DETAILED DESCRIPTION

The technical solutions in the embodiments of the present disclosure are clearly and completely described in the following with reference to the accompanying drawings. It is obvious that the described embodiments are only part of the embodiments of the present disclosure, but not all embodiments. All other embodiments obtained by those skilled in the art according to the embodiments of the present disclosure without creative efforts are within the protection scope of the present disclosure.

A sound box is also called a speaker system. A sound box is a device that converts an audio signal into sound (i.e., acoustic signal) . In general, a sound box refers to a mainframe of a sound box or a subwoofer box with its own power amplifier. After the audio signal is amplified, the sound is played back by the sound box itself and the sound is made louder. The sound box is the terminal of the entire sound system. The sound box converts the audio electrical energy into the corresponding sound energy and radiate it into the space. The sound box is an extremely important part of the sound system, and the sound box is responsible for the task of converting electrical signals into acoustic signals for direct listening.

The existing sound boxes are generally composed of electronic devices and structural devices such as speaker (s) , a box body, a frequency divider, and the like. The speaker (s) , the frequency divider and the like are integrated inside the box body. In order to increase the visual experience, some box body is also provided with an optical instrument such as a lighting device. For example, LED lights and the like are directly disposed in the box body, or LED lights are disposed on the outer edge of the box body.

However, if the lighting device, the speaker, the frequency divider, and the like are integrated into the box body, when the speaker is operating, the generated vibration may easily cause damages or failures of the optical instrument, the electronic device, and the structural device in the box body.

In order to solve the above problems, the present disclosure provides a lighting device with a built-in speaker. The lighting device with the built-in speaker can also be referred as an audio lighting device or a speaker light.

FIG. 1 is a structural diagram of an embodiment of a lighting device with built-in speaker consistent with the disclosed embodiments. FIG. 2 is a cross-sectional view taken along the Y-Y line in FIG. 1; and FIG. 3 is a cross-sectional view taken along the Z-Z line in FIG. As shown in FIG. 1 to FIG. 3, the lighting device with built-in speaker provided in an exemplary embodiment includes: an audio component 10, a housing 20, a lamp cover 30, and a lighting component 40.

The audio component 10 includes a speaker 101 and a sound box 102. The interior of the sound box 102 is provided with a sound chamber 103 with an opening, and the speaker 101 is disposed at the opening of the sound chamber 103.

The housing 20 has an opening 201 at one end thereof, and the lamp cover 30 is connected to the opening 201 of the housing 20. The lamp cover 30 and the housing 20 together encloses a closed chamber.

In some embodiments, the lamp cover 30 has a threaded connection with the opening 201 of the housing 20. When the lighting component 40 or the audio component 10 fails, the lamp cover 30 can be conveniently detached from the housing 20 to replace the lighting component 40 or repair the audio component 10. The opening 201 has internal threads, and the connecting end of the lamp cover 30 has external threads matching the internal threads on the opening 201. After the lamp cover 30 is screwed to the opening 201 of the housing 20, the outer wall of the lamp cover 30 is flush with the outer wall of the housing 20, and beautifies the appearance. The lamp cover 30 can also be connected to the opening 201 of the housing 20 by other means, such as a snap connection, which is not limited herein.

The audio component 10 and the lighting component 40 are both located within the chamber (i.e., the chamber formed by the lamp cover 30 and the housing 20) . The lighting component 40 is located between the audio component 10 and the inner wall of the chamber. The speaker 101 is disposed toward the end of the housing 20 opposite to the opening 201. There is a sound transmission space between the speaker 101 and the housing 20 to allow the sound emitted by the speaker 101 to be transmitted to the outside of the speaker light through the housing 20.

