Description
Technical Field
[0001] The invention belongs to the technical field of audio equipment, and in particular relates to a speaker with wireless charging function. Background Art
[0002] A speaker is a device that can convert electrical signals into sound signals. It is used to play various audio content such as music, movie sound effects, and broadcasts. Its main function is to amplify, process, and restore audio signals so that people can hear clear and pleasant sounds. Depending on the usage scenario, speakers can be roughly divided into home speakers, portable speakers, and professional speakers. At the same time, with the development of the times, speakers that were originally larger in size have been given more and more functions, such as wireless charging.
[0003] Most home speakers are placed in a fixed position for use, so they are often large in size, which makes the sound quality of the speakers better than headphones. When using the speakers, the user needs to sit roughly facing the direction of the speakers to better enjoy the music. The position in this direction can be called the appreciation position. However, during use, not all users like to sit quietly and enjoy music. Many users like to enjoy music while cooking or doing exercise. The speakers originally placed in a fixed position are difficult to move easily due to their size limitations. Therefore, for these users, the playback effect of the speakers will be reduced, and in order not to disturb the neighbors, they cannot choose to increase the volume to enhance the playback effect of the speakers. As a result, such large speakers can only be used in scenarios where users sit quietly and enjoy music. Summary of the invention
[0004] The technical problem to be solved by the present invention is to overcome the disadvantages of the above-mentioned prior art and provide a speaker with wireless charging.
[0005] The technical solution adopted to solve the above technical problems is:
[0006] A speaker with wireless charging, comprising a central speaker and two side speakers, wherein the two side speakers are respectively hinged to the side walls of the central speaker, a wireless charging module is arranged on the top of the side speakers, a PIR sensor is arranged at the bottom of the front end of the side speakers, and a driving wheel is also arranged at the bottom of the side speakers, wherein the driving wheel is electrically connected to the PIR sensor, the driving wheel abuts against the desktop, and the driving wheel is arranged at an angle;
[0007] An arc-shaped spring sheet is installed between the side speaker and the center speaker, a transverse groove is opened on the back of the center speaker, a transverse block is slidably connected in the transverse groove, one end of the arc-shaped spring sheet away from the side speaker is fixedly connected to the side wall of the transverse block, and a transverse mechanism driven by the arc-shaped spring sheet is installed on the side wall of the transverse block;
[0008] Two supporting blocks are arranged at the bottom of the central speaker and the side speakers, each of the supporting blocks is located between the central speaker and the side speakers, the bottom of the supporting block is against the desktop, and a lifting mechanism is arranged in the supporting block.
[0009] Through the above technical solution, a PIR sensor for detecting the movement of the user and a movable side speaker are provided, so that when the user moves, the speaker can move with the user, thereby ensuring the playback effect of the speaker.
[0010] Furthermore, a buffer groove is provided on the back side wall of the side speaker, a buffer block is slidably connected in the buffer groove, and the end of the arc-shaped spring piece away from the transverse displacement block is fixedly connected to the side wall of the buffer block.
[0011] Through the above technical solution, when the PIR sensor detects the movement of the user, the driving wheel will drive the side speaker to move. The setting of the buffer groove and the buffer block can prevent the arc-shaped spring piece from driving the transverse block to move at the first time, thereby providing enough time for the long board to drive the lifting mechanism, so that the lifting mechanism will be triggered first.
[0012] Furthermore, the side walls at both ends of the transverse moving block are respectively fixedly connected with telescopic springs, and the ends of the two telescopic springs away from the transverse moving block are respectively fixedly connected to the side walls of the transverse groove.
[0013] Through the above technical solution, the telescopic springs arranged on both sides of the transverse moving block will respectively apply elastic force to the transverse moving block, so that in the absence of external force, the transverse moving block will be in the middle position of the transverse groove, and when the arc-shaped spring piece drives the transverse moving block to move, the telescopic spring will accumulate potential energy, and when the external force is lost, it will drive the transverse moving block and the push rod to return to their original position.
[0014] Furthermore, the transverse movement mechanism includes a pushing rod, a long plate and two staggered axis racks, one end of the pushing rod is fixedly connected to the side wall of the transverse movement block, and the other end is fixedly connected to the side wall of the long plate, a through groove is provided at the bottom of the central speaker, and movement grooves are respectively provided at the bottom of the two side speakers, and the two movement grooves are open at one end facing the through groove, the movement groove is connected to the through groove, the long plate is slidably connected to the side wall of the through groove, and the two staggered axis racks are respectively fixedly arranged on the side walls of the long plate.
