Description

Technical Field

[0001] The invention relates to the field of sound boxes, and in particular to a projector sound box and a projector. Background Art

[0002] A projector for outdoor use is a portable projection device specially designed for outdoor environments. It has some special features that enable it to adapt to outdoor conditions and provide a good viewing experience. It usually has a brightness of more than 3,000 lumens to cope with the interference of natural light. It has a certain degree of waterproof and dustproof capabilities to cope with outdoor environments. It uses durable materials and can withstand a certain degree of collision and vibration. It is usually equipped with multiple interfaces such as HDMI and USB to support the connection of multiple devices. It supports Wi-Fi or Bluetooth connection for easy pairing with smart devices.

[0003] The speakers for outdoor projectors are audio playback devices specially designed for use with outdoor projection equipment. They are usually small in size, lightweight, easy to carry and set up, have a certain degree of waterproofness, and can cope with moisture or light rain. They have built-in rechargeable batteries and provide a long period of use without the need for continuous external power supply. They can provide a loud enough volume to cover open outdoor spaces and support wireless Bluetooth connection for easy pairing with projectors or other devices.

[0004] Existing projector speakers used outdoors are mostly placed on the surface of the projector or on a flat surface for placing the projector, without a separate supporting structure. This is because the speaker itself has a stable base design and can be placed directly on a flat surface. However, in the outdoor environment, the ground is uneven, and tables, chairs and benches are difficult to place stably. The projector needs to carry an additional support frame (similar to the support frame used for cameras in the wild environment) to be placed stably. The position of the speaker is limited by the position of the projector, which affects the sound effect and thus affects the user experience.

[0005] Therefore, it is necessary to propose a projector speaker and a projector to solve the above problems. Summary of the invention

[0017] Beneficial Effects

[0018] Compared with the prior art, the present invention provides a projector speaker and a projector, which have the following beneficial effects:

[0019] 1. The projector speaker, through the support column and the circular groove, the support spring is compressed, which can support the speaker body. First, the two L-shaped columns are adjusted to rotate respectively, and the two L-shaped columns form a cross, and then the two adjustment blocks are adjusted to rotate. The studs are connected to the support plate by threads. The rotation of the studs can drive the arc-shaped limit block to approach the annular rack until it cooperates with the annular rack to limit the rotation of the cylinder, thereby ensuring the stability of the L-shaped column after the angle is adjusted. Then, according to the ground conditions of the actual placement position, the relative movement between the L-shaped column and the oblique groove is adjusted to ensure that the speaker body can be placed stably and is no longer restricted by the position of the projector. The speaker body can be away from the ground to avoid affecting the sound effect, thereby ensuring the user experience.

[0020] 2. The projector speaker, through the cleaning mechanism, during the process of adjusting the angle of the L-shaped column, the inclined column rotates with the L-shaped column, the inclined column contacts the surface of the connecting rod, the connecting rod rotates with the rotation of the inclined column, the connecting rod rotating column rotates with the rotation of the connecting rod, the spiral groove on the surface of the rotating column can produce relative sliding with the protrusion, and then can drive the mounting frame to move, and the cleaning brush on the surface of the mounting frame can clean the dust on the surface of the dustproof net, that is, the dust on the surface of the dustproof net is cleaned at the same time during the placement of the speaker body, to ensure that the sound effect of the speaker remains clear, thereby ensuring the user experience.

[0021] 3. The projector speaker utilizes the elastic force of the supporting spring to enable the speaker body to be in close contact with the surface of the rotating block. The rotating block limits the installation of the speaker body, thereby ensuring that the speaker body and the projector are stably installed. Multiple L-shaped support columns can support the projector to keep the projector away from the ground. In the field, the L-shaped columns can be adjusted to move to adapt to stable placement on uneven ground surfaces. That is, the speaker body can not only be used in conjunction with the projector to support the projector, but can also be used alone. Users can flexibly choose the usage method, thereby enhancing the applicability of the equipment. BRIEF DESCRIPTION OF THE DRAWINGS

An inclined column 3210 is symmetrically arranged in the rectangular hole 13, and the inclined column 3210 is installed in cooperation with the connecting rod 27. An inclined groove 3211 is opened in the inclined column 3210, and an L-shaped column 3212 is slidably connected to the groove wall of the inclined groove 3211. The L-shaped column 3212 is installed in cooperation with the friction plate 329. An annular rack 3213 is fixedly connected to the surface of the cylinder 325, and a stud 3214 is arranged above the annular rack 3213. Both studs 3214 are connected to the support plate 314 by threads, and the upper end of the stud 3214 is fixedly connected to an adjustment block 3215, and the lower end of the stud 3214 is fixedly connected to an arc-shaped limit block 3216;

[0043] It should be noted that the adjustment component 32 can play an adjustment role so that the speaker body 11 and the housing 1 can be placed stably on uneven ground in the wild;

