Description

Earphone module and head-mounted device

Technical Field

The invention relates to an earphone module and a head-mounted device.

Background

With the advancement of technology, the conventional flat-type video display device cannot satisfy the general consumers, and instead, has a three-dimensional virtual reality display device. Currently, a head-mounted virtual reality display device is widely used.

Generally, the conventional usage method is to wear the display device on the head of the user by using a strap worn on the head, and the user needs to wear an earphone additionally, so that the user can have visual and auditory effects after the earphone is connected to the display device. However, this separate wearing mode is not good for the user, and not only is the user easily burdened due to its large volume and weight and the interference caused when wearing, but also the connecting line between the two is easily hung around the head of the user after wearing, which causes inconvenience when using.

Therefore, how to further improve the above situation to achieve the purpose of reducing the burden of the user and improving the convenience of use on the premise that the user can obtain the visual and auditory effects synchronously becomes a subject to be considered and solved by the related technical personnel.

Disclosure of Invention

The invention provides an earphone module and a head-mounted device, wherein the earphone module has driving modes in different axial directions and is detachable relative to a head-mounted piece of the head-mounted device, so that the head-mounted device can provide different operation modes for a user.

The earphone module comprises a support, a base piece, a fastener, an elastic piece and an earphone. The bracket is provided with a sliding groove. The base member is rotatably and slidably coupled to the chute. The base member has an abutment portion. The fastener is pivoted to the base piece. The fastener pivots relative to the base piece and the support to switch between a first state and a second state. The elastic sheet is arranged on the fastener, and part of the elastic sheet is positioned on the moving path of the abutting part. When the elastic piece is in the first state, the abutting part keeps a distance with the elastic piece, and when the elastic piece is in the second state, the abutting part is abutted between the elastic piece and the fastener. The earphone is arranged on the bracket.

The head-wearing device comprises a head-wearing piece and an earphone module. The earphone module is detachably assembled on the head-wearing piece. The earphone module comprises a support, a base piece, a fastener, an elastic piece and an earphone. The bracket is provided with a sliding groove. The base member is rotatably and slidably coupled to the chute. The base member has an abutment portion. The fastener is pivoted to the base piece. The fastener pivots relative to the base piece and the support to switch between a first state and a second state. The fastener is used for detachably fastening the head-wearing piece. The elastic sheet is arranged on the fastener, and part of the elastic sheet is positioned on the moving path of the abutting part. When the elastic piece is in the first state, the abutting part keeps a distance with the elastic piece, and when the elastic piece is in the second state, the abutting part is abutted between the elastic piece and the fastener. The earphone is arranged on the bracket.

Based on the above, the earphone module is rotatably and slidably coupled to the chute of the bracket through the base member, and the fastener is pivotally connected to the base member, so that a multi-axial driving mode exists between the fastener and the bracket, and therefore, for the earphone configured on the bracket, once the fastener is fastened to a specific object, such as a headset, a user wearing the headset can drive the earphone in the multi-axial direction, so that the earphone fits the contour of the head and face of the user and fits the ear, thereby improving the convenience and comfort of the user in operating the headset.

Detailed Description

Fig. 1 is a schematic view of a head-mounted device according to an embodiment of the invention. Fig. 2 shows the headgear of fig. 1 from another perspective. Fig. 3 is a schematic view of the headgear of fig. 1 in a simple, detachable manner. Referring to fig. 1 to fig. 3, in the present embodiment, the headset 10 includes an earphone module 100, a headset 200 and a display 300, wherein the headset 200 is suitable for being worn on a head (not shown) of a user, the display 300 is disposed on the headset 200 and located on a front side of the user, and the earphone module 100 is detachably assembled on the headset 200 and located on a left side and a right side of the user, so that the headset 10 becomes the head-mounted display.

In the embodiment, the earphone module 100 includes

earphone elements

110A and 110B with different sound channels, a connection wire 120A for electrically connecting the

earphone elements

110A and 110B, and a connection wire 120B for electrically connecting the earphone module 100 and the display 300, so as to provide visual images and surround sound effects for a user at the same time. The purpose of the head-mounted device is not limited, and in other embodiments not shown, the display 300 can be replaced by other devices according to situations or needs, such as a personal illumination lamp, or a head-mounted device embedded in a helmet.

Because the earphone module 100 can be quickly assembled and disassembled on the head-wearing part 200 according to the requirement of the user, the manufacturing cost required by the existing locking or integrated structure can be saved, namely, the earphone module 100 is mounted on the head-wearing part 200 when the hearing requirement of the user exists, and the head-wearing device 10 is not limited to a fixed structure, thereby improving the flexibility of matching.

