DETAILED DESCRIPTION

[0023] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0024] When using speakers in outdoor spaces, problems such as sound diffusion and reduced loudness often occur, which affect the sound effects.

[0025] Traditional solutions usually involve adding an extra speaker to the audio system, but this will increase the volume and make it inconvenient to carry. The inventor has proposed a directional speaker suitable for outdoor use to solve the above problem.

[0026] The utility model provides the following preferred embodiments

[0027] like Figure 1 , Figure 2 and Figure 3 As shown, a directional speaker suitable for outdoor use comprises:

[0028] An external box 100, wherein the external box 100 may be supported by wood and covered with a waterproof leather layer;

[0029] The sound body 200 is built into the external box 100;

[0030] A sound amplification component 300 is disposed inside the external box 100, wherein the sound amplification component 300 includes a circular sound amplification port 301, a sound amplification speaker 302, and an electric push rod 303. The sound amplification port 301 is opened on one side of the external box 100, the sound amplification speaker 302 is coaxial with the sound amplification port 301 and is located inside the external box 100, the electric push rod 303 is fixed on the side wall of the external box 100, and the driving end of the electric push rod 303 is connected to the sound amplification speaker 302;

[0031] A position limiting component 400, which is disposed on the external box 100 and is used to limit the position of the external box 100 on the ground;

[0032] An external box 100 is arranged outside the sound system, and the external box 100 houses the sound system and the loudspeaker 302. The closed environment provided by the external box 100 can effectively protect the sound system from impact and rain damage. The loudspeaker 302 is coaxially located with the sound system in the external box 100. The loudspeaker 302 can be extended from the external box 100 by the drive of the electric push rod 303 to achieve directional amplification of the internal sound system and concentrate the sound in a specific direction, thereby improving the loudness and sound effect. After use, the loudspeaker 302 can be retracted into the external box 100 by the electric push rod 303 to reduce the volume of the external box 100 for easy carrying. In addition, a limiting component 400 can be provided to limit the external box 100 on the ground to avoid the external box 100 from tipping over due to the influence of outdoor wind and the large wind resistance of the loudspeaker 302 structure, thereby causing damage to the sound system.

[0033] In this embodiment, Figure 1 , Figure 2 and Figure 3 As shown, universal wheels 500 are provided at the four corners of the bottom of the external box 100. The design of the universal wheels 500 enables the external box 100 to be easily moved on the ground without being restricted by direction, and the position can be flexibly adjusted whether on a flat ground or in an uneven terrain.

[0034] In this embodiment, Figure 1 , Figure 2 and Figure 3 As shown, the limit assembly 400 includes a hand wheel 401, a worm gear 402, a worm 403, a sleeve 404, a screw 405, a nut 406, a bearing plate 407, a telescopic rod 408, and four support rods 409. One end of the nut 406 is fixed to the bottom of the external box 100, one end of the screw 405 is screwed into the nut 406 through a thread, the bearing plate 407 is fixed to the other end of the screw 405, the telescopic rod 408 is fixed between the bearing plate 407 and the external box 100, and the sleeve 404 is fixed to the top of the bearing plate 407. On one side, the outer side of the worm 403 is rotatably connected to the inside of the shaft sleeve 404 through a rotating shaft, the worm wheel 402 is coaxial with the screw rod 405 and sleeved on the outer side of the screw rod 405, and the bottom of the worm wheel 402 is rotatably connected to the top of the bearing plate 407 through a rotating shaft, one end of the worm 403 extends to one side of the worm wheel 402 and meshes with the worm wheel 402, the hand wheel 401 is coaxially fixed to the other end of the worm 403, and four support rods 409 are respectively fixed at the four corners of the bottom of the bearing plate 407, and each support rod 409 has a sharp end 409a at the bottom;

[0035] Among them, under normal conditions, the horizontal height of the sharp end 409a of the support rod 409 should be less than the horizontal height of the bottom of the universal wheel 500. When limiting, the hand wheel 401 drives the worm 403 to rotate, and the worm wheel 402 engages with the worm 403, thereby driving the screw 405 to rotate in the nut 406, so that the screw 405 is rotated outward, exceeds the universal wheel 500 and is inserted into the ground soil, and finally the external box 100 is firmly fixed on the ground, which can ensure the stability of the external box 100 and can also be effectively fixed under different ground conditions, and has significant practical value and technical application prospects.

[0036] In this embodiment, Figure 1 , Figure 2 and Figure 3 As shown, handle grooves 600 are provided on both sides of the external box 100, making it more convenient for the user to carry and move the external box 100. The setting of the handle grooves 600 takes into account the actual needs of the user, allowing the user to easily grasp the box and making it more stable and reliable during carrying.

[0037] The specific working process of the utility model is as follows:

[0038] Driven by the electric push rod 303, the loudspeaker 302 can be extended from the external box 100 to achieve directional amplification of the internal sound and concentrate the sound in a specific direction, thereby improving the loudness and sound effect. After use, the loudspeaker 302 can be retracted into the external box 100 through the electric push rod 303, reducing the volume of the external box 100 and making it easier to carry.

[0039] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
