Description

Technical Field

[0001] The invention relates to the technical field of wall-mounted speakers, in particular to a novel wall-mounted Bluetooth speaker. Background Art

[0002] Wall-mounted Bluetooth speakers are an audio device that combines Bluetooth technology and wall-mounted design. With its advantages of wireless connection, space saving, excellent sound quality and strong decorativeness, it is favored by more and more consumers and is widely used in home environments, commercial places and public places.

[0003] Existing wall-mounted speakers are generally hung on the wall by fixings, and the position of the speakers is fixed and cannot be adjusted according to actual needs. For example, when used in larger venues or other crowded occasions, the position of the speakers needs to be adjusted according to the number of people and their distribution. However, since the existing speakers are generally fixedly installed, it is inconvenient to adjust. Specifically, when there are fewer people in the room, the minority of people generally sit in the front row of the room. At this time, we need the sound output position of the speakers to be concentrated, and do not need the sound to be spread to a farther range. Therefore, the volume of the speakers can be appropriately reduced, and the speakers can be placed low, so as to improve the experience of the front row personnel; and when there are more people in the room, the personnel are generally scattered in various positions in the room. At this time, we need the sound to be spread to a farther position, so it is necessary to appropriately increase the volume and place the speakers high to ensure that the back row personnel can hear the sound and avoid the front row personnel from feeling uncomfortable due to excessive volume. Although the existing speakers can adjust the volume, they cannot adjust the position of the speakers, nor can they change the sound output range, and thus cannot be adjusted according to the number and distribution of people in the room.

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] See also Figure 1- Figure 7 A new type of wall-mounted Bluetooth speaker includes a mounting frame 1, a mounting seat 2 and a speaker body 3. The mounting frame 1 is a long strip structure. Both the mounting frame 1 and the mounting seat 2 are provided with threaded holes for bolts to be inserted. The mounting frame 1 is distributed vertically and fixedly installed on the wall by bolts. The speaker body 3 is fixedly installed on the mounting seat 2 by bolts.

[0032] Furthermore, racks 101 are provided on the left and right inner side walls of the mounting frame 1 in the vertical direction. A linear slide 4 is fixedly installed in the mounting frame 1 in the vertical direction. A connecting plate 5 is fixedly provided on the slide seat of the linear slide 4. The connecting plate 5 is an L-shaped plate structure composed of a vertical plate 501 and a horizontal plate 502. The connecting plate 5 can slide up and down with the slide seat of the linear slide 4. The mounting seat 2 is rotatably connected to the horizontal plate 502 through a hinge seat. The hinge seat is fixedly installed on the upper surface of the horizontal plate 502 near the front side. The bottom of the mounting seat 2 is hinged on the hinge seat so that the mounting seat 2 can be flipped on the connecting plate 5, thereby changing the pitch angle of the mounting seat 2.

[0033] In order to enable the pitch angles of the mounting base 2 and the speaker body 3 to change with the height of the mounting base 2 and the speaker body 3, a transmission assembly 6 is further provided on the vertical plate 501 in this embodiment, the input end of the transmission assembly 6 is meshed with the rack 101, and the output end of the transmission assembly 6 is coaxially connected to the hinge shaft of the hinge base. At the same time, the hinge shaft is located between the two racks 101 and is perpendicular to the rack 101; when the connecting plate 5 slides upward, the mounting base 2 and the speaker body 3 will tilt and rotate downward.

[0034] Specifically, the transmission assembly 6 includes a first gear 601, a worm 602 and a worm wheel 603. The first gear 601 is meshed with the rack 101 on one side of the mounting frame 1. The first gear 601 and the worm 602 are coaxially connected. The rotating shafts of the first gear 601 and the worm 602 are rotatably connected to the vertical plate 501, so that when the first gear 601 rotates, the worm 602 is driven to rotate together. The worm 602 and the worm wheel 603 are meshed, and the worm wheel 603 is coaxially connected with the hinge shaft of the hinge seat on the connecting plate 5, so that the worm wheel 603 is driven to rotate by the worm 602, thereby driving the mounting seat 2 to rotate together.

