Taking "A and / or B" as an example, it includes solution A, or solution B, or a solution that satisfies both A and B at the same time.

[0048] The present utility model provides an electric shaver.

[0049] In the embodiments of the present utility model, please refer to Figures 1 to 6 , the electric shaver includes a housing assembly 100 and a linear motor 200; the housing assembly 100 forms a cavity 110, and the housing assembly 100 has a transparent window 120 for observing the cavity 110; the linear motor 200 is installed in the cavity 110, the linear motor 200 includes a motor frame 210 and a motor main body 220 installed in the motor frame 210, and the motor main body 220 includes a movable part 221 that can reciprocate relative to the motor frame 210; at least a part of the movable part 221 is exposed outside the motor frame 210 and is disposed corresponding to the transparent window 120.

[0050] In this embodiment, the housing assembly 100 provides installation and protection for the internal structures of the electric shaver, such as the motor, battery, etc. The output end of the linear motor 200 is connected to the cutter head assembly 400 through an output shaft to drive the moving cutter of the cutter head assembly 400 to reciprocate relative to the stationary cutter to cut hair. The linear motor 200 can specifically be a magnetic levitation linear motor 200. In other embodiments, it can also be other types of linear motors 200, as long as it can drive the moving cutter of the cutter head assembly 400 to move linearly. Using the linear motor 200 in the electric shaver has high precision, fast response speed, high sensitivity, reliable operation, and small weight and volume, which is beneficial to the miniaturization of the electric shaver. The electric shaver can use only one linear motor 200 to drive the moving cutter, or two linear motors 200, which is not specifically limited here.

[0051] It is possible to make part or all of the housing assembly 100 transparent to form the transparent window 120, so that the movement of the linear motor 200 in the cavity 110 can be observed through the transparent window 120. The shape of the transparent window 120 can be various. For example, the transparent window 120 can be rectangular, circular, strip-shaped, polygonal, irregular, etc., and can be selected and designed according to actual needs, which is not specifically limited here. The size of the transparent window 120 is also not specifically limited here, and the size of the transparent window 120 can be designed according to the position and area of the movable part 221 to be observed.

[0052] There can be many types and forms of the linear motor 200. The motor bracket 210 is used to provide support and installation for the motor body 220. The motor brackets 210 of different linear motors 200 are different. Some motor brackets 210 of the linear motor 200 are frame-like structures, and some motor brackets 210 of the linear motor 200 are suspension arm structures or only have a base, so that the movable part 221 is at least partially exposed outside the motor bracket 210 to be arranged corresponding to the transparent window 120, which means that the motor bracket 210 will not block or completely block the movable part 221 at the position corresponding to the transparent window 120, and the movable part 221 of the motor body 220 can be partially or completely observed through the transparent window 120. In this way, the user can directly observe the movable part 221 of the motor body 220 through the transparent window 120, that is, the user can directly observe the reciprocating movement of the linear motor 200.

[0053] The movable parts 221 of different linear motors 200 may be different. For example, in some linear motors 200, only the moving component 224 and the leaf spring supporting the moving component 224 can reciprocate. Then, the movable part 221 of this type of linear motor 200 only includes the moving component 224 and the leaf spring. In other linear motors 200, the driving component 222 is suspended on the motor frame 210 through an elastic suspension, so that the driving component 222 can also reciprocate to a certain extent. Therefore, the movable part 221 of this type of linear motor 200, in addition to including the moving component 224 and the leaf spring, also includes the driving component 222 and the elastic suspension. Of course, there are other types of linear motors 200, which will not be elaborated one by one here. As long as at least part of the movable part 221 that enables the linear motor 200 to reciprocate is arranged corresponding to the transparent window 120, that is, the reciprocating motion of all or part of the movable part 221 can be observed through the transparent window 120.

