Description

Technical Field

[0001] The utility model relates to the field of loudspeaker structures, in particular to a loudspeaker structure for noise reduction headphones. Background Art

[0002] Headphones are a device that converts audio signals into sound. They can be worn on or placed around the ears, allowing users to receive audio content through their ears, such as music, voice, movie sounds, etc. Noise-canceling headphones refer to headphones that use physical or electronic means to eliminate or reduce noise. Noise-canceling headphones are headphones that have the function of reducing surrounding noise, which can be achieved through technologies such as active noise reduction or passive noise reduction.

[0003] Active noise-canceling headphones use microphones to collect ambient noise, and then generate sound waves with a phase opposite to the noise to offset the noise; passive noise reduction mainly reduces the entry of external sounds through physical isolation. Headphone speakers are the key components in headphones responsible for converting electrical signals into sound signals. The performance of headphone speakers directly affects the acoustic characteristics of the headphones, such as sound quality, volume, and frequency response. Headphone speakers of different types and qualities will differ in materials, structures, and manufacturing processes, which will lead to different sound performances.

[0004] However, the existing earphone speakers are not conducive to positioning the earphone speakers when in use. After using the earphone speakers for a long time, it will affect the use of the earphone speakers. It is also inconvenient to adjust the position of the earphone speakers, which will affect the applicable scope of the earphone speakers and is not conducive to the use of the earphone speakers.

[0005] Therefore, we propose a speaker structure for noise-canceling headphones. Utility Model Content

A screw 8 is rotatably installed in the middle of the surface on the side away from the speaker 4, and the screw 8 is threadedly connected to the middle of the second fixed plate 3. When used, it helps to position the speaker 4 in the speaker body 1. After using the speaker 4 in the speaker body 1 for a long time, it can prevent the speaker 4 in the speaker body 1 from being misplaced, which helps to use the speaker 4 in the speaker body 1. The position of the speaker 4 in the speaker body 1 can be conveniently adjusted to ensure the applicable range of use of the speaker 4 in the speaker body 1, which helps to use the speaker 4 in the speaker body 1.

[0033] Among them, the retention hole 14 passes through the two side surfaces of the middle part of the first fixed disk 2, and a porous mesh plate 16 is fixed on the side of the inner ring surface of the buckle 15 away from the first fixed disk 2. The outer ring surface of the porous mesh plate 16 and the corresponding position of the inner ring surface of the buckle 15 are in a matched and fitted state, and the porous mesh plate 16 can block and protect the inner side of the buckle 15; the screw 8 is in a horizontal state, and the first rotating disk 6 is fixed on the end surface of the screw 8 close to the movable disk 5. The first rotating disk 6 passes through the two side surfaces of the middle part of the movable disk 5, and the outer ring surface of the first rotating disk 6 is rotatably connected to the middle part of the movable disk 5 through a bearing. The first rotating disk 6 helps to limit the screw 8, which is convenient for stable rotation of the screw 8.

[0034] The screw 8 passes through the two side surfaces of the middle part of the second fixed disk 3, and the second rotating disk 7 is fixed to the end surface of the screw 8 away from the first rotating disk 6, and the side surface of the second rotating disk 7 away from the screw 8 is fixed with a rotating block 9. The rotating block 9 helps to rotate the second rotating disk 7, which is convenient for the use of the second rotating disk 7; a connecting ring 10 is rotatably installed on the outer side of the outer ring surface of the second rotating disk 7, and the inner ring surface of the connecting ring 10 is rotatably connected to the outer ring surface of the second rotating disk 7 through a bearing, and the connecting ring 10 is convenient for limiting the second rotating disk 7; a trapezoidal foldable cloth 11 is fixed to the edge part of the top of the side surface of the speaker body 1 away from the buckle 15, and the trapezoidal foldable cloth 11 is fixedly connected between the end of the trapezoidal foldable cloth 11 away from the speaker body 1 and the outer ring surface of the connecting ring 10, and the speaker body 1 can fix and limit the trapezoidal foldable cloth 11.

[0035] The trapezoidal foldable cloth 11 is located on the outside of the screw 8, and the trapezoidal foldable cloth 11 is sealed with the corresponding position on the speaker body 1, and the trapezoidal foldable cloth 11 is sealed with the corresponding position on the connecting ring 10. The trapezoidal foldable cloth 11 can block and protect the outside of the screw 8; blocks 12 are fixed on all four sides of the outer ring surface of the movable disk 5, and matching slots 13 are provided on all four sides of the inner ring surface of the top of the speaker body 1 corresponding to the blocks 12. The blocks 12 are slidably connected with the corresponding slots 13 on the speaker body 1 in the horizontal direction. The slots 13 and the blocks 12 help to limit the position between the speaker body 1 and the movable disk 5.

[0036] The working principle of the present utility model is: during use, the porous mesh plate 16 can block and protect the inner side of the buckle 15 to prevent dirt or foreign matter from entering the inner side of the buckle 15 and affecting use. When the position of the speaker 4 in the speaker body 1 needs to be moved and adjusted in the horizontal direction, the rotating block 9 is rotated. When the rotating block 9 rotates, it can drive the second rotating disk 7 to rotate. When the second rotating disk 7 rotates, it will rotate along the connecting ring 10. The connecting ring 10 helps to limit the second rotating disk 7. When the second rotating disk 7 rotates, it can drive the screw 8 to rotate. When the screw 8 rotates, it will move horizontally along the position where it is threadedly connected on the second fixed disk 3.

[0037] When the screw 8 moves in the horizontal direction, it can drive the second rotating disk 7 to move in the horizontal direction. When the second rotating disk 7 moves in the horizontal direction, it can drive the connecting ring 10 to move in the horizontal direction.

When the movable disk 5 moves in the horizontal direction, it can drive the block 12 to move horizontally along the slot 13 on the speaker body 1. The speaker body 1 can limit the movable disk 5 through the slot 13 and the block 12, which helps to stably move the movable disk 5.

[0038] When the movable plate 5 moves in the horizontal direction, it can drive the speaker 4 to be adjusted in the horizontal direction, so as to facilitate the horizontal movement and adjustment of the position of the speaker 4 in the speaker body 1. After the position adjustment of the speaker 4 is completed, when the speaker body 1 needs to be used, the noise reduction sleeve 17 is placed in the user's ear, and the speaker body 1 can make a sound through the speaker 4. The sound emitted by the speaker 4 can be transmitted to the user's ear through the retaining hole 14 on the first fixed plate 2, the buckle 15, the porous mesh plate 16 and the noise reduction sleeve 17, so that the user can listen. When the speaker 4 is used, the speaker body 1 can limit and position the speaker 4 through the card slot 13, the card block 12 and the movable plate 5, which is conducive to the stable use of the speaker 4.

[0039] During use, it helps to position the speaker 4 in the speaker body 1. After using the speaker 4 in the speaker body 1 for a long time, it can prevent the speaker 4 in the speaker body 1 from being misplaced, which helps to use the speaker 4 in the speaker body 1. The position of the speaker 4 in the speaker body 1 can be easily adjusted to ensure the applicable range of use of the speaker 4 in the speaker body 1, which helps to use the speaker 4 in the speaker body 1.
