[0033] Exemplary embodiments or implementations will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The implementations described in the following exemplary embodiments do not represent all implementations consistent with this application.

[0036] The smart sound is an electronic device that combines artificial intelligence technology and sound equipment. The smart sound can not only connect external smart devices through WiFi, Bluetooth or other wireless protocol standards, and realize functions such as playing music and outputting audio in home, shopping mall, conference, live broadcast and other scenes, but also can execute various tasks based on user voice instructions. For example, adjusting the volume of audio, switching song types, controlling smart home devices, etc.

[0037] In addition, some embodiments of the present specification provide a smart sound, which is also configured to wirelessly charge external smart devices. This function can make the smart sound have more use scenarios. For example, in the absence of external power supply (such as outdoor or power failure), the smart sound can supply power to external smart devices as a power supply, providing convenience for users.

[0038] At present, the smart sound has many parts and complex structure in the market, and the assembly is difficult. And the staff must assemble all the parts into a complete machine before they can fully test the electrical performance. However, once the performance problem is found in the test, the tedious disassembly work must be carried out to locate and repair the problem parts, which takes a long time and seriously affects the repair efficiency.

[0039] Therefore, some embodiments of the present specification provide a smart sound with simple structure, which can not only realize modular assembly to improve the assembly and disassembly speed, but also realize semi-finished product testing to improve the repair efficiency. In addition, the LOGO is magnetically attracted, which is convenient for users to replace.

[0040] It should be understood that the application scenario of the smart sound of the present application is only some examples or embodiments of the present application, and for those skilled in the art, the present application can be applied to other similar scenarios without creative labor according to the drawings.

[0041] Figure 1 is a schematic view of the internal structure of the smart sound shown in some embodiments of the present specification;Figure 2 is a schematic diagram of an internal explosion structure of a smart sound box according to some embodiments of the present specification.

[0042] Some embodiments of the present specification provide a smart sound box. As shown in Figure 1 , the smart sound box can include an inner cavity shell 1, a PCB board 2 and at least one loudspeaker 3, the inner cavity shell 1 has a cavity S, the PCB board 2 and the at least one loudspeaker 3 are arranged on the inner cavity shell 1 and are in communication with the cavity S.

[0043] The inner cavity shell 1 is the main part of the smart sound box, used to support other components on the smart sound box. The material of the inner cavity shell 1 can be wood material, plastic material, composite material, etc., which is not limited here.

[0044] The cavity S is an internal space surrounded by the inner cavity shell 1. The cavity S is used to adjust the sound of the smart sound box by affecting the propagation and reflection of sound.

[0045] In some embodiments, the size of the cavity S can be set according to actual needs. For example, a larger volume of the cavity S can be set to enhance the response of low frequency sound, and a smaller volume of the cavity S can be set to support the response of low frequency sound.

[0046] In some embodiments, the inner cavity shell 1 can be designed in a variety of structural shapes, including but not limited to at least one of rectangular prism, cone, cylinder, prism, sphere and irregular shape. The structural shape of the inner cavity shell 1 can be set according to actual needs. For example, the inner cavity shell 1 in the shape of a cone can be set to enhance the directivity of sound and reduce standing wave, and the inner cavity shell 1 in the shape of a cylinder can be set to provide uniform sound diffusion effect.

[0047] As shown in Figure 2 , the inner cavity shell 1 is provided with a mounting hole 11, and the mounting hole 11 is in communication with the cavity S. The mounting hole 11 can be used to mount other components of the smart sound box, such as the PCB board 2 and the loudspeaker 3. In some embodiments, the size, shape and number of the mounting hole 11 can be matched one by one with the size, shape and number of the PCB board 2 and the loudspeaker 3, respectively.

[0048] The PCB (Printed Circuit Board) board 2 is a substrate produced by circuit printing technology. In some embodiments, the at least one loudspeaker 3 is electrically connected to the PCB board 2.

[0049] Among them, the electrical connection refers to the establishment of electrical connection between components, so that electrical signals can be transmitted between connected components. Exemplary electrical connections can include but are not limited to plug-in, integral connection, welding, etc.

[0050] In some embodiments, at least one of the loudspeakers 3 is electrically connected to the PCB board 2, so that communication between the loudspeakers 3 and the PCB board 2 can be achieved, and thus the PCB board 2 can control the loudspeakers 3 to produce sound.