When assembling a lighting device with built-in speaker consistent with one or more disclosed embodiments, the speaker 101 is connected to the opening of the sound chamber 103 inside the sound box 102. The speaker 101 and the sound box 102 constitute the audio component 10. The speaker 101 is disposed toward the end of the housing 20 opposite to the opening 201. A sound transmission space exists between the speaker 101 and the housing 20. The lighting component 40 is disposed in the lamp cover 30, and the lamp cover 30 is connected to the housing 20 at an outer side of the opening 201. The lamp cover 30 and the housing 20 together enclose a closed chamber. The audio component 10 and the lighting component 40 are both located in the chamber. The lighting component 40 is located between the audio component 10 and the inner wall of the chamber. For example, the audio component 10 occupies a center space of the chamber, and the lighting component 40 is located around the audio component 10 and is closer to the inner wall of the chamber than the audio component 10.

In some embodiments, the audio component 10 and the lighting component 40 are driven by a same power supply unit embedded in the speaker light. In one embodiment, the disclosed lighting device with built-in speaker can independently implement speaker function and lighting function, and the speaker function and the lighting function do not affect each other. For example, the audio component 10 and the lighting component 40 can have individual controlling mechanism (e.g., individual instruction obtaining and processing circuit) and respond to separate user controls. In another embodiment, the disclosed lighting device with built-in speaker can implement the speaker function and the lighting function simultaneously. For example, the audio component 10 and the lighting component 40 can be connected to a same controlling circuit and/or communication circuit. The communication circuit and/or the controlling circuit is configured to obtain a user instruction directed for either one or both of the audio component 10 and the lighting component 40, identify one or more actions corresponding to the user instruction, and instruct, for each action, a corresponding component for implementation (e.g., adjusting light brightness/color, adjusting volume, changing currently-playing audio content, adjusting light brightness/color based on the volume or content of the currently-playing audio content) .

When the lighting device with built-in speaker is used as a speaker, the sound emitted by the speaker 101 is transmitted out of the housing 20 through the sound transmission space between the speaker 101 and the housing 20, as shown by the arrows in FIG. 2. The sound chamber 103 inside the sound box 102 absorbs the vibration generated by the speaker 101 to reduce the damages to electronic devices and structural devices caused by vibration and ensure the normal operation of electronic devices and structural devices.

When the lighting device with built-in speaker is used as a light, the lighting component 40 located between the audio component 10 and the inner wall of a chamber is configured to emit light through the lamp cover 30. The chamber is enclosed by the lamp cover 30 and the housing 20 and the chamber is closed. Since the sound chamber 103 inside the sound box 102 absorbs the vibration generated when the speaker 101 operates, the vibration generated by the speaker 101 does not affect or has minimal effect on the operation of the lighting component 40, and thus the lighting component 40 may not be easily damaged.

The disclosed lighting device with built-in speaker provided is configured to host both of the audio component and the lighting component to respectively implement speaker function and lighting function. The speaker function and the lighting function can be independently implemented without affecting each other or simultaneously implemented. The audio component and the lighting component are located in the closed chamber enclosed by the lamp cover and the housing. The sound emitted by the speaker is transmitted out of the housing through the sound transmission space between the speaker and the housing. The sound chamber inside the sound box absorbs the vibration generated when the speaker operates to reduce/prevent the damages to electronic devices and structural devices caused by vibration to ensure the normal operation of the electronic devices and the structural devices, and to ensure that the optical instrument, the electronic device and the structural device in the speaker light are not easily damaged.

Further, in some embodiments, the sound transmission space can have a specific structure. For example, the housing 20 includes a housing cover 202 and one or more sound transmission holes 203. The housing cover 202 is located at the other end of the housing 20 opposite to the opening 201 and is located outside of the speaker 101. There is a space between the housing cover 202 and the speaker 101. The sound transmission hole (s) 203 is located on the side wall of the housing 20. The audio component 10, the side wall of the housing 20, and the housing cover 202 enclose a sound transmission space to allow the sound emitted by the speaker 101 to be transmitted out of the housing 20 through the sound transmission hole 203.

