Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0028] Embodiment one

[0029] In combination with FIGS. 1 to 7, the embodiment of the present application provides a smart wear glasses leg 1000, which comprises a shell 100 having a containing space 101 and a sound emitting unit 3 contained in the containing space 101, and the shell 100 is further provided with a sound outlet 11 penetrating therethrough, which communicates the containing space 101 with the outside. The sound waves emitted by the sound emitting unit 3 are transmitted to the outside through the sound outlet 11.

[0030] The shell 100 comprises an upper cover 1 and a lower cover 2 which cooperatively form the containing space 101, wherein the upper cover 1 is provided with a support wall 12 located in the containing space 101 and in a ring shape, the sound emitting unit 3 is fixed to the support wall 12, and the sound outlet 11 is arranged on the upper cover 1.

[0031] Specifically, the sound emitting unit 3 comprises a basin frame 31 fixedly supported on the support wall 12, a vibration system 32 and a magnetic circuit system 33 respectively fixed to the basin frame 31 and driving the vibration system 32 to vibrate. The support wall 12 extends from the upper cover 1 to the lower cover 2, and when the sound emitting unit 3 is fixed to the support wall 12, the magnetic circuit system 33 is farther away from the upper cover 1 than the vibration system 32.

[0032] The vibration system 32 comprises a diaphragm 321 fixed between the basket 31 and the support wall 12, and a voice coil 322 fixed to the diaphragm 321 near the side of the magnetic circuit system 33 and driving the diaphragm 321 to vibrate. In the embodiment, the edge of the diaphragm 321 is fixed to the basket 31, and the diaphragm 321 divides the receiving space into the front sound cavity 10 and the rear cavity 30 which are independent of each other, i.e. the diaphragm and the upper cover 1 enclose the front sound cavity 10, and the magnetic circuit system 33 is received in the rear cavity 30. The sound outlet 11 and the front sound cavity 10 jointly form the front cavity 20.

[0033] The diaphragm 321 comprises a vibrating part 3211 in the shape of a ring, a folded ring part 3212 formed by bending and extending from the outer periphery of the vibrating part 3211, a fixed part 3213 formed by extending from the outer periphery of the folded ring part 3212 towards the basket 31, and a ball top 3214 fixed to the vibrating part 3211 near the side of the magnetic circuit system 33. The fixed part 3213 is fixed between the basket 31 and the support wall 12.

[0034] The opposite sides of the voice coil 322 are connected to an electrical signal through the connecting wire 323.

[0035] Specifically, as shown in FIGS. 5-6, the shell 100 comprises an inner wall surface 102 enclosing a receiving space 101, the basket 31 has a first width a along a first direction X, the first direction X is perpendicular to the vibrating direction of the diaphragm 321, the inner wall surface 102 of the shell 100 has a second width b along a second direction Y, the second direction Y intersects the first direction X and is in the same plane, and the first width a is greater than the second width b. It can be understood that in the embodiment, the first direction X and the second direction Y are defined to be in the same plane, i.e. the comparison is the width of the basket 31 and the width of the inner wall surface 102 of the shell 100 in the same cross-sectional plane. Since the first width a is greater than the second width b, the sound production unit 3 cannot be placed horizontally on the lower cover 2 along the second direction Y, and the sound production unit 3 is designed to be in an inclined state and fixed in the receiving space 101 of the shell 100. In this way, the sound production unit 3 with a greater width can be placed in the receiving space with the same width, so as to set the volume of the magnetic circuit system and the area of the diaphragm to be larger, thereby making the sound production unit 3 have more excellent acoustic performance.

[0036] In the embodiment, the cross section of the inner wall surface 102 of the shell 100 along the second direction Y is in the shape of a quadrilateral, the shell 100 comprises a first corner 21 and a second corner 22 arranged along the second direction Y, and a third corner 23 arranged opposite to the first corner 21 along the diagonal line, and one end of the basket 31 along the first direction X abuts against the first corner 21, and the other end is arranged between the second corner 22 and the third corner 23. Preferably, the cross section of the inner wall surface 102 of the shell 100 along the second direction Y is in the shape of a rectangle.

[0037] Further, the upper cover 1 comprises a top wall 14 opposite to the lower cover 2 and a side wall 15 connecting the upper cover 1 and the lower cover 2, and the support wall 12 is arranged on the side wall 15. Specifically, the shell 100 has a quadrilateral structure in the embodiment, and the side wall 15 comprises a first side wall 151 arranged opposite to each other along the second direction Y and a pair of second side walls 152 connected to the first side wall 151 and arranged opposite to each other, and the second width b is the distance between the two first side walls 151 along the second direction Y. In the embodiment, the sound outlet 11 is arranged on one of the first side walls 151.

[0038] Preferably, in order to place the sound emitting unit 3 with a larger width in the same width of the accommodating space 101, the two ends of the yoke 31 along the first direction can abut against the first corner portion 21 and the third corner portion 23, respectively.

