Description

Technical fields:

[0001] This utility model relates to the field of speaker product technology, and specifically to an intelligent sleep aid speaker. Background technology:

[0002] With the ever-accelerating pace of life, more and more people are suffering from sleep disorders. A World Health Organization report shows that approximately 10%-49% of the global population suffers from insomnia to varying degrees. Among them, a staggering 38.2% of adults experience insomnia to varying degrees. Improving sleep has become a crucial topic in the health field, leading to the development of many different types of sleep aids, one of which is the sleep aid speaker. This speaker plays natural sounds such as rain or ocean waves, or specially crafted sleep-inducing music, either from built-in or external sources. It helps users relax both physically and mentally, and can also mask some environmental noise, thereby improving sleep quality and gaining popularity among insomnia sufferers.

[0003] Chinese utility model patent ZL202123326682.X discloses a sleep aid speaker, which includes a main body with a main control circuit board inside. The main body has a volume control switch connected to the main control circuit board, and a charging platform. A wireless charging module is installed inside the main body and connected to the main control circuit board. The wireless charging module is used to charge electronic devices placed on the charging platform. The volume control switch allows selection of different sound sources to suit different user needs. Furthermore, the sleep aid speaker includes a charging platform, allowing users to charge electronic devices while relaxing, falling asleep, or when their devices are out of power, saving space compared to a single wireless charging device and making it easier to store. The sleep aid speaker is also more conspicuous and easier to find than a single wireless charging device, saving users time searching for charging devices. This multi-functional, practical, and convenient device brings convenience to users' lives.

[0004] However, the sound-emitting design of the sleep aid speaker disclosed in the above patent is basically the same as that of ordinary speakers. Both use a horn / loudspeaker to emit sound directly, so that the sound perceived by the user comes from the speaker itself. The sound field is narrow and there is no three-dimensional effect. Although natural sounds such as rain, waves, and leaves are played, due to the above limitations, the user's overall experience is still not natural enough and there is no feeling of being there. Therefore, the overall effect is limited and affects the sleep aid effect.

[0005] In view of the above, the inventors propose the following technical solution. Utility Model Content:

[0006] The purpose of this invention is to overcome the shortcomings of the existing technology and provide an intelligent sleep aid speaker.

[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: The intelligent sleep aid speaker includes: a speaker body, in which a main control board is disposed; an automatic angle adjustment device, which includes an angle adjustment seat rotatably mounted on the speaker body and a motor assembly for driving the angle adjustment seat to rotate relative to the speaker body; a waveguide, which is disposed at the front end of the angle adjustment seat and protrudes from the front end of the speaker body; a speaker, which is mounted at the front end of the angle adjustment seat and located behind the waveguide, and the central axis normal of the speaker forms an angle α with the wall of the waveguide, wherein 0° < α < 180°, so that the sound waves emitted by the speaker will be reflected after encountering the wall of the waveguide; the motor assembly and the speaker are both electrically connected to the main control board, and the main control board controls the operation of the motor assembly to adjust the angle of the angle adjustment seat and the waveguide.

[0008] Furthermore, in the above technical solution, the upper end of the waveguide has a cut, and the cut extends to both ends of the waveguide, making the waveguide appear as an inverted C-shape or a semi-circle.

[0009] Furthermore, in the above technical solution, the size of the waveguide gradually increases from its rear end forward.

[0010] Furthermore, in the above technical solution, the motor assembly includes a motor and a transmission mechanism connected to the motor's shaft. A linkage part is provided on the outside of the angle adjustment seat, and the linkage part is connected to the transmission mechanism.

[0011] Furthermore, in the above technical solution, the transmission mechanism includes a crank mounted on the motor shaft and a connecting rod rotatably mounted on the end of the crank, the end of the connecting rod being rotatably connected to the end of the linkage part.

[0012] Furthermore, in the above technical solution, the speaker body is provided with a mounting groove for mounting the angle adjustment seat. The two sides of the angle adjustment seat are respectively hinged to the inner walls of the two sides of the mounting groove through hinges. The inner wall of the mounting groove is also provided with an arc-shaped travel sliding hole. The linkage part passes through the arc-shaped travel sliding hole and can slide in the arc-shaped travel sliding hole.

