[0022] To more clearly illustrate the technical solutions of the embodiments of this specification, the following briefly describes the drawings required for describing the embodiments. Obviously, the drawings described below are merely examples or embodiments of this specification. Those skilled in the art can apply this specification to other similar scenarios based on these drawings without inventive effort. Unless otherwise apparent from the context or otherwise noted, the same reference numerals in the figures represent the same structure or operation.

[0023] Existing passive radiators can only be used to improve the sound quality of the speakers, with a single function. In addition, passive radiators occupy a large area on the outer surface of the speakers, which cannot improve the aesthetics of the outer surface of the speakers.

[0024] In light of this, some embodiments of this specification contemplate an improved speaker system in which the counterweight of a passive radiator is translucent. By utilizing the internal light source of the speaker system in conjunction with the counterweight, different lighting effects can be created. This enhances the functionality of the passive radiator and improves the speaker's appeal and aesthetics.

[0025] Figure 1 It is a structural diagram of the speakers according to some embodiments of this specification. Figure 2 It is a schematic structural diagram of a passive radiator according to some embodiments of this specification.

[0026] like Figure 1 As shown, the speaker 100 may include a passive radiator 110 and a speaker cavity 120. The passive radiator 110 may be connected to the speaker cavity 120.

[0027] The sound cavity 120 refers to the shell structure of the sound system 100. In some embodiments, a cavity 122 may be provided in the sound cavity 120, and an active sound generating unit may be provided in the cavity 122.

[0028] An active sound-producing unit refers to a structure that can produce sound on its own. For example, it can be at least one of a speaker and a loudspeaker. In some embodiments, the active sound-producing unit can be connected to the sound cavity 120 in a variety of ways, such as at least one of bonding, snapping, and threading.

[0029] In some embodiments, the outer surface of the acoustic cavity 120 may include various structures, such as at least one of a prism and a cylinder. In some embodiments, the cavity 122 may be adapted to the structure of the outer surface of the acoustic cavity 120 .

[0030] In some embodiments, the acoustic cavity 120 can be made of a variety of materials, such as at least one of metal, plastic, and wood.

[0031] Passive radiator 110 can be used to adjust the sound of speaker 100. The active sound-generating unit within speaker 100 produces sound, causing the air within cavity 122 to vibrate. This air vibration drives the passive radiator 110 to resonate, causing it to passively generate sound. Using passive radiator 110 can, for example, change the timbre of speaker 100. Resonance means that the passive radiator 110 vibrates synchronously with the air at the same frequency.

[0032] In some embodiments, the passive radiator 110 can control the amplitude of vibration based on its own weight. Different weights can produce different amplitudes, thereby emitting different sounds.

[0033] In some embodiments, as Figure 1As shown, at least a portion of the passive radiator 110 may be connected at the opening of the cavity 122. In some embodiments, the passive radiator 110 may cover the opening of the cavity 122.

[0034] In some embodiments, the passive radiator 110 and the acoustic cavity 120 may be connected in various ways, such as at least one of bonding, clamping, and threading.

[0035] In some embodiments, at least a portion of the passive radiator 110 may be elastic. For example, at least a portion of the passive radiator 110 may be made of an elastic material. In another example, at least a portion of the passive radiator 110 may include an elastic structure. The elastic portion of the passive radiator 110 may deform elastically in response to air vibrations, allowing the passive radiator 110 to vibrate synchronously with the air.

[0036] In some embodiments, the passive radiator 110 may be a body of revolution structure. In some embodiments, the opening of the cavity 122 may be circular. In some embodiments, the passive radiator 110 may be coaxial with the opening of the cavity 122.

[0037] In some embodiments, as Figure 1 、 Figure 2 As shown, the passive radiator 110 may include a counterweight 111, a bracket 112, and a rubber edge 113. The counterweight 111 may be connected to the rubber edge 113. The rubber edge 113 may be provided on the bracket 112. The bracket 112 may be connected to the sound cavity 120.

