[0042] The present application provides a robot 100, which can be a sound box and can be used to emit audio.

[0043] In the embodiments of the present application, as shown in Figure 1 , Figure 2 , Figure 3 and Figure 5 , the robot 100 comprises:

[0044] a main body 1, which is provided with an assembly cavity 1a and a first sound outlet hole 1b in communication with the assembly cavity 1a;

[0045] Two driving wheels 2, two driving wheels 2 are installed on the opposite sides of the main body 1 respectively;

[0046] The first sound emitting module 3 is arranged in the assembly cavity 1a and corresponds to the first sound hole 1b; the first sound emitting module 3 has a first rear sound cavity 3a and a first through hole 3c communicating inside and outside the first rear sound cavity 3a; the first sound emitting module 3 has the function of playing low-frequency sound; and

[0047] The edgeless radiator 5 is arranged in the first rear sound cavity 3a and covers the first through hole 3c.

[0048] It can be understood that, compared with the traditional closed box design, in the process of sound emission of the first sound emitting module 3 in the embodiment, the air in the first rear sound cavity 3a will drive the edgeless radiator 5 to passively emit sound, and the passive vibration of the edgeless radiator 5 radiated to the first rear sound cavity 3a will affect the air in the first rear sound cavity 3a, achieving the purpose of adjusting the bass timbre of the first sound emitting module 3. The setting of the edgeless radiator 5 can expand the lower limit frequency of uniform playback of low frequency under the condition that the sound pressure does not decrease, increase the maximum power that the module can withstand, make the robot 100 more compliant, improve the low frequency playback effect, and make the bass more full.

[0049] The assembly cavity 1a is used to provide mounting space, the main body 1 is driven to move by the two driving wheels 2, and the mobility of the robot 100 is realized, the robot 100 does not need to be placed in a fixed position for use, the sound playback in multiple scenes is met, and better interactive experience is obtained. The assembly cavity 1a is used to provide mounting space, the first sound emitting module 3 is installed in the assembly cavity 1a, and since the main body 1 basically remains stationary during the movement of the robot 100, it can ensure that the sound waves emitted from the first sound hole 1b are more stable and the sound emission effect is better, and the edgeless radiator 5 optimizes the low frequency playback effect. The setting of the edgeless radiator 5 can expand the lower limit frequency of uniform playback of low frequency under the condition that the sound pressure does not decrease, increase the maximum power that the module can withstand, make the robot 100 more compliant, improve the low frequency playback effect, and make the bass more full.

[0050] In the embodiment, the first sound hole 1b includes a plurality of first sound holes, which can play a role in dust prevention and protection of the first sound emitting module 3.

[0051] In other embodiments, the first sound hole 1b can also be a hole.

[0052] It should be noted that in the embodiment, the first sound generating module 3 only needs to have the function of playing low-frequency sound, and is not limited to being a low-frequency loudspeaker. The first sound generating module 3 can be a low-frequency loudspeaker, a medium-low-frequency loudspeaker, or a full-frequency loudspeaker.

[0053] In an embodiment of the present application, as shown in Figure 1 、 Figure 2 、 Figure 3 and Figure 4 , the drive wheel 2 comprises:

[0054] a rotating assembly 21 provided with a receiving groove 21a;

[0055] a bearing 23 accommodated in the receiving groove 21a, the bearing 23 being connected with the rotating assembly 21;

[0056] a support base 22 connected with the bearing 23 to rotationally connect the rotating assembly 21 and the support base 22; the support base 22 is connected with the main body 1, and a second through hole 22a corresponding to the rimless radiator 5 is provided on the support base 22, the first through hole 3c and the second through hole 22a being in communication.

[0057] The passive vibration of the rimless radiator 5 can be radiated to the first rear sound cavity 3a and the receiving groove 21a.

