Description

Technical Field

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

[0002] Currently, there are many types of Bluetooth headphones, including over-ear Bluetooth headphones, which have certain advantages in sound quality and comfort. They usually have larger sound units and better audio performance, but they are relatively heavy and less portable, so they are often made in a foldable style.

[0003] Existing foldable Bluetooth headphones still have the following problems when in use: the folding part is easily damaged. The folding part often needs to run the connecting wires connecting the two earphone units. Frequent folding may cause material fatigue, wear or even breakage of the wires in the folding part. In addition, the folding structure may interfere with the internal acoustic structure and circuit layout of the headphones, resulting in a decrease in sound quality. Utility Model Content

[0024] Please see Figures 1-4 In this embodiment of the present invention, a foldable Bluetooth headset includes a headset unit mechanism 1, a headband mechanism 2 installed at the top of the headset unit mechanism 1, and two headset sound units 11 arranged symmetrically. Each of the two headset sound units 11 is equipped with a Bluetooth controller, and the two Bluetooth controllers are matched and connected wirelessly via Bluetooth. The overall design adopts an independent headset unit structure. The headset unit mechanism 1 includes two independent headset sound units 11, each equipped with an independent Bluetooth controller, and the two Bluetooth controllers are matched and connected wirelessly via Bluetooth. The headband mechanism 2 only serves as a mechanical connection between the two headset sound units 11, so there is no damage to the connecting wires at the folding point of the headband mechanism 2 or any impact on sound quality.

[0025] The headband mechanism 2 includes a connecting mechanism rotatably mounted on the outside of the headphone sound unit 11. The connecting mechanism includes an arc-shaped frame 21 rotatably connected to the outside of the headphone sound unit 11. A damping shaft seat 22 is fixedly mounted at the middle of the top of the arc-shaped frame 21. The headband mechanism 2 also includes a headband wearing mechanism. The headband wearing mechanism includes a connecting seat 23 threadedly mounted on the outside of the damping rotating end above the damping shaft seat 22. A U-shaped frame 24 is rotatably mounted on the outside of the connecting seat 23. An arc-shaped headband 25 is provided at the top of the two U-shaped frames 24. The headband mechanism 2 adopts a detachable structure design. It includes a headband wearing mechanism and a connecting mechanism between the headphone sound unit 11. The connecting mechanism and the headband wearing mechanism are connected by threads. It can be replaced when any mechanism is damaged. Therefore, it is not necessary to discard the entire headband mechanism 2 when any part of the headband mechanism 2 is damaged, thus saving maintenance costs.

[0026] The curved headband 25 has telescopic beams 26 on both sides. The telescopic beams 26 are fixedly connected to the U-shaped frame 24 on the corresponding side at the end away from the curved headband 25, which can adjust the length of the headband structure. The curved headband 25 is wrapped with cotton on the outside, and the bottom of the cotton wrap is fixedly connected with multiple anti-slip strips 27 in an arc shape at equal angles, which improves the wearing stability and comfort of the headband.

[0027] Two headphone sound units 11 face each other and each of them has multiple through holes 12 corresponding to the sound-producing elements inside. A sound-insulating cotton cover 13 is fixedly connected to the outer periphery of each of the two headphone sound units 11 facing each other, and a breathable mesh fabric 14 is fixedly connected to the inner periphery of each of the two headphone sound units 11 facing each other. While providing a comfortable wearing experience, it also serves to isolate external noise.

[0028] Two headphone sound units 11 are provided with wireless charging induction coils 18 at one end, which can wirelessly charge the two headphone sound units 11. Both headphone sound units 11 are provided with wired headphone connection interfaces 17 at the bottom center, which can be used for wired connection between the two headphone sound units 11.

[0029] A control switch 16 is provided on the front side of the bottom of the headphone speaker unit 11, which can control the switching on and off of the headphone speaker unit 11. A control button 15 is provided on the rear side of the bottom of the headphone speaker unit 11, which can adjust the working status of the headphone speaker unit 11.

[0030] The working principle of this utility model is as follows: the user can wear the Bluetooth headset through the headband mechanism 2, control the headphone sound unit 11 to work and produce sound through the control switch 16, and adjust the working state of the headphone sound unit 11 through the control button 15, thereby wearing and using the Bluetooth headset. The headphone unit mechanism 1 can be folded relative to the headband mechanism 2 by rotating the connecting seat 23 at the U-shaped frame 24. Since the whole adopts an independent headphone unit structure design, its headphone unit mechanism 1 includes two independent headphone sound units 11, each of which is equipped with an independent Bluetooth controller. The two Bluetooth controllers are matched and connected wirelessly via Bluetooth. The headband mechanism 2 only serves as a mechanical connection between the two headphone sound units 11. Therefore, there is no damage to the connecting wires at the folding point of the headband mechanism 2 or any impact on the sound quality.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
