[0040] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with embodiments and drawings. The exemplary embodiments of the present invention and their description are only used to explain the present invention and are not intended to limit the present invention.

[0041] Example:

[0042] like Figures 1 to 6 As shown, this embodiment relates to an anti-fall Bluetooth headset, comprising an earphone body 5, an earphone terminal 3 is provided on the earphone body 5, a sound outlet 2 is fixed on the earphone terminal 3, an earplug 1 is sleeved on the sound outlet 2, and an anti-fall power supply module 6 is embedded on the side of the earphone body 5 away from the earphone terminal 3;

[0043] A buffer inner layer component 4 is provided on the earphone body 5 , one end of the buffer inner layer component 4 partially protrudes from the top of the earphone body 5 , and the other end of the buffer inner layer component 4 extends into the earphone body 5 and fits against the inner wall of the earphone body 5 .

[0044] At present, during the use of Bluetooth headsets, the Bluetooth headsets are usually dropped. When the Bluetooth headsets are dropped, the headset body 5 is subjected to external impact, which will cause the internal structure to be damaged by vibration and the outer surface to be damaged by impact. The damage to the outer surface can be dealt with by materials with higher strength, but the internal structure of the headset body 5 will still be damaged by the shock impact. At the same time, the battery cells of the headset battery 69 will also be at risk of being damaged by the shock impact.

[0045] In this embodiment, through the setting of the earphone head 3 on the earphone main body 5, a connection position is effectively provided for the sound outlet nozzle 2, thereby reducing the risk of damage to the sound outlet nozzle 2. If the sound outlet nozzle 2 is damaged, the maintenance difficulty of the sound outlet nozzle 2 can also be reduced during maintenance. The earplug 1 is used to adapt to the user's use and protect the sound outlet nozzle 2;

[0046] The waterproof power supply module is used to protect the power supply safety of the earphone main body 5. The buffer inner layer assembly 4 is inside the earphone main body 5, so that the shock damage to the structure inside the earphone main body 5 can be reduced through the buffering effect. Part of the buffer inner layer assembly 4 protrudes from the earphone main body 5, so that the shock impact will not cause secondary damage to the internal structure of the earphone main body 5 during the absorption process, and the actual state of the buffer inner layer assembly 4 can also be observed through the protruding part, and maintenance can be carried out in time when the buffer inner layer assembly 4 fails.

[0047] Furthermore, the sound outlet nozzle 2 includes a straight section main body 23. One end of the straight section main body 23 is fixed with a coupling end 24, and the coupling end 24 is connected to the earphone head 3. The other end of the straight section main body 23 is fixed with a thickening section 22, and a sound outlet 21 is provided on the thickening section 22;

[0048] The earplug 1 is sleeved on the thickening section 22.

[0049] In this embodiment, the straight section main body 23 of the sound outlet nozzle 2 is used to transmit sound waves, the coupling end 24 is used to connect with the earphone head 3, the thickening section 22 is used to ensure the sound quality stability at the position of the sound outlet 21, and the earplug 1 is sleeved on the thickening section 22, so that the thickening section 22 can be effectively protected.

[0050] Furthermore, a buffer echo mechanism 25 is provided in the straight section main body 23. A stepped end face 26 is provided on one side of the buffer echo mechanism 25 close to the coupling end 24. The buffer echo mechanism 25 and the stepped end face 26 are both fixed to the straight section main body 23.

[0051] In this embodiment, the buffer echo mechanism 25 in the straight section main body 23 can buffer the sound outlet nozzle 2 on the basis of ensuring the sound wave transmission quality, thereby avoiding damage to the sound outlet nozzle 2 when it is impacted. The stepped end face 26 plays a limiting role and can limit the position of the buffer echo mechanism 25, so that the buffer echo mechanism 25 plays the correct role.

[0052] Furthermore, the buffer echo mechanism 25 includes a plurality of annular bodies 251, and a plurality of arc plates 252 are fixed on the annular bodies 251. The arc plates 252 are all bent and extend towards the sound outlet 21;

[0053] The thickening section 22 includes a first expansion section 221 and a second expansion section 222. Both the first expansion section 221 and the second expansion section 222 gradually thicken from the side close to the joint end 24 to the side close to the sound outlet 21. The thickness increase of the second expansion section 222 per unit length is greater than that of the first expansion section 221.

[0054] In this embodiment, the annular body 251 is used to carry the arc plate 252. The annular body 251 can effectively ensure the stability during the sound wave propagation process, and can make the sound wave propagate directionally under the action of the arc plate 252, and can improve the sound quality at the position of the sound outlet 21 through the action of sound wave reflection. The first expansion section 221 and the second expansion section 222 of the thickening section 22 gradually thicken, so as to ensure the stability of the sound at the sound outlet 21 on the basis of providing a sleeving and supporting position for the earplug 1.

