DETAILED DESCRIPTION

[0049] The invention discloses a smart speaker, which is used to solve the technical problem that a sound column component of an existing smart speaker is prone to shaking and generating noise during reciprocating motion.

[0050] In order to enable those skilled in the art to better understand the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0051] See also Figures 1 to 12 , an embodiment of the present invention provides a smart speaker, comprising a speaker housing 1, a sound column assembly 2 and a driving assembly 7;

[0052] The driving assembly 7 is installed in the speaker housing 1, and the driving assembly 7 is connected to the sound column assembly 2 to drive the sound column assembly 2 to reciprocate relative to the speaker housing 1 along a first direction;

[0053] The driving component 7 is connected to a noise reduction component;

[0054] The smart speaker further includes a guide assembly, which is used to guide the sound column assembly 2 to reciprocate along the first direction.

[0055] It should be noted that, in this embodiment, the above-mentioned first direction specifically refers to the vertical direction, that is, the sound column assembly 2 can be driven to move back and forth in the vertical direction relative to the speaker shell 1. When the sound column assembly 2 is driven to move upward in the vertical direction, it can extend outside the speaker shell 1. When the sound column assembly 2 is driven to move downward in the vertical direction, it can be stored inside the speaker shell 1.

[0056] In the smart speaker of this embodiment, the guide assembly can guide the sound column assembly 2 to reciprocate along a first direction, effectively preventing the sound column assembly 2 from moving in directions other than the first direction. This prevents the sound column assembly 2 from shaking during reciprocating movement, greatly improving the movement stability of the sound column assembly 2. Furthermore, a noise reduction assembly is connected to the drive assembly 7 used to drive the sound column assembly 2, which can effectively reduce noise during operation of the drive assembly 7.

[0057] Furthermore, the sound column assembly 2 in this embodiment includes a sound column body 202 and a sound column housing 201;

[0058] The sound column body 202 is movably mounted in the sound column housing 201;

[0059] The driving assembly 7 is connected to the sound column housing 201 and the sound column body 202, and when the driving assembly 7 drives the sound column housing 201 to reciprocate along the first direction relative to the speaker housing 1, the sound column body 202 is driven to reciprocate along the first direction relative to the sound column housing 201 synchronously.

[0060] It should be noted that, through the above design, the sound column assembly 2 can achieve two-stage reciprocating movement, that is, the sound column shell 201 is driven to reciprocate relative to the speaker shell 1, while the sound column body 202 is driven to reciprocate relative to the sound column shell 201.

[0061] Furthermore, the driving assembly 7 in this embodiment includes a motor, an inner lead screw 701 , an outer lead screw 702 and a connecting portion 705 ;

[0062] The motor is installed inside the speaker housing 1 and connected to the inner screw 701. The motor is used to drive the inner screw to rotate in a first direction. The bottom of the sound column housing 201 is provided with a first threaded portion 703, which is threadedly connected to the inner screw 701. The connecting portion 705 is rotatably installed on the bottom of the sound column housing 201. The outer screw 702 is movably sleeved outside the inner screw 701 and connected to the inner screw 701 through the connecting portion 705.

[0063] When the inner screw 701 is driven to rotate, the connecting portion 705 drives the outer screw 702 to rotate synchronously, and at the same time, the outer screw 702 reciprocates relative to the inner screw 701;

[0064] A second threaded portion 704 is connected to the bottom of the sound column body 202 , and the second threaded portion 704 is threadedly connected to the outer screw 702 .

[0065] It should be noted that the specific working principle of the driving component 7 in this embodiment is:

[0066] Taking the first direction as the vertical direction as an example, when the motor drives the inner lead screw 701 to rotate in the clockwise direction, the sound column housing 201 moves upward along the inner lead screw 701. Since the outer lead screw 702 is connected to the connecting portion 705, the outer lead screw 702 moves upward synchronously with the sound column housing 201, and the outer lead screw 702 also rises relative to the inner lead screw 701. At the same time, when the inner lead screw 701 rotates, the outer lead screw 702 is driven to rotate synchronously through the connecting portion 705. At this time, the sound column body 202 moves upward along the outer lead screw 702.

[0067] Furthermore, in this embodiment, a connecting portion 705 is rotatably connected to the bottom of the sound column housing 201. One end of the connecting portion has a circular mounting opening, and the other has an elliptical mounting opening. The circular and elliptical mounting openings communicate, facilitating the insertion of the outer lead screw 702 within the inner lead screw 701. The outer lead screw 702 is specifically a cylindrical body with a threaded outer wall, secured to the circular mounting opening. The inner lead screw 701 is specifically an elliptical cylinder with a threaded outer wall, movably inserted into the elliptical mounting opening. With this design, when the inner lead screw 701 rotates, the connecting portion 705 drives the outer lead screw 702 to rotate synchronously, allowing the outer lead screw to reciprocate relative to the inner lead screw 701. In this embodiment, the first threaded portion 703 and the second threaded portion 704 have identical structures, both being metal parts with threaded holes.

