[0006] A voice module is installed in the housing; and,

[0007] The noise reduction structure includes a plurality of noise reduction parts disposed on the mounting part. The end of each noise reduction part away from the mounting part is a contact end, which is used to contact a mating part on an electrical appliance. The contact ends of the plurality of noise reduction parts are arranged at intervals.

[0008] In some embodiments, the end of the silencing part used to connect with the mounting part is the mounting end, and the end face area of ​​the mounting end is larger than the end face area of ​​the contact end.

[0009] In some embodiments, the end face area of ​​the mounting end is A, and the end face area of ​​the contact end is a, where 0.15A < a < 0.35A; and / or,

[0010] The cross-sectional area of ​​the silencing portion gradually decreases from the mounting end to the contact end; and / or,

[0011] The end face of the contact terminal is frosted.

It should be understood that those skilled in the art will recognize that this application can be made without using these specific details. In other instances, well-known structures and processes are not described in detail to avoid obscuring the description of this application with unnecessary detail. Therefore, this application is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.

[0040] More and more appliances are now equipped with online voice functions, which can play music and answer questions. However, many appliances have poor noise isolation for the voice module. The noise generated during the operation of the appliance itself will be directly transmitted to the voice module, resulting in poor voice wake-up effect, affecting the recognition rate and user experience.

[0041] For this, please refer to Figures 1 to 6This application provides a voice box 50, which includes a box body 60, a voice module, and a noise reduction structure 70. The box body 60 is provided with a mounting part 61, which is used to cooperate with a mating part 11 on an electrical appliance 100. The voice module is mounted on the box body 60. The noise reduction structure 70 includes a plurality of noise reduction parts 71 disposed on the mounting part 61. The end of each noise reduction part 71 away from the mounting part 61 is a contact end 72, which is used to contact the mating part 11 on the electrical appliance 100. The contact ends 72 of the plurality of noise reduction parts 71 are arranged at intervals.

[0042] It should be noted that the specific implementation of the voice module is not limited, as long as it has the function of picking up sound. For example, the voice module can be a microphone or a pickup, etc., which is not limited here. The specific implementation of the mounting part 61 and the mating part 11 is not limited. The mounting part 61 can be a buckle 62, and the corresponding mating part 11 can be a buckle 62 or a socket. The voice box 50 is installed by the snap-fit ​​between the buckles 62 and the buckles 62 or the socket. The mounting part 61 can also be in the form of a snap-fit ​​64, and the corresponding mating part 11 is a plug-in slot. The voice box 50 can be installed by inserting the snap-fit ​​64 into the plug-in slot. Of course, the mounting part 61 and the mating part 11 can also be a screw hole and a screw post, etc., which is not limited here.

[0043] The contact ends 72 of the plurality of silencing parts 71 are arranged at intervals. The plurality of silencing parts 71 may only have their contact ends 72 arranged at intervals, while the other parts may be connected or spaced apart, which is not limited here.

[0044] It should be emphasized that although the main body of this embodiment is called voice box 50, it refers to a box containing a voice module. When the display box, control box, etc. of a home appliance contain a voice module, they should also be included in the protection scope of this application. If the silencing structure 70 is not provided, when the voice box 50 is installed on the appliance 100, the mounting part 61 and the mating part 11 use full-surface contact, resulting in a large contact area and easy noise transmission. However, by providing multiple silencing parts 71, the contact ends 72 of the multiple silencing parts 71 are arranged at intervals. That is, the gaps between the multiple contact ends 72, which were originally in direct contact with the mating part 11, are now gaps and no longer in contact, effectively reducing the contact area and blocking the transmission of noise.

[0045] The specific implementation of the electrical appliance 100 is not limited, as long as it has voice interaction functionality. For example, it can be an air conditioner, refrigerator, washing machine, etc., and is not limited here. The specific implementation of the noise-absorbing structure 70 is not limited. It can be a protrusion 711 directly protruding from the mounting part 61. In some embodiments, the noise-absorbing structure 70 can also include a silicone sleeve with multiple noise-absorbing parts 71 on its surface. By fitting the silicone sleeve onto the mounting part 61, the mounting part 61 can contact the mating part 11 through the noise-absorbing parts 71, etc., and is not limited here.

[0046] In this embodiment, by providing a noise-absorbing structure 70 on the mounting portion 61 of the housing 60, and the noise-absorbing structure 70 including multiple noise-absorbing portions 71, when the voice box 50 is installed on the electrical appliance 100, the original full-surface contact between the voice box 50 and the mating portion 11 is changed to small-end-face contact between the end faces of the multiple noise-absorbing portions 71, and the contact ends 72 of the multiple noise-absorbing portions 71 are spaced apart, which effectively reduces the contact area between the voice box 50 and the mating portion 11 on the electrical appliance 100, weakens the noise transmitted from the mating portion 11 to the voice module, and thus improves the noise isolation effect of the voice module.

