The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0042] With the popularity of smart homes, voice control has become the mainstream device control method. However, voice control requires better noise elimination to achieve better control effects. However, the arrangement of the speaker and microphone of the voice control device close to each other will affect the sound reception effect, and the sound emitted by the device itself may also be received by the microphone, thereby affecting the effect of voice recognition and control. In addition, since the airtight laminated structure of the microphone is composed of the microphone's flexible printed circuit (Flexible Printed Circuit, FPC), silicone sleeve, face shell, back glue, and TP glass sealing to form the sound inlet channel, and the airtightness of the face shell, back glue, and TP glass is often affected by the dimensional accuracy of the injection molding process of the face shell, the airtightness has an unstable problem. In response to this problem, the embodiment of the present application provides a voice control device that can have a higher voice control effect. The following embodiments will specifically illustrate the voice control device and voice device described in the present application.

[0043] In one embodiment, Figure 1As shown, a voice control device 10 is provided, which includes: a sound inlet channel composed of a glass cover 100, a back glue layer 101, a surface shell 102 and a flexible circuit board 103 stacked in sequence, the cross-sectional area of ​​the sound inlet hole 1011 of the back glue layer 101 is larger than the cross-sectional area of ​​the sound inlet hole 1021 of the surface shell 102; a glue dot area 1012 is provided in the sound inlet hole 1011 of the back glue layer 101, and the glue dot area 1012 is filled with glue.

[0044] Optionally, the glass cover 100 is provided with a sound inlet hole 1001, the adhesive layer 101 is provided with a sound inlet hole 1011, and the shell 102 is provided with a sound inlet hole 1021. Moreover, the sound inlet hole 1001 of the glass cover 100, the sound inlet hole 1011 of the adhesive layer 101, and the sound inlet hole 1021 of the shell 102 are through holes, and the stacked layers form a sound inlet channel of the voice control device. The cross-sectional area of ​​a section of the sound inlet hole 1001 of the glass cover 100 close to the adhesive layer 101 is the same as the cross-sectional area of ​​a section of the sound inlet hole 1021 of the shell 102 close to the adhesive layer 101. The cross-sectional area of ​​a section of the sound inlet hole 1011 of the back glue layer 101 close to the face shell 102 is larger than the cross-sectional area of ​​a section of the sound inlet hole 1021 of the face shell 102 close to the back glue 101, and a glue dot area 1012 is provided in the sound inlet hole 1011 of the back glue layer 101, and the glue dot area 1012 is filled with glue, that is, the glue dot area 1012 is an area for performing glue dot operation, in which the glue dot material is filled after the glue dot operation.

[0045] Optionally, the sound inlet holes on each component of the laminated structure in the above voice control device have the same contour shape, and the sound inlet holes on each component can be holes with a circular contour or holes of other shapes.

[0046] Optionally, the flexible circuit board FPC103 is used to identify and process voice signals entering from the sound inlet holes of the glass cover 100, the backing layer 101, and the surface shell 102 in sequence, and then perform voice control based on the identified and processed voice signals.

[0047] Optionally, the material of the glass cover is TP glass.

[0048] In the embodiment of the present application, the voice control device 10 may include one sound inlet channel, or multiple sound inlet channels, and each sound inlet channel may be assembled from top to bottom by a glass cover 100, a backing layer 101, a face shell 102, and a flexible circuit board FPC 103. Except for the sound inlet hole 1011 on the backing layer 101, the cross-sectional areas of the sound inlet holes on other components are the same, and the cross-sectional area of ​​the sound inlet hole 1011 on the backing layer 101 is larger than the cross-sectional area of ​​the sound inlet hole 1021 on the face shell 102. The redundant area of ​​the sound inlet hole 1011 of the backing layer 101 compared with the sound inlet hole 1021 of the face shell 102 is a glue spotting area, and glue spotting filling can be performed in the glue spotting area, that is, the sealing glue is filled in the glue spotting area, and the material of the sealing glue is different from the material of the backing glue.

