[0020] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0021] In the description of this utility model, it should be understood that the terms "upper", "lower", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0022] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0023] like Figures 1 to 3 As shown, in one embodiment, the speaker 100 includes a housing 1, a speaker 2, a light source 3, a pattern generating unit 4, a driving unit 5, and a control unit; the speaker 2, the light source 3, the pattern generating unit 4, the driving unit 5, and the control unit are all disposed inside the housing 1; the speaker 2 is used to output sound to the outside of the housing 1; the light source 3 is used to project light onto the pattern generating unit 4; the housing 1 has a light-transmitting area 11; the pattern generating unit 4 is used to pattern the light emitted by the light source 3 to obtain a light spot pattern, and is used to project the light spot pattern from the light-transmitting area 11 out of the housing 1; the driving unit 5 is used to drive the pattern generating unit 4 to rotate, so that the light spot pattern projected from the light-transmitting area 11 rotates; the control unit is electrically connected to the speaker 2, the light source 3, and the driving unit 5.

[0024] In the existing technology, in order to use the speaker 100 and the spotlight together, the user needs to purchase the speaker 100 and the spotlight separately before they can be used together. This separate purchase method leads to inconvenience in using the speaker 100 and the spotlight. Moreover, since the speaker 100 and the spotlight are two independent objects, they need to be installed and placed in appropriate positions separately during use, which also leads to inconvenience in using the speaker 100 and the spotlight.

[0025] In this embodiment, through the cooperation of the light source 3, the pattern generation unit 4, and the driving unit 5, the speaker 100 can project a corresponding light spot pattern to the outside. At this time, the light source 3, the pattern generation unit 4, and the driving unit 5 in the speaker 100 are equivalent to forming a projection lamp. In this way, the speaker 100 can both output sound and project light spot patterns to the outside, which is equivalent to integrating the projection lamp and the speaker 100 together, or equivalent to adding a projection lamp on the basis of the existing speaker 100.

[0026] Thus, purchasing only the speaker 100 of this embodiment is equivalent to simultaneously purchasing both the speaker 100 and the projector in the prior art. Furthermore, in use, simply installing the speaker 100 of this embodiment in a suitable location is equivalent to installing both the speaker 100 and the projector in a suitable location. Therefore, the setup of this embodiment provides convenience for users who wish to combine the speaker 100 and the projector.

[0027] Furthermore, in existing technologies, when the speaker 100 and the projector are used together, their controllers need to be connected for communication so that the audio output from the speaker 100 matches the light spot pattern output from the projector, which is a rather cumbersome operation. In this embodiment, however, the speaker 100 and the projector are integrated together, both controlled by a control unit. Thus, in this embodiment, the speaker 100 can be pre-programmed with the corresponding control program in the control unit at the factory to control the operation of the speaker 100 and the projector (i.e., the light source 3 and the drive unit 5). This eliminates the need for the separate matching connection operation between the speaker 100 and the projector controller as in existing technologies, making it more convenient for users.

[0028] It should be understood that the purpose of electrically connecting the control unit to the speaker 2, the light source 3, and the drive unit 5 is primarily to control the operation of the speaker 2, the light source 3, and the drive unit 5 through the control unit. The control unit can be a microcontroller, etc., which is an existing configuration. Furthermore, the principle and method by which the control unit controls the operation of the speaker 2, the light source 3, and the drive unit 5 can also be existing technology.

[0029] In addition, speaker 2 can also be an existing design.

[0030] In one application scenario, the light spot pattern can be a pattern such as "water ripples" or "heart-shaped pattern".

[0031] In one embodiment, the light-transmitting area 11 can focus the light spot pattern. This allows the light spot pattern to be more concentratedly illuminated within a certain range of the target object (such as a wall).

[0032] like Figure 2 and Figure 3As shown, in one embodiment, the outer casing 1 includes a housing 12 and a light-concentrating element 13; the housing 12 has a receiving cavity 121, and a light-emitting port 122 is formed on the outer surface of the receiving cavity 121; the speaker 2, the driving unit 5, the light source 3, and the pattern generating unit 4 are all disposed within the receiving cavity 121; the light-concentrating element 13 is connected to the housing 12 and closes the light-emitting port 122; at least a portion of the light-concentrating element 13 is a light-transmitting area 11. This facilitates the setting of the light-transmitting area 11.

[0033] The light-transmitting area 11 is opposite to the light-emitting port 122. The light emitted from the light-transmitting area 11 will also be emitted from the light-emitting port 122.

[0034] In one embodiment, the light-concentrating element 13 may be bonded to the housing 12.

