[0060] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The manner described in the following exemplary embodiments does not represent all manner consistent with this application. Rather, they are merely examples of apparatuses consistent with some aspects of this application as detailed in the appended claims.

[0061] Referring to Figures 1-12, this application provides an alarm clock 10.

[0062] The alarm clock 100 includes a housing assembly 1 and a sound-emitting device 2, including a housing support 11, a rear cover 12, and a front cover 13; the front cover covers the front side of the housing support 11 and forms a working space 14 with the housing support 11; the rear cover 12 covers the rear side of the housing support 11 and forms a receiving space 15 with the housing support 11; a through hole 111 is provided on the side of the housing support 11 facing the rear cover 12, and the through hole 111 connects the working space 14 and the receiving space 15.

[0063] The sound-generating device 2 is fixed to the shell support 11, and at least a portion of the sound-generating device 2 enters the through hole 111 and is exposed to the receiving space 15.

[0064] The rear cover plate 12 is provided with a sound outlet channel 121 that extends through the thickness direction. The sound outlet channel 121 is connected to the accommodating space 15 so that the sound emitted by the sound-emitting device 2 is conducted outward through the accommodating space 15 and the through hole 111.

[0065] In the above configuration, the shell support 11 is used to fix the sound-generating device 2, and at least a portion of the structure of the shell support 11 divides the internal space of the shell assembly 1 into a relatively independent working space 14 and a receiving space 15. The sound-generating device 2 is located in both the working space 14 and the receiving space 15 to maximize the use of space and achieve a compact internal space configuration.

[0066] As shown in Figure 3, the shell support 11 includes a support plate 112, and the through hole 111 is provided in the support plate 112. The support plate 112 and the rear cover plate 12 are detachably connected and form the receiving space 15. The sound-generating device 2 is fixed to the support plate 112.

[0067] In the above configuration, the shell bracket 11 is used to fix the sound-generating device 2 by means of the bracket plate 112. The bracket plate 112 not only serves to fix the sound-generating device 2, but also serves to divide the space, so as to make the most of the space and achieve a compact internal space configuration.

[0068] As shown in Figures 5 and 6, a positioning protrusion 1121 is formed on the side of the bracket plate 112 away from the rear cover plate 12.

[0069] The alarm clock 100 also includes a first fastener 3, which enters the positioning protrusion 1121 and fixes the bracket plate 112 and the sound-generating device 2.

[0070] The above method achieves a fixed connection between the support plate 112 and the sound-generating device 2. Meanwhile, the positioning protrusion 1121 is located on the side of the support plate 112 away from the rear cover plate 12, i.e., in the larger working space 14, thus achieving efficient use of space.

[0071] Referring to Figures 5 and 6, the sound-generating device 2 includes a positioning plate 21, which is fixed to one end of the support plate 112 facing the front cover. The positioning plate 21 has a positioning hole 212, through which the first fastener 3 passes and into the positioning protrusion 1121, for fixing the sound-generating device 2 to the shell support 11.

[0072] The above method achieves a fixed connection between the support plate 112 and the sound-generating device 2.

[0073] Continuing as shown in the figure above, the sound-generating device 2 includes a diaphragm 22 and a vibration system 23. The vibration system 23 vibrates, causing the diaphragm 22 to vibrate and generate sound waves. Specifically, the vibration system 23 can be a magnet system to provide a static magnetic field. A voice coil can be fixed on the diaphragm 22, and the interaction between the magnet system and the voice coil generates a driving force to drive the diaphragm 22 to vibrate.

[0074] In this embodiment, the diaphragm 22 is fixed to the positioning plate 21, and at least a portion of the structure of the diaphragm 22 is located in the receiving space 15. At this time, the diaphragm 22 vibrates within the receiving space 15 to generate sound, which is then directly transmitted outward through the sound outlet channel 121. Of course, the receiving space 15 can also serve as a resonant cavity to improve the sound quality. The vibration system 23 has a relatively large volume, with at least a portion of its structure located in the working space 14, to maximize the use of the effective space within the shell assembly 1 and achieve miniaturization of the alarm clock 100.

[0075] As shown in Figure 7, a first mating part 122 is provided on the side of the rear cover plate 12 facing the support plate 112, and a second mating part 1122 is provided on the side of the support plate 112 facing the rear cover plate 12.

