Description

Technical Field

[0001] This utility model relates to the field of Bluetooth headset technology, specifically to low-latency wireless stereo Bluetooth headsets. Background Technology

[0002] Bluetooth headphones, as a representative of modern wireless audio devices, have become a common daily device for the public due to their convenience and technological sophistication. They have solved the problems of wired headphones being inconvenient to carry and causing interference during use, thus improving the ease of use of headphones. However, during use, Bluetooth headphones are easily affected by external interference, which can affect their stability and cause connection delays.

[0003] To overcome the aforementioned shortcomings, existing technology (Chinese patent application CN202021631570.8, application date 20200807) provides a low-latency Bluetooth headset. This headset utilizes a wireless Bluetooth transmitter mounted on it, with paired RX / TX chips from the same company in both the headset and the transmitter. This significantly reduces latency during audio transmission and reception. Furthermore, the transmitter can connect to different electronic devices, allowing the headset to adapt to various devices. The transmitter can also pair with multiple headsets simultaneously, enabling multi-user synchronization and greatly enhancing the user experience. While existing technology achieves low-latency connectivity, it is inconvenient to reduce Bluetooth connection latency during operation, affecting connection quality, especially when multiple electronic devices are present, and potentially impacting the stereo sound of the Bluetooth headset.

[0004] To address the aforementioned issues, there is an urgent need for innovative designs based on existing Bluetooth headsets. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: a low-latency wireless stereo Bluetooth headset, comprising a headphone body designed for easy wearing, with a headphone shell rotatably connected to the lower side of the headphone body; including: earcups nested within the inner surface of the headphone shell, with a player nested within the inner surface of the headphone shell, and a limiting component installed on the inner surface of the headphone shell, the limiting component also having a limiting locking mechanism; a Bluetooth chip soldered onto a circuit board assembled with the headphone shell, with connecting wires installed on the outer surface of the circuit board, and a movable plate installed on the outer surface of the connecting wires, the movable plate also having a pressing and sliding mechanism.

[0007] Preferably, the earcups and the headphone shell form a nested structure, the headphone shell and the player form an internal structure, and the headphone shell and the limiting component form an integrated structure.

[0008] The above structure facilitates effective nesting during use and allows for stereo surround sound playback when combined with different groups of players, thereby improving the playback effect.

[0009] Preferably, the limiting engagement mechanism includes a card that is slidably connected to the inner surface of the limiting component, and a handle is installed on the outer surface of the card. A return spring is elastically connected between the card and the limiting component, and a circuit board is limitedly connected between the card and the earphone shell. The limiting component forms an elastic engagement structure with the circuit board through the return spring and the card.

[0010] The above structure effectively controls the stability of the circuit board during use and reduces loosening between lines, thus avoiding interference with playback and Bluetooth connection control.

[0011] Preferably, the Bluetooth chip and the circuit board form a welded structure, the circuit board and the connecting line form a mating structure, and the connecting line and the moving board form a nested structure.

[0012] The above structure improves connection stability during use and, in conjunction with an adjustable movable plate, allows for signal amplification in the later stages, reducing connection delay.

[0013] Preferably, the compression sliding mechanism includes a limiting frame slidably assembled on the outer surface of the moving plate, and the limiting frame is installed on the inner surface of the earphone shell. A second return spring is elastically connected between the limiting frame and the moving plate. At the same time, a signal amplification line is installed on the outer surface of the moving plate, and the moving plate forms an elastic structure with the limiting frame through the second return spring.

[0014] With the above structure, the signal amplification line assembled on the movable board can be used to improve the signal connection, reduce latency, and increase connection stability during use.

[0015] Preferably, a protective plate is slidably connected to the inner surface of the earphone shell, and a pressing rod is installed on the outer surface of the protective plate. The pressing rod passes through the limiting frame and the lower side of the outer surface of the pressing rod is pressed and connected to the side of the outer surface of the moving plate. At the same time, a tension spring is elastically connected between the pressing rod and the earphone shell. The protective plate and the earphone shell form an elastic tension structure through the pressing rod and the tension spring, and the pressing rod and the moving plate form a pressing structure through the limiting frame.

[0016] With the above structure, during use, it can be used in conjunction with the moving limiting squeeze to open the protective plate while simultaneously pushing out the signal amplification line inside the earphone shell, thereby improving signal connection stability and low signal connection latency.

[0017] Preferably, the inner surface of the protective plate is engaged with a limiting member, and a return spring is elastically connected between the limiting member and the earphone shell, and the limiting member and the protective plate form a limiting engagement structure.

[0018] The above structure effectively improves the stability of the protective plate after adjustment during use and prevents the protective plate from automatically resetting when using headphones.

Furthermore, when used with the player and earcups assembled in the headset shell, it enhances the stereo playback effect under low latency.

[0022] 3. This low-latency wireless stereo Bluetooth headset is equipped with a squeezing and sliding mechanism. When using the Bluetooth headset, the protective plate can be slid open, thereby driving the squeezing rod to control the position of the moving plate on which the connecting cable is installed and adjusting the sliding out of the signal amplification cable to improve the signal connection effect. The mechanism is also used through a second reset spring for the later retrieval of the signal amplification cable, improving its protection effect. Furthermore, the limiting component connected by the third reset spring allows the protective plate to be effectively limited and locked after movement, preventing interference with signal amplification during normal use.

[0030] 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.

[0031] Please see Figures 1-6 The present invention provides the following technical solution: a low-latency wireless stereo Bluetooth headset, wherein a headset body 1 is designed for easy wearing, and a headset shell 2 is rotatably connected to the lower side of the headset body 1.

