Description

A pickup with a protective device Technical Field

[0001] This utility model relates to the field of microphone technology, specifically to a microphone with a protective device. Background Technology

[0002] A microphone is an electroacoustic device used to collect ambient sound and convert it into electrical signals for transmission to backend equipment. It mainly consists of a microphone and an audio amplification circuit. Its core working principle is to trigger a sensor through sound wave vibration, convert the sound signal into an electrical signal, and then output it after amplification, noise reduction, and other processing. According to the technology type, microphones are divided into digital and analog types, and can also be divided into active and passive types according to function. They have a wide range of applications, covering security monitoring, education, conference systems, aerospace, smart homes, remote medical consultations, and the music field.

[0003] In the prior art, protective devices are installed on microphones during use to prevent damage from external forces. However, the presence of these protective devices may affect the microphone's sound pickup performance, resulting in poor sound pickup and affecting its usability. Summary of the Invention

[0004] Therefore, the purpose of this utility model is to provide a microphone with a protective device to solve the technical problem that the sound pickup effect of a microphone with a protective device is affected by the protective device.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a microphone with a protective device, comprising a protective shell, a fixing ring fixedly connected to one side of the protective shell, a microphone body movably connected inside the protective shell, multiple sets of connecting rods rotatably connected to one side of the fixing ring, a sound-collecting cloth fixedly connected to one side of each set of connecting rods, a spherical fixing seat fixedly connected to the outer wall of each set of connecting rods, a driving rod rotatably connected to one side of the spherical fixing seat, one end of the driving rod rotatably connected to the microphone body, a rotating ring rotatably connected to the outer wall of the protective shell, and a base fixedly connected to one side of the microphone body by bolts, with the base located inside the protective shell.

[0006] By adopting the above technical solution, this utility model achieves displacement control through the threaded engagement of the rotating ring and the base, allowing the microphone body to be precisely adjusted to enter and exit the protective shell. When the device is unfolded, the linkage drive rod pushes multiple sets of connecting rods to form a spatial support structure. The unfolding is achieved in conjunction with the telescopic mechanism of the sliding tube and sliding rod, allowing the flexible sound-collecting cloth to naturally tighten and form a trumpet-shaped sound-collecting cavity. The sound wave reflection principle significantly enhances the sound signal acquisition efficiency. The ball shaft gives the connecting rods multi-directional rotational freedom, which can not only ensure the angle adaptive adjustment when the mechanism is unfolded, but also achieve tight fitting of components when stored. In the stored state, the flexible sound-collecting cloth automatically adheres to the surface of the equipment due to the elasticity of the material, forming a physical isolation layer that effectively resists dust corrosion. The overall structure achieves functional conversion through pure mechanical linkage, and can complete the switching of working states without electric drive. It has both convenient operation and environmental adaptability, solving the technical bottleneck of acoustic shielding in traditional protective devices. While ensuring the protection of the equipment, it actively enhances the sound pickup effect through the deformable acoustic structure, achieving synergistic optimization of equipment protection and acoustic performance.

[0007] Furthermore, one end of the connecting rod is fixedly connected to a first ball shaft, and a groove that mates with the first ball shaft is provided on one side of the fixing ring. The connecting rod is rotatably connected to the fixing ring via the first ball shaft. One end of the driving rod is fixedly connected to a second ball shaft, and a groove that mates with the second ball shaft is provided inside the spherical fixing seat. The second ball shaft is located inside the spherical fixing seat. The other end of the driving rod is fixedly connected to a third ball shaft, and a groove that mates with the third ball shaft is provided on one side of the microphone body. The driving rod is rotatably connected to the microphone body via the third ball shaft.

[0008] By adopting the above technical solution, the connecting rod can rotate on the fixed ring under the action of the first ball shaft, and the driving rod can move between the connecting rod and the microphone body under the action of the second ball shaft and the third ball shaft.

[0009] Furthermore, a fixed ball is fixedly connected to the other end of the connecting rod, a sliding tube is movably connected to one side of the fixed ball, and a sliding rod is movably connected to the other end of the fixed ball. A cavity is opened inside the sliding tube to cooperate with the sliding rod, and the sliding tube is slidably connected to the sliding rod through the cavity.

