Technical Field

[0001] This utility model relates to a desktop speaker, specifically a rotatable speaker with negative pressure adsorption. Background Technology

[0002] Desktop speakers are compact audio devices designed specifically for near-field listening and are commonly found on computer desktops and in studios. Existing desktop speakers have a complex and poorly designed structure. Turning them on / off and adjusting the volume can only be done by pressing buttons, making operation inconvenient. Furthermore, existing speakers are generally bulky and lack aesthetic appeal. In addition, the internal speaker units vibrate during operation, causing the entire speaker to shift and become unstable, resulting in a poor listening experience. Therefore, the inventor has improved the structure of desktop speakers. Utility Model Content

[0003] The purpose of this invention is to provide a rotatable speaker with negative pressure suction. This speaker has a simple structure and reasonable design. By rotating the speaker body above the vacuum suction cup, the functions of power on / off and volume adjustment can be realized, making operation more convenient. The rotation of the speaker body can also achieve a certain decompression effect. The design of integrating the vacuum suction cup with the speaker body also makes the speaker body more aesthetically pleasing. By squeezing the air in the base cavity, the base body can be adsorbed onto a smooth wall or glass surface, keeping the speaker body in a fixed state during use. This provides good shock absorption for the speaker body, preventing displacement due to vibration even after long-term operation, making the structure more stable, improving the user experience, and solving the problems mentioned in the above-mentioned technical background.
