detailed description

In an embodiment, as shown in FIGS. 1-5B, the braided earphone 5 includes a braid 1, an elastic band 3, an earphone 2, and a wire 4. The woven belt 1 and the elastic belt 3 extend in the same direction, and the woven belt 1 penetrates the elastic belt 3 along the extending direction of the elastic belt 3 (that is, the elastic belt 3 is sleeved outside the woven belt 1, refer to FIG. 5A); The first end is fixed on the braid 1 , and the second end of the elastic band 3 is slidably connected to the braid 1 along the extending direction of the braid 1; the second end of the elastic strip 3 is connected to the earphone 2, and the earphone 2 is along the braid 1 The extending direction is slidably connected with the braid 1; the elastic band 3 and the braid 1 form a receiving cavity, and the wire 4 is disposed in the receiving cavity; the first end of the wire 4 is fixedly connected with the first end of the elastic band 3, and the wire 4 The second end is connected to the earphone 2 through the second end of the elastic band 3. In another embodiment, referring to FIG. 5B, the elastic band 3 may not be sleeved outside the woven belt 1, that is, except that the first end of the elastic band 3 is fixed on the woven tape 1, the remaining portion of the elastic band 3 is woven. The extending direction of the belt 1 is provided separately from the braid 1 , the second end of the elastic band 3 is connected to the earphone 2, the wire 4 is disposed in the elastic band 3, and the other structure in Fig. 5B is the same as that in Fig. 5A.

In the initial state, the elastic band 3 is in a natural state, the distance between the earphone 2 and the first end of the elastic band 3 is small, and the wire 4 is wavyly accommodated in the accommodating cavity or in the elastic band 3. When the user adjusts the position of the earphone 2, and the earphone 2 is moved along the extending direction of the braided belt 1 to move the earphone 2 away from the first end of the elastic band 3, the elastic band 3 is in a stretched state, in the receiving cavity or in the elastic band 3. The wire 4 is partially or completely straightened. When the user adjusts the position of the earphone 2 again, the earphone 2 is moved along the extending direction of the braid 1 to bring the earphone 2 closer to the first end of the elastic band 3, the stretched length of the elastic band 3 is reduced, and the receiving cavity or the elastic band 3 is The straightened wire 4 in the middle is restored to a wave shape. The elastic band 3 can always remain parallel to the braid 1 during the entire use, and does not undergo deformation perpendicular to the direction of the braid 1, so that under the action of the elastic band 3, the wire 4 will be in the receiving cavity or the elastic band 3. The middle is bent parallel to the direction of the braid 1 without being bent in a direction perpendicular to the braid 1 (the direction perpendicular to the braid 1 is the position where the cheeks are located), thereby ensuring user comfort.

Alternatively, the maximum length of the elastic band 3 is less than or equal to the length of the wire 4. Setting the maximum length of the elastic band 3 to be less than or equal to the length of the wire 4 prevents the wire 4 from being torn.

Optionally, the earphone 2 is a bone conduction earphone. The conductive side 201 of the bone conduction earphone is located on the same side of the braid 1 with the wire 4. The bone conduction earphone 2 has better conduction effect and is more suitable for use in sports. In other embodiments, the earphone 2 is optionally an in-ear or over-the-ear earphone 2.

Optionally, the inside of the earphone 2 is provided with a groove 202, the notch of the groove 202 is opposite to the braid 1, and the groove bottom of the groove 202 is parallel with the braid 1. Optionally, a groove bottom of the groove 202 is disposed near a side of the braid 1 with a spring 204 having an axis perpendicular to the braid 1 , and a pressing piece 203 is disposed between the spring 204 and the braid 1 .

Alternatively, the pressing piece 203 is provided with a protrusion 2031 near one side of the braided belt 1. Under the elastic force of the spring 204, the pressing piece 203 presses the woven tape 1, and when the static friction force generated between the woven tape 1 and the pressing piece 203 is greater than the tensile force generated by the elastic band 3, the earphone 2 can be fixed to the woven tape 1. Anywhere. When it is necessary to adjust the position of the earphone 2, the earphone 2 is manually dialed to overcome the static friction between the pressing piece 203 and the braid 1 to cause the earphone 2 to slide relative to the braid 1; then, between the pressing piece 203 and the braid 1 The sliding friction causes the earphone 2 to be relatively displaced from the braid 1. After the hand is released, the earphone 2 is fixed in the manually adjusted position due to the static friction. By providing the protrusions 2031, the contact area of the braid 1 and the sheet 203 can be reduced, the sliding friction can be reduced, and the work performed to overcome the sliding friction when adjusting the position of the headphone 2 can be reduced. In other embodiments, it is also possible to provide only the pressing piece 203 without providing the spring 204, and the above effect can also be achieved by the friction between the protrusion 2031 and the woven tape 1.

Optionally, the middle portion of the braided belt 1 is provided with a partitioning groove 101, which separates the braided belt 1 into a first belt 102 and a second belt 103; the earphone 2 is provided with a first hole 21 and a second hole 22, first A partition block 23 is disposed between the hole 21 and the second hole 22; the first belt 102 penetrates the first hole 21, the second belt 103 penetrates the second hole 22, and the partition block 23 is disposed in the partition groove 101. This arrangement makes the sliding between the earphone 2 and the braid 1 more stable and reliable. In other embodiments, the partitioning groove 101 may not be provided in the middle of the braided belt 1 and the partitioning block 23 may not be provided in the earphone 2, so that the complete braided belt 1 may penetrate the earphone 2 and the earphone 2 may be slid along the braided belt 1.

During the processing, the braided belt 1 may be first spliced into a predetermined length, the elastic fabric is sewn into an elastic band 3 having openings at both ends, and then the elastic band 3 is placed on the woven tape 1. The wire 4 is placed in the interlayer (ie, the accommodating cavity) of the woven tape 1 and the elastic band 3 or in the elastic band 3, and the first end of the elastic band 3 is fixed together with the woven tape 1, the second end of the elastic band 3 and the earphone 2 connection.

In one embodiment, a smart helmet is provided, including a helmet body 6 and any of the above-mentioned braided earphones 5. The inside of the helmet body 6 is provided with a control unit 61, and the braided earphone 5 is disposed on the side of the helmet body 6 (for example, the side surface) Below), the first end of the wire 4 is electrically connected to the control unit 61.

The “first” and “second” in this article are only for the purpose of distinguishing between descriptions, and there is no special meaning.
