Description

Technical Field

[0001] The utility model relates to the technical field of bone conduction sound generation, and in particular to a sleep aid instrument and a sleep aid system. Background Art

[0002] Bone conduction speakers, also known as resonance speakers, are a type of speaker product that uses bone conduction technology. Its working principle is to convert sound signals into vibration signals, which directly act on the contact medium (such as human bones) to make the medium resonate and transmit sound. The sound transmission method of bone conduction speakers is different from the air conduction of traditional speakers. It avoids the noise that may be generated by traditional speakers and interferes with the surrounding environment and others. It helps to create a quiet and comfortable sleeping environment and can meet people's needs for high-quality sleep.

[0003] Most existing bone conduction speakers for sleep aid are single speakers that can be placed under the pillow when in use. However, the volume and sound field of a single bone conduction sleep aid speaker are relatively small, and its effect is limited by the placement of the speaker, which does not provide a good sleep aid experience. If multiple bone conduction sleep aid speakers are set up, there are problems such as difficulty in storage, inconvenience in charging, and inability to control synchronous playback.

[0082] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0083] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0084] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0085] Example 1

[0086] As mentioned in the background technology, the existing bone conduction speakers for sleep aid are mostly single speakers, which can be placed under the pillow when in use. However, the volume and sound field of a single bone conduction sleep aid speaker are relatively small, and its effect is limited by the placement of the speaker, and it cannot provide a good sleep aid experience. If multiple bone conduction sleep aid speakers are set up, there are problems such as difficulty in storage, inconvenience in charging, and inability to control synchronous playback.

[0087] In order to solve the above technical problems, this embodiment provides a sleep aid device, such as Figure 1-2 As shown, the sleep aid device includes at least two bone conduction speakers 1 and a storage device for storing the bone conduction speakers 1, the bone conduction speakers 1 have a first connector 116 and an audio signal receiving module, the storage device has a storage cavity 211 corresponding to the at least two bone conduction speakers 1, the storage cavity 211 has a second connector 2114, and the second connector 2114 is configured to be connected to the first connector 116 for charging; the storage device also has an audio signal transmitting module, and the audio signal transmitting module is configured to communicate with the audio signal receiving module to synchronously transmit audio signals to the at least two bone conduction speakers 1.

[0088] By adopting the above technical solution, the problems of difficult storage, inconvenient charging and inability to control synchronous playback that arise when multiple bone conduction sleep-aiding speakers are set up are solved. In the sleep-aiding scenario, the user takes out at least two bone conduction speakers 1 from the storage device. When the first connector 116 of the bone conduction speakers 1 is disconnected from the second connector 2114 of the storage device, the audio signal transmitting module of the storage device establishes a communication connection with the audio signal receiving module of the bone conduction speaker 1, so that the storage device synchronously transmits audio signals to the at least two bone conduction speakers 1 taken out. Furthermore, even if the at least two bone conduction speakers are placed in different positions (such as in different corners of the bed), the user can hear the synchronous sleep-aiding sounds transmitted from each bone conduction speaker. The overall sound field is wider, which can produce a stronger sense of immersion, making people feel as if they are in an environment surrounded by sleep-aiding sounds, thereby improving the sleep-aiding effect. When the user does not need to use the bone conduction speakers, each bone conduction speaker can be put back into the storage device. When the first connector of the bone conduction speaker is reconnected with the second connector of the storage device, the storage device can charge the bone conduction speaker for the next use.

[0089] like Figure 2 As shown, the storage device may include a storage box 21 and a storage shell 22 for accommodating the storage box 21. The storage box 21 may have four storage cavities 211, which may correspondingly store four bone conduction speakers 1. When using, the user may choose to take out 2-4 of the bone conduction speakers 1 according to actual needs. In other alternative embodiments, the number of bone conduction speakers 1 and the corresponding storage cavities 211 may be 2, 3, 5, or more.

[0090] Optionally, the shapes and structures of the bone conduction speakers 1 are the same, and accordingly, the main shapes and structures of the cavities of the storage cavities 211 are also the same, so that mass production can be facilitated. In other alternative embodiments, the shapes and structures of the bone conduction speakers 1 may also be different.

[0091] Alternatively, if Figure 3 As shown, the bone conduction speaker 1 has a shell 12, a top cover 13 and a bottom shell 11, and the shell 12, the top cover 13 and the bottom shell together enclose an installation space. The main body of the bone conduction speaker 1 can be roughly hexagonal. In other alternative embodiments, the main body of the bone conduction speaker 1 can be circular or other polygonal shapes such as triangles and squares.

