[0019] This manual provides a sound pressure-driven, light-effect visualization speaker. It converts the physical sound pressure signals inside the speaker or in the near-field area into dynamic light effects using precise sound pressure sensors and controllers. This visualizes abstract sound wave energy as dynamic and rich physical light and shadow, thereby enhancing the user's immersion. Light effect visualization refers to the use of visual effects produced by light (i.e., light effects) to interact with audio performance, thereby enhancing the user experience.

[0020] Figure 1 This is an exemplary structural diagram of a sound pressure-driven light effect visualization speaker according to some embodiments of this specification. Figure 2 This is an exemplary overall schematic diagram of a sound pressure-driven light effect visualization speaker according to some embodiments of this specification.

[0021] In some embodiments, such as Figure 1 and Figure 2 As shown, a sound pressure-driven light effect visualization speaker 100 (hereinafter referred to as "speaker 100") may include a cabinet 10, a speaker 20, a transparent module 30, an optical component 40, a sound pressure sensor 50, and a controller 60.

[0022] The enclosure 10 serves as a carrier for housing other components of the speaker 100. In some embodiments, the enclosure 10 may include a front panel 11 and a rear panel 12. In some embodiments, the enclosure 10 may be made of a material with good acoustic properties, such as solid wood or high-density composite materials.

[0023] The speaker 20 is a component used to generate sound waves. In some embodiments, the speaker 20 is fixedly disposed inside the front panel 11 of the enclosure 10. For example, the speaker 20 is fixedly disposed inside the front panel 11 of the enclosure 10. In some embodiments, the speaker 20 is configured to generate a sound pressure signal. A sound pressure signal is a signal that reflects the change in medium pressure caused by sound waves. For example, the speaker 20 can convert an audio-level electrical signal into a corresponding vibration that drives the surrounding air to generate sound waves, thereby generating a sound pressure signal inside the enclosure 10 or in the near-field region.

[0024] The transparent module 30 is a carrier used to connect the optical component 40 and the outside of the housing 10 via an optical path to achieve visualization of light effects. For example, the transparent module 30 can be a completely transparent cuboid, cylinder, or a housing with transparent sidewalls. In some embodiments, the transparent module 30 is embedded in the top or bottom side of the housing 10. For example, the transparent module 30 is embedded in the bottom side of the housing 10, such as... Figure 1 As shown. In some embodiments, the transparent module 30 includes a light-emitting surface 31, which is the surface of the transparent module 30 facing the outside of the housing 10, for transmitting light generated by the optical component 40 so that the user can observe the light effect from the outside of the housing 10. In some embodiments, the light-emitting surface 31 is located on the top or bottom surface of the housing 10. For example, when the transparent module 30 is embedded on the top side of the housing 10, the light-emitting surface 31 is located on the top surface of the housing 10; when the transparent module 30 is embedded on the bottom side of the housing 10, the light-emitting surface 31 is located on the bottom surface of the housing 10. Exemplarily, the light-emitting surface 31 may be disposed in the middle region of the top or bottom surface of the housing 10, see [reference]. Figure 4 .

[0025] The optical component 40 is a component used to generate light effects. In some embodiments, the optical component 40 is disposed inside the transparent module 30.

[0026] In some embodiments, the optical component 40 includes a plurality of light-emitting elements 41. Each light-emitting element 41 is a component capable of generating light. For example, the light-emitting element 41 can be a light-emitting diode (LED), a laser diode (LD), or an organic light-emitting diode (OLED). Alternatively, the light-emitting element 41 can be an addressable RGB LED. In some embodiments, the plurality of light-emitting elements 41 are fixedly disposed on the side of the transparent module 30 facing the interior of the housing 10, and at least a portion of the light generated by the plurality of light-emitting elements 41 can penetrate through the light-emitting surface 31.

[0027] The sound pressure sensor 50 is a sensor used to collect sound pressure signals. In some embodiments, the sound pressure sensor 50 is spaced apart from the speaker 20. For example, the sound pressure sensor 50 may be installed at a predetermined distance from the speaker 20, and the mounting surface may face the speaker 20. By spaced the sound pressure sensor 50, the sound pressure sensor 50 can capture the air vibrations caused by the sound waves emitted by the speaker 20, thereby collecting the sound pressure signal generated by the speaker 20.