[0038] In some embodiments, the counterweight 111 may be a rotating body structure. The bracket 112 and the rubber edge 113 may be annular structures.

[0039] In some embodiments, at least a portion of one side surface of the counterweight 111 may be connected to at least a portion of one side surface of the adhesive edge 113. In some embodiments, at least a portion of one surface of the adhesive edge 113 may be connected to at least a portion of one surface of the bracket 112.

[0040] In some embodiments, one of the surfaces of the counterweight 111, the rubber edge 113, and the bracket 112 may include at least an outer end surface, an inner end surface, an outer annular surface, and an inner annular surface. Figure 1 The inner end surface is the end surface along the axial direction of the passive radiator 110 and close to the acoustic cavity 120.

The inner annular surface is the surface surrounding the axial direction of the passive radiator 110 and located on the inside of the ring.

[0041] In some embodiments, a sealed connection may be formed between the counterweight 111 and the adhesive edge 113 , and between the adhesive edge 113 and the bracket 112 .

[0042] In some embodiments, the passive radiator 110 may close the opening of the cavity 122 .

[0043] The counterweight 111 is a structure having a certain weight. In some embodiments, the counterweight 111 can add weight to the passive radiator 110. In some embodiments, the weight of the counterweight 111 can be varied to change the weight of the passive radiator 110. For example, the counterweight 111 can include multiple connectable structures. By connecting different numbers of connectable structures, counterweights 111 with different weights can be formed.

[0044] In some embodiments, the counterweight 111 can be made of a variety of materials, such as at least one of metal and plastic.

[0045] In some embodiments, at least a portion of the counterweight 111 may protrude into the interior of the acoustic cavity 120. The protruding portion may include a variety of shapes. For example, at least one of a prism shape and a curved surface shape. The curved surface shape may include at least a portion of a spherical surface.

[0048] In some embodiments, the first connecting portion 1112 can serve as a mounting base for mounting the light-transmitting portion 1111 and providing support for the light-transmitting portion 1111 .

[0049] In some embodiments, the first connecting portion 1112 may be annular in structure, and the light-transmitting portion 1111 may be disposed in the middle of the first connecting portion 1112 .

[0050] In some embodiments, the first connection portion 1112 and the light-transmitting portion 1111 may be connected in various ways, such as at least one of bonding, clamping, and integral molding.

[0051] In some embodiments, at least a portion of the counterweight 111 can be elastic. For example, the first connecting portion 1112 can be elastic. When the passive radiator 110 resonates due to vibrations in the air, the first connecting portion 1112 can elastically deform, causing the passive radiator 110 to vibrate synchronously with the air.

[0052] In some embodiments, the first connecting portion 1112 can be made of an elastic material. For example, an elastic plastic or the like.

[0053] In some embodiments, the first connecting portion 1112 can include an elastic structure. For example, the elastic structure can include at least one of a C-shaped structure, a U-shaped structure, a V-shaped structure, or the like. Here, the cross section of the first connecting portion 1112 refers to a section of the first connecting portion 1112 that is cut by a plane passing through an axis of the first connecting portion 1112.

[0054] Making at least part of the weight 111 elastic can make the weight 111 resonate more easily, thereby making it easier for the passive radiator to emit sound.

[0055] The light-transmitting portion 1111 refers to a structure that can transmit light.

[0056] In some embodiments, the sound cavity 120 can be provided with a light source 121. The light source 121 can be configured to emit light to the light-transmitting portion 1111.

[0059] For more information about the inner end surface and the outer end surface, please refer to the relevant description in the foregoing.

[0060] In some embodiments, at least part of the light-transmitting portion 1111 can be made of a transparent material. For example, a transparent plastic or the like.

[0061] In some embodiments, the light source 121 can include an LED lamp. In some embodiments, the LED lamp can emit light of various colors. For example, at least one of red, yellow, blue, green, white, or the like.

