DETAILED DESCRIPTION

[0019] To facilitate understanding of the present invention, a more comprehensive description of the present invention will be provided below with reference to the accompanying drawings. The drawings illustrate several embodiments of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and comprehensive understanding of the present invention.

[0020] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be an intermediate element. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains. The terms used herein in the specification of this invention are intended only to describe specific embodiments and are not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0022] A waterproof Bluetooth headset, such as Figure 1 and Figure 2As shown, it includes a shell 1 with an inner cavity 4, a sound tube 2 with a sound hole 5 arranged on the shell 1, the sound hole 5 is connected to the inner cavity 4, an earplug 3 is arranged on the sound tube 2, a sound receiving hole 13 is arranged at the lower part of the shell 1, and an electronic device module 6 and a waterproof mechanism are arranged at the inner cavity 4 of the shell 1; the waterproof mechanism includes a sliding frame 7 slidably connected to the shell 1, a speaker 8, a sealing block 9 and a sealing member 12 arranged on the sliding frame 7, and the waterproof mechanism also includes a driving component 14 for driving the sliding frame 7 to move, the driving component 14 drives the sliding frame 7 to move, and the sliding frame 7 drives the sealing block 9 and the sealing member 12 to move to the positions of the sound hole 5 and the sound receiving hole 13 respectively, thereby blocking the sound hole 5 and the sound receiving hole 13.

[0023] Among them, the shell 1 and the sound transmission tube 2 are both cylindrical in shape, and the inner cavity 4 of the shell 1 is also cylindrical in shape. The electronic device module 6 includes a mainboard responsible for signal processing and connection functions, a battery for providing working power, and a microphone for collecting external environmental sounds. The electronic device module 6 is a prior art, including but not limited to the above-mentioned electronic modules, and may also include other electronic modules such as noise reduction modules. The speaker 8 is used to play sound, and the sound played by the speaker 8 is transmitted to the human ear through the sound transmission hole 5 when people are talking and using the voice assistant function. The voice emitted by people enters the inner cavity 4 of the shell 1 through the sound receiving hole 13 and is received by the microphone;

[0024] It can be understood that people can operate the driving component 14, and the driving component 14 drives the sliding frame 7 to move downward, and the sliding frame 7 moves downward to drive the sealing block 9, the sealing member 12 and the speaker 8 to move downward. When the sealing member 12 moves downward to the extreme position, the sealing member 12 covers the sound receiving hole 13, blocking the sound receiving hole 13, and the sealing block 9 is also located at the sound transmission hole 5, blocking the sound transmission hole 5. Therefore, when the Bluetooth headset falls into water, water cannot enter the inner cavity 4 of the shell 1 through the sound transmission hole 5 and the sound transmission hole 5, thereby avoiding external The electronic components in the inner cavity 4 of the shell 1 are damaged. When people need to use the Bluetooth headset, they operate the operable driving component 14 to make the driving component 14 drive the sliding frame 7 to move upward. When the sliding frame 7 moves upward, the seal 12 no longer blocks the sound receiving hole 13, and the sealing block 9 no longer blocks the sound transmission hole 5. When the sliding frame 7 moves upward to the extreme position, the speaker 8 is opposite to the sound transmission hole 5, so that the sound played by the speaker 8 is transmitted to people's ears through the sound transmission hole 5, and the external environmental sound is received by the microphone in the electronic device module 6 through the sound receiving hole 13.

[0025] To sum up, by arranging the sealing member 12 and the sealing block 9 in the inner cavity 4 of the shell 1, the beauty of the Bluetooth headset can be increased, and the sealing member 12 and the sealing block 9 will not cause discomfort to people when using the Bluetooth headset. Furthermore, the sealing member 12 can block the sound receiving hole 13, thereby achieving a waterproof effect on the sound receiving hole 13. In addition, the sound transmission hole 5 and the sound receiving hole 13 can be blocked by simply operating the driving component 14, which can achieve an easy operation effect. In addition, by making the rubber pad 10 and the extrusion block 11 squeeze in close contact, water can be prevented from flowing from the gap between the sealing block 9 and the inner wall of the shell 1 to the electronic device module 6, thereby further achieving a waterproof effect.

[0026] like Figure 2 As shown, a circular arc-shaped rubber pad 10 is provided on the bottom surface of the sealing block 9, and a circular arc-shaped extrusion block 11 is provided at the inner cavity 4 of the shell 1. When the sealing block 9 blocks the sound hole 5, the rubber pad 10 fits tightly with the extrusion block 11.

[0027] It can be understood that when the sliding frame 7 moves downward, it drives the sealing block 9 to move downward, and the sealing block 9 drives the rubber pad 10 to move downward. The rubber pad 10 moves downward and contacts the extrusion block 11, so that the rubber pad 10 and the extrusion block 11 are in close contact by squeezing, which can prevent water from flowing from the gap between the sealing block 9 and the inner wall of the shell 1 to the electronic device module 6, thereby further achieving a waterproof effect.

