[0018] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.
[0019] This utility model embodiment provides a Bluetooth headset 1000, such as... Figure 1 - Figure 2 As shown, the Bluetooth headset 1000 includes a housing 10 and a charging contact assembly 20. The housing 10 includes an insertion portion 11, on which a sound outlet structure 111 is provided. The insertion portion 11 is used to fit into the ear so that the sound outlet structure 111 is located in the ear canal. The charging contact assembly 20 is disposed next to the sound outlet structure 111, so that the charging contact assembly 20 can be suspended in the ear canal. This application can solve the problem in the prior art that the charging contact assembly of Bluetooth headsets is easily covered by sweat and epidermal secretions, leading to oxidation and rust. The Bluetooth headset 1000 optimizes the position of the charging contact assembly 20 to avoid contact between the charging contact assembly 20 and sweat and epidermal secretions, thereby extending the service life of the Bluetooth headset 1000.
[0020] Specifically, the insertion part 11 is worn behind the ear, forming a sealed space with the inner wall of the ear canal. Since both the charging contact assembly 20 and the sound outlet structure 111 are located in the ear canal, compared to embodiments in the prior art where the charging contact assembly is placed outside the ear canal, the insertion part 11 acts as a physical barrier, effectively preventing external sweat and secretions from entering the interior, thus avoiding contact between the charging contact assembly 20 and contaminants. Simultaneously, the charging contact assembly 20 is suspended within the ear canal, meaning it does not contact the ear wall, further reducing the possibility of contact between the charging contact assembly 20 and secretions, reducing oxidation and corrosion of the charging contact assembly 20, and extending the service life of the Bluetooth headset 1000.
[0021] Reference Figure 1 and Figure 2 In one embodiment, the sound outlet structure 111 is annular, and the insertion part 11 includes a central platform 114 surrounded by the sound outlet structure 111, with the charging contact assembly 20 disposed on the central platform 114. This arrangement positions the charging contact assembly 20 at the center of the sound outlet structure 111, allowing it to be sufficiently away from the ear canal, further avoiding direct contact with the skin. Furthermore, the annular sound outlet structure 111 itself also acts as an insulator, further protecting the centrally located charging contact assembly 20 from contamination by sweat or secretions.
[0022] Preferably, the sound outlet structure 111 is located in the central area of the insertion part 11. This optimizes the overall layout of the Bluetooth headset 1000, making the center of gravity of the Bluetooth headset 1000 more stable when worn, and making it easier for the insertion part 11 to fit snugly into the ear canal, thus improving the secure fit of the Bluetooth headset 1000.
[0023] In one embodiment, the insertion part 11 includes an outer peripheral surface, and the sound outlet structure 111 is a sound outlet group 1111 disposed on the outer peripheral surface. The sound outlet group 1111 includes a plurality of sound outlets, which are arranged in a circular pattern.
[0024] In one embodiment, the central platform 114 is recessed so that the sound outlet structure 111 protrudes beyond the charging contact assembly 20. With this configuration, the charging contact assembly 20 is located on the recessed central platform, and its plane is lower than the surrounding plane of the sound outlet structure 111. This provides additional physical shielding for the charging contact assembly 20, making it less susceptible to direct contact or contaminant intrusion, thereby further enhancing the corrosion and oxidation resistance of the Bluetooth headset 1000.
[0025] Reference Figure 3 In one embodiment, an isolation groove 112 is provided between the sound outlet structure 111 and the charging contact assembly 20, and the isolation groove 112 surrounds the charging contact assembly 20. This arrangement, with the isolation groove 112 surrounding the charging contact assembly 20, effectively prevents contaminants from contacting the charging contact assembly 20, thereby further enhancing the corrosion and oxidation resistance of the Bluetooth headset 1000 and extending its service life.
[0026] In one embodiment, the charging contact assembly 20 defines a mounting area; the mounting area has a certain distance from the ear canal wall, which is greater than or equal to 2mm and less than or equal to 3mm. This arrangement, by reasonably controlling the mounting area and the ear canal wall, ensures that the charging contact assembly 20 is suspended in the ear canal, preventing it from contacting the ear canal wall; it also maintains the compact layout of the overall Bluetooth headset 1000, resulting in a more rational overall design.
[0027] Reference Figure 3 In one embodiment, the charging contact assembly 20 includes a first contact 21 and a second contact 22, which are symmetrically arranged on both sides of the central axis of the insertion portion 11. This symmetrical arrangement helps to optimize the weight distribution of the internal components of the Bluetooth headset 1000, so that the overall center of gravity is located at the center of the insertion portion 11, thereby improving the balance and stability when wearing it.
[0028] Reference Figure 4 In one embodiment, the insertion part 11 is provided with an annular groove 113, which is connected to the interior of the insertion part 11. A sound cover 115 is installed in the annular groove 113, and a sound outlet structure 111 is provided on the sound cover 115. Two locking holes 1141 are provided on the center platform 114, and the first contact 21 and the second contact 22 are respectively installed in the two locking holes 1141. With this configuration, the locking holes 1141 can limit the installation of the first contact 21 and the second contact 22, ensuring the relative position of the first contact 21 and the second contact 22 in the insertion part 11, improving the connection stability between the charging contact assembly 20 and the insertion part 11, and improving the overall structural reliability of the Bluetooth headset 1000.
[0029] In one embodiment, the speaker cover 115 is detachably connected to the annular groove 113. This allows the speaker cover 115 to be installed or removed, facilitating cleaning of the Bluetooth headset 1000 and also making replacement and maintenance easier.