[0051] In some embodiments, the PCB board 2 is used to carry various electronic components, so as to realize the circuit function and the control function of the smart sound box. For example, the PCB board 2 can include a signal input interface, a signal processing unit, an amplification circuit, a control unit, and a signal output interface. When the sound source is input, the electrical signal is transmitted from the signal input interface, analyzed and processed by the signal processing unit, and then sent to the amplification circuit. Finally, the amplified electrical signal is transmitted to the loudspeaker coil through the output interface, driving the loudspeaker diaphragm to produce corresponding sound waves, and completing the sound output.

[0052] The loudspeaker 3 is a sound producing device of the smart sound box, which is used to convert electronic signals into sound.

[0053] For example, the loudspeaker 3 can include a magnet, a coil, a diaphragm, and a mounting frame. When the sound source is input, the electronic signal processed by the PCB board 2 forms a changing current, the coil generates a magnetic field by the current, the coil is vibrated by the magnetic force, and the vibrating diaphragm pushes the surrounding air to produce sound wave vibration, thereby producing sound output.

[0054] In some embodiments, the number of loudspeakers 3 can be set according to actual needs, which can be one or more. For example, in order to make the audience feel the sound from different directions and provide a more immersive audio experience, the number of loudspeakers 3 can be four, and the four loudspeakers 3 are arranged at different positions of the inner cavity shell 1.

[0055] In some embodiments, the PCB board 2 can be arranged on the mounting hole 11 and connected to the inner cavity shell 1, and at least one of the loudspeakers 3 can pass through the mounting hole 11 and be connected to the inner cavity shell 1. The example of the connection mode can include any one or a combination of welding, bonding, threaded connection, buckle connection, etc.

[0056] As shown in FIG. 1, Figure 1 In some embodiments, the PCB board 2 can be sealingly connected to the inner cavity shell 1.

[0057] In some embodiments, the PCB board 2 and the inner cavity shell 1 can be sealingly connected by a sealing agent. The sealing agent can be any one or a combination of butyl rubber sealing agent, epoxy resin sealing agent, acrylic sealing agent, etc.

[0058] In some embodiments, the PCB board 2 can also be sealingly connected to the inner cavity shell 1 by other any feasible means. For example, a sealing member can be arranged at the connection between the PCB board 2 and the inner cavity shell 1. The example of the sealing member can be a rubber gasket, a sealing strip, etc.

[0059] In some embodiments, the number of loudspeakers 3 is two, and the two loudspeakers 3 are symmetrically arranged on both sides of the inner cavity shell 1. One end of the two loudspeakers 3 is fixedly connected to the inner cavity shell 1, and the other end extends into the cavity S.

[0060] In some embodiments, one end of the two loudspeakers 3 can be fixedly connected to the two side surfaces of the inner cavity shell 1, and the other end can extend into the cavity S through the mounting hole 11 and be opposite to each other. In this way, sound waves can be transmitted in the same path and distance, and sound distortion can be reduced.

[0061] In some embodiments, a sealing member can be arranged between the loudspeaker 3 and the inner cavity shell 1 for sealing. On the one hand, the sealing member can effectively prevent air leakage and ensure that sound waves can be concentrated in the cavity S for transmission when the loudspeaker 3 is working, thereby improving the quality and output efficiency of the sound; on the other hand, the sealing member can absorb and block part of the vibration and resonance, thereby reducing the vibration generated by the loudspeaker 3 when working and affecting the sound quality.

[0062] In some embodiments of the present specification, the PCB board can act as an airtight member after being sealingly connected to the inner cavity shell, thereby not only saving materials and assembly processes without the need for additional independent airtight members, but also enabling the connection lines of other components to be connected to the main board PCB in the cavity. Further, by using two symmetrically arranged loudspeakers, a more uniform sound field can be created to improve the audio experience. Moreover, the loudspeaker is fixedly connected to the inner cavity shell, which not only reduces the loosening of the PCB board and the loudspeaker caused by vibration when the smart sound box is working, but also forms a closed cavity to avoid sound quality loss caused by air leakage and reduce sound distortion.

[0063] For more information about smart sound boxes, please refer to Figures 2-4 and related descriptions.

[0064] The PCB board and the loudspeaker are key components for realizing the function of a smart sound box. In some embodiments of the present specification, the PCB board and the loudspeaker are integrated into the inner cavity shell, which not only has a compact structure and optimizes the use of space, but also enables the key components of the smart sound box to form a separate module, which is helpful for the rapid assembly and replacement of the components of the smart sound box. Moreover, by forming a separate module for the key components of the smart sound box, the PCB board and the loudspeaker can be tested through an external power supply, thereby realizing the function verification and performance testing of the key components of the smart sound box before final assembly, saving testing procedures, improving repair efficiency, and also being conducive to improving production efficiency.

