Description

Technical Field

[0001] The utility model relates to the technical field of musical instruments, in particular to an electric Hulusi. Background Art

[0002] As a new type of electric musical instrument, the electric Hulusi has gradually been widely used. However, the electric Hulusi also has at least the following disadvantages: First, it is not convenient to replace the main tube of the traditional electric Hulusi with other tunings. This is because the pickup of the traditional electric Hulusi is installed inside the upper end of the main tube. Therefore, if the tuning needs to be changed, the main tube needs to be replaced, and frequent plugging and unplugging of the main tube will cause poor contact. All these will lead to high costs for replacing the main tube. Second, when the fingers hit the main tube during playing, the pickup of the traditional electric Hulusi is installed inside the upper end of the main tube. The sound produced by the fingers hitting the sound holes of the main tube during playing will be transmitted through the main tube, amplified by the pickup and then transmitted out, which will cause a lot of unnecessary knocking noise during playing, which is not conducive to the musical effect of the performance; thirdly, the traditional electric Hulusi produces a "bang bang" sound when the airflow is played. This is because the traditional electric Hulusi picks up sound inside the main tube. When playing the sound (the airflow is short and powerful), the airflow passes through the reed and makes a "bang" sound, which is then amplified by the pickup, producing inevitable noise. Utility Model Content

[0032] Example 1

[0033] The embodiment of the present application shows an electric Hulusi, including a gourd 100, which has a hollow cavity 110, a gourd mouthpiece end 120, and an opening 130 opened at the bottom of the gourd; it also includes a sound tube assembly 200, which extends from the opening 130 of the gourd 100 into the hollow cavity 110; a sound pickup device 300 is provided between the sound tube assembly 200 and the inner wall of the gourd 100 for picking up sound; and the sound pickup device 300 is located in the hollow cavity 110; the sound pickup device 300 is electrically connected to an audio component 400, and the audio signal transmitted by the sound pickup device 300 is collected by the audio component 400, processed and transmitted, and the processed sound of the Hulusi is received by a receiver and transmitted to an audience by a sound amplification device.

[0034] In this embodiment, the gourd 100 can be a round gourd, a flat gourd, etc., and its shape is not limited; the middle of the gourd 100 is hollowed out to form a hollow cavity 110; the gourd mouthpiece end 120 is used for playing; the opening 130 at the bottom of the gourd facilitates the insertion of the sound tube assembly 200, and the sound tube assembly 200 is inserted into the hollow cavity 110 to cooperate with the airflow transmitted from the gourd mouthpiece end 120 to produce sound; the sound pickup device 300 is arranged between the sound tube assembly 200 and the inner wall of the gourd 100, which is different from the existing sound pickup device 300 installed on the sound tube assembly 200; the audio component 400 is used to collect the audio signal transmitted by the sound pickup device 300 and send it out after processing. The processed sound of the Hulusi is received by the receiver and transmitted to the audience by the sound amplification equipment.

[0035] The sound pickup device 300 is arranged between the sound tube assembly 200 and the inner wall of the gourd 100 to achieve the following effects: First, it is troublesome and costly to replace the main tube of the current Hulusi for other tunings. Since the sound pickup device 300 of the traditional electric Hulusi is installed in the tube, each main tube of the tuning must have a complete set of sound pickup devices (including pickups, connecting wires, signal pin contacts, etc.). There are as many as 12 tunings in total, which will greatly increase the purchase cost for customers. The embodiment of the present application makes it easy to replace the main tube by separating the sound pickup device 300 from the sound tube assembly 200; Second, the existing electric Hulusi Striking the pipe during performance creates noise. Because the sound is picked up inside the pipe, the sound produced by the performer striking the sound hole is conducted through the pipe body to the pickup device 300 and amplified, causing the music to appear as a percussive noise. Thirdly, the airflow sound of the spitting sound is amplified. In the prior art, because the sound is picked up inside the pipe, the short and forceful airflow during spitting produces a "bang-bang" sound as it passes through the reed. This sound is then picked up and amplified by the pickup, seriously affecting the performance. The present embodiment addresses this issue, making the sound of blowing cleaner and significantly reducing the "bang-bang" sound of striking the pipe body and spitting. This allows the main pipes of 12 tunings to be easily replaced on a single electric gourd, significantly reducing the cost of use.

[0036] Furthermore, the sound tube assembly 200 and the gourd 100 are detachably connected, so that the sound tube assembly 200 can be easily replaced.

[0037] In an optional embodiment, the sound tube assembly 200 includes a sound producing portion 210 , which is located in the hollow cavity 110 and corresponds to the sound pickup device 300 ; the sound pickup device 300 corresponds to the sound producing portion 210 so that the sound pickup device 300 can pick up sound from the sound producing portion 210 .

[0038] In an optional embodiment, the sound tube assembly 200 includes a main tube 220 and two auxiliary tubes 230 located on both sides of the main tube 220 ; optionally, the sounding part 210 is disposed on the main tube 220 .

[0039] In an optional embodiment, the sound-producing portion 210 is configured as a reed, and the airflow blowing from the mouthpiece end 120 of the gourd drives the reed to vibrate and thus produce sound.

[0040] In an optional embodiment, the sound pickup device 300 faces the sound producing part 210 and the two are arranged relative to each other; by ensuring that the sound pickup device 300 faces the sound producing part 210 and the two are arranged relative to each other, it is beneficial to the efficient use of sound; the spacing between the sound pickup device 300 and the sound producing part 210 can avoid affecting the sound of the sound producing part 210.
