The sound outlet hole penetrating the bevel portion along the thickness direction can not only shorten the sound outlet path and reduce the sound loss of the sound transmitted along the sound outlet hole, but also change the sound outlet direction;

[0030] Specifically, since the hypotenuse part is inclined, the sound outlet holes extending in the thickness direction also form a certain angle with the mounting surface (wall surface) of the wall-mounted interaction device accordingly. Furthermore, an oblique incident angle is formed between the sound emission direction on the back of the wall-mounted interaction device and the mounting surface of the wall-mounted interaction device.

Detailed implementation manners

[0044] Embodiments of the present invention will be described in detail below. Examples of the embodiments are shown in the drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. Based on the embodiments in the implementation manners, it is intended to explain the present invention and should not be construed as a limitation to the present invention.

[0045] As used herein, the phrase "an embodiment", "an example" or "an instance" means that a particular feature, structure or characteristic described in connection with the embodiment itself can be included in at least one embodiment of the present disclosure. The appearances of the phrase "in one embodiment" in various positions in the specification do not necessarily refer to the same embodiment.

[0046] As Figure 1 、 Figure 2 Shown is a schematic structural diagram of an access control interaction device in the related art. The device includes a display panel 1, a housing 2, and a speaker 3. The display panel 1 is disposed in an opening on one side of the housing 2. The back plate 21 is provided on the back of the housing 2, and the sound outlet hole 4 is formed on the back plate 21. The speaker 3 transmits sound to the outside through the sound outlet hole 4 extending in the horizontal direction (i.e., the left-right direction when looking at the access control interaction device from the front in the normal use state where the access control interaction device is suspended on the wall).

[0047] However, due to the arc design at the edge of the back plate 21, there is not enough space at the edge to provide the speaker 3, resulting in a relatively long distance between the speaker 3 and the side of the access control interaction device. As a result, the length of the sound outlet hole 4 is relatively long, and the sound loss when the speaker 3 emits sound increases with the increase in the length of the sound outlet hole 4, thereby causing insufficient external volume of the device. Moreover, to facilitate the production of the horizontally extending sound outlet hole 4 at the edge of the back plate 21, as Figure 2 shown, a corresponding thickened portion 22 of the material also needs to be added inside the edge of the back plate 21 to form a complete structure of the sound outlet hole 4. The narrow sound outlet hole 4 and the thickened portion 22 of the material with excessive thickness result in poor manufacturability of this structure using injection molding or machining processes, thereby making it difficult to manufacture the housing 2 and increasing the process cost.

[0048] To solve the above technical problems, the present utility model provides a wall-mounted interaction device, such as Figure 3 , Figure 4 , Figures 6 to 9 shown, the wall-mounted interaction device includes a housing 20 and at least one sound-emitting device 30. One side of the housing 20 has an interaction surface (i.e., the surface on the side where the display panel 10 is provided in the figure). The side of the housing 20 facing away from the interaction surface has a back plate 100. The back plate 100 includes a mounting portion 110 and a beveled portion 120 provided at at least one side edge of the mounting portion 110. The mounting portion 110 is disposed opposite to the interaction surface. The distance between the beveled portion 120 and the interaction surface gradually decreases in the direction away from the center of the mounting portion 110, such as Figure 4 shown, the sound-emitting device 30 is disposed in the housing 20. At least one beveled portion 120 has a sound outlet hole 121. The sound outlet hole 121 penetrates the beveled portion 120 along the thickness direction of the beveled portion 120. The sound-emitting device 30 is communicated with the outside of the housing 20 through the sound outlet hole 121.