[0092] Optionally, the top cover 13 covers the outer shell 12 from above, and the top cover 13 can be used as a decorative panel or a display screen, etc.

[0093] Optionally, the bone conduction speaker 1 can be connected to the storage cavity 211 through the bottom shell 11, the first connector 116 is arranged on the bottom shell 11, and the second connector 2114 is arranged at the bottom of the storage cavity 211, so that when the bone conduction speaker 1 is placed in the storage cavity 211, the first connector 116 and the second connector 2114 are connected to achieve charging.

[0094] Alternatively, if Figure 3-7 As shown, the bottom shell 11 has a reference bottom wall 111, and the reference bottom wall 111 has a first reference end face 1111 facing outward relative to the bottom shell 11 and a second reference end face 1112 facing inward relative to the bottom shell 11; along the height direction of the bone conduction speaker 1, the bottom shell 11 has a positioning boss 113 protruding downward from the reference bottom wall 111, and the positioning boss 113 has a boss bottom wall 1131, and the boss bottom wall 1131 has a first boss end face 11311 facing outward relative to the bottom shell 11 and a second boss end face 11312 facing inward relative to the bottom shell 11; by providing the positioning boss 113, when the bone conduction speaker 1 is placed in the storage cavity 211, the bone conduction speaker 1 can be positioned conveniently and quickly.

[0095] Alternatively, if Figure 3-7 As shown, the middle portion of the boss bottom wall 1131 has a through first opening 115, as shown in FIG. Figure 12-13 As shown, the bone conduction speaker 1 has a vibration plate 16, and a non-slip pad 17 is provided at the bottom end of the vibration plate 16. The first opening 115 is used to at least make the non-slip pad 17 protrude from the bottom shell 11, so that when the bone conduction speaker 1 is placed on a vibration medium, the vibration plate 16 can transmit the vibration signal to the vibration medium through the non-slip pad 17, and the non-slip pad 17 can play a buffering and anti-slip effect; in other optional embodiments, the vibration plate 16 can also pass through the first opening 115 and protrude downward from the bottom shell 11. The first opening 115 is a circular hole. In other optional embodiments, the hole shape of the first opening 115 can be adaptively designed according to the shapes of the vibration plate 16 and the non-slip pad 17, such as square, hexagonal, etc.

[0096] Alternatively, if Fig.12 As shown, the anti-skid pad 17 and the vibration plate 16 are not in contact with the bottom shell 11, that is, the anti-skid pad 17 and the vibration plate 16 are both arranged to avoid the air from the bottom shell 11, so as to ensure the vibration transmission effect of the vibration plate 16 and the anti-skid pad 17; further optionally, at least a part of the vibration plate 16 is located in the bottom shell 11, and a resonance cavity is formed between the vibration plate 16 and the bottom shell 11, and the resonance cavity can enhance the resonance conduction effect of the bone conduction speaker 1.

[0097] Alternatively, if Figure 4-7 As shown, the horizontal plane projection of the positioning shoulder 113 is located within the horizontal plane projection range of the reference bottom wall 111, that is, the contour of the positioning shoulder 113 does not exceed the contour of the reference bottom wall 111, and the positioning shoulder 113 is formed inside the reference bottom contour; the bottom shell 11 also has a reference side wall 112 extending upward from the circumferential contour of the reference bottom wall 111, that is, the reference side wall 112 surrounds the outer circumferential contour of the reference bottom wall 111 and extends upward, and the reference side wall 112 is used to cooperate with the shell 12; the positioning shoulder 113 has a shoulder side wall 1132, and the shoulder side wall 1132 has a direction toward the reference side wall 111 The extended positioning portion 11321 extending from the reference side wall 112 is provided; the extended positioning portion is extended to align with the contour of the reference side wall 112, so that a reference guide surface 114 extending from the top surface of the reference side wall 112 to the first convex shoulder end surface 11311 is formed in the height direction of the bone conduction speaker 1, and a reference guide structure 1141 is provided on the reference guide surface 114 extending from top to bottom; through the above-mentioned structural setting, the positioning convex shoulder 113 has an extended positioning section extending toward the reference side wall 112 when its main body shape is roughly annular around the first opening 115, and the extended positioning section can further enhance the positioning effect of the bottom shell 11. In addition, the reference guide surface 114 formed by the extended positioning section of the positioning convex shoulder 113 and the reference side wall 112 can well guide and position the bottom shell 11 in the height direction of the bone conduction speaker 1, achieving a foolproof effect. Furthermore, the reference guide structure 1141 includes a guide recess. In other optional embodiments, the reference guide structure 1141 may also be in the form of a convex rib or the like.