[0058] It can be understood that, due to the limited space of the first rear sound cavity 3a, the effect of improving low-frequency playback is limited if the passive vibration radiation of the rimless radiator 5 is only radiated to the first rear sound cavity 3a. In order to obtain better low-frequency playback effect, it is necessary to expand the radiation range of the rimless radiator 5. Therefore, in the embodiment, by providing the second through hole 22a, the rimless radiator 5 can not only be radiated to the first rear sound cavity 3a but also be radiated to the receiving groove 21a through the second through hole 22a, thereby expanding the radiation range of the rimless radiator 5 and making the first sound generating module 3 obtain better low-frequency playback effect. The embodiment reasonably utilizes the space of the drive wheel 2 to provide space for sound wave transmission of the rimless radiator 5

[0059] In the embodiment, the support base 22 is connected with the main body 1. The rotating assembly 21 is connected with the support base 22 through the bearing 23 to realize the rotation of the rotating assembly 21. When the rotating assembly 21 rotates on the ground, the robot 100 can be driven to move. The bearing 23 can improve the stability of the rotating assembly 21 and reduce the friction and save energy. The bearing 23 is accommodated in the accommodating groove 21a, so that the rotating assembly 21 can wrap and hide the bearing 23, and the bearing 23 is protected. In addition, the rotating assembly 21 and the support base 22 are connected through the bearing 23, so that the assembly is convenient and the installation efficiency is improved and the assembly difficulty is reduced.

[0060] The driving wheel 2 further comprises a driving member 24, which is installed on the support base 22 and provides stable support for the driving member 24. The rotating assembly 21 can be driven to rotate by the driving member 24. In the embodiment, the driving member 24 is a motor.

[0061] The robot 100 of the application comprises two driving wheels 2, which are different from four wheels of a car. If the rotating assembly 21 and the support base 22 are not connected through the bearing 23, the rotating assembly 21 only rotates around the motor shaft, that is, rotates around a point, which is unstable. After the support base 22 and the rotating assembly 21 are connected through the bearing 23, the rotating assembly 21 can also rotate around the bearing 23, that is, rotates around a surface, so that the rotation of the rotating assembly 21 is more stable, and the surface connection of the bearing 23 is stronger than the point connection of the motor shaft.

[0062] In order to ensure the sound effect of the robot 100, the main body 1 should be kept as stable as possible when the robot 100 moves, which is different from a balance car in which a person stands in the middle. If the rotating assembly 21 is directly driven to rotate by the motor, the main body 1 is unstable. After the bearing 23 is arranged, the relative movement between the main body 1 and the rotating assembly 21 is reduced, so that the main body 1 is more stable.

[0063] In addition, the embodiment does not need to arrange a speed reduction gear between the driving member 24 and the rotating assembly 21, so that the design difficulty is reduced.

[0064] In an embodiment of the application, as shown in Figure 3 and Figure 4 The rotating assembly 21 comprises:

[0065] an outer shell 211, which is provided with the accommodating groove 21a; and

[0066] A transmission member 212 is arranged in the accommodating recess 21a and between the housing 211 and the support base 22; the transmission member 212 is connected with the bearing 23, and the transmission member 212 is detachably connected with the housing 211.

[0067] It can be understood that the transmission member 212 is connected with the bearing 23 to achieve the purpose that the transmission member 212 can rotate relative to the support base 22, and the rotation of the transmission member 212 can drive the rotation of the housing 211. In the embodiment, the housing 211 is provided with the accommodating recess 21a, and the transmission member 212 is arranged in the accommodating recess 21a, so that the transmission member 212 can be hidden, and the transmission member 212 and the bearing 23 can be protected from external foreign matters, and the appearance can be beautiful. The housing 211 is clamped with the transmission member 212, so that the housing 211 and the transmission member 212 can be conveniently detached and installed, the efficiency is improved, the difficulty is reduced, and the housing 211 or the transmission member 212 can be prevented from being damaged in the process of installation and detachment.

[0068] In other embodiments, the rotating assembly 21 is an integrated structure, that is, the housing 211 and the transmission member 212 are integrally formed and fixed and cannot be detached, that is, the transmission member 212 is not separately arranged.