[0013] Furthermore, in the above technical solution, the speaker body includes a cabinet with a detachable U-shaped top plate. The upper end of the U-shaped top plate has the aforementioned mounting groove, and the lower end of the U-shaped top plate has several positioning posts and screw hole posts located next to the positioning posts. The end of the positioning post protrudes beyond the end of the screw hole post. The motor has a lug with a positioning hole and a hole located next to the positioning hole. The lug is fitted onto and positioned on the positioning post through the positioning hole, and the hole corresponds to the screw hole post. After the screw passes through the hole, it is screwed and fixed to the screw hole post to fix the motor to the bottom of the U-shaped top plate.

[0014] Furthermore, in the above technical solution, the bottom of the U-shaped top plate is also provided with a clearance positioning groove, and the motor is partially embedded in the clearance positioning groove.

[0015] Furthermore, in the above technical solution, the other end of the crank connecting to the connecting rod is provided with a through hole, and the crank is provided with a first insertion hole through the through hole along its upper end downward. The motor shaft is provided with a second insertion hole that matches the first insertion hole. After the shaft is installed in the through hole, the first insertion hole and the second insertion hole are connected by a pin, so as to fix the crank and the shaft together.

[0016] Furthermore, in the above technical solution, the speaker body also includes: a speaker, which is installed at the front end of the enclosure, and the front end of the enclosure is also provided with a protective net, which covers the front end of the speaker; the speaker is electrically connected to the main control board; the main control board is provided with a wireless communication module and a memory card connector, and the memory card connector is equipped with a memory card; the wireless communication module is one or two of Bluetooth module, WiFi module, or 4G communication module.

[0017] After adopting the above technical solution, this utility model has the following beneficial effects compared with the prior art: In specific operation, the main control board controls the sound waves emitted by the speaker. Since the angle α formed by the central axis normal of the speaker and the wall of the waveguide 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. The user can adjust the direction of sound wave propagation after reflection by automatically / intelligently adjusting the angle adjustment seat and the angle of the waveguide relative to the speaker body through the main control board and motor assembly, thereby achieving directional sound generation. The resulting sound emits a strong sound pressure in a certain direction. With the help of secondary reflection from the ceiling, walls or floor of the room, part of the sound perceived by the user can come from the three-dimensional space outside the speaker body. This makes the sound perceived by the user 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, making the reproduced sound effect closer and more realistic to the played sound source, making the user more relaxed and happy, and improving the sleep aid effect.

[0025] The present invention will be further described below with reference to specific embodiments and accompanying drawings.

[0026] See Figure 1-7 As shown, this is an intelligent sleep aid speaker, characterized in that it includes: a speaker body 1, an automatic angle adjustment device 2, a waveguide 3, and a speaker 4.

[0027] The speaker body 1 contains a main control board 11; 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 3 is located at the front end of the angle adjustment seat 21 and protrudes from the front end of the speaker body 1; the speaker 4 is mounted at the front end of the angle adjustment seat 21 and located behind the waveguide 3, and the central axis normal of the speaker forms an angle α with the wall of the waveguide 3, wherein 0° < α < 180°, so that the sound waves emitted by the speaker will be reflected after encountering the wall of the waveguide 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 3. In practical operation, the main control board 11 controls the sound waves emitted by the speaker 4. Since the angle α formed between the central axis normal of the speaker and the wall of the waveguide 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 3. The user can adjust the direction of sound wave propagation after reflection by automatically / intelligently adjusting the angle adjustment seat 21 and the angle of the waveguide 3 relative to the speaker body 1 through the main control board and the motor assembly 22, thereby achieving directional sound generation. The resulting sound emits a strong sound pressure in a certain direction. With the help of secondary reflection from the ceiling, walls or floor of the room, part of the sound perceived by the user can come from the three-dimensional space outside the speaker body. This makes the sound perceived by the user 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, making the reproduced sound effect closer to and more realistic than the played sound source, making the user more relaxed and happy, and improving the sleep aid effect. For example, the sound of rain can be automatically / intelligently adjusted by the angle adjustment device 2 to adjust the angle of the waveguide 3. This causes the sound waves emitted by the speaker to be reflected off the wall of the waveguide 3 and then off to the ceiling, and finally off to the user's ear. This makes the sound of rain perceived by the user come from above (i.e., the ceiling) rather than from the speaker itself, making the sound source more natural and realistic, allowing the user to relax and enjoy themselves, and thus improving the sleep-inducing effect. Similarly, the sound of ocean waves can be automatically / intelligently adjusted by the angle adjustment device 2 to adjust the angle of the waveguide 3. This causes the sound waves emitted by the speaker to be reflected off the wall of the waveguide 3 and then off to the floor, and finally off to the user's ear. This makes the sound of ocean waves perceived by the user come from below (i.e., the floor) rather than from the speaker itself, making the sound source more natural and realistic, allowing the user to relax and enjoy themselves, and thus improving the sleep-inducing effect.

