Of course, in another unillustrated embodiment, the earphone module 100 may also only have the earphone component 110A or only the earphone component 110B.

In this embodiment, the earphone assembly 110A includes a bracket 111, a base 112, a fastener 113, an elastic sheet 114 and an earphone 115. The bracket 111 has a sliding groove 111a. The base 112 is rotatably and slidably coupled to the sliding groove 111a. The base 112 has a contact portion B11. The fastener 113 is pivotally connected to the base 112. The fastener 113 pivots relative to the base 112 and the bracket 111 to switch between the first state and the second state. The elastic piece 114 is disposed on the fastener 113, and a part of the elastic piece 114 is located on the moving path of the abutting portion B11. In the first state, the abutting portion B11 keeps a distance from the elastic piece 114, and in the second state, the abutting portion B11 is abutted between the elastic piece 114 and the fastener 113. The earphone 115 is arranged on the stand 111. 3 and 4 at the same time, the base 112 slides along the first axis X1 in the sliding groove 111a, the base 112 rotates with respect to the bracket 111 along the second axis X2, and the fastener 113 is relative to the base along the third axis X3 112 pivots with the bracket 111, and the second axis X2 and the third axis X3 are orthogonal to each other.

5A and 5B show schematic diagrams of parts of the earphone module from different perspectives. Please refer to FIG. 4, FIG. 5A, and FIG. 5B at the same time. In detail, the bracket 111 is assembled from the parts A1 and A2, and the earphone 115 is disposed on the part A2. The base member 112 is composed of a turntable B1, a structural member B2, a ring spring B3, a nut B4, a screw B5, a pivot B6, and a torsion spring B7. The screw B5 is locked to the nut B4 and passes through the turntable B1. The structural member B2 and the ring spring B3 make the turntable B1 and the structural member B2 clamp the lip structures on both sides of the sliding groove 111a, so as to achieve the effect of allowing the base member 112 to slide back and forth along the sliding groove 111a. The ring spring B3 provides a shock-absorbing effect for the related components locked and clamped by the screw B5 and the nut B4, and is used to adjust the locking force between the screw B5 and the nut B4, so that the turntable B1 slides along While the groove 111a slides, it can also have the effect of rotating about the axis X2.

The pivot B6 is used as the turntable B1 connecting the fastener 113 and the base 112, so that the fastener 113 can pivot relative to the base 112 and the bracket 111 by the third axis X3, wherein the torsion spring B7 is sleeved on the pivot B6 And it abuts between the base 112 and the fastener 113. Furthermore, the end B71 of the torsion spring B7 abuts against the groove B13 of the turntable B1, and the other end B72 of the torsion spring B7 abuts against the opening R2 of the fastener 113. Here, the torsion spring B7 constant drive fastener 113 is switched to the first state relative to the base 112, which will be further described later. Please refer to FIGS. 5A and 5B again. The base 112 also has a limit post B12 extending from the turntable B1 and extends to the sliding groove 111a. When the turntable B1 of the base 112 rotates with respect to the bracket 111 on the second axis X2 During the process, the limiting column B12 and the side wall 111b of the sliding groove 111a abut against each other to stop, thereby limiting the rotation range of the base 112.

4, 5A and 5B, opposite ends of the fastener 113 each have a first locking portion 113c, at least one first limiting portion 113e and a first pushing portion 113d, wherein the first limiting portion 113e is located at the first buckling portion 113c, and the first buckling portion 113c and the first pushing portion 113d extend opposite to each other. Correspondingly, the headwear 200 has a pair of second buckling portions 210 and at least one second limiting portion 211. By correspondingly buckling the first buckling portion 113c and the second buckling portion 210, the second The limiting portion 211 is clamped on the first limiting portion 113e, so that the fastener 113 can be buckled and positioned on the headwear 200 simply, smoothly and quickly. It should be noted that the buckling portions are correspondingly provided with a concave structure and a protruding structure, and the limiting portion is also provided with a corresponding recessed structure and a protruding structure.

It can be seen from the above that the earphone module 100 can be easily and quickly assembled to the headset 200 because the fastener 113 has the first fastening portion 113c and the first limiting portion 113e. Conversely, when the earphone module 100 is to be detached from the headwear 200, only the force is applied to the first pushing portion 113d to use the elasticity of the fastener 113 to pull the fastener 113, so that the first fastener The holding portion 113c and the first limiting portion 113e are smoothly separated from the second holding portion 210 and the second limiting portion 211, and the earphone module 100 can be easily removed from the headset 200.