[0069] The detachable connection of the transmission member 212 and the housing 211 relative to the integrated and fixed arrangement of the housing 211 and the transmission member 212 can make the appearance of the robot 100 more beautiful.

[0070] Specifically, if the housing 211 and the transmission member 212 are an integrated and fixed structure, the installation process of the robot 100 is as follows:

[0071] S1: First, the bearing 23 is assembled on the support base 22, and the bearing 23 and the support base 22 can be fixedly connected by using a first locking member, and the bearing 23 and the support base 22 can be further arranged in an interference fit;

[0072] S2: Then, the rotating assembly 21 is assembled with the bearing 23, and the bearing 23 and the rotating assembly 21 can be fixedly connected by using a second locking member, and the bearing 23 and the rotating assembly 21 can be further arranged in an interference fit; at this time, a driving wheel 2 is formed.

[0073] S3: Then, the support base 22 is connected with the main body 1, and the assembly is completed.

[0074] To conceal the gap between the drive wheel 2 and the main body 1, the support base 22 needs to be located within the receiving groove 21a of the rotating component 21. This means the rotating component 21 would be used to cover the gap between the support base 22 and the main body 1. However, this would make it inconvenient to use bolts to connect the support base 22 and the main body 1; a snap-fit ​​connection would be necessary, reducing the connection strength. Conversely, if bolts are used, the support base 22 cannot be located within the receiving groove 21a of the rotating component 21. This means the gap would not be covered by the rotating component 21, leaving it exposed. This would reduce the overall aesthetics of the robot 100, and compared to the case where the rotating component 21 is used to cover the gap, exposed gaps are more prone to attracting dust and other foreign objects.

[0075] When the transmission component 212 and the housing 211 are configured to be detachably connected, the installation process of the robot 100 is as follows:

[0076] S1: First, assemble the bearing 23 onto the support seat 22. The bearing 23 and the support seat 22 can be fixedly connected by the first locking member. Furthermore, the bearing 23 and the support seat 22 can be set as an interference fit.

[0077] S2: Then assemble the transmission component 212 with the bearing 23. The bearing 23 and the transmission component 212 can be fixedly connected by a second locking component. Furthermore, the bearing 23 and the transmission component 212 can be set as an interference fit.

[0078] S3: Then connect the support base 22 to the main body 1 with bolts;

[0079] S4: Then connect the outer shell 211 to the transmission component 212. The connection can be made by snap-fit, so as to connect the drive wheel 2 to the main body 1.

[0080] like Figure 4 As shown, since the outer shell 211 is connected to the transmission component 212 after the support base 22 is connected to the main body 1, the edge of the outer shell 211 can extend to the side of the support base 22 away from the transmission component 212. In other words, the outer shell 211 can cover the gap at the connection between the support base 22 and the main body 1. Therefore, compared with the embodiment without setting a separate transmission component 212, setting the transmission component 212 can ensure the connection strength between the support base 22 and the main body 1 (i.e., the two can be connected by bolts), and can also ensure the aesthetics of the support base 22 and the main body 1 (i.e., the gap at the connection between the two can be covered).

[0081] In one embodiment of the present invention, the outer shell 211 and the support base 22 are spaced apart to form a sound outlet gap.

[0082] It can be understood that the sound outlet gap formed by the shell 211 and the support base 22 being spaced apart can further expand the radiation range of the edgeless radiator 5, and the passive sound emission of the edgeless radiator 5 is propagated to the accommodation groove 21a through the second through hole 22a, and then is propagated to the outside of the robot 100 through the sound outlet gap.

[0083] In an embodiment of the present application, the shell 211 is provided with a third sound outlet hole 2b, the third sound outlet hole 2b is in communication with the second through hole 22a through the accommodation groove 21a, and the third sound outlet hole 2b is arranged close to the second through hole 22a.

