[0002] According to statistics, approximately 10%-49% of people worldwide suffer from varying degrees of insomnia. Among these, a staggering 38.2% of adults experience insomnia to varying degrees. Improving sleep has become a crucial topic in the health field, spawning a wide range of sleep-aid products, including sleep-aid speakers. These speakers play natural sounds like rain and waves, or specially crafted sleep-inducing music, from built-in or external sources. These products, while relaxing, mask ambient noise, improving sleep quality, and are popular with some insomniacs.

[0032] The present invention will be further described below with reference to specific embodiments and accompanying drawings.

[0033] Example 1:

[0034] Combine Figure 1-7As shown, the present invention is a sleep-aiding method for achieving a sense of being in the presence of the user by adjusting the direction of sound waves. The sleep-aiding speaker automatically / intelligently controls the angles of the speaker and the waveguide, and the waveguide reflects the sound waves emitted by the speaker to adjust the propagation direction of the sound waves, thereby achieving directional sound emission. The sound generated emits a strong sound pressure in a certain direction, and with the help of secondary reflection from the ceiling, walls or floor of the room, part of the sound perceived by the user can be made to come from the three-dimensional space outside the sleep-aiding speaker. That is, the sound subjectively perceived by the user does not come from the sleep-aiding speaker but from the top or side of the room, thereby creating a more natural and relaxing atmosphere and achieving the purpose of feeling as if one is in the presence of the user. For example, the sound of rain can be adjusted by automatically / intelligently adjusting the angle of the waveguide tube 3 to adjust the direction of the sound waves, so that the sound waves emitted by the speaker will be reflected to the ceiling of the room after encountering the tube wall of the waveguide tube 3, and then reflected to the human ear through the ceiling of the room, so that the sound of rain felt by the user can come from above (that is, the ceiling of the room) instead of from the sleep-aid speaker, making the sound source closer to nature and more realistic, achieving the purpose of being on the scene, allowing users to be more relaxed and happy, which is conducive to improving the sleep-aid effect.

[0035] See Figure 1 As shown in the figure, the specific control principle diagram of the sleep aid method of the present invention by adjusting the direction of sound waves to achieve the feeling of being in the scene, EQ scene and command configuration: preset mode and configuration mode through APP, specifically, it has at least the following two modes:

[0036] Method 1: The user speaks the command word to switch the corresponding angle adjustment through voice. After receiving this voice, the AI voice control module in the sleep aid speaker parses it into the corresponding angle adjustment instruction through the command parsing module to complete the angle adjustment setting; the sleep aid speaker receives the original audio stream and automatically / intelligently adjusts the angle of the waveguide to adjust the direction of the sound wave to produce the expected sound effect.

[0037] Method 2: The user chooses to adjust the angle through the APP, and the APP sends the corresponding angle adjustment command to the sleep aid speaker to complete the angle adjustment setting; the sleep aid speaker receives the original audio stream and automatically / intelligently adjusts the angle of the waveguide to adjust the direction of the sound waves to produce the expected sound effect.

[0038] See Figure 2-8 As shown, a sleep-aiding speaker is characterized in that it includes: a speaker body 1, an automatic angle adjustment device 2, a waveguide 3 and a speaker 4.