[0065] As shown in Figure 2 In some embodiments, the smart sound box can further include a battery 4, and the battery 4 is installed in the cavity S.

[0066] The battery 4 is used to supply power for the smart speaker.

[0067] In some embodiments, the battery 4 can be a rechargeable battery. In some embodiments, an external power source can charge the rechargeable battery, the rechargeable battery stores power and supplies power for the smart speaker, and in turn enables the smart speaker to work normally without the connection of the external power source. An exemplary rechargeable battery can be any one of a lithium-ion battery, a lithium polymer battery, a nickel-hydrogen battery, etc.

[0068] In some embodiments, the battery 4 can also be a non-rechargeable battery. An exemplary non-rechargeable battery can be any one of an alkaline battery, a silver-zinc battery, and an alkaline zinc-manganese battery, etc.

[0069] In some embodiments, a mounting seat 12 can be arranged in the cavity S of the inner cavity shell 1, and the battery 4 is mounted in the cavity S through the mounting seat 12.

[0070] In some embodiments, the mounting seat 12 can be connected to the inner cavity shell 1. An exemplary connection manner can include any one or a combination of welding, bonding, threaded connection, snap connection, etc.

[0071] In some embodiments, the structure, shape, size, etc. of the mounting seat 12 can be designed according to the structure, shape, size, etc. of the battery 4. For example, the battery 4 is in a cylindrical shape, and the mounting seat 12 can be designed to have a circular groove structure to adapt to the cylindrical battery 4, so as to ensure that the battery 4 can be stably fixed on the mounting seat 12.

[0072] Some embodiments of the present specification, by providing a battery for the smart speaker, can make it adapt to more diversified use environments. Integrating the battery into the cavity can also make the battery, the inner cavity shell, the PCB board, and the loudspeaker form a single module, so that the smart speaker can be tested as a whole when it is still in a semi-finished state, and problems can be found and parts can be replaced in time.

[0073] As shown in FIG. 1, Figure 2 In some embodiments, the smart speaker can further include a passive cone 5, which can be arranged at the bottom side of the inner cavity shell 1 and in communication with the cavity S.

[0074] The passive cone 5 refers to a component that depends on the compression of air in the acoustic cavity (i.e., the cavity S of the inner cavity shell 1) when the loudspeaker 3 works to emit sound, and passively vibrates to emit sound. In some embodiments, the passive cone 5 can be used to enhance the response of low-frequency sound.

[0075] In some embodiments, the passive cone 5 can be sealingly connected to the bottom side of the inner cavity shell 1 through a sealing member. The sealing member can be an elastic sealing member, which can provide sufficient elasticity for the passive cone 5 to support vibration.

[0076] In some embodiments, the passive basin 5 can also be connected to the inner cavity housing 1 by any other feasible means. Exemplary connection methods include, but are not limited to, threaded connection, adhesive bonding, etc.

[0077] In some embodiments, the passive diaphragm 5 may include a diaphragm and a suspension edge. The diaphragm is connected to the inner housing 1 via the suspension edge and is located in the cavity S. When the speaker 3 of the smart speaker vibrates and causes a pressure change in the internal air in the cavity S, the suspension edge allows the diaphragm to vibrate freely under the pressure difference, thereby amplifying the sound wave output.

[0078] In some embodiments, the material of the passive basin 5 is not limited and can be any one or a combination of polymers, rubber, composite materials, etc. For example, the passive basin 5 can be made of polypropylene, which is lightweight, provides flexible design, and is durable and resistant to environmental impacts.

[0079] The passive radiator 5 enhances low frequencies using acoustic principles through physical vibration response rather than driver signals. In some embodiments described in this specification, by incorporating a passive radiator into a smart speaker, low-frequency output can be amplified without consuming additional power, thus improving the speaker's bass performance. Furthermore, the placement and connectivity of the passive radiator reduce harmonic distortion and wind noise, providing a smoother and more natural sound quality.

[0080] like Figure 2 As shown, in some embodiments, the smart speaker may also include a light-emitting component 6.

[0081] The light-emitting component 6 refers to a part capable of emitting light, used to provide illumination for the smart speaker. In some embodiments, the structure of the light-emitting component 6 includes, but is not limited to, flexible light strips, lamp tubes, etc.

[0082] In some embodiments, the light-emitting component 6 is disposed around at least one horn 3 on the inner cavity housing 1. In some embodiments, the light-emitting component 6 is disposed correspondingly to the horn 3, and one horn 3 may be correspondingly provided with one light-emitting component 3. In some embodiments, the light-emitting component 6 can be disposed on the inner cavity housing 1 in various ways. Exemplary disposal methods include, but are not limited to, threaded connection, adhesive bonding, etc.