[0028] In some embodiments, the sound pressure sensor 50 is configured to acquire sound pressure signals and convert them into electrical signals in real time. For example, the sound pressure sensor 50 can be a micro-electro-mechanical system (MEMS) microphone, capable of converting sound pressure changes into capacitance changes or voltage changes, thereby converting the sound pressure signal into an electrical signal.

[0029] The controller 60 is a device used to process electrical signals and control devices such as the optical component 40 to produce different light effects. In some embodiments, the controller 60 is disposed inside the housing 10 and is electrically connected to the sound pressure sensor 50 and the optical component 40. For example, the controller 60 can be electrically connected to the sound pressure sensor 50 and multiple light-emitting elements 41 of the optical component 40 via wires.

[0030] In some embodiments, controller 60 may include one or more sub-processing devices. By way of example only, controller 60 may include a central processing unit (CPU), a digital signal processor (DSP), a microcontroller unit (MCU), or any combination thereof.

[0031] In some embodiments, the controller 60 is configured to control the light-emitting state of multiple light-emitting elements 41 according to an electrical signal. For example, the controller 60 can perform real-time analysis and processing of the electrical signal (e.g., using Fourier transform, wavelet transform, etc.) to obtain audio features, such as sound pressure level and spectral characteristics, and control whether the multiple light-emitting elements 41 emit light, as well as the color and brightness of the emitted light, according to the audio features. For example, a higher sound pressure level corresponds to a higher brightness of the light-emitting element 41, and different frequencies correspond to different colors of the light-emitting element 41.

[0032] In some embodiments, the speaker 100 further includes a button group 13. The button group 13 is used to realize user interaction. In some embodiments, the button group 13 can be electrically connected to the controller 60, and the user can control the working state of the speaker 100 through different buttons of the button group 13. For example, the user can control the power on / off state, volume increase / decrease, play / pause, track skipping, and light effect mode switching of the speaker 100 through the button group 13. The light effect mode can refer to a preset light effect mode, such as a light effect mode with different color combinations. In some embodiments, the button group 13 can be located on the side of the speaker 100 opposite to the light-emitting surface 31 of the transparent module 30. In other embodiments, the button group 13 can also be located on the front panel 11 of the speaker 100.

[0033] In some embodiments, the speaker 100 may also include feet 14. The feet 14 are used for vibration damping and anti-slip purposes of the speaker 100. The feet 14 may be made of sponge, rubber, or silicone, and may have anti-slip textures on the bottom. The feet 14 help reduce vibrations from the speaker 100 to the surface on which it is placed, and also reduce wear on the bottom surface of the speaker 100.

[0034] In some embodiments, the speaker 100 may further include a preamplifier. In some embodiments, the preamplifier may be used to amplify the audio signal or the sound pressure signal collected by the sound pressure sensor 50.

[0035] In some embodiments of this specification, by setting up a sound pressure-driven light effect visualization speaker including a cabinet, a speaker, a transparent module, optical components, a sound pressure sensor, and a controller, it is possible to achieve a responsive sound and light effect, providing users with a more immersive audiovisual experience.

[0036] Figure 3 This is an exemplary rear view of a sound pressure-driven light effect visualization speaker according to some embodiments of this specification.

[0037] In some embodiments, the speaker 100 also includes a transparent element 70.

[0038] The transparent element 70 is a component used to present light effects from a side different from the light-emitting surface of the transparent module 30. In some embodiments, the transparent element 70 may be disposed on the rear panel 12 of the housing 10, and at least a portion of the light generated by the optical assembly 40 may pass through the transparent element 70. For example, as Figure 1 and Figure 3 As shown, the transparent component 70 can be elongated. Alternatively, the transparent component 70 can be rectangular, elliptical, or similar shapes.

[0039] In some embodiments, the transparent module 30 and the transparent component 70 are made of polymethyl methacrylate (PMMA) or polycarbonate (PC). For example, high-transmittance PMMA or PC can be selected, and the transparent module 30 and the transparent component 70 are manufactured by precision injection molding. High transmittance can refer to a transmittance exceeding 90%, such as PMMA with 92% transmittance or PC with 90.3% transmittance. By setting the material of the transparent module and the transparent component to PMMA or PC, the light effect of the light-emitting component can be better presented to the user through the transparent module and the transparent component, improving the visual perception of the light effect.

[0040] In some embodiments of this specification, by providing a transparent element on the rear panel of the housing, the light effect can be extended in a dimension different from the light-emitting surface of the transparent module, increasing the overall visual fluidity and improving the user experience.

