DETAILED DESCRIPTION

[0019] 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.

[0020] See also Figure 1-3 The utility model provides a technical solution: a portable loudspeaker, including a loudspeaker body 1, a winding groove 101 is provided on the outer surface of the loudspeaker body 1, an elastic sling 2 is fixedly connected to the inner wall of the winding groove 101, a connecting block 201 is fixedly installed at one end of the elastic sling 2 located at the winding groove 101, a limiting groove 3 is provided on one side of the connecting block 201, a limiting pin 302 is symmetrically slidably installed in the limiting groove 3, a fixing foot 105 is symmetrically fixedly installed on one side of the loudspeaker body 1, a limiting hole 106 is provided in the fixing foot 105, and the limiting hole 106 cooperates with the limiting pin 302.

[0021] In the present embodiment, the winding groove 101 cooperates with the elastic sling 2. When the elastic sling 2 is not needed, the elastic sling 2 can be wound into the winding groove 101 and stored, so as to prevent the elastic sling 2 from scattering. At the same time, storing it in the winding groove 101 can effectively prevent the elastic sling 2 from being entangled with the headphone wire, etc. The limiting hole 106 cooperates with the limiting pin 302 to fix the connecting block 201 on the other side of the loudspeaker body 1, so as to fix the other end of the elastic sling 2. The limiting pin 302 is moved out of the limiting hole 106 to release the restriction on the connecting block 201, so as to facilitate winding the connecting block 201 in the winding groove 101.

[0022] Among them, in order to achieve the purpose of placing the device stably on the desktop, the present device is implemented by the following technical solutions: a support plate 103 is fixedly installed on the front side of the loudspeaker body 1 and near the lower edge, a square magnet 104 is embedded under the support plate 103, rubber sleeves 102 are fixedly installed at the four corners of the loudspeaker body 1, a return spring 301 is fixedly installed between the two limit pins 302, and a displacement handle 303 is fixedly installed on the limit pin 302.

[0023] The support plate 103 can provide a certain supporting force when the loudspeaker body 1 is placed on the desktop, so that the loudspeaker body 1 can be stably placed on the desktop. At the same time, the square magnet 104 embedded and installed at the bottom can be adsorbed on the iron desktop, making the device more stable when placed on the desktop. The return spring 301 can provide a certain thrust for the limit pin 302. The limit pin 302 will move into the limit hole 106 under the thrust, thereby fixing the connecting block 201. The displacement handle 303 can drive the limit pin 302 to move. The rubber sleeve 102 is located at the four corners of the device, which can provide a certain buffering capacity for the device to prevent the device from accidentally falling and being damaged.

[0024] In order to achieve the purpose of adsorbing the device on an iron wall or pillar, the device is implemented by the following technical solution: a hook 4 is fixedly installed behind the loudspeaker body 1, and a circular strong magnet 401 is embedded and installed behind the hook 4.

[0025] The loudspeaker body 1 can be stuck in the user's trouser pocket or belt through the hook 4. The circular strong magnet 401 has a certain magnetic strength and can adsorb the device on an iron wall or a pillar.

[0026] The working principle and use process of the utility model are as follows: when using, the device needs to be placed in a suitable position, and the limit pin 302 can be driven by the displacement handle 303 to move out of the limit hole 106, thereby releasing the restriction on the connecting block 201. At this time, the connecting block 201 can drive the elastic sling 2 to move, and release the elastic sling 2 from the winding groove 101. At this time, the connecting block 201 is inserted between the fixed feet 105, the limit pin 302 is inserted into the limit hole 106, and the other end of the elastic sling 2 is fixed to one side of the loudspeaker body 1. The elastic sling 2 can be slung over the user's shoulder, which is convenient for the operator to carry.