[0039] Among them, a main control board 11 is provided in the speaker body 1; the automatic angle adjustment device 2 includes an angle adjustment seat 21 rotatably mounted on the speaker body 1 and a motor assembly 22 for driving the angle adjustment seat 21 to rotate relative to the speaker body 1; the waveguide tube 3 is arranged at the front end of the angle adjustment seat 21 and protrudes outside the front end of the speaker body 1; the speaker 4 is installed at the front end of the angle adjustment seat 21 and is located on the rear side of the waveguide tube 3, and the normal of the central axis of the speaker forms an angle a with the tube wall of the waveguide tube 3, wherein 0°<a<180°, so that the sound waves emitted by the speaker will be reflected after encountering the tube wall of the waveguide tube 3; the motor assembly 22 and the speaker 4 are both electrically connected to the main control board 11, and the main control board 11 controls the operation of the motor assembly 22 to adjust the angle of the angle adjustment seat 21 and the waveguide tube 3. When the present invention is working, the main control board 11 controls the sound waves emitted by the speaker 4. Since the angle a formed by the normal of the central axis of the speaker and the wall of the waveguide tube 3 is greater than 0° and less than 180°, the sound waves emitted by the speaker will be reflected after encountering the wall of the waveguide tube 3. The user can adjust the propagation direction of the sound waves after the reflection by automatically / intelligently adjusting the angle adjustment seat 21 and the waveguide tube 3 relative to the speaker body 1 through the main control board in conjunction with the motor assembly 22, that is, adjust the propagation direction of the sound waves, thereby achieving directional sound emission, so that the formed sound emits a strong sound pressure in a certain direction, and then with the help of secondary reflection from the ceiling, wall or floor of the room, part of the sound perceived by the user can come from the three-dimensional space outside the speaker body, that is, the sound subjectively perceived by the user does not come from the speaker but from the top or side of the room, creating a more natural and relaxing atmosphere, making the sound field wider and more natural, and making the reproduced sound effect closer to and more realistic than the played sound source, thereby achieving the purpose of being on the scene, making the user more relaxed and happy, and improving the sleep-aiding effect. For example, for the sound of rain, the angle of the waveguide tube 3 can be automatically / intelligently adjusted through the angle automatic adjustment device 2, so that the sound waves emitted by the speaker will be reflected to the ceiling of the room after encountering the tube wall of the waveguide tube 3, and then reflected to the human ear through the ceiling of the room, so that the sound of rain felt by the user can come from above (i.e. the ceiling of the room) instead of from the main body of the speaker, making the sound source closer to nature and more realistic, allowing the user to feel more relaxed and happy, which is conducive to improving the sleep-aiding effect; for the sound of ocean waves, the angle of the waveguide tube 3 can be automatically / intelligently adjusted through the angle automatic adjustment device 2, so that the sound waves emitted by the speaker will be reflected to the floor after encountering the tube wall of the waveguide tube 3, and then reflected to the human ear through the floor, so that the sound of ocean waves felt by the user can come from below (i.e. the floor) instead of from the main body of the speaker, making the sound source closer to nature and more realistic, allowing the user to feel more relaxed and happy, which is conducive to improving the sleep-aiding effect.

[0040] When the angle adjustment base 21 and the waveguide tube 3 are automatically / intelligently adjusted relative to the speaker body 1 by the motor assembly 22, the direction and rotation angle of the motor assembly 22 are controlled by the main control board 11, which is a conventional technical means of motor control. More specifically, the main control board 11 can set a first music (such as rain sound), and then control the motor assembly 22 to drive the angle adjustment base 21 and the waveguide tube 3 to rotate upward (i.e., counterclockwise), so that the sound waves emitted by the speaker will later reflect from the wall of the waveguide tube 3 to the room ceiling, and then reflect from the room ceiling to the human ear. Alternatively, the main control board 11 can set a second music (such as ocean sound), and then control the motor assembly 22 to drive the angle adjustment base 21 and the waveguide tube 3 to rotate downward (i.e., clockwise), so that the sound waves emitted by the speaker will later reflect from the wall of the waveguide tube 3 to the room floor, and then reflect from the room floor to the human ear, thereby achieving the purpose of automatically / intelligently adjusting the angle adjustment base 21 and the waveguide tube 3 relative to the speaker body 1.

[0041] In some embodiments, a more intelligent approach is to collect musical sounds through a pickup connected to the main control board 11 and compare them with the sound types stored in the main control board 11. If the sound types match, the motor assembly 22 is controlled to drive the angle adjustment base 21 and waveguide 3 to rotate clockwise or counterclockwise, thereby achieving the purpose of intelligent adjustment. For example, the sound waves emitted by the speaker are rain sounds and are collected by the pickup. The main control board 11 compares them with the stored rain sounds. If they match, the motor assembly 22 is controlled to drive the angle adjustment base 21 and waveguide 3 to rotate upward (i.e., counterclockwise). The sound waves emitted by the speaker will then hit the wall of the waveguide 3 and be reflected to the ceiling of the room, and then reflected from the ceiling to the human ear.

