Description

Technical Field

[0001] The utility model relates to the technical field of sound boxes, in particular to a rotatable sound box. Background Art

[0002] Audio specifically refers to an audio system that is a combination of electrical equipment that produces sound. The development history of audio technology can be divided into four stages: vacuum tubes, transistors, integrated circuits, and field-effect transistors. Due to the rise of industries such as square dancing and live broadcasting, the usage rate of audio has greatly increased. However, it is inconvenient to adjust the direction of the audio when using it, and the entire audio needs to be moved, which is not convenient to use. In addition, the bottom of existing audio is mostly flat. When moving, the entire audio needs to be lifted up and moved, which is more laborious. Utility Model Content

[0003] The technical problem to be solved by the utility model is that the existing sound box is not convenient for adjusting the direction of the sound and is not convenient for moving a short distance.

[0004] In order to solve the above problems, the technical solution adopted by the utility model is a rotatable speaker, including a speaker body, a positioning base is provided under the speaker body, a circular groove is provided on the upper side of the positioning base, a circular deep groove is provided on the upper side of the circular groove, a positioning cylinder is fixed in the middle of the circular deep groove, a positioning column is fixed in the positioning cylinder at the lower side of the speaker body, a bearing is clamped between the positioning column and the inner side of the positioning cylinder, an annular boss is fixed on the inner side of the circular groove at the lower side of the speaker body, a plurality of meshing tooth grooves are provided on the inner side of the annular boss, a transmission motor is fixed at the bottom of the circular deep groove, and a transmission gear meshing with the meshing tooth grooves is fixed at the output end of the transmission motor.

[0005] As a further solution of the utility model: an annular groove is provided on the lower side of the annular boss, a plurality of hemispherical grooves are provided on the upper side of the circular groove at the annular groove, and a plurality of balls are sandwiched between the hemispherical grooves and the annular groove to facilitate smoother rotation of the speaker body.

[0006] As a further solution of the utility model: two wheel grooves are provided on one side of the positioning base, a wheel frame is rotatably provided in the wheel groove, and a roller is rotatably provided at one end of the wheel frame to facilitate the movement of the speaker body.

[0007] As a further solution of the utility model: a handle is fixed on the top of one side of the speaker body, and grip grooves are provided on both sides of the speaker body to facilitate lifting the speaker body.

[0008] As a further solution of the utility model: a plurality of connection ports are opened on one side of the speaker body, and a supporting foot is fixed on the bottom of the positioning base.

[0009] As a further solution of the utility model: the speaker body, the transmission motor and the external power supply are electrically connected.

[0010] Compared with the prior art, the utility model has the following advantages: 1. The patent adds a speaker structure that can be rotated at a fixed position. The transmission motor drives the transmission gear to rotate, and then the transmission gear drives the annular boss to rotate. The annular boss can drive the speaker body to rotate, so that the direction of the speaker can be easily changed;

[0011] 2. A rotatable wheel frame has been added. When the speaker body is not moving, the wheel frame is located on one side of the speaker body. When the speaker body needs to be moved a short distance, the side with the wheel frame can be lifted up to allow the wheel frame to fall down naturally. Then, when the roller touches the ground, the other end of the speaker body can be lifted up by relying on the lever principle, and the speaker body can be moved, which is more labor-saving.
