Description

Technical Field

[0001] The utility model relates to the technical field of microphones, in particular to a handheld microphone. Background Art

[0002] Science and technology information publicity equipment is a series of tools and equipment used to spread and promote science and technology information and knowledge. These equipment play an important role in science and technology publicity, education, display and popularization of science and technology knowledge. At present, common publicity equipment includes multimedia projectors, display boards, and audio and microphone equipment used by staff to explain and publicize science and technology information. With the help of microphones, staff can more easily publicize science and technology information related content. China has authorized a utility model patent (publication number: CN220191014U) to propose a handheld microphone that is resistant to falling and impact. A rubber hanging ring is connected to the bottom of the handheld microphone through an elastic rope. When using the microphone, the rubber hanging ring can be put on the user's finger, so that when the microphone accidentally falls, it can prevent the microphone from falling to the ground and causing damage;

[0003] However, when the above device is used, the elastic rope needs to be completely removed from the accommodating chamber;

[0004] When the elastic cord exposed to the outside is relatively long, the staff can put the hanging ring on the finger, but at this time, the elastic cord is loose and exposed to the outside, which makes the appearance of the microphone look not neat. When it is entangled with other equipment or objects during use, it is easy to cause the elastic cord to be worn or even broken, which brings inconvenience to the user. At the same time, when not in use, the staff also needs to organize the elastic cord and place it in the accommodating chamber, which increases the workload of the staff;

[0005] When the exposed elastic cord is relatively short, the staff can put the hanging ring on the finger and hold the microphone, and the appearance of the microphone will appear relatively neat, but the elastic cord is in a stretched state. Long-term stretching will cause material fatigue of the elastic cord and accelerate its aging process.

[0006] Aiming at the shortcomings of microphones used for the promotion of scientific and technological information in the above situation, a handheld microphone is proposed. Utility Model Content

[0007] The utility model aims to solve the disadvantages of the prior art that the elastic cord is easy to get tangled, which may cause the elastic cord to be worn or even broken, thus bringing inconvenience to the user, and thus provides a handheld microphone.

[0008] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0009] A handheld microphone comprises a microphone body. A storage groove is provided on the microphone body. A roller body is arranged in the storage groove. The cross-sectional projection of the roller body is in an "H" shape. The two ends of the roller body are set as convex parts, and the middle end of the roller body is set as a concave part.

[0010] A pair of recesses are each provided with a torsion spring, which is respectively connected to the surface of the storage groove and the protrusion. The recess is provided with a connecting rope, and the connecting rope is fixedly connected with a hanging ring at one end away from the recess.

[0011] A pair of storage boxes are arranged outside the microphone body, the storage boxes are provided with square grooves, the square grooves are provided with battery storage grooves, spare batteries are placed in the battery storage grooves, and the storage boxes are provided with a first cover plate for covering the square grooves.

[0012] Preferably, a pair of circular grooves are provided inside the receiving groove, and the two ends of the roller body are rotatably matched with the grooves respectively.

[0013] Preferably, the microphone body is further provided with a second cover plate for covering the storage slot, and the second cover plate is provided with a through slot for the connecting rope to pass through.

[0014] Preferably, a pair of slots is provided on the square groove, and a pair of inserting blocks is provided on the first cover plate, and the pair of inserting blocks cooperates with the pair of slots.

[0015] Preferably, the square groove is provided with an arc groove on a side away from the slot, a clamping groove is provided in the arc groove, and the first cover plate is provided with a clamping block at one end away from the pair of inserting blocks, and the clamping block cooperates with the clamping groove.

[0016] Preferably, a silicone pad is provided at the bottom of the first cover plate, and the bottom of the silicone pad contacts the top of the spare battery placed in the battery storage slot.

[0017] The utility model has the following beneficial effects:

[0018] 1. The utility model uses the structural design of the storage groove, roller body, torsion spring, connecting rope and hanging ring so that the connecting rope can be effectively stored on the roller body. When in use, the user only needs to pull out the connecting rope of corresponding length as needed, and then put the hanging ring on the finger to easily fix the microphone body to prevent it from falling. At the same time, there will be no situation where the exposed loose connecting rope is entangled with other equipment, which avoids unnecessary interference to the user when using the microphone body. In addition, when the user no longer needs to use the microphone body, he only needs to loosen the hanging ring, and the connecting rope will be automatically recovered to the roller body under the action of the torsion spring, without the need for manual arrangement by the user, thus saving the user's time.

[0019] 2. The utility model enables the microphone body to have the ability to store things through the structural design of the storage box, square slot, battery storage slot, first cover plate and spare battery. When the battery used in the microphone body is low on power, the user can quickly replace the battery to ensure the normal progress of the promotional activities. This not only avoids the interruption of promotion due to power problems, but also improves the efficiency and continuity of the promotional work. BRIEF DESCRIPTION OF THE DRAWINGS
