[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] The utility model provides a portable outdoor speaker. Figure 1-Figure 4 As shown, it includes a box body 1, a panel 2 is installed on the top of the box body 1, a speaker plate 3 is installed on the front of the box body 1 for installing a sound speaker, a support leg 11 and a lifting pulley assembly 7 are installed at the bottom of the box body 1 for supporting or moving the bottom of the box body 1, a host control module 6 is installed inside the box body 1 for controlling the sound playback of the speaker assembly, and the lifting pulley assembly 7 includes a base 71, a universal wheel 72 is installed at the bottom of the base 71, and a sleeve 73 is sleeved on the top of the base 71. The top of 73 is fixed to the bottom of the box body 1, and the height of the universal wheel 72 is adjusted by raising and lowering the base 71, so that the bottom end of the universal wheel 72 is higher or lower than the bottom end of the support leg 11. When it needs to be moved, the bottom end of the universal wheel 72 is lower than the bottom end of the support leg 11 so that the universal wheel 72 contacts the ground and it can be moved. If fixed support is required, the bottom end of the universal wheel 72 is higher than the bottom end of the support leg 11 so that the support leg 11 contacts the ground, thereby stably supporting the box body 1.

[0025] In this embodiment, a handle 21 and a control button 22 are installed on the top of the panel 2. The handle 21 is convenient for carrying the speaker, and the control button 22 is convenient for controlling the speaker.

[0026] Specifically, the speaker board 3 is equipped with a main speaker 31 , a secondary speaker 32 and a display screen 4 for making sounds and displaying data.

[0027] Furthermore, the front corner of the speaker plate 3 close to the box body 1 is an arc-shaped structure, and a corner protection plate 5 is installed on the outer side of the back corner of the box body 1, which has a good protective effect and avoids bumps during transportation.

[0028] Furthermore, the speaker plate 3, the panel 2, and the corner protection plate 5 are all connected to the box body 1 by bolts, so as to facilitate disassembly and maintenance.

[0029] Furthermore, the outer wall of the sleeve 73 is provided with a vertical adjustment hole 74, an upper groove 741 is provided on one side of the upper end of the adjustment hole 74, and a lower groove 742 is provided on one side of the lower end of the adjustment hole 74. A positioning column 75 is installed on the outer wall of the base 71, and the positioning column 75 is slidably matched with the adjustment hole 74 to facilitate the up and down sliding adjustment of the base 71. When the positioning column 75 moves to the upper and lower ends of the adjustment hole 74, the rotating base 71 can clamp the positioning column 75 into the corresponding upper groove 741 or lower groove 742 to realize the positioning of the universal wheel 72.

[0030] Furthermore, the lower inner wall of the upper slot 741 and the upper inner wall of the lower slot 742 are both arc-shaped structures, and the curvature is adapted to the curvature of the positioning column 75 to ensure that the positioning column 75 fits the upper slot 741 or the lower slot 742 .

[0031] Furthermore, the main speaker 31 is located in the middle of the speaker plate 3 , and the number of the auxiliary speakers 32 is four, and they are located at four positions of the main speaker 31 , namely, the top, bottom, left and right, to ensure that the sound can be emitted evenly.

[0032] When the portable outdoor speaker of the utility model is used, first when the user uses the speaker, the control button 22 or an external device (such as a mobile phone, a computer, etc.) will first send a play command to the host control module 6. After receiving the command, the host control module 6 will process the audio signal and emit sound through the main speaker 31 and the auxiliary speaker 32 on the speaker board 3. The display screen 4 will display the current play status and other related information.

[0033] When the user needs to move the speaker to another location, the lifting pulley assembly 7 can be adjusted. Specifically, the positioning column 75 on the base 71 is unscrewed from the upper slot 741, and then the base 71 is slid along the adjustment hole 74 of the sleeve 73 until the bottom end of the universal wheel 72 is lower than the bottom end of the support leg 11. At this time, the base 71 is rotated so that the positioning column 75 is snapped into the lower slot 742 to fix the position of the base 71. Now, the user can easily push or pull the speaker through the handle 21, and the universal wheel 72 will roll on the ground to achieve rapid movement of the speaker.

[0034] When the speaker reaches the designated position and needs to be placed stably, the user can adjust the lifting pulley assembly 7 again. Unscrew the positioning column 75 on the base 71 from the lower slot 742, and then slide the base 71 upward until the bottom end of the universal wheel 72 is higher than the bottom end of the support leg 11. Then, rotate the base 71 so that the positioning column 75 is inserted into the upper slot 741, thereby fixing the position of the base 71 and the universal wheel 72. At this time, the support leg 11 will contact the ground, providing stable support for the speaker.

[0035] Finally, it should be noted that the electronic components of the host control module 6, the main speaker 31, the auxiliary speaker 32, etc. in this embodiment are all universal standard parts or parts known to those skilled in the art, and their structures and principles can be known to those skilled in the art through technical manuals or through conventional experimental methods. In the idle part of this device, all the above-mentioned electrical components are connected by wires respectively. The specific connection means should refer to the working sequence between the electrical components in the above-mentioned working principle to complete the electrical connection, which are all well-known technologies in the art.

[0036] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection of the utility model is defined by the attached claims and their equivalents.