[0049] In the wall-mounted interaction device provided by the present utility model, the back plate 100 of the housing 20 forms a sound outlet hole 121 that penetrates along the thickness direction. The sound-emitting device 30 emits a sound signal to the outside of the housing 20 through the sound outlet hole 121, shortening the sound-emitting path of the sound-emitting device 30. The sound outlet hole 121 penetrating the beveled portion 120 along the thickness direction can not only shorten the sound-emitting path and reduce the sound loss of the sound transmitted along the sound outlet hole 121, but also change the sound-emitting direction;

[0050] Specifically, as Figure 4 shown, since the beveled portion 120 is inclined, the sound outlet hole 121 extending along the thickness direction also forms a certain angle with the installation surface (wall surface) of the wall-mounted interaction device correspondingly. Furthermore, the sound-emitting direction on the back of the wall-mounted interaction device forms an oblique incident angle with the installation surface of the wall-mounted interaction device. The sound wave is reflected by the installation surface to concentrate energy and propagate towards the front of the device (the arrow shown in the figure is the sound propagation direction), thereby being able to significantly improve the audio loudness (the gain is greater than 5 dB after testing), increasing the device volume, and ensuring the interaction experience of the user;

[0051] Moreover, the remaining parts of the housing 20 do not need to increase the material thickness as in the related art for making horizontal initial sound holes, ensuring the uniformity of the material thickness of the housing 20, thereby improving the manufacturability of the housing 20 and reducing the manufacturing process difficulty of the housing 20 of the wall-mounted interaction device.

[0052] It can be understood that the interaction surface is the surface facing the user side, and various function modules for realizing access control interaction with the user can be integrated thereon. For example, as an optional implementation manner of the present utility model, such as Figure 3 , Figure 4 , Figures 6 to 9As shown in the figure, the wall-mounted interaction device further includes a display panel 10. There is a display opening on the interaction surface of the housing, and the display panel 10 is arranged in the display opening. The display panel 10 can be used to show the images of visitors / homeowners on the other side, access control information, interaction interfaces, etc. to the user.

[0053] As an alternative embodiment of the present utility model, as Figure 8 shown in the figure, at least one side of the housing 20 along the transverse direction has an inclined edge portion 120 extending longitudinally (for example, two inclined edge portions 120 can be respectively arranged on both sides of the housing 20 along the transverse direction, namely the first inclined edge portion 120a and the second inclined edge portion 120b).

[0054] As an alternative embodiment of the present utility model, as Figure 8 shown in the figure, both sides of the housing 20 along the transverse direction respectively have a first inclined edge portion 120a and a second inclined edge portion 120b extending longitudinally, and a sound outlet hole 121 is arranged on the first inclined edge portion 120a.

[0055] As an alternative embodiment of the present utility model, one sound outlet hole 121 is arranged on the first inclined edge portion 120a.

[0056] In other embodiments of the present utility model, a plurality of sound outlet holes 121 can also be arranged on the first inclined edge portion 120a.

[0057] It can be understood that when only one of the first inclined edge portion 120a and the second inclined edge portion 120b is provided with the sound outlet hole 121, the side provided with the sound outlet hole 121 can be used facing the door side, so that the sound waves emitted can be reflected to the side of the user in front of the door.

[0058] In other embodiments of the present utility model, the sound outlet hole 121 can also be arranged on the second inclined edge portion 120b.

[0059] As an alternative embodiment of the present utility model, as Figure 4 shown in the figure, one side of the sound generating device 30 facing the edge of the interaction surface (i.e., one side along the transverse direction) has a sound outlet.

[0060] As an alternative embodiment of the present utility model, as Figure 4 shown in the figure, the back plate 100 further includes an inner connection portion 130. The inner connection portion 130 is arranged on the side of the inclined edge portion 120 facing the interaction surface, and a sound guiding bending hole 131 is arranged in the inner connection portion 130. One end of the sound guiding bending hole 131 is communicated with the sound outlet hole 121, and the other end of the sound guiding bending hole 131 is communicated with the sound outlet of the sound generating device 30.

[0061] As an alternative embodiment of the present utility model, as Figure 4As shown, the sound generating device 30 includes a sound generating module 31 and a sound cavity housing 32. The sound generating module 31 is disposed within the sound cavity housing 32, and the sound outlet is located on the sound cavity housing 32.

