Description

Technical Field

[0001] The present invention relates to the technical field of speaker equipment, and in particular to an intelligent speaker and a control method thereof. Background Art

[0002] A speaker refers to a device that can convert audio signals into sound. In layman's terms, it refers to a speaker main box or subwoofer box with a built-in power amplifier, which amplifies the audio signal and then plays back the sound through the speaker itself, making the sound louder.

[0003] The speaker is the terminal of the entire audio system. Its function is to convert audio electrical energy into corresponding sound energy and radiate it into space. It is an extremely important component of the audio system and is responsible for converting electrical signals into sound signals for direct listening by human ears.

[0004] In the existing technology, the storage structure used in the smart speaker is hollow inside. When the microphone is placed in the storage structure, it will fall directly from the entrance to the bottom of the storage structure. During this process, the microphone almost performs free fall motion. When the microphone reaches the bottom of the storage structure, the microphone will hit the bottom of the storage structure, which will not only generate loud noise, but also cause damage to the microphone or the storage structure due to the excessive impact force. Summary of the invention

The abutting end is disposed on the sliding seat. The inlet end, the first blocking block, the second blocking block, the third blocking block, and the abutting end are sequentially and spaced apart in the accommodating space.

[0012] Further, it is set that the distance between the inlet end and the first blocking block is L1, the distance between the first blocking block and the second blocking block is L2, the distance between the second blocking block and the third blocking block is L3, and the distance between the third blocking block and the abutting end is L4, satisfying the following relational expression: L1 = 3 * L2 = 5 * L3 = 7 * L4.

[0013] Further, the first blocking block includes a first arc surface and a second arc surface. The first arc surface is connected to the second arc surface. The second arc surface is disposed at an end facing away from the inner wall of the storage cylinder.

[0014] Further, the first blocking block further includes a deformation groove, which is disposed on a side facing away from the first arc surface. The structures of the second blocking block and the third blocking block are the same as that of the first blocking block.

[0015] Further, the extension length of the first blocking block on the inner wall of the accommodating space is H1, the extension length of the second blocking block on the inner wall of the accommodating space is H2, and the extension length of the third blocking block on the inner wall of the accommodating space is H3. Among them, the values of H1, H2, and H3 gradually increase.

[0016] Further, the accommodating space includes an inlet groove and a placement groove. The inlet groove and the placement groove are communicated. The inlet end is disposed at an end of the inlet groove facing away from the placement groove. And in the direction of the inlet end towards the placement groove, the aperture of the inlet groove gradually decreases. The blocking portion is disposed in the placement groove, and a sealing ring is provided on the inlet groove.

[0017] A control method for a smart speaker, used to control the above smart speaker, the method includes:

[0018] When the microphone is placed therein, control the first electromagnet and the mating magnet to turn on and the second electromagnet to turn off, so as to generate a first repulsive force between the first electromagnet and the mating magnet, and the first repulsive force is less than the gravity of the microphone itself;

[0021] Implementing the embodiments of the present invention will have the following beneficial effects:

[0022] In one embodiment, for the smart speaker of the present application, since a blocking portion and a first electromagnet are provided in the storage assembly, and a mating magnet cooperating with the first electromagnet is provided on the microphone, when the microphone falls from the accommodation space, on the one hand, the blocking portion is used to reduce the falling speed of the microphone, and on the other hand, the repulsive force generated by the first electromagnet and the mating magnet is used to further slow down the falling speed of the microphone, thereby overcoming the technical problems that the existing smart speaker storage structure will generate relatively large noise when storing the microphone and will also cause damage to the microphone or the storage structure due to excessive impact force;

[0023] In another embodiment, the second elastic member is arranged as a cylindrical helical spring, and the first elastic member is arranged as a conical helical spring. The characteristic curve of the conical helical spring is non-linear and the stiffness gradually increases, while the characteristic curve of the cylindrical helical spring is linear. That is to say, when the microphone just contacts the buffer seat member, the cylindrical helical spring is subjected to a greater force, and when the microphone compresses the buffer seat member to a certain extent, the conical helical spring is subjected to a greater force. Thus, the first elastic member and the second elastic member are used alternately, and further the service life of the buffer seat member can be prolonged;