[0055] Furthermore, the buffer inner layer assembly 4 includes an inner covering airbag 45, and the inner covering airbag 45 fits the inner wall of the earphone main body 5;

[0056] An outer airbag 41 is provided at the top of the inner covering airbag 45, and the outer airbag 41 protrudes outside the earphone main body 5;

[0057] The outer airbag 41 and the inner covering airbag 45 are communicated through a connecting pipe 43.

[0058] In this embodiment, the inner covering airbag 45 fits the inner wall of the earphone main body 5. Therefore, when the earphone main body 5 is impacted by the outside world, the inner covering airbag 45 can effectively provide a shock absorption effect for the internal structure of the earphone main body 5, thereby preventing the internal part of the earphone main body 5 from being damaged. The outer airbag 41 communicated with the inner covering airbag 45 can effectively form an impact resistance outside, thereby providing a buffering ability for the earphone main body 5 within a local range. On this basis, since the outer airbag 41 and the inner covering airbag 45 are communicated, the state of the outer airbag 41 can effectively reflect the state of the inner covering airbag 45. When the outer airbag 41 deflates, the inner covering airbag 45 will also be in a deflated state, and at this time, it cannot form a shock absorption effect on the earphone main body 5 and needs to be maintained.

[0059] In this embodiment, a one-way valve 42 is provided on the outer airbag 41, so that when the outer airbag 41 and / or the inner covering airbag 45 is in a deflated state, gas can be injected into the outer airbag 41 through the one-way valve 42 for replenishment, so as to fill the inner covering airbag 45 and achieve the purpose of making the inner covering airbag 45 form a shock absorption effect.

[0060] Further, a stabilizing plate 44 is provided on one side of the inner covering airbag 45 close to the inside of the earphone main body 5, and the stabilizing plate 44 is fixed to the earphone main body 5;

[0061] A contact layer 46 is fixed on one side of the stabilizing plate 44 close to the inside of the earphone main body 5, and the contact layer 46 is filled with a stabilizing filler 48.

[0062] In this embodiment, the inner covering airbag 45 is limited by the stabilizing plate 44 inside the earphone main body 5, so that when a shock absorption effect is formed in the inner covering airbag 45, it can be restricted, and the inner covering airbag 45 is prevented from squeezing the internal structure of the earphone main body 5. The contact layer 46 on the stabilizing plate 44 is made of a flexible material, so that it can protect other structures in contact. The stabilizing filler 48 is made of a filler material with the ability of deformation recovery, so that when the contact layer 46 deforms during the protection of other structures, it can also return to the original shape through the stabilizing filler 48.

[0063] The material used for the stabilizing filler 48 is a material that can be purchased on a large scale by existing technologies, so as to ensure the mass production of this embodiment.

[0064] Further, the anti-drop battery 69 module includes an anti-drop housing 612. An embedding end 61 that can be embedded in the earphone main body 5 is fixed on the upper half of the anti-drop housing 612, and a battery 69 is fixed on the lower half of the anti-drop housing 612. The top of the battery 69 is fixed to the embedding end 61.

[0065] In this embodiment, the anti-drop housing 612 serves as an outer protection. The embedding end 61 is electrically connected to the inside of the earphone main body 5 by being embedded in the earphone main body 5, and this embodiment is powered by the battery 69.

[0066] Further, a power contact 66 is provided inside the embedding end 61, and a suspension stabilizing frame is provided on the power contact 66 for suspending and carrying the power contact 66;

[0067] The power contact 66 is electrically connected to the battery 69;

[0068] The anti-drop housing 612 is filled with an anti-drop filler 611.

[0069] Since the power supply contact 66 is prone to problems such as breakpoints when subjected to shock impacts, in this embodiment, by embedding a suspension stabilizer in the end head 61, when the earphone body 5 is subjected to shock impacts, the suspension stabilizer can accommodate the vibration amplitude of the power supply contact 66, thereby avoiding the breakage of the power supply contact 66. The anti-drop filling 611 is filled with an elastic material to enhance the impact resistance and buffering ability of the anti-drop housing 612 when subjected to external forces.

[0070] Further, the suspension stabilizer includes a suspended frame 67. The suspended frame 67 is sleeved outside the power supply contact 66. A first bearing plate 68 is fixed at the bottom of the suspended frame 67, and a second bearing plate 610 is fixed at the top thereof. A first spring 62 and a second spring 63 are fixed at the top of the second bearing plate 610. A first elastic cord 64 and a second elastic cord 65 penetrate through the lower part of the second bearing plate 610. The first spring 62, the second spring 63, the first elastic cord 64 and the second elastic cord 65 are all fixed to the inner top surface of the embedded end head 61.