[0054] In the present utility model, by providing a transparent window 120 on the housing assembly 100 of the electric shaver to observe the accommodating cavity 110, the linear motor 200 is installed in the accommodating cavity 110. The linear motor 200 includes a motor frame 210 and a motor main body 220 installed in the motor frame 210. The motor main body 220 includes a movable part 221 that can reciprocate relative to the motor frame 210; at least part of the movable part 221 is exposed from the motor frame 210 and is arranged corresponding to the transparent window 120. In this way, the user can observe the reciprocating motion of the movable part 221 of the linear motor 200 in the accommodating cavity 110 from the outside of the electric shaver through the transparent window 120, that is, it can be observed from the outside whether the linear motor 200 is running normally, improving the convenience of maintenance; at the same time, making the whole electric shaver have a stronger mechanical sense and a sense of technology, giving users a new visual impact and visual experience, and thus greatly enhancing the competitiveness of the product.

[0055] Specifically, please refer to Figures 1 to 10 , the transparent window 120 is provided on the side wall surface of the housing assembly 100 extending along the reciprocating motion direction of the movable part 221. Since the movable part 221 of the linear motor 200 reciprocates along a preset direction, the transparent window 120 is provided on the side wall surface of the housing assembly 100 extending along the reciprocating motion direction of the movable part 221. Compared with being provided on other side wall surfaces of the housing assembly 100, the reciprocating motion of the movable part 221 can be directly observed from the front, that is, the reciprocating motion observed by the user is in the left-right direction, rather than the front-back direction, to ensure the visual effect.

[0056] In an embodiment, as Figures 2 to 8As shown in the figure, the housing assembly 100 includes a housing 130 and a transparent panel 140. A cavity 110 is formed inside the housing 130, and a visual window 136 communicating with the cavity 110 is provided on the housing 130. The transparent panel 140 is fixedly connected to the housing 130 and covers the visual window 136 to at least partially form a transparent window 120.

[0057] In this embodiment, the housing 130 can be made of a highly durable and drop-resistant material such as plastic or metal. The transparent panel 140 can specifically be made of a transparent material such as glass, quartz, or transparent plastic, as long as the movable part 221 of the linear motor 200 can be clearly observed from the outside through the transparent panel 140. Specifically, the transparent panel 140 can be embedded in the outer surface of the housing 130 and adhesively fixed to the housing 130. Of course, the transparent panel 140 can be fixed on the outer surface of the housing 130, or on the inner surface of the housing 130, or embedded in the periphery of the visual window 136, as long as the transparent panel 140 can cover the visual window 136. The transparent panel 140 can only cover the visual window 136, or can also cover a part of the periphery of the visual window 136. By making the housing assembly 100 include the housing 130 and the transparent panel 140, rather than making the entire housing assembly 100 of a transparent material, on the one hand, the structural strength and drop resistance of the product can be improved, and on the other hand, the user's line of sight can be concentrated on the movable part 221 of the linear motor 200, thereby giving the user a stronger visual impact.

[0058] In a specific embodiment, please refer to Figure 2 、 Figures 4 to 7 , an opening is provided at the top of the housing 130, and a top cover 170 is installed at the opening. The motor bracket 210 is fixedly connected to the top cover 170. Fixing the linear motor 200 to the top cover 170 can reduce the assembly error of the motor 200. It can be understood that since the drive rod of the linear motor 200 will pass through the top cover 170, by directly fixing the linear motor 200 to the top cover 170, the connection part between the drive rod of the linear motor 200 and the cutter head can be accurately corresponded, improving the assembly accuracy and reducing noise, etc. Especially when the electric shaver uses multiple cutter heads, multiple drive rods can be aligned with the multiple cutter heads one by one.

[0059] In one embodiment, as shown in Figures 1 to 10 , the housing 130 includes a housing main body 131 and a mounting plate 135. A cavity 110 is formed inside the housing main body 131, a mounting opening 132 is provided on the housing main body 131, the mounting plate 135 is fixedly connected to the housing main body 131 and covers the mounting opening 132, and a visual window 136 is provided on the mounting plate 135. The transparent panel 140 is fixedly connected to the housing main body 131 and covers the periphery of the mounting plate 135.

