The specific implementation process is as follows:

in the course of teaching in a classroom, the performance information of each student in the classroom is sent to a teaching terminal through an acquisition module of a student terminal on the desk 1, for example, the voice, the image and the like of the student are acquired, and the performance information is acquired by a control module and sent to the teaching terminal through a communication module; the performance information is received by a receiving and sending module on the teaching terminal, meanwhile, the voice information is collected by the voice module, the processing module identifies the teaching state information from the voice information and selects the preset information according to the teaching state information, the processing module judges the performance information which can be the face-down sleeping, speaking or playing mobile phone identified from the image, when the performance information is judged to have the preset information, the processing module sends the voice information collected by the voice module and taught by the teacher to the student terminal, the playing module 4 directly plays the voice information of the teacher to a student, the range of sound transmission is limited by the area enclosed by the directional cover plate 2 and the movable cover plate 3, meanwhile, the rotating mechanism 12 drives the base 17 to rotate, the press rod 7 moves along the first chute 5 and the second chute 6, when the press rod 7 slides to the movable cover plate 3, is tilted due to the downward pressure of the pressing rod 7.

Compared with the existing method of detecting the performance of the students by using software and then controlling the volume of the increased sound to remind the students, the scheme of the first embodiment does not need to increase the volume of the sound, only needs to transmit the teaching sound to the students, and does not interfere with the students in the whole classroom; compared with the existing earphone for each student, the scheme of the first embodiment does not need each student to take, put down or adjust the volume of the device, and the problem that the device is easy to fall down or damage is solved; compared with the prior art that one sound amplifying device is used for the whole teacher, the first embodiment has the advantages that when the students show the preset information, the preset information is transmitted to the single students, so that too many students cannot be influenced, and internal parts and components cannot be damaged due to the fact that the sound of sound amplifying equipment is increased; this embodiment one lets sound increase propagation range intermittently, force the student to listen the speech information that the teacher gave lessons, also can let adjacent student hear simultaneously, thereby mention next door student's attention, from mentioning high certain degree's the ability of supervising each other, mode through improving student's attention promotes student's learning effect, because elastic segment 8 is initial in bending state, can perk start cover plate 3 when depression bar 7 gets into second spout 6, supply sound to expand and scatter, need not to set up power alone, more save, first pressure spring 11 can let depression bar 7 reset, guide rail 9 can carry on spacingly to depression bar 7.

Example two

The difference from the first embodiment is that, as shown in fig. 3, the desk further includes a lifting plate located on the desk 1, a groove for accommodating the lifting plate is formed in the desk 1, the playing module 4 is installed on the lifting plate, a sensing unit 15 for detecting a pressure value is installed on the lifting plate, the sensing unit 15 can be an existing pressure sensor, for example, a small pressure sensor of L10EM type, a mounting groove for accommodating the sensing unit 15 is formed in the lifting plate, a pressing plate 14 capable of moving up and down is placed in the mounting groove, the pressing plate 14 is located above the sensing unit 15, a second pressure spring 16 is clamped between the pressing plate 14 and the mounting groove, an elastic membrane 13 is bonded on a notch of the mounting groove, a lifting mechanism is arranged between the lifting plate and the desk 1, the control module obtains the pressure value for judgment, and when the pressure value is greater than a preset value, the control module controls the lifting; the lifting mechanism is a hydraulic cylinder, the control module controls the hydraulic cylinder to start to drive the lifting plate to lift, and the control module controls the hydraulic cylinder to drive the lifting plate to lower and reset when the pressure value is smaller than a preset value.

When the student sleeps on desk 1, detect the pressure value by induction element 15 and send to control module, the pressure value is greater than the default, control lifting mechanism drives the lifting board and risees during letting control module, when detecting the student and sleeping promptly, control module control pneumatic cylinder starts, let the student sleep on desk 1 on lying prone, it can rise the position of broadcast module 4 to lift the board simultaneously, let the sound propagation position rise, let teacher or student on every side notice the student of this sleep, in order to mention this student's of sleeping attention, in order to prevent the student to continue to sleep, moreover, the steam generator is simple in structure, and convenient operation.

EXAMPLE III

The difference from the first embodiment is that, as shown in fig. 4, the base 17 is hinged on the output shaft of the rotating mechanism 12 through a hinge plate, the hinge plate includes a first stator plate 20 and a second stator plate 18, the first stator plate 20 is welded on the end of the base 17, the second stator plate 18 is welded on the output shaft of the rotating mechanism 12, the first stator plate 20 and the second stator plate 18 are hinged through a damping rotating shaft 19 arranged vertically, a serrated soft sound-insulating plate is bonded between the directional cover plate 2 and the movable cover plate 3, the soft sound-insulating plate can be made of plastic, and the soft sound-insulating plate can add a little extra sound and improve the directionality of sound transmission.

When the performance information of the student is detected to be preset information, and the rotating mechanism drives the compression bar 7 to move along the second sliding groove 6, because the shape of the inner bottom surface of the second chute 6 and the base 17 are hinged on the output shaft of the rotating mechanism 12, the pressure lever 7 can resist the base 17 to swing to one side due to friction force, the directional cover plate 2 and the movable cover plate 3 are encircled to form a horn-shaped area facing to the adjacent students, the teaching sound of the teacher is transmitted to the adjacent students, the base 17 drives the directional cover plate 2 and the movable cover plate 3 to change the space position, and the extra sound added by the soft sound-proof sheet makes the teaching sound heard by the adjacent students more realistic, and the students beside the student can be reminded of the preset information students by noticing the small difference, and the base 17 is hinged with the rotating mechanism 12, so that the students can actively break the base 17 to reset when the performance information of the students is judged to be the preset information by mistake.

The foregoing is merely an example of the present invention and common general knowledge of known specific structures and features of the embodiments is not described herein in any greater detail. It should be noted that, for those skilled in the art, without departing from the structure of the present invention, several changes and modifications can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicability of the patent. The scope of the claims of the present application shall be determined by the contents of the claims, and the description of the embodiments and the like in the specification shall be used to explain the contents of the claims.
