DETAILED DESCRIPTION OF EMBODIMENTS

The following will provide, in conjunction with the accompanying drawings and the embodiments of the present disclosure, detailed description of the present disclosure.

As shown in FIGS. 1 to 4, the present disclosure provides a wearable device, including: a casing 1 having an accommodating cavity 11, a feedback module 2 and a moveable part 3 both arranged in the accommodating cavity 11. The casing 1 includes an opening 12, one end of the moveable part 3 is connected to the feedback module 2 through the opening 12, and an other end of the moveable part contacts with a wearer. The feedback module 2 includes a speaker 21 and a vibration component 22. The vibration component 22 vibrates in a direction directing from the accommodating cavity 11 towards the opening 12, and the moveable part 3 is fixedly connected to the vibration component 22, such that the moveable part 3 is also able to vibrate along a height direction of the feedback module 2.

The wearable device may be electronic devices such as AR devices or VR devices. Taking AR glasses as an example, feedback module 2 may be arranged in the legs of AR glasses and arranged to contact with the wearer's skin, to allow the wearer to feel the vibration of the moveable part 3. The feedback module 2 includes a speaker 21, and the wearable device may warn the wearer using the sound emitted by the speaker 21. The feedback module 2 further includes a vibration component 22 configured to drive the moveable part 3 to vibrate, thereby warning the wearer through tactile sense. In this way, the user experience of the wearer can be improved.

As shown in FIGS. 2 and 4, in some embodiments, the casing 1 includes at least one guide groove 13, the at least one guide groove 13 and the opening 12 are defined on a same side of the casing 1, and the at least one guide groove 13 extends along the direction directing from the opening 12 towards the accommodating cavity 11. The moveable part 3 includes at least one protrusion 31 formed on a side of the moveable part facing towards the feedback module, and each protrusion of the at least one protrusion 31 is able to move into and move along a respective guide groove of the at least one guide groove 13.

With the cooperation of the at least one guide groove 13 and the at least one protrusion 31, the movement directions of the moveable part 3 during vibration of the moveable part relative to the casing 1 can be limited. In this way, the possibility that the moveable part 3 moves relative to the casing 1 along other directions can be reduced, and the stability of the wearable device can be improved.

As shown in FIG. 2, in some embodiments, the cross-section of each guide groove 13 may be X-shaped, rectangular, or other shapes except for a circular shape. The cross-section of each protrusion 31 corresponds to the cross-section of a respective guide groove 13. When a protrusion 31 moves into a respective guide groove 13, the relative position of the casing 1 to the moveable part 3 can be limited, thereby reducing the possibility that the moveable part 3 rotates relative to the casing 1.

As shown in FIGS. 2 and 4, in some embodiments, the casing 1 includes, on a side of the casing, at least two guide grooves 13 defined at intervals and surrounding the opening 12. The moveable part 3 includes at least two protrusions 31, and each protrusion of the at least two protrusions 31 is arranged to correspond to a respective guide groove of the at least two guide grooves 13.

By providing a plurality of guide grooves 13 and a plurality of protrusions 31, the relative position of the moveable part 3 to the casing 1 can be limited, and the possibility that the moveable part 3 rotates relative to the casing 1 can be reduced, thereby limiting the relative position of the moveable part 3 to the vibration component 22, and reducing the possibility that the moveable part 3 detaches from the vibration component 22 due to shaking. In this way, the reliability of the wearable device can be improved.

As shown in FIGS. 2 and 4, in some embodiments, a contact part 4 is arranged on a surface of the moveable part 3 away from the vibration component 22, and the contact part 4 is made of a skin friendly material. The moveable part 3 contacts with the wearer through the contact part 4.

In order to warn the wearer when the moveable part 3 vibrates, it is necessary for the moveable part 3 to come into contact with the wearer's skin. By arranging the contact part 4 made of a skin friendly material on the outer surface of the moveable part 3, the wearer's comfort when wearing the wearable device can be improved.

As shown in FIGS. 5 to 8, in some embodiments, the casing includes a cover plate 14 arranged on a side of the casing contacting with the wearer. The opening 12 is defined on the cover plate 14. The moveable part 3 is made of a skin friendly material. One end of the moveable part 3 is connected to the vibration component 22, and the other end of the moveable part passes through the opening 12 and comes into contact with the wearer's skin. The side wall of the opening 12 can limit the vibration directions of the moveable part 3, thereby improving the stability of the moveable part 3 during vibration.

As shown in FIGS. 9 and 10, in some embodiments, the feedback module 2 includes a mounting bracket 23 and a magnetic circuit system 24.