[0062] In some embodiments, the LED lamp can be a sound-controlled LED lamp.

[0063] In some embodiments, the LED lamp can be controlled by the sound emitted by the active sound unit and / or the passive radiator 110. In some embodiments, the sound emitted by the active sound unit and / or the passive radiator 110 can control the sound-controlled LED lamp to at least one of the functions of turning on, turning off, changing the brightness of illumination, changing the color, etc. Among them, the sound can include different loudness of sound. Different loudness of sound can correspond to different brightness and / or color of LED lamp.

[0066] The metal layer refers to a layered structure made of metal material. For example, a metal plate is used. The metal layer can be used to increase the weight of the light-transmitting part 1111.

[0067] In some embodiments, the metal layer can be used to shield at least part of the light emitted by the light source 121, so that the remaining light can form different shapes or patterns after penetrating the light-transmitting part 1111.

[0068] The plastic layer refers to a structure made of plastic material. For example, a transparent plastic is used.

[0071] In some embodiments, the user can change the weight of the passive radiator 110 by changing the number of metal layers in the clamping groove, so as to make the passive radiator 110 produce sound of different timbre.

[0072] In some embodiments, the metal layer can also be disposed on the surface of the plastic layer. For example, it can be disposed on the outer end surface of the plastic layer. In some embodiments, at least one light-transmitting hole can be provided in the metal layer. The light-transmitting hole can have a variety of shapes or patterns. For example, at least one of the shapes of letters and cartoons can be provided. After the light emitted by the light source 121 passes through the plastic layer, some of the light can be blocked by the metal layer, while some of the light can pass through the light-transmitting hole, thereby illuminating different shapes or patterns.

[0073] In some embodiments, the metal layer can be rotatably connected to the plastic layer. In some embodiments, the center of rotation of the metal layer can be coaxial with the axis of the plastic layer. Rotating the metal layer can change the angle of the light-transmitting aperture relative to the center of rotation, thereby changing the angle of the shape or pattern of the light emitted. In some embodiments, the metal layer can include two layers. The two metal layers can rotate relative to each other, so that the light-transmitting apertures in the two metal layers can be combined to form different shapes or patterns.

[0074] In some embodiments, the outer end surface of the plastic layer may be arc-shaped, for example, spherical, etc. In some embodiments, the shape of the metal layer may be adapted to the outer end surface of the plastic layer.

[0128] In some embodiments, the outer annular surface of the elastic portion 1133 may be connected to the inner annular surface of the second connecting portion 1131 . The inner annular surface of the elastic portion 1133 may be connected to the outer annular surface of the third connecting portion 113 .

[0129] In some embodiments, the elastic portion 1133 may be connected to the second connection portion 1131 and the third connection portion 1132 in various ways, such as at least one of bonding, clamping, and integral molding.

[0130] In some embodiments, the elastic portion 1133 may be elastic. When the passive radiator 110 is affected by the vibration of the air and resonates, the elastic portion 1133 may be elastically deformed, causing the passive radiator 110 to vibrate synchronously with the air.

[0131] In some embodiments, the elastic portion 1133 may be made of an elastic material, such as at least one of elastic plastic and rubber.

[0132] In some embodiments, the elastic portion 1133 may include an elastic structure. For example, the cross-section of the elastic portion 1133 may be designed to be at least one of a C-shape, a U-shape, a V-shape, etc. The cross-section of the elastic portion 1133 refers to a cross-section of the elastic portion 1133 cut by a plane passing through the axis of the elastic portion 1133.

[0133] In some embodiments, an LED light strip (not shown) may be provided on the outer side of the adhesive edge 113 .

[0134] An LED light strip refers to a strip-shaped structure made of LED lights. In some embodiments, the LED light strip can be annular. In some embodiments, the LED light strip can be coaxial with the adhesive edge 113. In some embodiments, the LED light strip can be disposed on the outer surface of the adhesive edge 113. For example, it can be disposed on the outer end surface of at least one of the elastic portion 1133, the second connecting portion 1131, or the third connecting portion 113.