[0041] It should be noted that the above description of the speaker 100 and its components is for convenience only and should not be construed as limiting this specification to the scope of the illustrated embodiments. It is understood that those skilled in the art, after understanding the principle of the device, may arbitrarily combine the various components or connect them to other components without departing from this principle. In some embodiments, Figure 1 The enclosure 10, speaker 20, transparent module 30, optical component 40, sound pressure sensor 50, controller 60 and transparent component 70 disclosed herein may be different components in one device, or one component may perform the functions of two or more of the above components.

[0042] In some embodiments, the optical component 40 further includes a plurality of light guides 42.

[0043] The light guide 42 is an accessory with a light guiding function. For example, the light guide 42 can be a light guide post, a light guide plate, etc. In some embodiments, multiple light guides 42 are located between multiple light-emitting elements 41 and the light-emitting surface 31, and at least a portion of the light emitted by the multiple light-emitting elements 41 is transmitted to the light-emitting surface 31 through the multiple light guides 42. In some embodiments, the multiple light guides 42 may correspond one-to-one with the multiple light-emitting elements 41. In other embodiments, one light guide 42 may correspond to multiple light-emitting elements 41, or multiple light guides 42 may correspond to one light-emitting element 41.

[0044] In some embodiments, the light guide 42 may be made of a material with high light transmittance. For example, it may be PMMA, PC, etc.

[0045] In some embodiments, the light guide 42 is located between the plurality of light-emitting elements 41 and the light-emitting surface 31. When the plurality of light-emitting elements 41 emit light, the light guide 42 can act as an intermediate medium to transmit at least part of the light emitted by the plurality of light-emitting elements 41 to the light-emitting surface 31.

[0046] In some embodiments of this specification, by providing a light guide 42 between multiple light-emitting elements 41 and the light-emitting surface 31, a point light source can be converted into a surface light source with uniform brightness and no glare. It can also maximize the collection of light emitted by the light-emitting elements 41 and efficiently transmit it to the light-emitting surface 31, reducing the loss of light energy during transmission.

[0047] In some embodiments, the light guide 42 can be a light guide post, the length direction of which is perpendicular to the light emitting surface 31.

[0048] A light guide is a cylindrical accessory with a light-guiding function. In some embodiments, the light guide can be transparent or semi-transparent. In some embodiments, one end of the light guide corresponds to the light-emitting element 41, and the other end corresponds to the light-emitting surface 31. For example, one end of the light guide can be aligned with the light-emitting element 41 to achieve optical coupling with the light-emitting element 41, and the other end can be aligned with the light-emitting surface 31 to ensure better light guiding effect.

[0049] For details regarding the material of the light guide column, please refer to the previous description of the material of light guide component 42.

[0050] In some embodiments, the speaker 100 further includes a plurality of micro drivers 80, which are connected to a plurality of light guide columns.

[0051] The micro-driver 80 is a device that converts electrical energy into minute mechanical motion or force. In some embodiments, the micro-driver 80 can be as small as millimeters or even micrometers to meet the need for integration into space-sensitive products such as speakers.

[0052] In some embodiments, a micro-driver 80 can be connected to one or more light guide pillars to simultaneously drive one or more light guide pillars to move along their respective lengths. For example, a micro-driver 80 can be connected to the outer peripheral surface or end face of the tail end of a light guide pillar to drive the movement of that single light guide pillar. As another example, the micro-driver 80 can be provided with a connecting rod (not shown in the figure), and the side of the light guide pillar can be provided with a flange (not shown in the figure). A micro-driver 80 can connect the flanges on the side of multiple light guide pillars via the connecting rod to simultaneously drive the movement of multiple light guide pillars. In some embodiments, the micro-driver 80 may not be in direct contact with the light guide pillars. For example, a magnetic component can be provided at one end of multiple light guide pillars, and a coil can be provided inside the micro-driver 80. An electromagnetic driving force is generated by energizing the coil to drive the movement of one or more light guide pillars.

[0053] In some embodiments, a plurality of micro-drivers 80 are electrically connected to a controller 60. For example, the plurality of micro-drivers 80 are connected to the controller 60 via wires. In some embodiments, the plurality of micro-drivers 80 drive a plurality of light guide columns to move along their own length direction, respectively. For example, the plurality of micro-drivers 80 can drive the plurality of light guide columns to move along their own length direction at different frequencies and amplitudes according to electrical signals emitted by the controller 60.

