Description

Technical Field

[0001] This utility model belongs to the field of outdoor audio technology, specifically relating to an adjustable outdoor audio system. Background Technology

[0002] An audio system is an electronic device that converts and amplifies audio signals into sound. It typically consists of three main parts: a signal source, a power amplifier responsible for decoding and power amplification, and speakers that ultimately produce sound. Outdoor speakers are portable amplification devices designed specifically for outdoor environments. They usually have a built-in battery and support wireless connections such as Bluetooth. Their core features are strong waterproof, dustproof, and shockproof capabilities. They also use special acoustic structures to amplify volume and enhance bass, meeting the stringent requirements for battery life, robustness, and sound penetration when used in open spaces.

[0003] Most existing outdoor speakers are non-adjustable, and their fixed-angle speaker units cannot adjust the direction of sound projection according to the situation. For example, when camping, if everyone sits in a circle, a speaker that is fixed to the front will result in poor hearing for people on the sides and behind. Moreover, when the speaker is placed on the ground, its range of sound propagation is limited because its height is not adjustable. Utility Model Content

[0004] In view of the problems mentioned above in the background art, the purpose of this utility model is to provide an adjustable outdoor speaker.

[0005] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:

[0006] An adjustable outdoor speaker includes an outdoor speaker with a telescopic rod on the back, a removable dustproof net on the front, rubber anti-collision strips at each corner, and a detachable rotating disc at the bottom. The rotating disc is rotatably mounted on the top of a movable base. The bottom of the movable base has four placement slots, each containing a foldable telescopic support leg.

[0007] Preferably, the outdoor speaker has a fixing plate at the bottom of both sides, and the outdoor speaker can be detachably installed on the top of the rotating disk through the fixing plate. A control plate is provided in the middle of the other two sides of the outdoor speaker.

[0008] Preferably, the telescopic rod includes a sleeve rod and an inner rod. The inner rod is telescopically disposed inside the sleeve rod. Both ends of the sleeve rod are provided with mounting plates. The mounting plates are fixed to the back of the outdoor speaker by anchors. The top of the inner rod is provided with a handle. The handle is provided with a reset button. The reset button cooperates with the locking mechanism of the inner rod.

[0009] Preferably, the dustproof net is provided with fixing bolts at all four corners.

[0010] Preferably, the top of the rotating disk is provided with a mounting groove, which is adapted to the fixing plate.

[0011] Preferably, the bottom of the mobile chassis is fixedly mounted with casters via threaded holes and fasteners, and a drive motor is installed inside the mobile chassis, with the power output end of the drive motor connected to the rotating disk.

[0012] Preferably, a limiting post is provided at one end of the placement groove.

[0013] Preferably, the top end of the telescopic outrigger is provided with a connector, which is folded and placed inside the placement groove by a limiting post, and the bottom end of the telescopic outrigger is provided with a base.

[0014] This invention utilizes a rotating disc at the bottom of the outdoor speaker, enabling horizontal rotation adjustment. This allows for flexible adjustment of the sound projection direction based on the site conditions, effectively solving the problem of uneven sound due to a fixed orientation and significantly improving the user experience. Simultaneously, the placement slot on the mobile chassis and the foldable telescopic legs allow the legs to fold and be stored in the slot during transport, reducing space occupation and facilitating carrying. In use, the legs can rotate 90 degrees to extend, raising the entire speaker unit and increasing its height above the ground, allowing sound to travel further and expanding coverage, overcoming the limitations of insufficient height when placed on the ground. Furthermore, the combination of the telescopic rod and the mobile chassis facilitates movement and transportation, the casters ensure flexible steering, the removable dustproof net facilitates cleaning and maintenance, and the rubber anti-collision strips provide collision protection.
