Description

Technical Field

[0001] The utility model relates to the technical field of virtual robots, in particular to a bottom sound-generating structure of an intelligent virtual robot. Background Art

[0002] Virtual robots, also known as Bots and chatbots, are intelligent conversation systems based on natural language processing. They are intelligent robots that integrate multiple artificial technologies. With virtual robots, users can see flexible and changeable portraits, pictures, clothing, gestures, mouth shapes, and expressions at any time, which makes them more likely to be attracted and interact with them. Virtual robots can understand and answer users' questions. At the same time, in order to better handle problems, virtual robots can also seek help and consult users through multiple rounds of dialogue.

[0003] The existing sound-generating structures of virtual robots are all arranged in the shell, and are roughly divided into two types according to their appearance. The first type has only a small number of through holes or gaps for sound to pass through. This structure will prevent the sound from being effectively transmitted outward, causing the user to feel that the sound is muffled, or the sound volume will be different when standing in different directions. The second type is to set a large number of through holes around the sound-generating structure so that the sound can be transmitted in all directions. However, at this time, the sound is not clear because the sound is more divergent. If the sound volume is increased by increasing the power, the energy consumption will increase. Therefore, there is a need for a sound-generating structure that can transmit the sound in all directions and increase the sound volume. Utility Model Content

[0004] In view of this, the purpose of the utility model is to provide a bottom sound-emitting structure of an intelligent virtual robot. The eccentric setting of the base reflection hole and the axis of the speaker can make part of the sound reflected toward the periphery through the first reflection surface, and the other part of the sound reflected toward the periphery through the second reflection surface to achieve sound enhancement.

[0005] The technical solution adopted by the utility model to solve its technical problems is to provide a bottom sound-emitting structure of an intelligent virtual robot, including a shell and a bracket connected under the shell, the bracket including a base and a connecting frame connected between the base and the shell, a speaker facing the base is provided inside the shell, the shell is provided with a hole network covering the speaker, the upper surface of the base is provided with a first sound reflecting surface and a base reflecting hole, the inner side wall of the base reflecting hole is a second sound reflecting surface, the axis of the speaker is P, and the base reflecting hole is eccentrically arranged relative to P.

[0006] As a further improvement of the present invention, the housing and the base are both circular, the speaker is located at the center of the housing, and the reflection hole of the base is eccentrically arranged on the base.

[0007] As a further improvement of the present invention, the first sound reflecting surface is an inclined surface relative to the ground.

[0008] As a further improvement of the present invention, the second sound reflecting surface is a conical surface.

[0009] As a further improvement of the present invention, a third sound reflecting surface is further provided on the upper surface of the base, and the third sound reflecting surface is arranged around the first sound reflecting surface.

[0020] The technical solution of the utility model will be clearly and completely described below in conjunction with the accompanying drawings.

[0021] Reference Figure 1-4The utility model proposes a bottom sound-emitting structure of an intelligent virtual robot, comprising a shell 1 and a bracket 2 connected under the shell 1, the bracket 2 comprising a base 21 and a connecting frame 22 connected between the base 21 and the shell 1, a speaker 3 facing the base 21 is arranged inside the shell 1, the shell 1 is provided with a hole net 4 covering the speaker 3, the upper surface of the base 21 is provided with a first sound reflecting surface 211 and a base reflecting hole 212, the inner side wall of the base reflecting hole 212 is a second sound reflecting surface 2121, the axis of the speaker 3 is P, and the base reflecting hole 212 is eccentrically arranged relative to P; by covering the speaker 3 with the hole net 4, the speaker 3 can effectively spread sound to the surroundings to avoid muffled sound , eccentrically setting the base reflection hole 212 and the axis of the speaker 3 can make part of the sound reflected by the first reflection surface 211, and the other part of the sound reflected by the second reflection surface 2121. If the base reflection hole 212 is not eccentrically set, the sound from the center of the speaker facing downward will directly act on the desktop and vertically upward. Since the center of the hole network 4 is also approximately parallel to the desktop, this part of the sound will always propagate vertically up and down without effective utilization. The sound with a lower inclination near the center area must be repeatedly reflected before it can diverge to the surroundings. The eccentric setting of the present application can make the sound from the center of the speaker closer to the first reflection surface 211 and the second reflection surface 2121, reducing the time of repeated reflection.

[0022] Reference Figure 1-4 The housing 1 and the base 21 are both circular, the speaker 3 is located at the center of the housing 1, and the base reflection hole 212 is eccentrically set on the base 21; it is only necessary to eccentrically set the base reflection hole 212 on the base 21 to achieve an eccentric setting with the axis of the speaker 3, which is convenient for installation.

[0023] Reference Figure 4 It can be seen that the first sound reflecting surface 211 is an inclined surface relative to the ground, and the setting of the inclined surface can directly reflect the downward sound to the surroundings.

[0024] Reference Figure 3 and 4 It can be seen that the second sound reflecting surface 2121 is a conical surface.

[0025] Reference Figure 4 A third sound reflecting surface 213 is also provided on the upper surface of the base 21. The third sound reflecting surface 213 is arranged around the first sound reflecting surface 211. Since the sound will be dispersed in all directions after passing through the hole mesh 4, the third sound reflecting surface 213 is arranged around the first sound reflecting surface 211 to further disperse the sound.

[0026] Reference Figure 4 , the third sound reflecting surface 213 is a conical surface.

[0027] Reference Figure 2The surface of the mesh 4 is arc-shaped, and the speaker 3 protrudes from the lower surface of the shell 1; the speaker 3 protrudes from the shell 1 to make the sound completely divergent, avoiding the inner wall of the shell 1 blocking the sound, thereby making the sound muffled.

[0028] Reference Figure 2 A transition piece 6 is connected between the shell 1 and the mesh 4, and the surface of the transition piece 6 is arc-shaped. Since the mesh 4 has multiple through holes evenly distributed, setting the transition piece 6 to connect the mesh 4 can improve the connection stability of the mesh 4.

[0029] Reference Figure 3 A groove 61 is provided on the transition connector 6 , and a protrusion for inserting into the groove 61 is provided on the mesh 4 , so that the mesh 4 can be snapped onto the transition connector 6 .

[0030] The base reflection hole 212 is a through hole. When the user places the virtual robot on the desktop, the through hole can make the sound directed vertically downward be reflected upward again, and then reflected and diverged through the hole mesh 4.
