Description

A sleep aid speaker Technical Field

[0001] This utility model relates to the technical field of speaker products, and specifically to a 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. Summary of the Invention

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

[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: The sleep aid speaker includes: a speaker body; an angle adjustment seat, which is installed on the speaker body in an adjustable manner; a waveguide, which is disposed at the front end of the angle adjustment seat and protrudes from the front end of the speaker body; and a speaker, which is installed at the front end of the angle adjustment seat and located on the rear side of 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.

[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, an angle adjustment structure is provided between the angle adjustment seat and the speaker body.

[0011] Furthermore, in the above technical solution, the angle adjustment structure includes: a position plate, which is fixed to the outside of the angle adjustment seat, and the outer side of the position plate is provided with multiple position slots; a positioning module, which includes a positioning block installed inside the speaker body and movable, and a spring disposed between the positioning blocks, the positioning block protruding outward under the elastic force of the spring and locking into one of the position slots.

[0012] Furthermore, in the above technical solution, the gear plate is provided with a positioning hole, and the outer side of the angle adjustment seat is formed with a positioning post. The positioning post is embedded in the positioning hole to form a positioning, and is screwed and fixed to the screw hole on the outer side of the angle adjustment seat by a screw passing through the through hole of the gear plate.

[0013] 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 mounting groove via hinges. The positioning module is disposed on the inner wall of the positioning module. The gear slot is an arc groove, and an arc protrusion is formed between two adjacent gear slots. The front end of the positioning block is spherical.

[0014] Furthermore, in the above technical solution, the inner walls on both sides of the mounting groove are formed with a first stroke limiting protrusion and a second stroke limiting protrusion, and the stop plate is placed between the first stroke limiting protrusion and the second stroke limiting protrusion, and can rotate at intervals between the first stroke limiting protrusion and the second stroke limiting protrusion.

[0015] Furthermore, in the above technical solution, the inner wall of the mounting groove is provided with a receiving groove, the spring and the positioning block are installed in the receiving groove in sequence, the rear side of the positioning block is provided with a protruding edge protruding from the inside to the outside, and the opening of the receiving groove is provided with a protruding part protruding from the outside to the inside to block the protruding edge, so that only the front end of the positioning block protrudes out of the receiving groove.

[0016] Furthermore, in the above technical solution, the speaker body includes: a cabinet; an angle adjustment seat installed on the upper end of the cabinet; a speaker installed on the front end of the cabinet, and a protective net is also provided on the front end of the cabinet, the protective net covering the front end of the speaker; a main control board installed inside the cabinet, the main control board having a wireless communication module and a memory card connector, the memory card connector having a memory card installed; the wireless communication module is one or two of Bluetooth, WiFi, or 4G communication modules; the speaker and the loudspeaker are both electrically connected to the main control board.

[0017] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art: In specific operation, the sound waves emitted by the speaker will be reflected after encountering the wall of the waveguide because 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 user can adjust the direction of sound wave propagation after reflection by adjusting the angle adjustment seat relative to the speaker body, thereby achieving directional sound generation. The sound generated will produce 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 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] As shown in Figures 1-7, this is a sleep aid speaker, which includes: speaker body 1, angle adjustment seat 2, waveguide 3, and speaker 4.

[0027] The angle adjustment seat 2 is mounted on the speaker body 1 with an adjustable angle; the waveguide 3 is located at the front end of the angle adjustment seat 2 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 2 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. In practical operation, the sound waves emitted by the speaker 4 are reflected when they encounter the wall of the waveguide 3 because the angle α formed between the speaker's central axis normal and the waveguide 3 is greater than 0° and less than 180°. The user can adjust the direction of sound wave propagation after reflection by adjusting the angle adjustment seat 2 relative to the speaker body 1, 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, some of the sound perceived by the user comes 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. The sound field is wider and more natural, making the reproduced sound effects closer to and more realistic than the source, allowing the user to relax and enjoy themselves, and improving the sleep-aiding effect. For example, the sound of rain can be adjusted by changing the angle of the angle adjustment seat 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, before reaching the user's ear. This makes the sound of rain perceived by the user feel as coming from above (the ceiling) rather than from the speaker itself, resulting in a more natural and realistic sound that promotes relaxation and improves sleep quality. Similarly, the sound of ocean waves can be adjusted by changing the angle of the angle adjustment seat 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, before reaching the user's ear. This makes the sound of ocean waves perceived by the user feel as coming from below (the floor) rather than from the speaker itself, resulting in a more natural and realistic sound that promotes relaxation and improves sleep quality.

[0028] 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°.

[0029] The speaker body 1 includes:

[0030] Box 12; the angle adjustment seat 2 is installed on the upper end of box 12;

[0031] 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. The protective mesh 14 covers the front end of the speaker 13 and serves to protect the speaker 13. The speaker 13 can be a full-range speaker or a subwoofer. In some embodiments, the speaker 13 may not be provided.

