Description

Technical Field

[0001] The utility model relates to the technical field of English teaching loudspeakers, in particular to an anti-winding loudspeaker. Background Art

[0002] The loudspeaker was invented in 1950. It is not only limited to shouting machines. As the name suggests, it amplifies the sound and spreads it farther. Compared with speakers, the sound of loudspeakers is more penetrating. According to the way of use, it can be divided into wired loudspeakers and wireless loudspeakers. Due to the shape, size and speaker limitations, the uses vary. In existing English teaching, teachers often use smaller loudspeakers for teaching, usually hanging the loudspeaker around the waist to make both hands more free, thus freeing both hands for blackboard writing or other teaching operations.

[0003] The existing loudspeaker is usually carried on the body with a strap during use, making the loudspeaker easy to carry. However, when the strap is not needed, the long strap is often in a state of free swinging or entangled due to the lack of any storage device. When it is freely swinging, it is easy to cause damage by hooking and pulling. When it is entangled, it is time-consuming and inconvenient to use. Therefore, we propose an anti-entanglement loudspeaker. Utility Model Content

DETAILED DESCRIPTION

[0019] 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.

[0020] See also Figure 1-3 In this embodiment, an anti-winding loudspeaker comprises a loudspeaker body 1, a display 2 is fixedly connected to the front of the loudspeaker body 1, a horn 3 is fixedly connected to the front of the loudspeaker body 1, an operation key 4 is fixedly connected to the top of the loudspeaker body 1, an adjustment knob 5 is movably connected to the top of the loudspeaker body 1, a storage slot 6 is fixedly opened on the right side of the loudspeaker body 1, a wireless microphone 7 is movably connected inside the storage slot 6, and a reeling structure 12 is fixedly connected to the back of the loudspeaker body 1;

[0021] The rolling structure 12 includes a shell 1201, the back side of the loudspeaker body 1 is fixedly connected to the shell 1201, the interior of the shell 1201 is fixedly connected to a support rod 1202, the outer side of the support rod 1202 is fixedly connected to a turntable spring 1203, the interior of the shell 1201 is fixedly connected to an auxiliary rod 1204, the outer side of the auxiliary rod 1204 is movably connected to a restraining belt 1205, the left and right sides of the shell 1201 are fixedly connected to a storage compartment 1206, the right side of the storage compartment 1206 is movably connected to a buckle 1207, and the left side of the storage compartment 1206 is movably connected to a buckle compartment 1208.

[0022] During specific implementation, the clamping plate 11 is connected to the wireless microphone 7 through a spring rotating rod 10. The spring rotating rod 10 is composed of a connecting rod and a torsion spring. When the torsion spring is compressed or stretched, a rebound force is generated. The spring rotating rod 10 uses this rebound force to clamp or release the clamping plate 11 and the wireless microphone 7.

[0023] The turntable spring 1203 is made of sheet steel strip. When the restraint belt 1205 connected to the turntable spring 1203 is pulled out of the outer shell 1201, the turntable spring 1203 is wound tightly, and it will store elastic potential energy. As time goes by, when the turntable spring 1203 is gradually loosened, the stored potential energy is gradually released, which has the effect of tightening the restraint belt 1205.

[0024] When implementing, follow these steps:

[0025] 1) The teacher can pull the buckles 1207 and the buckle compartments 1208 on both sides of the shell 1201 along the outside of the waist and insert the buckles 1207 into the buckle grooves of the buckle compartments 1208. At this time, the buckles 1207 and the buckle compartments 1208 drive the two sets of restraint belts 1205 to move outward at the same time, and at the same time, the restraint belt 1205 drives one end of the turntable spring 1203 to move toward the storage compartment 1206. At this time, the first end of the turntable spring 1203 connected to the support rod 1202 is wound up, and it will store elastic potential energy. As time goes by, when the turntable spring 1203 is gradually loosened, the stored potential energy is gradually released, and at this time, the restraint belt 1205 has a tightening effect, so that the restraint belt 1205 is tightened around the teacher's waist;

[0026] 2) Then the wireless microphone 7 is taken out from the storage slot 6, and the clamping plate 11 is pressed so that the torsion spring is compressed or stretched to generate a rebound force. The spring rotating rod 10 utilizes this rebound force to clamp (at the collar) or release the clamping plate 11 and the wireless microphone 7;

[0027] 3) Restart the loudspeaker body 1, and it can be used efficiently without the restraint belt 1205 getting tangled.

[0028] To sum up, the anti-entanglement loudspeaker has a high winding efficiency by providing a winding structure 12, which can meet the needs of quickly and efficiently storing the restraint belt 1205, while avoiding the hidden danger of damage caused by hooking and pulling in the traditional technology where the restraint belt 1205 is often in a state of free swinging or difficult to entangle. At the same time, with the setting of the turntable spring 1203, the restraint belt 1205 has a tightening effect after the buckle 1207 and the buckle compartment 1208 are buckled, and the loudspeaker body 1 can be fixed on the waist in use, so that the teacher's hands can be used more freely, thereby freeing both hands to write on the blackboard or other teaching operations, thereby improving teaching efficiency.

[0029] Moreover, by providing the wireless microphone 7 and the magnetic strip 8, there is truly no need for connecting wires, it is easy to use, highly mobile, and at the same time has high sensitivity and can capture subtle sounds. In addition, the wireless microphone 7 also has an anti-howling function, which can effectively suppress the howling caused by feedback, solving the problem of easy entanglement of connecting wires and reduced teaching efficiency in traditional technologies. At the same time, the linkage design with the magnetic strip 8 makes the storage method more convenient.
