Technical Field
[0001] The utility model belongs to the technical field of Bluetooth headsets, and particularly relates to a semi-noise reduction structure of a Bluetooth headset based on a gyroscope. Background Technique
[0002] A Bluetooth headset applies Bluetooth technology to a hands-free headset, allowing users to get rid of the annoying wires and freely listen to music and make calls in various ways. Since the advent of Bluetooth headsets, their advantages such as convenience and compactness have been deeply loved by users, and their usage range is getting wider and wider. Bluetooth technology is globally open and has good compatibility globally. The whole world can be connected into one body through a low-cost invisible Bluetooth network.
[0003] However, there are some problems in the prior art: for existing clip-on Bluetooth headsets, users can clip them on their ears for wearing, making the sound holes located in the cochlea but not completely blocking the ear canal. Thus, users can still hear the sounds on the road when wearing the headset while walking or cycling. However, when users are in a noisy indoor environment such as a station, the headset cannot change the wearing method to block the ear canal to achieve noise reduction, thereby reducing the applicability. Therefore, we propose a semi-noise reduction structure of a Bluetooth headset based on a gyroscope. Content of the Utility Model
[0004] Aiming at the problems existing in the prior art, the purpose of the utility model is to provide a semi-noise reduction structure of a Bluetooth headset based on a gyroscope, which can meet the better use of users in different environments through an adjustable wearing method.
[0005] The utility model is realized as follows: a semi-noise reduction structure of a Bluetooth headset based on a gyroscope includes a first shell and a second shell. The first shell and the second shell are hinged through a rotating shaft. A gyroscope sensor is fixedly installed in the inner cavity of the second shell. A notch is opened on the second shell. An arc-shaped plate is fixedly connected to the first shell, and the other end of the arc-shaped plate extends into the notch. A limiting mechanism is arranged on the second shell below the arc-shaped plate, and the second shell can be fixed through the limiting mechanism after rotation.
[0006] Optionally, a square groove is opened at the bottom of the first shell, and a circular groove is opened at the bottom of the arc-shaped plate. The limiting mechanism includes a fixed block fixedly installed on the second shell. A pin is movably inserted into the fixed block. The top of the pin extends into the circular groove, and the bottom of the pin is fixedly connected to a pressing plate.
[0007] Optionally, a spring is movably sleeved on the outer surface of the pin, and the two ends of the spring are respectively fixedly connected to the fixed block and the pressing plate.
[0008] Optionally, gaskets are fixedly installed on both the first housing and the second housing, and a sheath is movably sleeved on one end of the first housing away from the rotating shaft.
[0009] Optionally, the number of the gaskets is two, and anti-slip patterns are provided on the surfaces of both gaskets.
[0010] Optionally, a second magnet block is fixedly installed at the bottom of the first housing, and a first magnet block is fixedly installed on the second housing above the fixed block.
[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0012] By providing the second housing, the rotating shaft and the arc plate, when in use, the user can rotate the first housing and the second housing through the rotating shaft, so that the arc plate is drawn out from the slot, and then the earphone is clamped and worn on the ear, so that the sound holes on the first housing are located in the cochlea but do not completely block the ear canal. Therefore, the user can still hear the sounds on the road when wearing the earphone while walking or cycling, which is safer. When in a noisy indoor environment, the user can rotate the second housing to insert the arc plate into the slot, as Figure 4 shown, and then insert the end of the first housing into the ear to block the ear canal. At the same time, after the deflection angle of the gyroscope sensor exceeds the set threshold angle, the earphone turns on the in-ear noise reduction mode, meeting the user's needs in different environments.
[0013] Other features and advantages of the present utility model will become clear through the following detailed description of the exemplary embodiments of the present utility model with reference to the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] To further understand the content, features and effects of the present utility model, the following embodiments are exemplified and described in detail in conjunction with the accompanying drawings.
[0021] As Figures 1 to 5 shown, a semi-noise reduction structure of a Bluetooth headset based on a gyroscope provided by an embodiment of the present utility model includes a first housing 1 and a second housing 2. The first housing 1 and the second housing 2 are hinged through a rotating shaft 3. A gyroscope sensor 4 is fixedly installed in the inner cavity of the second housing 2. A notch 5 is opened on the second housing 2. An arc plate 6 is fixedly connected to the first housing 1, and the other end of the arc plate 6 extends into the notch 5. A limiting mechanism is arranged on the second housing 2 below the arc plate 6. After the second housing 2 rotates, it can be fixed through the limiting mechanism.
[0022] Furthermore, a square groove 7 is opened at the bottom of the first housing 1, and a round groove 8 is opened at the bottom of the arc plate 6. The limiting mechanism includes a fixed block 9 fixedly installed on the second housing 2. A plug 10 is movably inserted into the fixed block 9. The top of the plug 10 extends into the round groove 8, and the bottom of the plug 10 is fixedly connected to a pressure plate 11.
[0023] By inserting the plug 10 into the round grooves 8 at different positions, the second housing 2 can be limited at different positions, so as to adjust the included angle between the second housing 2 and the first housing 1, so that the first housing 1 and the second housing 2 can adjust different tightness when clamped on the ear, so as to meet the needs of different users.
[0024] Furthermore, a spring 12 is movably sleeved on the outer surface of the plug 10, and both ends of the spring 12 are fixedly connected to the fixed block 9 and the pressure plate 11 respectively.
[0025] By setting the spring 12 in a stretched state, due to the elastic recovery of the spring 12, the plug 10 will tend to move upward, so that the plug 10 can be stably held inside the round groove 8.
[0026] Furthermore, gaskets 13 are fixedly installed on both the first housing 1 and the second housing 2, and a sheath 14 is movably sleeved on one end of the first housing 1 away from the rotating shaft 3.
[0027] Both the gasket 13 and the sheath 14 can be made of silica gel, making it more comfortable for users to wear. Moreover, the sheath 14 fits tightly with the first housing 1 through elastic force, and users can replace the sheath 14 with different models according to the size of the cochlea to meet their own usage habits.
[0028] Furthermore, the number of gaskets 13 is two, and anti-slip patterns are provided on the surfaces of both gaskets 13.
[0029] Furthermore, a second magnet block 16 is fixedly installed at the bottom of the first housing 1, and a first magnet block 15 is fixedly installed on the second housing 2 above the fixed block 9.
[0030] After the second housing 2 drives the first magnet block 15 to rotate, the first magnet block 15 can be brought into contact with the second magnet block 16. By setting the magnetic poles of the first magnet block 15 and the second magnet block 16 to be opposite, the magnetic adsorption between the first magnet block 15 and the second magnet block 16 can fix the second housing 2.
[0031] When in use, the user can rotate the first housing 1 and the second housing 2 through the rotating shaft 3 to pull out the arc-shaped plate 6 from the notch 5. At the same time, the plug 10 is inserted into the circular groove 8 to limit the position of the second housing 2, so as to clamp and wear the earphone on the ear, making the sound hole on the first housing 1 located in the cochlea but not completely blocking the ear canal. Thus, the user can still hear the sounds on the road when wearing the earphone while walking or cycling, which is safer. In a noisy indoor environment, the user can rotate the second housing 2 to insert the arc-shaped plate 6 into the notch 5, as Figure 4 shown. Then, after rotating a certain angle, the end of the first housing 1 is inserted into the ear to block the ear canal. At the same time, when the deflection angle of the gyroscope sensor 4 exceeds the set threshold angle, the earphone turns on the in-ear noise reduction mode to meet the user's usage in different environments.
[0032] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