[0042] The normal line of the central axis of the loudspeaker forms an angle a with the wall of the waveguide tube 3 , wherein the optimal angle is: 15°<a<35°. In this embodiment, a is 23°.

[0043] The speaker body 1 also includes:

[0044] A speaker 13 is mounted at the front end of the housing 12. A protective screen 14 is provided at the front end of the housing 12, and the protective screen 14 covers the front end of the speaker 13. The speaker 13 is electrically connected to the main control board 11. The speaker 13 can be a full-range speaker or a subwoofer. In some embodiments, the speaker 13 may not be provided.

[0045] The main control board 11 is equipped with a wireless communication module 111 and a memory card connector 112. The memory card connector 112 is equipped with a memory card. The memory card is mainly used to store music and white noise, such as rain, ocean waves, streams, mountain streams, burning wood, etc. The white noise includes but is not limited to the sound of rain, waves, streams, mountain streams, burning wood, etc. The wireless communication module 111 is one or more of a Bluetooth module, a WiFi module, or a 4G communication module. Users can use a mobile phone or other terminal to achieve wireless communication with the wireless communication module 151 to control the operation of the entire sleep aid speaker, which is extremely convenient to use.

[0046] A notch 31 is formed at the upper end of the waveguide 3 , and the notch 31 extends to the front and rear ends of the waveguide 3 , so that the waveguide 3 is in an inverted C shape or a semicircle, which can better reflect sound waves / sound.

[0047] The size of the waveguide tube 3 gradually increases along its rear end and forward, and it has an excellent sound wave / voice reflection effect.

[0048] Among them, when the waveguide 3 is in a horizontal state, the sound pressure emitted by the speaker 4 is the strongest, and the sounds at other angles are relatively weak.

[0049] The motor assembly 22 includes a motor 221 and a transmission mechanism 222 connected to the rotating shaft of the motor 221. A linkage part 211 is provided on the outside of the angle adjustment seat 21. The linkage part 211 is connected to the transmission mechanism 222. The transmission mechanism 222 pulls the linkage part 211 to move to drive the angle adjustment seat 21 to rotate.

[0050] The transmission mechanism 222 includes a crank 202 mounted on the rotating shaft 201 of the motor 221, and a connecting rod 203 rotatably mounted at the end of the crank 202. The end of the connecting rod 203 is rotatably connected to the end of the linkage portion 211. When the automatic angle adjustment device 2 is in operation, the motor 221 drives the rotating shaft 201 to rotate. The rotating shaft 201, through the crank 202 and the connecting rod 203, drives the linkage portion 211 to rotate, thereby driving the angle adjustment base 21 to rotate.

[0051] The speaker body 1 is provided with a mounting slot 10 for mounting the angle adjustment seat 21. The angle adjustment seat 21 is hingedly mounted on both sides of the mounting slot 10 via hinges 20, wherein the hinges 20 serve as the axis of rotation for the angle adjustment seat 21. Furthermore, the inner wall of the mounting slot 10 is provided with an arc-shaped travel slide hole 101. The linkage portion 211 is inserted into and slides within the arc-shaped travel slide hole 101. The linkage portion 211 can slide along the arc-shaped travel slide hole 101 to facilitate the rotation of the angle adjustment seat 21. The arc-shaped travel slide hole 101 can also limit the linkage portion 211 to prevent the linkage portion 211 from deflecting. At the same time, the arc-shaped travel slide hole 101 can also limit the sliding range of the linkage portion 211, thereby limiting the rotational travel of the angle adjustment seat 21.

[0052] The speaker body 1 includes a box body 12, which is provided with a detachable U-shaped top plate 121. The upper end of the U-shaped top plate 121 is provided with the mounting groove 10, and the lower end of the U-shaped top plate 121 is provided with a plurality of positioning columns 102 and screw hole columns 103 located beside the positioning columns 102. The end of the positioning column 102 protrudes from the end of the screw hole column 103. The motor 221 is provided with a lug 204, which is provided with a positioning hole 205 and a hole position 206 located beside the positioning hole 205. The lug 204 is sleeved on and positioned on the positioning column 102 through the positioning hole 205 to reach the end of the pre-positioning, and the hole position 206 corresponds to the screw hole column 103. After the screw passes through the hole position 206, it is screwed fixed with the screw hole column 103 to fix the motor 221 to the bottom of the U-shaped top plate 121. Its assembly structure is simple and easy to install.