[0084] In the embodiment, the support base 22 is arranged in the accommodation groove 21a and close to the groove opening of the accommodation groove 21a. The periphery of the shell 211 extends to the side of the support base 22 facing the main body 1 to be sleeved on the main body 1, so as to eliminate the gap between the driving wheel 2 and the main body 1. In order to ensure that the passive sound emission of the edgeless radiator 5 can be propagated to the outside of the robot 100, the third sound outlet hole 2b in communication with the accommodation groove 21a can be arranged on the shell 211. The passive sound emission of the edgeless radiator 5 is propagated to the accommodation groove 21a through the second through hole 22a, and then is propagated to the outside of the robot 100 through the third sound outlet hole 2b. The embodiment can avoid the gap between the driving wheel 2 and the main body 1, and can ensure better low-frequency playback effect.

[0085] In an embodiment of the present application, as shown in Figure 1 , Figure 3 and Figure 4 , the third sound outlet hole 2b is arranged along the circumference of the shell 211. It can be understood that, since the driving wheel 2 is rotatable relative to the main body 1, when the driving wheel 2 rotates, the arrangement of the third sound outlet hole 2b along the circumference of the shell 211 can make the third sound outlet hole 2b always correspond to the second through hole 22a, so as to ensure that the sound emission effect of the edgeless radiator 5 can be transmitted to the outside.

[0086] In some embodiments, the third sound outlet hole 2b is a long strip-shaped arc-shaped hole formed along the circumference of the shell 211, and a connecting rib is arranged in the arc-shaped hole to ensure the integrity of the shell 211.

[0087] In the embodiment, the number of the third sound outlet holes 2b is multiple groups, and the multiple groups of third sound outlet holes 2b are arranged along the circumference of the shell 211. The driving wheel 2 is provided with multiple groups of the third sound outlet holes 2b, and the multiple groups of the first sound outlet holes 1b are arranged along the circumference of the driving wheel 2, so that the third sound outlet hole 2b is always corresponding to the no-rim radiator 5 during the rotation of the driving wheel 2. Each group of the third sound outlet holes 2b includes multiple third sound outlet holes, which can prevent dust and protect the no-rim radiator 5. Compared with the long strip-shaped arc-shaped hole, the multiple third sound outlet holes can ensure the strength of the shell 211. The robot 100 is placed on the ground, whether it is stationary or running, and is supported by the shell 211. Therefore, the design that can ensure the strength of the shell 211 is preferred.

[0088] In an embodiment of the present application, as shown in Figure 2 、 Figure 3 and Figure 5 , the first sound generation module 3 includes:

[0089] The first shell 31 is arranged in the assembly cavity 1a, and is provided with the first rear sound cavity 3a and the first through hole 3c. The first shell 31 is also provided with a first front sound cavity 3b and a first mounting hole communicating the first front sound cavity 3b and the first rear sound cavity 3a. The first front sound cavity 3b communicates with the first sound outlet hole 1b.

[0090] The first loudspeaker 32 is arranged at the first mounting hole.

[0091] In the embodiment, the first shell 31 abuts against the cavity wall of the assembly cavity 1a, so that the first front sound cavity 3b, the first sound outlet hole 1b and the rest of the first shell 31 are all sealed, which can prevent airflow crosstalk and form a standing wave. After the first loudspeaker 32 is installed at the first mounting hole, the first rear sound cavity 3a is sealed, which can prevent the formation of sound short circuit and improve the maximum power of the first loudspeaker 32 in the undistorted state.

[0092] In an embodiment of the present application, the side of the support seat 22 facing the assembly cavity 1a is provided with a first positioning boss 221, and the first positioning boss 221 is provided with the second through hole 22a.

[0093] The first shell 31 is provided with a second positioning boss 311, and the second positioning boss 311 is provided with the first through hole 3c. The second positioning boss 311 abuts against the first positioning boss 221.

