[0024] Embodiment 1: Reference Figure 1 and Figure 2 Embodiment 1 of the present application discloses an OWS wearable headset, comprising an earphone body 1, a connecting part 2 and a sound-emitting part 3.

[0025] The sound-emitting part 3 includes a speaker part 31 and a sound guide tube 32. The speaker part 31 includes a sound-emitting shell 311 connected to the connecting part 2 and a sound-emitting component 312 installed in the sound-emitting shell 311. The sound-emitting shell 311 forms a sound-receiving cavity 3111. One side of the sound-emitting shell 311 is convexly arranged to form a sound outlet 3112 for matching the ear hole. The sound outlet 3112 is provided with a first sound outlet 3115 connected to the sound-receiving cavity 3111.

[0026] like Figure 1 and Figure 3 The connecting part 2 includes an ear hook part 21 and a connecting tube 22, and the connecting tube 22 is used to connect the ear hook part 21 and the sound-emitting shell 311. The sound-emitting shell 311 is located on the side of the connecting tube 22 facing the ear hook part 21. The connecting tube 22 is provided with a second sound outlet 321 at one end away from the ear hook part 21, and the sound guide tube 32 is located in the connecting tube 22, and the sound guide tube 32 communicates with the sound cavity 3111 and the second sound outlet 321.

[0027] A wire post 4 is provided at one end of the connecting tube 22 facing the ear hook portion 21 , and the wire post 4 is used to guide the wire of the earphone body 1 to pass through the ear hook portion 21 and penetrate into the sound-generating housing 311 .

[0028] When in use, the earphone is hung between the ear and the head through the ear hook 21. At this time, the earphone body 1 is located behind the ear, and the sound-emitting part 3 is located at the ear hole. The first sound outlet 3115 is arranged at a position directly opposite the ear hole, so that the sound output by the sound-producing component 312 in the forward direction can be clearly heard. The second sound outlet 321 is located at the ear hole and is arranged diagonally downward, so that the sound output by the sound-producing component 312 in the reverse direction enters the sound guide tube 32 through the sound cavity 3111, forming an ambient sound in the external environment of the ear to enhance the bass effect. And because the treble is directional and the bass is almost non-directional, the treble leaves the vicinity of the ear hole in the axial direction of the sound guide tube 32, so that the external ambient sound around the ear hole is more bass, thereby further improving the bass effect.

[0029] Specifically, Figure 1 and Figure 3, a slot is provided on the side wall of the sound-emitting shell 311, and the slot is a through slot. The side wall of the connecting tube 22 is embedded in the slot. The sound-emitting shell 311 and the connecting tube 22 are fixedly arranged as one body. The connecting tube 22 is opened at one end away from the ear hook 21, and the sound guide tube 32 is detachably connected to the open end of the connecting tube 22 by means of a block or a threaded connection. The sound guide tube 32 closes the open end of the connecting tube 22. The second sound outlet 321 is located at the end of the sound guide tube 32 away from the connecting tube 22. A first sound transmission groove 221 is provided at the position of the connecting tube 22 corresponding to the slot, and a second sound transmission groove 322 is provided at the position of the sound guide tube 32 corresponding to the first sound transmission groove 221. The sound waves in the sound chamber 3111 enter the sound guide tube 32 through the first sound transmission groove 221 and the second sound transmission groove 322, and are output to the environment from the second sound outlet 321 after passing through the sound guide tube 32. By providing sound guide tubes 32 of different lengths and diameters, the acoustic performance of different frequency bands can be enhanced, and the sound intensity of different frequency bands can be increased or weakened according to actual needs, thereby improving the sound quality of the product.

[0030] Further, such as Figure 2 As shown, the sound-emitting housing 311 includes a main housing 3113 with an opening at one end and a closing cover 3114 for closing the opening of the main housing 3113, and the sound outlet 3112 is located on the closing cover 3114. The closing cover 3114 is detachably connected to the open end of the main housing 3113. The detachable connection between the closing cover 3114 and the main housing 3113 can be in the form of a threaded connection, a snap connection, a bolt connection, etc. By replacing the closing cover 3114, a sound outlet 3112 with different curvatures can be selected, so that the sound outlet 3112 can better match the ear holes and auricles of different people, thereby improving the wearing comfort.