[0083] In some embodiments, the light-emitting component 6 is at least partially close to and electrically connected to the PCB board 2. Understandably, because the light-emitting component 6 is close to the PCB board 2, the required connection lines are shorter. Shorter lines can reduce resistance, thereby reducing power loss, and also help improve the speed and stability of signal transmission.

[0084] In some embodiments, the light-emitting component 6 includes at least one light source.

[0085] In some embodiments, the PCB board 2 can comprise a controller to control the light source. The controller can be used to control the light source of the light emitting assembly 6 which can be programmed to implement different lighting modes.

[0086] The lighting mode can comprise any one or a combination of decorative lighting, status indication, functional lighting, etc. For example, the controller can implement decorative lighting by adjusting the current intensity to change the brightness or color temperature of the light source. For another example, the controller can implement status indication by controlling the light source to work in different colors to change the color of the light. For example, green color indicates normal operation of the device.

[0087] Some embodiments of the present specification can enhance the visual appeal of the smart speaker by providing the light emitting assembly for the smart speaker, and present the running status or user interaction information of the speaker through visual feedback.

[0088] Figure 3 is a schematic diagram of the overall explosion structure of the smart speaker according to some embodiments of the present specification.

[0089] As shown in Figure 3 some embodiments, the light emitting assembly 6 can comprise at least one LED lamp 61 and a lamp plate 62, the lamp plate 62 being fixedly connected with the inner cavity shell 1, and the at least one LED lamp 61 being uniformly distributed on the lamp plate 62.

[0090] The LED (Light Emitting Diode) lamp 61 refers to a semiconductor device that converts electrical energy into light energy, which is used to provide light for the smart speaker. Exemplary LED lamp 61 can be any one or a combination of single-color LED lamp, multi-color LED lamp, etc.

[0091] In some embodiments, the number of LED lamps 61 can be one or more.

[0092] In some embodiments, when the number of LED lamps 61 is one, the LED lamp 61 can be a flexible LED lamp strip. The flexible LED lamp strip can be flexibly installed in irregular or limited space, providing continuous and uniform light effect.

[0093] In some embodiments, when the number of LED lamps 61 is more than one, the LED lamp 61 can be a patch LED lamp and be arranged on the lamp plate 62 at equal intervals. The patch LED lamp can achieve higher light efficiency and lower power consumption while ensuring uniformity of light source distribution.

[0094] The lamp plate 62 refers to a mounting plate for mounting the LED lamp 61. In some embodiments, the lamp plate 62 can be a circuit board. For example, the lamp plate 62 can be any one or a combination of flexible lamp plate, single-layer lamp plate, FR-4 lamp plate, etc.

[0095] In some embodiments, the lamp plate 62 can be designed in various structural shapes such as U-shaped, mouth-shaped, etc., and arranged around the peripheral side of the horn 3. The at least one LED lamp 61 is uniformly distributed on the lamp plate 62 and fixedly connected to the inner cavity shell 1 through the lamp plate 62.

[0096] In some embodiments, the lamp plate 62 can be fixedly connected to the inner cavity shell 1 in various ways. Exemplary fixed connection ways can be any one or a combination of bonding, welding, riveting, etc. As shown in Figure 2 the lamp plate 62 and the inner cavity shell 1 can be fixedly connected through the screw 63.

[0097] In some embodiments of the present specification, by arranging the LED and the lamp plate, a low-energy-consumption and high-quality light effect can be provided for the smart sound. Further, by connecting the LED lamp to the inner cavity shell through the lamp plate, the modularization of the light-emitting assembly is realized, allowing it to be tested and installed as an independent unit, simplifying the production and maintenance process.

[0098] As shown in Figures 2-3 in some embodiments, the smart sound further includes a charging assembly 7, and the upper surface of the inner cavity shell 1 is provided with a mounting groove 8, and the charging assembly 7 is arranged in the mounting groove 8. The charging assembly 7 is electrically connected with the PCB 2 and is configured to wirelessly charge an external smart device (not shown in the figure).

[0099] The charging assembly 7 refers to a device or apparatus for wirelessly charging an external smart device. In some embodiments, the charging assembly 7 can include but is not limited to a charging coil, etc.

[0100] The mounting groove 8 refers to a groove structure for accommodating or mounting the charging assembly 7. In some embodiments, the structural shape and size of the mounting groove 8 are not limited, as long as it can accommodate and fix the charging assembly 7.