[0032] The main control board 15 is installed inside the housing 12. The main control board 15 is equipped with a wireless communication module 151 and a memory card connector 152. The memory card connector 152 is equipped with a memory card, which is mainly used to store music and white noise, including but not limited to rain sounds, ocean waves sounds, stream sounds, mountain stream sounds, wood burning sounds, etc. The speaker 13 and the loudspeaker 4 are electrically connected to the main control board 15.

[0033] The wireless communication module 151 is one or two of Bluetooth, WiFi, or 4G communication modules; users can wirelessly communicate with the wireless communication module 151 through mobile phones or other terminals to control the entire sleep aid speaker, which is 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] An angle adjustment structure 5 is provided between the angle adjustment seat 2 and the speaker body 1. The angle adjustment seat 2 and the speaker body 1 are adjusted through the angle adjustment structure 5 and can be positioned after the angle is adjusted, so as to ensure that the angle adjustment seat 2 is stably positioned on the speaker body 1 after the angle is adjusted.

[0038] Specifically, the angle adjustment structure 5 includes: a gear plate 51 and a positioning module 52.

[0039] The gear plate 51 is fixed to the outside of the angle adjustment seat 2, and the outer side of the gear plate 51 is provided with a plurality of gear slots 511.

[0040] The positioning module 52 includes a movable positioning block 521 installed inside the speaker body 1 and a spring 522 disposed between the positioning blocks 521 and the speaker body 1. The positioning block 521 protrudes outward under the elastic force of the spring and is engaged in one of the position slots 511, thereby achieving positioning. When it is necessary to adjust the angle adjustment seat 2 relative to the speaker body 1, the angle adjustment seat 2 is directly rotated, forcing the positioning block 521 to leave the previous position slot 511 and compressing the spring to retract until the positioning block 521 enters the next position slot 511. The positioning block 521 protrudes outward under the elastic force of the spring and is engaged in the next position slot 511, thereby achieving the purpose of position adjustment. This ensures that the angle adjustment seat 2 and the speaker body 1 can be positioned after the angle is adjusted by the angle position adjustment structure 5, and that the angle adjustment seat 2 is stably positioned on the speaker body 1 after the angle adjustment.

[0041] The gear plate 51 is provided with a positioning hole 512, and the angle adjustment seat 2 is formed with a positioning post 21 on the outside. The positioning post 21 is embedded in the positioning hole 512 to form a positioning and thus achieve the purpose of pre-positioning. After the screw passes through the through hole of the gear plate 51, it is screwed and fixed to the screw hole on the outside of the angle adjustment seat 2. Its assembly structure is simpler and the assembly efficiency is higher.

[0042] The speaker body 1 is provided with a mounting groove 11 for mounting the angle adjustment seat 2. Specifically, the mounting groove 11 is provided on the cabinet 12. The angle adjustment seat 2 is hinged to the inner walls of the mounting groove 11 on both sides by hinges 22. 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 groove, and an arc protrusion 513 is formed between two adjacent gear slots 511, which allows 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 allows the positioning block 521 to slide more smoothly to the next gear slot 511 after leaving the previous gear slot 511.

[0043] The inner walls on both sides of the mounting groove 11 are formed with a first stroke limiting protrusion 111 and a second stroke limiting protrusion 112. The stop plate 51 is placed between the first stroke limiting protrusion 111 and the second stroke limiting protrusion 112, and can rotate between the first stroke limiting protrusion 111 and the second stroke limiting protrusion 112 at intervals. It can limit the rotation angle of the angle adjustment seat 2, and prevent the positioning block 521 from being unable to enter the next stop groove 511 after the angle adjustment seat 2 rotates, which would cause the angle adjustment seat 2 to fail to be positioned. That is, it ensures that the positioning block 521 can always be locked in a stop groove 511, thus ensuring product quality.

[0044] The inner wall of the mounting groove 11 is provided with a receiving groove 113. 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 protruding edge 501 that protrudes from the inside to the outside. The opening of the receiving groove 113 is provided with a protruding part 114 that protrudes from the outside to the inside and is used to block the protruding edge 501. This ensures that only the front end of the positioning block 521 protrudes out of the receiving groove 113, so that the positioning block 521 will not completely detach from the receiving groove 113 and the angle gear adjustment structure 5 is always in an effective state.

[0045] In summary, when this invention is in operation, the sound waves emitted by the speaker 4 will be reflected after encountering the wall of the waveguide 3 because the angle α formed between the speaker's central axis normal and the wall of the waveguide 3 is greater than 0° and less than 180°. The user can adjust the direction of sound wave propagation after reflection by adjusting the angle adjustment seat 2 relative to the speaker body 1, thereby achieving directional sound generation. This results in a strong sound pressure in a certain direction. Furthermore, the secondary reflection from the ceiling, walls, or floor of the room allows the user to perceive part of the sound as coming from 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. This makes the sound field wider and more natural, allowing the reproduced sound effects to be closer to and more realistic than the source, leading to greater relaxation and enjoyment for the user and enhancing the sleep-aiding effect.