[0054] In some embodiments of this specification, by driving multiple light guide columns to move along their own length direction using a micro-driver 80, the propagation path and light emission effect of light in the light guide columns can be changed, thereby altering the light effect presented on the light emission surface 31 and enhancing the information expression capability and visual appeal of the speaker 100. Furthermore, integrating the micro-driver 80 directly onto the light guide columns creates a compact structure that is ideal for high-density array arrangement within the limited internal space of the speaker, laying the foundation for achieving complex dynamic effects.

[0055] In some embodiments, the plurality of micro-drivers 80 and the plurality of light guides are arranged in an array.

[0056] Array-style setup refers to the regular and orderly arrangement of multiple components in a matrix form consisting of rows and columns.

[0057] In some embodiments, a plurality of micro-drivers 80 may form a driver array.

[0058] In some embodiments, multiple light guide pillars can form a light guide pillar array.

[0059] In some embodiments, the driving array and the light guide column array correspond spatially to each other, forming a cooperative integrated array. For example, one driving array can correspond to multiple light guide column arrays, forming an integrated array. As another example, the micro-drivers 80 in the driving array can correspond one-to-one with the light guide columns in the light guide column array, forming an integrated array.

[0060] In some embodiments of this specification, by arranging multiple micro-drivers 80 and multiple light guide columns in an array, the internal structure of the speaker 100 can be optimized and the space utilization rate can be improved. The array arrangement makes it easy to achieve regular light effect dynamics, which helps to provide a more immersive, uniform and comfortable light effect experience.

[0061] In some embodiments, the micro-driver 80 may be a piezoelectric ceramic driver or an electromagnetic driver.

[0062] Piezoelectric ceramic actuators can achieve mechanical actuation by utilizing the inverse piezoelectric effect, where piezoelectric ceramic materials deform when an electric field is applied. For example, the controller 60 can apply driving voltages of different magnitudes or frequencies. When the driving voltage is applied to the piezoelectric ceramic actuator, the actuator can produce micron or nanometer-level stretching or contraction displacement, thereby driving the light guide column to move linearly.

[0063] Electromagnetic actuators can achieve mechanical actuation based on the law of electromagnetic induction (Lorentz force). When using an electromagnetic actuator, corresponding magnetic components can be placed on the light guide column to generate a force. For example, when a changing current flows through the coil inside the electromagnetic actuator, the coil generates a force under the magnetic field provided by the magnetic components, thereby driving the light guide column to move linearly. In some embodiments, the controller 60 can generate a controllable magnetic force or torque by controlling the intensity and frequency of the coil current, driving the magnetic components disposed on the light guide column to move.

[0064] In some embodiments, the plurality of micro-drivers 80 may all be piezoelectric ceramic drivers, or all be electromagnetic drivers, or a combination of piezoelectric ceramic drivers and electromagnetic drivers.

[0065] In some embodiments of this specification, the micro-actuator 80 is configured as a piezoelectric ceramic actuator, which enables rapid and precise micro-displacement control, meeting the requirements of fast response and accurate positioning, and achieving nanometer-level resolution. Simultaneously, the piezoelectric ceramic actuator has a simple structure, is easy to miniaturize, and consumes almost no power when statically holding its position, perfectly meeting the energy-saving requirements of portable devices.

[0066] In some embodiments of this specification, the micro actuator 80 is configured as an electromagnetic actuator. Since the force output by the electromagnetic actuator has a good linear relationship with the input current, the control algorithm is simple and direct, and it is easy to achieve precise force and position control.

[0067] In some embodiments, the speaker 100 further includes a power module (not shown in the figure), and multiple light-emitting elements 41, sound pressure sensors 50, controllers 60, multiple micro drivers 80 and the power module are integrated on a circuit board 90, which is fixedly disposed on the side of the transparent module 30 facing the interior of the enclosure 10.

[0068] The power module is an integrated module that provides specific voltages and currents to various components inside the speaker 100 that require electrical energy.

[0069] In some embodiments, the power module can be connected to the battery in the speaker 100 to achieve power regulation and power supply.

[0070] Circuit board 90 is a substrate or carrier that provides mechanical support and electrical connection for electronic components and enables them to form specific functional circuits, thus realizing the integration, modularization, and miniaturization of electronic components. For example, circuit board 90 can be a printed circuit board (PCB).

[0071] In some embodiments, multiple light-emitting elements 41, sound pressure sensors 50, controllers 60, multiple micro-drivers 80, and power modules can be directly soldered to different functional areas on the circuit board 90, thereby integrating them on the circuit board 90.