[0135] In some embodiments, the adhesive edge 113 and the LED light strip can be connected in various ways, for example, at least one of bonding and clamping.

[0136] In some embodiments, the LED light strip can be a strip of voice-activated LED lights. In some embodiments, the LED light strip can include multiple voice-activated LED lights, which can be combined to form the LED light strip. For example, the multiple voice-activated LED lights can be arranged along the circumference of the adhesive edge 113, outside the adhesive edge 113.

[0137] Voice-controlled LED lights are those that can be controlled by sound. For example, they can be used to turn the LED light on or off, change brightness, or change color. The sounds can vary in volume, and the varying loudness of the sounds can correspond to varying brightness and / or color of the LED light.

[0138] By installing an LRD light strip on the outside of the rubber edge, different lighting effects can be created using the LRD light strip, making it easier for users to identify the location of the speaker in a dark environment. By using voice-activated LED lights, the sound emitted by the speaker itself can be used to control the voice-activated LED lights, making them adaptively change brightness and / or color according to the rhythm of the speaker sound, enhancing the visual effect of the speaker.

[0139] Some embodiments of this specification provide speakers that incorporate a light source and utilize a light-transmitting counterweight, creating a light effect. This enhances the functionality of the counterweight, adds to the audio's ambiance and appeal, and improves the user experience. The counterweight itself is constructed of a light-transmitting material, eliminating the need for additional structure and reducing production costs.

[0140] Figure 3 Schematic diagram of the inner end surface structure of a passive radiator according to some embodiments of this specification.

[0141] In some embodiments, as Figure 1 、 Figure 3 As shown, at least a portion of the inner end surface of the light-transmitting portion 1111 includes a convex surface.

[0142] The convex surface 11111 refers to the inner end surface of the light-transmitting portion 1111 along the axial direction of the passive radiator (for example, Figure 1 in the Z direction), a surface protruding toward the interior of the acoustic cavity 120.

[0143] By providing the convex surface 11111, the light emitted by the light source 121 can be refracted by the convex surface 11111 and then pass through the light-transmitting portion 1111. The light emitted by the light source 121 can produce different degrees of refraction when passing through the convex surface 11111 from different positions, so that the light emitted by the light-transmitting portion 1111 can form various visual effects.

[0144] In some embodiments, the convex surface 11111 may be an outer surface of a body of revolution. In some embodiments, the convex surface 11111 may be coaxial with the light-transmitting portion 1111 .

[0145] In some embodiments, the convex surface 11111 may include various shapes, for example, at least one of a flat surface and a curved surface.

[0146] In some embodiments, the convex surface 11111 may include a plurality of transmissive surfaces 11112. The plurality of transmissive surfaces 11112 may allow at least a portion of the counterweight 111 to protrude toward the interior of the acoustic cavity 120, forming a prismatic structure.

[0147] The transmissive surface 11112 refers to a surface through which light can pass. When light passes through different transmissive surfaces 11112, the angles of refraction may be the same or different, and the directions of refraction may be the same or different.

[0148] In some embodiments, the transmissive surface 11112 can be formed by various methods, for example, by performing at least one of machining, integral molding, and pasting on the convex surface 11111.

[0149] In some embodiments, two adjacent transmissive surfaces 11112 may be at an angle to each other, resulting in different refraction effects on light by the two adjacent transmissive surfaces 11112. This allows the use of different transmissive surfaces to create a variety of different refraction effects on light, thereby enhancing the visual effect created by light passing through the translucent portion 1111.

[0150] Figure 4 It is a schematic structural diagram of a transmission surface according to some embodiments of this specification.

