Description

Board for teaching mathematics

Technical field

This utility model is related to mathematics teaching aid technical field, and in particular to board for teaching mathematics.

Background technology

At present, Jing normal needs during mathematical education are mapped on blackboard and explain demonstration, as the space of blackboard has Limit, and need to be erased after clerical error to write again, it is very loaded down with trivial details, and the inadequate vivid and interesting of teaching process.

Utility model content

The purpose of this utility model is primarily to solve above-mentioned technical problem, and provide board for teaching mathematics.

This utility model is included substrate, one group of Magnet, touch keypad, is known based on the main control board of microchip, voice Other module, mike and LCDs, the front of the substrate is provided with touch keypad mounting groove, in mounting circuit boards Chamber, LCDs mounting groove, mike mounting groove and speaker mounting groove, the back side of substrate are provided with one group of magnet mounting groove, One group of Magnet is respectively and fixedly installed at one group of magnet mounting groove of substrate back, and the touch keypad is just being arranged on substrate At the touch keypad mounting groove in face, the main control board and sound identification module based on microchip is separately mounted to substrate Inner chamber at, at the mike mounting groove installed in substrate of the mike, the LCDs be arranged on substrate liquid At crystal display screen mounting groove, the touch keypad, sound identification module, mike and LCDs with based on microchip Main control board is electrically connected.

Also speaker, the speaker are arranged at the speaker mounting groove of substrate, and speaker be based on minicore The main control board electrical connection of piece.

The substrate adopts aluminium profile.

Also lithium battery group, the lithium battery group are arranged at the inner chamber of substrate, and respectively each electricity piece is powered.

This utility model advantage is：Popularization of the present utility model can provide board for teaching mathematics, and simple structure directly can be inhaled It is attached on irony blackboard, conveniently carries out input or phonetic entry first, mitigate mathematical education process sassafras blackboard workload, make religion More vivid and interesting is learned, with good practical value.

Specific embodiment

Below in conjunction with the accompanying drawings this utility model is described further.

As shown in Figure 1, 2, 3, this utility model include substrate 1, one group of Magnet 2, touch keypad 3, based on microchip Main control board 4, sound identification module 5, mike 6 and LCDs 7, the front of the substrate 1 are provided with touch keypad peace Tankage, the inner chamber for mounting circuit boards, LCDs mounting groove, mike mounting groove and speaker mounting groove, substrate 1 The back side is provided with one group of magnet mounting groove, and one group of Magnet 2 is respectively and fixedly installed to one group of magnet mounting groove at 1 back side of substrate Place, the touch keypad 3 are arranged at 1 positive touch keypad mounting groove of substrate, the governor circuit based on microchip Plate 4 and sound identification module 5 are separately mounted at the inner chamber of substrate 1, and the mike installed in substrate 1 of the mike 6 is pacified At tankage, the LCDs 7 are arranged at the LCDs mounting groove of substrate 1, the touch keypad 3, speech recognition Module 5, mike 6 and LCDs 7 are electrically connected with the main control board 4 based on microchip.

Also speaker 8, the speaker 8 are arranged at the speaker mounting groove of substrate 1, and speaker 8 be based on it is micro- The main control board 4 of cake core is electrically connected.

The substrate 1 adopts aluminium profile.

Also lithium battery group 9, the lithium battery group 9 are arranged at the inner chamber of substrate 1, and respectively each electricity piece is powered.

Working method and principle：One group of Magnet 2 of the present utility model is adsorbed on irony blackboard during use, if adopted Handwriting input, only need to be write with writing pencil on touch keypad 3, and the hand-written information that touch keypad 3 is obtained passes through base It is displayed in LCDs 7 in the main control board 4 of microchip, if adopting phonetic entry, teacher's will directly need Information to be write is read aloud with mandarin, and mike 6 is by the transmission of speech information for receiving to sound identification module 5, voice The transmission of speech information for being recognized to the main control board 4 based on microchip, and is eventually displayed in liquid crystal by identification module 5 In display screen 7, the effect of speaker 8 is that math computation result is carried out massage voice reading.

Embodiment of above is merely to illustrate this utility model, and is not limitation of the utility model, relevant technology neck The those of ordinary skill in domain, in the case of without departing from spirit and scope of the present utility model, can also make a variety of changes and Modification, therefore the technical scheme of all equivalents falls within category of the present utility model, scope of patent protection of the present utility model should It is defined by the claims.