[0072] In some embodiments, the circuit board 90 may be located between the transparent module 30 and the interior of the housing 10, and fixedly disposed on the side of the transparent module 30 facing the interior of the housing 10.

[0073] In some embodiments of this specification, all core electronic functions are integrated onto a single circuit board 90, forming an independent, standardized functional module. This simplifies the overall assembly process of the speaker 100 and improves production efficiency and product consistency. Simultaneously, it reduces internal cable connections, lowering the failure rate caused by loose connectors or cable wear, and enhancing the overall reliability and stability of the speaker 100.

[0074] In some embodiments, the speaker 100 further includes a passive radiator 111 and a mounting bracket 112.

[0075] The passive radiator 111 (also known as a passive cone) is a loudspeaker diaphragm without a driver unit (no voice coil and magnetic circuit). It is passively vibrated by changes in air pressure inside the cabinet 10 to enhance the low-frequency response of the speaker 100.

[0076] The mounting bracket 112 is a frame used to fix the passive radiator 111. In some embodiments, the passive radiator 111 is disposed between the circuit board 90 and the transparent module 30 by the mounting bracket 112. For example, the outer edge of the mounting bracket 112 can be fixedly connected to the inner wall of the housing 10, and at least a portion of the inner edge is connected to the passive radiator 111. A certain gap can be left between the mounting bracket 112 and the passive radiator 111 so that the passive radiator 111 can induce vibration based on sound waves.

[0077] In some embodiments, the mounting bracket 112 is provided with an opening area (not shown in the figure), through which multiple micro-drivers 80 can be connected to multiple light guide pillars. For example, multiple micro-drivers 80 themselves or their connected wires can pass through the opening area on the mounting bracket 112 and be mechanically connected to multiple light guide pillars. Since the displacement of the micro-drivers 80 is precisely controlled, the movement of the micro-drivers 80 can bypass the passive radiator 111.

[0078] In some embodiments, the diaphragm of the passive radiator 111 can be a transparent diaphragm with a reserved optical channel. The light generated by the multiple light-emitting elements 41 integrated on the circuit board 90 can pass through the reserved optical channel on the transparent diaphragm of the passive radiator 111 and enter one end of the multiple light guide pillars, thereby allowing the light to be transmitted from the other end of the light guide pillars to the light-emitting surface 31.

[0079] In some embodiments of this specification, by setting a passive radiator 111 and a mounting bracket 112, and providing an opening area on the passive radiator 111 and / or the mounting bracket 112, the speaker 100 can achieve both high-quality sound and light effects, providing users with a better audio-visual experience.

[0080] Figure 4 This is an exemplary schematic diagram of a sound pressure-driven light effect visualization speaker including a reflective component, according to some embodiments of this specification.

[0081] In some embodiments, such as Figure 4 As shown, the speaker 100 also includes a reflector assembly 120.

[0082] The reflective assembly 120 is a component used to adjust the propagation path of light emitted from the light-emitting surface 31. In some embodiments, the reflective assembly 120 includes a support 121 and a reflector 122 fixed to the support 121.

[0083] The bracket 121 is a structure used to fix and connect the reflector 122. In some embodiments, the bracket 121 is connected to the side of the housing 10 where the transparent module 30 is located. For example, the bracket 121 can be fixed to the plane where the light-emitting surface 31 of the transparent module 30 is located, and is disposed in close contact with one edge of the light-emitting surface 31.

[0084] The reflector 122 is a component used to reflect light emitted from the light-emitting surface 31. For example, the reflector 122 may include at least one of a reflector or a semi-transparent mirror. In some embodiments, the reflector 122 may be movably connected to the bracket 121 (e.g., hinged, rotatable, etc.) or detachably connected (e.g., snap-fit, bolted, etc.).

[0085] In some embodiments, the reflector 122 includes a reflective surface, which forms an adjustable angle with the light-emitting surface 31 (e.g., ...). Figure 4(As shown in a). For example, one side of the reflector 122 can be hinged to the bracket 121, allowing the user to manually adjust the reflector 122 to adjust the angle between the reflecting surface and the light-emitting surface 31. Alternatively, the bracket 121 can have multiple grooves along its length, each corresponding to a preset angle between the reflecting surface and the light-emitting surface 31. One side of the reflector 122 can have a protrusion that at least partially matches the shape of the groove. The reflector 122 is inserted into the bracket 121 via the protrusion and engages with the groove, then secured by bolts, clips, or other fasteners. When the angle needs adjustment, the reflector 122 can be removed and inserted into another groove. With these features, when the reflector 122 is not needed to reflect light, the angle between the reflecting surface and the light-emitting surface 31 can be adjusted to 90° or higher, or the reflector 122 can be detached (in the case of a detachable connection).