Fig. 4 is an exploded view of the earphone module of fig. 1. Referring to fig. 4, it should be noted that the

headphone elements

110A and 110B belonging to different channels have substantially the same structure, and therefore the headphone element 110A of one channel is used as a description target, and the headphone element 110B of the other channel has the same components and is not repeated. Of course, in another embodiment not shown, the earphone module 100 may also be provided with only the earphone component 110A or only the earphone component 110B.

In the present embodiment, the earphone assembly 110A includes a support 111, a base 112, a fastener 113, a spring 114, and an earphone 115. The bracket 111 has a slide groove 111 a. The base member 112 is rotatably and slidably coupled to the sliding groove 111 a. The base piece 112 has an abutment B11. The fastener 113 is pivotally connected to the base 112. The fastener 113 is pivoted relative to the base 112 and the bracket 111 to switch between a first state and a 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 contact portion B11 is spaced from the spring plate 114, and in the second state, the contact portion B11 is in contact with the spring plate 114 and the hook 113. The earphone 115 is disposed on the holder 111. Referring to fig. 3 and 4, the base member 112 slides in the sliding slot 111a along the first axis X1, the base member 112 rotates relative to the bracket 111 along the second axis X2, and the fastener 113 pivots relative to the base member 112 and the bracket 111 along the third axis X3, wherein the second axis X2 is orthogonal to the third axis X3.

Fig. 5A and 5B show partial component diagrams of the headphone module from different perspectives. Referring to fig. 4, fig. 5A and fig. 5B, in detail, the support 111 is assembled by components a1 and a2, and the earphone 115 is disposed on the component a 2. The base member 112 is composed of a rotating disc B1, a structural member B2, a ring spring B3, a nut B4, a screw B5, a pivot B6 and a torsion spring B7, wherein the screw B5 is locked to the nut B4, and passes through a rotating disc B1, a structural member B2 and a ring spring B3, so that the rotating disc B1 and the structural member B2 are clamped on lip structures at two sides of the sliding slot 111a, thereby achieving the effect of enabling the base member 112 to slide back and forth along the sliding slot 111 a. The ring spring B3 provides a damping effect for the related members clamped by the screw B5 and the nut B4, and is used to adjust the clamping force between the screw B5 and the nut B4, so that the rotating disc B1 can slide along the sliding slot 111a and can also rotate around the second axis X2.

The pivot B6 is used as a rotating disc B1 connecting the fastening member 113 and the base member 112, so that the fastening member 113 can pivot relative to the base member 112 and the bracket 111 by a third axis X3, wherein the torsion spring B7 is sleeved on the pivot B6 and abuts between the base member 112 and the fastening member 113. Further, 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 constantly drives the fastener 113 to switch to the first state relative to the base member 112, which will be further described later. Referring to fig. 5A and 5B, the base member 112 further has a limiting post B12 extending from the turntable B1 and extending to the sliding slot 111a, and when the turntable B1 of the base member 112 rotates relative to the bracket 111 about the second axis X2, the limiting post B12 abuts against and stops the side wall 111B of the sliding slot 111a, so as to limit the rotation range of the base member 112.

Referring to fig. 4, fig. 5A and fig. 5B, two opposite ends of the fastening member 113 respectively have a first fastening portion 113c, at least one first limiting portion 113e and a first abutting portion 113d, wherein the first limiting portion 113e is located at the first fastening portion 113c, and the first fastening portion 113c and the first abutting portion 113d extend in opposite directions. Correspondingly, the head-wearing piece 200 has a pair of second buckling parts 210 and at least one second limiting part 211, and the first buckling part 113c and the second buckling part 210 are buckled correspondingly, and the second limiting part 211 is clamped in the first limiting part 113e, so that the buckle 113 can be buckled and positioned on the head-wearing piece 200 simply, smoothly and quickly. It should be noted that the fastening portions are disposed corresponding to the recessed structure and the protruding structure, and the limiting portion is also disposed corresponding to the recessed structure and the protruding structure.

As can be seen from the above, the fastening member 113 includes the first fastening portion 113c and the first limiting portion 113e, so that the earphone module 100 can be conveniently and quickly assembled to the headset 200. Conversely, when the earphone module 100 is to be detached from the head-wearing part 200, the first pushing portion 113d is only required to apply a force to pull the fastening member 113, so that the first fastening portion 113c and the first position-limiting portion 113e are smoothly separated from the second fastening portion 210 and the second position-limiting portion 211, and the earphone module 100 is easily detached from the head-wearing part 200.

