Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts belong to the scope of protection of the present utility model.

[0030] Please refer to Figures 1 to 5 , the present utility model provides a technical solution: a speaker that is convenient to adjust the angle, with a control terminal 100 for inputting to the speaker, and further includes

[0031] a speaker adjustment mechanism 200, the speaker adjustment mechanism 200 includes a speaker body 210, the speaker body 210 includes a front shell 211 and a rear shell 212, and a top cover 218 is fixedly installed on the top of the front shell 211 and the rear shell 212;

[0032] an adjustment and placement assembly 220 is arranged on the top of the speaker body 210, the adjustment and placement assembly 220 includes a placement plate 225, both sides of the bottom of the placement plate 225 are respectively fixedly connected with rotating shaft plates 226, the middle of the rotating shaft plates 226 is rotationally connected with a fixed shaft plate 221 in a limited manner, the fixed shaft plate 221 is fixedly installed on the top of the top cover 218, and the control terminal 100 is placed on the placement plate 225 in a fitting manner;

[0033] The bottom of the speaker body 210 is limitedly and rotationally installed with an adjustment and rotation assembly 230. The adjustment and rotation assembly 230 includes a base 231, and the base 231 is limitedly and rotationally installed at the bottom of the front shell 211 and the rear shell 212.

[0034] When the user lies on the sofa and uses the speaker, the placement board 225 can be adjusted to a lower inclination angle, making the control terminal 100 easier to operate and the viewing angle more comfortable.

[0035] Please refer to Figures 3 to 5 , the speaker body 210 further includes speakers 213. The speakers 213 are symmetrically installed on both inner sides of the front shell 211 and the rear shell 212. Passive radiators 214 are respectively installed on the backs of the speakers 213, and the passive radiators 214 are installed inside the rear shell 212.

[0036] A battery compartment 215 is provided in the middle of the speaker 213. A through hole matching the battery compartment 215 is opened at the lower part of the back of the rear shell 212. The battery compartment 215 is embedded and installed in the rear shell 212. One side of the battery compartment 215 is electrically connected to a power supply board 216, and a cover plate 217 is installed above the battery compartment 215. Installation posts are provided at the inner bottom of the top cover 218, and the installation posts are installed with the front shell 211 and the inside of the rear shell 212 through screws. An amplifier circuit board 219 is provided inside the top cover 218. The amplifier circuit board 219 is respectively electrically connected to the speaker 213 and the power supply board 216, and an output charging port is provided on the amplifier circuit board 219.

[0037] The control terminal 100 (such as a mobile phone, a tablet computer, etc.) transmits an audio signal into the amplifier circuit board 219 in the speaker body 210 through Bluetooth or other wireless connection methods. After receiving the audio signal, the amplifier circuit board 219 amplifies and processes it to drive the speaker 213 to work. In this process, the amplifier circuit board 219 adjusts parameters such as volume and tone according to the characteristics of the audio signal to ensure that the output sound quality reaches the best effect.

[0038] The battery compartment 215 provides power support for the entire audio playback system. The battery in the battery compartment 215 stably supplies electrical energy to the amplifier circuit board 219 and other components that require power (such as the drive unit of the speaker 213, etc.) through the power supply board 216. The power supply board 216 plays roles such as voltage stabilization and filtering, ensuring the quality of the electrical energy and preventing problems such as voltage fluctuations from affecting the audio playback effect.

[0039] The audio signal processed by the power amplifier circuit board 219 drives the speaker 213 to vibrate. The diaphragm in the speaker 213 vibrates according to the variation law of the audio signal, thereby pushing the surrounding air to generate sound waves. Since the speaker 213 is symmetrically installed on both inner sides of the front shell 211 and the rear shell 212, the sound waves will propagate in different directions, forming a broad sound field. During this process, the passive radiator 214 will generate corresponding movements along with the vibration of the speaker 213. When the speaker 213 pushes the air outwards, the passive radiator 214 will move inwards, and vice versa. This coordinated movement enhances the bass effect, making the sound richer and fuller. The sound waves are transmitted to the surrounding environment through the sound outlet holes on the front shell 211 and the rear shell 212, enabling users to hear music or other audio content.