[0044] In the field, the speaker body 11 and the housing 1 can be used separately or in combination according to the needs of the user. When the speaker body 11 is used alone, the two inclined columns 3210 and the L-shaped column 3212 are rotated and adjusted, and the T-shaped column 327 is fixedly connected to the inclined column 3210. The T-shaped column 327 rotates with the rotation of the inclined column 3210, thereby driving the cylinder 325 to rotate. The rotation of the cylinder 325 drives the first gear 324 and the annular rack 3213 to rotate. The first gear 324 is meshed with the rack column 321, thereby driving The movable rack column 321 moves, the first spring 322 is stretched, the rotation adjustment block 3215 drives the stud 3214 to rotate, the stud 3214 is threadedly connected with the support plate 314, and the arc-shaped limit block 3216 cooperates with the annular rack 3213 to limit the position of the cylinder 325 after rotation adjustment, that is, the two L-shaped columns 3212 and the inclined column 3210 are limited after adjustment. According to the ground conditions of the actual placement location, the L-shaped column 3212 is adjusted to move, so that the speaker body 11 can be stably placed on an uneven ground and separated from the ground;

[0045] When the speaker body 11 is used in conjunction with the housing 1, the speaker body 11 is moved from top to bottom, and the two L-shaped columns 3212 are inserted into the rectangular hole 13 until the trapezoidal groove 3217 on the surface of the movable block 323 contacts the surface of the trapezoidal block 3218 and generates relative sliding, thereby driving the rack column 321 to move, and the first gear 324 rotates as the rack column 321 moves, thereby driving the cylinder 325 to rotate, and the T-shaped column 327 rotates as the cylinder 325 rotates, and the oblique column 3210 and the L-shaped column 3212 rotate as the T-shaped column 327 rotates, and the two oblique columns 3210 turn in opposite directions to form a cross, and the support spring is used to rotate. Due to the elastic force of 312, when the movable block 323 contacts the bottom of the concave part of the surface of the shell 1, the rotating block 12 can limit the installation of the speaker body 11. After the speaker body 11 is limited in installation, the two L-shaped columns 3212 can be limited in rotation, and then the movement of the L-shaped columns 3212 can be adjusted according to the ground conditions of the actual placement to adapt to stable placement on an uneven ground surface. That is, the speaker body 11 can not only be used in conjunction with the projector to support the projector, but also can be used alone. The user can flexibly choose the usage method, which enhances the applicability of the equipment and ensures the user experience.

[0046] It should be noted that the support plate 314 and the support column 311 are separable, and the support plate 314, the L-shaped column 3212 and the inclined column 3210 can be used separately, and the inclined column 3210 can contact the edge of the surface of the rectangular hole 13 to form support for the housing 1;

[0047] It should be noted that a sleeve can be sleeved on the surface of the L-shaped column 3212, and the speaker body 11 can be installed in the recessed part diagonally arranged on the surface of the outer shell 1, both of which can support the outer shell 1. By adjusting the movement of the sleeve, the overall supporting range is increased, which can ensure that the outer shell 1 is placed stably. That is, only two of the four speaker bodies 11 need to cooperate with the recessed parts on the surface of the outer shell 1, and the other two speaker bodies 11 can be used separately. Users can configure them according to actual needs to enhance the audio effect and ensure better sound propagation.

[0048] See also Fig.10 , the initial state of the second spring 328 is a compressed state;

[0049] It should be noted that the reaction force generated by the compression of the second spring 328 acts on the surface of the T-shaped column 327, so that the inclined column 3210 can be in close contact with the recessed part of the surface of the outer shell 1, and the friction plate 329 can be in close contact with the inclined column 3210, thereby increasing the friction force, and being able to support the outer shell 1, thereby ensuring the stability of the L-shaped column 3212 after position adjustment, that is, ensuring the stable placement of the projector.

[0050] See also Fig. 9 A trapezoidal groove 3217 is provided on the surface of the movable block 323, and a trapezoidal block 3218 is symmetrically fixedly connected to the surface of the housing 1 beside the rectangular hole 13, and the trapezoidal groove 3217 is slidably connected to the trapezoidal block 3218;

[0051] It should be noted that when the speaker body 11 is matched with the concave part of the surface of the shell 1, the speaker body 11 is from top to bottom, the L-shaped column 3212 and the inclined column 3210 gradually pass through the rectangular hole 13, the trapezoidal groove 3217 contacts the surface of the trapezoidal block 3218, and relatively slides until the surface of the movable block 323 contacts the bottom of the concave part of the surface of the shell 1, the first spring 322 is stretched, and the rack column 321 moves with the movement of the movable block 323, thereby driving the first gear 324 and the cylinder 325 to rotate, thereby driving the inclined column 3210 and the L-shaped column 3212 to rotate, that is, during the process of matching and installing the speaker body 11 with the shell 1, the rotation adjustment of the L-shaped column 3212 is completed at the same time, the shell 1 is supported, and the placement steps of the projector are optimized;

[0052] It should be noted that the housing 1 is an existing projector mounting housing 1 .
