They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on the present invention.

[0020] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to direct connections, indirect connections through an intermediate medium, or internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.

[0021] The following is combined with Figure 1-5 The utility model is further described.

[0022] In order to solve the problems existing in the background technology, the present application proposes the following technical solution: an improved transverse flute for teaching.

[0023] The specific technical solution includes a flute body 1 and a tube sleeve 5. An opening 2 is provided at the mouthpiece of the flute body 1, a blowing hole 3 is provided on the outside of the flute body 1, and an airway groove 4 is provided on the outer surface of the flute body 1 and located between the opening 2 and the blowing hole 3. The depth of the airway groove 4 is 0.5-1.5 mm. The tube sleeve 5 is sleeved on the outside of the flute body 1. The tube sleeve 5 can be a card-type connection, but a slide rail groove 6 and a fully wrapped tube sleeve can also be achieved. In addition, all device materials involved in the content include but are not limited to bamboo, wood, artificial synthetic plastic, metal, jade, etc.

[0024] Two slide rail grooves 6 are provided on the outer surface of the flute body 1, and two slide rail bars 7 are fixed on the inner surface of the tube sleeve 5. The two slide rail bars 7 slide inside the two slide rail grooves 6 respectively. The sliding connection between the slide rail bars 7 and the slide rail grooves 6 is used to pull and limit the sliding direction and trajectory of the tube sleeve 5. A membrane hole 8 and multiple finger holes 9 are provided on the outside of the flute body 1. The membrane hole 8 is usually covered with a layer of professional flute membrane (reed membrane). When the player blows, the airflow passes through the membrane hole 8 and generates vibration. This vibration will affect the timbre of the flute, making it richer and fuller. The opening 2 is in a straight line with the blowing hole 3, the membrane hole 8 and the finger hole 9.

[0025] A flute plug 10 is provided inside the flute body 1. The flute plug 10 is located in the channel of the flute body 1, close to the blowing hole 3. The main function of the flute plug 10 is to help sound production. When the player blows, the air passes through the edge of the flute plug 10 and generates an air column vibration together with the flute body 1 cavity, thereby producing sound; when playing, the length of the vibrating air column is adjusted by opening and closing the finger holes 9, thereby achieving sound production of different high and low tones. The material and shape of the flute plug 10 will directly affect the timbre, pitch and volume. The flute plug 10 is usually made of cylindrical cork with flat ends and a thickness of about 7-13mm.

[0026] Example 1:

[0027] like Figure 1 As shown, the flute is now in the transverse playing state. The pipe sleeve 5 is moved upward to completely expose the traditional blowing hole 3, while covering the pre-opened opening 2, retaining the traditional transverse flute appearance, and at the same time using the most traditional transverse blowing method to play this improved flute.

[0028] Example 2:

[0029] like Figure 2As shown, the flute is in the upright playing state at this time, with the upper end of the tube sleeve 5 completely covering the pre-opened hole 2, and the lower end half covering the traditional blowing hole 3. This is the most unique way of playing the improved flute. The player blows air into the flute head, and the airflow flows through the channel between the pre-opened hole 2 and the airway groove 4 to reach the blowing hole 3, forming an oblique airflow, vibrating and producing sound.

[0030] Example 3:

[0031] like Figure 3 As shown, the flute is in the pre-playing state at this time. In order to prevent the blowing hole 3 from being contaminated and causing health effects on the player outdoors, the pipe cover 5 is directly moved down to completely cover the blowing hole 3, so as to protect the blowing hole 3 from being contaminated during the short period of time when the flute is not played.

[0032] Example 4:

[0033] like Figure 5 As shown, the flute is in the stop-play mode. Since the membrane of a traditional bamboo flute, which is a component that enhances the tone, is very thin and fragile and is particularly easy to be damaged, this mode directly moves the tube sleeve 5 down to above the membrane hole 8 so that the membrane hole 8 is completely covered, which can play the role of a membrane protector. When the flute is not played in most cases, this state can protect the membrane from damage by external forces to the greatest extent, maintain the integrity of the structure and function of the transverse flute, and it is very convenient to pick up and play without changing the membrane for a considerable period of time.

[0034] To enable those skilled in the art to fully understand the technical solution, this application provides the following overall overview:

[0035] When in use, an airway groove 4 is chiseled out through an opening 2 provided on the flute head and a blowing hole 3, and the airway groove 4 is connected with a pipe sleeve 5. A closed airway is formed outside the flute body 1 through a flute plug 10, simulating the player's oblique blowing airflow to cause the air in the flute body 1 to vibrate and produce sound, thereby achieving the function of being able to play the flute in either horizontal or vertical position, which is convenient for beginners to learn. The flute can be played in both horizontal and vertical positions by moving the pipe sleeve 5 on the front section of the flute body 1 without disassembling, helping beginners to overcome the difficulty of playing the flute and directly and quickly experience the charm of the traditional bamboo flute.