Fig. 6A and 6B illustrate different modes of operation of the earphone module on the headset. Fig. 7A to 7C are partial sectional views showing the headphone module in different states. Please refer to fig. 5A, fig. 6A and fig. 7A, at this time, the earphone module 100 is in the first state of moving inward. The clip 113 of the present embodiment is a C-shaped clip, which has a recess R1 and opposite ends 113a and 113b, the elastic piece 114 spans the recess R1 of the C-shaped clip and is fixed to the opposite ends of the C-shaped clip, that is, the insertion grooves 113f at the

structural bodies

113a and 113b, 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 112, the abutting portion B11 is a protruding structure inserted through the rotary disk B1 and extends through the opening R2 into the recess R1 toward the resilient piece 114. That is, the abutting portion B11 is located between the pivot B6 and the resilient tab 114 of the catch 113 having a C-shaped profile from a side view.

Further, in the first state shown in fig. 7A, the abutting portion B11 is still at a relative distance from the first segment S1 of the resilient tab 114. Then, the user starts to pull the bracket 111 to switch from fig. 7A to fig. 7B, the abutting portion B11 abuts against the second section S2 of the elastic piece 114, and when the user continues to apply force, the abutting portion B11 can be driven to deform the elastic piece 114 (as shown by the dotted 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 fig. 7C and fig. 6B, the elastic force generated by the deformation of the elastic piece 114 can drive the abutting portion B11 to move to the third section S3 of the elastic piece 114, and the abutting portion B11 is abutted between the elastic piece 114 and the buckle 113, so that the earphone module 100 is in the second state shown in fig. 6B and moved outward.

Fig. 7C further shows the corresponding relationship between the elastic piece 114 and the contour of 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 limit profile on the moving path of the abutting portion B11, and in the process of switching the fastener 113 from the first state to the second state (from fig. 7A to fig. 7C), the limit profile is tapered (in the direction from top to bottom in fig. 7C), so when the user provides a force to make the abutting portion B11 overcome the resistance of the elastic piece 114 and deform it, the force is released, the abutting portion B11 is driven by the elastic piece 114 to switch to the second state, and the abutting portion B11 is limited between the elastic piece 114 and the limit groove of the fastener 113.

On the contrary, when the earphone module 100 is to be switched from the second state shown in fig. 7C to the first state shown in fig. 7A, the user also needs to apply a force to drive the abutting portion B11 to deform the elastic piece 114, and as mentioned above, the torsion spring B7 constantly drives the fastener 113 to switch to the first state relative to the base element 112, so that the abutting portion B11 moves to the second section S2 and overcomes the resistance of the elastic piece 114, and then the user can release the force, and the torque of the torsion spring B7 provides the requirement to reset the abutting portion B11 to the corresponding first section S1.

It should be noted that, besides providing the user with a feeling of operation, the deformation of the elastic sheet 114 can also serve to inform the user of the sound generated by the deformation of the elastic sheet 114.

Fig. 8 is a schematic view of the headset of fig. 2 in another mode of operation. Referring to fig. 2 and 8, the earphone module 100 is rotated by the turntable B1 (shown in fig. 4) about the second axis X2 to achieve different operation modes. In this state, since the wire 120A has the winding structures L1 and L2, the wire 120A has a flexible characteristic, thereby providing a margin required for adjustment.

In summary, in the above embodiments of the invention, the earphone module is rotatably and slidably coupled to the chute of the bracket through the base member, and the fastener is pivotally connected to the base member, so that there is a multi-axial driving mode between the fastener and the bracket, and therefore, for the earphone configured on the bracket, once the fastener is fastened to a specific object, such as a headset of a head-mounted device, a user wearing the headset can drive the earphone in the multi-axial direction to conform to the contours of the head and the face of the user and attach to the ear, thereby improving convenience and comfort of the user in operating the head-mounted device.

Furthermore, for the fastener and the bracket, because the abutting part of the base element, the elastic sheet and the recess of the fastener are matched with each other, on the moving path of the abutting part, the elastic sheet and the recess of the fastener form a limit outline to the abutting part, so that a user needs to continuously apply force to overcome the resistance of the elastic sheet to the abutting part, the moving process of the abutting part can enable the fastener to generate obvious mode switching relative to the base element, and better operation feeling is provided for the user.

Although the present invention has been described with reference to the above embodiments, it should be understood that various changes and modifications can be made therein by those skilled in the art without departing from the spirit and scope of the invention.