[0076] One of the first mating part 122 and the second mating part 1122 is a positioning protrusion, and the other is a positioning recess, which are snap-fit ​​connected. In this embodiment, the first mating part 122 is a positioning protrusion, and the second mating part 1122 is a positioning recess. Of course, in other embodiments, the opposite can be true. Alternatively, in other embodiments, the first mating part 122 and the second mating part 1122 can also be magnetically engaged. Through the above methods, the rear cover plate 12 and the shell bracket 11 can be quickly positioned.

[0077] Continuing as shown in Figure 8, a third mating member 123 is provided on the side of the rear cover plate 12 facing the support plate 112, and a fourth mating member 1123 is provided on the side of the support plate 112 facing the rear cover plate 12. The third mating member 123 is a protruding structure, and the fourth mating member 1123 is a through hole. The alarm clock 100 includes a second fastener 4, which passes through the fourth mating member 1123 and enters the third mating member 123 to achieve a fixed connection. Through the above, a fastening connection between the rear cover plate 12 and the shell support 11 is achieved.

[0078] It should be noted that in this embodiment, the first mating part 122 and the second mating part 1122 can be used to limit the rear cover plate 12 and the shell bracket 11 to a certain extent. Then, the third mating part 123, the fourth mating part 1123 and the second fastener 4 are used to achieve a fast connection between the rear cover plate 12 and the shell bracket 11.

[0079] As shown in Figure 9, and if necessary, in conjunction with Figures 1-7, the rear cover 12 includes a rear cover unit 124 and a shielding unit 125.

[0080] The rear cover unit 124 is connected to the shell support 11, and the shielding unit 125 is located between the rear cover unit 124 and the shell support 11. In this embodiment, the first mating member 122 and the third mating member 123 are both disposed on the rear cover unit 124, and the second mating member 1122 and the fourth mating member 1123 are both disposed on the support plate 112.

[0081] In this embodiment, the first mating member 122 and the second mating member 1122 are first used to limit the rear cover unit 124 and the shell support 11 to a certain extent, so as to restrict the shielding unit 125 to the area between the rear cover unit 124 and the shell support 11. Then, the second fastener 4 is used to achieve a fastening connection between the rear cover plate 12 and the shell support 11.

[0082] The rear cover unit 124 is provided with a strip groove 1241 extending along its thickness direction, and the shielding unit 125 is provided with a second sound outlet hole 1251 extending along its own thickness direction. The strip groove 1241 and the second sound outlet hole 1251 together form the sound outlet channel 121. At this time, the sound emitted by the sound-emitting device 2 passes through the receiving space 15, first through the second sound outlet hole 1251, then through the strip groove 1241, and finally outward.

[0083] It should be noted that in Figure 9, the second sound outlet 1251 on the shielding unit 125 is only for illustration. In actual products, the number, size, and arrangement of the second sound outlet 1251 can be designed according to actual needs. Furthermore, to more clearly illustrate the positional relationship and structure of each component, the second sound outlet 1251 is not shown on the shielding unit 125 in some of the accompanying drawings.

[0084] Of course, in other embodiments, the rear cover unit 124 is provided with a first sound outlet hole (not shown) extending through the thickness direction, and the first sound outlet hole and the second sound outlet hole 1251 together form the sound outlet channel 121. In this case, the sound emitted by the sound-emitting device 2 passes through the receiving space 15 first through the first sound outlet hole, then through the second sound outlet hole 1251, and finally outward.

[0085] In this embodiment, the rear cover unit 124 is disposed on the outer side to enhance the appearance. Simultaneously, the rear cover unit 124 has a single, relatively large strip-shaped groove 1241. To ensure better waterproof and dustproof performance, a separate shielding unit 125 is provided. The shielding unit 125 has a single, relatively small second sound outlet 1251 to further improve waterproof and dustproof performance. In this embodiment, the shielding unit 125 covers the portion of the sound-generating device 2 exposed to the receiving space, thereby providing better protection for the sound-generating device 2.

[0086] As shown in Figures 8-10, a protruding limiting post 1242 is provided on the side of the back cover unit 124 facing the blocking unit 125. The side of the limiting post 1242 away from the back cover unit 124 abuts against the blocking unit 125 to limit the blocking unit 125.

[0087] Of course, in other embodiments, the limiting protrusion 1242 can also directly enter part of the second sound outlet hole 1251 provided on the blocking unit 125 to limit the blocking unit 125.