[0062] As an alternative embodiment of the present invention, as Figure 4 shown, the sound cavity housing 32 includes a front housing 321 and a rear housing 322. The front housing 321 is located on the side of the rear housing 322 facing the interaction surface, and the front housing 321 is connected to the rear housing 322 in an opposing manner. The side wall of the front housing 321 facing the edge of the interaction surface has a sound transmission hole 323. One end of the sound transmission hole 323 is in communication with the interior of the sound cavity housing 32, and the other end of the sound transmission hole 323 is the sound outlet.

[0063] As an alternative embodiment of the present invention, as Figure 4 shown, the wall-mounted interaction device further includes at least one waterproof and breathable membrane 40. The waterproof and breathable membrane 40 is disposed between the internal connection portion 130 and the sound generating device 30.

[0064] It can be understood that the waterproof and breathable membrane 40 can prevent liquid from flowing into the sound generating device 30 through the sound outlet hole 121, and at the same time has air permeability, thereby allowing the sound emitted by the sound generating device 30 to be normally conducted to the outside through the air.

[0065] As an alternative embodiment of the present invention, as Figures 6 to 9 shown, the opening of the sound outlet hole 121 on the outer surface of the hypotenuse portion 120 (in the present invention, the outer side refers to the side facing the outside of the housing 20, and correspondingly, the inner side refers to the side facing the inside of the housing 20) extends along the extension direction of the corresponding side edge of the mounting portion 110, that is, along the length direction of the hypotenuse portion 120. As Figure 9 shown, the length l of the sound outlet hole 121 along the length direction of the corresponding hypotenuse portion 120 is greater than its width w along the width direction of the corresponding hypotenuse portion 120.

[0066] To overcome the surface tension of rainwater and prevent rainwater from blocking the sound outlet hole 121, as a preferred embodiment of the present invention, as Figure 9 shown, the opening width w of the sound outlet hole 121 on the outer surface of the hypotenuse portion 120 is greater than or equal to 2.5 mm.

[0067] To improve the rain and snow prevention effect of the wall-mounted interaction device, as a preferred embodiment of the present invention, as Figure 7 shown, the inner wall of the sound outlet hole 121 located on the hypotenuse portion 120 extending longitudinally (that is, the sound outlet hole 121 on the first hypotenuse portion 120a or the second hypotenuse portion 120b) has a diversion inclined surface. The diversion inclined surface is located on the side of the sound outlet hole 121 facing longitudinally, and the distance d between the diversion inclined surface and the edge of the interaction surface on its corresponding side gradually decreases along the direction towards the outer opening of the sound outlet hole 121.

[0068] It is understandable that the side of the sound outlet hole 121 where the diversion inclined surface is provided is the side facing the ground when the wall-mounted interaction device is in use. In the embodiment of the present invention, the bottom of the sound outlet hole 121 located on the side is inclined outward, so that the rainwater entering the sound outlet hole 121 can flow out along the diversion inclined surface in time under the action of gravity, avoiding rainwater accumulation.

[0069] As an alternative embodiment of the present invention, as Figure 7 shown, the included angle between the diversion inclined surface and the extension direction of the corresponding hypotenuse part 120 is greater than or equal to 150°.

[0070] As an alternative embodiment of the present invention, as Figure 8 shown, a third hypotenuse part 120c extending in the transverse direction is further provided on one side of the housing 20 along the longitudinal direction. In the case where the sound outlet hole 121 is provided only on the first hypotenuse part 120a, the diversion inclined surface of the sound outlet hole 121 is located on the inner wall of the sound outlet hole 121 on the side facing the third hypotenuse part 120c, and the distance between the diversion inclined surface and the third hypotenuse part 120c gradually decreases along the direction towards the outer opening of the sound outlet hole 121, that is, the third hypotenuse part 120c is located at the bottom of the wall-mounted interaction device in the normal use state.

[0071] In some embodiments of the present invention, the sound outlet hole 121 may also be provided on the third hypotenuse part 120c.

[0072] As an alternative embodiment of the present invention, the outer side of the hypotenuse part 120 has an outer inclined surface, and there is a preset included angle between the outer inclined surface and the mounting part 110, that is, the outer surface of the hypotenuse part 120 can be a flat surface that is inclined relative to the mounting part 110.