[0028] like Figure 3 As shown, the sealing member 12 includes a sealing plate 121 fixedly connected to the sliding frame 7, and a protrusion 122 adapted to the shape of the sound hole 13 is arranged on the sealing plate 121. When the sealing member 12 moves to the position of the sound hole 13, the sealing plate 121 covers the upper part of the sound hole 13, and the protrusion 122 is located in the sound hole 13, thereby blocking the sound hole 13.

[0029] It can be understood that the sealing plate 121 covers the upper part of the sound receiving hole 13 and the protrusion 122 blocks the sound receiving hole 13, thereby achieving double sealing to prevent water from entering the inner cavity 4 of the housing 1 through the sound receiving hole 13.

[0030] A water-absorbing sponge 123 is provided in the middle of the outer wall of the protrusion 122 . When the protrusion 122 is located in the sound receiving hole 13 , the water-absorbing sponge 123 is tightly fitted with the side wall of the sound receiving hole 13 .

[0031] It can be understood that when water flows into the gap between the protrusion 122 and the sound receiving hole 13, the water in the gap is absorbed by the water-absorbing sponge 123, which can further prevent water from flowing into the inner cavity 4 of the shell 1, and the water-absorbing sponge 123 will expand after absorbing water. Thus, the water-absorbing sponge 123 will fit tightly with the side wall of the sound receiving hole 13, preventing water from flowing into the inner cavity 4 from the gap, thereby achieving a waterproof effect.

[0032] like Figure 5 As shown, the driving assembly 14 includes a rotating sleeve 141 threadedly connected to the outer wall of the housing 1, a rotating plate 142 rotatably connected within the rotating sleeve 141, and a through hole 143 formed by sequentially penetrating the rotating sleeve 141 and the rotating plate 142, and the rotating plate 142 is fixedly connected to the sliding frame 7.

[0033] It can be understood that the operator can rotate the rotating sleeve 141 in the forward direction, and the rotating sleeve 141 will drive the rotating plate 142 to move downward. The downward movement of the rotating plate 142 drives the sliding frame 7 to move downward, thereby making the sealing block 9 seal the sound transmission hole 5, and the sealing member 12 seal the sound receiving hole 13. The operator can rotate the rotating sleeve 141 in the reverse direction, and the rotating sleeve 141 will drive the rotating plate 142 to move upward, thereby no longer sealing the sound transmission hole 5 and the sound receiving hole 13, and the external environmental sound will be received by the microphone through the through hole 143 and the sound receiving hole 13 in turn.

[0034] A dustproof net 144 is provided at the through hole 143 .

[0035] It can be understood that when people use the Bluetooth headset, the dustproof net 144 can prevent dust from entering the inner cavity 4 of the shell 1 through the through hole 143 and the sound receiving hole 13, causing damage to the electronic components in the inner cavity 4.

[0036] like Figure 4 As shown, the waterproof Bluetooth headset also includes a locking component 15, which includes a slider 151 slidingly connected to the sliding frame 7, a roller 152 rotatably connected to the slider 151, a spring 153 arranged between the sliding frame 7 and the slider 151, and a groove 154 opened on the inner wall of the shell 1. When the sealing block 9 and the sealing member 12 respectively block the sound transmission hole 5 and the sound receiving hole 13, the roller 152 is located in the groove 154.

[0037] It can be understood that when the sliding frame 7 moves downward, it will drive the slider 151, the roller 152 and the spring 153 to move downward. In the initial state, the spring 153 is in a compressed state, and the roller 152 is against the inner wall of the shell 1. When the roller 152 moves downward to be aligned with the groove 154, the spring 153 will be reset from the compressed state. The reset of the spring 153 drives the slider 151 to move. The movement of the slider 151 drives the roller 152 to move to the groove 154. When the roller 152 is located in the groove 154, the sealing block 9 and the sealing member 12 also block and seal the sound transmission hole 5 and the sound receiving hole 13. Moreover, because the roller 152 is located in the groove 154, the sliding frame 7 is not easy to slide, thereby preventing the rotating sleeve 141 from being rubbed by external objects, causing the rotating sleeve 141 to rotate, thereby As a result, the sealing block 9 and the sealing member 12 do not have a good sealing effect. It can be understood that when people put the Bluetooth headset into their pockets, the rotating sleeve 141 is prone to friction with the fabric of the pocket during exercise, causing the rotating sleeve 141 to rotate, resulting in the sealing block 9 and the sealing member 12 not having a good seal. The roller 152 is stuck in the groove 154, making it difficult for the sliding frame 7 to move, so that a larger force is required to rotate the rotating sleeve 141, thereby allowing the sealing block 9 and the sealing member 12 to have a good seal. When the sealing block 9 and the sealing member 12 are no longer needed to seal the sound transmission hole 5 and the sound receiving hole 13 respectively, the operator can rotate the rotating sleeve 141 with greater force to move the sliding frame 7 upward, thereby causing the roller 152 to disengage from the groove 154.