[0053] The bottom of the U-shaped top plate 121 is also provided with an air-avoiding positioning groove 104, and the motor 221 is partially embedded in the air-avoiding positioning groove 104, which can make the entire box body smaller and the overall volume of the present invention smaller. The air-avoiding positioning groove 104 can also position the motor 221, ensuring that the motor 221 is more stably installed at the bottom of the U-shaped top plate 121.

[0054] The other end of the crank 202 connected to the connecting rod 203 is provided with a through hole 207, and the crank 202 is provided with a first socket 208 penetrating the through hole 207 along its upper end downward. The rotating shaft 201 of the motor 221 is provided with a second socket 209 adapted to the first socket 208. After the rotating shaft 201 is installed in the through hole 207, the first socket 208 and the second socket 209, and the pin 200 are inserted into the first socket 208 and the second socket 209 to fix the crank 202 to the rotating shaft 201. The assembly structure is simple and the installation is convenient. Screws can also be used instead of the pin 200 to be screwed fixed in the first socket 208 and the second socket 209 to achieve the same purpose of fixed assembly.

[0055] To sum up, the present invention uses the sleep-aid speaker to automatically / intelligently control the angles of the speaker and the waveguide, and the waveguide reflects the sound waves emitted by the speaker to adjust the propagation direction of the sound waves, realize directional sound emission, and make the formed sound emit strong sound pressure in a certain direction. Then, with the help of secondary reflection from the ceiling, wall or floor of the room, part of the sound felt by the user can come from the three-dimensional space outside the sleep-aid speaker, that is, the sound subjectively felt by the user does not come from the sleep-aid speaker but from the top or side of the room, creating a more natural and relaxing atmosphere, achieving the purpose of being on the scene and feeling, thereby improving the sleep-aid effect.

[0056] Example 2:

[0057] Combine Figure 7-13 As shown, the present invention provides a sleep-aiding method for achieving a sense of being in the presence of the user by adjusting the direction of sound waves. The sleep-aiding method manually adjusts the angles of the speaker and the waveguide in the sleep-aiding speaker box, and then the waveguide reflects the sound waves emitted by the speaker to adjust the propagation direction of the sound waves, thereby achieving directional sound emission. The generated sound emits a strong sound pressure in a certain direction, and then with the help of secondary reflection from the ceiling, walls or floor of the room, part of the sound felt by the user can come from the three-dimensional space outside the sleep-aiding speaker box. That is, the sound subjectively felt by the user does not come from the sleep-aiding speaker box but from the top or side of the room, creating a more natural and relaxing atmosphere, thereby achieving the purpose of feeling as if one is in the presence of the user.

[0058] That is to say, the second embodiment manually adjusts the angles of the loudspeaker and the waveguide, which is different from the first embodiment which automatically adjusts the angles of the loudspeaker and the waveguide.

[0059] Specifically, the specific structures of sleep aid speakers are different, the differences are as follows:

[0060] The sleep-aiding speaker box includes: a speaker box body 1 , an angle adjustment seat 21 , a waveguide 3 , and a speaker 4 .

