Abstract
Provided is a demonstrator for Erhu teaching, relating to the technical field of music teaching aids. The demonstrator comprises a casing, an Erhu stand, a pull rod, a connecting rod, a rotary rod, a stepping motor and a motor base, wherein the Erhu stand is mounted on the top surface of the casing, the motor seat is mounted at the bottom surface of the casing, the rotary rod is connected with the stepping motor, one end of the connecting rod is hinged to the rotary rod, the other end of the connecting rod is hinged to the pull rod, the pull rod penetrates through a sliding hole in the top surface of the casing, and the included angle between the sliding hole and the top surface is 45 degree. The demonstrator has the advantages of being simple, novel and unique in structure, capable of automatically demonstrating playing of the Erhu, and being educational and interesting.
Description
Technical field
The utility model relates to a kind of music teaching aid technical field, relate in particular to a kind of apparatus for demonstrating for urheen teaching.
Background technology
When urheen is imparted knowledge to students, for the first song of every professor one, all need teacher to pull urheen, repeatedly pull same first song, teachers work intensity is larger, easily produces tiredly, occurs that detonieren or tonequality are variant, gives the teaching of music teachers, brings very large trouble.
Utility model content
In order to address the above problem, technical solution adopted in the utility model is: a kind of apparatus for demonstrating for urheen teaching, it is characterized in that, and comprise casing, qin frame, pull bar, connecting rod, dwang, stepper motor and motor cabinet; Described qin frame is arranged on the upper end face of described casing, described motor cabinet is arranged on the bottom surface in described casing, described dwang is connected with described stepper motor, one end of described connecting rod and described dwang are hinged, the other end of described connecting rod and described pull bar are hinged, and described pull bar is by the sliding eye of end face on described casing; The upper end face of described casing has the sliding eye that becomes 45 degree to tilt with upper top surface plane.
The beneficial effects of the utility model are: simple in structure, novel unique, and can demonstrate automatically drawing of urheen and play, existing educational, interesting again, effectively alleviate user's labour intensity.
Accompanying drawing explanation
Fig. 1 is perspective view of the present utility model.
Fig. 2 is the perspective view that removes cabinet front plate and right panel of the present utility model.
Fig. 3 is the front view that removes cabinet front plate and right panel of the present utility model.
In figure: 1 casing, 2 qin framves, 3 pull bars, 4 connecting rods, 5 dwangs, 6 stepper motors, 7 motor cabinets.
Embodiment
For clearly demonstrating the technical characterstic of this programme, below by an embodiment, and in conjunction with its accompanying drawing, this programme is set forth.
If accompanying drawing 1 is to as shown in accompanying drawing 3, in order to address the above problem, technical solution adopted in the utility model is: a kind of apparatus for demonstrating for urheen teaching, it is characterized in that, and comprise casing 1, qin frame 2, pull bar 3, connecting rod 4, dwang 5, stepper motor 6 and motor cabinet 7; Described qin frame 2 is arranged on the upper end face of described casing 1, described motor cabinet 7 is arranged on the bottom surface in described casing 1, described dwang 5 is connected with described stepper motor 6, one end of described connecting rod 4 and described dwang 5 are hinged, the other end of described connecting rod 4 and described pull bar 3 are hinged, and described pull bar 3 is by the sliding eye of end face on described casing 1; The upper end face of described casing 1 has the sliding eye that becomes 45 degree to tilt with upper top surface plane.
During teaching, first bow is fixed on qin frame 2, qin bar is connected with pull bar 3, and stepper motor 6 rotates, and drives dwang 5 to rotate, and then connecting rod 4 pulls pull bar 3 to do linear reciprocating motion, thereby makes qin bar and bow relative motion, sends vocal music; By song is programmed, the rotation speed of programmed instruction control step motor 6 and the angle of rotation, realize the frequency that qin bar pulls and pull displacement, thereby sending corresponding vocal music.
Except the technical characterictic described in instructions, be the known technology of those skilled in the art.