[0010] By adopting the above technical solution, a sliding tube and a sliding rod are installed at one end of the connecting rod. After the connecting rod is fully extended, the sliding tube and the sliding rod will be stretched to their longest state. After the connecting rod is rotated inward by the microphone body, the sliding rod will slide inside the sliding tube.

[0011] Furthermore, the rotating ring has an internal thread inside, and the outer wall of the base has an external thread. The rotating ring is rotatably connected to the base through thread engagement.

[0012] By adopting the above technical solution, the user can manually rotate the rotating ring. Since the inner wall of the rotating ring has internal threads and the outer wall of the base has external threads, the threads mesh with each other. After the rotating ring rotates, the base will move inside the protective shell. The base is connected to the microphone body by bolts. Therefore, after the base moves, it will move the microphone body inside the protective shell.

[0013] In summary, this utility model has the following beneficial effects: The utility model achieves displacement control through the threaded engagement of the rotating ring and the base, allowing the microphone body to precisely adjust its movement in and out of the protective shell. When the device is unfolded, the linkage drive rod pushes multiple sets of connecting rods to form a spatial support structure. This, combined with the telescopic mechanism of the sliding tube and sliding rod, enables the unfolding of the device, allowing the flexible sound-collecting cloth to naturally tighten and form a trumpet-shaped sound-collecting cavity. Utilizing the principle of sound wave reflection, this significantly enhances the efficiency of sound signal acquisition. The ball shaft provides the connecting rods with multi-directional rotational freedom, ensuring both adaptive angle adjustment during unfolding and tight fit of components during storage. In the stored state, the flexible sound-collecting cloth automatically adheres to the device surface due to its material elasticity, forming a physical isolation layer that effectively resists dust corrosion. The overall structure achieves functional conversion through pure mechanical linkage, requiring no electric drive to switch working states. It combines ease of operation with environmental adaptability, solving the technical bottleneck of acoustic shielding in traditional protective devices. While ensuring equipment protection, it actively enhances the sound pickup effect through a deformable acoustic structure, achieving synergistic optimization of equipment protection and acoustic performance.

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0023] The embodiments of this utility model will be described below based on its overall structure.

[0024] A microphone with a protective device, as shown in Figures 1-7, includes a protective shell 1, a fixed ring 2 fixedly connected to one side of the protective shell 1, a rotating ring 14 rotatably connected to the outer wall of the protective shell 1, and a base 15 fixedly connected to one side of the microphone body 3 by bolts, with the base 15 located inside the protective shell 1. The rotating ring 14 has an internal thread, and the outer wall of the base 15 has an external thread. The rotating ring 14 is rotatably connected to the base 15 through thread engagement.

[0025] The user can manually rotate the rotating ring 14. Since the inner wall of the rotating ring 14 has internal threads and the outer wall of the base 15 has external threads, the threads mesh with each other. After the rotating ring 14 is rotated, the base 15 will move inside the protective shell 1. The base 15 is connected to the microphone body 3 by bolts. Therefore, after the base 15 moves, it will move the microphone body 3 inside the protective shell 1.

[0026] Furthermore, the microphone body 3 is movably connected inside the protective shell 1, and multiple sets of connecting rods 5 are rotatably connected to one side of the fixing ring 2. Each set of connecting rods 5 is fixedly connected to one side of the sound-collecting cloth 4, and a spherical fixing seat 13 is fixedly connected to the outer wall of each set of connecting rods 5. A drive rod 6 is rotatably connected to one side of the spherical fixing seat 13, and one end of the drive rod 6 is rotatably connected to the microphone body 3.

[0027] When the microphone body 3 moves out of the protective shell 1, multiple sets of drive rods 6 will push up multiple sets of connecting rods 5. The multiple sets of connecting rods 5 are connected to the sound-collecting cloth 4. After the microphone body 3 is completely out of the protective shell 1, the connecting rods 5 will be fully opened. Since the sound-collecting cloth 4 is made of flexible material, it will be tightened under the action of the multiple sets of connecting rods 5, so that the overall sound-collecting cloth 4 is in the shape of a trumpet, thereby making the sound-collecting effect of the microphone body 3 better.