[0049] It should be noted that, compared with the traditional technology, the cross-sectional area of ​​the sound inlet hole 1011 on the adhesive layer 101 is the same as the cross-sectional area of ​​the sound inlet hole 1021 on the face shell 102. Therefore, in actual manufacturing, the sound inlet hole 1011 on the adhesive layer 101 is easily affected by the process manufacturing accuracy, resulting in a deviation in the center position of the sound inlet hole 1011 on the adhesive layer 101. In this case, the sound inlet hole 1011 on the adhesive layer 101 will correspondingly block the sound inlet hole 1011 of the upper glass cover 100 and the sound inlet hole of the lower face shell 102, thereby affecting the sound intake effect of the upper glass cover 100 and the sound intake effect of the face shell 102. In the present application, when the cross-sectional area of ​​the sound inlet hole 1011 on the adhesive layer 101 is larger than the cross-sectional area of ​​the sound inlet hole 1021 on the face shell 102, the risk of the above-mentioned problem can be reduced.

[0050] The voice control device described in the above application embodiment includes: a sound inlet channel composed of a glass cover sheet, a backing glue layer, a face shell and a flexible circuit board stacked in sequence, the cross-sectional area of ​​the sound inlet hole of the backing glue layer is larger than the cross-sectional area of ​​the sound inlet hole of the face shell; a glue spot area is provided in the sound inlet hole of the backing glue layer, and the glue spot area is filled with glue. The voice control device achieves double airtightness sealing through the backing glue layer and the glue spot filled in the glue spot area on the backing glue layer, so that the airtightness of the voice control device is not easily affected by the dimensional accuracy of the face shell injection molding process, thereby improving the stability of the airtightness of the glass cover sheet and the face shell in the voice control device, thereby improving the voice control effect of the voice control device.

[0051] In one embodiment, Figure 2 As shown, the above-mentioned surface shell 102 is provided with a groove 1013 at the position of the above-mentioned glue spot area 1012, the concave direction of the groove 1013 is toward the surface shell 102, and the groove 1013 is filled with glue.

[0052] Among them, a groove 1013 is provided at a position where the sound inlet hole 1011 of the adhesive layer 101 is redundant compared to the sound inlet hole 1021 of the face shell 102, and the concave direction of the groove 1013 is toward the face shell 102. The capacity of the groove 1013 is related to the cross-sectional area of ​​the glue dispensing area. Specifically, the glue dispensing operation can be performed in the groove 1013. The shape of the groove 1013 is related to the shape of the sound inlet hole 1011 on the adhesive layer 101. For example, when the sound inlet hole 1011 on the adhesive layer 101 is a circular hole, the groove 1013 can be a circular ring-shaped groove. It should be noted that when a sound inlet hole 1011 is provided on the back glue layer 101, a groove 1013 can be provided at the glue spot area adjacent to the sound inlet hole 1011; when multiple sound inlet holes 1011 are provided on the back glue layer 101, corresponding grooves 1013 can be provided at the glue spot area adjacent to each sound inlet hole 1011; the glue spot in each groove 1013 and the back glue layer 101 together form an airtight double seal.

[0053] In the voice control device described in the above application embodiment, a groove is provided at the location of the glue dispensing area, that is, a space for a sealant water tank is reserved around the sound inlet hole of the face shell, which can prevent the glue dispensing material from flowing into the sound inlet hole of the face shell when dispensing in the glue dispensing area, thereby affecting the voice control effect of the voice control device. Therefore, the voice control effect of the voice control device can be improved by the design of the groove.

[0054] In one embodiment, the voice control device further includes a switch control panel. The sound inlet channel in any of the above embodiments is arranged on the switch control panel, and the position of the sound inlet hole on the glass cover of the switch control panel can also be designed, such as Figure 3 A schematic diagram of a switch control panel is shown, on which a glass cover 100 includes a switch window 1002, a button assembly 1003, at least one sound inlet hole 1001, and at least one sound outlet hole 1004; the sound inlet hole 1001 of the glass cover 100 is located on a first side 10013 of the switch window 1002 on the glass cover 100, and the sound outlet hole 1004 of the glass cover 100 is located on a second side 10014 of the switch window 1002 opposite to the first side.

[0055] The device described in the above embodiment can reduce the influence of the sound outlet on the sound receiving effect of the sound inlet by arranging the sound inlet and the sound outlet at the top and bottom (both sides) of the switch window on the glass cover so that the sound inlet and the sound outlet are relatively far away from each other, thereby reducing the influence of the sound outlet on the sound receiving effect of the sound inlet, thereby reducing the effect of voice recognition and control.