[0032] Example 1: As Figures 1-3 The technical solution shown is provided by this utility model as follows: a low-latency wireless stereo Bluetooth headset, comprising: earcups 3, nested on the inner surface of a headphone shell 2, and a player 4 is nested on the inner surface of the headphone shell 2, and a limiting component 5 is installed on the inner surface of the headphone shell 2, and the limiting component 5 is provided with a limiting engagement mechanism; the earcups 3 and the headphone shell 2 form a nested structure, and the headphone shell 2 and the player 4 form an internal structure, and the headphone shell 2 and the limiting component 5 form an integrated structure.

[0033] When using Bluetooth headphones, the earcups 3, which are installed on the headphone shell 2 assembled through the headphone body 1, come into contact with the user's ears and cover the ears with the earcups 3. The Bluetooth headphones are then connected to the corresponding devices, and multiple players 4, which are equidistantly arranged inside the headphone shell 2, play sound, thereby increasing the stereo effect of the Bluetooth headphones and improving the user experience.

[0034] Example 2: Figure 1 , Figure 2 and Figure 4 The technical solution shown, based on Embodiment 1, further discloses a method to reduce the loosening and damage of the circuit board 9 assembled with the Bluetooth chip 10. The specific details are as follows: The Bluetooth chip 10 is soldered onto the circuit board 9 assembled with the earphone shell 2. A connecting line 11 is mounted on the outer surface of the circuit board 9, and a movable plate 12 is mounted on the outer surface of the connecting line 11. The movable plate 12 is equipped with a pressing and sliding mechanism. The limiting engagement mechanism includes a locking piece 7 slidably connected to the inner surface of the limiting component 5. A handle 6 is mounted on the outer surface of the locking piece 7, and a return spring 8 is elastically connected between the locking piece 7 and the limiting component 5. The circuit board 9 is also limitedly connected between the locking piece 7 and the earphone shell 2. The limiting component 5, through the return spring 8 and the locking piece 7, forms an elastic engagement structure with the circuit board 9. The Bluetooth chip 10 and the circuit board 9 form a soldered structure, the circuit board 9 and the connecting line 11 form a mating structure, and the connecting line 11 and the movable plate 12 form a nested structure.

[0035] During signal connection, the connecting cable 11 assembled via the movable board 12, the circuit board 9 mounted on the connecting cable 11, and the Bluetooth chip 10 assembled on the circuit board 9 process the connected signal to improve the stability of the signal transmission. The limiting component 5 mounted on the earphone shell 2 limits the circuit board 9 to the inside of the earphone shell 2 by positioning pins during assembly. The limiting component 5, along with the retaining clip 7 elastically squeezed by the return spring 8, elastically engages the retaining clip 7 on the outside of the circuit board 9, improving the stability of the circuit board 9 assembly and preventing it from loosening. The handle 6 mounted on the retaining clip 7 facilitates disassembly and replacement of the circuit board 9 when it suffers natural damage.

[0036] Example 3: Figure 1 , Figure 2 , Figure 5 and Figure 6The technical solution shown, based on Embodiment 2, further discloses the usage of the signal amplification line 15, the specific details of which are as follows: The compression sliding mechanism includes a limiting frame 13 slidably assembled on the outer surface of the moving plate 12, and the limiting frame 13 is installed on the inner surface of the earphone shell 2. A return spring 14 is elastically connected between the limiting frame 13 and the moving plate 12. At the same time, the signal amplification line 15 is installed on the outer surface of the moving plate 12, and the moving plate 12 and the limiting frame 13 form an elastic structure through the return spring 14. A protective plate 16 is slidably connected to the inner surface of the earphone shell 2, and a compression rod 1 is installed on the outer surface of the protective plate 16. 7. The extrusion rod 17 passes through the limiting frame 13 and the lower side of the outer surface of the extrusion rod 17 is extruded and connected to the side of the outer surface of the moving plate 12. At the same time, a tension spring 18 is elastically connected between the extrusion rod 17 and the earphone shell 2. The protective plate 16 forms an elastic tension structure with the earphone shell 2 through the extrusion rod 17 and the tension spring 18. The extrusion rod 17 forms an extrusion structure with the moving plate 12 through the limiting frame 13. The inner surface of the protective plate 16 is engaged with the limiting member 19. A return spring 20 is elastically connected between the limiting member 19 and the earphone shell 2. The limiting member 19 and the protective plate 16 form a limiting engagement structure.

[0037] When using the Bluetooth headset, the control protective plate 16 slides within the headset shell 2. Simultaneously, the protective plate 16 moves the installed pressing rod 17 upwards, passing through the limiting frame 13 assembled within the headset shell 2. The pressing rod 17, through its protrusion, presses against the sliding plate 12 slidably connected within the limiting frame 13. This causes the sliding plate 12 to press against the second return spring 14, and moves the signal amplification line 15, assembled on the sliding plate 12 and mounted on the connecting wire 11, outwards. This improves the signal connection effect and reduces signal delay through the signal amplification line 15. Furthermore, after the protective plate 16 moves, it will cooperate with the protective... Plate 16 is stably engaged with the limit member 19 of the reset spring 20, which increases the stability of the Bluetooth headset signal connection with low latency after the protective plate 16 moves. When the Bluetooth headset is not in use, the limit member 19 is retracted into the headset shell 2, the protective plate 16 is disengaged from the engagement limit, and the protective plate 16 is reset by the elastic stretching of the tension spring 18 assembled with the compression rod 17. In addition, the moving plate 12, in conjunction with the reset spring 14, drives the signal amplification line 15 to retract in advance. When the protective plate 16 is continuously moved downward, it is used for protection when not in use, which improves the safety of use and the effect of low latency.

[0038] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