[0068] Furthermore, the guide assembly in this embodiment includes a first guide rail 5 and a first slider 6;

[0069] The first guide rail 5 is installed inside the speaker housing 1 , and the first slider 6 is installed on the outer wall of the sound column housing 201 . The first guide rail 5 extends along the first direction, and the first slider 6 is slidably connected to the first guide rail 5 .

[0070] It should be noted that in the above design, when the sound column housing 201 is driven to reciprocate relative to the speaker housing 1, the first slider 6 reciprocates along the first guide rail 5. The sliding cooperation between the first slider 6 and the first guide rail 5 can restrict the sound column housing 201 to reciprocating movement in the first direction, effectively preventing the sound column housing 201 from shaking left and right, and effectively improving the stability and smoothness of the sound column housing 201 during movement.

[0071] Furthermore, the guide assembly in this embodiment further includes a second guide rail 8 and a second slider 9;

[0072] The second guide rail 8 is mounted on the inner wall of the sound column housing 201 , and the second slider 9 is mounted on the outer wall of the sound column body 202 . The second guide rail 8 extends along the first direction, and the second slider 9 is slidably connected to the second guide rail 8 .

[0073] It should be noted that in the above design, when the sound column body 202 is driven to reciprocate relative to the sound column housing 201, the second slider 9 reciprocates along the second guide rail 8. The sliding engagement between the second slider 9 and the second guide rail 8 restricts the sound column body 202 to reciprocating motion in the first direction, effectively preventing the sound column body 202 from swaying left and right, and effectively improving the stability and smoothness of the sound column body 202 during movement.

[0074] Furthermore, the guide assembly in this embodiment further includes a pair of guide plates 4;

[0075] A pair of guide plates 4 are installed inside the speaker housing 1 at a preset distance and form a guide channel that matches the shape of the sound column housing 201. The sound column housing 201 is located in the guide channel.

[0076] It should be noted that, through the above design, the guide channel can limit the direction of the reciprocating movement of the sound column housing 201, so that the sound column housing 201 can only reciprocate in the first direction, which can also prevent the sound column housing 201 from shaking during the movement.

[0077] In addition, since a pair of guide plates 4 are installed in the speaker housing 1 at a preset distance, in order to save installation space and improve the compactness of the structure, the first guide rail 5 in this embodiment can be set between the pair of guide plates 4.

[0078] Furthermore, the noise reduction assembly in this embodiment includes a ball bearing 10;

[0079] The outer ring of the ball bearing 10 is connected to the bottom of the sound column housing 201 , and the inner ring of the ball bearing 10 is connected to the connecting portion 705 .

[0080] It should be noted that, through the above design, when the inner screw 701 rotates, the outer screw 702 and the connecting portion 705 will rotate synchronously. Since the connecting portion 705 needs to be arranged at the bottom of the sound column housing 201, the present embodiment uses the design of the above-mentioned ball bearing 10 to prevent the connecting portion 705 from rubbing against the relevant parts at the bottom of the sound column housing 201 during rotation, thereby achieving a noise reduction effect.

[0081] Furthermore, the noise reduction assembly in this embodiment further includes a first sliding sleeve 12, and the inner screw 701 is sleeved with the first sliding sleeve 12;

[0082] The outer side wall of the first sliding sleeve 12 contacts the inner side wall of the outer lead screw 702 .

[0083] It should be noted that, since the outer screw 702 will reciprocate relative to the inner screw 701 during the movement of the inner screw 701, the above design can reduce the friction generated by the relative movement of the inner screw 701 and the outer screw 702, thereby achieving a noise reduction effect.

[0084] Furthermore, a hollow guide tube 2021 is installed inside the sound column body 202 in this embodiment;

[0085] A plurality of support members 2022 spaced apart along a first direction are installed inside the sound column body 202, and the support members 2022 abut against the outer wall of the guide tube 2021;

[0086] The guide cylinder 2021 is movably sleeved on the outer screw 702;

[0087] The noise reduction assembly further includes a second sliding sleeve 11, and the second sliding sleeve 11 is sleeved on the outer screw 702;

[0088] The outer wall of the second sliding sleeve 11 contacts the inner wall of the guide cylinder 2021 .

