Fig. 1 is a schematic structural view of a percussion instrument embedded with a tone color adjusting device according to an embodiment of the present disclosure.
Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the invention, as detailed in the appended claims.
In view of the problem that the timbre of the existing percussion instrument is not adjustable, the embodiment firstly attempts to change the volume form of the effective sounding cavity so as to realize the continuous tone adjustment of the percussion instrument. Specifically, referring to fig. 1, the percussion instrument embedded with a sound color adjusting device provided in the present embodiment is mainly composed of a drum body 1, an upper drum surface 2, a sound color adjusting device 3, a lower drum surface 4, a displacement sensor and a controller 5, wherein the drum body 1 is cylindrical, a cavity penetrating through the upper end and the lower end is arranged inside the drum body 1, the upper drum surface 2 is arranged at the upper end port of the drum body 1 in a sealing manner, the sound color adjusting device 3 is arranged in the cavity of the drum body 1, the lower drum surface 4 is movably arranged in the drum body 1 and is parallel to the upper drum surface 2, the lower drum surface 4 is connected with the sound color adjusting device 3, the lower drum surface 4 can move up and down relative to the upper drum surface 2 under the driving of the sound color adjusting device 3, so that an effective sounding cavity formed by the lower drum surface 4, the drum body 1 and the upper drum surface 2 is subjected to volume change, the displacement sensor is installed on the lower drum surface 4, the displacement sensor is used for detecting the displacement of the lower drumhead 4, the output end of the displacement sensor is connected with the input end of the controller 5, the displacement sensor sends detected displacement information to the controller 5, the output end of the controller 5 is connected with the control end of the tone adjusting device 3, and the controller 5 controls the tone adjusting device 3 to carry out corresponding adjustment according to the tone requirement and the displacement information sent by the displacement sensor.
The percussion instrument that has tone adjusting device that it inlayed that this embodiment provided, during its use, can adjust through controller control tone adjusting device according to the tone quality needs of reality for drum head reciprocates relatively last drum head down, and then makes the volume of the effective sound production cavity that upper drum head, lower drum head and drum shell enclose change. As is well known, two factors affecting the change of timbre are: the volume and the shape of material and sound production cavity, and in the percussion instrument that this embodiment provided, on the unchangeable basis of material, under tone quality adjusting device's drive, can make the volume of sound production cavity change, and then make the tone quality take place corresponding change. Because the lower drum surface can continuously change the position relative to the upper drum surface under the driving of the tone adjusting device, the continuous tone adjustment is realized, the displacement detection of the lower drum surface can be realized through the arrangement of the displacement sensor, a control closed loop is formed, and the accurate control of the controller is realized.
The percussion instrument can be applied in two scenes respectively: one is a performance scenario; the other is a teaching scene. In the playing scene, because the percussion instruments with different timbres are needed to accompany in each piece of music, through the design of the percussion instruments, players of the percussion instruments do not need to strike alternately in different percussion instruments according to the design of the music, and during playing, the drumheads can move up and down correspondingly under the control of the controller according to the requirements of different periods of the music on the timbres, so that the players can strike different timbres on the same percussion instrument, and the requirements of the music are met. Apparently, the player only performs rhythmic striking, but actually, due to the position change of the lower drumhead, the player can play exciting music with different timbres according to music; in the teaching scene, students all have theoretical understanding to the tone quality in the music theory study, nevertheless can't have a audio-visual understanding to the tone quality all the time, through the design of above-mentioned percussion instrument, through controller control tone quality adjusting device for the relative lower drumhead of drumhead carries out continuous position change down, through strikeing the drumhead, can make the student directly perceived the continuous change of tone quality, deepens the understanding to the tone quality, has the meaning of imparting knowledge to students.
The structure of the tone color adjustment device 3 in the above embodiment can be variously selected, for example, by screw driving or the like, as long as the position adjustment of the lower drumhead can be achieved.