[0086] In some embodiments of this specification, by setting a reflective assembly 120 including a bracket 121 and a reflector 122, and making the reflector 122 form an adjustable angle with the light-emitting surface 31, the propagation path of the light effect can be made more flexible. Users can adjust the reflector 122 according to their needs to achieve richer light effects and enhance the audiovisual experience.

[0087] For example, the speaker 100 can operate as follows: When the speaker 100 plays audio, sound pressure signals are generated inside or in the near-field area due to the vibration of the speaker 20. The sound pressure sensor 50, acting as a transducer, directly captures these sound pressure signals and converts them into corresponding electrical signals. The controller 60 analyzes these electrical signals in real time, evaluating the magnitude, frequency of change, and spectral characteristics of the sound pressure. For example, it detects the intensity of the sound pressure signal (i.e., volume), decomposes the sound pressure signal into different frequency components (such as low frequency, mid frequency, and high frequency) using a preset algorithm (such as Fast Fourier Transform), and generates control commands in real time based on the analysis results to control the driving state of multiple micro-drivers 80 and the luminous state of multiple light-emitting elements 41. The multiple light-emitting elements 41, multiple micro-drivers 80, and their corresponding multiple light guides can be pre-grouped in different ways, such as into three groups based on low frequency, mid frequency, and high frequency. For example, when a low-frequency drumbeat appears, the light-emitting element 41 corresponding to the low frequency can be red or orange, and the light guide column corresponding to the low frequency will quickly "jump" upward (with a large vibration amplitude and a low frequency). When a high-frequency human voice sounds, the light-emitting element 41 corresponding to the high frequency can be blue or purple, and the light guide column corresponding to the high frequency will vibrate rapidly and slightly (with a small vibration amplitude and a high frequency).

[0088] The light emitted by the multiple light-emitting elements 41 first enters the bottom of the multiple light guide pillars. At the same time, after receiving the control command from the controller 60, the multiple micro-drivers 80 start within milliseconds, driving the corresponding light guide pillars to perform linear reciprocating motion with different amplitudes and frequencies.

[0089] Because the light guide is transparent, its movement along its length alters the path and transmission effect of light. For example, when the brightness of the light-emitting element 41 remains constant, if the light guide "jumps" to its highest point—that is, when it is closest to the light-emitting element 41—the reflection loss of the light emitted by the light-emitting element 41 entering the light guide is minimal, resulting in the highest brightness of the light subsequently transmitted through the light-emitting surface 31. Conversely, when the light guide is at its lowest point, the brightness of the light transmitted through the light-emitting surface 31 is the lowest. Furthermore, if the light-incident end of the light guide (the end corresponding to the light-emitting element 41) is optically designed (such as a convex lens, concave lens, or wedge structure), the movement of the light guide along its length changes the focal or collimated position of the light-emitting element 41 relative to that light-incident end, thereby altering the initial angular distribution of light entering the light guide and causing changes in the light transmitted through the light-emitting surface 31 (such as creating brightness gradients or color separation). For example, when the light emitted by the light-emitting element 41 travels, it passes through the transparent diaphragm of the passive radiator 111. The intense vibrations generated by the passive radiator 111 under low-frequency sound pressure cause rhythmic refraction and distortion of the transmitted light, creating a dynamic vibration sensation in the light and shadow observed by the user, thus integrating the "vibration" attribute of sound into the light effect. In this way, the physical movement of the light guide column can be presented through changes in the brightness, color, or displacement of the light, thereby transforming abstract sound waves into dynamic three-dimensional physical light effects. These effects are ultimately presented to the user through the light-emitting surface 31 of the transparent module 30 and the transparent element 70, achieving the effect of the light dynamically changing with the sound pressure. Three-dimensional physical light effects refer to the light effects generated based on the physical movement of the light guide column in the three-dimensional world.

[0090] When multiple light guide columns rise and fall according to the sound pressure, this light effect will echo on the back of the speaker 100 through the optical connection between the transparent module 30 and the transparent part 70, making the entire product seem to "breathe" and "rhythm" with the sound, further enhancing the user's sense of immersion, and making the visualization of sound no longer limited to a single area, but a complete, three-dimensional work of light and shadow.