[0060] In this embodiment, the mounting plate 135 and the shell body 131 can be fixedly connected by bonding, embedding, etc. Specifically, the outer surface of the shell body 131 is provided with an embedding groove, and the bottom wall of the embedding groove is provided with a mounting opening 132, and the mounting plate 135 is adapted to be embedded in the embedding groove. The transparent panel 140 covers the periphery of the mounting plate 135, so that the area of the transparent panel 140 can be larger than the area of the mounting plate 135, so that the transparent panel 140 can completely cover the mounting plate 135. In this way, the transparent panel 140 can cover the mounting plate 135 to improve the connection stability between the mounting plate 135 and the shell body 131, and can ensure the integrity and consistency of the outer surface of the shell 130, and can also increase the transparent area of the whole machine and improve the product texture.

[0061] It is understandable that the size of the installation opening 132 is larger than the size of the visual window 136. By opening the installation opening 132 on the shell body 131, it is more convenient to connect and install the motor, battery, circuit board, light board, etc. in the shell body 131 through the installation opening 132. In addition, by making the installation plate 135 independent of the shell body 131, more complex installation structures, such as buckles, installation flanges 137 for fixing the transparent baffle 150, etc., can be set on the installation plate 135, thereby making it more convenient to form and manufacture the shell 130. The shape and size of the installation opening 132 can be selected and designed according to actual needs. For example, the installation opening 132 is generally rectangular as a whole, which is not specifically limited here.

[0062] In one embodiment, please refer to Figure 2 , Figure 3 , Figures 7 to 11 An indicator light 300 is provided in the cavity 110, and a light guide hole 138 is opened in the mounting plate 135 corresponding to the indicator light 300. The housing assembly 100 also includes a metal plate 160, which is arranged between the mounting plate 135 and the transparent panel 140, that is, the metal plate 160 covers the side of the mounting plate 135 facing the transparent panel 140 and is arranged away from the visible window 136. The metal plate 160 is opened with a plurality of light-transmitting micro-holes 161 corresponding to the light guide hole 138.

[0063] In this embodiment, an indicator light PCB board is further provided in the cavity 110, and the indicator light PCB board can be specifically fixedly installed on the mounting plate 135. It can be understood that the mounting plate 135 is usually made of plastic material to facilitate the formation of complex structures. Due to its polymer characteristics and plasticity, plastic is prone to deformation and shrinkage during the processing, resulting in the shape and size of the micro-holes being difficult to control. By providing the metal plate 160 and opening a plurality of light-transmitting micro-holes 161 on the metal plate 160, compared with the method of directly opening a plurality of light-transmitting micro-holes 161 on the mounting plate 135, the structural strength can be increased, and by opening micro-holes on the metal plate 160, holes with higher precision and smoother edges can be obtained, making the indication effect of the plurality of light-transmitting micro-holes 161 better. The metal plate 160 avoids the visual window 136 to prevent blocking the visual window 136.

[0064] Specifically, a light guide member can be provided in the light guide hole 138 to make the light emitted by the indicator light 300 more concentrated and uniform through the light guide hole 138. The plurality of light-transmitting micro-holes 161 can specifically form indication patterns such as power on / off, flight mode, battery level, etc. By opening the light guide hole 138 on the mounting plate 135 and opening a plurality of light-transmitting micro-holes 161 on the metal plate 160, the light emitted by the indicator light 300 can pass through the light guide hole 138 and the plurality of light-transmitting micro-holes 161 and penetrate onto the transparent panel 140, and then be observed by the user. The whole machine housing makes full use of the transparent panel 140 to transmit the indicator light, eliminating the need to drill light-transmitting holes and fill light-transmitting glue on the outer shell 130, thereby simplifying the process. And the visual effect of the indicator light observed by the user through the transparent panel 140 is better.

