[0015] The present invention will be further described below with reference to the accompanying drawings and some embodiments.

[0016] In Figure 1- Figure 3A speaker is disclosed, comprising a cabinet 1 and a base 2. The speaker has a common portable speaker structure. The cabinet 1 includes several retractable speaker assemblies 102, a central support 101 for supporting the speaker assemblies, and a connecting bracket 104 connecting the central support and the speaker assemblies. The speaker assemblies 102 are commonly connected in parallel circuits and are common speaker amplification and playback devices. Various numbers and types of speaker assemblies 102 can be configured during manufacturing. The bottom end of the central support 101 is fixed to the base. 2. On the upper surface, several speaker assemblies 102 are connected to the outer perimeter of the central support 101. A slide rail 105 is provided upward from the midpoint of the front face of the speaker assembly. The upper and lower ends of the slide rail 105 are respectively provided with grooves 106 for fixing connecting brackets. One end of the connecting bracket 104 is movably mounted on the slide rail 105, and the other end is mounted to the bottom of the central support 101 through a hinge structure. The hinge structure provides a certain degree of mobility, making it easy to unfold or fold up. When manually unfolding or folding up the speaker assembly 102, it can be moved through the grooves 106. To secure it and effectively prevent the speaker assembly 102 from slipping, it also includes a pull plate 103 for connecting several speaker assemblies. The pull plate 103 is made of plastic and has a certain degree of support. The pull plate 103 is disposed on the outside of the speaker assembly 102. A cavity 107 for retracting the pull plate 103 is vertically disposed on the outside of the speaker assembly 102. Each of the four corners of the pull plate 103 is provided with a buckle 108 to fix the pull plate 103 in the cavity 107. The pull plate 103 is made of plastic, such as ABS plastic, and has a certain degree of flexibility. The convenient pull plate 103 is hidden inside the cavity 107. The pull plate 103 is square in shape. When in use, the speaker assembly 102 can be gently pulled to both sides to remove the pull plate 103 from the cavity 107. Then, the clip 108 fixes the pull plate 103 in the cavity 107 to prevent it from falling out. After use, the pull plate 103 can be pushed back into the cavity 107. When unfolded, the pull plate 103 supports several speaker assemblies 102. When folded, the pull plate 103 is hidden inside the cavity 107. The pull plate 103 can be manually unfolded during use and hidden in the cavity 107 after use, making the speaker look more beautiful and neat. When folded, the speaker is more compact and easy to carry.

[0017] In this embodiment, the speaker is wirelessly connected to the mobile terminal, making it more convenient to use. The wireless connection is a common wireless connection method, such as Bluetooth connection.

[0018] In this embodiment, the base 2 and the folded box 1 are integrally formed, making it more aesthetically pleasing when folded up, while also taking up less space and making it more convenient to carry.

[0019] In this embodiment, a switch button 201 is provided on the front end face of the base 2. The switch button 201 is a power button, which makes it easier to control the speaker.

[0020] In this embodiment, the base 2 and the cabinet 1 are made of metal. Using metal material has good durability, is not easy to age, and is not easy to get dusty or contaminant, which can effectively extend the service life of the speaker.

[0021] In this embodiment, the control circuit of this utility model is a common circuit in the field of circuits. The device of this utility model can be connected to an external power source or a built-in battery through a power cord to provide power to the device. Those skilled in the art can implement it, so it will not be described in detail here.

[0022] In practical implementation, this utility model is as follows: When in use, turn on the speaker switch button 201 to connect to the mobile terminal via Bluetooth. Then, slide the speaker assembly 102 upward via the slide rail 105 and fix it with the groove 106. Then, unfold the speaker assembly 102 to both sides to expose the pull plate 103. At this time, the speaker is unfolded, and the sound effect can reach the effect of a normal speaker. When unfolded, the pull plate 103 is fixed inside the groove 106 by the buckle 108. After use, retract the pull plate 103, slide the speaker assembly 102 downward via the slide rail 105, and fix it with the groove 106. At this time, the speaker is folded up, and the speaker is more compact and convenient to carry.

[0023] It is worth noting that in the description of this utility model, "multiple" means two or more, unless otherwise explicitly specified. In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can also refer to a mechanical connection. The circuits described in this utility model are all commonly used circuits in the art, and other related components are all commonly used existing components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0024] It will be apparent to those skilled in the art that this utility model patent is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this utility model patent. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this utility model patent is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be encompassed within this utility model patent. No reference numerals in the claims should be construed as limiting the scope of the claims.
