[0024] Embodiment

[0025] Such as Figure 1 、 Figure 2 、 Figure 3 and Figure 4As shown in the figure, a hearing aid RIC module with an anti-rotation and anti-bending structure includes a sound generating unit 2. The sound generating unit 2 includes a sound generating unit outer housing 5 and a sound generating unit inner housing 4. A moving iron speaker assembly is connected inside the sound generating unit inner housing 4. The sound generating unit inner housing 4 is connected inside the sound generating unit outer housing 5. One end of the sound generating unit outer housing 5 is connected to a wire tube 1, and the other end of the sound generating unit outer housing 5 is connected to a RIC module sound guiding tube 3 that cooperates with the moving iron speaker assembly. The wire tube 1 includes a wire tube body 11 and a wire tube connector 12. One end of the wire tube body 11 is connected to the wire tube connector 12. A connecting groove ring 13 is formed on the wire tube connector 12, and a wire tube positioning protrusion 14 is connected inside the connecting groove ring 13. A positioning groove 15 that is engaged with the connecting groove ring 13 and the wire tube positioning protrusion 14 is formed on the sound generating unit outer housing 5, and the wire tube connector 12 is snap-fitted on the positioning groove 15.

[0026] In the present utility model, a positioning notch that matches the wire tube positioning protrusion 14 is formed at the bottom of the positioning groove 15. Among them, the positioning notch is of a square structure.

[0027] In the present utility model, the wire tube connector 12 is connected to the positioning groove 15 through industrial glue.

[0028] In the present utility model, a damping sleeve 16 for preventing the wire tube body 11 from being bent is connected to the end of the wire tube connector 12. At the same time, the wire tube body 11 passes through the damping sleeve and is inserted and connected to the wire tube connector 12.

[0029] The sound generating unit outer housing in the present utility model includes upper and lower sound generating unit outer housings. The wire tube connector 12 is snap-fitted through the upper and lower sound generating unit outer housings. At the same time, positioning grooves 15 are formed on both the upper and lower sound generating unit outer housings.