[0065] In one embodiment, please refer to Figure 2 、 Figures 6 to 20 , the outer shell assembly 100 further includes a transparent baffle 150 provided inside the transparent panel 140. The transparent baffle 150 is fixedly connected to the mounting plate 135 and covers the visual window 136.

[0066] In this embodiment, the transparent baffle 150 and the mounting plate 135 can be detachably fixedly connected or non-detachably fixedly connected. The transparent baffle 150 is fixedly connected to the mounting plate 135 so that the transparent baffle 150 can be disassembled and assembled integrally with the mounting plate 135, improving the assembly efficiency of the whole machine. The transparent baffle 150 can specifically adopt transparent materials such as glass and transparent plastic. The material of the transparent baffle 150 can be the same as or different from that of the transparent panel 140. It should be noted that even with the provision of the transparent baffle 150, the user can still observe the linear motor 200 in the cavity 110 through the transparent panel 140 and the transparent baffle 150.

[0067] The transparent baffle 150 can cover the outside of the visual window 136, can also cover the inside of the visual window 136, or be embedded in the periphery of the visual window 136. By arranging the transparent baffle 150 to cover the visual window 136, dust, lint, etc. in the cavity 110 can be prevented from adhering to the transparent panel 140, affecting the visual effect of the transparent panel 140. When the transparent baffle 150 is used to cover the visual window 136, the transparent baffle 150 and the visual window 136 can be arranged in a shape-matching manner, so as to reduce the occupied space of the transparent panel 140 while meeting the dust-proof effect. Optionally, the transparent baffle 150 is hermetically covered and arranged on the visual window 136. In this way, the sealing effect of the transparent baffle 150 can be further improved, and dirt such as water vapor, dust, and lint can be prevented from adhering to the inner wall surface of the transparent panel 140 at the same time.

[0068] In an embodiment, the transparent baffle 150 and the transparent panel 140 are arranged at an interval. Specifically, the interval between the transparent baffle 150 and the plate surface of the transparent panel 140 is 3 mm to 5 mm. By providing a certain interval between the transparent panel 140 and the transparent baffle 150, even if there is dust inside the transparent baffle 150, it is not easy to notice when viewed from the outer transparent panel 140.

[0069] Furthermore, please refer to again Figures 6 to 20 , the transparent baffle 150 includes a plate body 151 and a surrounding edge 152 extending around the outer periphery of the plate body 151; the mounting plate 135 protrudes away from the transparent panel 140 with a mounting flange 137 surrounding the visual window 136, and the inner peripheral wall of the surrounding edge 152 is lapped on the outer peripheral wall of the mounting flange 137.

[0070] In this embodiment, the transparent baffle 150 is lapped with the mounting flange 137 outside the visual window 136 through the surrounding edge 152. On the one hand, it can pre-position the assembly of the transparent baffle 150 and the housing 130, increase the installation area of the transparent baffle 150 and the housing 130, and improve the connection stability between the two. On the other hand, the fitting of the surrounding edge 152 and the mounting flange 137 can further improve the sealing performance of the transparent baffle 150 and the housing 130, so as to further prevent dirt such as water vapor, dust, and lint from adhering to the inner wall surface of the transparent panel 140. In addition, by making the transparent baffle 150 lap with the mounting flange 137 outside the visual window 136 through the surrounding edge 152, the distance between the transparent baffle 150 and the plate surface of the transparent panel 140 can also be increased, so as to further reduce the visual impact of the dust inside the transparent baffle 150 on the transparent panel 140.

[0071] Furthermore, as Figures 6 to 16 shown, convex ears 153 are provided on opposite sides of the plate body 151, and one of the inner walls of the convex ears 153 and the mounting plate 135 is provided with a card hole 154, and the other is provided with a hook 139 that is snap-fitted with the card hole 154.

