Description

Technical Field

[0001] The present invention relates to the technical field of loudspeakers, and in particular to a home theater embedded loudspeaker. Background Art

[0002] In the past, after the installation of home theater speakers, their positions and distances were basically fixed. This resulted in the inability to optimize the distribution of sound energy according to actual conditions in home theater spaces of different sizes and layouts. For example, in a larger viewing room, since the distance between speakers cannot be changed, the sound cannot be effectively concentrated in the specific area where the audience is located, resulting in a low sound pressure level, making it difficult for the audience to feel strong and clear sound effects.

[0003] Moreover, the fixed speaker layout also limits the presentation of stereo effects. The sound separation in the left and right directions is not obvious enough, and the sense of hierarchy is missing. It is difficult for the audience to accurately distinguish the source direction of different sound elements in movies or music, and they cannot immerse themselves in a realistic three-dimensional sound field, which greatly affects the overall listening experience.

[0004] In the past, speaker designs did not take into account the need to automatically adjust the sound angle according to the usage scenario. In a complex home theater acoustic environment, the sound may be affected by reflection and refraction from obstacles such as walls and furniture during propagation, resulting in large differences in the sound effects received by audiences in different locations.

[0005] Due to the lack of an automatic angle adjustment mechanism, the speaker cannot optimize the sound propagation direction according to its relative position to the surrounding environment, resulting in uneven sound coverage. The sound may be too strong or too weak in some areas, which seriously affects the consistency and balance of the overall sound effect and reduces the practicality and adaptability of the home theater system. Summary of the invention

[0006] The object of the present invention is to provide a home theater embedded speaker to solve the problems raised in the above background technology.

[0007] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0008] A home theater embedded speaker comprises a mounting frame, a first speaker and a second speaker, wherein the top of the mounting frame is rotatably connected to a bidirectional threaded rod through a mounting seat, and one end of the bidirectional threaded rod is fixedly connected to a driving motor;

[0009] The outer wall of the bidirectional threaded rod is threadedly connected with a slider, the bottom end of the slider is fixedly connected with an axle seat, the bottom end of the axle seat is rotatably connected with a receiving plate, and the bottom surface of the receiving plate is fixedly connected with the top of the speaker;

[0010] A guide slot is provided at the top of the mounting bracket, and the inner wall of the guide slot is slidably connected to the outer wall of the slider near the bottom end. The inner wall of the mounting bracket is fixedly connected to an orientation adjustment component 1, and the speaker 1 and the speaker 2 are symmetrically distributed on both sides of the orientation adjustment component 1. The inner walls of the mounting bracket near both ends are fixedly connected to an orientation adjustment component 2.

[0011] A further improvement of the technical solution of the present invention is that the orientation adjustment component includes a positioning arc disk, the positioning arc disk is fixedly connected to the inner wall of the mounting frame, the outer wall of the positioning arc disk is rotatably connected to a plurality of guide rollers, and the plurality of guide rollers are equidistantly arranged along the arc surface of the positioning arc disk.

[0012] A further improvement of the technical solution of the present invention is that: the bottom end of the sliding block is fixedly connected to a toggle column, the outer wall of the toggle column close to the bottom end is fixedly connected to a return spring, the end of the return spring away from the toggle column is fixedly connected to a positioning block, and the bottom end of the positioning block is fixedly connected to the bottom surface of the inner wall of the receiving plate.

[0013] A further improvement of the technical solution of the present invention is that a dustproof cover is fixedly connected to the top of the mounting frame.

[0014] A further improvement of the technical solution of the present invention is that: the bottom surface of the speaker 1 is fixedly connected with a universal wheel.

[0015] A further improvement of the technical solution of the present invention is that the outer wall of the guide roller is sleeved with a rubber sleeve.

[0016] Due to the adoption of the above technical solution, the present invention has the following technical advances compared with the prior art:

[0017] 1. The present invention provides a home theater embedded speaker, which uses a driving motor and a bidirectional threaded rod to make the first and second speakers close to or away from each other.

