Description

Technical Field

[0001] The present application belongs to the technical field of musical instruments, and in particular relates to a recorder. Background Art

[0002] The recorder, also known as the flute, is a wind instrument whose sound is produced by the airflow vibrating in the tube. When a player plays the recorder, the player needs to blow air into the mouth of the recorder so that the air blown by the player enters the tube, generating resonance vibrations to produce beautiful sounds.

[0003] However, when a player plays the recorder, due to the temperature difference between the air blown by the player and the recorder, the air blown by the player is easily liquefied into water droplets in the mouthpiece. As the playing time increases, more and more water droplets are in the mouthpiece, thus affecting the sound of the recorder. This problem is more obvious in cold weather.

[0004] In order to ensure that the recorder can produce beautiful sounds, the player usually needs to turn the mouthpiece upside down after playing for a while, and then shake the recorder to shake out the water drops in the mouthpiece; however, this operation affects the player's experience of use.

At the same time, when the heating element 1 is working, the heating element 1 heats the heating plane 213. Since the heating plane 213 constitutes part of the channel wall of the air inlet channel, the heating element 1 and the air inlet channel avoid each other, so as to avoid the situation where the heating element 1 affects the beautiful sound of the recorder, and improve the use experience of the performer.

[0054] In a preferred embodiment, the accommodating cavity has an opening at the end of the mouthpiece away from the flute tail, so that the assembler can assemble the mounting shell 2 into the mouthpiece through the opening, thereby improving the assembly efficiency of the recorder and reducing the production cost of the recorder.

Since the installation shell 2 includes the first shell 21 and the second shell 22, and the installation cavity 3 is formed between the first shell 21 and the second shell 22, the effect of facilitating the installation of the heating element 1 is achieved.

[0059] Furthermore, one of the first shell 21 and the second shell 22 is provided with a connecting hole 221, and the other of the two is provided with a connecting column 211 that is plugged into and matched with the connecting hole 221, so that the connecting column 211 and the connecting hole 221 are plugged into and matched with each other, thereby realizing a detachable connection between the first shell 21 and the second shell 22, thereby increasing the connection stability of the first shell 21 and the second shell 22, and further increasing the stability of the heating element 1.

[0060] Preferably, the connecting column 211 is disposed on the first shell 21 , and the connecting hole 221 is disposed on the second shell 22 .

[0064] Implementation Example 2: In this implementation example, the heating element 1 includes a circuit board 12, a heating plate 11 electrically connected to the circuit board 12, and a battery for supplying power to the heating element 1.

[0065] When the recorder is played, the battery supplies power to the heating plate 11 so that the heating plate 11 heats the air inlet passage. In this process, the need for a power cord to be directly connected to the recorder is avoided, so that the playing scene of the recorder is not restricted, thereby increasing the flexibility of the recorder.

The heating plate 11 is provided in the first cavity 31, and the circuit board 12 is provided in the second cavity 32, so that the heating plate 11 and the circuit board 12 are separated by the partition 321, thereby avoiding the circuit board 12 from having a high temperature, so that the circuit board 12 can work at a relatively low temperature, thereby increasing the service life of the circuit board 12, reducing the failure rate of the recorder, and improving the use experience of the performer.

[0071] Specifically, the first cavity 31 is located in the first shell 21, the second cavity 32 is located in the second shell 22, and the partition 321 is located in the second shell 22.