[0089] It should be noted that the outer lead screw 702 is threadedly connected to the second threaded portion 704 and is inserted into the interior of the sound column body 202 through the second threaded portion 704. In order to prevent the outer lead screw 702 from affecting the internal structure of the sound column body 202 during movement, a guide cylinder 2021 movably sheathed around the outer lead screw 702 is provided in the sound column body 202 in this embodiment. The guide cylinder 2021 also has a guiding function, which can effectively limit the outer lead screw 702 to reciprocating movement only along the first direction.

[0090] In addition, since the outer screw 702 and the guide cylinder 2021 produce relative reciprocating motion during movement, the design of the above-mentioned second sliding sleeve 11 can reduce the friction generated by the relative movement of the outer screw 702 and the guide cylinder 2021, thereby achieving a noise reduction effect.

[0091] It should be further explained that the above-mentioned support member 2022 is specifically a plastic support ring that matches the structure of the guide cylinder 2021. The support member 2022 can provide supporting force to the guide cylinder 2021 when the guide cylinder 2021 moves relative to the outer screw 702.

[0092] Furthermore, the first sliding sleeve 12 and the second sliding sleeve 11 in this embodiment are graphite copper sleeves.

[0093] It should be noted that the graphite copper sleeve is made of a hot-pressed combination of high-purity graphite and high-strength copper alloy powder. It has the characteristics of self-lubrication and can automatically release graphite particles for lubrication during movement, thereby effectively reducing friction between parts and thus reducing noise.

[0094] Furthermore, the sound column body 202 in this embodiment is provided with a full-range speaker and / or a mid-range speaker and / or a high-frequency speaker;

[0095] In this embodiment, a low-frequency speaker is installed in the speaker housing 1 .

[0096] It should be noted that the speakers in the sound column body 202 of this embodiment are arranged at an angle to further expand the sound field. The specific examples are as follows:

[0097] Up and down opening: at least one speaker faces upwards, and at least one speaker faces downwards for directional output, and the above speakers can be full-range speakers;

[0098] Left and right opening: at least one speaker faces left, at least one speaker faces right, and they can also be arranged oppositely. The above speakers can be full-range speakers;

[0099] Comprehensive opening: at least one speaker faces forward, at least one speaker faces the upper left and lower right, and at least one speaker faces the lower right and upper left;

[0100] The sound column body 202 in this embodiment cooperates with the low-frequency speaker to output in advance, so that the front sound field is evenly filled.

[0101] Furthermore, the smart speaker in this embodiment also includes a display screen 3;

[0102] The top of the speaker housing 1 is provided with a storage groove for storing the display screen 3 , and the storage groove is recessed into the interior of the speaker housing 1 .

[0103] It should be noted that the smart speaker in this embodiment can be connected to the speaker housing 1 in a hinged manner. When the user does not need to use the display screen 3, it can be rotated to the position of the storage slot to store the display screen 3.

[0104] Furthermore, the speaker housing 1 in this embodiment is also provided with a microphone storage structure for storing a microphone. The microphone storage structure can be a storage groove provided on the speaker housing 1, which is recessed toward the interior of the speaker housing 1, and the microphone is stored in the storage groove. In addition, in order to facilitate the user to take the microphone, a lifting drive member can be provided in the storage groove to drive the microphone to extend out of the storage groove or be stored in the storage groove, or an elastic pressing component can be installed in the storage groove. The user can lock the microphone in the storage groove by pressing the microphone, and the user can press the microphone again to put the microphone in an unlocked floating state for the user to take it away. The above-mentioned elastic pressing component is a prior art and is not introduced in detail in this embodiment.

[0105] Furthermore, the smart speaker in this embodiment also includes a control circuit board, which is installed inside the speaker housing 1, and the speaker assembly, display screen 3 and lifting drive component in the speaker are electrically connected to the control circuit board. The control circuit board is also electrically connected to a communication module, and the microphone is wirelessly connected to the control circuit board through the communication module.

[0106] It should be noted that the microphone is connected to the control circuit board through the communication module, so that the user's voice signal can be processed by the control circuit board and then broadcasted by the speaker.

[0107] In addition, in the speaker of this embodiment, when there are two or more microphones, the user can control the two or more microphones to rise and fall synchronously or individually according to the user's choice. The above process can be achieved mainly by entering a program into the control circuit board. It is achievable for those skilled in the art and is not described in detail in this embodiment.

[0108] Furthermore, the display screen 3 in this embodiment can be opened electrically or manually, and this embodiment does not impose any restrictions on this. Designers can design according to actual needs. In addition, in this embodiment, the display screen 3 in this embodiment can be linked with the lifting drive component through the control circuit board, that is, when the display screen 3 is opened, the lifting drive component synchronously drives the microphone to rise. The above method can also be implemented by general technicians in this field, and the embodiment does not provide a detailed introduction to this implementation method.

