[0022] A method for using a Bluetooth headset comprises the following steps:

[0023] S1: differential pressure power generation:

[0024] When the Bluetooth headset is worn and used, when the speaker plays sound, the speaker drives the synchronous vibration ring to resonate, and the synchronous vibration ring drives the output end of the pressure difference power generation column to expand and contract, and then drives the output ends of multiple pressure difference power generation columns to perform frequency compression to generate a pressure difference, and transmit the generated electrical energy to the backup power supply to realize pressure difference power generation;

[0025] S2: Photovoltaic power generation:

[0026] When the Bluetooth headset is worn and used, the two photovoltaic panels are at the farthest distance. The two photovoltaic panels receive solar energy to generate electricity and transmit the generated electricity to the backup power supply, thus realizing photovoltaic power generation for the Bluetooth headset.

[0027] S3: Thermal power generation:

[0028] The Bluetooth headset generates a large amount of waste heat when charging, a small amount of waste heat when working, and waste heat generated by the photovoltaic panel when absorbing sunlight energy. The above waste heat dissipates between the first and second earphone shells, and then the above waste heat overflows between the first and second earphone shells. The reflective plate reflects the three types of waste heat, so that the heat radiation is concentrated towards the micro-thermal power generation module. The micro-thermal power generation module absorbs the heat radiation between the first and second earphone shells and generates electricity using the thermoelectric effect, ultimately achieving thermal energy power generation.

[0029] S4: Voltage stabilization and power storage:

[0030] The electric energy generated in the process of pressure difference power generation, photovoltaic power generation and thermal power generation is stored in the backup power supply through the boost and voltage stabilization module to achieve voltage stabilization and power storage;

[0031] S5: Switch power supply:

[0032] When the display shows that the main power supply is fully charged, the main power supply supplies power to the circuit board;

[0033] When the display screen shows that the power in the main power supply is exhausted, the switching component is operated accordingly to disconnect the electrical connection between the main power supply and the circuit main board, and the backup power supply and the circuit main board are electrically connected, so that the backup power supply supplies power to the circuit main board.

[0034] Compared with the prior art, the present invention has the following beneficial effects:

[0035] 1. The present invention is based on energy recovery for backup power generation. The above energy recovery includes heat recovery, kinetic energy recovery and light energy recovery. Among them, heat recovery includes waste heat from earphone operation, waste heat from earphone charging and waste heat from light energy recovery. The thermal radiation power generation module uses the above three types of waste heat to generate electricity, the photovoltaic power generation module uses light energy to generate electricity, and the kinetic energy power generation module uses vibration to generate electricity. Under the premise of ensuring green and environmental protection, the backup power supply of the Bluetooth headset is supplemented. When there is no other power supply to supplement the power in the surrounding area, the Bluetooth headset is guaranteed to work normally by switching to the backup power supply. The present invention generates electricity based on the principle of energy recovery. While effectively improving the battery life of the Bluetooth headset, it can also achieve energy-saving and environmental protection effects.

[0036] 2. The reflective plate of the present invention is used to reflect thermal radiation so that the heat is concentrated at the micro-thermal power generation module, further improving the power generation efficiency of the micro-thermal power generation module. The micro-thermal power generation module is used to collect the heat radiation generated when the photovoltaic panel absorbs solar energy, the large amount of waste heat generated when the Bluetooth headset is charging in the Bluetooth headset cabin, and the trace waste heat generated when the Bluetooth headset is in a working state. The reflective plate reflects the three kinds of waste heat, so that the heat radiation is absorbed by the micro-thermal power generation module between the earphone shell one and the earphone shell two, and generates electricity by using the thermoelectric effect. By collecting the heat generated during the use of the Bluetooth headset to generate electricity, while ensuring green and environmental protection, the power supply of the Bluetooth headset is effectively supplemented, thereby effectively extending the battery life of the Bluetooth headset.