[0031] Because in a closed environment, the sound pressure received by the human ear is proportional to the displacement of the vibration volume of the speaker unit; in the case of leakage, the sound pressure received by the human ear is proportional to the vibration volume velocity of the speaker unit; in the case of severe leakage or similar to the radiation of the speaker, the sound pressure received by the human ear is proportional to the acceleration of the vibration volume of the speaker unit. If you want to further improve the bass effect, you can also choose a closed cover 3114 with a larger curvature, so that the sound output end 3112 extends from the outside of the ear hole to the inside of the ear hole, thereby improving the bass effect.

[0032] Further, such as Figure 4 and Figure 5 As shown, the wire post 4 closes one end of the connecting tube 22. The setting of the wire post 4 closes the passage between the connecting tube 22 and the ear hook 21, so that the sound waves entering the connecting tube 22 are transmitted toward the second sound outlet 321 in a designated direction as much as possible, further improving the sound quality.

[0033] Further, such as Figure 4 and Figure 5As shown, the connecting tube 22 is rotatably connected to the ear hook 21 through the wire rod 4. After the earphone is hung on the ear, the wire rod 4 can be rotated relative to the ear hook 21 to adjust the angle of the sound output end 3112 relative to the ear hole, so that the sound output end is adapted to different ear shapes and the comfort of use is improved.

[0034] Specifically, Figure 4 and Figure 5 As shown, a first annular groove 41 is provided on the outer wall of one end of the conductor post 4, and a first clamping ring 222 is provided on the inner wall of the connecting tube 22 to slide and clamp in the first annular groove 41, so that the conductor post 4 is rotatably connected to the connecting tube 22. A second annular groove 41 is provided on the outer wall of the end of the conductor post 4 facing away from the connecting tube 22, and a second clamping ring 211 is provided on one end of the hanging ear portion 21, and the second clamping ring 211 is slidably clamped in the second annular groove 41, so that the conductor post 4 is rotatably connected to the hanging ear portion 21, and the connecting tube 22 is rotatably connected to the hanging ear portion 21. The relative fixation between the connecting tube 22 and the hanging ear portion 21 is achieved by the friction between the conductor post 4, the connecting tube 22 and the hanging ear portion 21.

[0035] Further, if Figure 4 and Figure 5 As shown, in order to reduce sound leakage, the second clamping ring 211 extends into the connecting tube 22, and the end of the hanging ear portion 21 abuts against the connecting tube 22. The second clamping ring 211 is provided with a plurality of deformation grooves along its axial direction to divide the second clamping ring 211 into a plurality of ring connecting rods. A clamping block 2111 is provided at the outward end of the ring connecting rod, and a third ring groove 223 is provided on the inner wall of the connecting tube 22. The clamping block 2111 is slidably clamped in the third ring groove 223. Furthermore, a sealing gasket (not shown in the figure) is provided at the end of the connecting tube 22 facing the hanging ear portion 21, thereby improving the sealing between the connecting tube 22 and the hanging ear portion 21 and reducing sound leakage.

[0036] Embodiment 2: The difference between Example 2 and Example 1 is that Figure 6 As shown, the sound-emitting shell 311 is connected to the connecting tube 22 by sliding along the sound-emitting direction of the first sound outlet; when the earphone is worn, the sound-emitting shell 311 slides relative to the connecting tube 22, and the distance between the first sound outlet 3115 and the ear hole changes.

[0037] Since the shape of each user's ear is different, it is difficult to ensure that the distance between the sound-producing end and the ear hole is the optimal distance after the earphone is hung on the ear. At this time, the sound-producing shell 311 can be slid relative to the connecting tube 22 so that the distance between the first sound outlet 3115 and the ear hole meets the user's requirements. If the user pays more attention to the bass sound quality, the sound-producing shell 311 can be moved toward the ear hole so that the sound outlet end 3112 fits the ear hole as closely as possible to form a nearly closed chamber, thereby improving the bass. If the user pays more attention to wearing comfort, the sound-producing shell 311 can be moved away from the ear hole to reduce the discomfort caused by the sound-producing shell 311 contacting the ear hole or even pressing against the ear hole, thereby improving the comfort of use.