[0109] Furthermore, the depth of the accommodating groove is greater than or equal to the length of the microphone, and the microphone is inserted into the accommodating groove vertically or horizontally along the length direction through the opening of the accommodating groove to achieve storage. A microphone fixing structure can be set inside or outside the opening to fix the microphone after it is stored. The opening of the accommodating groove can be set at any position of the speaker shell 1, including the outer side of the speaker shell 1, such as the upper, lower, left and right outer sides.

[0110] In some specific embodiments, the opening of the accommodating groove can be set on the top surface of the storage groove. With this design, after the display screen 3 is closed, the microphone is completely covered by the display screen 3 and is completely stored in the speaker housing 1.

[0111] Furthermore, when the microphone is connected to the speaker, for example, if the distance between the microphone and the speaker is too close, the speaker will howl. The harsh howling sound emitted by the speaker will greatly affect the user experience. Especially when the speaker stores the microphone, the impact and friction sounds with the speaker shell 1 during the storage process of the microphone are more likely to cause howling. The microphone can be automatically shut down when it is stored in the storage slot to prevent howling when the microphone is close to the speaker or when the speaker stores the microphone.

[0112] In some specific embodiments, the microphone is automatically turned off by a sensing element sensing the distance between the speaker and the microphone. After sensing that the distance between the speaker and the microphone is less than or equal to a preset distance, the microphone automatically turns off. The sensing element can be one or more, and the sensing element can be a Hall element, a distance sensor, an infrared sensor, or any other single electronic component that can sense the distance between the speaker and the microphone, as well as any combination of electronic components. The sensing element can be arranged on the speaker and / or the microphone. Specifically, when the microphone is inserted into the accommodating slot, the sensing element can be arranged at the opening of the accommodating slot so that the microphone is turned off immediately when the microphone is just inserted into the opening. The sensing element can also be arranged at the end of the accommodating slot away from the opening to prevent the sensing element from being exposed to the outside due to the opening facing outward, which may cause aging of the element.

[0113] In one specific embodiment, the sensing element is a Hall element, the microphone storage structure and the microphone each have a corresponding position, a magnetic part is set at the corresponding position of the microphone and a Hall element is set at the corresponding position of the speaker shell 1, or a Hall element is set at the corresponding position of the microphone and a magnetic part is set at the corresponding position of the speaker shell 1. The triggering condition of the Hall element can be that the detected magnetic field strength reaches a preset value. When the detected magnetic field strength is greater than or equal to the preset value, it means that the distance between the speaker and the microphone meets the requirements for causing howling, and the microphone needs to be turned off. Preferably, a magnetic part is set at the corresponding position of the microphone and a Hall element is set at the corresponding position of the speaker shell 1. Since the microphone moves around during karaoke, it may move to other places with a larger magnetic field strength. Setting a Hall element on the microphone may cause the microphone to shut down incorrectly, thereby affecting the experience. When the microphone is inserted into the accommodating slot, the Hall element is set at the opening of the accommodating slot of the speaker shell 1 or at the end away from the opening.

[0114] In another specific embodiment, the sensing element is a Hall element, a charging structure is correspondingly provided on the speaker housing 1, and a power receiving structure is correspondingly provided on the microphone. The triggering condition of the Hall element can be a change in the magnetic field caused by the moment the microphone is powered on when charging. When a change in the magnetic field is detected, it means that the distance between the speaker and the microphone is sufficient to cause howling, and the microphone needs to be turned off. The charging structure can be provided on the outer side of the speaker housing 1, or it can be provided in a corresponding accommodating groove. The microphone can be inserted and stored. The charging structure is provided at the end of the accommodating groove of the speaker housing 1 away from the opening. The power receiving structure is provided on the bottom or bottom surface of the end of the microphone. The Hall element is provided near the charging structure. The Hall element can sense the change in the magnetic field caused by the moment of power on.

[0115] In this embodiment of the microphone storage structure, when the user needs to use the microphone, the lifting drive member can be controlled to automatically extend the microphone from the opening of the storage slot. At this time, the user can directly remove the microphone and use it. When the user no longer needs to use the microphone, the user can directly insert the microphone into the storage slot. Then, the lifting drive member drives the microphone to automatically descend and store it in the storage slot. This design makes it simple and direct to remove and place the microphone, greatly reducing the difficulty of removal and effectively improving the efficiency of removal and placement.

[0116] The above is a detailed introduction to the smart speaker provided by the present invention. For those skilled in the art, according to the ideas of the embodiments of the present invention, there may be changes in the specific implementation methods and application scopes. In summary, the content of this specification should not be understood as limiting the present invention.