[0061] Among them, the angle adjustment seat 21 is installed on the speaker body 1 in an adjustable angle manner; the waveguide tube 3 is arranged at the front end of the angle adjustment seat 21 and protrudes outside the front end of the speaker body 1; the speaker 4 is installed at the front end of the angle adjustment seat 21 and is located on the rear side of the waveguide tube 3, and the normal of the central axis of the speaker forms an angle a with the tube wall of the waveguide tube 3, wherein 0°<a<180°, so that the sound waves emitted by the speaker will be reflected after encountering the tube wall of the waveguide tube 3. When the present invention is working, the sound waves emitted by the speaker 4 will be reflected after encountering the wall of the waveguide tube 3 because the angle a formed by the normal of the speaker's central axis and the tube wall of the waveguide tube 3 is greater than 0° and less than 180°. The user can adjust the propagation direction of the sound waves after reflection by manually adjusting the angle of the angle adjustment seat 21 relative to the speaker body 1, thereby realizing directional sound emission, so that the formed sound emits a strong sound pressure in a certain direction, and then with the help of secondary reflection from the ceiling, wall or floor of the room, part of the sound felt by the user can come from the three-dimensional space outside the speaker body, that is, the sound subjectively felt by the user is not from the speaker but from the top or side of the room, creating a more natural and relaxing atmosphere, making the sound field wider and more natural, and making the reproduced sound effect closer and more realistic to the played sound source, so that the user is more relaxed and happy, and improving the sleep-aiding effect. For example, for the sound of rain, the angle of the waveguide tube 3 can be adjusted by adjusting the angle of the angle adjustment seat 21, so that the sound waves emitted by the speaker will be reflected to the ceiling of the room after encountering the tube wall of the waveguide tube 3, and then reflected to the human ear through the ceiling of the room, so that the sound of rain felt by the user can come from above (i.e. the ceiling of the room) instead of from the main body of the speaker, making the sound source closer to nature and more realistic, allowing the user to feel more relaxed and happy, which is conducive to improving the sleep-aiding effect; for the sound of ocean waves, the angle of the waveguide tube 3 can be adjusted by adjusting the angle of the angle adjustment seat 21, so that the sound waves emitted by the speaker will be reflected to the floor after encountering the tube wall of the waveguide tube 3, and then reflected to the human ear through the floor, so that the sound of ocean waves felt by the user can come from below (i.e. the floor) instead of from the main body of the speaker, making the sound source closer to nature and more realistic, allowing the user to feel more relaxed and happy, which is conducive to improving the sleep-aiding effect.

[0062] The normal line of the central axis of the loudspeaker forms an angle a with the wall of the waveguide tube 3 , wherein the optimal angle is: 15°<a<35°. In this embodiment, a is 23°.

[0063] The speaker body 1 includes:

[0064] The angle adjustment seat 21 is installed on the upper end of the box body 12;

[0065] The speaker 13 is mounted at the front end of the housing 12. A protective screen 14 is provided at the front end of the housing 12. The protective screen 14 covers the front end of the speaker 13 to protect the speaker 13. The speaker 13 may be a full-range speaker or a subwoofer. In some embodiments, the speaker 13 may not be provided.

[0066] The main control board 15 is installed in the box 12. The main control board 15 is provided with a wireless communication module 151 and a memory card connector 152.

[0068] A notch 31 is formed at the upper end of the waveguide 3 , and the notch 31 extends to the front and rear ends of the waveguide 3 , so that the waveguide 3 is in an inverted C shape or a semicircle, which can better reflect sound waves / sound.

[0069] The size of the waveguide tube 3 gradually increases along its rear end and forward, and it has an excellent sound wave / voice reflection effect.

[0070] Among them, when the waveguide 3 is in a horizontal state, the sound pressure emitted by the speaker 4 is the strongest, and the sounds at other angles are relatively weak.

[0071] An angle gear adjustment structure 5 is provided between the angle adjustment seat 21 and the speaker body 1. The angle between the angle adjustment seat 21 and the speaker body 1 is adjusted through the angle gear adjustment structure 5 and can be positioned after the angle adjustment, ensuring that the angle adjustment seat 21 is stably positioned on the speaker body 1 after the angle adjustment.

[0072] Specifically, the angle gear adjustment structure 5 includes a gear plate 51 and a positioning module 52 .