[0038] Specifically, a movable groove 3116 is provided on the side wall of the sound-emitting housing 311, and the side wall of the connecting pipe 22 is embedded in the movable groove 3116. The width of the movable groove 3116 is greater than the diameter of the connecting pipe 22. The groove wall of the movable groove 3116 and the pipe wall of the connecting pipe 22 are connected and sealed by a rubber movable sheet 5. The rubber movable sheet 5 includes a plurality of folding units connected to each other, and the rubber movable sheet 5 is in a wave-shaped broken line.

[0039] When adjusting, first adjust the sound-generating housing 311 to the position closest to the connecting tube 22, then put the earphone on the ear, at which time the distance between the sound-generating end and the ear hole is the farthest. Then fix the connecting tube 22 with one finger, and push the sound-generating housing 311 inward with one finger until the distance between the sound-generating end and the ear hole is adjusted to meet the user's requirements, which is easy to operate. At the same time, the rubber movable sheet 5 also has a certain sealing performance, reducing the possibility of sound leakage.

[0040] Embodiment 3: The difference between Example 3 and Example 1 is that Figure 7 and Figure 8 As shown, the connecting pipe 22 and the sound-generating housing 311 are connected through the connecting housing 6, which includes a connecting outer shell 62 fixedly connected to the connecting pipe 22 and a connecting inner shell 61 rotatably connected to the connecting outer shell 62. The connecting inner shell 61 is sleeved outside the sound-generating housing 311, and the connecting housing 6 is used to convert the rotary pair into a linear pair and output it to the sound-generating housing 311. The connecting inner shell 61 is provided with at least four first through grooves 611 for connecting the first sound-containing groove and the second sound-containing groove along its circumference. The connecting outer shell 62 is provided with at least one second through groove 621 for connecting the first sound-containing groove and the second sound-containing groove.

[0041] Specifically, the connecting inner shell 61 is rotatably connected to the connecting outer shell 62 and axially fixed to the connecting outer shell 62, and one end of the connecting inner shell 61 passes through the connecting outer shell 62. The sound-emitting shell 311 is located in the connecting inner shell 61 and is slidably connected to the connecting inner shell 61 along the sound-emitting direction of the first sound outlet 3115. The connecting outer shell 62 is provided with a limit block 622, and the outer wall of the sound-emitting shell 311 is provided with a limit groove 3117 along the sound-emitting direction of the first sound outlet 3115 thereof, and the limit block 622 is slidably connected in the limit groove 3117, so that the sound-emitting shell 311 is slidably connected to the connecting outer shell 62 along the sound-emitting direction of the first sound outlet 3115 and is fixedly connected to the connecting outer shell 62 along the circumferential direction.

[0042] like Figure 8 and Fig. 9 As shown, the side wall of the connecting inner shell 61 is provided with a guide groove 612, which includes a vertical groove 6121 arranged along the axial direction of the connecting inner shell 61 and a transverse groove 6122 arranged along the circumferential direction of the connecting inner shell 61. Two transverse grooves 6122 are provided and respectively connect the two ends of the vertical groove 6121. A guide block 3118 slidably connected to the vertical groove 6121 is provided outside the sound-generating housing 311.

[0043] When adjustment is needed, the inner shell 61 is directly screwed relative to the outer shell 62. At this time, the wall of the guide groove 612 exerts a driving force on the guide block 3118, thereby driving the sound-generating housing 311 to slide relative to the outer shell 62 to complete the adjustment. If the guide block 3118 is rotated into the transverse groove 6122, it means that the movement of the sound-generating housing 311 relative to the outer shell 62 has reached the limit and cannot move any further, thereby preventing the first sound transmission groove 221 on the sound-generating housing 311 from being blocked due to excessive adjustment.

[0044] like Figure 7 and Fig. 9 As shown, in order to make the connection between the sound-generating housing 311, the connecting inner housing 61 and the connecting outer housing 62 more stable, at least two groups of limiting grooves 3117 and limiting blocks 622 are provided. At least two groups of guide grooves 612 and guide blocks 3118 are also provided.
