It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0028] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0029] like Figure 1-3 The following are examples provided by the present invention.

[0030] The embodiment of the present utility model provides a projector, comprising: a projector body 10, a speaker base 20 and a turntable 30. The projector body 10 is cylindrical, the speaker base 20 is elliptical, the width of the speaker base 20 is less than the length of the projector body 10, and the length of the projector body 10 is less than or equal to the length of the speaker base 20. The projector body 10 is mounted on the speaker base 20 via the turntable 30. The volume and weight of the speaker base 20 are both greater than those of the projector body 10, so that the overall center of gravity of the projector is lowered and it is not easy to tip over. Specifically, a damping shaft 11 is provided at the bottom of the projector body 10, and a shaft sleeve 31 is provided at the top edge of the turntable 30 obliquely upward and outward. The shaft sleeve 31 is hinged to the damping shaft 11. The damping shaft 11 is a common product or part on the market. The shaft sleeve 31 cooperates with the damping shaft 11 so that the projector body 10 can swing up and down relative to the audio base 20 around the shaft sleeve 31, and the projector body 10 can stay at any angle after rotating to fix the projector body 10 at this angle; a rotating groove 21 is provided at the top of the audio base 20, and the turntable 30 is rotatably connected in the rotating groove 21. The size and depth of the rotating groove 21 are matched with the turntable 30, and the turntable 30 is not easy to fall out of the rotating groove 21. The projector body 10 can swing left and right relative to the audio base 20 with the turntable 30, and it is not easy for the projector as a whole to tilt or tip over due to a change in the center of gravity.

[0031] Furthermore, a limiting post 32 is provided at the bottom of the turntable 30, and an arc-shaped limiting hole 22 concentric with the rotating groove 21 is opened at the bottom. The limiting post 32 is slidably connected in the arc-shaped limiting hole 22 to limit the rotation angle of the turntable 30, thereby preventing the various wires connecting the audio base 20 and the projector body 10 from twisting and tangling.

[0032] Furthermore, the vertical distance from the center of the turntable 30 to the shaft sleeve 31 is greater than or equal to the shortest distance from the center of the turntable 30 to the side edge of the top surface of the audio base 20. The damping shaft 11 is perpendicular to the axis of the projector body 10. The damping shaft 11 is located at the bottom of the projector body 10 and close to its rear end, so that when the turntable 30 is rotated to a certain specific angle, the damping shaft 11 hinged to the shaft sleeve 31 can be located on a certain side edge of the audio base 20. At this time, the projector body 10 can swing up and down unhindered, and the swing angle range is also larger.

[0033] Furthermore, the arc angle of the arc-shaped limiting hole 22 is 90°. When the limiting post 32 is located at one end of the arc-shaped limiting hole 22, the damping shaft 11 is located at one side edge of the top surface of the audio base 20, and the projector body 10 can swing up and down normally. When the limiting post 32 is located at the other end of the arc-shaped limiting hole 22, the damping shaft 11 is close to the middle of the top surface of the audio base 20, and the up and down swing range of the projector body 10 is limited, and it cannot swing or can only swing within a small range. In specific implementation, it can be set according to the shape of the projector body 10 and the audio base 20, so that when the limiting post 32 is located at one end of the arc-shaped limiting hole 22, the length direction of the projector body 10 is exactly perpendicular to the length direction of the audio base 20, and when the limiting post 32 is located at the other end of the arc-shaped limiting hole 22, the length direction of the projector body 10 is exactly parallel to the length direction of the audio base 20.

[0034] Specifically, a wiring opening 33 is provided on the turntable 30 near the sleeve 31, and an arc-shaped wiring hole 23 concentric with it is provided on the bottom of the rotating groove 21. The wiring opening 33 is connected to the arc-shaped wiring hole 23 for connecting various wires between the audio base 20 and the projector body 10.

[0035] Furthermore, the wiring opening 33 and the limiting post 32 are respectively located on opposite sides of the center of the turntable 30, and the arc-shaped wiring hole 23 and the arc-shaped limiting hole 22 are respectively located on opposite sides of the center of the rotating groove 21, so that the various wires connected between the audio base 20 and the projector body 10 can move synchronously with the relative rotation of the projector body 10 and the audio base 20, reducing or avoiding irreversible pulling on the wires.

[0036] Specifically, the arc angle of the arc-shaped wiring hole 23 is greater than or equal to 90°, which is adapted to the rotation angle of the turntable 30, ensuring the movement range of the wire and minimizing the pulling of the wire as much as possible. The width of the arc-shaped wiring hole 23 is greater than the width of the arc-shaped limiting hole 22, reserving sufficient space for wiring. Of course, the length of the wire is generally set to be longer than the distance between the corresponding two connecting parts in the projector body 10 and the audio base 20, so that the wire will not be in a taut state.

[0037] Furthermore, a non-slip pad 24 made of rubber or silicone is provided at the bottom of the speaker base 20. The non-slip pad 24 is in the shape of an elliptical ring, which can increase the friction between the speaker base 20 and the table surface on which the projector is placed, while also reducing the impact of the projector when placed, thereby protecting the speaker inside the speaker base 20.

[0038] Obviously, the embodiments described above are only some of the embodiments of the present invention, rather than all of the embodiments. The preferred embodiments of the present invention are given in the accompanying drawings, but they do not limit the patent scope of the present invention. The present invention can be implemented in many different forms. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned specific embodiments, or to make equivalent replacements for some of the technical features therein. Any equivalent structure made using the contents of the present invention specification and the accompanying drawings, directly or indirectly used in other related technical fields, is also within the scope of protection of the present invention patent.
