflow detection can be completed through the air pressure sensor in the second air chamber, the complexity of the production process and the installation cost are effectively reduced, meanwhile, the risk and residence degree of saliva and food residue blockage are remarkably reduced, and the service life is prolonged.

Description

technical field [0001] The invention relates to the field of electronic musical instruments, in particular to an electronic wind instrument mouthpiece and an electronic wind instrument based on the Bernoulli principle. Background technique [0002] Electronic wind instrument is a new type of electronic musical instrument that has appeared on the market in recent years. Its essence is to simulate real brass wind music, woodwind wind music and other wind instruments. It is simple, easy to learn, rich in timbre and fingering, and diverse in playing methods. [0003] Current electronic wind instruments typically use off-the-shelf airflow sensors with air inlets and outlets. Correspondingly, the mouthpiece part adopts a double guide tube design, one inlet tube is connected to the air inlet of the sensor, and one outlet tube is connected to the air outlet of the sensor, and the change of air pressure is detected by the air circulating inside the sensor . However, there are many...