[0015] Through the above technical solution, when the side speakers are driven to rotate, the arc-shaped spring sheet arranged on the back of the side speakers will cause the transverse block to move along the transverse groove, and then the push rod will drive the long board to move along the through groove, and the staggered axis rack arranged on the side wall of the long board will drive the staggered axis gear at the corresponding position to rotate, thereby driving the lifting mechanism.
[0016] Furthermore, the push rod is "L"-shaped, the two arc-shaped spring pieces are respectively fixedly arranged on the side walls at both ends of the transverse movement block, and the push rod is fixedly arranged at the center position of the transverse movement block.
[0017] Through the above technical solution, since the two side speakers can rotate, the two arc-shaped spring pieces need to be able to drive the transverse movement block to move together, so the two arc-shaped spring pieces need to be respectively arranged at both ends of the transverse movement block to drive the transverse movement block to move in the transverse groove.
[0018] Furthermore, the support block includes a top plate, two fixed columns and two movable columns. The top plate is arranged at the bottom of the central speaker and the side speakers, the two fixed columns are respectively fixed at the bottom of the top plate, and the two movable columns are respectively movably sleeved on the side wall of the fixed column away from the top plate.
[0019] Through the above technical solution, it can be seen from the attached drawings that the top plate arranged at the bottom of the center speaker and the side speakers is inclined. The top plate spanning the two speakers can stably support the two speakers. Even after the side speakers are rotated, the remaining center speaker can also stay stably in the initial position.
[0020] Furthermore, a groove is provided on the top of the top plate, and the position of the groove is consistent with the position of the long plate. A fixing rod is fixedly connected to one end of the top of the top plate, and the fixing rod is fixedly connected to the bottom of the center speaker at one end away from the top plate. An arc groove is provided on the other end of the top of the top plate, and one end of the arc groove is open. A sliding rod is slidably connected in the arc groove, and the other end of the sliding rod is fixedly connected to the bottom of the side speaker.
[0021] Through the above technical solution, the setting of the groove allows the long board to easily pass through the position of the top plate when moving with the push rod, and the setting of the sliding rod and the arc groove allows the side speaker to easily leave the position of the top plate when rotating.
[0022] Furthermore, a cavity is provided on the top of the top plate, in which an electric push rod is installed, the electric push rod is electrically connected to the PIR sensor, a clamping rod is fixedly connected to the output end of the electric push rod, a clamping groove is provided on the side wall of the sliding rod, and the clamping rod passes through the side wall of the arc groove and is clamped with the side wall of the clamping groove.
[0023] Through the above technical solution, when the user passes by the PIR sensor, the electric push rod will be activated, thereby causing the card rod to disengage from the card slot, thereby facilitating the rotation of the side speaker, ensuring that the side speaker can move with the user, thereby ensuring the playback effect of the side speaker.
[0024] Furthermore, the lifting mechanism includes staggered shaft gears, a rotating rod, two first bevel gears, two second bevel gears and two threaded rods, a rotating groove is opened in the groove, the staggered shaft gears are located in the rotating groove, a working chamber is opened in the top plate, the rotating rod is rotatably connected to the side wall of the working chamber, the staggered shaft gears are fixedly connected to the side wall of the rotating rod, the staggered shaft gears are meshed with the staggered shaft rack, the two first bevel gears are respectively fixedly arranged on the side walls on both sides of the rotating rod, and the bottoms of the two second bevel gears are respectively fixedly connected with blank rods, the blank rods pass through the side walls of the working chamber, the second bevel gears are meshed with the first bevel gears, the blank rods are fixedly connected to the threaded rod at one end away from the second bevel gears, the threaded rod passes through the side wall of the fixed column, the side wall of the movable column is opened with a threaded groove, and the threaded rod is threadedly connected to the inner wall of the threaded groove.
[0025] Through the above technical solution, when the long board is driven to move by the push rod, the staggered axis rack will drive the staggered axis gear to rotate. Although the angle between the two is not the standard 90°, the characteristics of the staggered axis gear enable it to still be driven to rotate, thereby causing the first bevel gear to drive the second bevel gear to rotate, and finally the movable column is raised to a position, so that the other side speaker that does not need to move is combined with the center speaker into a whole, thereby ensuring the overall stability.
[0026] Furthermore, a bearing is provided at the bottom of the working chamber, the outer portion of the bearing is fixedly connected to the side wall of the working chamber, and the inner wall of the bearing is fixedly connected to the side wall of the blank rod.
[0027] Through the above technical solution, the setting of the bearing allows the threaded rod to be stably driven by the second bevel gear to rotate, and can also ensure the stability of the rotation of the blank rod and the threaded rod, while ensuring that the two can always be in a vertical state to avoid unnecessary friction losses.
