It should be noted that when a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a centrally arranged component at the same time.
[0035] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.
[0036] Embodiment 1:
[0037] See also Figure 1-Figure 5The embodiment of the utility model provides an open-type earphone with adjustable connectivity, including an earphone main body 10 and an ear cap main body 20 connected to the earphone main body 10, the ear cap main body 20 including a cavity 21, a sound outlet 22 and a connecting portion 23, a first side of the sound outlet 22 is connected to the cavity 21, a second side of the sound outlet 22 is connected to a space outside the earphone for transmitting sound, a connecting piece 230 is provided on the connecting portion 23, the connecting piece 230 is used for connecting the cavity 21 with the outside world, the connecting piece 230 can adjust the connectivity between the cavity 21 and the outside world, when the cavity 21 is connected with the outside world, the first side of the sound outlet 22 is connected to the outside world through the cavity 21 and the connecting portion 23 in sequence, and the connectivity between the cavity 21 and the outside world can be continuously adjusted, thereby achieving adjustable control of the open-type effect.
[0038] It should be noted that the sound outlet 22 of the present embodiment is an elliptical sound outlet 22. In other embodiments, the sound outlet 22 may be a sound outlet 22 of other shapes besides the elliptical sound outlet 22. Designers may select a sound outlet 22 of a suitable shape according to actual conditions. The present embodiment does not limit the shape of the sound outlet 22.
[0039] In this embodiment, the connecting portion 23 includes an outer nesting 231 connected to the earphone body 10 and an inner nesting 232 disposed in the outer nesting 231, and a sound outlet 24 is disposed on one side of the inner nesting 232;
[0040] The outer nesting 231 can rotate relative to the inner nesting 232, and the connecting piece 230 is respectively arranged on the inner nesting 232 and the outer nesting 231 and is connected with the cavity 21. The degree of overlap between the inner nesting 232 and the connecting piece 230 on the outer nesting 231 is adjusted by rotation, and the degree of connectivity between the cavity 21 and the outside world is adjusted. By rotating and adjusting the overlap between the connecting piece 232 on the inner nesting 231 and the outer nesting 230, the degree of connectivity between the cavity 21 and the outside world can be continuously adjusted to achieve adjustable control of the open effect. The user can select the appropriate degree of openness according to environmental needs. When the noise is loud, the connectivity is increased to help balance the internal and external sound pressures and avoid hearing damage. In some usage scenarios, such as when the user wears headphones while riding or walking, partial or full connectivity can be achieved, and the user can also hear the sound of the external environment to prevent danger.
[0041] See also Figure 5In one embodiment of the utility model, the connecting member 232 is a plurality of through holes 233 provided on the inner nesting 231 and the outer nesting 230. The positions of the through holes 233 on the inner nesting 231 and the outer nesting 230 correspond to each other, and the degree of connection between the cavity 21 and the outside is adjusted by rotating to adjust the overlap of the through holes 233 on the inner nesting 231 and the outer nesting 230. When the cavity 21 is connected to the outside, the first side of the sound outlet 22 is connected to the outside through the cavity 21, the inner nesting 231 and the outer nesting 230 in sequence. The connecting member 232 of this embodiment can continuously adjust the degree of connection between the cavity 21 and the outside by rotating to adjust the overlap of the through holes 233 on the inner nesting 231 and the outer nesting 230, thereby realizing adjustable control of the open effect. The user can select a suitable degree of opening according to environmental needs.
[0042] Furthermore, the inner nesting 231 is disposed in the cavity 21 and connected to the sound outlet 24, and the outer nesting 230 is sleeved on the inner nesting 231 and the outer surface of the sound outlet 24 and connected to the earphone body 10;
[0043] Alternatively, the inner nesting 231 is disposed inside the earphone body 10 and connected to the earphone body 10 , and the outer nesting 230 is sleeved on the inner nesting 231 and the outer surface of the sound outlet 24 .
[0044] In this embodiment, the outer layer nesting 231 is an ellipsoidal structure that matches the concha cavity of the human ear. When the outer layer nesting 231 is inserted into the human ear, the outer edge of the outer layer nesting 231 abuts against the inner wall of the concha cavity of the human ear so that the outer layer nesting 231 is engaged in the concha cavity of the human ear. The outer layer nesting 231 in this embodiment is equivalent to a semi-in-ear, and does not need to be inserted into the ear canal of the human ear, which solves the problem of discomfort caused by the outer layer nesting 231 squeezing the ear canal. Specifically, when the outer layer nesting 231 is inserted into the human ear, the outer edge of the outer layer nesting 231 abuts against the inner wall of the concha cavity of the human ear so that the outer layer nesting 231 is engaged in the concha cavity of the human ear, thereby preventing the outer layer nesting 231 from falling off.
