Description

Technical Field

[0001] The utility model relates to the technical field of audio, in particular to a sound system with an adjustable sound transmission range. Background Art

[0002] Audio refers specifically to an audio system that produces sound through a combination of electrical equipment. The development history of audio technology can be divided into four stages: electron tubes, transistors, integrated circuits, and field effect transistors.

[0003] An important device in the sound system is the speaker, which is generally composed of a speaker unit and a cabinet. The speaker unit is the sound-generating component, and the cabinet complements the speaker unit and plays the role of correcting the sound. The sound-generating principle of the speaker unit is a conversion of electrical energy into sound. When different electron energies are transmitted to the coil, the coil generates a kind of energy that interacts with the magnetic field of the magnet. This interaction causes the paper plate to vibrate. Because the electron energy changes at any time, the speaker coil will move forward or backward, so the speaker paper plate will move with it. These actions change the density of the air and produce sound.

[0004] The existing technology has the following problems:

[0005] In actual use, existing speakers can only adjust the volume to control the sound volume, while the transmission range of the speakers is often inconvenient and cannot be changed according to the size of the venue, which is not conducive to users to better experience the sound effects of the speakers. Utility Model Content

[0009] Preferably, the bottom end of the hinged seat 1 is fixedly mounted to the outside of the limiting ring.

[0010] Preferably, the limiting block matches the limiting groove and can slide in a limiting manner.

DETAILED DESCRIPTION

[0024] The present invention is further described in detail below in conjunction with the embodiments:

[0025] like Figure 1-5 As shown, the utility model provides a speaker with an adjustable sound transmission range, comprising a support column 1, a support assembly 2 is installed at the lower end of the support column 1, a movable rod 3 is movably installed inside the support column 1, a mounting plate 4 is fixedly installed on the top of the movable rod 3, a speaker 5 is fixedly installed on the upper end of the mounting plate 4, a sound hole 6 is opened on the front side of the speaker 5 board, adjustment mechanisms 7 are symmetrically installed on both sides of the sound hole 6, a through hole 8 is opened on the top front side of the support column 1, an adjusting bolt 9 is movably inserted inside the through hole 8, and a plurality of groups of screw holes 10 are equidistantly distributed on the surface of the movable rod 3.

[0026] The adjusting bolt 9 is threadedly connected with the screw hole 10 .

[0027] By loosening and removing the adjusting bolt 9 from the screw hole 10, the movable rod 3 can be adjusted up and down, and the speaker 5 can be raised to a higher distance from the ground, so that the sound of the speaker can be better diffused, greatly improving the efficiency and performance of the speaker. Then the adjusting bolt 9 can be inserted into the screw hole 10 through the through hole 8 and tightened, so as to limit the movable rod 3 and make it difficult to move.

[0028] like Figure 3-4 As shown, the support assembly 2 includes a limit ring 21, the interior of the limit ring 21 is fixedly sleeved with the exterior of the lower end of the support column 1, three groups of hinged seats 22 are equidistantly distributed on the outside of the limit ring 21, the inner side of the hinged seat 22 is rotatably connected with a mounting seat 23, a support plate 24 is fixedly installed at the front end of the mounting seat 23, a bottom plate 25 is fixedly installed at the bottom of the support plate 24, three groups of fixed hinged seats 26 26 are equidistantly distributed on the outer side of the bottom of the support column 1, the inner side of the hinged seat 26 is rotatably connected with a connecting plate 27, a limit groove 28 is provided on the inner side of the support plate 24, the top of the connecting plate 27 is rotatably connected with a hinged seat 3 211, the bottom of the hinged seat 3 211 is fixedly installed with a connecting plate 210, and a limit block 29 is fixedly installed at the bottom of the connecting plate 210.

[0029] The bottom end of the hinged seat 22 is fixedly mounted on the outside of the limiting ring 21 .

[0030] The limiting block 29 matches the limiting groove 28 and can slide in a limited manner.

[0031] The hinged seat 1 22 , the hinged seat 26 and the hinged seat 3 211 can be conveniently installed to rotate and adjust the seat 23 , the support plate 24 and the connecting plate 27 .

[0032] like Figure 5 As shown, the adjustment mechanism 7 includes two groups of guide grooves 71, and the two groups of guide grooves 71 are symmetrically arranged on both sides of the front of the speaker 5. The internal limiting sliding of the guide groove 71 is provided with a guide block 72, the front end of the guide block 72 is installed with a side panel 73, the middle part of the side panel 73 is fixedly installed with a sound sealing plate 74, and the front of the sound sealing plate 74 is fixedly installed with a handle 75.

[0033] The front end of the guide block 72 and the rear end of the side plate 73 are symmetrically fixedly installed.

[0034] The sound sealing plate 74 is arc-shaped.

[0035] The guide block 72 and the guide groove 71 are provided to facilitate the movement of the sound sealing plate 74 , and the arc-shaped sound sealing plate 74 facilitates the shielding of the sound outlet 6 .

[0036] The working principle of the speaker with adjustable sound transmission range will be described in detail below.

[0037] like Figure 1-5As shown, when the sound transmission range adjustable speaker is in use, the three groups of support plates 24 can be pulled outward first, so that the support plates 24 drive the mounting seat 23 to rotate on the inner side of the hinge seat 1 22, thereby facilitating the rotation of the support plates 24. When the support plates 24 rotate outward, the connecting plates 27 drive the limit blocks 29 to slide downward in the limit grooves 28 through the hinge seat 3 211 and the connecting plates 210, thereby limiting the rotation angle of the support plates 24, thereby making the bottom plate 25 contact with the ground, thereby improving the stability of the support column 1, making it difficult for the speaker 5 to be used. and when the sound transmission range of the speaker 5 needs to be adjusted, the two sets of handles 75 can be pulled inward, so that the handles 75 drive the sound sealing plates 74 to move synchronously, and the sound sealing plates 74 drive the guide blocks 72 to move synchronously in the guide grooves 71 through the side plates 73, so that the two sets of sound sealing plates 74 can be gradually brought closer, and then the sound sealing plates 74 can be used to block the sound outlet holes 6 on the speaker 5, so that the sound transmission of the speaker 5 can be more concentrated, and when the sound sealing plates 74 move to both sides, the sound range of the speaker 5 will be expanded, thereby improving the use effect of the speaker 5.

[0038] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