The number of the sound transmission holes 203 on the side wall of the housing 20 may be more than one. In some embodiments, the plurality of sound transmission holes 203 may be evenly disposed around the side wall of the housing 20, so that the sound emitted by the speaker 101 is uniformly transmitted out of the housing 20

Further, according to the above embodiments, in some embodiments, the thickness of the middle portion of the housing cover 202 toward the speaker 101 (e.g., a center of the speaker) is greater than the thickness of the edge portion of the housing cover 202, so that the sound transmission space is gradually enlarged from the speaker 101 (e.g., the center of the space) toward the side wall of the housing 20 (e.g., the edge of the space) to allow the sound emitted by the speaker 101 to be uniformly transmitted out of the housing 20.

Further, based on the embodiment described above, in some embodiments, the lighting device with built-in speaker provided by the present disclosure further includes a passive diaphragm 104, which is located at a side of the sound box 102 and forms part of the side wall of the sound box 102. That is, one side of the passive diaphragm 104 forms the outer wall of the sound box 102, and the other side of the passive diaphragm 104 forms the inner wall of the sound box 102.

In some embodiments, the number of the passive diaphragms 104 is more than one, and the plurality of passive diaphragms 104 are evenly spaced around the side of the sound box 102. For example, each passive diaphragm 104 may form a section of the circumferential side wall of the sound box 102, and the distance between each neighboring section of passive diaphragm 104 may be the same.

The passive diaphragm 104 is configured to enhance the bass effect of speaker 101.

There is no driving mechanism in the passive diaphragm 104, that is, the passive diaphragm 104 does not emit sound by itself. The passive diaphragm 104 is located on the side of the sound box 102 and forms a part of the side wall of the sound box 102. That is, one side of the passive diaphragm 104 forms the outer wall of the sound box 102, the other side of the passive diaphragm 104 forms the inner wall of the sound box 102. When the speaker 101 is in operation and emits sound, the vibration of the speaker 101 causes the air in the sound chamber 103 to be compressed or expanded. Under the influence of the changing air pressure, the passive diaphragm 104 vibrates to push the air outside the sound chamber 103, thereby enhancing the bass effect of the speaker 101.

Further, in some embodiments, the housing 20 and the lamp cover 30 respectively have a cylindrical shape. The plurality of sound transmission holes 203 on the side wall of the housing 20 are evenly spaced around the circular side wall of the housing 20, so that the sound emitted by the speaker 101 is uniformly transmitted out of the housing 20, thereby improving the propagation effect of the speaker 101. In one embodiment, the housing 20 is located at the bottom of the lamp cover 30. That is, the lower part of the lighting device with built-in speaker emits sound, and the upper part of the lighting device with built-in speaker emits light. In another embodiment, the housing 20 is located at the top of the lamp cover 30, the lower part of the lighting device with built-in speaker emits light, and the upper part of the lighting device with built-in speaker emits sound.

FIG. 4 is a structural diagram of a light guide lens consistent with the disclosed embodiments. FIG. 5 is a top view of the light guide lens in FIG. 4. FIG. 6 is a cross-sectional view taken along line C-C in FIG. 5. As shown in FIG. 4-6, the lighting component 40 includes a light emitting element 401 and a light guide lens 402.

The light emitting element 401 can be one or more LED lamp beads or LED chips.

In some embodiments, the light guide lens 402 is a ring column (e.g., disposed in concentric with the lamp cover 30) . The light emitting element 401 is disposed at the lower end of the light guide lens 402 (e.g., the light emitting element 401 is placed on a board contacting/supporting the lower end face of the light guide lens 402) . For example, the lower end face of the light guide lens 402 has an annular shape, the light emitting element 401 can be placed within the annular area, i.e., in between the inner circle and the outer circle. The light emitting element 401 may include multiple LED lamp beads arranged in a circle. The width of the light emitting element 401 (e.g., length of each LED lamp bead measured at a radial direction of the circle formed by the LED lamp beads ) is less than the thickness of the light guide lens 402 (e.g., difference between diameters of two concentric circles of the lower end face of the light guide lens 402) , thereby ensuring that all the light emitted by the light emitting element 401 enters the light guide lens 402. In some embodiments, the light emitting element 401 may include one or more RGB lamp beads and/or one or more white lamp beads to emit light with mixed colors. In some embodiments, the lower end face of the light guide lens 402 may not directly contact the light emitting element 401 and may be placed a little bit higher (e.g., 0.1-0.2 millimeter higher) than a top face of the light emitting element 401, preventing the lamp beads from being damaged due to collision or other impact. The lamp beads of the light emitting element 401 have an exit angle of about 120 degrees so that even there is a small gap between the lamp beads and the light guide lens 402, almost all the lights emitted by the light emitting element enter the light guide lens 402.