[0073] As an alternative embodiment of the present invention, as Figure 3 、 Figure 4 shown, the outer side of the hypotenuse part 120 has an outwardly convex outer arc surface, that is, the outer surface of the hypotenuse part 120 is not a flat plane, but an arc surface with a certain curvature.

[0074] As Figure 3 、 Figure 4 shown, it is understandable that the inner surface of the hypotenuse part 120 can correspondingly be an inwardly concave inner arc surface to keep the thickness of the hypotenuse part 120 uniform.

[0075] As an alternative embodiment of the present invention, the thickness of the hypotenuse part 120 is less than or equal to 3 mm.

[0076] As an alternative embodiment of the present invention, as Figure 3 、 Figure 4As shown, the housing 20 further includes a middle frame 200. One end of the middle frame 200 is fixedly connected to the back plate 100, and the other end of the middle frame 200 has an interaction surface.

[0077] The embodiments of the present invention do not specifically limit how the wall-mounted interaction device is hung on the installation surface (wall surface), as long as the position of the wall-mounted interaction device can be ensured to be stable. For example, an adhesive can be provided on the side of the back plate 100 facing away from the interaction surface, and the wall-mounted interaction device can be adhered to the installation surface through the adhesiveness of the adhesive.

[0078] Alternatively, a hook structure can also be provided on the side of the back plate 100 facing away from the interaction surface, and the wall-mounted interaction device can be hung on structures such as holes, brackets, and hanging nets on the installation surface through the hook structure.

[0079] As an alternative embodiment of the present utility model, as Figure 3 、 Figure 4 、 Figures 6 to 9 shown, the wall-mounted interaction device further includes a mounting bracket 50. The mounting bracket 50 is stacked on the side of the mounting portion 110 facing away from the interaction surface, and the mounting bracket 50 is detachably and fixedly connected to the mounting portion 110.

[0080] It can be understood that the mounting bracket 50 is used to be fixedly connected to the installation surface (wall surface). When maintenance, repair, charging, or other operations need to be performed on the device, the device can be removed from the mounting bracket 50.

[0081] As an alternative embodiment of the present utility model, as Figure 8 shown, the mounting bracket 50 has a plurality of mounting holes that penetrate the mounting bracket 50 along the thickness direction of the mounting bracket 50. The mounting bracket 50 is used to be fixedly connected to the wall body 70 through fasteners that pass through the mounting holes and are nailed into the wall body 70, so as to hang the display device on the wall body 70.

[0082] As an alternative embodiment of the present utility model, the wall-mounted interaction device further includes a control component (not shown in the figure) disposed in the housing 20. The control component is used to drive the display panel 10 to display a picture.

[0083] It can be understood that the wall-mounted interaction device provided by the present utility model can also have other functional modules of the access control interaction device. For example, at least one interaction button can be provided on the interaction surface, and a visitor can press the interaction button to make a prompting sound on the device on the homeowner's side, thereby realizing the function of a smart doorbell.

[0084] As an alternative embodiment of the present utility model, as Figure 5 shown, at least one breathing light 61 is further provided on the interaction surface. The breathing light 61 can emit breathing light in the standby mode, so that a visitor can quickly find the wall-mounted interaction device in a dark environment, or play a prompting role in other modes.

[0085] As an alternative embodiment of the present utility model, the wall-mounted interactive device further includes at least one sound collection device (not shown in the figure) disposed in the housing 20. The sound collection device is used to collect external audio, generate a sound input signal and send the sound input signal to the control component, so as to realize the master-guest call intercom.

[0086] As an alternative embodiment of the present utility model, as Figure 5 shown, at least one camera 62 is further disposed on the interaction surface. The camera 62 is used to collect external images, generate an image input signal and send the image input signal to the control component, so that the visitor can see the picture information on the homeowner's side, enriching the master-guest interaction scenario.

[0087] The above is only the specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Those skilled in the art should understand that the present utility model includes but is not limited to the content described in the drawings and the above specific embodiments.
