Description

Technical Field

[0001] The utility model relates to the technical field of Bluetooth noise-cancelling earphones, in particular to an in-ear Bluetooth noise-cancelling earphone and a system. Background Art

[0002] In-ear headphones are headphones that are used inside the human auditory organ. According to their design, they will seal the user's ear canal when in use, reduce the impact of external noise, and provide a more perfect sound insulation effect and listening experience. Headphone noise reduction is generally divided into active noise reduction and passive noise reduction. The active noise reduction function is to generate reverse sound waves equal to the external noise through the noise reduction system to neutralize the noise, thereby achieving the noise reduction effect, while passive noise reduction is generally achieved through the headphone materials and structure.

[0003] For example, an in-ear noise-cancelling Bluetooth headset with application number CN201921319251.0 mainly includes an earphone shell, a hollow sound outlet, a silicone ear cap, etc. installed in sequence. A spherical cavity is provided in the earphone shell, and the spherical surface of the second end of the hollow sound outlet is placed in the spherical cavity. A movable ring is sleeved on the outer side of the earphone shell, and the movable ring squeezes the side wall of the spherical cavity and abuts against the spherical surface of the second end of the hollow sound outlet to fix the hollow sound outlet; the locking boss on the inner side of the movable ring is clamped and fixed with the mounting boss on the earphone shell. The utility model changes the abutment state of the earphone shell and the hollow sound outlet by rotating the movable ring, adjusts the angle of the hollow sound outlet, makes the silicone ear cap fit better with the ear canal, isolates external noise, and improves comfort; the speaker is installed in the hollow sound outlet and rotates synchronously with the hollow sound outlet to ensure smooth sound output. However, the in-ear Bluetooth noise-canceling headphones do not connect tightly to the ear canal, making them prone to falling off during exercise. Furthermore, sweat accumulates in the ears during exercise, resulting in poor performance. Furthermore, due to differences in ear and ear canal structure, the length of the headphones inserted into the ear canal cannot be adjusted, resulting in poor sound reception. Therefore, in light of these shortcomings, research and improvements were conducted to address the shortcomings of the existing structure, and an in-ear Bluetooth noise-canceling headphone was proposed. Utility Model Content

[0004] The purpose of the present invention is to provide an in-ear Bluetooth noise reduction headset and system to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned objectives, the present invention provides the following technical solution: an in-ear Bluetooth noise-canceling headset, comprising an outer shell and an adjustable ear hook, the top of the outer shell being fixedly connected to the adjustable ear hook, and the interior of the outer shell being fixedly connected to a battery, one side of the battery being fixedly connected to a Bluetooth module, and one side of the outer shell being fixedly connected to a fastening glue.

[0006] Preferably, one side of the fastening adhesive is fixedly connected to the inner shell, and a groove is provided inside the inner shell.

[0007] Preferably, a noise collecting block is fixedly connected to the interior of the groove, and a stretching mechanism is fixedly connected to one side of the groove.

[0008] Preferably, the stretching mechanism includes a fixed block fixedly connected to one side of the groove, and a stretching ring is fixedly connected to one side of the fixed block, a connecting frame is fixedly connected to one side of the stretching ring, and a dustproof net is fixedly connected to the inside of the connecting frame.

[0009] Preferably, one end of the connection frame is fixedly connected to a sleeve joint, and the outside of the sleeve joint is movably connected to a silicone earplug.

[0010] Preferably, a warning light is fixedly connected to the interior of the inner shell, a charging port is opened inside the inner shell, and a dust cover is movably connected to the interior of the charging port.

[0011] On the other hand, the in-ear Bluetooth noise reduction system of the present invention includes any of the above-mentioned in-ear Bluetooth noise reduction headphones.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. The utility model prevents the earphones from falling off when exercising with the noise-canceling headphones by setting the adjustable ear hook and the stretching mechanism. The inside of the adjustable ear hook has a pure cotton anti-skid pad, and the pure cotton anti-skid pad has strong sweat absorption, which prevents the earphones from falling off and can absorb sweat from the ears, increasing the comfort when wearing. Traditional noise-canceling headphones are not tightly connected to the ear canal, and are easy to fall off during exercise. In addition, sweat accumulates in the ears during exercise, resulting in poor use effect. Due to the differences in the structure of each person's ears and ear canals, the length of the earphones extending into the ear canal cannot be adjusted, resulting in poor sound reception. The adjustable ear hook of the utility model can be stretched and adjusted to a suitable wearing length according to different ear sizes. The internal fixing ring of the stretching mechanism connects the stretching mechanism to the groove. The stretching ring is multi-section. The stretching ring can be added or shortened as needed to adjust the silicone earplug to the appropriate distance from the ear canal, thereby improving the applicability of the noise-canceling headphones and increasing the comfort of the wearer. The dustproof net inside the connecting frame can prevent dust from entering the interior of the noise-canceling headphones and prevent dust from adhering to the surface of the components inside the noise-canceling headphones, affecting the normal use of electronic components.

[0014] 2. The utility model makes the connection between the outer shell and the inner shell more firmly through the provision of fastening glue and dust cover, so as to prevent the noise-canceling headphones from falling and the outer shell and inner shell from cracking, which will cause damage to the headphones. The fastening glue is acrylic ester, which is currently the most widely used dispensing glue. It has strong viscosity and is non-toxic, odorless, pollution-free and free of environmental pollutants after drying. It is suitable for dispensing fasteners of various materials. When the charging port is not in use, the dust cover can be covered on the outside of the charging port to prevent dust from entering the inside of the charging port and preventing dust accumulation from affecting the charging effect.

[0022] like Figure 3-Figure 4 As shown, one side of the fastening glue 5 is fixedly connected to the inner shell 6, and a groove 7 is provided inside the inner shell 6. The fastening glue 5 is made of acrylic resin, and the fastening glue 5 is evenly covered on the cross-section of the inner shell 6. The groove 7 supports the noise collecting block 8, and the noise collecting block 8 can reduce noise to the greatest extent.

[0023] Furthermore, a noise collecting block 8 is fixedly connected to the inside of the groove 7, and a stretching mechanism 9 is fixedly connected to one side of the groove 7. The stretching mechanism 9 includes a fixed block 901 fixedly connected to one side of the groove 7, and a stretching ring 902 is fixedly connected to one side of the fixed block 901, and a connecting frame 903 is fixedly connected to one side of the stretching ring 902.