[0038] Please refer to Figures 1-7, an embodiment of the present invention provides an intelligent speaker 100, which includes a speaker main body 110 and a storage component 120. The storage component 120 includes a storage cylinder 121 and a buffer seat component 122. The storage cylinder 121 forms a receiving space 1211 for placing a microphone 200. A blocking portion 1212 is provided in the receiving space 1211. The buffer seat component 122 includes a base 1221, a sliding seat 1222, a first elastic member 1223, a second elastic member 1224, and a first electromagnet 1225. The storage cylinder 121 is connected to the base 1221. The sliding seat 1222 is slidably connected to the base 1221. Both ends of the first elastic member 1223 and the second elastic member 1224 abut between the base 1221 and the sliding seat 1222. The second elastic member 1224 is nested inside the first elastic member 1223. The first electromagnet 1225 is connected to the sliding seat 1222 and is provided on the side facing away from the base 1221. The microphone 200 is provided with a mating magnet 210 that cooperates with the first electromagnet 1225 to generate a repulsive force between the first electromagnet 1225 and the mating magnet 210. Exemplarily, the overall shape of the receiving space 1211 is cylindrical for placing the microphone 200. The speaker main body 110 includes a housing 111 and a speaker 112. The speaker 112 is installed inside the housing 111, and a cover body 113 rotatably connected to the housing 111 is provided on the housing 111. The function of the cover body 113 is to cover the receiving space 1211 to protect the microphone 200. The second elastic member 1224 is provided as a cylindrical helical spring, and the first elastic member 1223 is provided as a conical helical spring. Both the first electromagnet 1225 and the mating magnet 210 are electromagnets, and the magnitude of the magnetic force is adjusted by the on / off of the current and the magnitude of the current. The first electromagnet 1225 is integrally circular ring-shaped.

[0039] Please refer to Figure 3 , Figure 4 , Figure 5 , in this embodiment, since the blocking portion 1212 and the first electromagnet 1225 are provided in the storage component 120 of the intelligent speaker 100 of the present application, and the mating magnet 210 that cooperates with the first electromagnet 1225 is provided on the microphone 200, when the microphone 200 falls from the receiving space 1211, on the one hand, the blocking portion 1212 is used to reduce the falling speed of the microphone 200, and on the other hand, the repulsive force generated by the first electromagnet 1225 and the mating magnet 210 is used to further slow down the falling speed of the microphone 200, thereby overcoming the technical problems that the existing storage structure of the intelligent speaker 100 will generate a large noise when storing the microphone 200, and will also cause damage to the microphone 200 or the storage structure due to excessive impact force.

[0040] Please refer to Figure 3 , Figure 4 , Figure 5, in this embodiment, the second elastic member 1224 is set as a cylindrical helical spring, and the first elastic member 1223 is set as a conical helical spring. The characteristic curve of the conical helical spring is non-linear and the stiffness gradually increases, while the characteristic curve of the cylindrical helical spring is linear. That is to say, when the microphone 200 just contacts the buffer seat member 122, the cylindrical helical spring is subjected to a greater force. When the microphone 200 compresses the buffer seat member 122 to a certain extent, the conical helical spring is subjected to a greater force. As a result, the first elastic member 1223 and the second elastic member 1224 are used alternately, which can further extend the service life of the buffer seat member 122.

[0041] Please refer to Figure 3 , Figure 4 , Figure 5 , in a possible implementation manner, a first conical surface 1225A is formed on the side of the first electromagnet 1225 facing away from the sliding seat 1222, and a second conical surface 220 is formed on the microphone 200 to cooperate with the first conical surface 1225A. Exemplarily, the first conical surface 1225A and the second conical surface 220 are frustum-shaped. The cooperation of the first conical surface 1225A and the second conical surface 220 is beneficial to ensure that the microphone 200 is placed at the middle position of the accommodation space 1211, so that the placement position of the microphone 200 will not shift.

