[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-Figure 4 , the utility model provides a technical solution:

[0023] Embodiment 1:

[0024] See also Figure 1-Figure 4 A retractable directional microphone comprises a microphone body 1 and a microphone 3. A retractable component 2 is arranged inside the microphone body 1, and the retractable component 2 is used to adjust the distance between the microphone 3 and the microphone body 1. The retractable component 2 comprises a connecting rod 201 rotatably connected to the microphone body 1, and a gear 202 is fixedly installed at one end of the connecting rod 201 extending to the inside of the microphone body 1, and a rack 203 meshing with the gear 202 is arranged inside the microphone body 1, and a connecting plate 204 is fixedly installed on the top of the rack 203, and two supporting rods 205 are fixedly installed on the outer wall of the connecting plate 204, and a circular push plate 206 is fixedly installed between the two supporting rods 205, and one end of the support rod 205 away from the connecting plate 204 is fixedly connected to the outer wall of the circular push plate 206, and the circular push plate 206 corresponds to one end of the microphone 3.

[0025] Since the environmental noise is high when recording human voice, the length of the microphone 3 can be adjusted so that the user can easily cope with different sound collection distance requirements to ensure that the sound can be captured clearly. The connecting rod 201 is rotated to drive the gear 202 to rotate. When the gear 202 rotates, the rack 203 moves. When the rack 203 moves toward the direction of the microphone 3, the rack 203 drives the connecting plate 204 and the supporting rod 205 to move together.

[0026] The support rod 205 pushes the circular push plate 206 to move, and the circular push plate 206 can push the microphone 3 to move horizontally, so that the microphone 3 is away from the microphone body 1. When the gear 202 is rotated in the reverse direction, the circular push plate 206 and the microphone 3 can be retracted.

[0027] See also Figure 2 A fixing block 6 is fixedly installed on the inner wall of the microphone body 1, a guide rod 5 is fixedly installed between the outer wall of the fixing block 6 and the inner wall of the microphone body 1, the rack 203 is slidably connected to the outer wall of the guide rod 5, the top of the fixing block 6 is parallel to the top of the rack 203, and a distance is left between the support rod 205 and the top of the fixing block 6.

[0028] The guide rod 5 provides guidance and support for the rack 203, so that the rack 203 can slide along the outer wall of the guide rod 5 without contacting the microphone body 1. The guide rod 5 makes the rack 203 more stable and has support during movement. The stability of the rack 203 also enables the connecting plate 204 and the support rod 205 to better support the circular push plate 206 and the microphone 3. A distance is left between the fixed block 6 and the support rod 205, so that the support rod 205 will not rub against the fixed block 6 when moving.

[0029] See also Figure 2-Figure 3 A knob 4 is fixedly mounted on one end of the connecting rod 201 extending to the outside of the microphone body 1 , and a plurality of teeth are integrally formed on the outer wall of the knob 4 , leaving a gap between the knob 4 and the outer wall of the microphone body 1 .

[0030] The knob 4 provides assistance to the connecting rod 201, making the connecting rod 201 easier to operate. The connecting rod 201 can be driven to rotate by pinching the knob 4 and turning it. The multiple teeth on the knob 4 increase the friction of the knob 4, making it less likely for the hand to slip when turning the knob 4.

[0031] See also Figure 2 An L-shaped mounting rod 7 is fixedly mounted on the top of the rack 203 , and one end of the L-shaped mounting rod 7 away from the rack 203 is fixedly connected to the outer wall of the connecting plate 204 .

[0032] Since the contact area between the connecting plate 204 and the rack 203 is small, the connecting plate 204 may be unstable. The L-shaped mounting rod 7 increases the connection area between the connecting plate 204 and the rack 203, so that the connecting plate 204 can be more firmly connected to the rack 203 to prevent the connecting plate 204 from loosening.

[0033] Embodiment 2:

[0034] See also Figure 2 and Figure 4 The inner wall of the microphone body 1 is rotatably connected to the screw rod 8, the connecting plate 204 is threadedly connected to the outer wall of the screw rod 8, the circular push plate 206 does not contact the screw rod 8, the outer wall of the screw rod 8 is threadedly connected to the threaded slider 9, and the outer wall of the threaded slider 9 is fixedly installed with two slides 11, and a circular fixing plate 12 is fixedly connected between the two slides 11, and one end of the microphone 3 is fixedly connected to the outer wall of the circular fixing plate 12.