[0101] As shown in Figures 2-3 the side close to the PCB 2 of the mounting groove 8 is provided with a reserved passage 81. The reserved passage 81 can be used for the connection line 71 connecting the battery 4 and the charging assembly 7 to pass through. Understandably, by arranging the reserved passage 81, the required connection line 71 can be shorter, achieving aesthetics while making the line shorter and avoiding the connection line 71 from being tangled.

[0102] In some embodiments, the charging assembly 7 can be arranged in the mounting groove 8 in various ways. For example, through snap connection, bonding, threaded connection, etc.

[0103] The external smart device refers to a smart terminal device capable of wireless charging. For example, a smart phone, a tablet computer, etc.

[0104] Wireless charging, also known as induction charging or contactless induction charging, is a charging method using near-field induction, i.e. inductive coupling, through electromagnetic induction principle. Specifically, wireless charging is achieved by arranging a coil at each of a sending end and a receiving end, the sending end coil (e.g. a charging coil) sends electromagnetic signals outward under the action of electric power, and the receiving end coil receives the electromagnetic signals and converts them into electric current, thereby achieving wireless charging.

[0105] In some embodiments, an external smart device can be placed on the top of the outer shell 9 in a region corresponding to the charging assembly 7 to achieve the wireless charging function.

[0106] In some embodiments, the power source for achieving the wireless charging function of the external smart device can be at least one of the battery 4 or an external power source. For example, when the smart sound is connected to an external power source, the external smart device can be powered by the battery 4 and / or the external power source. For another example, when the smart sound is not connected to an external power source, the external smart device can be powered by the battery 4.

[0107] In some embodiments of the present specification, the charging assembly is fixed on the upper surface of the inner cavity shell instead of being fixed on the inner side of the outer shell. This design can enable performance testing of the smart sound without installing the outer shell, and when the performance testing is passed, the outer shell is installed, i.e. the performance testing is not required after the smart sound is assembled as a whole, which can effectively reduce the repair time. In addition, since the outer shell and the charging assembly are independent of each other, there is no need to reserve additional wires for the installation and removal of the outer shell, which effectively avoids the problem of wire winding and optimizes the overall structure and operation efficiency.

[0108] Figure 4 is a schematic diagram of the overall structure of the smart sound according to some embodiments of the present specification.

[0109] As shown in Figures 3-4 some embodiments, the smart sound further includes an outer shell 9 and a bottom shell assembly 10, and the outer shell 9 covers the outer surface of the inner cavity shell 1. The bottom shell assembly 10 is arranged at the bottom of the inner cavity shell 1 and is fixedly connected with the outer shell 9 and the inner cavity shell 1.

[0110] The outer shell 9 is the main structure of the outer shell of the smart sound. In some embodiments, the outer shell 9 covers the outer surface of the inner cavity shell 1 and is used to accommodate or mount other components of the smart sound. The material of the outer shell 9 is not limited and can be wood material, plastic material, composite material, etc. In some embodiments, the outer shell 9 is at least partially transparent (e.g. acrylic plate, etc.) to facilitate the light emitted by the light emitting assembly 6 to pass through.

[0111] In some embodiments, the structure shape and size of the outer shell 9 can be designed according to the structure shape and size of the inner cavity shell 1. For example, the outer shell 9 can be designed as at least one of a cuboid, a cone, a cylinder, a prism, a sphere, and an irregular shape.

[0112] In some embodiments, the housing 9 may be provided with other components (such as button assembly 91) to facilitate user operation of the smart speaker. More details about the button assembly can be found in the following description.

[0113] The bottom shell assembly 10 is another structure that constitutes the outer shell of the smart speaker. In some embodiments, the bottom shell assembly 10 and the outer shell 9 together constitute the complete outer shell of the smart speaker. The bottom shell assembly 10 and the outer shell 9 may be made of the same or different materials, which is not limited here.

[0114] In some embodiments, the bottom shell assembly 10 is provided correspondingly to the outer shell 9, and its structural shape and size can be determined according to the structural shape and size of the outer shell 9.

[0115] like Figure 3 As shown, in some embodiments, the bottom shell assembly 10 is provided with a hole 101. The hole 101 can provide vibration space for the passive basin 5 so that the passive basin 5 can vibrate better.

[0116] In some embodiments, the bottom shell assembly 10 can be fixedly connected to the outer shell 9 and the inner cavity shell 1 in various ways. Exemplary fixed connection methods may include snap-fit ​​connection, adhesive bonding, welding, etc.
