Description
Technical field
The present invention relates to support frame structure, be specifically related to be used for the bracing frame of the auxiliary guiding device of support piano.
Background technology
Along with the progress of society, cultural life more and more receives people's attention.For example, increasing people study plays the piano, mellotron etc.When study is played, to understand the qin spectrum, find correct key, and when playing existing beat, also need consider beat, play smoothly, these three kinds of processing must be carried out simultaneously, and do not have the people through long-time training not accomplish.The beginner often is unfamiliar with qin spectrum, key, can not control rhythm, also can not get timely correction when makeing mistakes, and the process that causes playing is dry as dust, lacks efficient, also is difficult to realize the enjoyment of the interesting to listen to music of own ejection.
In view of this, the applicant has invented out a kind of musical instrument and has played guiding device (see application number for details be 201120249007.9 utility model patent).During use, it is placed on the key, and corresponding key is pressed in the indication that the beginner only need follow on the light-emitting diode display panel, just can play out smooth music.
But deviation appears in putting position that above-mentioned musical instrument is played guiding device easily, thereby misleads playing of beginner.
Summary of the invention
The objective of the invention is to propose a kind of key support formula bracing frame, it can solve existing when playing guiding device and being placed on the key, occurs the problem of deviation easily.
In order to achieve the above object, the technical scheme that the present invention adopted is following:
Key support formula bracing frame, it comprises that one is used for the support flat board that support is played the housing of guiding device; The dull and stereotyped end face of support extends upward two support bars that are used to support the back side of shell of playing guiding device, and the locating convex block that can be complementary with the detent of the housing bottom of playing guiding device; Two support bars lay respectively at the dull and stereotyped left and right sides of support, and locating convex block is between two support bars; The dull and stereotyped bottom surface of support is extended with positioning wedged block downwards, and three black keys of the width of positioning wedged block and a key and the gap between two black keys are complementary; The dull and stereotyped bottom surface of support contacts with the black key of key.
In order to make support more stable, the cross section of support bar is a triangle, and the angle of the hypotenuse of support bar and support flat board is the obtuse angle.The thickness of support flat board reduces along the hypotenuse of dull and stereotyped front side to the support bar of support gradually.
In order to strengthen the dull and stereotyped intensity of support, the dull and stereotyped end face of support has also extended upward reinforcement, and two support bars connect through reinforcement.
In order to eliminate the noise that key when bounce-back produces with the dull and stereotyped collision of support, the dull and stereotyped bottom surface of support also is coated with a noise reduction layer, and noise reduction layer employing quieter material or playback material form, for example soft material.
Concrete, key support formula bracing frame with play a kind of implementation method that guiding device combines and be: single-chip microcomputer is installed, the storage card that links to each other with single-chip microcomputer, selection control module and light-emitting diode display panel in the said housing of playing guiding device; Housing is a rectangular shape; Some light-emitting diode group on the light-emitting diode display panel are corresponding with key.
Concrete, key support formula bracing frame with play the another kind of implementation method that guiding device combines and be: in the said housing of playing guiding device light-emitting diode display panel is installed; Housing is a rectangular shape; Some light-emitting diode group on the light-emitting diode display panel are corresponding with key; Said single-chip microcomputer, the storage card of playing guiding device is installed on the support flat board; Selection control module, storage card, the light-emitting diode display panel of playing guiding device electrically connect with single-chip microcomputer respectively, select control module to be positioned at the hull outside that support is dull and stereotyped and play guiding device.Install for ease, the dull and stereotyped end face of support has also extended upward a chip mounting box, and single-chip microcomputer, the storage card of playing guiding device all are positioned at the chip mounting box; The chip mounting box is provided with contact flat spring, and contact flat spring and single-chip microcomputer electrically connect, and the back side of shell of playing guiding device is provided with the contact contact, and said contact contact and light-emitting diode display panel electrically connect; When the detent of the housing of playing guiding device and locating convex block were pegged graft, the contact contact was connected with contact flat spring.In order to expand the function of playing guiding device, the dull and stereotyped end face of support has also extended upward at least one functional module slot mouth, in the said functional module slot mouth circuit contact is installed, and circuit contact and single-chip microcomputer electrically connect; A functional module socket and a functional module are inserted body and are pegged graft, and the electrical contact that functional module is inserted body is connected with circuit contact.It is memory card or power module or player that said functional module is inserted body.
The present invention has following beneficial effect:
Cooperatively interacting of locating convex block and positioning wedged block; Can realize playing the light-emitting diode display panel and the accurate contraposition of key of guiding device; Eliminated the offset issue of prior art; Positioning wedged block also has the dull and stereotyped effect of sliding of the support of preventing, locating convex block prevents to play the effect that the housing of guiding device slides.And the support flat board is pressed on the black key of all keys, disperseed gravity, avoided black key to be forced down; Noise reduction layer on the support planar bottom surface can prevent effectively that the player from pressing black key behind the black key and upspringing and knock the dull and stereotyped and unnecessary sound that sends of support.
