DETAILED DESCRIPTION

[0028] In order to make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments.

A circular installation cavity is opened, and an earphone cover 5 is arranged at the opening of the installation cavity, and a first clamping ring 6 is arranged on the side of the earphone cover 5 opposite to the installation cavity, and the first clamping ring 6 is slidably inserted in the installation cavity, and a truncated cone-shaped installation box 7 is arranged in the installation cavity, and the installation box 7 can be clamped in the installation cavity under the action of the first clamping ring 6, and the opening of the installation box 7 faces the direction of the earphone sound insulation cover 4, and a clamping assembly 8 is arranged at the opening of the installation box 7, and an earphone speaker 9 is arranged in the installation box 7, and the membrane of the earphone speaker 9 The sheet is opposite to the pressing assembly 8, and the end of the earphone speaker 9 away from the sealing cover is sleeved with a support ring 10, and a plurality of support rods 11 are hinged on the outer side of the support ring 10, and the plurality of support rods 11 are evenly distributed in an annular shape, and the end of the support rod 11 away from the support ring 10 is slidably sleeved with a support tube 12, and the end of the support tube 12 away from the support ring 10 is hinged to the inner wall of the installation box 7, and a shock-absorbing spring 13 is fixedly connected between the end of the support rod 11 located in the support tube 12 and the inner wall of the support tube 12, and a square battery 14 is arranged on the side of the installation box 7 away from the pressing assembly 8, and limit strips 15 are arranged around the battery 14, and the limit strips 15 are fixedly connected to the earphone cover 5, and the middle part of the earphone fixing frame 1 is sleeved with a leather protective cover 23, and the inner lining of the protective cover 23 is also a memory sponge 21, and a Bluetooth circuit board (not shown in the figure) is installed in the gap between the periphery of the earphone speaker 9 and the installation box 7;

[0030] The clamping assembly 8 includes a second clamping ring 81, a connecting ring 82 is fixedly connected to the side of the second clamping ring 81 close to the earphone speaker 9, the outer side of the connecting ring 82 is threadedly connected to the inner wall of the side of the installation box 7, an annular groove is provided on the inner side of the second clamping ring 81, and an annular plate 83 is movably installed in the groove, the outer diameter of the annular plate 83 is larger than the inner diameter of the second clamping ring 81, and the inner edge of the annular plate 83 protrudes in the direction close to the earphone speaker 9, and the protruding position of the inner edge of the annular plate 83 is fixedly connected to the annular pressure plate 8 4, and the pressing plate 84 is fitted with the side of the second clamping ring 81 close to the earphone speaker 9, the inner diameter of the pressing plate 84 is the same as the inner diameter of the annular plate 83, the outer diameter of the pressing plate 84 is larger than the inner diameter of the second clamping ring 81, the side of the pressing plate 84 close to the earphone speaker 9 is provided with an annular groove 85 matching the size of the earphone speaker 9, and the side of the earphone speaker 9 close to the earphone soundproof cover 4 is clamped in the annular groove 85, and an annular buffer pad 17 is fixedly connected in the annular groove 85, and the buffer pad 17 is padded between the annular groove 85 and the earphone speaker 9;

[0031] When installing the earphone speaker 9, the earphone speaker 9 is first installed according to Figure 2 The first clamping ring 81 is inserted into the support ring 10, and then the connecting ring 82 on the second clamping ring 81 is screwed into the inner side of the opening of the installation box 7. As the connecting ring 82 is gradually screwed into the installation box 7, the pressing plate 84 gradually contacts the earphone speaker 9. Then, a finger is inserted into the inner side of the installation box 7 through the hole in the middle of the pressing plate 84 to fine-tune the position of the earphone speaker 9, so that the earphone speaker 9 can be snapped into the annular groove 85 on the pressing plate 84. Then, the second clamping ring 81 is continued to be screwed. At this time, as the pressing plate 84 continuously squeezes the earphone speaker 9, the support ring 10 is also pressed under the pressure of the earphone speaker 9. The plurality of support rods 11 are squeezed, so that the shock absorbing spring 13 in the support tube 12 is gradually compressed. As the second clamping ring 81 is continuously screwed, when the second clamping ring 81 contacts the edge of the installation box 7, the screwing of the second clamping ring 81 is stopped. At this time, the earphone speaker 9 can be fixed under the cooperation of the clamping assembly and the plurality of support rods 11 and the support ring 10, and the shock absorbing spring 13 is also in a semi-compressed state. When the second clamping ring 81 is tightened, the earphone speaker 9 together with the Bluetooth circuit board is separated from the battery 14 and separately isolated in the installation box 7, thereby reducing the influence of the battery 14 on the earphone speaker 9;

[0032] After the earphone speaker 9 is installed in the installation box 7, the installation box 7 is placed in the installation cavity of the earphone fixing seat 3, and then the earphone cover 5 is closed after the battery 14 is connected to the Bluetooth circuit board, so that the installation box 7 is pressed and fixed by the first clamping ring 6 on the earphone cover 5;