[0035] In one embodiment, the housing 12 also has a corresponding partition 14 to divide the receiving cavity 121 into different subspaces, and the speaker 2 and the projection lamp (i.e., the combination structure of the light source 3, the pattern generation unit 4 and the driving unit 5) can be placed in different subspaces to avoid interference.

[0036] In one embodiment, the receiving cavity 121 has a first subspace 123 and a second subspace 124, which are spaced apart and separated by corresponding partitions 14. Furthermore, the first subspace 123 is located below the second subspace 124, the speaker 2 is located within the first subspace 123, and the light source 3, the pattern generating unit 4, and the driving unit 5 are all located within the second subspace 124.

[0037] In one embodiment, the light-emitting port 122 is the upper opening of the receiving cavity 121, located on the upper surface of the housing 12. Moreover, the light-emitting port 122 can also be regarded as an opening formed by the second subspace 124 on the outer surface of the housing 12. This facilitates the projection of the light source 3 into the space above the speaker 100 to project a light spot pattern.

[0038] like Figure 3 and Figure 4 As shown, in one embodiment, the light-concentrating element 13 includes a connecting portion 131 and a light-concentrating portion 132; the connecting portion 131 is located within the receiving cavity 121 and is connected to the housing 12; the light-concentrating portion 132 extends out of the housing 1 from the light-emitting port 122; at least a portion of the area where the light-concentrating portion 132 extends out of the housing 1 is a light-transmitting area 11. This allows the light-concentrating element 13 to be more firmly connected to the housing 12.

[0039] In one embodiment, the light-concentrating part 132 is a Fresnel lens, which can improve the light-concentrating effect of the light-concentrating part 132.

[0040] like Figure 4 and Figure 5As shown, in one embodiment, the light-concentrating part 132 is a hemispherical shell structure, and the recess of the shell structure is connected to the receiving cavity 121.

[0041] At this time, the outer surface of the focusing part 132 includes a spherical surface 133 and a bottom surface 134, which intersect. A spherical groove 135 is provided on the bottom surface 134, and the spherical groove 135 is concentric with the spherical surface 133. Furthermore, the inner surface of the spherical groove 135 has a corresponding structure to enable the focusing part 132 to form a Fresnel lens. This reduces weight and material costs, and since the light spot pattern is emitted from the spherical surface 133 of the focusing part 132, the projection effect of the light spot is also improved.

[0042] In one embodiment, the diameter of the bottom surface 134 is greater than or equal to the maximum diameter of the sphere 133.

[0043] like Figure 4 and Figure 5 As shown, in one embodiment, the connecting portion 131 includes a connecting wall 136 and a bottom wall 137, wherein the connecting wall 136 is connected to the side of the focusing portion 132; the connecting wall 136 has an annular structure that surrounds the focusing portion 132; the bottom wall 137 is connected to the connecting wall 136 and is located on the side of the connecting wall 136 away from the focusing portion 132. This can improve the strength of the focusing element 13.

[0044] In addition, the bottom wall 137 is a ring structure that surrounds the connecting wall 136, and the bottom wall 137 and the connecting wall 136 can be coaxially arranged.

[0045] When the light-concentrating part 132 is a hemispherical shell structure, the lower surface of the connecting wall 136 can be flush with the bottom surface 134, the upper surface of the connecting wall 136 intersects with the spherical surface 133, and the height of the connecting wall 136 relative to the bottom surface 134 is less than the height of the vertex of the spherical surface 133 relative to the bottom surface 134. In addition, the bottom wall 137 is connected to the lower surface of the connecting wall 136, and in the radial direction of the bottom surface 134, the bottom wall 137 is located on the side of the connecting wall 136 away from the light-concentrating part 132.

[0046] When the connecting part 131 is bonded to the housing 12, it can specifically mean that the upper surface of the connecting wall 136 is bonded to the housing 12.

[0047] In addition, the circumference of the connecting wall 136 is in contact with the housing 12 to seal the light outlet 122. In some scenarios, after the light-concentrating part 132 passes through the light outlet 122, a corresponding sealing object can also be provided between the light-concentrating part 132 and the housing 12 to achieve a sealed connection between the two.

[0048] like Figure 6As shown, in one embodiment, the driving unit 5 includes a driving part 51 and a rotating part 52. The rotating part 52 connects the driving part 51 and the pattern generating unit 4. The driving part 51 drives the rotating part 52, causing the rotating part 52 to drive the pattern generating unit 4 to rotate. The driving part 51 and the pattern generating unit 4 are spaced apart. The surface of the pattern generating unit 4 near the driving part 51 is the light-incident surface 41, and the surface of the pattern generating unit 4 away from the driving part 51 is the light-exiting surface 42. The light source 3 is located between the driving part 51 and the pattern generating unit 4. The light emitted by the light source 3 enters the pattern generating unit 4 from the light-incident surface 41 and exits the pattern generating unit 4 from the light-exiting surface 42 to form a light spot pattern.