[0037] 3. When the Bluetooth headset is worn and used, the photovoltaic panel receives solar energy to generate electricity and transmits the generated electricity to the backup power supply, effectively extending the battery life of the Bluetooth headset.

[0038] 4. During the wearing and use of the Bluetooth headset of the present invention, when the speaker plays sound, the speaker vibrates and drives the synchronous vibration ring to resonate, and the synchronous vibration ring drives the output end of the pressure difference power generation column to telescope and move, and then drives the output ends of multiple pressure difference power generation columns to perform frequency compression to generate a pressure difference, and transmit the generated electrical energy to the backup power supply to realize pressure difference power generation.

[0039] 5. The synchronous vibration ring in the present invention is used to vibrate synchronously with the speaker to achieve the effect of collecting vibration force. At the same time, the synchronous vibration ring vibrates synchronously with the speaker to offset the abnormal vibration generated by the speaker when the user is in a stroll or walking state, thereby effectively improving the sound quality of the Bluetooth headset.

[0040] 6. The present invention realizes the switching between the main power supply and the backup power supply through a switching component. When the display screen shows that the main power supply is fully charged, the main power supply supplies power to the circuit main board; when the display screen shows that the main power supply is exhausted, the switching component is operated accordingly to disconnect the electrical connection between the main power supply and the circuit main board, and electrically connect the backup power supply to the circuit main board, so that the backup power supply supplies power to the circuit main board, thereby realizing the switching between the main power supply and the backup power supply. The switching component in the present invention is easy to operate, ingeniously designed, and highly practical.

[0041] 7. The present invention can also improve the sound quality of Bluetooth headsets by covering the inner wall of the earphone shell with a layer of thermal insulation cotton. The thermal insulation cotton has two functions: first, the present invention is based on the fact that waste heat will be generated during the energy recovery process, and the waste heat will be directed into the user's ears. Therefore, the present invention uses thermal insulation cotton to isolate the radiation introduction of the above heat. At the same time, the thermal insulation cotton can effectively offset the abnormal vibration generated by the speaker, and cooperate with the synchronous vibration ring to achieve the synchronous vibration effect with the speaker, ultimately achieving the effect of doubly improving the sound quality of the Bluetooth headset, effectively improving the user experience.

[0042] 8. The opening of multiple air flow holes in the present invention is used to facilitate the exchange of air between earphone shell 1 and earphone shell 2 and the outside, accelerate the air circulation inside and outside, and avoid excessive heat accumulation between earphone shell 1 and earphone shell 2. At the same time, the opening of air flow holes facilitates the acceleration of heat radiation, thereby accelerating the power generation efficiency of thermal energy power generation.

[0043] 9. The U-shaped card holder of the present invention is used to accommodate the insertion of the card block. The card block is plugged into the U-shaped card holder to make the earphone shell one and the earphone shell two relative to each other and fixed. Through the engagement of multiple sets of card connection mechanisms, the earphone shell one and the earphone shell two are sealed and connected, effectively ensuring the sealing between the earphone shell one and the earphone shell two, and preventing foreign matter from entering between the earphone shell one and the earphone shell two.

[0061] The core innovation of the present invention will be described as follows:

[0062] The present invention improves the battery life of Bluetooth headsets by setting up a power generation mechanism. The power generation mechanism is provided in two groups, and the two groups of power generation mechanisms are arranged between two earphone shells 1 4 and earphone shell 2 5 to provide backup power for the circuit main board 23.

[0064] In the present invention, the earphone cabin 1 and the flip cover 2 are combined into a Bluetooth earphone cabin through a hinge shaft to store and replenish power for the Bluetooth earphone.

[0080] Example 2:

[0081] Compared with Example 1, the difference of Example 2 is that the inner wall of the earphone shell 1 4 is covered with a layer of heat insulating cotton 36. The heat insulating cotton 36 has two functions:

[0082] Firstly, the present invention is based on the fact that waste heat is generated during the energy recovery process and is directed into the user's ears. Therefore, the present invention uses the heat insulation cotton 36 to isolate the radiation introduction of the above heat, thereby improving the user experience.

