Electronic information device for teaching

[0033] see Figure 1-Figure 6, the present invention provides an electronic information device for teaching, the structure of which includes: a soft rubber sealing cover 1, a sound transmission shock tube seat 2, a literal translation frequency conversion disk frame 3, an integrated circuit slot 4, a rubber-coated cushion seat 5, an ear canal buckle Rod 6, power distribution wire 7, the literal translation frequency conversion disk frame 3 is nested on the front side of the integrated circuit slot 4 and is on the same horizontal plane, the soft rubber sealing cover 1 is buckled together with the sound transmission and vibration tube seat 2 and The shaft centers are collinear, the sound transmission and vibration tube seat 2 is inserted in the lower left corner of the literal translation frequency conversion disk frame 3 and the integrated circuit slot 4 and are perpendicular to each other, and the rubber-coated seat 5 is nested in the right rear of the integrated circuit slot 4 s

[0040] see Figure 1-Figure 6 , the present invention provides a kind of electronic information device for teaching, other aspects are the same as Embodiment 1, the difference is:

[0041] see figure 2 , the scroll loudspeaker 3H is composed of a scroll ring frame 3H1, an aluminum foil tremolo strip 3H2, and a rotary body 3H3, and the scroll ring frame 3H1 is nested in the front side of the aluminum foil tremolo strip 3H2 and is located in On the same vertical plane, the aluminum foil tremolo bar 3H2 is mechanically connected with the rotary disc body 3H3 and the axis is collinear, and the aluminum foil tremolo bar 3H2 is lined by the spiral stack ring frame 3H1 to form a centrifugal convolution push effect of audio vibration. , to ensure that the fluctuation of the sound wave is large, the pitch output is sufficient, and the quality of the classroom after the foreign teacher's teaching is improved.

[0042] see Image 6 , the spiral ring frame 3H1 is composed of a three-ring
