[0002] Bluetooth headphones have become increasingly popular in sports, fitness, and commuting scenarios due to their portability and wireless advantages, and have become an important category in the headphone market.

[0003] Open-back headphones, with their open-ear design, allow sound to be transmitted directly to the ear canal without completely sealing it off. This provides clear sound quality while preserving ambient sounds, meeting users' needs for safety and ease of communication. For example, users can hear traffic sounds while running or hear colleagues while working. However, open-back headphones tend to have weaker sound quality and noise cancellation in noisy environments. Therefore, there is a need for open-back Bluetooth headphones that can improve both sound quality and noise cancellation. Utility Model Content

[0004] To address the aforementioned technical problems, this invention provides an open-back Bluetooth headset, which solves the technical issue that traditional open-back headsets have relatively weak sound quality and noise reduction capabilities in noisy environments.

[0005] The purpose and function of this utility model of an open-back Bluetooth headset are achieved by the following specific technical means:

[0013] According to a preferred embodiment, a mounting groove is provided on one side of the earphone shell, the Bluetooth connection module is installed in the mounting groove, and a second mounting hole is provided on the top of the earphone shell, and an ear hook is provided in the second mounting hole.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. By setting a detachable sound conduction component on one side of the open-ear shell, the sound conduction component can be removed during daily use, and the sound unit conducts sound directly to the ear canal through the open sound outlet, maintaining ambient sound perception. When it is necessary to use it in a noisy environment, one end of the guide tube is inserted into the first mounting hole, and the rubber earplug at the other end fits into the ear canal. At the same time, the first sealing plate around the guide tube drives the rubber sealing layer to cover the open sound outlet, blocking sound leakage from the open sound outlet and external noise intrusion. This allows the headphones to switch between open-ear and in-ear modes. In in-ear mode, the physical seal of the rubber earplug reduces external noise interference, improves the clarity of sound quality and bass performance, and solves the problem that the sound quality of traditional open-ear headphones is easily interfered with in noisy environments.

[0016] 2. Through the design of the sound conduction component, two sets of guide members are inserted into the guide groove through the through slot, and a second spring is set between the two sets of guide members. During installation, the guide members are inserted into the guide groove under the action of the spring force, ensuring a stable connection between the guide tube and the open earphone shell; during disassembly, press one end of the guide member to compress the second spring and disengage it from the guide groove, and the guide tube can be quickly removed, avoiding the cumbersome operation of traditional threaded or complex snap-fit ​​connections. Users can complete mode switching without tools.

[0017] 3. Through the setting of the rubber sealing layer, the rubber sealing layer around the guide tube is in close contact with the open sound outlet, forming a seal in the in-ear mode, reducing sound leakage and external noise infiltration; the waterproof and sound-permeable membrane inside the rubber earplug can prevent moisture and dust from entering the guide tube, while ensuring efficient sound transmission and avoiding sound quality loss; in addition, the second sealing plate cooperates with the first spring in the guide groove through the sliding block. After the sound transmission component is removed, the second sealing plate covers the first mounting hole under the action of the spring, so that the headphones are switched to open-back headphones, while preventing dust and other foreign objects from entering the headphones. This improves the noise reduction effect, protects the sound unit, and extends the service life of the headphones. Attached Figure Description

[0024] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0025] Example:

[0026] As attached Figure 1 To be continued Figure 4 As shown:

[0027] This utility model provides an open-back Bluetooth headset, including a headset shell 11, a Bluetooth connection module 12 installed inside the headset shell 11 for establishing a wireless connection with external devices such as mobile phones and computers, a sound-generating unit 14 disposed inside an open-back earbud shell 13 on one side of the headset shell 11, the sound-generating unit 14 being electrically connected to the Bluetooth connection module 12 via a wire, and converting the received audio signal into sound; a first mounting hole 22 on one side of the open-back earbud shell 13 is used to install a sound conduction component, one end of the guide tube 21 of the component being connected to the first mounting hole 22, and the other end being a rubber earbud 23 that can fit close to the ear canal, forming a switchable sound conduction path.

[0028] Please refer to, for example Figure 4 As shown, the open-back earbud shell 13 has multiple sets of open-back sound outlets 24 on one side. These open-back sound outlets 24 are distributed around the first mounting hole 22. When no sound conduction components are installed, the sound generated by the sound unit 14 is conducted directly to the ear canal through these sound outlets, while allowing ambient noise to enter, thus achieving an open-back listening effect. A first sealing plate 25 is provided around the guide tube 21. A rubber sealing layer 26 is provided on one side of the first sealing plate 25. One side of the rubber sealing layer 26 contacts the multiple sets of open-back sound outlets 24, forming a physical shield to prevent sound from leaking out of the sound outlets and to reduce external noise from entering the earphone through the sound outlets.

