Technical Field

[0001] The utility model relates to the technical field of audio accessories, in particular to an AGPP acoustic waveguide phase plug loudspeaker. Background Art

[0002] AGPP acoustic waveguide phase plug speaker is an advanced audio technology that combines the characteristics of acoustic waveguide and phase plug, combining these two technologies to achieve high-quality sound wave guidance through acoustic waveguide and eliminate phase distortion by using phase plug. This design enables the speaker to present clearer, more realistic and three-dimensional sound quality, bringing an immersive audio experience to users.

[0032] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.

[0033] See also Figure 1-Figure 9 , which shows a schematic diagram of the structure of an AGPP acoustic waveguide phase plug loudspeaker embodiment of the utility model, please refer to Figure 1-Figure 9 , a detailed introduction is given to an AGPP acoustic waveguide phase plug loudspeaker.

[0034] An AGPP acoustic waveguide phase plug loudspeaker comprises a housing 100, the housing 100 is horn-shaped, a ring-shaped annular groove 110 is arranged inside the shell of the housing 100, and the center of the housing 100 coincides with the center of the annular groove 110;

[0035] The inner side wall of the annular groove 110 is rotatably provided with a gear ring 200, and the inner side wall of the annular groove 110 is rotatably provided with follower gears 210 equidistantly arranged around its own ring center, and the teeth of each follower gear 210 are meshed with the teeth of the gear ring 200, and the inner side of each follower gear 210 is threadedly provided with a screw 220;

[0036] A rotating rod 300 is rotatably disposed on the rear side wall of the inner cavity of the annular groove 110 . A driving gear 310 meshing with the gear ring 200 is disposed on the rod body of the rotating rod 300 . A driving device is disposed at the front end of the rotating rod 300 .

[0037] Furthermore, the rear side wall of the housing 100 is located behind the annular groove 110 and is equidistantly provided with screw holes 120 around the center of the annular groove 110. The screw holes 120 correspond to the screws 220 one by one and are threaded through by the screws 220. The speaker is provided with a mounting opening for mounting the housing 100 and a screw hole 2 for aligning the screw hole 120 and the screw 220. The user mounts the speaker on the speaker.

[0038] Furthermore, a screw sleeve 230 is fixedly provided on the inner side of each follower gear 210, and the diameter of the screw sleeve 230 is larger than the width of the gear ring 200. The two ends of the screw sleeve 230 are rotatably set on the front and rear side walls of the inner cavity of the annular groove 110 through the bearing sleeve 240. The shaft of the screw 220 is threadedly connected to the inner side of the screw sleeve 230. The screw 220 is not directly threadedly connected to the inner side of the follower gear 210, but is threadedly connected to the inside of the screw sleeve 230 on the inner side of the follower gear 210. In addition, the screw sleeve 230 is rotated on the inner cavity side wall of the annular groove 110 through the bearing sleeve 240, thereby rotating the follower gear 210 "fixed" in the inner cavity of the annular groove 110.

[0039] Furthermore, the driving device includes a cylindrical sleeve 320 arranged at the front end of the rotating rod 300, and a mounting hole 321 is opened at the front end of the sleeve 320. The front end of the inner wall of the mounting hole 321 is concavely provided with a limiting groove 322 at an equal interval around the sleeve 320 as the center, and the inner cavity side wall of the mounting hole 321 is rotatably provided with an elastic member 340 through the bearing seat 330. The front end of the elastic member 340 is provided with a driving round block 350, and the outer wall of the driving round block 350 is protruded with a limiting strip 351 at an equal interval around the sleeve 320 as the center. The limit strip 351 corresponds to the limit groove 322 one by one and their shapes fit each other. A cylindrical drive cylinder 360 is fixedly provided at the front end of the drive block 350. A second mounting hole 361 is opened at the rear end of the drive cylinder 360. The front end of the drive block 350 is fixed on the side wall of the second mounting hole 361, and the inner side of the second mounting hole 361 is sleeved on the outer side of the sleeve 320. The outer side wall of the drive cylinder 360 slides through the front surface of the shell 100. A knob 370 is provided at the front end of the drive cylinder 360, and the knob 370 is used to conveniently drive the drive cylinder 360 to rotate.

[0040] Furthermore, when the elastic member 340 is not squeezed by the driving cylinder 360, the elastic member 340 pushes the driving block 350 so that the limit strip 351 and the limit groove 322 remain separated. At this time, even if the driving cylinder 360 rotates, the sleeve 320 cannot drive the gear 310 to rotate, thereby avoiding accidentally touching the knob 370 to cause the screw 220 to rotate. When the user pushes the knob 370 to press the limit strip 351 into the limit groove 322, the knob 370 can be rotated to drive the sleeve 320 and the driving gear 310 to rotate.

[0041] During specific use, when the speaker needs to be quickly removed from the installation port of the audio system, the user pushes the knob 370 to press the limit strip 351 into the limit groove 322, and then turns the knob 370 to drive the drive cylinder 360 and the drive block 350 to rotate. That is, it is necessary to apply a thrust to the knob 370 while applying a rotational force so that the sleeve 320 drives the drive gear 310 and the rotating rod 300 to rotate, and then all the follower gears 210 are rotated through the ring gear 200, so that the screw 220 is turned out from the screw hole 2 of the audio system. No tools are required, and there is no need to remove the screws one by one. The speaker can be quickly removed from the installation port of the audio system, which is convenient for use.

[0042] Although the present invention has been described above with reference to the embodiments, various modifications may be made thereto and parts thereof may be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the various features in the embodiments disclosed in the present invention may be used in combination with each other in any manner, and the fact that these combinations are not exhaustively described in this specification is only for the sake of omitting space and saving resources. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