[0098] Alternatively, if Figure 4-7 As shown, the second shoulder end surface 11312 is provided with a first mounting portion 113121, and the first mounting portion 113121 is configured to mount the first connector 116; further, the first shoulder end surface 11311 has an extended positioning end surface 113111 corresponding to the extended positioning portion 11321, and the first mounting portion 113121 is provided at a position on the second shoulder end surface 11312 corresponding to the extended positioning end surface 113111, as shown in FIG. Figure 6-7As shown, the second reference end face 1112 of the reference bottom wall 111 and the second boss end face 11312 form an internal shoulder inside the shell, and the internal shoulder is disconnected at a position corresponding to the reference guide surface 114 to form a mounting notch, and the second boss end face 11312 extends from the mounting notch to the reference side wall 112, and the first connector 116 is mounted on the second boss end face 11312 at the mounting notch, and the mounting notch makes full use of the extended positioning section of the positioning boss 113, providing a relatively spacious installation position for the first connector 116 in the limited installation space inside the bottom shell 11, and since the first mounting portion 113121 is simultaneously arranged at a position corresponding to the extended positioning section and corresponding to the reference guide surface 114, the first mounting portion 113121 can be well guided and positioned both in the height direction and in the horizontal direction of the bone conduction speaker 1, thereby ensuring accurate positioning of the charging position. Of course, in other optional embodiments, the installation notch may not be provided, and the first installation portion 113121 may be directly provided on the second reference end surface 1112 of the reference bottom wall 111. Furthermore, the first installation portion 113121 may be provided on the second reference end surface 1112 at a position corresponding to the extended positioning end surface 113111.

That is, when the reference side wall 112 is hexagonal in shape, the reference guide structure 1141 is formed at the junction of two adjacent side wall surfaces, and accordingly, the position of the first mounting portion 113121 is also arranged at the junction corresponding to the two adjacent side wall surfaces, and the corner space of the junction can provide a larger installation space for the first connector 116 than the other side positions.

[0100] Alternatively, if Figure 3As shown in FIG. 8 , the housing 12 is a hollow columnar structure, the top of the housing 12 has a second opening 122, the top cover is configured to cooperate with the second opening 122 to close the second opening 122, the bottom of the housing 12 has a third opening 123, the bottom shell 11 is configured to cooperate with the third opening 123, and the housing, the top cover and the bottom shell together form a mounting cavity.

Specifically, the inner wall surface of the housing 12 fits the outer wall surface of the reference side wall 112, and the reference side wall 112 protrudes downward relative to the housing 12, thereby forming a reference positioning step 118 relative to the housing 12, and the reference positioning step 118 enhances the positioning effect of the bone conduction speaker 1 in the storage cavity 211. In other optional embodiments, the reference side wall 112 can use its outer wall surface to fit with the inner wall surface of the reference side wall 112 , so as to achieve the matching installation of the bottom shell 11 and the outer shell 12 .

[0101] Alternatively, if Figure 14-15 As shown, the cavity of the storage cavity 211 may be designed with a positioning and mounting structure that cooperates with the outer shell 12 and the bottom shell 11 of the bone conduction speaker 1.

[0102] In other optional embodiments, the reference side wall 112 may not protrude downward relative to the housing 12, and the reference positioning step 118 may not be provided, that is, the reference bottom wall 111 may be coplanar with the bottom of the housing 12, or even concave upward relative to the housing 12, and positioning may be achieved by designing a corresponding matching structure in the storage cavity 211. In other optional embodiments, the bottom shell 11 may not have the reference side wall 112, and the reference bottom wall 111 may be directly used to match and install with the housing 12.

[0103] Alternatively, if Figure 3 ,8, a shell guide structure 121 is provided on the shell 12 corresponding to the reference guide structure 1141 and extending from top to bottom, and the shell guide structure 121 has the same shape as the reference guide structure 1141; Figure 14-15As shown, the cavity shape of the storage cavity 211 is adapted to the shape of the bone conduction speaker 1, and the cavity sidewall of the storage cavity 211 is provided with a cavity guide structure 2111 that matches the reference guide structure 1141. That is, the shell guide structure 121 can be a guide recess with the same shape as the reference guide structure 1141, and correspondingly, the cavity guide structure 2111 is a guide convex rib; in other optional embodiments, the shell guide structure can be a guide convex rib with the same shape as the reference guide structure, and correspondingly, the cavity guide structure is a guide recess.