[0040] An ambient light ring is provided between the top cover 218 and the front shell 211 and the rear shell 212. The ambient light ring is electrically connected to the power amplifier circuit board 219. The switch and the output charging port of the ambient light ring are both arranged on the power amplifier circuit board 219. The top cover 218 is provided with corresponding through holes at the switch and the output charging port. The ambient light ring is electrically connected to the power amplifier circuit board 219. The power amplifier circuit board 219 controls the light change of the ambient light ring according to parameters such as the rhythm and volume of the audio signal. For example, when the music rhythm is fast and the volume is large, the ambient light ring may flash faster and the color may be more vivid; when the music rhythm is slow and gentle, the light change of the ambient light ring will also become correspondingly gentle. This synchronous change of the light and the music is realized through the control circuit in the power amplifier circuit board 219. The control circuit analyzes the audio signal, extracts characteristic information such as rhythm and volume, and then converts this information into a signal for controlling the ambient light ring according to a preset algorithm, thereby realizing the interactive effect between the light and the music.

[0041] The adjustment placement assembly 220 further includes a limit nut cylinder 222. The limit nut cylinder 222 is limit-mounted in the middle of the fixed shaft plate 221. The placement plate 225 is limit-rotatably clamped to both sides of the fixed shaft plate 221 through a rotating shaft plate 226. Anti-wear rings 224 are respectively arranged on both sides of the fixed shaft plate 221. The anti-wear rings 224 are coaxially arranged with the limit nut cylinder 222, and the anti-wear rings 224 are respectively located inside the rotating shaft plate 226. Locking screws 223 are respectively penetrated through the outer sides of the rotating shaft plates 226. The locking screws 223 respectively penetrate through the anti-wear rings 224 and are threadedly connected to both ends of the limit nut cylinder 222. The inner sides of the ends of the locking screws 223 are abutted against the rotating shaft plates 226. The inner side wall of the outer side of the rotating shaft plate 226 is provided with a step. The bearing surface of the head of the locking screw 223 is abutted against the step surface. The locking screw 223 presses the rotating shaft plate 226 to make the rotating shaft plate 226 closely fit with the anti-wear ring 224, so as to make the rotating shaft plate 226 have a certain resistance when rotating, and avoid the placement plate 225 from rotating randomly.

[0042] The adjustment and rotation assembly 230 further includes a turntable 232. The bottom of the turntable 232 is fixedly installed on the base 231. Above the turntable 232, a turntable cover 233 is installed. The top of the turntable cover 233 is fixedly installed with the inner bottom of the front shell 211 and the rear shell 212. The base 231 is rotationally installed with the front shell 211 and the rear shell 212 through the turntable 232. When the user needs to rotate the speaker body 210 horizontally, only a certain external force needs to be applied to make the speaker body 210 rotate around the turntable 232. The bottom of the turntable 232 is fixedly installed on the base 231, and the upper part is fixedly connected to the inner bottom of the speaker body 210 through the turntable cover 233. This structure ensures the stability of the speaker body 210 during the rotation process. When used outdoors, if the user moves from one side of the speaker to the other side, or the position of the crowd changes, the user can adjust the sound propagation direction by rotating the speaker body 210 so that the sound can always cover the target area.

[0043] Working principle: When the user needs to adjust the angle of the control terminal 100 placed on the placement plate 225 on the top of the speaker body 210, the placement plate 225 can rotate around the fixed shaft plate 221. The user can adjust the placement plate 225 to a suitable inclination angle according to their own needs, and at the same time adjust the tightness of the locking screw 223 according to the weight of their mobile phone or tablet to prevent the placement plate 225 from rotating randomly.

[0044] The base 231 at the bottom of the speaker body 210 is rotationally installed with limited rotation with the front shell 211 and the rear shell 212 through the turntable 232. When the user needs to rotate the speaker body 210 horizontally, only a certain external force needs to be applied to make the speaker body 210 rotate around the turntable 232.

[0045] The above is only the preferred embodiment of the present invention and is not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
