Description

Technical Field

[0001] The utility model belongs to the technical field of hanging type loudspeakers used for classroom lectures in English teaching, and more specifically, particularly relates to hanging type loudspeakers. Background Art

[0002] In English teaching, a hanging loudspeaker is often used to amplify the voice of the teacher's lecture in the classroom, so that all students in the classroom can hear the teacher's voice. The existing hanging loudspeaker is usually composed of a wireless microphone, a speaker, an amplifying circuit device, a loudspeaker housing and a circuit power supply. The circuit power supply is responsible for providing electrical energy. The wireless microphone inputs the audio signal into the hanging loudspeaker, and then the amplifying circuit device converts the audio signal into an amplified electrical signal and outputs it to the speaker. The speaker converts the electrical signal into sound and propagates it, thereby amplifying the sound. The speaker, the amplifying circuit device and the circuit power supply are arranged inside the loudspeaker housing, a hook is provided above the loudspeaker housing, and a belt clip is provided on the side of the loudspeaker housing. When the hanging loudspeaker is not in use, the hook can be conveniently hung on the wall to save desktop space. When the hanging loudspeaker is in use, the belt clip can hook the loudspeaker housing on the belt, which is convenient for English teachers to carry with them when giving lectures.

[0003] The existing application number is: CN201220308354.9. A loudspeaker is usually used in public activities such as teacher teaching and outdoor speeches, and is mainly used to amplify the user's voice. It includes a loudspeaker housing and a belt clip. The belt clip consists of a connecting portion and a hooking portion for hooking on the user's waist belt. Both sides of the connecting portion are provided with convex wings. There are two strip-shaped protrusions on the loudspeaker housing. The opposite side walls of the two strip-shaped protrusions are provided with sliding grooves for the convex wings to be inserted. The loudspeaker housing between the two strip-shaped protrusions is provided with a convex rib, and the connecting portion is provided with a slot for the convex rib to be inserted. The utility model loudspeaker can ensure that the connecting portion of the belt clip is reliably connected to the loudspeaker housing.

[0004] Based on the above, in order to facilitate the use of the hanging loudspeaker, a belt clip is usually provided on the side of the loudspeaker housing. When the hanging loudspeaker is in use, the belt clip can hook the loudspeaker housing on the belt, which is convenient for English teachers to carry with them when giving lectures. The belt clip relies on its own elasticity to achieve the function of hooking the loudspeaker housing on the belt. When the thickness of the belt is large, the belt clip is prone to breakage or irreversible elastic deformation, causing damage to the belt clip. When the thickness of the belt is small, the belt clip is prone to shaking after clamping the belt, which is likely to cause the loudspeaker housing to shake and create the risk of the loudspeaker housing falling off. Therefore, when the hanging loudspeaker is in use, the belt clip on the side of the loudspeaker housing cannot be well hooked on belts of larger or smaller thicknesses, and is likely to cause damage to the belt clip or create the risk of the loudspeaker housing falling off.

[0082] When an English teacher uses a hanging loudspeaker in class, he needs to hook the square loudspeaker housing 1 on the belt. When in use, the side of the square loudspeaker housing 1 is placed close to the belt and moved downward. When the arc-shaped pressing claw 7 contacts the top of the belt, the arc-shaped pressing claw 7 stops moving downward, and the square loudspeaker housing 1 continues to slide downward under its own gravity. Therefore, the two sets of second gears 10 inside the square loudspeaker housing 1 will rotate.