[0047] It should be noted that the specific shape of the silencing part 71 is not limited. It can be cylindrical, conical, frustum, or pyramidal. It can be a regular shape or an irregular shape, etc., and is not limited here.

[0048] Please refer to the following: Figure 7 and Figure 8 In some embodiments, the end of the silencing part 71 that is connected to the mounting part 61 is a mounting end 73, and the end face area of ​​the mounting end 73 is larger than the end face area of ​​the contact end 72.

[0049] In the scheme of this embodiment, by increasing the area of ​​the mounting end 73, the contact area between the noise-absorbing part 71 and the mounting part 61 can be increased, making the noise-absorbing part 71 more stably supported by the mounting part 61. Meanwhile, by reducing the end face area of ​​the contact end 72, the contact area between the noise-absorbing part 71 and the mating part 11 can be effectively reduced, weakening the transmission of noise and reducing noise in the voice module.

[0050] Specifically, the size of the end face area of ​​the contact end 72 is not limited and can be any value. In some embodiments, the end face area of ​​the mounting end 73 is A, and the end face area of ​​the contact end 72 is a, where 0.15A < a < 0.35A.

[0051] With this configuration, the end face area of ​​the contact end 72 is greater than 0.15A, thus ensuring that the end face area of ​​the contact end 72 is not too small and guaranteeing the stability of the contact with the mating part 11. On the other hand, the end face area of ​​the contact end 72 is less than 0.35A, thus ensuring that the end face area of ​​the contact end 72 is not too large and guaranteeing the noise isolation effect of the voice module.

[0052] Furthermore, multiple experiments have shown that the vibration reduction and noise reduction effect is optimal when a = 0.25A, achieving a balance between stability and noise isolation.

[0053] The specific shape of the silencing part 71 is not limited, and the change in the cross-sectional area from the mounting end 73 to the contact surface is also not limited. It can be increased first and then decreased, or it can be continuously decreased, or it can be unchanged first and then decreased, etc., which are not limited here.

[0054] In one embodiment, the cross-sectional area of ​​the silencing part 71 gradually decreases from the mounting end 73 to the contact end 72. With this configuration, the area of ​​the silencing part 71 is gradually varied, and no mounting groove or protrusion 711 is formed between the mounting end 73 and the contact end 72. This effectively avoids stress concentration and improves the stability and strength of the silencing part 71.

[0055] It is understood that the end face of the contact end 72 is the contact surface that contacts the mating part 11, and its specific form is not limited. It can be a smooth surface, a frosted surface, etc., and is not limited here.

[0056] In one embodiment, the end face of the contact end 72 is provided with a frosted surface. With this configuration, the surface of the frosted surface has many small particles, which can further reduce the contact area with the mating part 11 and improve the noise reduction effect.

[0057] The number and form of the mounting parts 61 are not limited; there may be only one or multiple mounting parts. When there are multiple mounting parts 61, they may be installed in the same way, such as by snap-fit ​​or screw-fit. Alternatively, they may be installed in different ways. For example, some mounting parts 61 may be screw-fit parts on the housing 60, such as threaded holes 63 or screw posts; some mounting parts 61 may be snap-fit ​​parts on the housing, such as snap-fit ​​buckles 62 or card holders; and some mounting parts 61 may be plug-in parts on the housing, etc. There are no limitations on this. When there are multiple mounting parts 61, each mounting part 61 may be provided with the noise-reducing structure 70, or some mounting parts 61 may be provided with the noise-reducing structure 70 while others may not be provided with the mounting structure, etc. There are no limitations on this.

[0058] Please refer to this carefully. Figure 1 , Figure 4 , Figure 7 and Figure 9 In one embodiment, multiple mounting parts 61 are provided, each including multiple buckles 64, latches 62, and screw connections. The buckles 64 are located on one side of the housing 60, and the latches 62 are located on the housing 60, on the side opposite to the buckles 64. During installation, the buckles 64 are first inserted into the corresponding buckle 64 seats on the appliance 100 to position one side of the housing 60. Then, the housing 60 is pressed down to engage the latches 62 in their respective seats, completing the coarse positioning of the voice box 50. Finally, screws are used to connect the screw connections to the screw connections on the appliance 100, thus completing the assembly of the voice box 50. This configuration simplifies the installation process and ensures good stability after installation.

[0059] Please refer to this carefully. Figure 5 and Figure 8 In some embodiments, the mounting part 61 includes a buckle 62 disposed on the housing 60, and the noise reduction part 71 includes a protrusion 711 disposed on the buckle 62.