[0029] Specifically, during daily use, the sound transmission component is removed, and the sound from the sound-emitting unit 14 diffuses into the ear canal through the open sound outlet 24, allowing the user to simultaneously perceive ambient sounds. This is suitable for scenarios such as exercise and commuting where environmental awareness is required. When in a noisy environment, the guide tube 21 is inserted into the first mounting hole 22, and the rubber earplug 23 fits into the ear canal to form a semi-closed space. At the same time, the rubber sealing layer 26 of the first sealing plate 25 covers the open sound outlet 24, cutting off the open propagation path of the sound. This allows the sound to be conducted through the guide tube 21 to the rubber earplug 23. The fit between the earplug and the ear canal reduces noise infiltration, improves the focus of the sound and low-frequency performance, and meets the user's need for immersive listening.

[0030] Please refer to, for example Figure 3 and Figure 4As shown, the sound conduction assembly also includes two sets of guide frames 27, which provide an installation guide structure for the sound conduction assembly. Two sets of guide frames 27 are provided on one side of the first mounting hole 22. Guide grooves 28 are provided on the adjacent sides of the two sets of guide frames 27. A cover plate 29 is provided at one end of the guide frame 27 corresponding to the guide groove 28. Two sets of protruding through grooves 30 are provided on both sides of the guide tube 21. Two sets of guide members 31 are provided inside the guide tube 21. One end of the two sets of guide members 31 passes through the two sets of protruding through grooves 30 and is slidably connected to the two sets of guide grooves 28. The other end is slidably inserted into the other two sets of protruding through grooves 30. Through holes are provided on the adjacent sides of the two sets of guide members 31. A second spring 32 is provided between the two sets of through holes so that the two sets of guide members 31 maintain an outward expansion trend under the action of the spring force.

[0031] Specifically, when installing the sound conduction component, align the guide tube 21 with the first mounting hole 22. Under the elastic force of the second spring 32, the end of the guide member 31 is engaged in the guide groove 28 of the guide frame 27, forming a stable engagement structure to prevent the guide tube 21 from loosening and falling off during use. When it is necessary to remove the component, the user only needs to press the exposed end of the guide member 31 with their finger to move the guide member 31 inward and compress the second spring 32. After the end of the guide member 31 is disengaged from the guide groove 28, the guide tube 21 can be pulled out from the first mounting hole 22. The whole process does not require tools and is simple and quick to operate.

[0032] Please refer to, for example Figure 4 As shown, a second sealing plate 33 is provided between the two sets of guide frames 27. Sliding blocks 34 are provided on both sides of the second sealing plate 33. The two sets of sliding blocks 34 are slidably connected to the two sets of guide grooves 28 respectively. A first spring 35 is provided at the bottom of the two sets of guide grooves 28. One end of the two sets of first springs 35 is in contact with the two sets of sliding blocks 34 respectively.

[0033] Specifically, when the sound conduction component is installed in the first mounting hole 22, the guide tube 21 pushes the second sealing plate 33 to move inward, compressing the first spring 35. At this time, the second sealing plate 33 is stored between the guide brackets 27. When the sound conduction component is removed, the second sealing plate 33 automatically pops out under the action of the first spring 35, completely covering the first mounting hole 22, preventing dust, moisture and other foreign objects from entering the interior of the open earphone shell 13 through the mounting hole, and protecting the sound unit 14 and related circuits. At this time, the headphones return to a completely open state, and the sound of the sound unit 14 is normally conducted through the open sound outlet 24. Users can use the headphones in a clean and unobstructed structure, taking into account both ease of use and the protection requirements of internal components.

[0034] Please refer to, for example Figure 2As shown, two sets of locking blocks 36 are provided around the guide tube 21, and a slot is provided on one side of the rubber earplug 23. Both sets of locking blocks 36 can be detachably locked in the slot. A waterproof and sound-permeable membrane 37 is provided inside the rubber earplug 23 corresponding to the guide tube 21. The waterproof and sound-permeable membrane 37 covers the sound outlet end of the guide tube 21, which can prevent moisture and dust from entering the interior of the guide tube 21, and allow sound to pass through smoothly, maintaining good sound transmission effect. A mounting slot is provided on one side of the earphone shell 11, and the Bluetooth connection module 12 is installed in the mounting slot. A second mounting hole 15 is provided on the top of the earphone shell 11, and an ear hook 16 is provided in the second mounting hole 15, which can stably hang the earphone on the ear and improve the wearing stability.

[0035] Specifically, when the headphones are in in-ear mode, the rubber sealing layer 26 of the guide tube 21 fits against the open sound outlet 24, and together with the contact between the rubber earplug 23 and the ear canal, a double sealing structure is formed, which effectively reduces sound leakage to the outside world and reduces the interference of external noise on the listening effect. The waterproof and sound-permeable membrane 37 inside the rubber earplug 23 achieves a balance between physical protection and sound conduction, preventing contaminants such as liquids and dust from entering the inside of the headphones and damaging the sound unit 14, avoiding the sound quality degradation caused by the sealing structure, thereby improving the performance and extending the overall service life of the headphones.

Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
