Description

Technical Field

[0001] This utility model relates to the field of headphone technology, specifically a foldable headphone. Background Technology

[0002] Over-ear headphones offer better sound quality, more comfortable wear, and a more immersive experience, satisfying those with high demands for sound quality and comfort. However, the pursuit of improved comfort and sound quality has resulted in larger headphones, making them less portable. While some headphones are foldable, traditional folding headphone designs often lack an effective locking mechanism after adjusting the headband length and earcup angle. This can lead to loosening due to accidental contact during use, affecting stability and comfort. Furthermore, traditional headphones use elastic components to press the earcups against the outside of the ears, and excessive pressure can cause discomfort. Therefore, improvements to existing technology are needed. Utility Model Content

[0003] The purpose of this invention is to provide a foldable headphone that solves the problems of instability after folding and unfolding and excessive pressure on the ears, resulting in discomfort when worn.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a foldable headphone, comprising a crossbeam, with two symmetrically distributed telescopic frames slidably connected inside the crossbeam. A folding frame is hinged to the outside of the telescopic frame, and a headphone frame is hinged to the end of the folding frame away from the telescopic frame. Earcups are installed on the outside of the headphone frame. An angle positioning mechanism is provided on the folding frame. A fixing cover is fixedly connected to the upper end of the crossbeam. A double-bar frame is slidably connected inside the fixing cover. A snap-fit ​​frame is fixedly connected to the lower end of the double-bar frame, and a spring is provided on the outside of the bars of the double-bar frame.

[0005] Preferably, the fixed cover is slidably connected to the telescopic frame, and the snap-fit ​​frame is slidably connected to the fixed cover, allowing the telescopic frame to extend the length of the crossbeam.

[0006] Preferably, one end of the spring is fixedly connected to the fixing cover, and the other end of the spring is fixedly connected to the snap-fit ​​bracket. The spring can support the snap-fit ​​bracket with its elastic force.

[0007] Preferably, the upper end of the telescopic frame is provided with a positioning groove, which engages with the snap-fit ​​frame, allowing the snap-fit ​​frame to position the telescopic frame through the positioning groove.

[0008] Preferably, the angle positioning mechanism includes a positioning gear, the positioning gear is fixedly connected inside the folding frame, a guide pin is fixedly connected inside the telescopic frame, a toothed plate is fixedly connected to the outside of the guide pin, and a spring is provided on the outside of the guide pin. The guide pin can guide the movement of the toothed plate.

[0009] Preferably, the toothed plate is slidably connected to the telescopic frame, and the toothed blocks of the toothed plate engage with the tooth grooves of the positioning gear. The toothed plate can position the folding frame through the positioning gear.

[0010] Preferably, one end of the second spring is fixedly connected to the telescopic frame, and the other end of the second spring is fixedly connected to the toothed plate. The second spring can support the toothed plate with its elastic force.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] 1. This utility model adds a telescopic frame, a snap-fit ​​frame, and a fixing cover to the crossbeam. After the telescopic frame is adjusted by sliding inside the crossbeam, the snap-fit ​​frame can be driven by the elastic force of the spring to slide into the positioning groove of the telescopic frame, thereby locking the telescopic frame and effectively improving the stability of the telescopic frame after adjustment.

[0013] 2. This utility model adds a guide pin, a toothed plate, and a positioning gear inside the telescopic frame. During use, the toothed plate can be driven by the elastic force of the second spring to engage with the tooth groove of the positioning gear, thereby positioning the positioning gear and the folding frame. This avoids the elastic component supporting the ear bag and prevents excessive clamping. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-6 A foldable headphone includes a crossbeam 1, with two symmetrically distributed telescopic frames 2 slidably connected inside the crossbeam 1. A folding frame 3 is hinged to the outside of the telescopic frame 2. A headphone frame 4 is hinged to the end of the folding frame 3 away from the telescopic frame 2. Earcups 5 are installed on the outside of the headphone frame 4. An angle positioning mechanism 6 is provided on the folding frame 3. A fixing cover 7 is fixedly connected to the upper end of the crossbeam 1. A double rod frame 8 is slidably connected inside the fixing cover 7. A snap-fit ​​frame 9 is fixedly connected to the lower end of the double rod frame 8. A spring 10 is provided on the outside of the rods of the double rod frame 8.

[0023] Please see Figure 1-6 The fixed cover 7 is slidably connected to the telescopic frame 2, and the snap-fit ​​frame 9 is slidably connected to the fixed cover 7. The telescopic frame 2 can extend the length of the crossbeam 1. One end of the spring 10 is fixedly connected to the fixed cover 7, and the other end of the spring 10 is fixedly connected to the snap-fit ​​frame 9. The spring 10 can support the snap-fit ​​frame 9 through its elastic force. The upper end of the telescopic frame 2 is provided with a positioning groove 11, which snaps into the snap-fit ​​frame 9. The snap-fit ​​frame 9 can position the telescopic frame 2 through the positioning groove 11.

[0024] Please see Figure 1-6The angle positioning mechanism 6 includes a positioning gear 61. The positioning gear 61 is fixedly connected inside the folding frame 3. The guide pin 62 is fixedly connected inside the telescopic frame 2. A toothed plate 63 is fixedly connected to the outside of the guide pin 62. A spring 64 is provided on the outside of the guide pin 62. The guide pin 62 can guide the movement of the toothed plate 63. The toothed plate 63 is slidably connected to the telescopic frame 2. The toothed blocks of the toothed plate 63 are engaged with the tooth grooves of the positioning gear 61. The toothed plate 63 can position the folding frame 3 through the positioning gear 61. One end of the spring 64 is fixedly connected to the telescopic frame 2, and the other end of the spring 64 is fixedly connected to the toothed plate 63. The spring 64 can support the toothed plate 63 through its elasticity.

[0025] The specific implementation process of this utility model is as follows: When in use, the ear bag 5 is flipped downwards and made vertical, and then the double rod frame 8 is pulled. The double rod frame 8 drives the snap-fit ​​frame 9 to move and compresses the spring 10. When the snap-fit ​​frame 9 is disengaged from the positioning groove 11, the limitation on the telescopic frame 2 can be released. Then the position of the telescopic frame 2 is adjusted. After the adjustment is completed, the double rod frame 8 is released and the spring 10 is reset. The spring 10 can drive the snap-fit ​​frame 9 to slide into the positioning groove 11 through the elastic force, which can lock the telescopic frame 2 and make the adjustment more stable.

[0026] Then, while placing the earcups 5 on the outside of the ears, place the crossbeam 1 on the top of the head, and then push the folding frame 3. During the deflection process, the folding frame 3 can push the toothed plate 63 to move through the positioning gear 61. During the movement, the toothed plate 63 can compress the second spring 64. When the deflection angle of the folding frame 3 is appropriate, the second spring 64 returns to its original position. The second spring 64 can drive the teeth of the toothed plate 63 to slide into the tooth groove of the positioning gear 61 through the elastic force, thus completing the wearing of the headphones.