6A and 6B illustrate different operation modes of the earphone module on the headset. 7A to 7C show partial cross-sectional views of the earphone module in different states. Please refer to FIG. 5A, FIG. 6A and FIG. 7A first. At this time, the earphone module 100 is in the first state of moving inward. The fastener 113 in this embodiment is a C-shaped fastener, which has a recess R1 and opposite ends 113a, 113b. The elastic piece 114 spans the recess R1 of the C-shaped fastener and is fixed to the opposite ends of the C-shaped fastener, that is, The embedding grooves 113f at the structural bodies 113a and 113b are shown, and the distance between one end of the elastic piece 114 and the recess R1 is greater than the distance between the other end of the elastic piece 114 and the recess R1. For the base member 112, the abutting portion B11 is essentially a protruding structure in which the plug penetrates the turntable B1, and extends through the opening R2 into the recess R1 and faces the elastic piece 114. That is, when viewing the fastener 113 with a C-shaped profile from a side view, the abutting portion B11 is located between the pivot B6 and the elastic piece 114.

Furthermore, in the first state as shown in FIG. 7A, at this time, the abutting portion B11 and the first section S1 of the elastic piece 114 still maintain a relative distance. Then, the user starts to pull the bracket 111 to transform it from the state shown in FIG. 7A to FIG. 7B. At this time, the abutting portion B11 abuts on the second section S2 of the elastic piece 114. When the user continues to apply force, it can drive The abutting portion B11 deforms the elastic piece 114 (as shown by the dashed line), that is, the elastic piece 114 is deformed at the second section S2. Finally, when the user releases the force, as shown in the second state shown in FIGS. 7C and 6B, the elastic force generated by the deformation of the elastic piece 114 can drive the abutment portion B11 to move to the third section S3 of the elastic piece 114, and let The abutting portion B11 is abutted between the elastic piece 114 and the fastener 113, so that the earphone module 100 is in the second state of moving outward as shown in FIG. 6B.

FIG. 7C further illustrates the corresponding relationship between the contours of the elastic piece 114 and the fastener 113 in a side view. As shown in FIG. 7C, the elastic piece 114 and the bottom of the recess R1 form a limiting contour on the movement path of the abutting portion B11, and the fastener 113 is switched from the first state to the second state (from FIGS. 7A to 7C) , The limit profile is tapered (from top to bottom in Figure 7C), so when the user provides a force to make the abutment portion B11 overcome the resistance of the elastic piece 114 and deform it, the force is released to abut The piece B11 is driven by the elastic piece 114 to switch to the second state, and the abutting portion B11 will be restricted between the elastic piece 114 and the limiting groove of the fastener 113.

Conversely, when the earphone module 100 is to be switched from the second state in FIG. 7C back to the first state in FIG. 7A, the user also needs to force the deforming elastic piece 114 of the contact portion B11 first, and as mentioned above, the torsion spring B7 The constant drive fastener 113 is switched to the first state with respect to the base 112, so the abutment portion B11 moves to the second section S2 and overcomes the resistance of the elastic piece 114, the user can release the force, which is followed by the torsion force of the torsion spring B7 Provide the need to reset the abutting portion B11 to the corresponding first segment S1.

It should also be noted that the deformation of the elastic sheet 114 not only provides the user's operating feel, but the sound generated by the deformation of the elastic sheet 114 can also be used to inform the user.

FIG. 8 is a schematic diagram of the head-mounted device of FIG. 2 in another operation mode. Please refer to FIG. 2 and FIG. 8 at the same time. At this time, the earphone module 100 has different operation modes caused by rotating the turntable B1 (shown in FIG. 4) on the second axis X2. In this state, since the wire 120A has the winding structure L1 and L2, the wire 120A has a retractable characteristic, which can provide a margin required for adjustment.

In summary, in the above-mentioned embodiments of the present invention, the earphone module is rotatably and slidably coupled to the sliding groove of the bracket through the base member, and the fastener is pivotally connected to the base member, thereby causing the fastener and There is a multi-axial drive mode between the brackets. Therefore, for the headset configured on the bracket, once the fastener is fastened to a specific object, such as the headset of a headset, the user wearing the headset is The earphone can be driven in a multi-axial manner to conform to the contours of the user's head and face and conform to the ears, thereby improving the convenience and comfort of the user in operating the headset.

Furthermore, for the fastener and the bracket, since the abutment portion of the base member, the elastic piece and the recess of the fastener are matched with each other, the movement path of the abutment portion, the recess of the elastic piece and the fastener forms the opposite of the abutment portion. The limit profile allows the user to continue to apply force to overcome the resistance caused by the elastic piece to the abutting part, so that the movement of the abutting part can make the fastener switch obvious mode relative to the base part, and then to the user Provide a better sense of operation.

Although the present invention has been disclosed in the above embodiments, it is not intended to limit the present invention. Anyone with ordinary knowledge in the technical field can make some changes and modifications without departing from the spirit and scope of the present invention. The scope of protection of the present invention shall be determined by the scope of the attached patent application.
