Description

Technical Field

[0001] The utility model relates to the technical field of microphones, in particular to an emergency microphone with a multi-mode disassembly structure. Background Art

[0002] Microphone, scientific name is microphone, also known as microphone, micro-phone. Microphone is an energy conversion device that converts sound signals into electrical signals. There are dynamic, condenser, electret and the recently emerging silicon micro-microphone, in addition to liquid microphones and laser microphones. Most microphones are electret condenser microphones, which work on the principle of using a polymer material vibration membrane with permanent charge isolation.

[0003] Most of the current microphone products are in an integral fixed form. The overall structure of the microphone does not have the function of self-disassembly. The environment in which the microphone is used is complex, so it does not have the performance of secondary structural disassembly and change in different use environments. It is difficult to adapt to the emergency use needs of sudden interviews or environmental changes. For example, when used in a crowded environment, due to the short length of the microphone, the staff is prone to detach from the original fixed position or clamping position due to external weather or other interference factors when using the microphone for interviews, causing the collected sound to be unstable and unsmooth. It is also easy to collide with the surrounding people or other objects, and there is a risk of the microphone accidentally falling to the ground. Secondly, when the microphone is used in the outside world in bad weather, the rain in the external environment will wet the microphone, making it impossible to continue to use. If the staff does not carry a spare microphone, they will not be able to continue to work effectively, so that the relevant collection work can only be forced to stop. The current microphone lacks a structural form that can be deformed on demand according to actual use and environmental conditions, and lacks the performance of emergency changes.

After the two fixed shafts mounted on the outer wall of the first microphone body 8 are placed in the arc grooves at the top of the two vertical plates 6, the two rotating plates 11 are rotated downward to abut against the top of the vertical plates 6.

[0028] As a technical optimization solution in the utility model, rubber pads 12 are installed inside the arc grooves, and the ends of the two rotating plates 11 away from the rotating parts are threadedly connected to the top of the vertical plate 6 through bolts. After the two rotating plates 11 are rotated downward to abut against the top of the vertical plate 6, the rubber pads 12 arranged inside the arc grooves of the two rotating plates 11 can be tightly abutted against the outer wall of the fixed shaft. After the rotating plates 11 and the vertical plates 6 are connected and fixed by bolts, the fixed shaft is clamped and fixed, and the installation of the first microphone body 8 is completed; and according to actual use needs, after the first microphone body 8 is placed on the top of the two vertical plates 6, the angle of the first microphone body 8 itself can be adjusted, so that the angle of the first microphone body 8 can be adjusted when in use.

[0029] As a technical optimization solution in the utility model, the protection mechanism includes a protective cover 7, which is installed between the two vertical plates 6. The top of the protective cover 7 is provided with a closing portion, and a drawstring 10 is inserted into the closing portion. The protective cover 7 is made of cotton cloth material. After the first microphone body 8 is used, the first microphone body 8 is rotated downward so that the mesh cover at the top is rotated to the inside of the protective cover 7, and the two ends of the drawstring 10 are pulled to drive the closing portion to closely abut against the outer wall of the first microphone body 8, so that the protective cover 7 can protect the mesh cover after being rotated downward.

A telescopic groove is provided at one end of the second threaded portion 15 away from the sleeve 4, and when the fastening sleeve 16 is screwed, the inner wall of the end of the second threaded portion 15 away from the sleeve 4 can be driven to closely abut against the outer wall of the connecting pipe 3, so as to facilitate the position of the sleeve 4 outside the connecting pipe 3 to be limited and fixed; the first threaded portion 14 provided at the top of the sleeve 4 is threadedly connected with the threaded hole 13, so that the sleeve 4 and the base 5 are detachably arranged.

[0032] As a technical optimization solution in the utility model, a storage groove 21 is provided inside the connecting tube 3, and the second microphone body 18 is placed inside the storage groove 21. A rubber ring 19 is provided at the top of the connecting tube 3, and two fasteners 2 for limiting the length after adjustment are installed on the outside of the bracket 1. When the first microphone body 8 is damaged and cannot be used, the sleeve 4 can be removed from the bottom of the base 5, and the sleeve 4 can be slid downward on the surface of the connecting tube 3 to expose the second microphone body 18 located inside the connecting tube 3. After the second microphone body 18 is taken out from the storage groove 21, it can continue to be used, avoiding the problem that the first microphone body 8 is damaged and cannot continue to work; the rubber ring 19 provided at the top of the connecting tube 3 can ensure that after the second microphone body 18 is placed inside the storage groove 21, the friction between the second microphone body 18 and the inner wall of the storage groove 21 is increased, avoiding the second microphone body 18 shaking inside the storage groove 21 and being damaged.

[0033] In the utility model, Figure 1As shown, when the bracket 1, the connecting tube 3 and the sleeve 4 are located at the bottom of the base 5 and connected for use, the staff can hold the bracket 1 to increase the height of the first microphone body 8, and use the first microphone body 8 on the top of the base 5 to interview other people, etc., which can avoid interference with the first microphone body 8 caused by surrounding noise or electromagnetic waves due to the low height of the first microphone body 8, thereby helping to improve the quality of sound collection.

[0034] When it is necessary to use them separately, the first microphone body 8 and the bracket 1 can be separated by disassembling the sleeve 4 and the base 5. The sleeve 4 and the base 5 are separated by twisting the first threaded portion 14, and the bracket 1 is retracted to facilitate the staff to carry it.

[0035] When only the first microphone body 8 needs to be used alone, the threads between the two rotating plates 11 and the vertical plate 6 are removed, and the two rotating plates 11 are rotated upward so that the two ends of the fixed axis lose the clamping and fixing effect brought by the rubber pads 12, making it convenient to remove the first microphone body 8 from the top of the base 5 for separate use.

[0036] At the same time, when it is necessary to place the first microphone body 8 on a desktop for use, the sleeve 4 can be directly removed from the bottom of the base 5, so that the base 5 can be used as a placement table, and the base 5 can be directly placed on the top of the desktop, and the angle of the first microphone body 8 can be adjusted for use without the need for additional corresponding support frame to support the first microphone body 8.

[0037] When the staff uses the first microphone body 8 in the external environment, if the first microphone body 8 collides with other objects or is wet by external rain, causing the first microphone body 8 to be unusable, the sleeve 4 can be removed from the bottom of the base 5, and the fastening sleeve 16 can be screwed to make the bottom end of the sleeve 4 lose connection with the outer wall of the connecting tube 3, and the sleeve 4 can slide downward on the surface of the connecting tube 3 to expose the second microphone body 18 inside the connecting tube 3. The staff can quickly take out the second microphone body 18 from the storage slot 21 and continue to use it, avoiding damage to the first microphone body 8 and affecting the normal work progress, ensuring continuous and effective use.

[0038] After the first microphone body 8 is used, the first microphone body 8 is rotated downward so that the mesh cover at the top thereof is rotated to the inside of the protective cover 7, and the two ends of the pull rope 10 are pulled to drive the closing part to tightly abut against the outer wall of the first microphone body 8, so that the protective cover 7 can protect the mesh cover after being rotated downward, and then one of the connecting parts 9 is rotated and attached to the surface of the mesh cover, and then the Velcro hook surface of the inner wall of the other connecting part 9 is adhered to the Velcro fur surface of the outer wall of one of the connecting parts 9, so that the mesh cover can be completely wrapped, thereby avoiding the problem that when the first microphone body 8 is not in use, there are debris attached to the surface of the mesh cover, which affects the subsequent use.