[0104] Alternatively, if Figure 6-7 As shown, the first connector 116 includes a conductive contact and a contact plate for carrying the conductive contact, the contact plate is installed on the first mounting portion 113121 of the second convex shoulder end surface 11312, and the convex shoulder bottom wall 1131 is provided with a conductive socket 1133 corresponding to the conductive contact; the second connector 2114 is a conductive pin, and the conductive pin corresponds to the conductive contact one by one; the number of the conductive contact and the conductive pin are two respectively, and in other optional embodiments, the number of the conductive contact and the conductive pin can be three or more respectively. In other optional embodiments, the contact plate can be directly arranged on the second reference end surface 1112 of the reference bottom wall 111, and then, a conductive socket is arranged on the reference bottom wall 111. In other replaceable embodiments, the first connector 116 can be a conductive pin, and the second connector 2114 can include a conductive contact. In this case, the conductive socket on the convex shoulder bottom wall is used to plug the conductive pin.

[0105] In summary, by providing matching positioning structures and guiding structures in the bone conduction speaker 1 and the storage cavity 211 , the bone conduction speaker 1 can be quickly and accurately placed in the storage cavity 211 and achieve charging connection.

[0106] Alternatively, if Figure 8-13As shown, the bone conduction speaker 1 also has a speaker main shell 14, which is sleeved in the outer shell 12, and is used to install various main components of the speaker, such as the main circuit board 18, the battery 19, the vibration transducer 15, the vibration plate 16, etc. The shape of the speaker main shell 14 is adapted to the shape of the outer shell 12, and a main shell guide structure 141 is provided on the side wall of the speaker main shell 14 corresponding to the reference guide structure 1141 and the guide structure of the outer shell 12, extending from top to bottom. The main shell guide structure 141 has the same shape as the outer shell guide structure 121 and the reference guide structure 1141, that is, the same guide recess or guide convex rib or other structures. Through the matching arrangement of the main shell guide structure 141 with the outer shell guide structure 121 and the reference guide structure 1141, it is convenient to quickly locate and align the bottom shell 11 with the outer shell 12 and the speaker main shell 14 during the installation process.

[0107] Alternatively, if Figure 8-13 As shown, in order to realize the installation between the bottom shell 11 and the outer shell 12 and the speaker main shell 14, the inner wall surface of the outer shell 12 is provided with a first abutting convex edge 124 extending inwardly in the horizontal direction near the third opening 123, and the first abutting convex edge 124 has a first abutting surface and a second abutting surface in the horizontal direction, and a third abutting surface in the vertical direction, wherein the first abutting surface is the upper surface of the first abutting convex edge 124, and the second abutting surface is the lower surface of the first abutting convex edge 124. The first abutting surface is used to cooperate with the bottom surface of the speaker main shell 14, so as to limit the speaker main shell 14 in the up and down directions, and the speaker main shell 14 is assembled from the second opening 122 downward to the outer shell 12 until its bottom wall abuts against the first abutting surface. The second abutment surface is used to cooperate with the top surface of the reference side wall 112 (that is, the top surface of the bottom shell 11), so as to limit the bottom shell 11 in the up and down directions. The bottom shell 11 is assembled upward from the third opening 123 to the outer shell 12 until its top surface abuts against the second abutment surface.

[0108] Alternatively, if Figure 8-13As shown, the bottom wall of the speaker main shell 14 is extended downwardly to form a second abutment protrusion 142, the second abutment protrusion 142 is perpendicular to the first abutment protrusion 124, and the second abutment protrusion 142 has a fourth abutment surface in the horizontal direction (i.e., the bottom surface of the second abutment protrusion 142) and a fifth abutment surface in the vertical direction. The fourth abutment surface is used to cooperate with the second reference end surface 1112 of the reference bottom wall 111, so as to limit the bottom shell 11 in the up and down directions. The bottom shell 11 is assembled upward from the third opening 123 to the outer shell 12. While the top surface of the bottom shell 11 abuts against the second abutment surface, the second reference end surface 1112 of the reference bottom wall 111 abuts against the fourth abutment surface of the second abutment protrusion 142. Through the above structure, multiple limitations in the up and down directions are realized between the bottom shell 11 and the outer shell 12 and the main shell 14 of the speaker, so that the reference side wall 112 of the bottom shell 11 protrudes downward relative to the outer shell 12, thereby forming the reference positioning step relative to the outer shell 12. The fifth abutment surface of the second abutment flange 142 is used to cooperate with the third abutment surface of the first abutment flange 124 and the reference side wall 112 of the bottom shell 11, so as to circumferentially limit the main shell 14 and the bottom shell 11 of the speaker, so that the main shell 14 and the bottom shell 11 of the speaker are more firmly installed in the outer shell 12.