[0033] When the Bluetooth headset is in use, when the earphone speaker 9 generates vibration, the shock absorbing spring 13 in the support tube 12 and the buffer pad 17 in the annular groove 85 can absorb the vibration generated by the earphone speaker 9, thereby reducing the influence of the vibration on the overall sound effect of the Bluetooth headset;

[0034] In addition, during the use of the Bluetooth headset, when the Bluetooth headset accidentally falls to the ground, as the headset fixing seat 3 contacts the ground, the headset fixing seat 3 can stop moving, and the headset speaker 9 can continue to move downward under the action of inertia. During this process, the headset speaker 9 can drive the pressure plate 84 and the support ring 10 to move downward together through the thrust on the inner edge of the annular groove 85 and the thrust of the headset speaker 9 on the support ring 10. As the support ring 10 moves downward, the support rod 11 located in the movement direction of the support ring 10 can further compress the shock-absorbing spring 13 in the corresponding support tube 12, thereby converting the impact force on the headset speaker 9 into the elastic potential energy of the shock-absorbing spring 13, and then playing a buffering and protective role on the headset speaker 9, avoiding the loosening or damage of the headset speaker 9 under the existing fixed connection method, and when the Bluetooth headset is completely stable, the headset speaker 9 can return to its original position under the action of multiple support rods 11 and multiple shock-absorbing springs 13.

[0035] like Figure 2 , Figure 5 and Figure 6 As shown, a plurality of bow-shaped spring pieces 16 are fixedly connected to the edge of the pressure plate 84, and the plurality of bow-shaped spring pieces 16 are evenly distributed in an annular shape. In the initial state, the plurality of bow-shaped spring pieces 16 can fit with the inner side of the connecting ring 82, and the second clamping ring 81 and the pressure plate 84 can both remain coaxial with the mounting box 7 and the support ring 10 under the limiting effect of the plurality of bow-shaped spring pieces 16.

[0036] By arranging the bow-shaped spring pieces 16 at the edge of the pressure plate 84, on the one hand, when the second clamping ring 81 is connected to the installation box 7 through the connecting ring 82, the pressure plate 84 installed on the second clamping ring 81 can maintain a centered state under the limiting action of multiple bow-shaped spring pieces 16, so that the headphone speaker 9 can be more conveniently installed in the annular groove 85 of the pressure plate 84. In addition, when the headphone speaker 9 is offset due to external vibrations, the multiple bow-shaped spring pieces 16 can cooperate with the multiple shock-absorbing springs 13 to reset the headphone speaker 9 as soon as possible, while also improving the buffering effect when the headphone speaker 9 is hit.

[0037] like Figure 2 As shown, a circular installation groove is provided on one side of the installation cavity opposite to the second clamping ring 81, a sponge filter 18 is provided in the installation groove, and the diameter of the sponge filter 18 is larger than the inner diameter of the second clamping ring 81;

[0038] By providing the sponge filter 18 , during the use of the earphone, the sponge filter 18 can protect the opening of the installation box 7 , thereby preventing water vapor and dust from entering the installation box 7 and affecting the earphone speaker 9 .

[0039] like Figure 2 and Figure 7 As shown, a sponge pad 19 is fixedly connected to one side of the battery 14 close to the installation box 7, and the sponge pad 19 is tightly attached to the installation box 7;

[0040] By providing the sponge pad 19 , when the earphone cover 5 and the installation box 7 are tightly attached together, the sponge pad 19 can press and fix the battery 14 .

[0041] like Figure 2 and Figure 7 As shown, a shock-absorbing rubber ring 20 is fixedly connected to one side of the first clamping ring 6 located in the installation cavity, and the shock-absorbing rubber ring 20 is tightly fitted with the installation box 7;

[0042] By arranging the shock-absorbing rubber ring 20 on the first clamping ring 6 , when the first clamping ring 6 clamps and fixes the installation box 7 , the shock-absorbing rubber ring 20 can be deformed due to extrusion, thereby ensuring that the first clamping ring 6 and the installation box 7 are tightly fitted.

[0043] like Figure 2 As shown, the earphone soundproof cover 4 is lined with a memory foam 21, and a stainless steel metal hose 22 is wrapped in the memory foam 21, and the surface of the earphone soundproof cover 4 is made of soft leather;

[0044] By adding a stainless steel metal hose 22 to the memory sponge 21 in the earphone sound insulation cover 4, when the user wears the Bluetooth headset, the user can press the earphone cover 5 with his hand, so that the earphone sound insulation cover 4 can keep in contact with the skin around the user's ear, and as the memory sponge 21 is squeezed, the stainless steel metal hose 22 wrapped in the memory sponge 21 can also bend along with the skin around the user's ear, and then the bent stainless steel metal hose 22 can maintain the same shape as the area around the user's ear and be supported inside the memory sponge 21, so that the memory sponge 21 can better fit the user's ear, thereby enhancing the isolation effect of the earphone sound insulation cover 4 against external noise.