[0035] In order to make the pitch angle change method of the speaker body 3 more specific, the following description is made: when the connecting plate 5 slides upward with the slide seat of the linear slide 4, the rack 101 on the mounting frame 1 will drive the first gear 601 to rotate, and the first gear 601 will drive the worm 602 to rotate in the same direction, and the worm 602 drives the worm wheel 603 to rotate, thereby driving the hinge shaft on the connecting plate 5 to rotate in the same direction, further increasing the top view angle of the speaker body 3 on the connecting plate 5, so that when the position of the speaker body 3 is changed, the sound expansion hole is always facing the user.

[0036] It should be noted that when there are fewer people in the room, the speaker body 3 can be placed at a lower position and the volume of the speaker can be appropriately reduced; when there are more people in the room, the speaker body 3 can be placed at a higher position and the volume of the speaker can be appropriately increased. It is worth noting that when the speaker position is raised, the speaker body 3 can be tilted and rotated downward, so that the sound output surface is always facing the user, improving the user's auditory experience.

[0037] In order to achieve a better sound amplification effect of the speaker, in the present application, sub-speakers 301 are provided on both sides of the left and right sides of the speaker main body 3, and the sub-speakers 301 and the speaker main body 3 are slidably connected in the horizontal direction. Drive components 7 are provided on both sides of the left and right sides of the speaker main body 3, and the two drive components 7 correspond one by one to the two sub-speakers 301 respectively, so that the drive components 7 can drive the corresponding sub-speakers 301 away from or close to the speaker main body 3.

[0038] Specifically, the left and right side walls of the speaker body 3 are provided with accommodating cavities 304, and the two accommodating cavities 304 correspond to the two sub-speakers 301 one by one, and one end of the sub-speaker 301 is movably embedded in the corresponding accommodating cavity 304, so that when the sub-speaker 301 is close to the speaker body 3, one end will enter the accommodating cavity 304, thereby reducing the overall floor space. The driving assembly 7 includes two scissor assemblies 701, and the two sides of the scissor assemblies 701 are respectively arranged on the inner wall of the accommodating cavity 304 and the side wall of the sub-speaker 301, so that when the sub-speaker 301 is away from or close to the speaker body 3, the scissor assemblies 701 will extend or contract accordingly, thereby making the movement of the sub-speaker 301 more stable.

[0039] In addition, the driving assembly 7 also includes a slider 702, which is slidably connected to the inner wall of the accommodating cavity 304 along the vertical direction, and one end of the scissors assembly 701 sliding on the speaker body 3 is rotatably connected to the slider 702. The left and right inner cavities of the speaker body 3 are both rotatable along the sliding direction of the slider 702 and are provided with a screw rod 703. The slider 702 and the screw rod 703 are threadedly connected so that when the screw rod 703 rotates, it will drive the slider 702 to slide on the inner wall of the accommodating cavity 304 along the vertical direction, thereby driving the sliding end of the scissors assembly 701 to slide, thereby changing the length of the scissors assembly 701.

[0040] Furthermore, the bottom of the two screw rods 703 are both equipped with a first bevel gear 704, and the inner wall of the accommodating chamber 304 is rotatably connected with a second bevel gear 705, and the second bevel gear 705 is meshed with the first bevel gear 704, so that when the second bevel gear 705 rotates, the first bevel gear 704 will be driven to rotate. The ends of the rotating shafts of the two second bevel gears 705 extending to the outside of the speaker body 3 are both provided with a connecting assembly 9, and the other ends of the two connecting assemblies 9 are respectively fixedly connected with second gears 706, and the two second gears 706 are respectively meshed with two racks 101, so that when the rack 101 drives the second gear 706 to rotate, the second gear 706 will drive the second bevel gear 705 to rotate, thereby driving the screw rod 703 and the first bevel gear 704 to rotate. Specifically, when the second gear 706 rolls upward along the rack 101, the two auxiliary speakers 301 move toward the side away from the speaker body 3.

