Description

Technical Field

[0001] This utility model relates to the field of microphone technology, and in particular to a surround sound noise-canceling microphone. Background Technology

[0002] A microphone, scientifically known as a transducer, is a device that converts sound signals into electrical signals. Microphones are classified into dynamic, condenser, electret, and the recently emerging silicon micro-microphones. In addition, there are liquid microphones and laser microphones. In professional recording studios, stands are needed to support surround sound noise-canceling microphones for audio recording.

[0003] Currently, Chinese patent CN217563755U discloses a microphone stand and microphone device for supporting and limiting a microphone. The device includes a support, a fixing member, and a vibration damping member. The support is placed on an external support. The fixing member is connected to the support and has a receiving hole for supporting and fixing the microphone. The microphone is housed within the receiving hole, and there is a gap between the receiving hole and the microphone. The vibration damping member fills the gap and extends along the outer periphery of the microphone. The inner and outer peripheral walls of the vibration damping member are respectively connected to the microphone and the fixing member. During microphone use, when external vibration occurs, the vibration is transmitted to the fixing member of the stand, and then transmitted to the microphone through the vibration damping member. The vibration is weakened by the vibration damping member, so when it is transmitted to the microphone, the microphone vibrates slightly or not at all. This vibration will not affect the microphone's reception of audio signals and will produce high-definition, noise-free voice information. This microphone stand enhances the microphone's vibration resistance and improves voice quality.

[0004] Most current surround sound microphones are inconvenient to disinfect after use. Although there are spray shields on the front of the surround sound microphone to block saliva, some saliva still floats and adheres to the surface of the microphone. Saliva can easily breed bacteria on the surface of the surround sound microphone, affecting the hygiene of the microphone. Utility Model Content

[0020] In this embodiment: by limiting the surround sound noise-canceling microphone body 4 inside the fixing ring 3, after the surround sound noise-canceling microphone body 4 is used, the bracket 201 is moved upward until the ultraviolet lamp 202 is close to the surround sound noise-canceling microphone body 4, and then the ultraviolet lamp 202 is controlled to work. The ultraviolet lamp 202 can disinfect the surface of the surround sound noise-canceling microphone body 4. This avoids the inconvenience of disinfecting most existing surround sound microphones after use. Although the surround sound microphone is equipped with a spray shield to block saliva, some saliva will still adhere to the surface of the surround sound microphone. Saliva can easily breed bacteria on the surface of the surround sound microphone, affecting the hygiene of the surround sound microphone.

[0021] As a technical optimization of this utility model, the support rod 5 has a sliding groove 8 inside, and the rear side of the bracket 201 is fixedly connected to a slider 13.

[0022] In this embodiment, the bracket 201 can be moved easily by sliding the slider 13 inside the slide groove 8, thus achieving the effect of facilitating the movement of the bracket 201.

[0023] As a technical optimization of this utility model, a limiting ring 9 is provided on the rear side of the slider 13, and a limiting post 14 is fixedly connected to the rear side of the slider 13. The inner wall of the limiting ring 9 is threadedly connected to the surface of the limiting post 14.

[0024] In this embodiment, the inner wall of the limiting ring 9 is threadedly connected to the surface of the limiting post 14, so that the limiting ring 9 can move when it rotates, thus achieving the effect of facilitating the movement of the limiting ring 9.

[0025] As a technical optimization of this utility model, a rubber pad 12 is fixedly connected to the front side of the limiting ring 9. There are several rubber pads 12, and the front side of the rubber pad 12 is tightly connected to the rear side of the support rod 5.

[0026] In this embodiment: by moving the limiting ring 9 to make close contact between the front side of the anti-slip pad 15 and the rear side of the support rod 5, the contact between the bracket 201 and the support rod 5 can be made tighter, making the bracket 201 more stable, thus achieving the effect of making the limiting ring 9 and the bracket 201 make closer contact.