[0028] The beneficial effects of the present invention are as follows:
[0029] (1) The present invention provides a central speaker in the middle and two movable side speakers on both sides, and also provides a PIR sensor for detecting the movement of the user. When the user moves, the side speakers can rotate with the user, thereby ensuring the sound playing effect for the user. At this time, the remaining two speakers will be combined into a whole, thereby ensuring that they will not be offset by the side speakers during the rotation process.
[0030] (2) The present invention provides an inclined top plate at the bottom of the central speaker and the side speaker. The top plate spanning the two speakers can stably support the two speakers at the same time. When the user passes by the PIR sensor, the electric push rod will be activated, thereby disengaging the latch rod from the latch slot, thereby facilitating the rotation of the side speaker and ensuring that the side speaker can move with the user. Even after the side speaker rotates, the remaining central speaker can stably stay in the initial position under the action of the support block;
[0031] (3) The present invention sets a fixed column and a movable column in the support block, so that when the long board moves, the staggered axis rack will drive the staggered axis gear to rotate. Although the angle between the two is not the standard 90 degrees, the teeth of the staggered axis gear itself are also inclined, so it can still be driven. The rotating rod driven by the staggered axis gear to rotate will cause the first bevel gear to drive the second bevel gear to rotate, and finally the movable column is raised to a position, so that the other side speaker that does not need to move is combined with the center speaker into a whole, thereby ensuring the overall stability.

DETAILED DESCRIPTION
[0040] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.
[0041] like Figure 1 one Figure 7 As shown, a speaker with wireless charging in this embodiment includes a central speaker 1 and two side speakers 2. The two side speakers 2 are hinged to the side walls of the central speaker 1 respectively. A wireless charging module 3 is arranged on the top of the side speakers 2. Figure 1 It can also be seen that a physical button is provided on the top of the center speaker 1, so there is not enough space to place the wireless charging module 3, and the side speakers 2 that can be rotated are more convenient for placing the devices that need to be charged, because the side speakers 2 can rotate with the user. When the user needs to retrieve the wireless charging device, the side speakers 2 will be in the direction facing the user, which is more convenient for the user to retrieve the device. A PIR sensor 4 is installed at the bottom of the front end of the side speaker 2, and a driving wheel 5 is also installed at the bottom of the side speaker 2. The driving wheel 5 is electrically connected to the PIR sensor 4, and the driving wheel 5 is against the desktop. The driving wheel 5 is tilted. Since the driving wheel 5 is tilted, the side speaker 2 will also rotate around the position where it is hinged with the center speaker 1, thereby moving in the direction of the user.
[0042] PIR sensor 4 is a device widely used in motion detection. It senses the presence and movement of people by detecting infrared radiation emitted by the human body. The human body has a constant body temperature, generally at 37 degrees, so it will emit infrared rays with a specific wavelength of about 10μm. PIR sensor 4 works by detecting infrared rays of about 10μm emitted by the human body. The specific model can be HC-SR501, which is low-priced and has stable technical performance.
[0043] When one of the PIR sensors 4 is triggered, while driving the side speaker 2 to move, the circuit where the other PIR sensor 4 is located will be disconnected, and other people passing by the other PIR sensor 4 will not drive the side speaker 2 to move in that direction.
[0044] Combination Figure 2 and Figure 3 As shown, an arc-shaped spring piece 6 is installed between the side speaker 2 and the center speaker 1, a buffer groove 9 is opened on the back side wall of the side speaker 2, and a buffer block 10 is slidably connected in the buffer groove 9. The end of the arc-shaped spring piece 6 away from the transverse block 8 is fixedly connected to the side wall of the buffer block 10. When the PIR sensor 4 detects the movement of the user, the driving wheel 5 will drive the side speaker 2 to move. The setting of the buffer groove 9 and the buffer block 10 can prevent the arc-shaped spring piece 6 from driving the transverse block 8 to move at the first time, thereby delaying the timing of the movement of the long board 13, so that the side speaker 2 will not drive the movable column 19 to rise when it rotates at a small angle.
[0045] A transverse groove 7 is provided on the back of the central speaker 1, and a transverse block 8 is slidably connected in the transverse groove 7. The end of the arc-shaped spring piece 6 away from the side speaker 2 is fixedly connected to the side wall of the transverse block 8, and the side walls at both ends of the transverse block 8 are fixedly connected with telescopic springs 11. The two telescopic springs 11 are fixedly connected to the side walls of the transverse groove 7 at one end away from the transverse block 8. The telescopic springs 11 arranged on both sides of the transverse block 8 will respectively apply elastic force to the transverse block 8, so that in the absence of external force, the transverse block 8 will be in the middle position of the transverse groove 7, and when the arc-shaped spring piece 6 drives the transverse block 8 to move, the telescopic spring 11 will accumulate potential energy, and when the external force is lost, it will drive the transverse block 8 and the push rod 12 to return to their original position.