[0045] See also Figure 3-Figure 4In this embodiment, a plurality of sound leakage holes 240 communicating with the cavity 21 are provided on the end surface of the sound outlet portion 24 away from the connecting portion 23, and the plurality of sound leakage holes 240 spread outward from the center of the end surface of the sound outlet portion 24. By providing a plurality of sound leakage holes 240 on the sound outlet portion 24, the sound emitted by the earphone body 10 can be transmitted to the sound outlet 22 through the sound leakage holes 240, and the sound outlet 22 transmits the sound to the human ear; and the external environment sound can be transmitted to the cavity 21 through the through hole 233, and the external environment sound is transmitted to the sound leakage holes 240 through the cavity 21, and the sound leakage holes 240 with a larger radius transmit the external environment sound to the sound outlet 22, and then transmit the sound to the human ear through the sound outlet 22. In some usage scenarios, such as when the user wears the earphones for riding or walking, the user can also hear the external environment sound to prevent danger.
[0046] In this embodiment, the radius of the plurality of sound leakage holes 240 gradually expands from the center of the sound outlet 24 to the outside of the sound outlet 24. Since the outside of the connecting portion 23 is closer to the outside environment, the above design can facilitate the transmission of the sound of the outside environment to the cavity 21 through the through hole 233, and the transmission of the sound of the outside environment to the sound leakage holes 240 through the cavity 21. The sound leakage holes 240 with a larger radius transmit the sound of the outside environment to the sound outlet 22, and then transmit the sound to the human ear through the sound outlet 22. In some usage scenarios, such as when the user wears headphones while riding or walking, the user can also hear the sound of the outside environment to prevent danger.
[0047] Embodiment 2:

When the cavity 21 is connected to the outside world, the first side of the sound outlet 22 is connected to the outside world through the cavity 21, the inner nesting 231 and the outer nesting 230 in sequence; the connecting piece 232 of this embodiment is adjusted by rotating the notches 234 on the inner nesting 231 and the outer nesting 230 The alignment section of the slot 234 can effectively adjust the connected area, and can continuously adjust the connected area between the cavity 21 and the outside world, thereby realizing adjustable control of the open effect. The user can choose the appropriate degree of openness according to environmental needs; and the external environmental sound can be transmitted to the cavity 21 through the slot 234, and the external environmental sound is transmitted to the sound leakage hole 240 through the cavity 21. The sound leakage hole 240 with a larger radius transmits the external environmental sound to the sound outlet 22, and then transmits the sound to the human ear through the sound outlet 22. In certain usage scenarios, such as when the user wears headphones while riding or walking, the user can also hear the external environmental sound to prevent danger.
[0049] Embodiment 3:
[0050] See also Figure 7, this embodiment is basically the same as embodiment 1, except that the connecting piece 232 is a plurality of gaps 235 opened on the inner nesting 231 and the outer nesting 230, and the plurality of gaps 235 on the inner nesting 231 and the outer nesting 230 are staggered. The degree of alignment of the gaps 235 on the inner nesting 231 and the outer nesting 230 is adjusted by rotation, and the degree of connectivity between the cavity 21 and the outside world is adjusted. When the cavity 21 is connected with the outside world, the first side of the sound outlet 22 is connected with the outside world through the cavity 21, the inner nesting 231 and the outer nesting 230 in sequence; the connecting piece 232 of this embodiment is adjusted by rotation between the inner nesting 231 and the outer nesting The degree of alignment of the gap 235 on the nest 230 can effectively adjust the connected area, and can continuously adjust the connected area between the cavity 21 and the outside world, thereby realizing adjustable control of the open effect, and the user can choose the appropriate degree of openness according to environmental needs; and the external environmental sound can be transmitted to the cavity 21 through the gap 235, and the external environmental sound is transmitted to the sound leakage hole 240 through the cavity 21. The sound leakage hole 240 with a larger radius transmits the external environmental sound to the sound outlet 22, and then transmits the sound to the human ear through the sound outlet 22. In certain usage scenarios, such as when the user wears headphones while riding or walking, the user can also hear the external environmental sound to prevent danger.
[0051] It should be noted that in other embodiments of the present invention, the connecting piece 232 can also be a valve-type connecting piece, a shielding-type connecting piece, a mesh-type connecting piece, etc. Designers can also choose a suitable connecting piece according to actual conditions. The above-mentioned valve-type connecting piece, shielding-type connecting piece and mesh-type connecting piece can all be adjusted to achieve the degree of connectivity between the internal cavity 21 and the outside world, thereby achieving adjustable control of the open effect.
