Technical Field
[0001] This utility model relates to the field of Bluetooth headset technology, and in particular to a noise-canceling and interference-resistant Bluetooth headset device. Background Technology
[0002] Bluetooth headsets apply Bluetooth technology to hands-free devices, freeing users from the hassle of annoying wires and allowing them to make calls easily and freely in various ways. Since their advent, Bluetooth headsets have been a great tool for mobile business professionals to improve efficiency.
[0003] While most existing Bluetooth headphones offer some noise cancellation, there are still significant gaps between the ear pads and the ears when worn. These gaps allow external noise to easily pass through and enter the ear canal, resulting in weak noise cancellation. Furthermore, Bluetooth headphones are susceptible to electrical disturbances caused by external vibrations, making it difficult to effectively combat external electromagnetic interference and thus reducing their performance. Therefore, it is essential to design a noise-canceling and interference-resistant Bluetooth headphone. Utility Model Content
[0004] The main purpose of this utility model is to provide a noise-canceling and interference-resistant Bluetooth headset device, which can effectively solve the problems in the background art.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0006] An anti-noise and anti-interference Bluetooth headset includes a headband and an anti-interference shell. Ear cups are fixedly connected to both ends of the headband. Memory foam ear pads are provided on the inner side of the ear cups. An installation cavity is formed on the inner surface of the memory foam ear pads. A fixing half-ring is fixedly connected to the inner surface of the installation cavity. A PVC air ring is fixedly connected to the inner surface of the fixing half-ring. A one-way valve is formed on the outer surface of the fixing half-ring. A fixing groove is formed on the outer surface of the memory foam ear pads. A small suction cup is fixedly connected to one side of the outer surface of the PVC air ring. The small suction cup is movably connected to the fixing groove and is in communication with the PVC air ring.
[0007] To achieve good anti-interference capabilities, the anti-interference Bluetooth headset device of this utility model has a nickel-plated coating on the outer surface of the anti-interference shell, and a wave-absorbing material coating on the outer surface of the nickel-plated coating.
[0008] To make the anti-interference shell more durable, the outer surface of the wave-absorbing material coating of this utility model is ceramic coated.
[0009] To provide external sound insulation, as a noise-canceling and anti-interference Bluetooth headset device of this utility model, the inner wall of the anti-interference shell is fixedly connected with a Velcro adhesive surface, the inner wall of the anti-interference shell is provided with sound-insulating cotton, and the outer surface of the sound-insulating cotton is provided with a Velcro velvet surface, the Velcro velvet surface and the Velcro adhesive surface are bonded together.
[0010] To facilitate charging, as a noise-canceling and interference-resistant Bluetooth headset device of this utility model, a power button is provided on the outer surface of the ear cup, and a charging port is provided on one side of the outer surface of the ear cup.
[0011] Compared with the prior art, the present invention has the following beneficial effects:
[0012] 1. In this utility model, through the design of a headband, ear cups, PVC air rings, one-way valves, and small suction cups, when in use, the headband and ear cups are worn on the head. The headband provides a stable wearing experience, and the ear cups house the speakers and related electronic components. At this time, the memory foam ear pads contact the ears to provide an immersive audio experience. When a light pressure is applied to the ear cups, the memory foam ear pads receive pressure, causing the small suction cups inside the fixing grooves to contact the muscles around the ears. The one-way valve opens, and excess air in the PVC air rings is expelled. At this time, the small suction cups can form a certain suction force on the muscles around the ears to adhere to them, making the memory foam ear pads fit the ears more closely, thereby reducing the gap between them and the ears, reducing the transmission of external sounds, and increasing noise reduction performance.
[0013] 2. In this utility model, through the setting of anti-interference shell, nickel-plated coating, wave-absorbing material coating and sound-insulating cotton, the anti-interference shell is snapped onto the outside of the ear cup during use. The nickel-plated coating can provide good conductivity and electromagnetic shielding ability, which can effectively block external electromagnetic interference. Combined with the wave-absorbing material coating, it can absorb external electromagnetic waves, reduce electromagnetic wave reflection, and reduce signal interference. The ceramic coating can increase wear resistance. Combined with the sound-insulating cotton inside the anti-interference shell, it can reduce the external sound entering the ear canal while providing better anti-interference ability. In addition, the bonding relationship between the Velcro velvet side and the Velcro adhesive side on the sound-insulating cotton can facilitate the disassembly, assembly and replacement of the sound-insulating cotton, increasing its practicality.

The small suction cup 9 is movably connected to the fixing groove 8, and the small suction cup 9 is in communication with the PVC air ring 6.
[0027] In actual use, the headband 1 and ear cup 2 are worn on the head. The headband 1 provides a stable wearing experience, and the ear cup 2 houses the speakers and related electronic components. At this time, the memory foam ear pads 3 contact the ears to provide an immersive audio experience. Applying a light press to the ear cup 2 causes the memory foam ear pads 3 to receive pressure, which makes the small suction cups 9 inside the fixing groove 8 contact the muscles around the ears. The one-way valve 7 opens, and excess air in the PVC air ring 6 is expelled. At this time, the small suction cups 9 can form a certain suction force on the muscles around the ears to adhere to them, making the memory foam ear pads 3 fit the ears more closely, thereby reducing the gap between them and the ears, reducing the transmission of external sounds, and increasing noise reduction performance.
[0028] In this embodiment, the outer surface of the anti-interference protective shell 01 is provided with a nickel-plated coating 10, and the outer surface of the nickel-plated coating 10 is provided with a wave-absorbing material coating 11.
[0029] In practical use, the nickel-plated coating 10 can provide good conductivity and electromagnetic shielding capabilities, effectively blocking external electromagnetic interference. Combined with the wave-absorbing material coating 11, it can absorb external electromagnetic waves, reduce electromagnetic wave reflection, and reduce signal interference.
[0030] In this embodiment, the outer surface of the absorbing material coating 11 is covered with a ceramic coating 12.
[0031] In practical use, the ceramic coating 12 can increase the wear resistance of the anti-interference protective shell 01 and ensure its service life.

[0036] Working Principle: During use, the headband 1 and ear cups 2 are worn on the head. The headband 1 provides a stable fit, while the ear cups 2 house the speakers and related electronic components. The memory foam ear pads 3 then contact the ears to provide an immersive audio experience. Applying a light press to the ear cups 2 causes the memory foam ear pads 3 to absorb pressure, making the small suction cups 9 inside the retaining grooves 8 contact the muscles around the ears. The one-way valve 7 opens, expelling excess air from the PVC air ring 6. At this point, the small suction cups 9 create suction around the ears, allowing the memory foam ear pads 3 to fit more snugly against the ears, reducing gaps and minimizing external sound intrusion, thus increasing noise reduction and providing better sound insulation. The interference shield 01 is snapped onto the outside of the ear cup 2. The nickel-plated coating 10 provides good conductivity and electromagnetic shielding capabilities, effectively blocking external electromagnetic interference. Combined with the wave-absorbing material coating 11, it can absorb external electromagnetic waves, reduce electromagnetic wave reflection, and reduce signal interference. The ceramic coating 12 can increase the wear resistance of the interference shield 01 and ensure its service life. Combined with the sound-insulating cotton 14 inside the interference shield 01, it can reduce the external sound entering the ear canal while providing better anti-interference capabilities. Furthermore, the bonding relationship between the Velcro velvet side 15 and the Velcro adhesive side 13 on the sound-insulating cotton also facilitates the disassembly, assembly, and replacement of the sound-insulating cotton 14, increasing its practicality.