[0046] Combination Figure 3 As shown, a transverse mechanism driven by an arc-shaped spring piece 6 is installed on the side wall of the transverse block 8, and the transverse mechanism includes a push rod 12, a long plate 13 and two staggered axis racks 14. One end of the push rod 12 is fixedly connected to the side wall of the transverse block 8, and the other end is fixedly connected to the side wall of the long plate 13. The push rod 12 is "L"-shaped, and the two arc-shaped spring pieces 6 are respectively fixedly arranged on the side walls at both ends of the transverse block 8. The push rod 12 is fixedly arranged at the center position of the transverse block 8. Since the two side speakers 2 can be rotated, the two arc-shaped spring pieces 6 need to be able to drive the transverse block 8 to move together, so the two arc-shaped spring pieces 6 need to be respectively arranged at both ends of the transverse block 8 to drive the transverse block 8 to move in the transverse groove 7.
[0047] A through slot 15 is provided at the bottom of the central speaker 1, and both ends of the through slot 15 are open. Movement slots 16 are provided at the bottom of the two side speakers 2, and the two movement slots 16 are open at one end facing the through slot 15. The movement slot 16 is connected to the through slot 15, and the long board 13 is slidably connected to the side wall of the through slot 15, so the long board 13 can easily move from the through slot 15 to the movement slot 16, and in the initial state, the long board 13 is located in the through slot 15, and the length of the long board 13 is equivalent to the length of the through slot 15, and the two staggered axis racks 14 are fixedly arranged on the side walls of the long board 13.
[0048] Combination Figure 3 and Figure 4 As shown, two support blocks are installed at the bottom of the center speaker 1 and the side speaker 2, each support block is located between the center speaker 1 and the side speaker 2, the bottom of the support block is against the desktop, the support block includes a top plate 17, two fixed columns 18 and two movable columns 19, the top plate 17 is arranged at the bottom of the center speaker 1 and the side speaker 2, the two fixed columns 18 are respectively fixed at the bottom of the top plate 17, the two movable columns 19 are respectively movably sleeved on the side wall of the fixed column 18 away from the top plate 17, and the top plate 17 arranged at the bottom of the center speaker 1 and the side speaker 2 is from the attached Figure 3 It can be seen from the figure that the arrangement is tilted, and the top plate 17 spanning the two speakers can stably support the two speakers. Even after the side speaker 2 is rotated, the remaining center speaker 1 and the other side speaker 2 can also stay stably in the initial position.
[0049] A groove 20 is provided on the top of the top plate 17, and the position of the groove 20 is consistent with the position of the long plate 13. The arrangement of the groove 20 allows the long plate 13 to easily pass through the position of the top plate 17 when it moves with the push rod 12. A fixing rod 21 is fixedly connected to one end of the top of the top plate 17, and the fixing rod 21 is fixedly connected to the bottom of the center speaker 1 at one end away from the top plate 17. An arc groove 22 is provided on the other end of the top of the top plate 17, and one end of the arc groove 22 is open. A sliding rod 23 is slidably connected in the arc groove 22, and the other end of the sliding rod 23 is fixedly connected to the bottom of the side speaker 2. The arrangement of the sliding rod 23 and the arc groove 22 allows the side speaker 2 to easily leave the position of the top plate 17 when rotating.
[0050] Combination Figure 4 and Figure 5As shown, a cavity is provided on the top of the top plate 17, in which an electric push rod 24 is installed. The electric push rod 24 is electrically connected to the PIR sensor 4, and a clamping rod 25 is fixedly connected to the output end of the electric push rod 24. A clamping groove 26 is provided on the side wall of the sliding rod 23. The clamping rod 25 passes through the side wall of the arc groove 22 and is clamped with the side wall of the clamping groove 26. When the user passes by the PIR sensor 4, the electric push rod 24 will be activated, thereby causing the clamping rod 25 to disengage from the clamping groove 26, thereby facilitating the rotation of the side speaker 2, ensuring that the side speaker 2 can move with the user, thereby ensuring the playback effect of the side speaker 2.