[0042] Please refer to Figure 3 , Figure 4 , Figure 5 , in a possible implementation manner, the buffer seat member 122 further includes a second electromagnet 1226. An installation groove 1225B is provided at the center position of the first electromagnet 1225, and the second electromagnet 1226 is disposed in the installation groove 1225B and connected to the sliding seat 1222. Exemplarily, the second electromagnet 1226 is circular, the installation groove 1225B is circular, and the thickness of the second electromagnet 1226 is less than the depth of the installation groove 1225B. In this embodiment, the first electromagnet 1225 is provided with the first conical surface 1225A, and the second conical surface 220 is formed on the microphone 200. When the microphone 200 is placed in the accommodation space 1211, the microphone 200 is centered by the cooperation of the first conical surface 1225A and the second conical surface 220. In addition, the buffer seat member 122 is further provided with the second electromagnet 1226. When the microphone 200 is placed in the accommodation space 1211, the second electromagnet 1226 and the mating magnet 210 are turned on. The attraction between the second electromagnet 1226 and the mating magnet 210 further centers the microphone 200. In addition, the microphone 200 is fixed in the accommodation space 1211 by the cooperation of the second electromagnet 1226 and the mating magnet 210, and the microphone 200 is prevented from shaking in the accommodation space 1211 by cooperating with the blocking portion 1212, which is beneficial to protecting the microphone 200.

[0043] Please refer toFigure 4 , Figure 6 , in a possible implementation, the blocking part 1212 includes a first blocking block 1212A, a second blocking block 1212B, and a third blocking block 1212C. The accommodating space 1211 includes an entrance end 1211A and an abutting end 1211B. The abutting end 1211B is arranged on the sliding seat 1222. The entrance end 1211A, the first blocking block 1212A, the second blocking block 1212B, the third blocking block 1212C, and the abutting end 1211B are sequentially arranged at intervals in the accommodating space 1211. Exemplarily, in this embodiment, there are four first blocking blocks 1212A, four second blocking blocks 1212B, and four third blocking blocks 1212C. The four first blocking blocks 1212A are all located on the same horizontal plane, the four second blocking blocks 1212B are all located on the same horizontal plane, and the four third blocking blocks 1212C are all located on the same horizontal plane.

[0044] Please refer to Figure 4 , Figure 6 , in a possible implementation, set the distance between the entrance end 1211A and the first blocking block 1212A as L1, set the distance between the first blocking block 1212A and the second blocking block 1212B as L2, set the distance between the second blocking block 1212B and the third blocking block 1212C as L3, and set the distance between the third blocking block 1212C and the abutting end 1211B as L4, satisfying the following relational expression: L1 = 3 * L2 = 5 * L3 = 7 * L4. Exemplarily, since when the microphone 200 falls, its falling speed will increase as the falling depth increases, it can be understood that in the direction of the microphone 200's fall, the arrangement of the blocking blocks becomes denser. In this embodiment, the distance settings of L1, L2, L3, and L4 follow the law of free-fall motion, which is beneficial to achieving the best deceleration effect.

[0045] Please refer to Figure 4 , Figure 6 , Figure 7In one possible embodiment, first stopper 1212A includes a first arcuate surface 1213 and a second arcuate surface 1214. The first arcuate surface 1213 is connected to the second arcuate surface 1214. The second arcuate surface 1214 is located at the end facing away from the inner wall of storage tube 121. As the inner wall of accommodating space 1211 moves toward the axis of accommodating space 1211, first arcuate surface 1213 gradually approaches abutting end 1211B. For example, the provision of first arcuate surface 1213 facilitates downward deformation of first stopper 1212A, second stopper 1212B, or third stopper 1212C when microphone 200 contacts them, thereby blocking microphone 200 and reducing its falling speed. In addition, the first arc surface 1213 and the second arc surface 1214 are also provided to protect the microphone 200 from being scratched.

[0046] Please refer to Figure 4 , Figure 6 , Figure 7 In one possible embodiment, first stopper 1212A further includes a deformation groove 1212D, which is disposed on a side facing away from first arcuate surface 1213. Second stopper 1212B and third stopper 1212C have the same structure as first stopper 1212A. For example, the provision of deformation groove 1212D reduces the thickness of first stopper 1212A, second stopper 1212B, and third stopper 1212C, making them more easily deformable.