[0041] Specifically, when the connecting plate 5 rises, the second gear 706 on the outside will start to rotate under the action of the rack 101, and the second gear 706 will drive the coaxially connected second bevel gear 705 to rotate, and the second bevel gear 705 will drive the meshing first bevel gear 704 to rotate, and the first bevel gear 704 drives the screw rod 703 to rotate, so that the slider 702 will start to move downward from the top of the screw rod 703, and then drive the sliding end of the scissors assembly 701 to move downward, and the scissors assembly 701 will gradually extend to both sides, further moving the auxiliary speakers 301 on both sides away from the accommodating cavity 304, so that when the speaker body 3 is located at a high place, the sound can diffuse and propagate over a wider range, thereby improving the sound amplification effect.

[0042] In order to make the opening method of the auxiliary speaker 301 more humane, the present application also sets the connecting component 9 into a multi-section structure, and the connecting component 9 includes a telescopic rod 901, and the telescopic rod 901 is formed by two tubular structures connected to each other, and the length of the telescopic rod 901 can be freely extended, but the two ends cannot produce relative torsion; the second bevel gear 705 is fixedly connected to one end of the telescopic rod 901, and the other end of the telescopic rod 901 is fixedly provided with a universal joint 902, and the end of the universal joint 902 away from the telescopic rod 901 is connected to the first connecting rod 90 3. An inner gear ring 909 is provided at one end of the first connecting rod 903 away from the universal joint 902, a third gear 910 is provided inside the inner gear ring 909, a second connecting rod 904 is provided at one end of the third gear 910 facing away from the universal joint 902, a third connecting rod 905 is provided on the outer movable sleeve of the second connecting rod 904, and the second gear 706 is fixedly sleeved on the third connecting rod 905; two anti-slip plates 503 are provided on the upper surface of the horizontal plate 502, and the first connecting rod 903 and the third connecting rod 905 are rotatably connected to the two anti-slip plates 503 respectively. The purpose of designing the universal joint 902 and the telescopic rod 901 is to enable the first connecting rod 903 to always drive the second bevel gear 705 to rotate when the speaker body 3 rotates around the hinge seat.

[0043] A circular groove 906 is provided on the side of the third connecting rod 905 facing the second connecting rod 904, and an electromagnet 907 and a spring 908 are fixedly provided in the circular groove 906. The spring 908 is sleeved on the outside of the electromagnet 907, and one end of the second connecting rod 904 extends into the circular groove 906. The two ends of the spring 908 are respectively fixedly connected to the inner wall of the circular groove 906 and the second connecting rod 904; the second connecting rod 904 is made of iron material. When the electromagnet 907 is energized, the second connecting rod 904 fits the electromagnet 907, the spring 908 is in a compressed state, and the third gear 910 is located on the outside of the inner gear ring 909. When the electromagnet 907 is powered off, the third gear 910 is meshed with the inner gear ring 909. It is worth mentioning that when the electromagnet 907 is powered off, under the thrust of the spring 908, the third gear 910 will approach the inner gear ring 909 and fit therewith. As the third gear 910 rotates, when the teeth of the third gear 910 are aligned with the tooth grooves on the inner gear ring 909, the third gear 910 can be smoothly embedded in the inner gear ring 909.

[0044] In addition, circularly arranged protrusions are provided on the side of the second connecting rod 904, and grooves corresponding to the protrusions are opened on the inner wall of the circular groove 906. The protrusions on the second connecting rod 904 are slidably connected to the grooves in the circular groove 906, so that the third connecting rod 905 can always drive the second connecting rod 904 to rotate synchronously.

[0045] It is worth mentioning that the on and off of the electromagnet 907 is controlled by an external controller. When the electromagnet 907 is powered on, the two auxiliary speakers 301 can remain stationary as the speaker body 3 rises; when the electromagnet 907 is powered off, the two auxiliary speakers 301 can extend to both sides as the speaker body 3 rises. Therefore, the user can control whether the two auxiliary speakers 301 extend and the extension length of the auxiliary speakers 301 according to actual needs.

[0046] Furthermore, a threading bellows 8 is fixedly provided between the left and right auxiliary speakers 301 and the speaker body 3; when the auxiliary speaker 301 moves to the inner cavity of the speaker body 3, the threading bellows 8 is in a contracted state, and the speaker body 3 and the auxiliary speaker 301 have devices such as speakers and crossovers inside. The wires pass through the threading bellows 8 to connect the internal devices of the speaker body 3 and the auxiliary speaker 301, so as to avoid the clutter of wires hindering the movement of the driving component 7.