[0151] In some embodiments, the transmissive surface 11112 can be a convex curved surface. Convex means protruding toward the interior of the acoustic cavity 120. When light strikes the same transmissive surface 11112, different refraction effects can be created at different locations, further enhancing the visual effect created by light passing through the translucent portion 1111.

[0152] In some embodiments, the arc surface may include multiple types, for example, at least one of a spherical surface and a cylindrical surface.

[0153] By forming the inner end surface of the light-transmitting portion into a convex surface, the visual effect formed after the light is projected can be further enhanced, the interest of the audio can be further improved, and the user experience can be improved.

[0154] Figure 5 It is a schematic structural diagram of a passive radiator according to some embodiments of this specification.

[0155] In some embodiments, as Figure 5 As shown, a printed layer 130 may be provided on the outer surface of the light-transmitting portion 1111 .

[0156] The printed layer 130 is a planar structure disposed on the outer side of the light-transmitting portion 1111. In some embodiments, the printed layer 130 may include a variety of graphics, such as at least one of animals, plants, and cartoons.

[0157] In some embodiments, the printed layer 130 can be disposed on the outer surface of the light-transmitting portion 1111 in various ways, such as at least one of pasting, coating, and printing.

[0158] In some embodiments, the printed layer 130 can include multiple colors. In some embodiments, the printed layer 130 can be opaque, blocking at least some light, thereby creating a shadow corresponding to the printed layer. In some embodiments, the printed layer 130 can be translucent, allowing light to pass through the printed layer 130, thereby creating an image corresponding to the shape and color of the printed layer 130.

[0159] By setting the printed layer, the illumination effect of light can be changed, thereby enhancing the interest of the sound.

[0160] Figure 6 It is a schematic structural diagram of a passive radiator according to some embodiments of this specification.

[0161] In some embodiments, as Figure 6 As shown, a decorative structure 140 may be provided on the outer surface of the light-transmitting portion 1111 .

[0162] The decorative structure 140 is a three-dimensional structure provided on the outer side of the light-transmitting portion 1111. The decorative structure 140 can decorate the light-transmitting portion 1111 and enhance the beauty of the light-transmitting portion 1111.

[0163] In some embodiments, the decorative structure 140 may include a variety of three-dimensional structures, such as at least one of animals, plants, and cartoons.

[0164] In some embodiments, the decorative structure 140 can be disposed on the outer side of the light-transmitting portion 1111 in various ways. For example, at least one of pasting, clamping, screwing, and the like.

[0165] In some embodiments, the decorative structure 140 can be elastically connected with the light-transmitting portion 1111. When the passive radiator 110 synchronously vibrates under the action of air vibration, the light-transmitting portion 1111 can drive the decorative structure 140 to synchronously vibrate. Thus, the decorative structure 140 can swing, sway, or the like relative to the light-transmitting portion 1111. The interest of the sound can be enhanced.

[0166] In some embodiments, the decorative structure 140 can be connected with the light-transmitting portion 1111 through an elastic structure. The elastic structure can include at least one of a spring, a spring sheet, and the like.

[0167] In some embodiments, the decorative structure 140 can be connected with the light-transmitting portion 1111 through an elastic material. The elastic material can include at least one of rubber, silicone, and the like.

[0168] In some embodiments, the decorative structure 140 can have elasticity. For example, the decorative structure 140 can be made of an elastic material. The elastic material can include at least one of rubber, silicone, and the like. For another example, the decorative structure 140 can be made of an elastic structure. The elastic structure can include a spring and the like. For another example, the decorative structure 140 can simulate a butterfly including a body part and two wing parts. The body part can be elastically connected with the light-transmitting portion 1111, and the two wing parts can be elastically connected with the body part, respectively.

[0169] By making the decorative structure 140 have elasticity, when the decorative structure 140 follows the light-transmitting portion 1111 to synchronously vibrate, the decorative structure 140 can also elastically deform itself, thus simulating various shapes, and the interest of the sound can be further enhanced.