[0028] When the angle adjustment seat 21 and waveguide 3 are automatically / intelligently adjusted relative to the speaker body 1 by the motor assembly 22, the main control board 11 controls the direction and rotation angle of the motor assembly 22, which is a conventional motor control technique. More specifically, the main control board 11 can set a first music (such as rain), which will control the motor assembly 22 to drive the angle adjustment seat 21 and waveguide 3 to rotate upward (i.e., counterclockwise), so that the sound waves emitted by the speaker will be reflected by the wall of the waveguide 3 to the ceiling and then to the listener's ear. Alternatively, the main control board 11 can set a second music (such as ocean waves), which will control the motor assembly 22 to drive the angle adjustment seat 21 and waveguide 3 to rotate downward (i.e., clockwise), so that the sound waves emitted by the speaker will be reflected by the wall of the waveguide 3 to the floor and then to the listener's ear, thus achieving the purpose of automatically / intelligently adjusting the angle adjustment seat 21 and waveguide 3 relative to the speaker body 1.

[0029] In some embodiments, a more intelligent approach is to collect music sounds via a microphone connected to the main control board 11 and compare them with the sound types stored in the main control board 11. If they match, the motor assembly 22 is controlled to drive the angle adjustment seat 21 and the waveguide 3 to rotate clockwise or counterclockwise, achieving intelligent adjustment. For example, if the sound wave emitted by the speaker is the sound of rain and is collected by the microphone, the main control board 11 compares it with the stored rain sounds. If they match, the motor assembly 22 is controlled to drive the angle adjustment seat 21 and the waveguide 3 to rotate upward (i.e., counterclockwise), so that the sound waves emitted by the speaker will be reflected to the ceiling of the room after encountering the wall of the waveguide 3, and then reflected to the ear by the ceiling.

[0030] The central axis normal of the loudspeaker forms an angle α with the wall of the waveguide 3. The optimal angle is 15° < α < 35°. In this embodiment, α is 23°.

[0031] The speaker body 1 also includes:

[0032] A speaker 13 is mounted on the front end of a housing 12, and a protective mesh 14 is also provided on the front end of the housing 12, which covers the front end of the speaker 13; the speaker 13 is electrically connected to the main control board 11; wherein, the speaker 13 can be a full-range speaker or a subwoofer. In some embodiments, the speaker 13 may not be provided.

[0033] The main control board 11 is equipped with a wireless communication module 111 and a memory card connector 112. The memory card connector 112 holds a memory card, which is mainly used to store music and white noise, including but not limited to rain sounds, ocean waves, stream sounds, flowing water sounds, and wood burning sounds. The wireless communication module 111 is one or two of Bluetooth, WiFi, or 4G communication modules. Users can wirelessly communicate with the wireless communication module 111 via mobile phones or other terminals to control the entire sleep aid speaker, making it extremely convenient to use.

[0034] The upper end of the waveguide 3 has a cut 31, which extends to both ends of the waveguide 3, making the waveguide 3 into an inverted C-shape or semi-circle, which can better reflect sound waves / sound.