[0072] In this embodiment, the transparent baffle 150 is snap-fitted and fixed to the mounting plate 135, making the installation more convenient and stable. By providing lugs 153 on both sides of the plate body 151 and providing snap holes 154 / hooks 139 on the lugs 153, which are snap-fitted with the hooks 139 / snap holes 154 on the inner wall surface of the mounting plate 135, there is no need to make the peripheral edge 152 snap-fitted with the mounting flange 137, which can reduce the extension height of the mounting flange 137 and the peripheral edge 152, and further reduce the occupied space of the transparent baffle 150 in the thickness direction, so that the overall structure of the machine can be set to be more compact and small, which is beneficial to the miniaturization of the whole electric shaver.

[0073] In another embodiment, please refer to Figures 17 to 20 , the peripheral edge 152 is snap-fitted and fixed to the mounting flange 137. Snap fasteners / snap holes 154 can be provided on opposite sides of the peripheral edge 152, and corresponding snap holes 154 / snap fasteners can be provided on the mounting flange 137 to make the peripheral edge 152 snap-fitted with the mounting flange 137. By making the peripheral edge 152 snap-fitted with the mounting flange 137, the peripheral edge 152 and the mounting flange 137 are fully utilized, and there is no need to additionally provide lugs 153, which can simplify the structure of the transparent baffle 150. It can be understood that if the peripheral edge 152 is to be snap-fitted with the mounting flange 137, the protruding height of the peripheral edge 152 and the mounting flange 137 needs to be set larger.

[0074] In one embodiment, please refer to Figures 1 to 10 , the cross-section of the housing main body 131 extends in a strip shape along the reciprocating movement direction of the motor main body 220, and the housing main body 131 has two first side walls 133 opposite to each other in its width direction, and at least one first side wall 133 is provided with a mounting opening 132.

[0075] In this embodiment, since the size of the linear motor 200 in the direction of reciprocating movement of its output end is larger than its size in the width direction, by making the cross-section of the housing main body 131 extend in a strip shape along the reciprocating movement direction of the motor main body 220, while satisfying the motor installation, the whole machine is made more compact and small. By providing the mounting opening 132 on the first side walls 133 opposite to each other in the width direction of the housing main body 131, that is, by providing the mounting opening 132 on the side wall with the largest area of the housing main body 131, the size of the mounting opening 132 can be designed larger, and further it is more convenient to install the internal structure of the housing main body 131.

[0076] In one embodiment, the ratio of the area of the transparent panel 140 to the area of the first sidewall 133 is greater than or equal to 0.5 and less than or equal to 1. Specifically, the ratio of the area of the transparent panel 140 to the area of the first sidewall 133 can be 0.5, 0.6, 0.65, 0.7, 0.8, 0.9, 1, etc. When the ratio of the area of the transparent panel 140 to the area of the first sidewall 133 is less than 0.5, the area of the transparent panel 140 is too small. In other words, the area of the mounting opening 132 is too small, which is not conducive to the wiring and installation operations of the internal structure of the housing 130, and the transparent area of the whole machine is too small, resulting in poor product texture. By making the ratio of the area of the transparent panel 140 to the area of the first sidewall 133 greater than or equal to 0.5 and less than or equal to 1, the area of the mounting opening 132 can be increased, which is more convenient for the wiring and installation operations of the internal structure of the housing 130, and the transparent area of the whole machine is larger, with a stronger visual impact and better product texture.

[0077] In one embodiment, as Figure 1 , Figure 2 , Figure 4 , Figure 6 shown, the outer surface of the transparent panel 140 includes a flat surface 141 and an outer arc surface 142 surrounding the outer periphery of the flat surface 141; an installation groove 134 is formed on the housing body 131, and an installation opening 132 is formed on the bottom wall of the installation groove 134. The transparent panel 140 is adaptively embedded in the installation groove 134, the flat surface 141 corresponds to the installation opening 132, and the outer arc surface 142 is smoothly transitioned with the outer peripheral surface of the housing body 131.