[0051] Combination Figure 6 and Figure 7 As shown, a lifting mechanism is installed in the support block, and the lifting mechanism includes a staggered shaft gear 27, a rotating rod 28, two first bevel gears 29, two second bevel gears 30 and two threaded rods 31. A rotating groove 32 is opened in the groove 20, and the staggered shaft gear 27 is located in the rotating groove 32. A working chamber is opened in the top plate 17, and the rotating rod 28 is rotatably connected to the side wall of the working chamber. The staggered shaft gear 27 is fixedly connected to the side wall of the rotating rod 28, and the staggered shaft gear 27 is meshed with the staggered shaft rack 14. Although the angle between the two is not a standard 90°, since the teeth of the staggered shaft gear 27 are themselves inclined, the staggered shaft gear 27 can still be driven to rotate by the staggered shaft rack 14.
[0052] The two first bevel gears 29 are respectively fixedly arranged on the side walls on both sides of the rotating rod 28, and the bottoms of the two second bevel gears 30 are respectively fixedly connected with blank rods 33, which pass through the side walls of the working chamber, and a bearing 34 is provided at the bottom of the working chamber. The outer side of the bearing 34 is fixedly connected to the side wall of the working chamber, and the inner wall of the bearing 34 is fixedly connected to the side wall of the blank rod 33. The second bevel gear 30 is meshed with the first bevel gear 29, and the end of the blank rod 33 away from the second bevel gear 30 is fixedly connected to the threaded rod 31, and the threaded rod 31 passes through the side wall of the fixed column 18, and a threaded groove 35 is provided on the side wall of the movable column 19, and the threaded rod 31 is threadedly connected to the inner wall of the threaded groove 35. When the long board 13 is driven to move by the pushing rod 12, the staggered axis rack 14 will drive the staggered axis gear 27 to rotate, and then the first bevel gear 29 drives the second bevel gear 30 to rotate, and finally the movable column 19 is raised to a position, so that the other side speaker 2 that does not need to move is combined with the center speaker 1 as a whole, thereby ensuring the overall stability.
[0053] The working principle of this embodiment is as follows: in the initial state, the central speaker 1 and the two side speakers 2 are supported by the support block at the same time. Since the sliding rod 23 is still stuck in the arc groove 22 by the clamping rod 25, the side speakers 2 and the central speaker 1 are still connected and will not rotate easily.
[0054] After placing the speaker in a fixed position, ensure that there is enough space behind the speaker to facilitate the rotation of the side speaker 2;
[0055] Then start the speaker. When the user changes the position, the PIR sensor 4 detects that the user has moved, and will first drive the electric push rod 24 to move, and then move the driving wheel 5. The electric push rod 24 moves the clamping rod 25 toward the inside of the cavity, so that the clamping rod 25 leaves the clamping groove 26, and the position of the sliding rod 23 is no longer restricted by the clamping rod 25. At the same time, the driving wheel 5 will also be driven, so that the side speaker 2 is driven to move. Since the driving wheel 5 is inclined, the side speaker 2 will also rotate around the position where it is hinged with the center speaker 1, so as to move in the direction of the user. After the sliding rod 23 leaves the position of the arc groove 22, the top plate 17 will also play a supporting effect under the support of the fixed column 18 and the movable column 19;
[0056] When the side speaker 2 is in the rotation position, the buffer block 10 will move in the buffer groove 9, thereby delaying the timing of the long board 13 moving, so that when the side speaker 2 is rotated at a small angle, the movable column 19 will not be driven to rise;
[0057] When the side speaker 2 on this side rotates at a larger angle, the buffer block 10 will move to the end of the buffer groove 9. At this time, the arc-shaped spring piece 6 will move with the side speaker 2, thereby pushing the transverse block 8 to move in the transverse groove 7, and the telescopic springs 11 on both sides of the transverse block 8 will rotate together;
[0058] The push rod 12 on the side wall of the transverse block 8 will also drive the long board 13 to move in the corresponding direction. The long board 13 sliding in the through groove 15 will directly move to the motion groove 16 at the bottom of the other side speaker 2. At this time, the staggered axis rack 14 on the side wall of the long board 13 will drive the staggered axis gear 27 to rotate. The rotation of the staggered axis gear 27 will cause the rotating rod 28 to drive the first bevel gear 29 to rotate, and the second bevel gear 30 meshing with it will drive the blank rod 33 to rotate in the bearing 34. The threaded rod 31 at the bottom of the blank rod 33 will cause the movable column 19 to rise along the fixed column 18, so that the side speaker 2 on this side becomes a whole with the center speaker 1, thereby ensuring that the rotating side speaker 2 will not affect the stability of the two speakers.
[0059] The above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention.