[0047] Please refer to Figure 4 , Figure 6 , Figure 7 In one possible embodiment, the first blocking block 1212A extends along the inner wall of the accommodating space 1211 to a length H1, the second blocking block 1212B extends along the inner wall of the accommodating space 1211 to a length H2, and the third blocking block 1212C extends along the inner wall of the accommodating space 1211 to a length H3. The values of H1, H2, and H3 gradually increase. For example, the closer to the abutment end 1211B, the greater the speed of the microphone 200. Based on this consideration, the first blocking block 1212A, the second blocking block 1212B, and the third blocking block 1212C are configured to have different extension lengths. As can be appreciated, the closer to the abutment end 1211B, the longer the blocking block, the greater the blocking effect on the microphone 200. In other words, the blocking effects of the first blocking block 1212A, the second blocking block 1212B, and the third blocking block 1212C on the microphone 200 increase in that order.

[0048] Please refer toFigure 4 , Figure 6 , Figure 7 , in a possible implementation, the accommodation space 1211 includes an entrance groove 1211C and a placement groove 1211D. The entrance groove 1211C and the placement groove 1211D are communicated. The entrance end 1211A is disposed at one end of the entrance groove 1211C away from the placement groove 1211D. And in the direction of the entrance end 1211A facing the placement groove 1211D, the aperture of the entrance groove 1211C gradually decreases. The blocking portion 1212 is disposed in the placement groove 1211D, and a sealing ring 1211E is disposed on the entrance groove 1211C. Exemplarily, the entrance groove 1211C is in the shape of an inverted frustum. The head of the microphone 200 is adapted to the shape of the entrance groove 1211C. On the one hand, it is beneficial to ensure that when the head of the microphone 200 contacts the inner wall surface of the entrance groove 1211C, the microphone 200 will not continue to fall downward. On the other hand, the head of the microphone 200 contacts the sealing ring 1211E, so that when the microphone 200 is placed in the accommodation space 1211, a seal can be formed between the microphone 200 and the sealing ring 1211E by the gravity of the microphone 200 itself. Thus, it is beneficial to ensure that when the microphone 200 is placed in the accommodation space 1211, the microphone 200 is sealed with the accommodation space 1211, thereby preventing dust from entering the accommodation space 1211.

[0049] A control method for an intelligent speaker 100, which is used to control the above-mentioned intelligent speaker 100. The method includes: when the microphone 200 is placed in, controlling the first electromagnet 1225 and the mating magnet 210 to turn on, and the second electromagnet 1226 to turn off, so that a first repulsive force is generated between the first electromagnet 1225 and the mating magnet 210, and the first repulsive force is less than the gravity of the microphone 200 itself. When the microphone 200 is placed in the accommodation space 1211, controlling the second electromagnet 1226 and the mating magnet 210 to turn on, and the first electromagnet 1225 to turn off, so that an attractive force is generated between the second electromagnet 1226 and the mating magnet 210. When the microphone 200 is taken out, controlling the first electromagnet 1225, the second electromagnet 1226 and the mating magnet 210 to turn on, so that both the first electromagnet 1225 and the second electromagnet 1226 generate repulsive forces with the mating magnet 210, and the acting forces of the two repulsive forces on the microphone 200 are the second repulsive force, and the second repulsive force is greater than the gravity of the microphone 200 itself. Exemplarily, when the microphone 200 is to be taken out, both the first electromagnet 1225 and the second electromagnet 1226 generate repulsive forces on the mating magnet 210, thereby ejecting the microphone 200 from the accommodation space 1211 for the user to easily pick up. When the microphone 200 is not placed in the accommodation space 1211, the first electromagnet 1225 and the mating magnet 210 are always in the on state, and the second electromagnet 1226 is in the off state, so as to be ready to respond at any time when the user puts the microphone 200 into the accommodation space 1211. When the microphone 200 is taken out, when the microphone 200 is placed in the accommodation space 1211 and the cover 113 is detected to be opened, or when the user triggers the ejection button, control the first electromagnet 1225, the second electromagnet 1226 and the mating magnet 210 to turn on to eject the microphone 200.

[0050] The above embodiments only represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention.
