Abstract
The utility model relates to the electronic organ technical field, and discloses an improved portable electronic organ. The utility model consists of an electronic organ mainframe and an electronic organ keyboard connected with the electronic organ mainframe. The electronic organ keyboard comprises a top cover made of soft materials and a bottom plate. Keys are printed on the surface of the top cover. A film-like upper circuit board and a lower circuit board are arranged between the top cover and the bottom plate. A printed circuit layer is respectively provided on the surfaces of the upper circuit board and the lower circuit board that correspond to each other. Protruding insulated strips and protruding insulating dots are also provided between the upper circuit board and the lower circuit board to prevent one printed circuit layer from contacting the other when no keys are pressed. Because protruding insulated strips are added to the original protruding insulated dots between the upper circuit board and the lower circuit board, the utility model resolves the phenomenon that the printed circuit layers contact each other by mistake due to the excessively small supporting area of the protruding insulated dots when no keys are pressed, and thus greatly improve the quality of the electronic organ product.
Description
Technical field:
The utility model relates to the mellotron technical field, especially relates to a kind of folding mellotron.
Background technology:
Mellotron is a kind of musical instrument common in the modern society, and it has advantage cheap, simple to operate and is liked by the people of each age group.Mellotron is made up of main frame and this two large divisions of keys and keyboard, but its keys and keyboard of initial mellotron is to be made by hard material, and volume is bigger, carries rather inconvenience.In order to address this problem, insider's development and Design has gone out the Foldable cellular mellotron.Its keys and keyboard of this mellotron comprises loam cake and the base plate of being made by flexible material, the surface of loam cake is printed on key, accompany upper layer circuit plate and lower floor's wiring board that film like can be reeled between loam cake and the base plate, have the printed wire layer respectively on the upper layer circuit plate side relative with the lower floor wiring board.When the user pushed the key of cap surface, the mellotron main frame came sounding by the closed situation that scans different switches.In order to prevent the contact and cause the mellotron malfunction when the pressurized not of printed wire layer between loam cake and the base plate, on loam cake or base plate, be provided with a plurality of point-like insulation projectioies.But people in use find, though the existence of point-like insulation projection has certain effect, but still are difficult to eliminate fully the situation of the printed wire layer mistake contact when pressurized not between loam cake and the base plate, and the quality of product still has much room for improvement.
The utility model content:
The purpose of this utility model is to provide at the weak point of prior art existence a kind of portable electronic qin of improvement, and it can farthest eliminate the situation of the printed wire layer mistake contact when being not pressed between loam cake and the lower cover.
For achieving the above object, the utility model is to be made of with the keys and keyboard that links to each other with the mellotron main frame the mellotron main frame, wherein, described keys and keyboard comprises loam cake and the base plate of being made by flexible material, the surface of loam cake is printed on key, accompany upper layer circuit plate and lower floor's wiring board of film like between loam cake and the base plate, have the printed wire layer respectively on the upper layer circuit plate side relative, also be provided with between described upper layer circuit plate and the lower floor's wiring board and prevent that strip insulation projection and point-like insulation that the printed wire layer contacts are protruding when pressurized not with the lower floor wiring board.
Described strip insulation projection takes shape on the lower surface of upper layer circuit plate, and point-like insulation projection then takes shape on the upper surface of lower floor's wiring board.
The lower surface of the upper surface of described upper layer circuit plate and lower floor's wiring board is respectively equipped with the electrostatic prevention net.
Described mellotron main frame is provided with sound selector channel socket.
The beneficial effects of the utility model are: owing to increased strip insulation projection on the point-like that is provided with between upper layer circuit plate and the lower floor's wiring board insulate protruding basis, can eliminate because of simple point-like insulation projection causes the situation of line layer mistake contact when being not pressed up and down because of Area of bearing is less than normal and take place, thereby improve the mellotron product quality greatly.Electrostatic prevention net on upper layer circuit plate and the lower floor's wiring board is provided with, and can prevent that the loam cake of upper layer circuit plate, lower floor's wiring board and the silica gel material made because of PET, static that the base plate friction produces from burning out the problem of IC and wiring board.And the sound selector channel interface on the main frame then can allow the consumer freely select the sound of each passage of mellotron, and carries out editing and processing in the software of input computer.
Description of drawings:
Below in conjunction with accompanying drawing the utility model is described further:
Accompanying drawing 1 is a schematic appearance of the present utility model;
Accompanying drawing 2 is the schematic cross-section of upper layer circuit plate of the present utility model;
Accompanying drawing 3 is the schematic cross-section of lower floor of the present utility model wiring board
Accompanying drawing 4 is a global sections synoptic diagram of the present utility model;
Accompanying drawing 5 is the circuit theory diagrams of sound selector channel.
Embodiment:
The following stated only is preferred embodiment of the present utility model, does not therefore limit protection domain of the present utility model.
See shown in the accompanying drawing 1: the utility model is to be made of with the keys and keyboard 20 that links to each other with mellotron main frame 10 mellotron main frame 10; Mellotron main frame 10 is provided with switch, pilot lamp and loudspeaker etc.
See that accompanying drawing 2 is to shown in the accompanying drawing 4: keys and keyboard 20 comprises loam cake 21 and the base plate of being made by flexible material (as rubber, silica gel, flexiplast etc.) 22, and the surface of loam cake 21 is printed on key 211, plays for the user; Accompany upper layer circuit plate 23 and lower floor's wiring board 24 that the PET film is made between loam cake 21 and the base plate 22, upper layer circuit plate 23 and lower floor's wiring board 24 can be reeled with loam cake 21 and base plate 22, carry to make things convenient for the user.Have printed wire layer 231,241 respectively on the relative side of upper layer circuit plate 23 and lower floor wiring board 24, when the user pushed key 211, the corresponding contact on the printed wire layer 231 and 241 was connected, and mellotron gets final product sounding.For preventing that printed wire layer 231 from contacting when the pressurized not with 241, and make mellotron mistake sounding, also be provided with strip insulation projection 232 and point-like insulation projection 242 between upper layer circuit plate 23 and lower floor's wiring board 24, the height of strip insulation projection 232 and point-like insulation projection 242 is higher than printed wire layer 231,241 respectively.Make for convenient, strip insulation projection 232 is shaped on the lower surface of upper layer circuit plate 23, and point-like insulation projection 242 then is shaped on the upper surface of lower floor's wiring board 24.