[0078] In this embodiment, the flat surface 141 of the transparent panel 140 corresponds to the installation opening 132, so that the outer arc surface 142 corresponds to the bottom wall of the installation groove 134. In this way, the visual focus can be realized at the installation opening 132 instead of the bottom wall of the installation groove 134, thereby improving the product texture. At the same time, the smooth transition of the outer arc surface 142 of the transparent panel 140 and the outer peripheral surface of the housing body 131 can ensure the overall consistency of the appearance of the whole machine and avoid the situation of being uncomfortable to hold.

[0079] In one embodiment, the electric shaver further includes a lighting component (not shown) installed in the cavity 110. The irradiation area of the lighting component (not shown) covers the side of the movable part 221 facing the transparent window 120. Specifically, the lighting component (not shown) may include a stroboscopic lamp. Of course, the lighting component (not shown) may also include an ambient light, a colored light, etc., and the specific type of the lighting component can be selected and designed according to actual needs, and will not be specifically limited here. By making the electric shaver include the lighting component (not shown), the lighting component (not shown) can irradiate the side of the movable part 221 of the linear motor 200 facing the transparent window 120. In this way, the side of the movable part 221 of the linear motor 200 that can be directly observed by the user is illuminated, and the user can more clearly observe the reciprocating motion of the linear motor 200 from the outside, making the visual effect of the electric shaver stronger.

[0080] Further, the lighting component (not shown) includes a stroboscopic lamp, and the absolute value of the difference between the movement frequency of the movable part 221 and the flashing frequency of the stroboscopic lamp, divided by the movement frequency of the movable part, is greater than 0 and less than or equal to 35%. Specifically, the absolute value of the difference between the movement frequency of the movable part 221 and the flashing frequency of the stroboscopic lamp, divided by the movement frequency of the movable part, can be specifically 5%, 10%, 15%, 18%, 20%, 25%, 30%, 35%, etc.

[0081] In this embodiment, when the flashing frequency of the stroboscopic lamp is close to the movement frequency of the movable part 221, although the movable part 221 is moving at a high speed, it seems to be moving slowly. By making the absolute value of the difference between the movement frequency of the movable part 221 and the flashing frequency of the stroboscopic lamp, divided by the movement frequency of the movable part, greater than 0 and less than or equal to 35%, it makes the user observe from the outside that the high-speed moving movable part 221 is moving slowly, so that the user's perception is softer and more comfortable, and the user's visual experience can be improved.

[0082] Further, the lighting component (not shown) is fixed to the wall surface of the cavity 110 adjacent to the transparent window 120. Specifically, the lighting component (not shown) can be fixed on the housing assembly 100, for example, fixed on the inner wall surface of the mounting plate 135 facing the cavity 110, the bottom wall or side wall of the cavity 110 of the housing body 131. The lighting component (not shown) can also be fixed on the motor bracket 210 or the mounting plate 135, or can also be fixed on other mounting brackets inside the housing, as long as the irradiation area of the lighting component (not shown) covers the side of the movable part 221 facing the transparent window 120.

[0083] In one embodiment, as Figures 3 to 6As shown, the motor body 220 includes a driving component 222, a moving component 224, an elastic support unit 225 and an elastic suspension unit 226; both ends of the moving component 224 are connected to the driving component 222 through the elastic support unit 225, so that it can be driven by the driving component 222 to reciprocate along a preset direction under the action of electromagnetic force; both ends of the driving component 222 are connected to the motor frame 210 through the elastic suspension unit 226, so that the driving component 222, the moving component 224, the elastic support unit 225 and the elastic suspension unit 226 form a movable part 221.

