[0031] The specific implementation of this application is described in more detail below in conjunction with specific embodiments:

[0032] First, please refer to Figure 6The concha cavity 200' is an area located between the auricle 300' and the tragus 400' and connected to the ear canal 100'. The concha cavity 200', the auricle 300', the tragus 400' and the ear canal 100' are all general terms for the ear structure. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0033] See also Figure 1 , Figure 2 , Figure 3 The embodiment of the present application provides a Bluetooth headset, which includes a shell 100 for being worn in the concha cavity 200' and an earplug 200 connected to the front side of the shell 100 and for being worn in the ear canal 100'. The shell 100 includes a shell body 110, a first limiting portion 120 connected to the front side of the shell body 110 and protruding forward, a second limiting portion 130 connected to the lower side of the shell body 110 and protruding downward, and a third limiting portion 140 connected to the rear side of the shell body 110, the third limiting portion 140 protrudes backward and upward, the first limiting portion 120, the second limiting portion 130 and the third limiting portion 140 are all in contact with the cavity wall of the concha cavity 200', and together fix the shell 100 to the concha cavity 200'.

[0034] It should be noted that, on the basis of using the side connected to the earplug 200 as the front side of the shell 100, the shell 100 is provided with a first limiting portion 120 protruding forward on the front side of the shell body 110. When the earplug 200 is worn in the ear canal 100' and the shell 100 is worn in the concha cavity 200', the first limiting portion 120 can abut against the front wall of the concha cavity 200' and form a holding force on the front side of the concha cavity 200'. The shell 100 is also provided with a second limiting portion 130 protruding downward on the lower side of the shell body 110. Through the second limiting portion 130, the earplug 200 can be worn in the ear canal 100' and the shell 100 can be worn in the concha cavity 200'. 0 When the earplug 200 is worn in the ear canal 100' and the shell 100 is worn in the concha cavity 200', it can abut against the lower wall of the concha cavity 200' and form a holding force on the lower side of the concha cavity 200'; the shell 100 is also provided with a third limiting portion 140 protruding backward and upward on the upper rear side of the shell body 110, and the third limiting portion 140 can abut against the upper rear wall of the concha cavity 200' when the earplug 200 is worn in the ear canal 100' and the shell 100 is worn in the concha cavity 200', and form a holding force on the upper rear side of the concha cavity 200'. Based on this, the first limiting portion 120, the second limiting portion 130 and the third limiting portion 140 will respectively form different resisting forces on the concha cavity 200' in three different directions intersecting at one point, and the resisting forces are balanced at a common point, so that when the earplug 200 is worn in the ear canal 100' and the shell 100 is worn in the concha cavity 200', the wearing state of the Bluetooth headset can be effectively, reliably and stably maintained, that is, the wearing stability of the Bluetooth headset is effectively guaranteed and improved, and the Bluetooth headset can be effectively prevented from falling from the ear. In addition, the shell 100 is mainly fixed by the first limiting portion 120, the second limiting portion 130 and the third limiting portion 140, thereby effectively reducing the total contact area between the shell 100 and the concha cavity 200', and reducing the total pressure of the shell 100 on the concha cavity 200', thereby greatly improving the wearing comfort of the Bluetooth headset.

[0035] In addition, by disposing the first limiting portion 120, the second limiting portion 130 and the third limiting portion 140, the housing 100 as a whole can be more compatible with the concha cavity 200', thereby further improving the wearing comfort of the Bluetooth headset.

[0036] In summary, when the earplug 200 is worn in the ear canal 100' and the housing 100 is worn in the concha cavity 200', the first limiting portion 120 abuts against the front wall of the concha cavity 200', the second limiting portion 130 abuts against the lower wall of the concha cavity 200', and the third limiting portion 140 abuts against the upper rear wall of the concha cavity 200', thereby forming a balanced abutting force in three intersecting directions, so that the housing 100 can be stably worn in the concha cavity 200. 0', effectively ensuring the wearing stability of the Bluetooth headset when worn on the ear. At the same time, through the arrangement of the first limiting portion 120, the second limiting portion 130 and the third limiting portion 140, the shell 100 and the cavum concha 200' will be more adaptable, which not only effectively reduces the total contact area between the shell 100 and the cavum concha 200', but also effectively reduces the total pressure of the shell 100 on the cavum concha 200', reduces the risk of discomfort in the user's ears, and improves the wearing comfort of the Bluetooth headset.

