Abstract
Claims
1. An outdoor waterproof speaker, comprising a speaker enclosure, wherein a sound outlet cover is fixedly installed on the front side of the speaker enclosure; characterized in that: The inner side of the sound outlet cover is equipped with a waterproof baffle that slides and lifts. Both the sound outlet cover and the waterproof baffle are formed with a number of sound outlet holes. When the waterproof baffle rises, the sound outlet holes of the sound outlet cover and the sound outlet holes of the waterproof baffle are aligned with each other. When the waterproof baffle falls, the sound outlet holes of the sound outlet cover and the sound outlet holes of the waterproof baffle are staggered. The upper part of the sound outlet cover is formed with a vertical sliding groove, and the upper end of the waterproof baffle is formed with a toggle block, which is slidably installed in the vertical sliding groove.
2. The outdoor waterproof sound system according to claim 1, wherein: A widening block is provided on the side of the vertical slide groove. The widening block is integrally formed on the front side of the sound outlet cover plate. A spring plate mounting groove is formed on the side of the widening block near the vertical slide groove. A metal spring plate is installed in the spring plate mounting groove with a clearance fit. The metal spring plate is set to abut against the toggle block.
3. The outdoor waterproof sound system of claim 2, wherein: The metal spring has outward-flaring flanges at both the top and bottom ends, and the middle part of the metal spring is bent into a "U" shape. The "U" shape of the metal spring abuts against the actuating block for limiting its position.
4. The outdoor waterproof sound system of claim 3, wherein: The "U"-shaped structure of the metal spring is located in the middle of the vertical slide groove. The metal spring restricts the actuating block to the upper or lower end of the vertical slide groove through the "U"-shaped structure.
5. The outdoor waterproof sound system according to any one of claims 3-4, wherein: An elastic element is installed between the metal spring and the spring mounting slot.
6. The outdoor waterproof sound system of claim 5, wherein: There are three elastic elements. The inner sides of the outward flanges at both ends of the metal spring are formed with first recessed grooves. The inner side of the "U"-shaped structure of the metal spring is formed with second recessed grooves. The spring mounting groove is formed with three third recessed grooves. The outer ends of the three elastic elements abut against the second recessed grooves and the two first recessed grooves respectively. The inner ends of the three elastic elements abut against the third recessed grooves respectively.
7. The outdoor waterproof sound system according to any one of claims 3-4, wherein: The included angle between the two sides of the "U"-shaped structure is an obtuse angle, and the outer side of the toggle block is formed with a rounded chamfer. When the toggle block is raised or lowered, the rounded chamfer and the "U"-shaped structure press the metal spring sheet.
