Technical Field

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

[0002] The noise reduction of Bluetooth headsets is divided into active noise reduction and passive noise reduction. Active noise reduction 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. Passive noise reduction is mainly achieved by surrounding the ears to form a closed space, or using sound insulation materials such as silicone ear caps to block external noise.

[0003] The utility model with the existing authorization application number CN216960151U discloses an in-ear noise-reducing Bluetooth headset, including a shell, wherein an earplug connecting part is integrally formed on one side of the shell, an earplug is detachably connected to the earplug connecting part, an ear cap is provided at the sound outlet end of the earplug, and a sound insulation structure is provided on the earplug between the ear cap and the earplug connecting part.

[0004] By adopting the above technical solution, double isolation of noise outside the user's ear canal is achieved. However, with the above technical solution, when the device is in use, since the size of the sound insulation structure is fixed, when different users use the device, it is easy for the sound insulation structure to not fully seal the user's ear canal, which results in different noise reduction effects for different users, reducing the practicality of the device.

[0024] In order to better understand the purpose, structure and function of the present invention, the following is a further detailed description of an in-ear noise-cancelling Bluetooth headset of the present invention in conjunction with the accompanying drawings.

[0025] See also Figure 1-5 The utility model discloses an in-ear noise-reducing Bluetooth headset, comprising an earphone body 1, an earplug connecting tube 2 and an air pump 4. One end of the earplug connecting tube 2 close to the earphone body 1 is fixedly connected to the front of the earphone body 1, and the back of the air pump 4 is fixedly connected to the inner wall of the earphone body 1. The input end of the air pump 4 power passes through the earphone body 1 and extends to the outside of the earphone body 1. A rubber pad 10 is fixedly installed on the left side of the earphone body 1. The left side of the rubber pad 10 is provided with anti-slip grooves 11 arranged at equal distances. The installation of the rubber pad 10 and the anti-slip grooves 11 increases the friction between the user and the earphone body 1 when the user picks up the earphone body 1, thereby avoiding the earphone body 1 from slipping and breaking as much as possible.

[0026] An airbag 3 is fixedly installed on the outer surface of the earplug connecting tube 2, and an air outlet pipe 16 is fixedly connected to the back of the airbag 3. An electromagnetic valve 17 is fixedly installed on the outer surface of the air outlet pipe 16. The installation of the air outlet pipe 16 and the electromagnetic valve 17 makes it convenient for the user to discharge the gas inside the airbag 3, thereby reducing the volume of the airbag 3.

[0027] The output end of the air pump 4 power is fixedly connected to a hose 5, and the end of the hose 5 away from the air pump 4 passes through the airbag 3 and extends to the inside of the airbag 3. A power button 18 is fixedly installed on the right side of the earphone body 1, and a multi-function button 19 is fixedly installed on the right side of the earphone body 1. The installation of the power button 18 makes it convenient for the user to control the switch of the Bluetooth headset. The installation of the multi-function button 19 allows the user to realize different functions such as starting electronic components, changing songs and connecting calls by pressing different times.

[0028] A rubber sleeve 6 and two electric push rods 7 are fixedly installed on the outer surface of the earplug connecting tube 2. The extension and retraction directions of the two electric push rods 7 are opposite. A battery 12 is fixedly installed on the inner wall of the earphone body 1. The battery 12 is electrically connected to the earphone body 1, the air pump 4, the electric push rods 7 and the solenoid valve 17 through wires. The installation of the battery 12 can provide electrical energy to the electrical equipment of the device, so that the device does not need to be limited by the length of the wires, thereby increasing the practicality of the device.

[0029] Two expansion pieces 8 are arranged inside the rubber sleeve 6, and the side surfaces of the two expansion pieces 8 close to each other are fixedly connected to the two ends of the electric push rod 7 respectively, and the outer surface of each expansion piece 8 is in contact with the inner wall of the rubber sleeve 6. Two charging ports 14 are arranged on the bottom surface of the earphone body 1, and a conductive piece 15 is fixedly installed on the inner wall of each charging port 14. The conductive piece 15 is electrically connected to the battery 12 through a wire, so that when the user places the Bluetooth headset in the charging compartment, the conductive column inside the charging compartment is inserted into the charging port 14 and in contact with the conductive piece 15, thereby charging the battery 12.

[0030] Two sets of connecting springs 9 are fixedly installed on the side where the two expansion pieces 8 are close to each other. A telescopic rod 13 is sleeved inside each connecting spring 9. The end of each telescopic rod 13 that is away from each other is fixedly connected to the side where the two expansion pieces 8 are close to each other. The installation of the telescopic rod 13 plays a role in limiting the moving trajectory of the expansion pieces 8, thereby minimizing the phenomenon that the expansion pieces 8 deviate from the moving trajectory when moving, thereby ensuring the stability of the movement of the expansion pieces 8.

[0031] The back of the earphone body 1 is provided with heat dissipation vents 20 arranged at equal distances, and a dustproof net 21 is fixedly installed on the back of the earphone body 1. The opening of the heat dissipation vents 20 increases the air flow inside the earphone body 1, thereby reducing the temperature of the Bluetooth earphone during operation. The installation of the dustproof net 21 prevents dust from entering the interior of the earphone body 1 as much as possible, thereby reducing the impact of dust on the earphone body 1.

[0032] The working principle of the utility model is: first, the user first inserts the earplug connecting tube 2 into the ear, and then the user turns on the air pump 4 and the electric push rod 7 by pressing the multi-function button 19, and uses the power provided by the air pump 4 to fill gas into the airbag 3, so that the airbag 3 expands and contacts the user's ear, thereby sealing the user's ear, and at the same time uses the power provided by the electric push rod 7 to cooperate with the connecting spring 9 to drive the two expansion plates 8 to move toward the side away from the earplug connecting tube 2, so that the expansion plates 8 drive the rubber sleeve 6 to expand toward the side away from the earplug connecting tube 2, and then the outer surface of the rubber sleeve 6 contacts the user's ear, so that the Bluetooth headset performs double sealing and noise reduction on the user's ear, thereby ensuring the good noise reduction effect of the device, and at the same time, the user can adjust the size of the Bluetooth headset sound insulation structure according to their own needs, so that the device can be suitable for people with different sizes of ear holes, thereby increasing the practicality of the device.