[0035] When the connecting plate 204 moves horizontally toward the direction of the microphone 3, the connecting plate 204 drives the screw rod 8 to rotate. This is because a thread is provided at the connection between the connecting plate 204 and the screw rod 8. Therefore, when the connecting plate 204 moves together with the thread, the thread pushes the thread on the outer wall of the screw rod 8, thereby causing the screw rod 8 to rotate.

[0036] When the screw rod 8 rotates, the threaded slider 9 will slide along the outer wall of the screw rod 8. The threaded slider 9 will move along the outer wall of the screw rod 8 toward the direction of the microphone 3, and at the same time, the slide plate 11 and the circular fixed plate 12 will move together. When the slide plate 11 moves, it will slide along the inner wall of the circular push plate 206.

[0037] The circular fixing plate 12 will push the microphone 3 to move when it moves, thereby achieving the adjustment of the position of the microphone 3 together with the telescopic component 2. The movement of the circular fixing plate 12 increases the overall movement distance of the telescopic component 2 for the microphone 3, so that the microphone 3 can be moved to a position farther away from the microphone body 1, thereby increasing the movable range of the microphone 3.

[0038] See also Figure 2 and Figure 4 The outer walls of the circular push plate 206 and the circular fixed plate 12 are fixedly connected with a protective cover 10, the protective cover 10 is slidably connected to the inner wall of the microphone body 1, the slide plate 11 is plugged into the circular push plate 206, and the circular fixed plate 12 is located on the side of the slide plate 11 away from the threaded slider 9.

[0039] Since the movable circular push plate 206 and the circular fixed plate 12 need to enter and exit the interior of the microphone body 1 many times, the outer walls of the circular push plate 206 and the circular fixed plate 12 will rub against the inner wall of the microphone body 1, which may cause wear. The protective cover 10 is blocked between the inner wall of the microphone body 1 and the outer walls of the circular push plate 206 and the circular fixed plate 12, thereby avoiding the possibility of wear between the circular push plate 206 and the circular fixed plate 12 and the microphone body 1. The connection between the slide plate 11 and the circular push plate 206 allows the slide plate 11 to slide along the inner wall of the circular push plate 206 when moving, so as to prevent the circular push plate 206 from hindering the movement of the slide plate 11.

[0040] Working principle:

[0041] Since the environmental noise is high when recording human voice, the length of the microphone 3 can be adjusted so that the user can easily cope with different sound collection distance requirements to ensure that the sound can be captured clearly. The connecting rod 201 is rotated to drive the gear 202 to rotate. When the gear 202 rotates, the rack 203 moves. When the rack 203 moves toward the direction of the microphone 3, the rack 203 drives the connecting plate 204 and the supporting rod 205 to move together.

[0042] The support rod 205 pushes the circular push plate 206 to move, and the circular push plate 206 can push the microphone 3 to move horizontally, so that the microphone 3 is away from the microphone body 1. When the gear 202 is rotated in the reverse direction, the circular push plate 206 and the microphone 3 can be retracted.

[0043] When the connecting plate 204 moves horizontally toward the direction of the microphone 3, the connecting plate 204 drives the screw rod 8 to rotate. This is because a thread is provided at the connection between the connecting plate 204 and the screw rod 8. Therefore, when the connecting plate 204 moves together with the thread, the thread pushes the thread on the outer wall of the screw rod 8, thereby causing the screw rod 8 to rotate.

[0044] When the screw rod 8 rotates, the threaded slider 9 will slide along the outer wall of the screw rod 8. The threaded slider 9 will move along the outer wall of the screw rod 8 toward the direction of the microphone 3, and at the same time, the slide plate 11 and the circular fixed plate 12 will move together. When the slide plate 11 moves, it will slide along the inner wall of the circular push plate 206.

[0045] The circular fixing plate 12 will push the microphone 3 to move when it moves, thereby achieving the adjustment of the position of the microphone 3 together with the telescopic component 2. The movement of the circular fixing plate 12 increases the overall movement distance of the telescopic component 2 for the microphone 3, so that the microphone 3 can be moved to a position farther away from the microphone body 1, thereby increasing the movable range of the microphone 3.