[0073] The shift plate 51 is fixed to the outside of the angle adjustment seat 21, and a plurality of shift slots 511 are provided on the outer side of the shift plate 51;

[0074] The positioning module 52 includes a positioning block 521 that is installed in the speaker body 1 and is movable, and a spring 522 is arranged between the positioning block 521 and the positioning block 521. The positioning block 521 protrudes outward under the elastic force of the spring and is stuck in one of the gear slots 511, so that positioning can be achieved. When it is necessary to adjust the angle of the angle adjustment seat 21 relative to the speaker body 1, the angle adjustment seat 21 is directly rotated to force the positioning block 521 to leave the previous gear slot 511, and compress the spring to retract until the positioning block 521 enters the next gear slot 511. The positioning block 521 protrudes outward under the elastic force of the spring and is stuck in the next gear slot 511, thereby achieving the purpose of gear adjustment, and realizing that the angle adjustment seat 21 and the speaker body 1 can be positioned after the angle is adjusted by the angle gear adjustment structure 5, ensuring that the angle adjustment seat 21 is stably positioned on the speaker body 1 after the angle adjustment.

[0075] A first positioning hole 512 is provided on the shift plate 51, and a first positioning column 2111 is formed on the outer side of the angle adjustment seat 21. The first positioning column 2111 is embedded in the first positioning column 2111 to form positioning, thereby achieving the purpose of pre-positioning, and is screwed through the through-hole of the shift plate 51 and then screwed to the screw hole on the outer side of the angle adjustment seat 21. Its assembly structure is simpler and the assembly efficiency is higher.

[0076] The speaker body 1 is provided with a mounting groove 10 for the angle adjustment seat 21 to be installed. Specifically, the mounting groove 10 is provided on the box body 12. The two sides of the angle adjustment seat 21 are hingedly mounted to the inner walls of the mounting groove 10 via hinges 20 respectively. This is a conventional design of a rotating structure and will not be described in detail here. The positioning module 52 is provided on the inner wall of the positioning module 52; the gear slot 511 is an arc slot, and an arc-shaped protrusion 513 is formed between two adjacent gear slots 511, which enables the positioning block 521 to slide more smoothly to the next gear slot 511 after leaving the previous gear slot 511; the front end of the positioning block 521 is spherical, which enables the positioning block 521 to slide more smoothly to the next gear slot 511 after leaving the previous gear slot 511.

[0077] The inner walls on both sides of the mounting groove 10 are formed with a first stroke limiting protrusion 111 and a second stroke limiting protrusion 112. The shift plate 51 is placed between the first stroke limiting protrusion 111 and the second stroke limiting protrusion 112, and can rotate at intervals between the first stroke limiting protrusion 111 and the second stroke limiting protrusion 112. It can limit the rotation angle of the angle adjustment seat 21 to prevent the positioning block 521 from being unable to enter the next gear slot 511 after leaving the previous gear slot 511 after the angle adjustment seat 21 rotates, resulting in the angle adjustment seat 21 being unable to be positioned, that is, ensuring that the positioning block 521 can always be stuck in a gear slot 511 to ensure product quality.

[0078] The inner wall of the installation groove 10 is provided with a receiving groove 113, and the spring 522 and the positioning block 521 are installed in the receiving groove 113 in sequence. The rear side of the positioning block 521 is provided with a convex edge 501 protruding from the inside to the outside, and the opening of the receiving groove 113 is provided with a convex portion 114 protruding from the outside to the inside and used to block the convex edge 501, so that only the front end of the positioning block 521 protrudes outside the receiving groove 113, ensuring that the positioning block 521 will not be separated from the receiving groove 113 as a whole, so that the angle gear adjustment structure 5 is always in an effective state.

[0079] To sum up, when the present invention is working, the sound waves emitted by the speaker 4 will be reflected after encountering the wall of the waveguide tube 3 because the angle a formed by the normal of the speaker's central axis and the tube wall of the waveguide tube 3 is greater than 0° and less than 180°. The user can adjust the propagation direction of the sound waves after reflection by manually adjusting the angle of the angle adjustment seat 21 relative to the speaker body 1, thereby realizing directional sound emission, so that the formed sound emits a strong sound pressure in a certain direction, and then with the help of secondary reflection from the ceiling, wall or floor of the room, part of the sound felt by the user can come from the three-dimensional space outside the speaker body, that is, the sound subjectively felt by the user is not from the speaker but from the top or side of the room, creating a more natural and relaxing atmosphere, making the sound field wider and more natural, and making the reproduced sound effect closer and more realistic to the played sound source, so that the user is more relaxed and happy, and improving the sleep-aiding effect.