[0094] It can be understood that, through the setting of the first positioning boss 221 and the second positioning boss 311, the positioning and installation of the first sound production module 3 and the support seat 22 can be facilitated. After the first positioning boss 221 and the second positioning boss 311 abut, the sound cavity is formed by the abutment of the sound radiation element 5, the hole wall of the first through hole 3c and the hole wall of the second through hole 22a. The sound cavity is separately arranged with the first rear sound cavity 3a and the assembly cavity 1a, that is, the first sound cavity is sealed except the second through hole 22a, which can prevent airflow interference and form a standing wave. The sound radiation element 5 is arranged opposite to the second through hole 22a, and the sound radiation element 5 is passively vibrated at the first through hole 3c, which can drive the air in the sound cavity to obtain better acoustic effect.

[0095] In the embodiment, the first sealing gasket is arranged between the first positioning boss 221 and the second positioning boss 311.

[0096] In an embodiment of the present application, as shown in Figure 2 , Figure 3 and Figure 5 , the number of the sound radiation elements 5 is two, each of the support seats 22 is provided with the second through hole 22a, and the first sound production module 3 is provided with the first through hole 3c corresponding to the two second through holes 22a on opposite sides, and each of the first through holes 3c is covered with one of the sound radiation elements 5.

[0097] It can be understood that, corresponding to the two drive wheels 2, two sound radiation elements 5 are arranged, which can further reduce the low-frequency playback cutoff frequency of the first sound production module 3, and at the same time, the maximum power of the first sound production module 3 under no distortion is improved. In addition, the third sound hole 2b is arranged on the two drive wheels 2, which can beautify the appearance of the robot 100, and also can obtain better sound quality effect.

[0098] In an embodiment of the present application, as shown in Figure 1 , Figure 2 , Figure 3 and Figure 4 , the main body 1 is further provided with a second sound hole 1c communicating with the assembly cavity 1a, and the robot 100 further comprises a second sound production module 4, and the second sound production module 4 is arranged corresponding to the second sound hole 1c.

[0099] In this embodiment, the first sound-emitting module 3 is used to reproduce low-frequency sounds, and the second sound-emitting module 4 is used to reproduce mid-to-high-frequency sounds. It can be understood that the first sound-emitting module 3, used to reproduce low-frequency sounds, emits sound waves from the first sound outlet 1b. The first sound-emitting module 3 focuses on reproducing bass frequencies and does not need to simultaneously reproduce mid-to-high frequencies, allowing the user to obtain a better low-frequency reproduction effect. The second sound-emitting module 4, used to reproduce mid-to-high-frequency sounds, emits sound waves from the second sound outlet 1c. The second sound-emitting module 4 focuses on reproducing mid-to-high frequencies, making mid-to-high-frequency reproduction smoother and more natural. This embodiment uses a frequency-separated design for low-frequency and mid-to-high-frequency reproduction, which can improve the low-frequency reproduction effect while ensuring mid-to-high-frequency reproduction, thereby improving the sound quality of the robot 100.

[0100] In this embodiment, the first sound-emitting module 3 is a low-frequency speaker module, and the second sound-emitting module 4 can be a mid-high frequency speaker module or a full-range speaker module. Using a full-range speaker module can take into account the reproduction of mid-high frequencies. The mid-high frequency reproduction of the full-range speaker module has better connection and the reproduction effect is smoother and more natural.

[0101] In another embodiment, the first sound-emitting module 3 is used to reproduce low-to-mid-frequency sounds, and the second sound-emitting module 4 is used to reproduce high-frequency sounds. By placing the passive radiator 5 in the first sound-emitting module 3, the low-frequency reproduction effect of the robot 100 can be optimized. It is understood that by placing the passive radiator 5 in the first sound-emitting module 3, the low-frequency reproduction effect of the first sound-emitting module 3 can be improved. In this embodiment, the first sound-emitting module 3 is a low-to-mid-frequency speaker module, and the second sound-emitting module 4 is a high-frequency speaker module. When the second sound-emitting module 4 is a high-frequency speaker module, the second rear acoustic cavity 4a may not be provided. This embodiment uses a frequency division design for low-to-mid-frequency reproduction and high-frequency reproduction, which can improve the low-frequency reproduction effect while ensuring the reproduction of mid-to-high frequencies, thereby improving the sound quality of the robot 100.