[0047] A mid-bass amplification unit 302 is provided on the front surface of the speaker body 3, and a tweeter amplification unit 303 is provided on the front surface of the auxiliary speaker 301. The tweeter amplification unit 303 is always located outside the accommodating cavity 304. When the sound is transmitted to the crossover in the speaker body 3, the crossover will divide the full-band sound signal into different frequency bands such as treble, midrange, and bass, and send them to the corresponding speaker units for playback, so as to achieve a better amplification effect.

[0048] The working principle and use process of the present invention are as follows: first, when there are fewer people in the venue and most of them sit in the front row, the linear slide 4 can be used to control the slide seat to move downward, driving the connecting plate 5 to move to the lowest position. At this time, the speaker body 3 and the auxiliary speaker 301 are both in a vertical state, so that the mid-bass sound amplification unit 302 and the tweeter sound amplification unit 303 can face the user. At the same time, one end of the auxiliary speakers 301 on both sides will shrink into the accommodating cavity 304, thereby reducing the overall footprint and avoiding obstruction to low-lying objects or people.

[0049] When there are many people in the venue, and they are scattered in all directions of the venue, it is necessary to raise the position of the speaker to make the sound propagation range wider. The slide seat is controlled by the linear slide 4 to start sliding upward. At this time, the connecting plate 5 will drive the transmission component 6 on the connecting plate 5 to rise synchronously, and the first gear 601 starts to rotate under the action of the rack 101, and the first gear 601 drives the worm 602 to rotate, and the worm 602 drives the worm wheel 603 to rotate a certain angle. As the height of the connecting plate 5 becomes higher and higher, the rotation angle of the worm wheel 603 will also increase, thereby driving the hinge shaft of the hinge seat on the connecting plate 5 to rotate, and further causing the mounting seat 2 to tilt downward and rotate, and the mounting seat 2 will drive the speaker body 3 and the auxiliary speaker 301 to tilt downward and rotate, and as the height increases, the inclination angle of the speaker body 3 and the auxiliary speaker 301 will also increase, so that the mid-bass sound expansion unit 302 and the tweeter sound expansion unit 303 are always facing the user.

[0050] At the same time, as the speaker body 3 rises, the second gear 706 rotatably connected to the outside of the speaker body 3 will rotate under the action of the rack 101, and the second gear 706 drives the coaxially connected second bevel gear 705 to rotate, and the second bevel gear 705 drives the first bevel gear 704 in the accommodating chamber 304 to rotate, and the first bevel gear 704 drives the screw rod 703 to rotate, and the screw rod 703 drives the slider 702 spirally connected at the top to slide downward along the inner wall of the accommodating chamber 304, and the slider 702 will move the sliding end of the scissors fork assembly 701 downward, so that the scissors fork assembly 701 begins to expand outward, and then drives the two auxiliary speakers 301 to move outward. As the height increases, the distance moved by the auxiliary speaker 301 will be farther, so that the tweeter sound expansion unit 303 can cover a wider range, and the sound emitted by the speaker can spread over a wider range, thereby improving the sound expansion effect.

[0051] In addition, when the user wants to change the height of the speaker body 3 but does not want the auxiliary speaker 301 to expand to both sides, the electromagnet 907 can be energized so that the electromagnet 907 absorbs the second connecting rod 904 into the circular groove 906, thereby making the second connecting rod 904 move away from the first connecting rod 903, and then the gear on the second connecting rod 904 disengages from the gear sleeve on the first connecting rod 903. At this time, the third connecting rod 905 and the second connecting rod 904 rotate synchronously, while the second connecting rod 904 will not drive the first connecting rod 903 to rotate, thereby not driving the universal joint 902, the telescopic rod 901, and the second bevel gear 705 to rotate, thereby preventing the screw rod 703 from rotating and the slider 702 from sliding, thereby finally achieving the effect of adjusting the expansion width of the auxiliary speaker 301 according to user needs, which is more flexible to use.