[0037] See also Figure 1 , Figure 2 , Figure 3 In this embodiment, the shell body 110 is provided with a decompression portion 111 between the first limiting portion 120 and the second limiting portion 130. The decompression portion 111 is arranged in alignment with the earplug 200 and is used to reduce the pressure of the shell 100 on the concha cavity 200' and the ear canal 100'. It should be noted here that the decompression portion 111 is recessed between the first limiting portion 120 and the second limiting portion 130, that is, recessed on the front and lower side of the shell body 110. Based on the setting of the decompression portion 111, when the earplug 200 is worn in the ear canal 100' and the shell 100 is worn in the concha cavity 200', the front and lower side of the shell body 110 can be avoided from contacting the concha cavity 200' and the tragus 400', thereby effectively reducing the pressure value between the front and lower side of the shell body 110 and the concha cavity 200', the tragus 400' and the ear canal 100', thereby further reducing the total pressure of the shell 100 on the concha cavity 200', the tragus 400' and the ear canal 100', so as to further improve the wearing comfort of the Bluetooth headset, and also facilitate the detachment of the Bluetooth headset when the user detaches the shell 100 from the concha cavity 200' and the earplug 200 from the ear canal 100', which can further prevent the Bluetooth headset from causing damage to the ear.

[0038] See also Figure 1 , Figure 2 , Figure 3In this embodiment, the first limiting portion 120 has a first limiting arc surface 121 for contacting the cavity wall of the cavity concha 200', the second limiting portion 130 has a second limiting arc surface 131 for contacting the cavity wall of the cavity concha 200', and the third limiting portion 140 has a third limiting arc surface 141 for contacting the cavity wall of the cavity concha 200'. The curvature of the third limiting arc surface 141 is greater than that of the first limiting arc surface 121, and greater than that of the second limiting arc surface 131. It should be noted that, by setting the first limiting arc surface 121, the second limiting arc surface 131 and the third limiting arc surface 141, the housing 100 can be adaptively contacted with the cavity concha 200' when worn in the cavity concha 200', and damage to the cavity concha 200' can be effectively avoided, thereby further improving the wearing comfort of the Bluetooth headset. By setting the curvature of the third limiting arc surface 141 to be greater than that of the first limiting arc surface 121 and greater than that of the second limiting arc surface 131, on the one hand, the overall shape of the shell 100 can be more compatible with the cavum concha 200', so as to further ensure and improve the wearing comfort of the Bluetooth headset; on the other hand, on the basis of ensuring that the supporting force of the third limiting portion 140 on the cavum concha 200' can balance the supporting forces of the first limiting portion 120 and the second limiting portion 130 on the cavum concha 200', the contact area between the third limiting portion 140 and the cavum concha 200' can be enlarged to reduce the stress concentration phenomenon between the third limiting portion 140 and the cavum concha 200', so as to balance the supporting forces of each point of the third limiting portion 140 on the cavum concha 200', so as to further improve the wearing comfort of the Bluetooth headset and avoid discomfort to the user.

[0039] See also Figure 4 , Figure 5 In this embodiment, the Bluetooth headset further includes a touch screen 300 connected to the side of the housing 100 away from the earplug 200, and the touch screen 300 is used for the user to touch and control the Bluetooth headset. It should be noted that the touch screen 300 is arranged on the side of the housing 100 away from the earplug 200, so that when the earplug 200 is worn in the ear canal 100' and the housing 100 is worn in the concha cavity 200', the user can control the Bluetooth headset by touching, pressing, etc. on the touch screen 300. Based on this, the Bluetooth headset can be turned on, off, paused, played, audio switching, volume adjustment, etc. can be conveniently realized, thereby greatly improving the performance of the Bluetooth headset and improving the convenience of operation of the Bluetooth headset.

[0040] See also Figure 3 , Figure 4 , Figure 5In this embodiment, the shell 100 also includes a mounting structure 150 connected to the side of the shell body 110 facing away from the earplug 200 and used to mount the touch screen 300, and a transition structure 160 transitionally connected between the shell body 110 and the mounting structure 150. The cross-sectional size of the mounting structure 150 is smaller than the cross-sectional size of the shell body 110, and the cross-sectional size of the transition structure 160 is gradually reduced from the side where it is connected to the shell body 110 to the side where it is connected to the mounting structure 150. It should be noted here that the touch screen 300 is installed on the mounting structure 150, and the transition structure 160 is transitionally connected between the shell body 110 and the mounting structure 150 so that the mounting structure 150 is arranged outwardly relative to the shell body 110. Based on this, when the earplug 200 is worn in the ear canal 100' and the shell 100 is worn in the concha cavity 200', the touch screen 300 will be relatively located on the outside of the concha cavity 200', so that it is convenient for the user to touch, press, and perform other operations on the touch screen 300, thereby further improving the operational convenience of the touch screen 300 and further improving the performance of the Bluetooth headset.