[0030] A guide slot 7 is provided at the top of the mounting frame 1, and the inner wall of the guide slot 7 is slidably connected to the outer wall of the slider 8 near the bottom end. The inner wall of the mounting frame 1 is fixedly connected to a direction adjustment component 4, and the speakers 1 2 and 2 3 are symmetrically distributed on both sides of the direction adjustment component 4. The inner walls of the mounting frame 1 near both ends are fixedly connected to direction adjustment components 2 5.

[0031] Example 2

[0032] like Figure 1-5 As shown, based on Example 1, the present invention provides a technical solution: preferably, the orientation adjustment component 4 includes a positioning arc disk 15, the positioning arc disk 15 is fixedly connected to the inner wall of the mounting frame 1, and the outer wall of the positioning arc disk 15 is rotatably connected to a plurality of guide rollers 16, and the plurality of guide rollers 16 are equidistantly arranged along the arc surface of the positioning arc disk 15.

[0033] The bottom end of the slider 8 is fixedly connected to a toggle column 12, the outer wall of the toggle column 12 near the bottom end is fixedly connected to a return spring 13, the end of the return spring 13 away from the toggle column 12 is fixedly connected to a positioning block 14, and the bottom end of the positioning block 14 is fixedly connected to the bottom surface of the inner wall of the receiving plate 11.

[0034] A dustproof cover 18 is fixedly connected to the top of the mounting frame 1 .

[0035] The bottom surface of the speaker 2 is fixedly connected with a universal wheel 17.

[0036] The outer wall of the guide roller 16 is sleeved with a rubber sleeve.

[0037] Let's talk about the working principle of this home theater embedded speaker in detail.

[0038] like Figure 1-5 As shown, the mounting bracket 1 is embedded in the wall of the home theater, and can store the speaker 1 2 and the speaker 2 3 while preventing dust.

[0039] When needed, the distance between the speaker 1 2 and the speaker 2 3 can be adjusted according to the use requirements. The driving motor 9 is powered on to start the driving motor 9, so that it drives the bidirectional threaded rod 6 to rotate, and the bidirectional threaded rod 6 drives the speaker 1 2 and the speaker 2 3 to approach each other through the corresponding slider 8. When the bidirectional threaded rod 6 rotates in the opposite direction, the speaker 1 2 and the speaker 2 3 will move away from each other.

[0040] When the speaker 1 2 and the speaker 2 3 are brought close to each other to a suitable distance, in a larger home theater space, the sound energy is concentrated, the sound pressure level in a specific area is enhanced, and the sound is louder and clearer.

[0041] On the contrary, when the speaker 1 2 and the speaker 2 3 are moved away from each other to a suitable distance, the sound can be more clearly separated in the left and right directions, thereby improving the layering of the sound and enhancing the stereo effect.

[0042] When the speaker 1 2 and the speaker 2 3 move away from each other and gradually approach and fit with the orientation adjustment component 2 5, the left outer wall of the speaker 1 2 will fit with the corresponding orientation adjustment component 2 5, and under the guidance of the orientation adjustment component 2 5, it will begin to deflect counterclockwise with the shaft seat 10 as the axis. Then the speaker 1 2 and the speaker 2 3 deflect synchronously, and the deflection angles of the two are exactly opposite.

[0043] When the speaker 1 2 and the speaker 2 3 move away from each other and gradually approach and fit with the orientation adjustment component 1 4 , the speaker 1 2 will deflect clockwise, while the speaker 2 3 will deflect in the opposite direction to the speaker 1 2 .

[0044] By deflecting the angles of the speaker 1 2 and the speaker 2 3 , the corresponding effects can be further enhanced when the two speakers are moved away from or close to each other by a certain distance.

[0045] The side surface of the speaker 2 is in an arc state, and when it contacts the guide roller 16, it can smoothly complete the deflection work under the rotation of the guide roller 16. When the speaker 2 is deflected, it will drive the receiving plate 11 to rotate, and the receiving plate 11 will drive the positioning block 14 to compress the reset spring 13. When the speaker 2 is out of contact with the guide roller 16, it will be reset under the reset force of the reset spring 13.

[0046] 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 depart from the spirit of the present invention are within the scope of protection of the present invention.