[0039] Specifically, the magnetic circuit system 33 comprises a lower clamp plate 331 fixed to the yoke 31, a main magnetic steel 332 fixed to the lower clamp plate 331 close to the diaphragm 321, and a pair of auxiliary magnetic steels 333 arranged at intervals on the side of the main magnetic steel 332. In the embodiment, the magnetic circuit system 33 comprises two auxiliary magnetic steels 333, which are arranged on opposite sides of the main magnetic steel 332 along the first direction,

[0040] The lower clamp plate 331 comprises a bottom portion 3311 supporting the main magnetic steel 332, a side portion 3312 bent and extended from the edge of the bottom portion 3311 towards the diaphragm 321, and an extension portion 3313 bent and extended from one end of the side portion 3312 away from the bottom portion 3311 and away from the main magnetic steel 332 along the first direction.

[0041] The side portion 3312 comprises two and is arranged on opposite sides of the bottom portion 3311, respectively, and the lower clamp plate 331 further comprises two flanges 3314 bent and extended from the edges of the other two opposite sides of the bottom portion 3311 towards the diaphragm 321, respectively, and the two flanges 3314 correspond to the opposite sides of the main magnetic steel 332 and are arranged at intervals with the main magnetic steel 332, respectively, and the auxiliary magnetic steels 333 and the flanges 3314 are arranged at intervals with the main magnetic steel 332 to form a magnetic gap 40, which can better cover the main magnetic steel 332. The voice coil 322 is inserted and suspended in the magnetic gap 40.

[0042] The intersection between the surface of the auxiliary magnetic steel 333 close to the lower clamp plate 331 and the surface of the auxiliary magnetic steel 333 away from the main magnetic steel 332 along the first direction X has a chamfer structure. This design can match the magnetic circuit system 33 with the accommodating space to maximize the thickness of the middle region of the magnetic circuit system 33, i.e. the thickness of the lower clamp plate 331 and the main magnetic steel 332 can be increased.

[0043] The auxiliary magnetic steel 333 includes a first surface 3331 fixed to the lower clamping plate 331, a second surface 3332 parallel to the vibration direction and away from the main magnetic steel 332 in the first direction X, and a third surface 3333 connecting the first surface 3331 and the second surface 3332, the third surface 3333 extending from the edge of the first surface 3331 to the second surface 3332 in a direction towards the diaphragm 321 and away from the main magnetic steel 332; the first surface 3331 of the auxiliary magnetic steel 333 is fixed to the side of the extension 3313 of the lower clamping plate 331 facing the diaphragm 321; the third surface 3333 of the auxiliary magnetic steel 333 close to the lower cover 2 is spaced apart from the lower cover 2.

[0044] It can be understood that, along the vibration direction of the diaphragm 321, since the bottom 3311 of the lower clamping plate 331 is farther away from the diaphragm 321 than the extension 3313, the space between the diaphragm 321 and the bottom 3311 is larger, and the thickness of the main magnetic steel 332 can be set larger to enhance the magnetic field performance of the magnetic circuit system. Further, the magnetic circuit system 33 further includes an upper clamping plate 334 fixed to the side of the main magnetic steel 332 away from the lower clamping plate 331, a center magnetic steel 335 fixed to the side of the upper clamping plate 334 away from the main magnetic steel 332, and an edge clamping plate 336 fixed to the side of the auxiliary magnetic steel 333 away from the lower clamping plate 331. The center magnetic steel 335 is arranged in the increased space between the bottom 3311 and the diaphragm 321, further improving the magnetic driving force of the magnetic circuit system 33, so that the acoustic performance of the sound emitting unit 3 is better.

[0045] In addition, the region of the spherical top 3214 corresponding to the center magnetic steel 335 is bent and extends away from the magnetic circuit system 33. This design can provide space for the center magnetic steel 335 to further increase the thickness of the center magnetic steel 335, thereby improving the magnetic field performance of the magnetic circuit system 33.

[0046] When the smart wearable glasses temple 1000 of the embodiment is in use, the sound outlet 11 is close to the human ear so that the experience person can hear the sound more clearly. The other first side wall 151 of the upper cover 1 is further provided with a leakage hole 13 penetrating therethrough, the leakage hole 13 communicates the rear cavity 30 with the outside, and the leakage hole 13 is located on the side of the smart wearable glasses temple 1000 away from the human ear. Since the sound waves emitted by the leakage hole 13 and the sound waves emitted by the sound outlet 11 are opposite in phase, the sound waves emitted by the leakage hole 13 can be cancelled out, thereby reducing the leakage of sound and improving the acoustic experience of the user.

[0047] Compared with the related art, the smart wearable glasses leg 1000 of the embodiment can place the sound emitting monomer 3 with a larger width in the same width of the accommodation space 101, so as to improve the vibration amplitude area and the magnetic circuit volume of the sound emitting monomer 3, and further improve the acoustic performance of the sound emitting monomer 3, by setting the first width a of the yoke 31 of the sound emitting monomer 3 to be greater than the second width b of the inner wall surface 102 of the shell 100, i.e. by designing the sound emitting monomer 3 to be fixed in the inclined state in the accommodation space 101 of the shell 100.

[0048] Embodiment two
