Description

Technical Field

[0001] The utility model specifically relates to an intelligent speaker. Background Art

[0002] In the field of modern smart home, smart speakers are an important part of home entertainment and information interaction. Usually, they are speakers that can make sounds. Their sound quality, design aesthetics and intelligence are increasingly becoming the focus of consumers. Traditional smart speaker designs often focus on the optimization of audio output and the integration of intelligent functions, while the consideration of sound propagation direction and spatial diffusion effect is relatively limited. For example, the inventor previously applied for CN202222520545.8, a smart speaker installation structure.

[0003] It can be seen that in the prior art, since the sound output direction of the speaker must be toward one side, the speaker of the virtual robot directly faces one side to diffuse the sound. Although this design can achieve basic sound coverage, it is difficult to achieve uniform sound propagation in different directions. The strong impact in a single direction causes the final sound effect to be concentrated and strong. In a specific usage environment, the product's orientation angle needs to be adjusted to obtain a better experience. If the user moves around the product, it is difficult to obtain a good sound experience.

[0004] Therefore, there is an urgent need for a new type of smart speaker design, which should be able to effectively guide and optimize the sound propagation path, reduce the impact of environmental factors on sound quality, and at the same time achieve structural innovation, taking into account both aesthetics and functionality to meet the diversified needs of modern families for smart speakers. Based on such a technical background, the present invention proposes a smart speaker with an integrated unique flow guide structure, which aims to improve the directional propagation and spatial diffusion of sound through carefully designed mounting frames, flow guide covers, flow guide parts and other components, and also enhance the overall design sense and environmental adaptability of the product, thereby providing users with a richer and higher-quality audio experience.

[0005] The utility model is produced based on the above-mentioned shortcomings. Utility Model Content

[0028] like Figures 1 to 5 As shown, the present embodiment provides an intelligent speaker, comprising a base 1 and a host 2 connected to the upper side thereof, a mounting frame 21 is provided at the bottom of the host 2, a sound-emitting element 22 with a sound-emitting direction facing downward is connected to the mounting frame 21, that is, the sound-emitting element 22 is a speaker and the sound-emitting direction of the speaker is facing downward, a sound inlet 211 corresponding to the sound-emitting element 22 is provided in the middle of the mounting frame 21, a guide cover 23 surrounding the sound inlet 211 is connected to the lower side of the mounting frame, and the sound of the speaker can enter the inside of the guide cover 23 from top to bottom, the upper side of the guide cover 23 is open and gradually bends inward from top to bottom, a guide member 24 is provided at the bottom of the inner side of the guide cover 23, a guide portion 241 is provided in the middle of the guide member 24, the guide portion 241 is convex upward and the height decreases from the middle to the surroundings, preferably, the guide portion 241 adopts a curved cone, and the side of the cone is formed by a generatrix composed of curves, such as Figure 2 As shown in FIG. 1 , the curvature of the air guide portion 241 gradually decreases from the center to the periphery. The air guide cover 23 is provided with a plurality of sound outlet holes 231, such as Figure 2 The sound wave propagation direction shown is P, so that the sound waves emitted by the speaker propagate downward inside the air guide 23. At this time, the inner wall of the air guide 23 that gradually converges inward can effectively control the diffusion path of the sound, reduce the direct reflection of the sound between its inner walls, thereby improving the clarity and directionality of the sound, so that the sound waves can be concentrated and propagated to the air guide 24. Through the guide portion 241 of the air guide 24, the sound is effectively refracted and diffused inside the air guide 23, and finally released evenly and directionally through the sound outlet 231, optimizing the flow direction of the sound, helping to form a more uniform sound field in a specific area, and improving the listening experience, so that the sound processed by the air guide is propagated in a more dispersed and smooth manner, reducing the strong impact in a single direction, and is suitable for application environments that require broad and soft sound coverage.

[0029] As a preference, Figures 2 to 5As shown, the mounting frame 21 is provided with a surrounding plate 212 surrounding the sound-emitting element 22, and the surrounding plate 212 is provided with a phase guide hole 213 connected to the outside, and the air guide 24 has a flat plate portion 242 surrounding the air guide portion 241 and having a flat surface. The above structure has significant effects. First, the phase guide hole 213 allows the air inside the speaker to exchange with the external environment, which is crucial for the improvement and expansion of low-frequency response. When the speaker unit vibrates, these holes can help to discharge the air pressure fluctuations inside the box, enhance the bass effect and reduce distortion; second, the sound is reflected by the flat plate portion 242 and propagates outward through the phase guide hole 213 above. The phase guide hole 213 serves as an output channel for sound waves and is superimposed on the sound radiated forward by the speaker unit, especially in the low-frequency band, to improve the low-frequency performance, effectively increase the volume and depth of the bass, so that the speaker can be more efficient in a specific low-frequency range and provide a flatter frequency response curve.

The guide plate 12 is gradually bent upward from the middle to the surroundings, so that the sound propagated from the sound outlet 231, the downward sound waves are refracted by the guide plate 12 and propagate upward and outward again, as shown in FIG. Figure 2 The direction of sound wave propagation is shown as P.

[0032] As a further improvement, Figures 2 to 5As shown, the bottom support plate 11 is connected to a support seat 13, the bottom of the support seat 13 is connected to the bottom support plate 11 and the top of the support seat 13 is connected to the air guide cover 23, a receiving groove 131 is provided in the middle of the support seat 13, a light-emitting element 14 is provided in the receiving groove 131 of the support seat 13, the support seat 13 is an integrated structure made of a light-transmitting material or the support seat 13 is partially made of a light-transmitting material, and the receiving groove 131 in the middle of the support seat 13 is specially designed for installing the light-emitting element 14, which is not only beautiful, but also can provide auxiliary lighting or atmosphere creation effect.