The light guide lens 402 includes two walls (e.g., two concentric circular walls in the axial direction that form the ring column shape) , i.e., an inner wall and an outer wall, and two faces respectively connecting the two walls at a corresponding end, i.e., an upper end face and a lower end face. The inner wall and the upper end face of the light guide lens 402 is configured for total reflection and/or diffuse reflection. That is, a light emitted onto the inner wall or the upper end face of the light guide lens 402 can be partially or completely reflected, and eventually be directed, through one or more reflections on the inner wall or the upper end face, toward the outer wall of the light guide lens 402 and the lamp cover 30. Such configuration can minimize or eliminate lights directed to the inner space of the speaker light (e.g., minimizing refraction out of the inner wall or the upper end face) , and facilitate lights to be directed to the lamp cover 30 (e.g., redirect lights emitted onto the inner wall or the upper end face using optical reflections) . In some embodiments, the light guide lens 402 is a solid body made of acrylic. In some embodiments, optical treatment can be performed on the inner wall and the upper end face of the light guide lens 402 to achieve a total reflection effect or a diffuse reflection effect. The optical treatment may include coating with specific reflective material (s) or configuring specific texture. The outer wall of the light guide lens 402 does not receive optical treatment and is configured to facilitate light refraction toward the outside.

After a light emitted by the light emitting component 401 enters the light guide lens 402, the light may be directly refracted out of the outer wall of the light guide lens 402, or may be reflected among the outer wall and the inner wall of the light guide lens 402 and eventually refracted out of the outer wall. The light may undergo one or more reflections inside the light guide lens 402 during the propagation before being emitted out of the light guide lens 402.

In some embodiments, the upper end face of the light guide lens 402 is a total reflection surface. The inner wall of the light guide lens 402 is a total reflection surface or a diffuse reflection surface. The light that propagates to the upper end face of the light guide lens 402 may be reflected again into the light guide lens 402. During the propagation, after one or more reflections at the inner wall and/or the upper end face of the light guide lens 402, the light is reflected back to the outer wall and refracted out toward the lamp cover 30.

The light emitting element 401 is configured to emit light into the light guide lens from the lower end of the light guide lens 402. The light guide lens 402 is configured to direct the light to emit out of the outer wall and toward the outside of the lamp cover 30, e.g., by reflecting the light emitted onto the inner wall and/or the upper end face of the light guide lens 402.

In some embodiments, the inner wall of the light guide lens 402 is a total reflection surface or a diffuse reflection surface formed by a frosted surface sprayed with high-gloss paint.

In some embodiments, the upper end face of the light guide lens 402 is a total reflection surface composed of high gloss paint or reflective paper.

The propagation of the light emitted by the light emitting element 401 is completed in the light guide lens 402, so that the overall space occupied by the lighting component 40 is relatively small and is suitable for a lighting device with built-in speaker with a narrow spatial structure or a very light and thin lighting device with built-in speaker, thereby reducing the overall volume of the lighting device with built-in speaker.

The light guide lens 402 is a ring column. The light emitted from the light emitting element 401 can achieve a 360-degree uniform illumination through the lamp cover 30. The brightness of the lighting component 40 is ensured to be the same at any degree. Because the light emitted by the light emitting element 401 is not glaring after a plurality of reflections and refraction, the user's eyes are better protected.