[0027] As a technical optimization of this utility model, a handle 10 is fixedly connected to the top of the bracket 201, and screw posts 11 are fixedly connected to both sides of the rear side of the limiting ring 9.

[0028] In this embodiment: by holding the handle 10 and moving the handle 10 upward, the bracket 201 can be moved, which achieves the effect of conveniently pulling the bracket 201 and rotating the limiting ring 9.

[0029] As a technical optimization of this utility model, a fixing ring 3 is fixedly connected to the front side of the support rod 5, and a rubber ring 6 is fixedly connected to the inner wall of the fixing ring 3. The surface of the surround sound noise reduction microphone body 4 is in contact with the inner wall of the rubber ring 6.

[0030] In this embodiment: by moving the surround sound noise-canceling microphone body 4 until the surface of the surround sound noise-canceling microphone body 4 contacts the inner wall of the rubber ring 6, the rubber ring 6 can prevent vibration between the surround sound noise-canceling microphone body 4 and the fixed ring 3, thus avoiding affecting the recording effect of the surround sound noise-canceling microphone body 4 and achieving the effect of preventing vibration between the surround sound noise-canceling microphone body 4 and the fixed ring 3.

[0031] As a technical optimization of this utility model, a rubber baffle 7 is fixedly sleeved on the surface of the surround sound noise reduction microphone body 4, and the bottom of the rubber baffle 7 contacts the top of the fixing ring 3.

[0032] In this embodiment: by contacting the bottom of the rubber baffle 7 with the top of the fixing ring 3, the rubber baffle 7 can limit the surround sound noise-canceling microphone body 4, thus achieving the effect of limiting the surround sound noise-canceling microphone body 4.

[0033] As a technical optimization of this utility model, the bottom of the base plate 1 is fixedly connected with an anti-slip pad 15, and the number of anti-slip pads 15 is several and they are evenly distributed on the bottom of the base plate 1.

[0034] In this embodiment: by moving the base plate 1 to a stable tabletop, the anti-slip pad 15 can provide stable support for the base plate 1, thus achieving the effect of stable support for the base plate 1.

[0035] Working principle: First, move the base plate 1 to a stable tabletop. The anti-slip pad 15 will then provide stable support. Next, move the surround sound noise-canceling microphone body 4 until its surface contacts the inner wall of the rubber ring 6. The rubber ring 6 will prevent vibration between the surround sound noise-canceling microphone body 4 and the fixing ring 3, thus avoiding impact on the recording effect. The bottom of the rubber baffle 7 contacts the top of the fixing ring 3, limiting the position of the surround sound noise-canceling microphone body 4. At this point, the support rod 5 and the fixing ring 3 will support the surround sound noise-canceling microphone body 4. After using the surround sound noise-canceling microphone body 4, hold the handle 10 and move it upwards to move the slider 13 upwards inside the slide groove 8. This will move the bracket 201, the arc plate 203, and the ultraviolet lamp 202 closer to the surround sound noise-canceling microphone body 4. Then, rotate the limiting ring 9. The limiting ring 9, through its contact with the limiting... The threaded connection between the positioning posts 14 allows the limiting ring 9 to move when it rotates, bringing it into close contact with the front of the rubber pad 12 and the rear of the support rod 5. This increases the friction between the bracket 201 and the support rod 5, thus limiting the bracket 201, the arc plate 203, and the ultraviolet lamp 202. The ultraviolet lamp 202 is then activated to disinfect the surface of the surround sound noise-canceling microphone body 4. This avoids the inconvenience of disinfecting most existing surround sound microphones after use. Although a pop filter is installed in front of the surround sound microphone to block saliva, some saliva still adheres to its surface, easily breeding bacteria and affecting hygiene. The close contact between the surface of the rubber pad 12 and the rear of the support rod 5 ensures a tighter connection between the support rod 5 and the bracket 201, preventing vibration of the bracket 201 from affecting the recording effect.

[0036] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