[0088] Referring to Figures 11 and 12, the alarm clock 100 includes a first circuit board 5, which is located in the receiving space 15 and fixed to the rear cover unit 124 and the housing bracket 11 of the rear cover plate 12. Of course, in other embodiments, the first circuit board 5 may only be fixed to the housing bracket 11, or only to the rear cover plate 12. The first circuit board 5 is provided with a control button 6 and a charging / discharging interface 7. The ends of the control button 6 and the charging / discharging interface 7 away from the first circuit board 5 pass through the rear cover plate 12 and are exposed. With the above arrangement, simple control of the alarm clock 100 can be achieved. In the above arrangement, a simple control button 6 and a charging / discharging interface 7 are provided in the receiving space 15, and a functionally simple first circuit board 5 is arranged therein.

[0089] Of course, in other embodiments, the first circuit board 5 may only have a control button 6 or a charging / discharging interface 7. The control button 6 can be used to control one or more of the following functions of the alarm clock 100: turning it on, turning it off, turning the volume on, turning the volume off, increasing the volume, and decreasing the volume. The charging / discharging interface 7 can be a charging interface used only to charge the energy storage cell in the alarm clock 100, a discharging interface used only to discharge to other electronic devices, or an interface that has both of the above functions.

[0090] The rear cover plate 12 has multiple raised strips 125 on the side away from the front cover plate 13, with adjacent raised strips 125 spaced apart. An operating area 1243 is also provided on the side of the rear cover plate 12 away from the front cover plate 13, where the control button 6 and / or charging / discharging interface 7 are exposed. The raised strips surround the periphery of the operating area 1243. This enhances the aesthetics while also protecting the operating area 1243.

[0091] In this embodiment, the strip groove 1241 is disposed between adjacent protrusions.

[0092] Furthermore, continuing to refer to Figures 11 and 12, the support plate 112 includes a body portion 1124 extending along the first direction X and a limiting portion 1125 extending along the second direction Y. The bottom of the rear cover plate 12 abuts against the limiting portion 1125 to provide a certain degree of limitation.

[0093] Alternatively, in other embodiments, the bottom of the rear cover plate 12 may be spaced apart from the limiting portion 1125.

[0094] It should be noted that the second direction Y is parallel to the direction from the rear cover plate 12 to the front cover plate 13, and the second direction Y is perpendicular to the first direction X.

[0095] The plane at the end of the limiting portion 1125 furthest from the front cover plate 13 is a first plane, and the plane at the end of the rear cover plate 12 furthest from the front cover plate 13 is a second plane. The first plane is farther from the front cover plate 13 than the second plane.

[0096] In the above configuration, the limiting portion 1125 protrudes relatively from the rear cover 12, which can provide a certain degree of protection for the rear cover 12 and the sound-generating device 2 located in the shell assembly 1. When the alarm clock 100 is accidentally dropped, the limiting portion 1125 can first withstand part of the impact force, thereby preventing the rear cover 12 from receiving excessive impact force directly.

[0097] In this embodiment, the first circuit board 5 is fixed to the rear cover plate 12. The above-mentioned arrangement can also protect the electronic components such as the first circuit board 5.

[0098] Referring to Figures 4-6, in this embodiment, the alarm clock 100 includes a second circuit board 8, which is electrically connected to the display panel 9, controller, energy storage cell, and other components of the alarm clock 100. The front cover 13 is used to fix the display panel 9. The energy storage cell and the second circuit board 8 are located in the working space 14. The controller cell is fixed to the second circuit board 8 and electrically connected to it. This arrangement allows the second circuit board 8 to be positioned close to the display panel of the alarm clock 100, saving space. To allow the first circuit board 5 and the second circuit board 8, located in different spaces, to be electrically connected so that components on the first circuit board 5 can conduct electrical signals with components on the second circuit board 8, a connecting plate 9 is provided in this application. One end of the connecting plate 9 is electrically connected to the first circuit board 5, and the other end is electrically connected to the second circuit board 8.

[0099] As shown in Figures 4-8, the support plate 112 is provided with a connection hole 1126. One end of the connection plate 9 is electrically connected to the first circuit board 5, and the other end passes through the connection hole 1126 into the working space 14 and is electrically connected to the second circuit board 8. The connection hole 1126 enables communication between the working space 14 and the accommodating space 15, providing space for the connection plate 9 to pass through.