[0028] In the example, one end of the connecting rod 5 is fixedly connected to the first ball shaft 7, and a groove that mates with the first ball shaft 7 is provided on one side of the fixing ring 2. The connecting rod 5 is rotatably connected to the fixing ring 2 through the first ball shaft 7. One end of the driving rod 6 is fixedly connected to the second ball shaft 8, and a groove that mates with the second ball shaft 8 is provided inside the spherical fixing seat 13. The second ball shaft 8 is located inside the spherical fixing seat 13. The other end of the driving rod 6 is fixedly connected to the third ball shaft 9, and a groove that mates with the third ball shaft 9 is provided on one side of the microphone body 3. The driving rod 6 is rotatably connected to the microphone body 3 through the third ball shaft 9.

[0029] Under the action of the first ball shaft 7, the connecting rod 5 can rotate on the fixed ring 2. Under the action of the second ball shaft 8 and the third ball shaft 9, the driving rod 6 can move between the connecting rod 5 and the microphone body 3.

[0030] In the example, a fixed ball 10 is fixedly connected to the other end of the connecting rod 5, a sliding tube 11 is movably connected to one side of the fixed ball 10, and a sliding rod 12 is movably connected to the other end of the fixed ball 10. A cavity is opened inside the sliding tube 11 to cooperate with the sliding rod 12, and the sliding tube 11 is slidably connected to the sliding rod 12 through the cavity.

[0031] One end of the connecting rod 5 is equipped with a sliding tube 11 and a sliding rod 12. After the connecting rod 5 is fully extended, the sliding tube 11 and the sliding rod 12 will be stretched to their longest state. After the connecting rod 5 is rotated inward by the microphone body 1, the sliding rod 12 will slide inside the sliding tube 11.

[0032] The working principle of this utility model is as follows: When in use, the user can first manually rotate the rotating ring 14. Since the inner wall of the rotating ring 14 is provided with internal threads and the outer wall of the base 15 is provided with external threads, the threads mesh with each other. After the rotating ring 14 is rotated, the base 15 will move inside the protective shell 1.

[0033] The base 15 is connected to the microphone body 3 by bolts, so when the base 15 moves, it will move the microphone body 3 inside the protective shell 1.

[0034] When the microphone body 3 moves out of the protective shell 1, multiple sets of drive rods 6 will push up multiple sets of connecting rods 5. The multiple sets of connecting rods 5 are connected by the sound-collecting cloth 4. After the microphone body 3 is completely out of the protective shell 1, the connecting rods 5 will be fully opened. A sliding tube 11 and a sliding rod 12 are installed at one end of the connecting rod 5. At this time, the sliding tube 11 and the sliding rod 12 will be stretched to their longest state.

[0035] Meanwhile, under the action of the first ball shaft 7, the connecting rod 5 can rotate on the fixed ring 2, and under the action of the second ball shaft 8 and the third ball shaft 9, the driving rod 6 can move between the connecting rod 5 and the microphone body 3;

[0036] Since the microphone cloth 4 is made of flexible material, it will be tightened under the action of multiple connecting rods 5, so that the overall microphone cloth 4 is in the shape of a trumpet, thereby making the microphone body 3 have a better sound pickup effect.

[0037] After use, the user can reverse the rotating ring 14 to move the base 15 and the microphone body 3 into the protective shell 1. This will cause multiple sets of drive rods 6 to rotate together with multiple sets of connecting rods 5 into the protective shell 1, and the sliding rod 12 will slide inside the sliding tube 11 until the sliding rod 12 is completely inside the sliding tube 11.

[0038] At this time, the microphone body 3 will be completely inserted into the protective shell 1, and the microphone cloth 4 will be attached to the outer wall of the microphone body 3 together with the connecting rod 5 under the action of its own flexible material, thereby protecting the microphone body 3.

[0039] The above structure solves the technical problem that the sound pickup performance of a microphone with a protective device installed is affected by the protective device.