[0084] In this embodiment, the motion component 224 includes a permanent magnet and a magnet support seat, the permanent magnet is fixed on the magnet support seat, and the two ends of the magnet support seat are connected to the driving component 222 through an elastic support unit 225. The driving component 222 specifically includes an iron core, a winding frame and a coil 223, and the coil 223 is wound on the winding frame and installed on the iron core through the winding frame. The iron core can be a U-shaped iron core, an E-shaped iron core, etc., and different types of iron cores can be selected according to actual needs, which are not specifically limited here. After the coil 223 is passed through the positive and negative alternating current, the motion component 224 forms an electromagnet, and the driving component 222 is driven to reciprocate along a preset direction through the magnetic induction effect of the electromagnet and the permanent magnet of the driving component 222. In actual use, by connecting the cutter head assembly 400 to the connecting seat of the motion component 224, the linear motor 200 can drive the blade to reciprocate rapidly. The elastic support unit 225 can specifically include structures such as leaf springs, and the elastic suspension unit 226 can specifically include structures such as shrapnel and flexible plates.

[0085] By connecting the two ends of the motion component 224 to the drive component 222 through an elastic support member, and connecting the two ends of the drive component 222 to the motor frame 210 through an elastic suspension member, the drive component 222 and the motion component 224 are suspended on the motor frame 210 as a whole. Since the weight of the drive component 222 is much greater than the weight of the motion component 224, the swing amplitude of the elastic suspension member relative to the frame is smaller, and the shock absorption effect is better. By adopting this type of linear motor 200, the drive component 222 and the elastic suspension unit 226 also form a movable part 221. Since the movement amplitude of the drive component 222 and the elastic suspension unit 226 is smaller and the frequency is lower than that of the motion component 224 and the elastic support unit 225, it can provide users with a different visual experience.

[0086] In one embodiment, please refer again to Figure 3 , Figure 4 and Figure 6 A revealing window 211 is formed on the side wall of the motor frame 210 facing the transparent window 120 and corresponding to the elastic supporting unit 225 and / or the driving assembly 222 .

[0087] Since elastic suspension space needs to be provided for the drive assembly 222, the motor mount 210 is designed as a frame structure. By providing an exposure window 211 on the side wall of the motor mount 210 facing the visual window 136, the elastic support unit 225 and / or the drive assembly 222 can be exposed through the exposure window 211 to the transparent window 120, and the user can observe the reciprocating motion of the elastic support unit 225 and the drive assembly 222 through the transparent window 120 and the exposure window 211 of the motor mount 210. Moreover, other parts of the motor mount 210 except the exposure window 211 can block the motor body, so that only the parts that the user wants to observe are exposed by the motor mount 210, which can further enhance the visual experience of the product.

[0088] Further, as Figures 2 to 6 shown, the drive assembly 222 includes a mounting base 227 and a coil 223. The moving assembly 224 is fixedly connected to the mounting base 227. The upper end of the elastic support unit 225 is fixedly connected to the moving assembly 224, and the lower end is fixedly connected to the mounting base 227; the lower end of the elastic suspension unit 226 is fixedly connected to the mounting base 227, and the upper end is fixedly connected to the motor mount 210; the elastic support unit 225 includes a leaf spring, and the exposure window 211 is provided corresponding to the leaf spring and the coil 223.

[0089] In this embodiment, the moving assembly 224 is fixedly connected to the mounting base 227. Through the mounting base 227 and the elastic suspension unit 226, the drive assembly 222 can be suspended in the motor mount 210. The fixing methods of the elastic support unit 225 with the moving assembly 224 and the mounting base 227, and the fixing method of the elastic suspension unit 226 with the mounting base 227 can be screw connection, riveting, welding, etc., which are not specifically limited herein. By making the exposure window 211 correspond to the leaf spring supporting the moving assembly 224 and the coil 223 of the drive assembly 222, since the reciprocating motion forms of the coil 223 and the leaf spring are different, different visual experiences can be given to the user, and thus the competitiveness of the product can be greatly enhanced.
