Description

Technical Field

[0001] The utility model relates to the field of speakers, and particularly relates to a sealed speaker. Background Art

[0002] A speaker is a music playback device, which is widely used in outdoor stages, cinemas, conference halls and other places. However, speakers are usually used outdoors, so speakers need to have good dust and waterproof performance, and the sealing structure of the speaker is an important factor determining the waterproof and dustproof performance of the speaker.

[0003] The Chinese patent discloses a sealed speaker (authorization公告号CN 216391313 U), and this patented technology can solve the problem that the existing closed speakers cannot adjust the angle of the speaker during use, which to a certain extent affects the user experience of the user.

[0004] However, the existing speaker speakers are usually exposed outside. When used outdoors, the speaker part is easily damaged in rainy days, resulting in poor waterproof effect of the speaker. Summary of the Invention

[0005] To solve the above technical problems, the utility model provides a sealed speaker, which includes a bottom plate and a speaker body. A fixing groove is formed on the upper end surface of the bottom plate, a connecting column is installed at the bottom of the fixing groove, a first chuck is installed on the upper end surface of the connecting column, and the speaker body is installed on the upper end surface of the first chuck by a clamping method. Speakers are symmetrically installed on the upper and lower sides of the front end surface of the speaker body, a sealing gasket is arranged on the outer side of the speaker, and a cover cavity is rotatably installed on the front end surface of the speaker body through a pin shaft.

[0006] Preferably: Limiting grooves are symmetrically formed on the left and right sides of the upper end surface of the bottom plate, limiting springs are installed at the inner and outer ends of the limiting grooves, limiting sliders are installed at the other ends of the limiting springs, and limiting plates are installed on the upper end surfaces of the limiting sliders.

[0007] Preferably: C-shaped frames are symmetrically installed on the left and right side walls of the bottom plate, and handles are installed on the upper end surfaces of the C-shaped frames.

[0008] Preferably: A sliding groove is formed on the front end surface of the C-shaped frame, a first spring is installed at the bottom of the sliding groove, a first slider is installed on the upper end surface of the first spring, a connecting frame is installed on the front end surface of the first slider, and a pressing plate is installed at the bottom of the connecting frame.

[0009] Preferably: The bottom of the pressing plate is connected to the upper end surface of the cover cavity by a clamping method.

[0010] Preferably: The cover cavity is connected to the right side wall of the speaker body by a clamping method.

[0011] The technical effects and advantages of the utility model:

[0012] 1. The utility model adopts a cover cavity structure, which can seal and protect the speaker, thereby effectively preventing the failure to timely fold up the speaker body when working outdoors on rainy days, causing rainwater to enter the interior of the sound body through the speaker and cause damage to the internal structure of the device.

[0013] 2. The utility model adopts a pressure plate structure to prevent the cover cavity from being loosened when the speaker body is carried on rainy days, thereby losing the waterproof protection effect on the speaker. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The invention of the present invention is given for the purpose of illustration and description, and is not intended to be exhaustive or to limit the present invention to the disclosed form. Many modifications and variations are obvious to those of ordinary skill in the art. The invention is selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and design various inventions with various modifications suitable for specific purposes.

[0020] See also Figures 1 to 4, in this embodiment, a sealed speaker is provided, which includes a bottom plate 1 and a speaker body 2. A fixing groove is formed on the upper end surface of the bottom plate 1. A connecting column 11 is installed at the bottom of the fixing groove. A first chuck 12 is installed on the upper end surface of the connecting column 11. The speaker body 2 is installed on the upper end surface of the first chuck 12 in a clamping manner. On the front side end surface of the speaker body 2, speakers 13 are symmetrically installed up and down. A sealing gasket 14 is arranged on the outer side end of the speakers 13. A cover cavity 15 is rotatably installed on the front side end surface of the speaker body 2 through a pin shaft. During operation, the sealing gasket 14 structure is adopted to protect the speaker body 2 from dust and water. When it rains, the cover cavity 15 can seal and protect the speakers 13, effectively avoiding the situation that when the speaker body 2 is not timely collected during outdoor work on a rainy day, rainwater enters the interior of the speaker body through the speakers 13, causing damage to the internal structure of the device. The first chuck 12 structure is adopted to facilitate the disassembly and replacement of the speaker body.

[0021] Limit grooves are symmetrically formed on the left and right sides of the upper end surface of the bottom plate 1. A limit spring 16 is installed at the inner and outer ends of the limit groove. The other end of the limit spring 16 is installed with a limit slider. A limit plate 17 is installed on the upper end surface of the limit slider. During operation, the limit spring 16 drives the limit plate 17 to move inwards, thereby clamping and fixing the speaker body 2 to prevent the speaker body 2 from being unstable when placed.

[0022] C-shaped frames 18 are symmetrically installed on the left and right side walls of the bottom plate 1. A handle 19 is installed on the upper end surface of the C-shaped frames 18. During operation, the speaker body 2 can be lifted by hand holding the handle 19, which is convenient for carrying and handling it.

[0023] A sliding groove is formed on the front side end surface of the C-shaped frame 18. A first spring 21 is installed at the bottom of the sliding groove. A first slider is installed on the upper end surface of the first spring 21. A connecting frame 22 is installed on the front side end surface of the first slider. A pressing plate 23 is installed at the bottom of the connecting frame 22. During operation, the first spring 21 drives the pressing plate 23 to press downwards to press and fix the cover cavity 15, avoiding the cover cavity 15 from loosening and losing the waterproof protection effect on the speakers 13 when carrying the speaker body 2 on a rainy day.

[0024] The bottom of the pressing plate 23 is connected to the upper end surface of the cover cavity 15 in a clamping manner. During operation, the clamping method is adopted to ensure the connection effect between the pressing plate 23 and the cover cavity 15, further avoiding the cover cavity 15 from loosening during running.

[0025] The cover cavity 15 is connected to the right side wall of the speaker body 2 in a clamping manner. The clamping method is adopted to facilitate the rotation and opening of the cover cavity 15.

[0026] During specific operation, a sealing gasket 14 structure is used to protect the speaker body 2 from dust and water. When it rains, the cover cavity 15 can seal and protect the speaker 13, thereby effectively avoiding the situation where the speaker body 2 is not put away in time when working outdoors on rainy days, resulting in rainwater entering the interior of the audio body through the speaker 13 and causing damage to the internal structure of the device. The first clamp 12 structure is used to facilitate the disassembly and replacement of the audio body.

[0027] Obviously, the invention described is only a part of the invention of the utility model, not the whole invention. Based on the invention in the utility model, all other inventions obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the utility model. The structures, devices and operating methods not specifically described and explained in the utility model shall be implemented according to the conventional means in the field unless otherwise specified and limited.