[0083] Secondly, the heat-insulating cotton 36 can effectively offset the abnormal vibration generated by the speaker, and cooperate with the synchronous vibration ring 34 to offset the abnormal vibration generated by the speaker 30 by vibrating synchronously with the speaker 30, thereby further improving the sound quality of the Bluetooth headset.

[0084] Example 3:

[0085] This embodiment provides a method for using the Bluetooth headset described in Embodiment 1 or Embodiment 2, which includes the following steps:

[0086] S1: differential pressure power generation:

[0087] When the Bluetooth headset is worn and used, the speaker 30 plays sound, and the speaker 30 vibrates and drives the synchronous vibration ring 34 to resonate. The synchronous vibration ring 34 drives the output end of the pressure difference power generation column 33 to move telescopically, and then drives the output ends of multiple pressure difference power generation columns 33 to perform frequency compression to generate a pressure difference, and transmits the generated electrical energy to the backup power supply 24, realizing pressure difference power generation;

[0088] S2: Photovoltaic power generation:

[0089] When the Bluetooth headset is worn and used, the two photovoltaic panels 12 are at the farthest distance. The two photovoltaic panels 12 receive light to generate electricity and transmit the generated electricity to the backup power supply 24, thereby realizing photovoltaic power generation of the Bluetooth headset.

[0090] S3: Thermal power generation:

[0091] The Bluetooth headset generates a large amount of waste heat when charging, a small amount of waste heat when working, and waste heat generated by the photovoltaic panel 12 when absorbing sunlight energy. The above waste heat dissipates between the earphone shell 1 4 and the earphone shell 2 5, and then the above waste heat overflows between the earphone shell 1 4 and the earphone shell 2 5. The reflective plate 27 reflects the three types of waste heat, so that the heat radiation is concentrated to the micro-thermal power generation module 26. The micro-thermal power generation module 26 absorbs the heat radiation between the earphone shell 1 4 and the earphone shell 2 5 and generates electricity by using the thermoelectric effect, thereby ultimately achieving thermal energy power generation.

[0092] S4: Voltage stabilization and power storage:

[0093] The electric energy generated in the process of pressure difference power generation, photovoltaic power generation and thermal power generation is transformed by the boost and voltage stabilization module 35 and stored in the backup power supply 24 to achieve voltage stabilization and power storage;

[0094] S5: Switch power supply:

[0095] When the display screen 8 shows that the power in the main power supply 25 is fully charged, the main power supply 25 supplies power to the circuit main board 23;

[0096] When the display screen 8 shows that the power in the main power supply 25 is exhausted, the switching component is operated accordingly to disconnect the electrical connection between the main power supply 25 and the circuit main board 23, and the backup power supply 24 and the circuit main board 23 are electrically connected, so that the backup power supply 24 supplies power to the circuit main board 23.

[0097] In a specific embodiment, when the display screen 8 indicates that the main power supply 25 is fully charged, the V-shaped push block 21 is pressed, and one side of the V-shaped electrical contact 20 is abutted against an auxiliary electrical contact 19. The main power supply 25 is electrically connected to the main electrical contact 18, the V-shaped electrical contact 20, the auxiliary electrical contact 19, and the circuit board 23. At this time, the main power supply 25 supplies power to the circuit board 23.

[0098] When the display screen 8 indicates that the power in the main power supply 25 is about to be exhausted, the slider 17 can be toggled. The slider 17 moves in the slide groove 16, and the slide groove 16 pushes the other side of the V-shaped push block 21 to fit with the other auxiliary electrical contact block 19. At this time, the main electrical contact block 18, the V-shaped electrical contact piece 20, the auxiliary electrical contact block 19, the backup power supply 24 and the circuit board 23 are electrically connected, so that the backup power supply 24 supplies power to the circuit board 23, realizing power switching.