[0049] By placing the light source 3 between the pattern generation unit 4 and the driving unit 51, the space between the two can be fully utilized, thereby reducing the size of the entire speaker 100.

[0050] After assembly, the drive unit 51 can be mounted on the housing 12 or the partition 14.

[0051] In addition, the light-emitting surface 42 faces the light-transmitting area 11, so that the pattern generating unit 4 can project the light spot pattern emitted from it onto the light-transmitting area 11, and then the light spot pattern can be emitted from the light-transmitting area 11.

[0052] In one embodiment, the drive unit 5 is a rotary motor, such as a servo motor. The drive part 51 is the motor body, and the rotating part 52 is the motor spindle. The body includes a housing and components such as a stator and rotor disposed within the housing.

[0053] like Figure 6 As shown, in one embodiment, the pattern generation unit 4 is a diffractometer, which is used to pattern the light passing through it to obtain a light spot pattern. This facilitates the setting of the pattern generation unit 4 and reduces its cost.

[0054] The diffractor has an incident surface 41 and an exit surface 42. The light emitted from the light source 3 enters the diffractor from the incident surface 41 and then exits the diffractor from the exit surface 42. The exit surface 42 has corresponding pits and other structural features so that the light forms a corresponding light spot pattern after exiting the exit surface 42.

[0055] In addition, the diffraction plate is an existing design.

[0056] Furthermore, when the driving unit 5 drives the diffractor to rotate, the axis around which the diffractor rotates can be parallel to the arrangement direction of the incident light surface 41 and the exit light surface 42. For example, when the incident light surface 41 is a plane, this axis can be perpendicular to the incident light surface 41.

[0057] like Figure 6As shown, in one embodiment, the light source 3 is connected to the drive unit 51. This allows the drive unit 51 to support the light source 3, eliminating the need for an additional structure to support the light source 3, thereby reducing the number of parts and facilitating assembly.

[0058] In one embodiment, the light source 3 can emit light of multiple colors, which can improve the light projection effect.

[0059] like Figure 6 As shown, in one embodiment, the light source 3 includes a circuit board 31 and an RGB lamp 32; the RGB lamp 32 is electrically connected to the circuit board 31 so that the circuit board 31 supplies power to the RGB lamp 32 so that the RGB lamp 32 emits light.

[0060] The circuit board 31 is connected to the control unit, which can control the power supply of the RGB lamp 32 through the circuit board 31.

[0061] In one embodiment, the circuit board 31 is a PCB board connected to the driver unit 51, and the RGB lamp 32 is connected to the side of the circuit board 31 away from the driver unit 51.

[0062] It should be understood that the above-mentioned settings can also be replaced in other ways, such as: In other embodiments, the pattern generation unit 4 may also be a mask with a corresponding pattern or a DMD (Digital Micromirror Device). When the pattern generation unit 4 is a DMD, the control unit is also electrically connected to the pattern generation unit 4 for controller operation.

[0063] In other embodiments, the light-transmitting area 11 may not have a light-focusing function. In this case, the light-transmitting area 11 may be a through hole or a transparent plate.

[0064] In other embodiments, the connecting portion 131 abuts against the housing 12 on the side near the focusing portion 132; the speaker 100 also includes a baffle located within the receiving cavity 121 and connected to the housing 12; the baffle abuts against the side of the connecting portion 131 opposite to the focusing portion 132. In this embodiment, the focusing element 13 is pressed against the housing 12 by the baffle, thereby achieving the connection between the focusing element 13 and the housing 12, which facilitates the connection between the focusing element 13 and the housing 12. Furthermore, the connection portion 131 abutting against the housing 12 actually refers to the upper surface of the connecting wall 136 abutting against the housing 12, and the connection portion 131 abutting against the baffle actually refers to the lower surface of the bottom wall 137 abutting against the baffle.

[0065] In other embodiments, the light-concentrating element 13 may not be part of the housing 1. In this case, the light-transmitting area 11 may be at least a portion of the light-emitting port 122. Additionally, in this embodiment, the light-concentrating element 13 may be fixed to the housing 12; or, the light-concentrating element 13 may be connected to the driving unit 5 so that the driving unit 5 can drive the light-concentrating element 13 and the pattern generating unit 4 to rotate simultaneously. In this case, the light-concentrating element 13 and the pattern generating unit 4 may be relatively fixed and do not undergo relative movement.

[0066] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0067] The above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model, and should all be included within the protection scope of this utility model.