[0102] Specifically, such as Figure 2 As shown, the second sound-emitting module 4 is a mid-to-high-range speaker or a full-range speaker, and the second sound-emitting module 4 includes:

[0103] A second housing 41 is disposed within the assembly cavity 1a. The second housing 41 includes a second rear acoustic cavity 4a, a second front acoustic cavity 4b, and a second mounting hole connecting the second front acoustic cavity 4b and the second rear acoustic cavity 4a. The second front acoustic cavity 4b communicates with the second sound outlet 1c.

[0104] Second speaker 42; the second speaker 42 is disposed at the second mounting hole.

[0105] In the embodiment, the second shell 41 abuts against the cavity wall of the assembly cavity 1a, so that the second front sound cavity 4b is sealed at the second sound hole and other places, and airflow interference to form a standing wave can be prevented. After the second speaker 42 is installed at the second mounting hole, the second rear sound cavity 4a is sealed, sound short circuit can be prevented, and the maximum power of the second speaker 42 in a non-distortion state is improved.

[0106] In other embodiments, when the second sound production module 4 is a high-frequency speaker, the second shell 41 can only be provided with the second front sound cavity 4b, and the second rear sound cavity 4a is not provided, and the second speaker 42 is connected to the second shell 41.

[0107] In an embodiment of the present application, as shown in Figure 2 The second speaker 42 is arranged opposite to the second sound hole 1c.

[0108] It can be understood that the second speaker 42 is arranged opposite to the second sound hole 1c, which can effectively avoid the problem of high-frequency loss caused by strong high-frequency directivity.

[0109] In the embodiment, as shown in Figure 2 The main body 1 is in a cylindrical shape, and the assembly cavity 1a is further provided with a MIC module 6, a battery module 7, a balance module 8, and a counterweight module 9, etc. The MIC module 6 is used to place a mic and a volume control button, and the main body 1 is provided with a button hole for penetrating the button. Obviously, the MIC module 6 is arranged close to the cavity wall of the assembly cavity 1a. In order to facilitate operation, the button hole is arranged at the middle part and the upper part of the middle part of the main body 1. The battery module 7 is used to store power and also serves as a counterweight. Obviously, the battery module 7 also needs to be arranged close to the cavity wall of the assembly cavity 1a. The counterweight module 9 is arranged close to the battery module 7, so that the robot is in a stable state during movement, and can help the battery module 7 dissipate heat. In order to ensure the balance stability of the main body 1, the battery module 7 and the counterweight module 9 are arranged at the lower part of the assembly cavity 1a. The balance module 8 is provided with an algorithm to maintain the balance of the trolley. In order to make the directivity of the first sound hole 1b and the second sound hole 1c better, and facilitate the user to receive audio information, the first sound hole 1b and the second sound hole 1c should also be arranged at the middle part or the upper part of the middle part of the main body 1. In order to ensure the balance stability of the main body 1, the MIC module 6 and the second sound hole module are arranged at the middle part of the main body 1. In order to balance and facilitate wiring, the balance module 8 is arranged adjacent to the MIC module 6. Specifically, the MIC module 6 and the balance module 8 are arranged vertically. After the arrangement of the above modules is completed, the first sound hole 1b is arranged at the top of the main body 1, and the third sound hole 2b is arranged on the driving wheel 2, so that a larger volume of the first rear sound cavity 3a can be obtained under the same volume of the mounting cavity, and better acoustic effect can be obtained.

[0110] The above merely describes optional embodiments of the present application, and does not limit the patent scope of the present application. Any equivalent structural transformation, direct / indirect application in other related technical fields, or the like, made under the creative concept of the present application, using the content of the present application specification and drawings, are included in the patent protection scope of the present application.
