[0024] The above and other technical features and advantages of the present invention are described in more detail below in conjunction with the accompanying drawings.

[0025] This embodiment provides a technical solution: a Bluetooth headset, such as Figure 1-2 As shown, it includes an earphone housing 1 and a self-locking anti-fall protection component 2.

[0026] like Figure 1-2 and Figure 4As shown, the self-locking anti-fall protection component 2 is installed on the outside of the earphone shell 1 by bonding. The self-locking anti-fall protection component 2 is used to perform anti-fall self-locking protection on the Bluetooth earphone and the earphone shell 1. The self-locking anti-fall protection component 2 includes an anti-fall airbag 201 and a connecting rod 202 bonded to the outside of the earphone shell 1. The connecting rod 202 is fixedly installed on the anti-fall airbag 201. A lock hole 203 is opened on the connecting rod 202. A connecting cylinder 204, a piston cylinder 205 and an air outlet cylinder 206 are fixedly installed in the anti-fall airbag 201. The connecting rod 202 is inserted into the connecting cylinder 204. The piston cylinder 205 and the air outlet cylinder 206 are fixedly connected to the connecting cylinder 204. The air outlet cylinder 206 is connected to the connecting cylinder 204 through a connecting hole 207. The pressure inside the connecting cylinder 204 and the air outlet cylinder 206 is the same. The anti-fall airbag 20 1 is provided with an air outlet 208, the air outlet 208 is communicated with the air outlet cylinder 206, and the air outlet 208 is communicated with the air outside the self-locking anti-fall protection component 2, which can ensure that the pressure inside the air outlet cylinder 206 is the same as the external atmospheric pressure through the air outlet 208, and the side wall of the connecting cylinder 204 is movably penetrated with a locking rod 209, and the outer side wall of the locking rod 209 is fixedly equipped with a rubber sealing ring 210, the rubber sealing ring 210 is slidably connected with the inner side wall of the piston cylinder 205, and there is a gap between the locking rod 209 and the side wall of the connecting cylinder 204, which can ensure that a section of the piston cylinder 205 between the rubber sealing ring 210 and the connecting cylinder 204 is communicated with the connecting cylinder 204, and ensure that the pressure inside the section of the piston cylinder 205 between the rubber sealing ring 210 and the connecting cylinder 204 is the same as the pressure inside the connecting cylinder 204.

[0027] The inner wall of the anti-fall airbag 201 wraps the earphone shell 1. When the earphone shell 1 falls, the earphone shell 1 and the anti-fall airbag 201 fall together. Due to gravity, the outer wall of the anti-fall airbag 201 hits the ground, and the ground exerts a reverse impact force on the outer wall of the anti-fall airbag 201. The impact force exerted on the outer wall of the anti-fall airbag 201 is transmitted to the inner wall of the anti-fall airbag 201 through the air inside the anti-fall airbag 201. The gas inside the anti-fall airbag 201 can buffer the impact force exerted by the outer wall of the anti-fall airbag 201 on the inner wall of the anti-fall airbag 201, and the impact force exerted on the inner wall of the anti-fall airbag 201 is substantially reduced. The smaller impact force exerted on the inner wall of the anti-fall airbag 201 is transmitted to the earphone shell 1, which can prevent the earphone shell 1 from being directly impacted by the ground, and can better protect the earphone shell 1.

[0028] Before the anti-fall airbag 201 is impacted, the pressure inside the anti-fall airbag 201 is the same as the atmospheric pressure outside the anti-fall airbag 201. When the anti-fall airbag 201 hits the ground, the anti-fall airbag 201 is squeezed, and the volume inside the anti-fall airbag 201 is reduced, while the weight of the air inside the anti-fall airbag 201 remains unchanged, resulting in an increase in the pressure inside the anti-fall airbag 201. A through hole is provided on the side wall of the piston cylinder 205, and the side of the locking rod 209 facing away from the connecting rod 202 is connected to the air inside the anti-fall airbag 201 through the through hole. The pressure on the end of the locking rod 209 away from the rubber sealing ring 210 is the atmospheric pressure transmitted through the air outlet 208, the connecting hole 207, the air outlet tube 206 and the connecting tube 204. The pressure on the end of the locking rod 209 away from the rubber sealing ring 210 is less than the atmospheric pressure on the side wall. The pressure at one end of the through hole increases, and the pressure inside the anti-fall airbag 201 increases, which will squeeze the locking rod 209 through the through hole. The locking rod 209 drives the rubber sealing ring 210 to slide in the piston cylinder 205, and the end of the locking rod 209 away from the rubber sealing ring 210 is inserted into the locking hole 203 through the connecting tube 204. The locking hole 203 is fixed by the locking rod 209. The locking hole 203 can fix the connecting rod 202, and the connecting rod 202 fixes the upper half of the anti-fall airbag 201. The locking rod 209 fixes the lower half of the anti-fall airbag 201 and the upper half of the ear of the anti-fall airbag 201 through the connecting tube 204 and the connecting rod 202 to prevent the upper and lower halves of the anti-fall airbag 201 from separating. The anti-fall airbag 201 can fix the earphone shell 1 to prevent the earphone shell 1 from opening at the moment of being hit.

[0029] The anti-fall airbag 201 will rebound after being stabilized. The volume of the anti-fall airbag 201 will increase after rebounding, and the internal pressure will decrease. The external atmospheric pressure will apply squeezing force to the end of the locking rod 209 away from the rubber sealing ring 210 through the air outlet 208, the air outlet tube 206, the connecting hole 207 and the connecting tube 204. The locking rod 209 drives the rubber sealing ring 210 to slide in the piston cylinder 205 in the direction away from the locking hole 203, and the locking rod 209 is separated from the locking hole 203. Due to the impact, squeezing and rebound of the anti-fall airbag 201, the locking rod 209 can make a piston movement in the piston cylinder 205.

[0030] like Figure 1-4As shown, a magnet 1 3 is fixedly mounted on the self-locking anti-fall protection component 2, a magnet 2 4 is fixedly mounted inside the self-locking anti-fall protection component 2, the magnet 2 4 is movably connected to the magnet 1 3, an earphone slot 5 is opened in the earphone housing 1, a Bluetooth earphone body 6 is clamped in the earphone slot 5, the magnet 1 3 is fixedly mounted on the bottom surface of the connecting rod 202, the magnet 2 4 is fixedly mounted on the bottom surface of the connecting tube 204, the magnet 1 3 and the magnet 2 4 are magnetically attracted to each other, the magnet 1 3 and the magnet 2 4 are connected, driving the connecting rod 202 and the connecting tube 204 to be connected, and the connecting rod 202 and the connecting tube 204 are connected. The connection between 04 can drive the connection between the lower and upper parts of the anti-fall airbag 201, which can conveniently fix the earphone shell 1. At the same time, the earphone shell 1 can be conveniently and quickly opened to facilitate taking out the Bluetooth earphone body 6 inside the earphone slot 5. A threading hole 7 is provided on the self-locking anti-fall protection component 2, and a charging hole 8 is provided on the side wall of the earphone shell 1. The charging hole 8 is connected to the threading hole 7. When the Bluetooth earphone body 6 needs to be charged, the charging cable is inserted into the charging hole 8 through the threading hole 7, and the charging cable can charge the Bluetooth earphone body 6 in the earphone slot 5 through the earphone shell 1.

[0031] The above is only a preferred embodiment of the utility model, which is only illustrative and not restrictive. Those skilled in the art understand that many changes, modifications, and even equivalences can be made within the spirit and scope defined by the claims of the utility model, but they will all fall within the scope of protection of the utility model.