[0056] In one embodiment, the area where the second side 10014 of the glass cover is located includes a key assembly 1003, and the sound hole 1004 is located in the surrounding area of ​​the key assembly 1003. A gap 1005 is provided in the surrounding area of ​​the key assembly 1003, and the sound hole 1004 is located in the gap 1005. Optionally, the sound inlet 1001 can be a microphone port, and the sound outlet 1004 can be a speaker. In the above embodiment, by providing the sound outlet 1004 in the gap 1005, compared with the traditional sound outlet, the sound outlet 1004 described in the embodiment of the present application is located in the gap area around the key assembly 1003, which can effectively utilize the space on the glass cover 100 and reduce the influence of the sound outlet 1004 itself on the sound effect.

[0057] Optionally, a first sound inlet hole 10011 and a second sound inlet hole 10012 are provided in the area where the first side 10013 is located, and the distance between the first sound inlet hole 10011 and the second sound inlet hole 10012 is greater than a preset distance threshold, which means that the first sound inlet hole 10011 and the second sound inlet hole 10012 are separated by a certain distance, so that the mutual sound inlet channels can be prevented from being affected by interference.

[0058] Optional, Figure 1 The voice control device 10 shown further includes: an isolation layer 104 disposed between the face shell 102 and the flexible circuit board 103 ; wherein the cross-sectional area of ​​the sound inlet hole 1041 of the isolation layer 104 is the same as the cross-sectional area of ​​the sound inlet hole 1021 of the face shell 102 .

[0059] Optionally, the isolation layer 104 is made of silicone material or other elastic materials, for example, the isolation layer can be a silicone sleeve. The isolation layer 104 is used to isolate the face shell 102 from the flexible circuit board 103, and to seal the space between the face shell 102 and the flexible circuit board 103. Specifically, the cross-sectional area of ​​a section of the sound inlet hole 1041 of the isolation layer 104 close to the face shell 102 is the same as the cross-sectional area of ​​a section of the face shell 102 close to the isolation layer 104.

[0060] Optional, Figure 1 The voice control device 10 shown also includes: a clamping bracket 105; the clamping bracket 105 is arranged on the side of the flexible circuit board 103 away from the surface shell 102; wherein, the air tightness of the sound inlet holes on the above-mentioned glass cover 100, the back adhesive layer 101, and the surface shell 102 is achieved by pre-tightening the isolation layer 104 (silicone sleeve), and the clamping bracket 105 can provide a clamping force to the isolation layer 104 through a plurality of locking screws.

[0061] For example, based on the voice control device described in any of the above embodiments, a specific voice control device is provided, in which the microphone and the speaker are respectively located at the top and bottom of the switch window on the glass cover, and the speaker is located around the bottom button assembly on the glass cover, that is, compared with the traditional speaker, the speaker is located in the gap area around the button assembly, and two microphones can be provided at the top of the switch window, respectively located on the left and right sides of the switch window, and the speaker and the microphone are both airtightly treated as above. The structure of the voice control device can more effectively ensure the consistency of the airtightness of the microphone, and to a certain extent, it can avoid the noise generated by the self-echo to the sound reception of the voice control device, thereby improving the voice control effect. It should be noted that the above airtightness treatment includes: taking the sound inlet as a circular hole as an example, the diameter of the sound inlet of the back glue layer in the voice control device is larger than the diameter of the sound inlet of the shell. The purpose of this design is to reserve space for a sealant tank around the sound inlet of the shell, that is, through the back glue + point glue solution, the consistency of the airtightness of the microphone can be more effectively ensured.

[0062] The clamping bracket 105 can clamp the sound input channel (microphone) and keep the sound input channel (microphone) away from the internal cavity, thereby minimizing the noise interference from the sound output channel (speaker) from the inside, thereby improving the voice recognition and control effects of the voice control device.

[0063] In one embodiment, a voice device is provided, whose internal structure diagram can be as follows: Figure 4 The voice device includes the voice control device described in any one of the above embodiments.

For those skilled in the art, the present invention may have various deformations and changes. Any modification, improvement and equivalent substitution made within the concept and principle of the present invention should be included in the protection scope of the present invention.

[0065] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