[0060] In the scheme of this embodiment, after the buckle 62 is snapped into the buckle 62 seat of the electrical appliance 100, the protrusion 711 on the buckle 62 will abut against the buckle 62 seat, thereby avoiding complete contact between the entire surface of the buckle 62 and the buckle 62 seat. The gap between the multiple protrusions 711 can effectively reduce the contact area with the buckle 62 seat and block the transmission of noise.

[0061] Please refer to this carefully. Figure 1 , Figure 4 , Figure 7 , Figure 9 and Figure 10 Of course, in some embodiments, the mounting part 61 is provided with a threaded hole 63, and the noise reduction part 71 includes a protrusion 711 disposed on the outer periphery of the threaded hole 63. With this configuration, after the threaded hole 63 of the mounting part 61 is aligned with the threaded hole 63 on the mating part 11 of the electrical appliance 100, the opening walls of the two threaded holes 63 are in contact with each other through the protrusion 711, which can effectively reduce the contact area between the opening walls and achieve noise reduction of the voice module.

[0062] Please refer to this carefully. Figure 6 In some embodiments, to enhance the strength of the mounting portion 61, a reinforcing rib 66 is provided on the mounting portion 61. Correspondingly, when the mounting portion 61 is installed with the mating portion 11, the reinforcing rib 66 and the mating portion 11 are in direct contact. Correspondingly, multiple grooves 65 can be provided at intervals along the reinforcing rib 66 to divide the reinforcing rib 66 into multiple noise-absorbing portions 71. By providing the grooves 65, the contact area between the reinforcing rib 66 and the mating portion 11 can be effectively reduced, thereby enhancing the strength of the mounting portion 61 while reducing noise transmission.

[0063] When multiple reinforcing ribs 66 are provided, some of the reinforcing ribs 66 may have the grooves 65, or all of the reinforcing ribs 66 may have the grooves 65; this is not limited here. The number of grooves 65 is not limited; it may be three, four, five, etc., and can be selected according to actual needs. The shape of the grooves 65 is also not limited; it may be a V-shaped groove or an arc-shaped groove; this is not limited here.

[0064] In one embodiment, the groove 65 is an arc-shaped groove, which allows sound to be repeatedly reflected within the arc-shaped groove, and the energy of the sound waves cancels each other out due to the phase difference.

[0065] Existing appliances 100 generally have a display box, which contains a display module to display the appliance's status information. For example, an air conditioner has a display box on its panel 10 to display the air conditioner's temperature, mode, and other status information. Another example is a washing machine, which also has a display box to display the operating mode, time, and other status information. The voice box 50 and the display box can be two separate components or integrated into one component. When integrated, it can effectively reduce costs and improve assembly efficiency.

[0066] Therefore, in one embodiment, the voice box 50 further includes a display module for displaying the status information of the home appliance. With this configuration, the voice box 50 is equipped with a display module, thereby integrating the existing voice box 50 and display box, improving production efficiency and reducing costs.

[0067] This utility model also proposes an electrical appliance 100, which includes a voice box 50. The specific structure of the voice box 50 is as described in the above embodiments. Since this electrical appliance 100 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0068] The specific implementation of the electrical appliance 100 is not limited, as long as it has voice interaction function. For example, it can be an air conditioner, refrigerator, washing machine, etc., and there is no limitation here.

[0069] Currently, the voice interaction function of air conditioners is gaining importance among users. Users control the temperature, fan speed, and other functions of the air conditioner through voice interaction. Therefore, the voice interaction function is of great importance to air conditioners. In some embodiments, the appliance 100 includes an air conditioner. In the solution of this embodiment, by applying the voice box 50 provided in this application to the air conditioner, especially when installed on the indoor unit of the air conditioner, the noise of the fan in the indoor unit of the air conditioner can be effectively reduced to reduce the interference of the voice module, thereby improving the voice interaction effect of the air conditioner.

[0070] In some embodiments, the electrical appliance 100 further includes a flexible pad disposed between the mating part 11 and the sound-absorbing part 71 of the voice box 50. With this arrangement, the flexible pad can play a role in shock absorption and sound absorption, thereby effectively reducing the propagation of sound.

[0071] Of course, in some embodiments, the sound-absorbing part 71 may be made of a flexible material, thereby improving the sound insulation effect of the sound-absorbing part 71.

[0072] The above provides a detailed description of the voice box and electrical appliances provided in the embodiments of this application. Specific examples have been used to illustrate the principles and implementation methods of this application. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of this application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this application. Therefore, the content of this specification should not be construed as a limitation of this application.