[0109] Alternatively, if Figure 6-13 As shown, the bottom wall of the speaker main shell 14 is provided with a plurality of first fastener mounting holes 144, and the interior of the bottom shell 11 is provided with a plurality of fastener mounting columns 117 at corresponding positions of the reference bottom wall 111, and the plurality of fastener mounting columns 117 are provided with second fastener mounting holes 1171, the first fastener mounting holes 144 are through holes, and the second fastener mounting holes 1171 are blind holes, and the positions of the first fastener mounting holes 144 and the second fastener mounting holes 1171 correspond one by one, thereby realizing a fastening connection between the speaker main shell 14 and the bottom shell 11, and since the outer shell 12 is already tightly abutted against the speaker main shell 14 through the first abutting protrusion 124, therefore, when realizing a fastening connection between the speaker main shell 14 and the bottom shell 11, a fastening installation is also realized between the outer shell 12 and the bottom shell 11 and the speaker main shell 14. Furthermore, the aperture of the first fastener mounting hole 144 is larger than the aperture of the second fastener mounting hole 1171 . In order to avoid the fastener, a fastener avoidance groove 1241 corresponding to the position of the first fastener mounting hole 144 is also provided on the first abutting flange 124 of the shell 12 .

The vibration transducer 15 is provided with a mounting flange 151 in the circumference, and the top surface of the mounting flange 151 abuts against the bottom wall of the speaker main shell 14. The limiting flange 145 cooperates with the outer circumference of the mounting flange 151 to limit the circumference of the vibration transducer 15. The first hook 143 is used to engage with the bottom surface of the mounting flange 151, thereby realizing the clamping and positioning installation of the vibration transducer 15 by the speaker main shell 14. It should be noted that the bottom of the vibration transducer 15 is connected to the vibration disk 16 by bonding or the like, and the bottom end of the vibration disk 16 is connected to the anti-slip pad 17 by bonding or the like. This specific connection relationship is not shown in the enumerated drawings.

The above-mentioned design of the access opening 212 makes the top of the bone conduction speaker 1 protrude from the access opening 212 when the bone conduction speaker 1 is placed in the storage cavity 211. In this way, when the user takes the bone conduction speaker 1 from the storage cavity 211, the user can directly grasp the part of the bone conduction speaker 1 protruding from the access opening 212, thereby improving the convenience of taking.

[0112] Alternatively, if Figure 16-19As shown, the storage device includes a storage shell 22, and the storage shell 22 is provided with a sixth opening 221 at one end in the length direction thereof, and the storage box 21 is installed in the storage shell 22 in a pullable manner from the sixth opening 221; further optionally, the storage shell 22 is provided with a cover 222 at the other end in the length direction thereof, and the storage box 21 is provided with a second hook 213 at one end facing the cover 222, and the cover 222 is provided with an elastic claw that cooperates with the second hook 213.

When the user needs to pull out the storage box 21, the user first presses the end of the storage box 21 corresponding to the sixth opening 221, so that the end of the storage box 21 corresponding to the sixth opening 221 pops out of the storage shell 22 and is unlocked, thereby facilitating the user to pull out the storage box 21.

[0117] Example 2

[0118] Embodiment 2 provides a sleep aid device, and the sleep aid device of embodiment 2 has the same structure as that of embodiment 1. The difference between embodiment 2 and embodiment 1 is that the positioning boss 113 protruding downward from the reference bottom wall 111 in embodiment 1 is not provided on the reference bottom wall 111 in embodiment 2, but the reference bottom wall 111 is directly used to cooperate with the storage cavity 211 for installation and positioning.

[0124] When in use, the user takes out the bone conduction speaker 1 in the sleep aid device and places it in a suitable position. The suitable position may be, for example, at least two of the four corner positions of the bed. Preferably, there are four bone conduction speakers 1 in the sleep aid device, and the four bone conduction speakers 1 are respectively placed in the four corner positions of the bed after being taken out.
