Specific embodiment

Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete Site preparation is described, it is clear that described embodiment is only a part of embodiment of the invention, rather than whole embodiments.It is based on Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under the premise of creative work is not made Embodiment, belongs to the scope of protection of the invention.

Fig. 1-6 are referred to, the present invention provides a kind of technical scheme：

A kind of English Listening and Speaking exerciser, including housing, hear receiving unit, hear processing unit and fixed cell, housing Including base plate 1 and upper lid 2, base plate 1 and upper lid 2 use light plastic, and intensity is enough and wears very light, base plate 1 Fluted 4 are opened up, groove 4 is used for installing mainboard 5, and base plate 1 offers mounting hole 1 in the surrounding of groove 4, and the middle part of upper lid 2 is passed through Open up and be provided with through hole 21, through hole 21 is used for coordinating touch-screen 13, touch-screen 13 is conveniently operable by a user, the inner side of through hole 21 Mounting groove 22 is offered in wall, correspondence mounting hole 1 offers mounting hole 2 23, mounting hole 1 and mounting hole two in upper lid 2 Grafting is coordinated by screw 25 between 23, the effect of fixed base plate 1 and upper lid 2 is played, so as to internal mainboard 5 and mainboard 5 The thing of upper setting plays a protective role, and upper lid 2 is respectively and fixedly provided with shatter-resistant post 24 away from four turnings of the side surface of base plate 1 one can The exerciser is effectively prevented when experience is beaten with external force collision, directly upper lid 2 and touch-screen 13 will not be caused to damage.

Hear that receiving unit includes connection strap 3, microphone 8, battery 9 and earphone 11, connection strap 3 is fixed with the side wall of base plate 1 Connection so that keep being relatively fixed between connection strap 3 and base plate 1, three article putting grooves 7 are offered in connection strap 3, article putting groove 7 is pressed It is configured according to the size of microphone 8, battery 9 and earphone 11 so that more stablize when compact conformation and placement, three are put Microphone 8, battery 9 and earphone 11 are disposed with thing groove 7, the side of article putting groove 7 for being provided with earphone 11 offers and connects therewith Logical line outlet groove 12 so that earphone 11 after use is taken out, closed by groove lid 31, and the line of earphone 11 is drawn by line outlet groove 12 so that Groove lid 31 will not cause extrusion damage to the line of earphone 11, largely effective.

Connection strap 3 is embedded with iron block 71 in the side of each article putting groove 7, and iron block 71 is embedded in inside connection strap 3, sets Have in the article putting groove 7 of earphone 11 and be further fixed on wrapping post 10, the height of wrapping post 10 is less than the depth of article putting groove 7, and wrapping post 10 is used To wind the line of earphone 11, prevent the distribution in article putting groove 7 of the line of earphone 11 mixed and disorderly, also have an impact to earphone 11 service life itself, Groove lid 31 is provided with each opening of article putting groove 7, groove lid 31 is exactly to be used for protecting the part in article putting groove 7, dust-proof Anti-collision, groove lid 31 is hinged by hinge 32 away from the one end of iron block 71 with connection strap 3, and one end is hinged, and can make the groove lid 31 will not be Because placement location causes to lose farther out after opening, groove lid 31 is being fixed with magnetic stripe 33 near the one end of iron block 71, and magnetic stripe 33 is just It is the effect for reaching closure article putting groove 7 using magnetic in order to coordinate the use of iron block 71.

Hear that processing unit includes mainboard 5 and the single-chip microcomputer 51, memory 52, the hard disk 53, modulus that are fixed on mainboard 5 Converter 54, digital analog converter 55, amplifier 56 and touch-screen 13, mainboard 5 are fixed in groove 4, groove 4 and each article putting groove Equal insertion offers string holes 6 between 7, and string holes 6 plays a part of the part on convenient connection mainboard 5 and the part in connection strap 3, Touch-screen 13 is inserted in mounting groove 22, and mounting groove 22 plays fixed effect, and touch-screen 13 and single-chip microcomputer to touch-screen 13 51 are electrically connected with, and are communicated by communications protocol between touch-screen 13 and single-chip microcomputer 51, and are set by touch-screen 13 Graphic button play to the control of the various functions of single-chip microcomputer 51, graphic button includes playing, upper one, next sentence, pause And shutdown.

The analog-digital converter 54 and digital analog converter 55 are connected on the different I/O pins of single-chip microcomputer 51, modulus Converter 54 selects AD976 types, digital analog converter 55 to select DAC0832 types, be combined with 8031 type single-chip microcomputers, can be very good Directly changed into data signal and analog signal, the one end of the memory 52 is connected to single-chip microcomputer 51 and the other end is connected to firmly Disk 53, memory 52 selects built-in storage, analog-digital converter 54 to be connected on microphone 8 by corresponding string holes 6 so that monolithic Machine 51 receive from touch-screen 13 to signal after, after speech data is processed by analog-digital converter 54, storage exist In hard disk 53, digital analog converter 55 is connected with amplifier 56, and amplifier 56 is connected on earphone 11 by corresponding string holes 6, made Single-chip microcomputer 51 is obtained when other command signals of touch-screen 13 are received, speech data is extracted from hard disk 53 by memory 52, After via the conversion process of digital analog converter 55, effect is amplified by amplifier 56, is played out from earphone 11, realize record Sound and the circulatory function played.

Amplifier 56 is together distributed in the side of battery 9 with earphone 11, and analog-digital converter 54 is together distributed in microphone 8 The opposite side of battery, because amplifier 56 is connected with earphone 11, analog-digital converter 54 is connected with microphone 8, so homonymy sets Put so that the wiring between them will not occur confusion, produce the situation of coiling, it is also possible to shorten the length of wiring well, Material is saved, single-chip microcomputer 51, memory 52, touch-screen 13 are electrically connected at battery 9 by corresponding string holes 6, and battery 9 is set In connection strap 3, person more convenient to use changes.

Fixed cell includes that the bonding for being fixed on the bottom wall of base plate 1 covers 14 and fixing band 15, and bonding set 14 is matched somebody with somebody with fixing band 15 Close, and the holding relative with base plate 1 of bonding set 14 is fixed, and VELCRO circle hair 1 is provided with bonding set 14, fixing band 15 is plugged In bonding set 14, fixing band 15 is provided with VELCRO seta 1, VELCRO circle hair with the VELCRO circle contact surface of hair 1 Pasted between one 141 and VELCRO seta 1, play bonding set 14 and be relatively fixed with fixing band 15, fixing band 15 Openend be respectively arranged with mutually paste coordinate VELCRO circle hair 2 152 and VELCRO seta 2 153, then by magic The relative bonding of patch circle hair 2 152 and VELCRO seta 2 153 so that fixing band 15 is more conveniently worn on the arm of user On, and conveniently remove, it is very convenient to use.

Although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with Understanding can carry out various changes, modification, replacement to these embodiments without departing from the principles and spirit of the present invention And modification, the scope of the present invention be defined by the appended.