Further, the lighting component 40 further includes a circular circuit board 403. The light emitting element 401 is located on the circuit board 403, and the circuit board 403 is connected to the sound box 102. In some embodiments, the circuit board 403 contacts a surface of the sound box 102.

Specifically, the circuit board 403 is connected to the outer wall of the sound box 102.

The audio component 10, the housing 20, the lamp cover 30 and the light guide lens 402 are coaxially disposed.

When the lighting device with built-in speaker provided in some embodiments is installed, the speaker 101 is connected to the opening of the sound chamber 103 inside the sound box 102. The speaker 101 and the sound box 102 constitute the audio component 10. The speaker 101 is disposed toward one end of the housing 20 in the vertical direction. There is a sound transmission space between the speaker 101 and the housing 20. A plurality of passive diaphragms 104 are evenly spaced around the side of the sound box 102.

The circuit board 403 is connected to the outer wall of the sound box 102. The light emitting element 401 is disposed on the circuit board 403. The light emitting element 401 is disposed on the annular circuit board 403 and the light guide lens 402 is disposed on the light emitting element 401. The width of the light emitting element 401 is smaller than the thickness of the light guide lens 402.

The lamp cover 30 is connected to the outer side of the opening of the housing 20. The lamp cover 30 and the housing 20 together encompass a closed chamber, so that both the audio component 10 and the lighting component 40 are located in the chamber. The lighting component 40 is located between the audio component 10 and the inner wall of the chamber.

When the lighting device with built-in speaker provided in some embodiments operates, the sound emitted by the speaker 101 is transmitted out of the housing 20 through the sound transmission space between the speaker 101 and the housing 20. The sound chamber 103 inside the sound box 102 absorbs vibrations generated when the speaker 101 operates, which reduces damages to electronic devices and structural devices caused by vibrations, and ensures the normal operation of electronic devices and structural devices.

The lighting component 40 is located between the audio component 10 and the inner wall of the chamber. The chamber is enclosed by the lamp cover 30 and the housing 20 and the chamber is closed. The sound chamber 103 inside the sound box 102 absorbs vibrations generated when the speaker 101 operates. The lighting component 40 is located between the audio component 10 and the inner wall of the chamber. Thus the vibration generated when the speaker 101 operates does not affect the lighting component 40, and ensure that the lighting component 40 is not easily damaged or invalid.

Lights emitted by the light emitting element 401 are all propagated in the light guide lens 402, so that the overall space occupation of the lighting component 40 is relatively small, and is suitable for a lighting device with built-in speaker whose spatial structure is small or weight is light, thereby reducing the overall volume of the lighting device with built-in speaker. The light guide lens 402 is a ring column, and lights emitted from the light emitting element 401 uniformly emit lights 360 degrees around the lamp cover 30. The brightness of the lighting component 40 is ensured to be the same from any degree. Because lights emitted by the light emitting element 401 are not glare after a plurality of reflections and refractions, the user's eyes are better protected.

The lighting device with built-in speaker provided in some embodiments can independently use a speaker function and a lighting function by disposing an audio component and a lighting component. The speaker function and the lighting function do not affect each other. The speaker function and the lighting function can also be used simultaneously. The audio component and the lighting component are located in a closed chamber enclosed by a lamp cover and a housing. The sound emitted by a speaker is transmitted out of the housing through a sound transmission space between the speaker and the housing. The sound chamber inside the sound box absorbs vibrations generated when the speaker operates to reduce damages to electronic devices and structural devices caused by vibrations, ensure the normal operations of electronic devices and structural devices, and ensures that the optical instrument, the electronic device and the structural device in the speaker box are not easily damaged or invalid. The overall space occupation of the lighting component is relatively small, and it is suitable for a lighting device with built-in speaker whose spatial structure is small or weight is light, thereby reducing the overall volume of the lighting device with built-in speaker. The brightness of the lighting component 40 is the same at any degree. Because the light emitted by the light emitting element 401 is not glare after a plurality of reflections and refractions, the user's eyes are better protected.