[0041] It should also be noted here that by setting the cross-sectional size of the mounting structure 150 smaller than the cross-sectional size of the shell body 110, and gradually setting the cross-sectional size of the transition structure 160 from the side where it is connected to the shell body 110 to the side where it is connected to the mounting structure 150, the touch screen 300 can be distinguished from the shell body 100. In this way, the user can accurately perform blind operation on the touch screen 300 when the earplug 200 is worn in the ear canal 100' and the shell 100 is worn in the concha cavity 200', thereby further improving the operational convenience of the touch screen 300 and further improving the performance of the Bluetooth headset.

[0042] See also Figure 1 , Figure 3 In this embodiment, the mounting structure 150 has a touch working surface 151 for the user to touch, and the touch working surface 151 is a plane. It should be noted that the plane touch working surface 151 not only facilitates the user to accurately and blindly operate the touch screen 300 when the earplug 200 is worn in the ear canal 100' and the housing 100 is worn in the concha cavity 200', so as to further improve the convenience of operation of the touch screen 300, but also facilitates the touch screen 300 to accurately identify instructions according to the user's touch and press actions, thereby improving the accuracy of the Bluetooth headset's judgment of touch commands, thereby further improving the performance of the Bluetooth headset.

[0043] See also Figure 2In this embodiment, the shape of the mounting structure 150 is set in an elliptical shape. It should be noted here that by setting the shape of the mounting structure 150 in an elliptical shape, on the one hand, the contactable area of ​​the touch screen 300 can be effectively guaranteed and increased, that is, the touchable area of ​​the touch screen 300 can be guaranteed and increased, so that the user can accurately perform blind operations on the touch screen 300 when the earplug 200 is worn in the ear canal 100' and the shell 100 is worn in the concha cavity 200'; on the other hand, it can also facilitate the touch screen 300 to accurately judge the instructions of each touch area, so as to improve the accuracy of the Bluetooth headset's judgment of the touch command. Therefore, through the setting of this embodiment, the operating convenience of the touch screen 300 can be further improved, and the use performance of the Bluetooth headset can be further improved.

[0044] See also Figure 2 In this embodiment, the mounting structure 150 is arranged to extend in the vertical direction. Through the arrangement of this embodiment, the touch screen 300 can further accurately judge the instructions of each touch area, so as to improve the accuracy of the Bluetooth headset's judgment of the touch instruction, thereby further improving the convenience of operation of the touch screen 300 and the use performance of the Bluetooth headset.

[0045] See also Figure 1 , Figure 4 , Figure 5 In this embodiment, the touch screen 300 includes a touch portion 310 and a positioning portion 320 connected to the touch portion 310. The mounting structure 150 is provided with a touch limiting groove 152 and a touch positioning groove 153 connected to the touch limiting groove 152 on its side facing the earplug 200. The touch limiting groove 152 is used to cooperate with the touch portion 310 in a limiting manner, and the touch positioning groove 153 is used to cooperate with the positioning portion 320 in a limiting manner to achieve the positioning of the touch screen 300. It should be noted here that the mounting structure 150 realizes the limited installation of the touch screen 300 through the touch limit groove 152 and the touch part 310, and realizes the positioning installation of the touch screen 300 through the touch positioning groove 153 and the positioning part 320. That is, based on the setting of this embodiment, the touch screen 300 and the mounting structure 150 will have a unique installation direction, which can further facilitate the touch screen 300 to accurately judge the instructions of each touch area, so as to improve the accuracy of the Bluetooth headset's judgment of touch instructions, and further improve the performance of the Bluetooth headset.

[0046] It is additionally noted that the touch portion 310 can be divided into touch areas representing different commands according to the touch function requirements, and the operations performed by the user in different touch areas can represent different commands. For example, when the user touches the upper touch area, the touch screen 300 can determine that the command is "switch to the previous song", and when the user touches the lower touch area, the touch screen 300 can determine that the command is "switch to the next song", etc. On this basis, if the above embodiment is adopted, the accuracy of the Bluetooth headset's judgment of the touch command can be further improved, and the performance of the Bluetooth headset can be further improved.

[0047] See also Figure 1 , Figure 2 , Figure 4 In this embodiment, the transition structure 160 is provided with an indicating light-transmitting hole 161, and the Bluetooth headset further includes an indicator light 400 disposed between the shell body 110 and the transition structure 160. The indicator light 400 is arranged in alignment with the indicating light-transmitting hole 161 and is used to indicate the operating status of the touch screen 300. It should be noted that when the user touches or presses the touch screen 300 to control the Bluetooth headset, the indicator light 400 can indicate the operating status of the touch screen 300 in real time by flashing, being always on, etc., so as to facilitate the user to judge the current status of the Bluetooth headset.
