Abstract

Disclosed is a desk-mat with a keyboard instrument composed of a mat member and a container box-body fixed vertically to a side thereof, wherein the mat member is provided as bottom ply with a cushion sheet made of resilient materials, on which an insulator sheet, a conductor sheet, and a keyboard printed sheet are laminated in that order and finally a transparent sheet is laid immediately thereon. The container box-body is provided with an IC member through which a speaker and conductors of the conductor sheet are connected, a jack to which a plug of a DC adapter connected to a power source is inserted and a switch for switching on and off the power circuit.

Description

The desk-mat that has keyboard instrument

The present invention relates to a kind of desk-mat that has keyboard instrument, particularly a kind ofly be used for being placed on various desk end faces, have the desk-mat of keyboard instrument, the pupil can be by it easily, practise music giocoso in themselves family.

This desk-mat that has contact-making switch formula keyboard instrument of prior art comprises transparent panel and the base part of being made by flexiplast, and base part comprises upper plate and the lower plate that is located under the described transparent panel.Wherein, upper plate be provided with its underpart be used to accommodate the following chamber of keyboard and be used at an upper portion thereof accommodate thin battery, Yang Sheng device and integrated circuit on the chamber, the keyboard that is contained in down in the chamber is connected in battery, loudspeaker and integrated circuit by lead.

The aforesaid common desk-mat volume that has a keyboard instrument is very poor, this is because thin speaker is constrained to a kind of " toy " or " amusement " type, make it be difficult to be used as the keyboard instrument of suitable purpose, in addition, because the electric power of flat baby battery is easy to consume at short notice, thereby be difficult to perform for a long time music, and usually to change battery be a trouble.In addition, because battery is little, this can not do greatly the size of keyboard itself, and keypad also is unsuitable for ear-training.

Therefore, the purpose of this invention is to provide a kind of desk-mat that has keyboard instrument, it is suitable for carrying out suitable music training most, and as the keyboard instrument long service life, volume is good, also is suitable for the pupil and writes as the desk pad.

According to the desk-mat that has keyboard instrument of the present invention, it comprises a rectangular gasket and is fixed on container box on the side of liner, described liner comprises that one is made by resilient material, pad as base plate, an insulating trip that is directly arranged on the described pad, one is combined with lead, be placed directly in the current-carrying plate on the insulating trip, one is printed on keyboard and is laminated to keyboard printed sheet on the current-carrying plate, and slide, see through it and can see the keyboard printed sheet, described container box is provided with the integrated circuit component that is connected in described conducting strip and the loudspeaker that is connected in integrated circuit component, and described container box is provided with also that at its sidepiece one is used to insert the socket of the DC adapter plug that is connected in household AC power and at the switch that is fixed between plug and the integrated circuit component on its surface.

Brief description of drawings:

Fig. 1 be layered on the desk end face according to the stereographic map that has the desk-mat of keyboard instrument of the present invention;

Fig. 2 is the planimetric map of desk-mat itself;

Fig. 3 is the sectional side elevation along A-A line among Fig. 2;

Fig. 4 is the sectional side elevation along B-B line among Fig. 2;

Fig. 5 is the planimetric map of conducting strip.

The contrast accompanying drawing describes preferred embodiment of the present invention in detail below.

Comprise rectangular gasket 3 and the container box 2 that is contained in 3 one sides of liner according to the desk-mat that has keyboard instrument of the present invention, as illustrated in fig. 1 and 2.Liner 3 is provided with pad 10 that a resilient material makes as base plate.Pad is coated with insulating trip 13, and conducting strip 14 contact laminatings that are combined with small diameter wire on it are on insulating trip 13.Insulating trip 13 and conducting strip 14 do not cover pad 10 fully, but just are limited to its middle body for economic consideration office's cloth, as shown in Figure 2.

With the random color printing keyboard 9 of needs, keyboard printed sheet 11 is laminated on the conducting strip 14 on keyboard printed sheet 11, and the lead 15 of conducting strip 14 is connected in the keyboard 9 of keyboard printed sheet 11.

Lamination slide 12 on the keyboard printed sheet 11, thereby can see keyboard 9 through pad surfaces.

Container box 2 vertically is fixed in the right side or the left side of liner 3, and the integrated circuit component 6 and the loudspeaker 7 that is connected in described integrated circuit component 6 of the lead 15 that is connected in conducting strip 14 are housed.One socket 8 be fixed on container box 2 the side its be used to insert the plug 17 of the DC adapter 18 that is connected in household AC power, and the desk-mat that has keyboard instrument can be connected in power supply, and a switch 5 that is used to connect and cuts off the electricity supply is contained in the surface of container box 2.In addition, container box 2 is provided with the tray 16 that holds pencil or ball pen etc. in its surperficial other parts.The desk that on behalf of the pupil, label 20 use is laid the desk-mat that has keyboard according to of the present invention thereon.As shown in Figure 1, be layered on according to desk-mat of the present invention on the end face of the desk that the pupil uses, can on liner 3, writing work under this condition.For example, in the situation of exercise keyboard instrument, in the socket 8 that the pupil can insert the plug 17 of DC adapter 18 on the side that is contained in container box 2, so that be connected in power supply by its lip-deep master cock 5, thereby electricity is connected, pass through then from the downward keypad 9 of the end face of slide 12, contact-making switch can make integrated circuit component 6 work, also makes loudspeaker 7 produce the volume that learning musics use.

In the desk-mat that has a keyboard instrument of the present invention, the pupil can not only resemble and write work the common mat applying, and also can carry out actual music training by keyboard operation.In addition, now large scale keyboard and supersound projector can be set in liner and container box respectively, so just can also be suitable for most carrying out the music training aptly for a long time as keyboard instrument.On the other hand, the pad that resilient material is made is as base plate, and insulating trip is set, thereby lead and conducting strip can obtain safe protection.In addition, the area of conducting strip is provided with less than liner, thus for the total length of the lead that is connected in integrated circuit component can much shorter, so just more economical.
