Intelligent piano device

Abstract

The invention provides an intelligent piano device which structurally comprises a power supply groove, a case, a sound production end, knocking keys and a supporting frame, the power supply groove is embedded in the side edge of the case and is electrically connected, the sound production end is installed at the upper end of the case, and the knocking keys are positioned below the sound production end; after the loudspeaker at the sound production end is improved, the telescopic rod and the expansion ring can be controlled through the rotating body, the contact area between the sound outlet hole and air is adjusted and controlled, then the effect of controlling the volume is achieved, meanwhile, the vibration shaft in the sound outlet hole can be positioned in the empty groove under the clamping of the positioning base, and the discharging effect of relieving the volume is achieved; the corresponding tone effect can be improved to achieve a low effect according to the vibration effect of the beginner along with the volume, so that the phenomenon that the beginner affects external things in the learning process can be effectively solved; and moreover, the tone discharge effect can be effectively improved, the learning progress of a beginner is increased, and the confidence of the beginner is increased.

Description

technical field [0001] The invention relates to the field of pianos, in particular to an intelligent piano device. Background technique [0002] The piano is a keyboard instrument in Western classical music, known as the "King of Musical Instruments". The keyboard on the front side of the piano and the strings on the back end can be used to cooperate with each other to perform music performance and sound effects, resulting in intelligent prompts through the piano. Under the effect, it is convenient to assist beginners in fingering practice, thereby improving the learning efficiency of beginners on the piano, and preventing beginners from being indistinguishable from the formation of many buttons; In summary, the inventors found that the existing intelligent piano device mainly has the following defects: when the intelligent piano device is in use, it can send out the sound of the keys being knocked through the speakers on both sides, because the speakers on both sides of th...

Problems solved by technology

In summary, the inventors found that the existing intelligent piano device mainly has the following defects: when the intelligent piano device is in use, it can send out the sound of the keys being knocked through the speakers on both sides, because the speakers on both sides of the piano are both With a specific diameter and the state of being exposed and in the air, after a long time for beginners to learn to play, the timbre produced is relatively lacking in the corresponding degree of softness, so that it will directly affect the external things and produce a greater sound interference
