[0002] With the rapid development of smart home technology, smart cooking speakers, as an important device in the kitchen, are gradually becoming a standard feature in modern family kitchens. Smart cooking speakers integrate functions such as voice assistants, recipe lookups, and cooking guidance, allowing users to obtain cooking information and control kitchen appliances through voice interaction. However, because the kitchen environment is usually quite noisy, and various noises are generated during cooking (such as the sounds of range hoods, chopping vegetables, and stir-frying), this places high demands on the audio output capabilities of smart cooking speakers.
[0003] In existing technologies, the design of smart cooking speakers is often limited by size. In order to maintain the compactness and aesthetics of the device, the speaker power is usually low, or the speaker's sound output structure is not designed reasonably enough, resulting in a low sound volume in the kitchen environment. Users have difficulty hearing voice prompts or music playback clearly, which affects the overall user experience. Utility Model Content

[0010] Furthermore, a support rib is provided inside the first sound hole, the end of which is connected to the inner wall of the first sound hole, and the support rib divides the first sound hole into at least two sound sub-holes;
[0011] The inner side of the dustproof net is connected to the supporting ribs.
[0012] Furthermore, the sound-generating device also includes a protective net, which surrounds the outside of the housing and is covered with a dustproof net.
[0013] Furthermore, the protective netting is made of metal.
[0014] Furthermore, the total area of the protective mesh covering all the sound-producing holes is greater than or equal to 25%-45% of the total area of the sound-producing holes.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0034] like Figures 1-5 As shown, the sound-generating device provided by this utility model includes: a housing 1, a horn 2, and a sealing ring 3, with the horn 2 and the sealing ring 3 both located inside the housing 1.
[0035] like Figure 4 As shown, the outer shell 1 can be cylindrical, prismatic, or similar in shape.
[0036] like Figure 3 As shown, the front side of the outer shell 1 can be a first mounting surface 4, and a first sound hole 5 penetrating the inside and outside of the outer shell 1 is provided on the first mounting surface 4. The shape of the first sound hole 5 can be circular, quadrilateral or other irregular shape.
[0037] The speaker 2 includes a second mounting surface 6, on which a second sound hole 7 is provided, and the sound waves generated by the speaker 2 are transmitted from the second sound hole 7.
[0038] The first sound hole 5 and the second sound hole 7 are aligned internally and externally. A sealing ring 3 is connected between the first mounting surface 4 and the second mounting surface 6. The inner side of the sealing ring 3 is attached to and connected to the second mounting surface 6, and the outer side of the sealing ring 3 is attached to and connected to the first mounting surface 4. The sealing ring 3 is connected to the first mounting surface 4 and the second mounting surface 6 respectively using adhesive. The sealing ring 3 is arranged around the circumferential outer side of the first sound hole 5 and the second sound hole 7, forming a sealed channel to reduce sound wave loss when passing through the first mounting surface 4 and the second mounting surface 6.
[0039] After the speaker 2 produces sound, the sound waves are transmitted outward along the channel formed by the second sound hole 7, the sealing ring 3, and the first sound hole 5. Because the sealing ring 3 connects the first mounting surface 4 and the second mounting surface 6, it prevents sound waves from leaking through other gaps between the first mounting surface 4 and the second mounting surface 6 during transmission to the first sound hole 5, thus maximizing the transmission of sound waves generated by the speaker 2 from the first sound hole 5, reducing sound wave loss, and increasing volume.
[0040] The sealing ring 3 can be made of shock-absorbing foam, which can absorb the vibration generated by the speaker 2 while forming an acoustic seal.
[0041] The horn 2 and the outer shell 1 are locked together by a threaded connection, which improves the connection strength and makes it difficult for relative movement to occur between the horn 2 and the outer shell 1.
[0042] like Figure 2 As shown, along a direction perpendicular to the first mounting surface 4, the projection of the second sound hole 7 onto the plane containing the first mounting surface 4 is located inside the first sound hole 5. This allows the sound waves emitted from the second sound hole 7 to be fully transmitted, increasing the volume.
[0043] To prevent dust and fumes from entering the product and the interior of the speaker 2, and to protect the performance of the speaker 2 and its internal circuit board, the sound-generating device includes a dustproof mesh 8, which covers the first sound hole 5 on the outside of the outer casing 1. The dustproof mesh 8 is connected to the outer casing 1 by adhesive.
[0044] Furthermore, such as Figure 3 As shown, a support rib 9 is provided inside the first sound hole 5, the end of which is connected to the inner wall of the first sound hole 5. The support rib 9 divides the first sound hole 5 into at least two sound sub-holes 10; the inner side of the dustproof net 8 is connected to the support rib 9.
[0045] In this embodiment, there is one supporting rib 9, which is set vertically, dividing the first sound hole 5 into two small sound sub-holes 10. The dustproof net 8 can be pasted to the first mounting surface 4 around its perimeter, and the middle part of the dustproof net 8 is pasted to the supporting rib 9. The setting of the supporting rib 9 can improve the overall strength of the first sound hole and increase the pasting area of the dustproof net 8, ensuring that the dustproof net 8 is pasted flat.
[0046] like Figure 1 and Figure 5 The sound-generating device also includes a protective net 11, which can be ring-shaped and surrounds the outside of the housing 1, covering the dustproof net 8 to prevent the dustproof net 8 from being scratched and falling off. The protective net 11 can be made of metal to improve heat dissipation.
[0047] The total area of the mesh covering all the sound holes 10 is greater than or equal to 25%-45%, for example 35%, and has a smaller impact on the volume.
[0048] The sound-generating device also includes a rechargeable battery connected to the speaker 2, and the device can be used in a portable manner and placed in a location without a power outlet.
[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