[0071] The first spring 62 and the second spring 63 are symmetrically distributed with respect to the center line of the second bearing plate 610, and the first elastic cord 64 and the second elastic cord 65 are symmetrically distributed with respect to the center of gravity of the second bearing plate 610.

[0072] In this embodiment, the suspended frame 67 is used to carry the first bearing plate 68 and the second bearing plate 610. The second bearing plate 610 is suspended by the combined action of the first elastic cord 64, the second elastic cord 65, the first spring 62 and the second spring 63, and the second bearing plate 610 bears the overall weight on the suspended frame 67. The first elastic cord 64, the second elastic cord 65, the first spring 62 and the second spring 63 utilize their own elastic acting forces to effectively buffer when the power supply contact 66 vibrates while playing a supporting role, thereby ensuring the connection safety of the power supply contact 66.

[0073] The first elastic cord 64 and the second elastic cord 65 pass through from below the second bearing plate 610, so as to provide bearing capacity for the second bearing plate 610 by the way of holding the second bearing plate 610. The first spring 62 and the second spring 63 directly act on the upper surface of the second bearing plate 610, so that the first spring 62 and the second spring 63 can form a direct lifting bearing for the second bearing plate 610. In this embodiment, the elastic force provided by the first elastic cord 64 and the second elastic cord 65 for the second bearing plate 610 can avoid the sinking of the second bearing plate 610 without affecting its upward vibration amplitude, thus more conforming to the scenario required when the power supply contact 66 is impacted, and making the force distribution of the second bearing plate 610 more reasonable.

[0074] Further, the suspended frame 67 includes a frame body 671, and both the first bearing plate 68 and the second bearing plate 610 are fixed to the frame body 671;

[0075] An upper horizontal synchronous connecting rod 673 and a lower horizontal synchronous connecting rod 679 are provided in the frame body 671. The upper horizontal synchronous connecting rod 673 and the lower horizontal synchronous connecting rod 679 are parallel to each other. A vertical synchronous connecting rod 675 is provided between the upper horizontal synchronous connecting rod 673 and the lower horizontal synchronous connecting rod 679. Both ends of the vertical synchronous connecting rod 675 are fixed to the upper horizontal synchronous connecting rod 673 and the lower horizontal synchronous connecting rod 679 respectively;

[0076] Edge mounting rings 674251 are fixed to both ends of the upper horizontal synchronous connecting rod 673 and both ends of the lower horizontal synchronous connecting rod 679. A plurality of intermediate mounting rings 677251 are provided between the edge mounting rings 674251;

[0077] Longitudinal springs 672 are fixed between the upper horizontal synchronous connecting rod 673 and the second bearing plate 610, and between the lower water synchronous connecting rod and the first bearing plate 68. First lateral springs 676 and second lateral springs 678 are provided on the edge mounting rings 674251. One end of the first lateral spring 676 is fixed to the edge mounting ring 674251, and the other end is fixed to the frame body 671. One end of the second lateral spring 678 is fixed to the edge mounting ring 674251, and the other end is fixed to the frame body 671;

[0078] The included angle between the axis of the first lateral spring 676 and the axis of the second lateral spring 678 is greater than or equal to 60°.

[0079] In this embodiment, the frame body 671 is used to accommodate the upper horizontal synchronization connecting rod 673 and the lower horizontal synchronization connecting rod 679, so as to effectively carry the edge carrying ring body 674251 and the middle carrying ring body 677251. Both the edge carrying ring body 674251 and the middle carrying ring body 677251 can effectively carry the power contact 66. Under the action of the upper horizontal synchronization connecting rod 673 and the lower horizontal synchronization connecting rod 679, the relative positions of the power contacts 66 can be ensured to be unified, thereby preventing the power contacts 66 from deforming. The vertical synchronization connecting rod 675 can make the edge carrying ring body 674251 and the middle carrying ring body 677251 on the upper horizontal synchronization connecting rod 673 and the lower horizontal synchronization connecting rod 679 move synchronously, so that the power contacts 66 change synchronously as a whole, avoiding local deformation of the power contacts 66.

[0080] The longitudinal spring 672 can provide longitudinal buffering and shock absorption capabilities for the upper horizontal synchronization connecting rod 673 and the lower water synchronization connecting rod. The first lateral spring 676 and the second lateral spring 678 can provide lateral buffering and shock absorption capabilities for the edge carrying ring body 674251. Therefore, when subjected to external impacts, the longitudinal spring 672, the first lateral spring 676 and the second lateral spring 678 can effectively reduce the external forces in various directions, thereby playing a role in protecting the power contact 66.

[0081] The included angle between the axis of the first lateral spring 676 and the axis of the second lateral spring 678 is greater than or equal to 60°, so that the first lateral spring 676 and the second lateral spring 678 can adapt to a wider range of shock absorption effects, improve the adaptability of this embodiment, and enhance the anti-drop performance of this embodiment.
