The invention discloses a tone adjustment demonstrator which comprises a bottom plate, a current controller is fixedly installed on the right side of the front portion of the upper side surface of thebottom plate through bolts, a storage battery is installed on the current controller, a master control switch is arranged in front of the storage battery, and a damping base is arranged on the left side of the current controller. A groove is formed in the middle of the upper side surface of the damping base, a mounting plate is arranged at an upper end opening of the groove, a driving motor is fixed to the upper side surface of the mounting plate through bolts, a rotating shaft is connected to the output end of the driving motor, and the end, away from the driving motor, of the rotating shaftis fixedly sleeved with a gear through welding; and a fixing plate is arranged at the rear side of the current controller, a supporting sheet is fixed to the right end of the fixing plate through welding, and an aluminum sheet is fixed to the left side of the upper end of the supporting sheet through welding. The tone adjustment demonstrator is simple in structure, easy to manufacture, low in cost, small in size, convenient to carry and capable of clearly sensing tone changes.
Description
technical field [0001] The invention relates to the technical field of tone adjustment demonstrators, in particular to a tone adjustment demonstrator. Background technique [0002] Pitch is the high or low frequency of the sound, which is mainly determined by the frequency of the sound and also related to the intensity of the sound; the key to adjusting the pitch is to adjust the vibration frequency of the sound-emitting object. In music teaching, teachers often teach students the knowledge of pitch. [0003] Today's music teachers often use musical instruments as demonstrations to teach the principles of pitch when teaching pitch courses. However, neither percussion instruments nor plucked instruments can clearly show the relationship between pitch and the speed of vibration of objects. Contents of the invention [0004] The purpose of the present invention is to provide a pitch adjustment demonstrator to solve the problems raised in the background art above. [0005] I...