The magnetic circuit system 24 includes a first magnet 241, a second magnet 242, a third magnet 243, a fourth magnet 244, a first pole shank 245, and a second pole shank 246. The first pole shank 245, the first magnet 241, the second magnet 242, and the second pole shank 246 are sequentially arranged along the thickness direction of the feedback module 2. The third magnet 243 is arranged to surround the first pole shank 245 and the first magnet 241, and there is a first magnetic gap 247 between the third magnet and the first magnet 241. The vibration component 22 includes a vibration coil 221 arranged in the first magnetic gap 247 and able to move in the first magnetic gap 247. In this way, the vibration coil 221, as a vibrator of the vibration component 22, drives the moveable part 3 to vibrate along the height direction of the feedback module 2. The fourth magnet 244 is arranged to surround the second magnet 242 and the second pole shank 246, and there is a second magnetic gap 248 between the fourth magnet and the second magnet 242. The speaker 21 includes a voice coil 211 arranged in the second magnetic gap 248 and able to move in the second gap to cause the speaker 21 to sound.

The speaker 21 and the vibration component 22 are arranged on either sides of the magnetic circuit system 24 and share a same magnetic circuit system 24. In this way, space utilization can be improved, and the space occupied by the feedback module 2 can be reduced, which is conducive to the miniaturization of the wearable device.

As shown in FIGS. 9 and 10, in some embodiments, the vibration component 22 includes a first elastic member 222 which may be a spring plate. An outer end of the first elastic member 222 is connected to the mounting bracket 23, and an inner end of the first elastic member is connected to the vibration coil 221. The first elastic member 222 can deform in response to the movement of the vibration coil 221. The moveable part 3 is connected to the end of the first elastic member 222 away from the vibration coil 221 and vibrates in response to the deformation of the first elastic member 222.

By connecting the first elastic member 222 with the vibration coil 221, the possibility of shaking of the vibration coil relative to the mounting bracket 23 during movement of the vibration coil 221 can be reduced, the stability of the vibration coil 221 during movement can be improved, and thereby improving the stability of the moveable part 3 during vibration, which is conducive to improvement of the comfort of the wearer.

As shown in FIGS. 11 and 12, in some embodiments, the vibration component 22 includes a support member 223, a main body 223a of the support member 223 is configured as an annulus and is connected to the vibration coil 221. The moveable part 3 is connected to the end of the main body 223a away from the vibration coil 221. Fixing parts 223b are arranged on inner side and outer side of the main body 223a. One respective fixing part of the fixing parts 223b arranged on the inner side of the main body 223a is connected to the first pole shank 245, and one respective fixing part of the fixing parts 223b arranged on the outer side of the main body 223a is connected to the mounting bracket 23. The main body 223a can deform in response to movement of the vibration coil 221, and therefore can actuate the moveable part 3 to move.

The main body 223a can deform in response to movement of the vibration coil 221, thereby limiting moving directions of the vibration coil 221 in the first magnetic gap 247, and reducing the possibility of shaking of the vibration coil 221 in other directions during movement of the vibration coil. In this way, the stability of the vibration coil 221 and the moveable part 3 during vibration can be improved, which is conducive to improvement of comfort of the wearer.

As shown in FIGS. 13 to 15, in some embodiments, in the length direction of the feedback module 2, the speaker 21 and the vibration component 22 are juxtaposed. The vibration component 22 includes a mass block 224 and a drive coil 225 sleeved on the mass block 224. A magnetic part 226 is arranged along a circumference of the drive coil 225, and there is a gap between the magnetic part 226 and the drive coil 225, to enable the drive coil 225 to move relative to the magnetic part 226.

The mass block 224 is a H-shaped structural member, and the drive coil 225 is arranged in the middle of the mass block 224, enabling the drive coil 225 to move the mass block 224 along the height direction of the feedback module 2. By juxtaposing the speaker 21 and the vibration component 22, the speaker 21 and the vibration component 22 use different magnetic circuits. In this way, the possibility of interaction between the speaker 21 and the vibration component 22 can be reduced, which is conducive to improvement of the reliability of the feedback component.

As shown in FIGS. 14 and 15, in some embodiments, the vibration component 22 further includes a connecting part 227. One end of the connecting part 227 is connected to the moveable part 3, and an other end of the connecting part is connected to the mass block 224, to enable the mass block 224 to drive the moveable part 3 to move.

As shown in FIGS. 14 and 15, in some embodiments, the vibration component 22 further includes a second elastic member 228 which may be also a spring plate. An inner end of the second elastic member 228 is connected to the mass block 224, and an outer end of the second elastic member is connected to the magnetic part 226. The second elastic member 228 can deform in response to movement of the mass block 224.

The second elastic member 228 may be connected to the magnetic part 226 by a spacer block 229, to provide a space for arranging the mass block 224 between the second elastic member 228 and the magnetic part 226. When no current is applied in the drive coil 225, the second elastic member 228 can limit the position of the mass block 224, so that the mass block 224 and the drive coil 225 align with the magnetic part 226. When current is applied in the drive coil 225, the second elastic member 228 can limit the moving direction of the mass block 224, thereby improving the stability of the mass block 224 during movement.

The above mentioned are only the embodiments of the present disclosure. It should be pointed out that for those skilled in the art, improvements can be made without departing from the inventive concept of the present disclosure, but these improvements are all within the scope of protection of the present disclosure.