[0030] There are many ways to detachably connect the sound cover 115 to the annular groove 113, such as snap-fit connection, magnetic connection, threaded connection, etc., and no limitation is made on its setting method here.
[0031] In one embodiment, the speaker cover 115 may be made of metal. Preferably, the speaker cover 115 is made of stainless steel to prevent oxidation and rust.
[0032] Reference Figure 5 In one embodiment, the Bluetooth headset 1000 further includes a dynamic driver unit 30, which is disposed within the insertion portion 11 and located on the side of the charging contact assembly 20 facing away from the ear canal. The dynamic driver unit 30 includes a diaphragm 31, which has a diaphragm portion 311. The diaphragm portion 311 is annular and is disposed opposite to the sound outlet structure 111. In the orientation of the sound outlet structure 111, the projection of the charging contact assembly 20 is surrounded by the projection of the diaphragm portion 311. With this arrangement, since the diaphragm portion 311 is annular, the charging contact assembly 20 is disposed in the central region of the diaphragm portion 311. That is, the charging contact assembly 20 is not located on the sound propagation path of the dynamic driver unit 30, thereby effectively avoiding the obstruction and interference of the charging contact assembly 20 on the sound wave transmission and ensuring the sound quality of the Bluetooth headset 1000.
[0033] Reference Figure 6 In one embodiment, the Bluetooth headset 1000 further includes a support 40, which is disposed within the insertion portion 11 and located next to the dynamic driver unit 30. The support 40 includes a fixing arm 41, which is suspended between the dynamic driver unit 30 and the charging contact assembly 20, and the charging contact assembly 20 is mounted on the fixing arm 41. This arrangement allows the fixing arm 41 of the support 40 to provide stable support for the charging contact assembly 20, resulting in better connection stability between the charging contact assembly 20 and the insertion portion 11.
[0034] In one embodiment, the fixed arm 41 is provided with a limiting hole 411, and the insertion part 11 is provided with a limiting post (not shown in the figure), which is inserted into the limiting hole 411. In this way, the limiting post and the limiting hole 411 cooperate to limit the relative position of the fixed arm 41 in the insertion part 11, thereby improving the connection stability of the bracket 40.
[0035] In one embodiment, the bracket 40 further includes a support platform 42, which is located on the side of the fixed arm 41 away from the sound outlet structure 111, and the support platform 42 is spaced apart from the fixed arm 41. The moving coil unit 30 is mounted on the support platform 42. With this arrangement, the support platform 42 can limit the installation of the moving coil unit 30, thereby improving the connection stability of the moving coil unit 30.
[0036] In one embodiment, the Bluetooth headset 1000 further includes a locking component and a fixing component. The insertion portion 11 includes an outer peripheral surface that is covered by the ear, and the outer peripheral surface includes a snap-fit end. The locking component includes a locking member, which includes a locking part installed inside the housing and an operating part connected to the locking part. The operating part is exposed on the side of the outer peripheral surface facing away from the user's ear. The fixing component includes an ear wing and a first elastic member. The ear wing is movably disposed at the insertion portion 11, and the ear wing and the snap-fit end are spaced apart and opposite to each other in a first direction. The first elastic member is connected to the ear wing, and a connecting structure is provided at the ear wing. The connecting structure cooperates with the locking part to lock the ear wing in the insertion portion 11. The locking member is movably connected to the housing so that when the operating part is touched, the locking part can move and unlock with the connecting structure. At this time, the first elastic member can drive the ear wing to pop out of the insertion portion 11. The Bluetooth headset 1000 has strong compatibility and can greatly improve the comfort of the user during wearing.
[0037] Specifically, the Bluetooth headset 1000 is equipped with a locking component. The locking member of the locking component can lock the ear wing using the locking ear wing connection structure, so that the ear wing is locked in the insertion part 11. When the user's ears are small, the ear wing can be locked in the insertion part 11 before wearing. Since there is no ear wing to affect the ear, it is easy to adjust the relative position of the clip end in the ear. After the adjustment is completed, since the operating part is exposed on the outer peripheral surface facing away from the user's ear, the user can operate the operating part to move the locking member relative to the shell, the connection structure separates from the locking part, and the locking member unlocks the ear wing. At this time, the ear wing pops out under the action of the first elastic member and abuts against the ear, thereby completing the Bluetooth headset 1000 being clipped into the ear. Compared with the prior art embodiment where the ear wing needs to rub against the ear frequently, during the entire wearing process, the ear wing does not contact the ear when the user adjusts the position of the Bluetooth headset 1000, which is more effortless. After the adjustment is completed, the ear wing is directly unlocked to complete the Bluetooth headset 1000 clipping in. The ear wing does not rub against the ear, making the user's wearing process more comfortable. Furthermore, since the locking mechanism is exposed outside the shell, users can unlock the ear wings by operating the locking mechanism, which makes it easier to operate and allows users to be more certain whether the ear wings are accurately locked, resulting in a better user experience.
[0038] In addition, the locking component also makes it easier to store the Bluetooth headset 1000, reducing the space occupied by the Bluetooth headset 1000. It also makes it easier to place the Bluetooth headset 1000 in the charging case, which also helps to reduce the size of the Bluetooth headset 1000 and improve the portability of the product.
[0039] It should be understood that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Those skilled in the art can modify the technical solutions described in the above embodiments, or make equivalent substitutions for some of the technical features; and all such modifications and substitutions should fall within the protection scope of the appended claims of this utility model.