[0035] The waveguide 3 gradually increases in size from its rear end forward, and it has excellent sound wave / sound reflection effect.

[0036] Among them, the sound pressure emitted by the speaker 4 is strongest when the waveguide 3 is in a horizontal state, and the sound at other angles is relatively weak.

[0037] 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, thereby driving the angle adjustment seat 21 to rotate.

[0038] The transmission mechanism 222 includes a crank 202 mounted on the 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 211. When the automatic angle adjustment device 2 is working, the motor 221 drives the shaft 201 to rotate. The shaft 201, through the crank 202 and the connecting rod 203, drives the linkage 211 to rotate, thereby achieving the purpose of driving the angle adjustment seat 21 to rotate.

[0039] The speaker body 1 is provided with a mounting groove 10 for mounting the angle adjustment seat 21. The angle adjustment seat 21 is hinged to the inner walls of the mounting groove 10 on both sides by hinge members 20, wherein the hinge members 20 serve as the axis of rotation of the angle adjustment seat 21. The inner wall of the mounting groove 10 is also provided with an arc-shaped travel sliding hole 101. The linkage part 211 passes through the arc-shaped travel sliding hole 101 and can slide in the arc-shaped travel sliding hole 101. The linkage part 211 can slide along the arc-shaped travel sliding hole 101 to drive the angle adjustment seat 21 to rotate. The arc-shaped travel sliding hole 101 can also limit the linkage part 211 to prevent the linkage part 211 from deviating. At the same time, the arc-shaped travel sliding hole 101 can also limit the sliding range of the linkage part 211, thereby limiting the rotation stroke of the angle adjustment seat 21.

[0040] The speaker body 1 includes a cabinet 12, on which a detachable U-shaped top plate 121 is provided. 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 posts 102 and screw hole posts 103 located beside the positioning posts 102. The end of the positioning post 102 protrudes beyond the end of the screw hole post 103. The motor 221 is provided with a lug 204. The lug 204 is provided with a positioning hole 205 and a hole position 206 located beside the positioning hole 205. The lug 204 is fitted onto and positioned on the positioning post 102 through the positioning hole 205, reaching the pre-positioned end. The hole position 206 corresponds to the screw hole post 103. After the screw passes through the hole position 206, it is screwed and fixed to the screw hole post 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.

[0041] The bottom of the U-shaped top plate 121 is also provided with a clearance positioning groove 104. The motor 221 is partially embedded in the clearance positioning groove 104, which allows the entire box to be made smaller and the overall volume of the present invention to be smaller. In addition, the clearance 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.

[0042] The crank 202 is connected to the connecting rod 203 at one end, and a through hole 207 is provided at the other end. The crank 202 is also provided with a first insertion hole 208 through the through hole 207 at its upper end. The shaft 201 of the motor 221 is provided with a second insertion hole 209 that matches the first insertion hole 208. After the shaft 201 is inserted into the through hole 207, the first insertion hole 208 and the second insertion hole 209 are connected, and the pin 200 is inserted into the first insertion hole 208 and the second insertion hole 209 to fix the crank 202 and the shaft 201. The assembly structure is simple and easy to install. Alternatively, screws can be used instead of pins 200 to fix the crank 202 in the first insertion hole 208 and the second insertion hole 209, which also achieves the purpose of fixed assembly.

[0043] In summary, during operation, the main control board 11 controls the sound waves emitted by the speaker 4. Since the angle α formed between the central axis normal of the speaker and the wall of the waveguide 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 3. The user can adjust the direction of sound wave propagation after reflection by automatically / intelligently adjusting the angle adjustment seat 21 and the angle of the waveguide 3 relative to the speaker body 1 through the main control board and motor assembly 22, thereby achieving directional sound generation. This results in a strong sound pressure in a certain direction. With the help of secondary reflection from the ceiling, walls, or floor of the room, a portion of the sound perceived by the user can come from the three-dimensional space outside the speaker body. This makes the user's subjective perception of sound not coming 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 effects closer to and more realistic than the played sound source. This makes the user more relaxed and happy, and improves the sleep-aiding effect.
