Embodiment 1
[0044] Embodiment 1, the present embodiment provides a kind of singing breath exercise device, refer to the attached figure 1 As shown, including the practice tube 1, we communicate with the blowing tube 2 at the bottom of the practice tube 1, so that the singer blows air into the practice tube 1 through the blowing tube 2 when practicing. It is characterized in that, referring to the attached Figure 4 Shown, we are installed with fan blade 4 coaxially rotating in practice tube 1, and we are provided with two magnets 3 at intervals on the upper end face of practice tube 1 (we make the N level of two magnets 3 and The S-class is set opposite to each other, that is, a closed magnetic field is formed), refer to the attached Figure 4 As shown, we are provided with a conductive frame 5 that rotates coaxially with the fan blade 4 between the two magnets 3 and the upper end of the conductive frame 5 is connected with a current detection device. When the singer blows through the blo...
Embodiment 2
[0048] Embodiment 2, on the basis of embodiment 1, with reference to appended Figure 5 As shown, one end of the connecting rod 7 near the rotating circle 9 is integrally provided with a transitional rod 15 having a width less than the connecting rod 7 and the transitional rod 15 is equipped with an arc-shaped plate 16 facing the side of the rotating circle (the width of the arc-shaped plate 16 is the same as that of the connecting rod 7), refer to attached Figure 13 As shown, we set the socket 17 corresponding to the arc plate 16 on the inner surface of the rotating ring 9 (we make the width of the socket 17 the same as the width of the connecting rod 7 when setting the socket 17), refer to the attached Figure 14 As shown, the positioning device includes: an arc-shaped positioning block 18 arranged on both sides of the jack 17 and slidably installed in the rotating circle 9 along the direction perpendicular to the jack 17. When we set the two arc-shaped positioning blocks 1...
Embodiment 3
[0049] Embodiment 3, on the basis of embodiment 2, with reference to appended Figure 19 As shown, the unlocking gear 11 drives a one-way half-gear 20 coaxially arranged therewith, and the one-way half-gear 20 is rotatably mounted on the shaft of the unlocking gear 11 (we rotate and install a pawl on the shaft of the unlocking gear 11 68 and on the inner surface of the one-way half gear 20, a number of ratchets 67 that match the pawl 68 are arranged around at intervals. We fix an elastic block 69 that interferes with the pawl 68 on the unlocking gear 11 shaft, for realize the reset of the pawl 68), refer to the attached Figure 13 The shown energy storage exit device includes a coil spring 21 that is connected to the unlocking gear 11 and the other end of the coil spring 21 is connected to the inner wall of the rotating ring 9. When blowing air in the tube 1, the rotating circle 9 is driven by the fan blade 4 along the Figure 13 Rotate in the clockwise direction shown in , ...
